proximal tibiofibular joint instability

Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. PMID: 4837930. Anatomic reconstruction of the proximal tibiofibular joint. A new technique. Edina, MN 55435, EAGAN-VIKING LAKES OFFICE When fractures are present, they are more often associated with the posterior ligament and it is important to distinguish these fractures from a posterolateral corner injury. Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. The proximal fibula moves posteromedial with knee extension. Axial fat-suppressed proton density-weighted images demonstrates a poorly defined chronically torn posterior PTFJ ligament (blue arrowhead). In this regard, it is recommended that the strengths of grafts chosen for proximal tibiofibular reconstructions meet or exceed these values. Clinical and Surgical Pearls The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. Exclusion criteria were cadaveric studies, animal studies, basic science articles, editorial articles, review articles, and surveys. The fibular head lies in an angled groove behind the lateral tibial ridge, which helps to prevent anterior fibular movement with knee flexion [7]. Proximal tibiofibular (PTF) joint instability is a rare condition: only 96 cases have been reported in the published literature. Instability of the proximal tibiofibular joint occurs when the ligaments which provide stability to this joint are injured. The posterior capsule is identified with the insertion of the biceps femoris tendon (BFT) and the FCL. The proximal (or superior) tibiofibular joint is a synovial joint between the superior aspects of the tibia and fibula and is one of the multiple sites of cartilaginous and fibrous articulation carrying the name of the tibiofibular joint. Injury to the proximal tibiofibular joint is typically seen in athletes whose sports require violent twisting motions of the flexed knee. Atraumatic instability is more common and often misdiagnosed. However, in chronic cases, immobilization would not be sufficient to achieve this goal. The reconstructive procedure is recommended for patients whose pain is a result of joint instability. government site. Dislocation of the proximal tibiofibular joint is a very uncommon condition that is easily misdiagnosed without clinical suspicion of the injury. The drill is advanced through all 4 cortices. [Progress on diagnosis and treatment of proximal tibiofibular joint dislocation]. 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. What is your diagnosis? Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. Recurrent dislocation of the proximal tibiofibular joint. 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.1,2, Atraumatic dislocation of the proximal tibiofibular joint is easily misdiagnosed when there is no clinical suspicion of the injury, owing to its association with a wide range of symptoms that mirror many common knee injuries. Knee Surg Sports Traumatol Arthrosc. 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. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. If one obtains the diagnosis soon after injury (acutely), immobilization of the knee in extension for a few weeks to try to get the posterior injured ligaments to heal is reasonable. Many common injuries can cause the same symptoms as proximal tibiofibular dislocation; therefore the integrity of the surrounding ligamentous structures should be investigated before a diagnosis is made. History and physical examination are very important for diagnosis. Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. Proximal tibiofibular joint dislocation and instability is an easily overlooked cause of lateral knee pain. Hey - if he is good enough for Olympic and professional athletes..he's good enough for me! Dislocation of the proximal tibiofibular joint is a very uncommon condition that is easily misdiagnosed without clinical suspicion of the injury. For the case discussed in Figure 9 above, stabilization with an adjustable loop cortical fixation device was selected for multiple reasons. 2010 Nov;18(11):1452-5. doi: 10.1007/s00167-010-1049-9. 8600 Rockville Pike PMID: 32061975. The drill guide is directed in a posteroanterior direction toward the anteromedial aspect of the proximal tibia, making sure to avoid the MCL and pes anserinus. All nonsurgical therapies should be attempted before surgical intervention. 48 year-old female with an acute PLC sprain and ACL tear. Clinical Characteristics and Outcomes After Anatomic Reconstruction of the Proximal Tibiofibular Joint. The tibiofibular joints are a set of articulations that unite the tibia and fibula. LaPrade RF, Gilbert TJ, Bollom TS, Wentorf F, Chaljub G. The magnetic resonance imaging appearance of individual structures of the posterolateral knee. What are the findings? Dr. LaPrade and his team have developed an anatomic proximal posterior tibiofibular joint reconstruction procedure. Oksum M, Randsborg PH. 2008 Aug;191(2):W44-51. 2022;8:8. doi: 10.1051/sicotj/2022008. In acute anterolateral PTFJ dislocation without spontaneous dislocation or fracture, closed reduction is performed. Most proximal tibiofibular joint instabilities can be treated with closed reduction and conservative care, but some require internal fixation or soft-tissue reconstruction. 2017 Jul;45(8):1888-1892. doi: 10.1177/0363546517697288. 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. Surgical Management of Proximal Tibiofibular Joint Instability Using an Adjustable Loop, Cortical Fixation Device. Are you sure you want to trigger topic in your Anconeus AI algorithm? The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. In more chronic cases, we have the patient squat down, which can often demonstrate that the proximal tibiofibular joint is being subluxed. Subluxation of the proximal tibiofibular joint. 1991 Nov;20(11):957-60. Dekker TJ, DePhillipo NN, Kennedy MI, Aman ZS, Schairer WW, LaPrade RF. Epub 2020 Feb 13. Kobbe P., Flohe S., Wellmann M., Russe K. Stabilization of chronic proximal tibiofibular joint instability with a semitendinosus graft. Although many patients do not note symptoms during daily activities, symptoms may develop during activities that require sudden changes in direction. The proximal tibiofibular joint ligaments both strengthen the joint and allow it to rotate and translate during ankle and knee motion. Stop Searching under the Streetlight! This answers all my questions! The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. 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. These two bones of the leg are connected via three junctions; The superior (proximal) tibiofibular joint - between the superior ends of tibia and fibula The inferior (distal) tibiofibular joint - between their inferior ends AJR Am J Roentgenol. On the lateral radiograph the fibular head barely intersects the radio-dense line (dotted line) representing the posteromedial margin of the lateral tibial condyle. J Pediatr Orthop B. The anterior tibiofibular ligament (green arrow) is edematous but in continuity. 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. Resnick D, Newell JD, Guerra J Jr, Danzig LA, Niwayama G, Goergen TG. Knee Surgery, Sports Traumatology, Arthroscopy, 18(11), 1452-1455 . The TightRope needle is then passed through to the anteromedial aspect of the tibia until it exits the skin medially. The anterior ligament is composed of three to four bundles and is further reinforced by the anterior aponeurosis arising from the long head of the biceps femoris tendon (BFT).3,4 The posterior ligament is generally composed of three bundles and significantly weaker than the anterior ligament (Figure 3).5 The inherent joint stability is also directly related to the inclination of the articular-surface which is classically defined as horizontal or oblique. The first step in the management of chronic instability of the PTFJ is usually . The surgical treatment for proximal tibiofibular joint instability most often consists of an anatomic reconstruction of the torn ligaments. Same patient as radiographs in Figure 4. 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. Okubo A, Kajikawa Y, Nakajima S, Watanabe N, Yotsumoto T, Oshima Y, Iizawa N, Majima T. SICOT J. Accessibility Numerous disorders of the proximal tibiofibular joint can present as lateral knee pain. 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. History of Atraumatic Injury Nonoperative treatment is associated with persistent symptoms, whereas both fixation and fibular head resection are associated with high complication rates. Protection of the peroneal nerve during surgery helps to prevent injury and relieves symptoms common to this injury. doi: 10.2214/AJR.07.3406. Successful diagnosis of the injury can be improved by a better understanding of the biomechanics of the joint and a clinical suspicion of the injury when symptoms are present. The CPN (red arrowhead) is abnormally flattened with increased T2 signal. All other clinical possibilities should be ruled out before a diagnosis is made. Diagnosis requires careful assessment of radiographs of the knee and tibia (often missed injury). Ogden JA. Instability of the proximal tibiofibular joint . 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. 27 The proximal tibiofibular joint is a synovial membrane-lined, hyaline cartilage articulation that communicates with the knee joint in The treatment of proximal tibiofibular joint instability usually depends upon whether it is an acute or chronic injury. The PTFJ is also unstable on physical examination. 4010 W. 65th St. The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. Quantitative radiographic assessment of the anatomic attachment sites of the anterior and posterior complexes of the proximal tibiofibular joint. Atraumatic subluxation is thought to result from injury to the anterior ligament and to the anterior capsule of the joint, and it can be associated with Ehlers-Danlos syndrome, muscular dystrophy, and generalized laxity. The horizontal variant has been associated with greater surface area and increased rotatory mobility, thus less prone to injury.. Dr. Robert F. LaPrade operated on my right knee in May of 2010. Only gold members can continue reading. 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.
