Clin Orthop Relat Res. PMID: 28321475. Proximal tibiofibular joint dislocation and instability is an easily overlooked cause of lateral knee pain. Treatment is prompt closed reduction with unstable injuries requiring surgical pinning versus soft tissue reconstruction. There are two ways to initiate a consultation with Dr. LaPrade: You can providecurrentX-rays and/or MRIs for a clinical case review with Dr. LaPrade. The most (77% to 90%) PTFJ dislocations and instability were anterolateral/unspecified anterior dislocation or instability. Knee Surg Sports Traumatol Arthrosc. It often appears striated due to the presence of multiple bundles, and it is located just caudal to the anterior arm of the short head of the biceps femoris tendon. J Pediatr Orthop B. Proximal tibiofibular joint (PTFJ) instability is a rare knee injury, accounting for less than 1% of knee injuries. Most commonly, hamstring allografts and autografts are used to reconstruct the proximal tibiofibular joint anatomically. Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. 43 year-old male with lateral knee pain status-post snowboarding injury. The .gov means its official. Proximal Tibiofibular Joint Instability and Treatment Approaches: A Instability of the proximal tibiofibular joint . NCI CPTC Antibody Characterization Program. On MRI, the tibiofibular ligaments are obliquely oriented and extend cephalad from the fibula to the tibia and therefore multiplanar evaluation is essential.10 The anterior ligament is more readily identified given that it is thicker than the posterior ligament. The relative avascularity of the area of the proximal tibiofibular joint prevents the presentation of knee effusion with an isolated injury, but there may be a prominent lateral mass.1 Anterolateral dislocations often manifest with severe pain near the proximal tibiofibular joint and along the stretched biceps femoris tendon, which may appear to be a tense, curved cord.1 Dorsiflexing and everting the foot, as well as extending the knee, emphasize pain at the proximal tibiofibular joint. In fact 2 years ago I finished climbing the top 100 peaks in CO. The clinical presentation of joint injury can range from common idiopathic subluxation with no history of trauma, to less common high-energy traumatic dislocations that may be associated with long bone fracture. Federal government websites often end in .gov or .mil. Careers. The fibular head lies in an angled groove behind the lateral tibial ridge, which helps to prevent anterior fibular movement with knee flexion [7]. The reconstructive procedure is recommended for patients whose pain is a result of joint instability. In cases where the symptoms of proximal tibiofibular joint instability are difficult to discern, especially for chronic cases, we have found that taping of the proximal tibiofibular joint is helpful to confirm the diagnosis. Tibiofibular joints: Anatomy, movements | Kenhub 27 The proximal tibiofibular joint is a synovial membrane-lined, hyaline cartilage articulation that communicates with the knee joint in Proximal Tibiofibular Joint Instability | Knee Specialist | Minnesota In acute cases, it may be difficult to make the patient relax sufficiently to be able to examine for proximal tibiofibular joint instability, but usually having the knee flexed to 90 degrees and trying to perform an anterolateral subluxation maneuver of the proximal tibiofibular joint is sufficient to confirm this diagnosis. Epub 2018 Jul 23. Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. The CPN (red arrowhead) is abnormally flattened with increased T2 signal. PMID: 1749660. Traumatic dislocations commonly cause pain along the lateral knee that radiates into the region of the iliotibial band and the patellofemoral joint and is increased with palpation of the prominent fibular head and ankle motion.4 The patients pain commonly limits the range of motion, especially knee extension, and motion of the ankle; the patients ability to bear weight on the affected leg is also limited by pain. Most proximal tibiofibular joint instabilities can be treated with closed reduction and conservative care, but some require internal fixation or soft-tissue reconstruction. 2018 Feb 26;7(3):e271-e277. Epub 2020 Feb 13. Limit patients to passive flexion until 6 weeks to reduce the stress that is applied to the reconstructed ligaments (prevent biceps femoris from pulling on the fibular head). Anatomic reconstruction of chronic symptomatic anterolateral proximal tibiofibular joint instability. Limit patients to passive flexion until 6 weeks to reduce the stress that is applied to the reconstructed ligaments (prevent biceps femoris from pulling on the fibular head). 2008 Aug;191(2):W44-51. While the role of the fibula and the posterolateral corner (PLC) in maintaining knee stability has received widespread attention, the contribution of the proximal tibiofibular joint to knee stability is often overlooked and injuries may easily go unnoticed. The forgotten joint: quantifying the anatomy of the proximal tibiofibular joint. The arthrodesis procedure is recommended for patients in whom the correction of joint instability would not relieve pain, such as patients with proximal tibiofibular joint arthritis. A chronically injured CPN may appear atrophic with abnormally increased T2 signal as well as an abnormal contour due to surrounding scar tissue which often effaces the normal perineural fat. Published by Elsevier Inc. All rights reserved. The proximal fibula moves posteromedial with knee extension. 3D renders demonstrate posterior proximal tibiofibular reconstruction using LaPrades technique (12A). Dislocation of the Proximal Tibiofibular Joint - Musculoskeletal Key PMID: 20440223. Most patient histories do not reveal any mechanism of injury to the proximal tibiofibular joint, and symptoms of lateral knee pain can be very misleading. The Proximal Tibiofibular Joint: A Biomechanical Analysis of the 38 year-old with chronic posterolateral corner instability status-post failed FCL reconstruction with partially visualized fixation screw. The posterior ligament attaches to the fibula medial to the styloid and inferomedial to the insertion of the popliteofibular ligament.11 The integrity of the FCL and biceps femoris tendons should also be evaluated as posterolateral corner injuries will often demonstrate soft tissue edema surrounding the joint without disruption of the proximal tibiofibular ligaments. 2014 Sep;472(9):2691-7. doi: 10.1007/s11999-014-3574-1. PMID: 32061975. What are the findings? The treatment of proximal tibiofibular joint instability usually depends upon whether it is an acute or chronic injury. Atraumatic instability is more common and often misdiagnosed. 2023 Mar 13;18(1):196. doi: 10.1186/s13018-023-03684-x. Initial management of traumatic joint dislocation should involve closed reduction under local anesthesia, followed by surgical intervention if reduction fails. On the AP radiograph, the fibula should overlap the lateral margin of the lateral tibial condyle and lateral displacement will widen the interosseous space. 2020 Jun;36(6):1649-1654. doi: 10.1016/j.arthro.2020.01.056. More commonly, however, AP and lateral radiographs are performed (Figure 4). Dr LaPrade performed a deep root repair to my meniscus, which saved me from a knee replacement at this time. In chronic injuries, the instability may appear obvious when the patient performs a maximal squat. AP weightbearing radiographs of both knees and lateral radiograph of the right knee in a 31-year-old female who fell while skiing. Improved outcomes can be expected after surgical treatment of PTFJ instability. Patients with subluxation of the proximal tibiofibular joint commonly report pain over the joint that is aggravated by direct pressure over the fibular head. Axial and coronal fat-suppressed proton density-weighted images demonstrate soft tissue edema surrounding the PTFJ with subtle irregularity of the posterior ligament (blue arrow) near the fibular attachment and an underlying bone contusion (arrowhead). With acute injury, patients usually complain of pain and a prominence in the lateral aspect of the knee. The tibiofibular joints are a set of articulations that unite the tibia and fibula. My right knee was totally destroyed; ACL, MCL, PCL all severely torn; the patella was the only thing intact in my right knee. The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. During significant trauma, traumatic dislocations of the tibiofibular joint are commonly missed, so the physical examination of this joint is a significant part of the comprehensive knee examination. Treatment for proximal tibiofibular joint stability requires that nonsurgical management be attempted first for patients with atraumatic subluxation of the proximal tibiofibular joint. Instability of this joint may be in the anterolateral, posteromedial, or superior directions. During significant trauma, traumatic dislocations of the tibiofibular joint are commonly missed, so the physical examination of this joint is a significant part of the comprehensive knee examination. In order to ensure that the ligament heals without having it stretch out, it is recommended that the patients be non-weight or toe-touch weight bearing for the first six weeks to ensure that the joint is not overloaded to allow the reconstruction graft to start to heal in the tunnels. The diagnosis is often unknown and delayed due to its variable and . PMID: 10750995. Clin Orthop Relat Res. Only gold members can continue reading. Patients often report symptoms such as knee instability and giving way during these activities, as well as clicking and popping during daily activities.3 We recommend joint reconstruction to repair the proximal tibiofibular joint, which will retain the functional anatomy and rotation of the joint, over arthrodesis, especially in children and athletes. Proximal tibiofibular ligament reconstruction, specifically biceps rerouting and anatomic graft reconstruction, leads to improved outcomes with low complication rates. History and physical examination are very important for diagnosis. Injury to the proximal tibiofibular joint can lead to lateral knee pain and instability owing to chronic rupture of the posterior tibiofibular ligament. Instability of this joint may be in the anterolateral, posteromedial, or superior directions. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. PMID: 4837930. In more chronic cases, we have the patient squat down, which can often demonstrate that the proximal tibiofibular joint is being subluxed. It is common for patients to also have transient peroneal nerve injuries, especially with posteromedial dislocation.1,2 Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. Proximal Tib-Fib Dislocation - Knee & Sports - Orthobullets The proximal tibiofibular joint is a synovial sliding joint which dissipates torsional forces applied at the ankle and tensile forces generated during lateral tibial bending moments.2 The joint is stabilized by multiple ligaments including the anterior and posterior tibiofibular ligaments as well as the fibular collateral ligament (FCL).

The proximal tibiofibular joint (PTFJ) is the articulation of the lateral tibial plateau of the tibia and the head of the fibula. However, I will always be thankful to Dr. Shirzad for at least examining my proximal tib-fib joint and his supportive chart note acknowledging the pain upon palpation. Epub 2017 Mar 24. In the past, chronic instability was treated with arthrodesis or fibular head resection; however, complications related to altered knee and ankle biomechanics rendered these options less desirable.13,14,15, As knee ligament reconstruction surgery has developed, various techniques to reconstruct the ligaments have been described. In acute anterolateral PTFJ dislocation without spontaneous dislocation or fracture, closed reduction is performed. Proximal tibiofibular stabilization by anatomical ligamentoplasty and In general, we prefer an autograft (using ones own tissues) because it will heal in faster than an allograft (cadaver graft). History of Atraumatic Injury Subluxation of the proximal tibiofibular joint. 2016 May-Jun;40(3):470-6. doi: 10.1016/j.clinimag.2015.12.011. Proximal tibiofibular joint dislocation and instability is an easily overlooked cause of lateral knee pain. Proximal Tibiofibular Joint Instability and Treatment Approaches: A Systematic Review of the Literature Authors: Bradley M. Kruckeberg Mayo Clinic - Rochester Mark Cinque Stanford Medicine. On the AP radiographs the right knee demonstrates decreased overlap between the fibular head and the lateral tibial condyle compared with the left indicating that the fibular head is displaced laterally. For the treatment of PTFJ instability, there were 18 studies (35 patients) describing nonoperative management, 3 studies (4 patients) reported on open reduction, 11 studies (25 patients) reported on fixation, 4 studies (10 patients) that described proximal fibula resection, 3 studies (11 patients) reported on adjustable cortical button repair, 2 studies (3 patients) reported on ligament reconstructions, and 5 (8 patients) studies reported on biceps femoris tendon rerouting. A spectrum of sports-related injuries resulting in anterolateral dislocation occur due to a violent twisting of the flexed knee with an inverted foot. A proximal tib-fib dislocation is a disruption of the proximal tibia-fibula joint associated with high energy open fractures of the tibia and peroneal nerve injury. Clinical and Surgical Pitfalls The BFT, FCL, and nerve are inspected, and the wound is closed in layers. Marchetti DC, Chahla J, Moatshe G, Slette EL, LaPrade RF. A prospective study of normal knees and knees with surgically verified grade III injuries. This answers all my questions! Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. In acute cases, we have found that immobilization in a brace in full extension for 3 weeks is often very effective to allow the posterior proximal tibiofibular joint ligament tear to scar in sufficiently such that there is no instability. Suspicion of atraumatic injury to the proximal tibiofibular joint warrants extensive inspection during the physical examination of the knee. With acute injury, patients usually complain of pain and a prominence in the lateral aspect of the knee. Plain radiographs should be taken from anteroposterior, lateral, and oblique (45 to 60 degrees internal rotation of the knee) views, with comparison views from the contralateral knee, or from the preinjury knee if possible.5 When a diagnosis is suspected but not clearly established by plain radiographs, axial computed tomography has been found to be the most accurate imaging modality for detection of injury of the proximal tibiofibular joint.6 Magnetic resonance imaging (MRI) can also confirm a diagnosis of recent dislocation, based on the presence of pericapsular edema of the joint and edema of the soleus at its fibular origin of the popliteus muscle, but this finding is often absent in chronic and atraumatic cases.7, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on Management of Proximal Tibiofibular Instability. The fracture was extremely difficult to visualize on radiographs. Dirim B, Wangwinyuvirat M, Frank A, Cink V, Pretterklieber ML, Pastore D, Resnick D. Communication between the proximal tibiofibular joint and knee via the subpopliteal recess: MR arthrography with histologic correlation and stratigraphic dissection. Gross anatomy Articulation fibula: flat facet of the fibular head Previous attempts to make it better provided only temporary relief. Dr. La Prade had just moved to Vail and I was his 2nd patient @ The Steadman Clinic. A closed reduction should be attempted in patients with acute dislocation. The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. Oksum M, Randsborg PH. Methods such as arthrodesis and fibular head resection have largely been replaced with various . 8600 Rockville Pike Patients who undergo this reconstruction are kept on crutches for 6 weeks with no to minimal weight-bearing movement, but are allowed full range of motion. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. 62.4 Clinical Signs of Proximal Tibiofibular Joint Instability. If one has a chronic proximal tibiofibular joint injury, we prefer to trial taping to validate that the symptoms of the proximal tibiofibular joint injury are improved with the taping program. Are you experiencing proximal tibiofibular joint instability? Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. The TightRope is subsequently tightened by pulling and spreading the sutures until the lateral button reaches the fibular head. Rev Chir Orthop Reparatrice Appar Mot. 4010 W. 65th St. We recommend joint reconstruction to repair the proximal tibiofibular joint, which will retain the functional anatomy and rotation of the joint, over arthrodesis, especially in children and athletes. While protecting the CPN, sharp dissection to the fibular head is performed. Bookshelf Clinical and Surgical Pearls A fibular bone bruise (asterisk) is present near the attachment of the posterior ligament. Zhongguo Gu Shang. Most patient histories do not reveal any mechanism of injury to the proximal tibiofibular joint, and symptoms of lateral knee pain can be very misleading. Plain radiographs should be taken from anteroposterior, lateral, and oblique (45 to 60 degrees internal rotation of the knee) views, with comparison views from the contralateral knee, or from the preinjury knee if possible.5 When a diagnosis is suspected but not clearly established by plain radiographs, axial computed tomography has been found to be the most accurate imaging modality for detection of injury of the proximal tibiofibular joint.6 Magnetic resonance imaging (MRI) can also confirm a diagnosis of recent dislocation, based on the presence of pericapsular edema of the joint and edema of the soleus at its fibular origin of the popliteus muscle, but this finding is often absent in chronic and atraumatic cases.7 This site needs JavaScript to work properly. In addition, patients should avoid any deep squatting, or squatting and twisting, because this puts a significant amount of stress on this joint, for the first four months postoperatively. The posterior ligament is disrupted near the fibular attachment on the axial image with subtle irregularity on the sagittal image. Epub 2005 Dec 22. Patients often report symptoms such as knee instability and giving way during these activities, as well as clicking and popping during daily activities.3, Traumatic dislocations commonly cause pain along the lateral knee that radiates into the region of the iliotibial band and the patellofemoral joint and is increased with palpation of the prominent fibular head and ankle motion.4 The patients pain commonly limits the range of motion, especially knee extension, and motion of the ankle; the patients ability to bear weight on the affected leg is also limited by pain. Just below these structures, the posterior proximal tibiofibular ligament is inspected. A variety of surgical treatments have been proposed over the last decades. ABSTRACT Both the anterior and posterior ligaments may be torn however the posterior ligament is weaker and more often torn (Figures 6-8). Related Proximal tibiofibular joint: anatomic-pathologic-radiographic correlation. Surgical Management of Proximal Tibiofibular Joint Instability Using an Adjustable Loop, Cortical Fixation Device. The reconstructive procedure is recommended for patients whose pain is a result of joint instability. Anterolateral dislocation commonly stems from injury to the anterior and posterior capsular ligaments, and commonly the lateral collateral ligament.1,2 The common cause of traumatic anterolateral dislocation is a fall on a flexed knee, or a violent twisting motion during an athletic activity.3 The hyperflexed knee results in relaxation of the biceps femoris tendon and the lateral collateral ligament, and the violent twisting of the body creates a torque that pushes the fibular head laterally to the edge of the lateral tibial metaphysis.1,2 The forced plantar flexion and ankle inversion forces the laterally displaced fibular head anteriorly.1 The anterior tibiofibular ligament lies just caudal to the anterior arm of the short head of the biceps femoris tendon (purple arrows) which courses anteromedial to the FCL to insert onto the tibia approximately 1 cm posterior to Gerdys tubercle. The first step in the management of chronic instability of the PTFJ is usually . Axial (8A), coronal (8B), and sagittal (8C) fat-suppressed proton density-weighted images. (For a review of the posterolateral corner, please refer to https://radsource.us/posterolateral-corner-injury). Patients with subluxation of the proximal tibiofibular joint commonly report pain over the joint that is aggravated by direct pressure over the fibular head. Anatomic reconstruction of the proximal tibiofibular joint. Concurrent with this, we will perform a Tinels test by percussing over the common peroneal nerve to confirm the presence of dysesthesias or zingers, which translate down the leg. Instability of the Proximal Tibiofibular Joint : JAAOS - Journal of the 2010 Sep;19(5):409-14. doi: 10.1097/BPB.0b013e3283395f6f. Proximal Tibiofibular Taping Example Arthroscopy. Whereas the short and long heads of the biceps do attach the fibular head, they arent in a force vector position well enough to be able to hold the joint stable when one performs deep flexion activities or any rotational activities with the knee bent that involve the proximal tibiofibular joint. eCollection 2022 Sep. Pappa E, Kakridonis F, Trantos IA, Ioannidis K, Koundis G, Kokoroghiannis C. Cureus. MeSH Thank you for choosing Dr. LaPrade as your healthcare provider. Joint subluxation is common in adolescents, typically girls, and results from hypermobility of the joint, in which symptoms can decrease with skeletal maturity.2 Some studies have shown that congenital dislocation of the knee can also be associated with atraumatic superior dislocation of the proximal tibiofibular joint.1, Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. In the past, while others have often treated this instability of this joint by fusing it, we have reported through research that a proximal posterior tibiofibular joint ligament reconstruction is easily performed, does not overconstrain the joint and has decreased the chance of leading to ankle pathology further down the line. Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. Plain radiographs should be taken from anteroposterior, lateral, and oblique (45 to 60 degrees internal rotation of the knee) views, with comparison views from the contralateral knee, or from the preinjury knee if possible. Level IV, systematic review of level IV studies. Proximal tibiofibular dislocation is commonly missed initially when high-energy trauma results in other traumatic fractures as well, such as injury to the tibial plateau or shaft, injury to the ipsilateral femoral head or shaft, ankle fracture, or knee dislocation. Quantitative radiographic assessment of the anatomic attachment sites of the anterior and posterior complexes of the proximal tibiofibular joint. Sequential axial (1A), coronal (1B), and sagittal (1C) fat-suppressed proton density-weighted images are provided through the proximal tibiofibular joint. The anterior-most sagittal image demonstrates the relationship between the anterior arm of the short head of the biceps femoris tendon (purple arrow), the fibular insertion of the FCL (yellow arrow), and the anterior tibiofibular ligament (green arrow). Anatomy of the proximal tibiofibular joint. I have looked many times for answers on my tibial tubercle osteotomy and never found any as detailed as i needed. Soft tissue edema is present in the anterior (green arrow) and posterior (blue arrows) PTFJ ligaments. A fat-suppressed proton density-weighted axial image (12B) demonstrates post-surgical appearance after open PTFJ ligament reconstruction with hamstring autograft (arrows) in a 30 year-old competitive weightlifter with chronic PTFJ instability. You can schedule an office consultation with Dr. LaPrade. Dekker TJ, DePhillipo NN, Kennedy MI, Aman ZS, Schairer WW, LaPrade RF. and transmitted securely. The clinical presentation of joint injury can range from common idiopathic subluxation with no history of trauma, to less common high-energy traumatic dislocations that may be associated with long bone fracture.
