proximal tibiofibular joint instability

The early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. Atraumatic instability is more common and often misdiagnosed. Chronic instability is commonly the result of untreated or misdiagnosed subluxation of the PTFJ. 2019 Feb;27(2):412-418. doi: 10.1007/s00167-018-5061-9. PMID: 4837930. Espregueira-Mendes JD, da Silva MV. Am J Sports Med. PMC This helps us to confirm that the patient does have instability of the proximal tibiofibular joint which may require surgery. Methods: PMID: 28321475. 2008 Aug;191(2):W44-51. Sequential axial (1A), coronal (1B), and sagittal (1C) fat-suppressed proton density-weighted images are provided through the proximal tibiofibular joint. At the time of clinical evaluation, patients report lateral knee pain or instability which invokes a broad differential diagnosis. History and physical examination are very important for diagnosis. 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. Epub 2017 May 10. 1974 Jun;(101):192-7. Epub 2010 Feb 3. The fibular head lies in an angled groove behind the lateral tibial ridge, which helps to prevent anterior fibular movement with knee flexion [7]. Axial images from superior to inferior demonstrate soft tissue edema surrounding the proximal tibiofibular joint. Because the joint is relatively inherently stable because of its bony anatomy when the knee is out straight, most cases of proximal tibiofibular joint instability occur when the knee is bent. ABSTRACT Proximal tibiofibular joint instability is a very unusual and uncommon condition. 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.

Axial fat-suppressed proton density-weighted images demonstrates a poorly defined chronically torn posterior PTFJ ligament (blue arrowhead). The proximal tibiofibular joint (PTFJ) is the articulation of the lateral tibial plateau of the tibia and the head of the fibula. Typically, the proximal tibiofibular joint is injured in a fall when the ankle is plantar-flexed, with the stress being brought through the fibula, will cause the proximal fibula to sublux (partial dislocation) out of place over the lateral aspect of the knee joint. The diagnosis is often unknown and delayed due to its variable and . Related Evaluation of the joint, the supporting ligaments, and the common peroneal nerve should be assessed alongside evaluation of the posterolateral corner. PMID: 18647885. The https:// ensures that you are connecting to the The forgotten joint: quantifying the anatomy of the proximal tibiofibular joint. On the lateral radiograph the fibular head barely intersects the radio-dense line (dotted line) representing the posteromedial margin of the lateral tibial condyle. 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. All nonsurgical therapies should be attempted before surgical intervention. Level of evidence: Taping of the proximal tibiofibular joint, in a reverse direction to pull it away from the tendency to anterolateral subluxation, can be very effective at obtaining a validated clinical response in a patient who has injuries to this joint. Common considerations include lateral meniscus pathology, FCL injury/PLC instability, biceps tendonitis, and distal iliotibial band friction syndrome. Marchetti DC, Moatshe G, Phelps BM, Dahl KD, Ferrari MB, Chahla J, Turnbull TL, LaPrade RF. Flexing the knee to 90 degrees to relax the lateral collateral ligament and biceps femoris tendon, then moving the fibular head anteriorly and posteriorly, can test instability of the 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. EDINA- CROSSTOWN OFFICE A new technique. eCollection 2023 Jan. Mediterr J Rheumatol. Apropos of 3 cases]. Epub 2020 Feb 13. Proximal tibiofibular joint dislocation and instability is an easily overlooked cause of lateral knee pain. 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). On the axial, sagittal, and coronal images, the anterior tibiofibular ligament (green arrows) is diffusely edematous and a portion of the ligament fibers are discontinuous. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. National Library of Medicine Injury to the proximal tibiofibular joint is typically seen in athletes whose sports require violent twisting motions of the flexed knee. 1998. In acute anterolateral PTFJ dislocation without spontaneous dislocation or fracture, closed reduction is performed. 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. Preoperative Considerations 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. Recent traumatic anterolateral proximal tibiofibular joint dislocation. The reconstructive procedure is recommended for patients whose pain is a result of joint instability. 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. 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). [Progress on diagnosis and treatment of proximal tibiofibular joint dislocation]. Proximal tibiofibular ligament reconstruction, specifically biceps rerouting and anatomic graft reconstruction, leads to improved outcomes with low complication rates. In general, reaming a tunnel from front to back (anterior to posterior) through the fibular head and having it exit where the proximal tibiofibular joint posterior ligaments attach, and then drilling another tunnel from front to back on the tibia and which exits posteriorly at the attachment site of the proximal posterior tibiofibular joint ligaments, is the desired location for an anatomic-based reconstruction graft. It causes significant lateral sided knee pain and functional deficits and can be associated with up to 9% of multiligament knee injuries. The TightRope needle is then passed through to the anteromedial aspect of the tibia until it exits the skin medially. Instability of the joint can be a result of an injury to these ligaments. Axial fat-suppressed proton density weighted image at the PTFJ demonstrates marked soft tissue edema surrounding the joint with intact anterior (green arrow) and posterior (blue arrow) PTFJ ligaments. 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.

For the case discussed in Figure 9 above, stabilization with an adjustable loop cortical fixation device was selected for multiple reasons. 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. The drill is advanced through all 4 cortices. 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. Initial management of traumatic joint dislocation should involve closed reduction under local anesthesia, followed by surgical intervention if reduction fails. However, on a true lateral radiograph, the fibular head should intersect a line created by the posteromedial portion of the lateral tibial condyle and anterior or posterior displacement of the fibular head will disrupt this relationship.9 In cases of transient traumatic dislocation, anatomic alignment may be within normal limits and therefore normal radiographic alignment does not exclude the possibility of recent dislocation or instability. 2023 Lineage Medical, Inc.

On the superior axial image, a small amount of fluid (arrowhead) in the fibular collateral ligament (FCL)-biceps femoris bursa delineates the relationship between the anterior arm of the long head of the biceps femoris tendon (orange arrows) and the FCL (yellow arrows). While it is often difficult to identify a complete tear, in the absence of a history of dislocation or instability, edema in the ligaments associated with a fibular bone bruise along the posterior ligament attachment should raise awareness of recent traumatic injury. A sagittal image through the posterior aspect of the PTFJ demonstrates the normal posterior ligament. Internal bracing is performed with a knotless suture button (TightRope syndesmosis implant; Arthrex). PMID: 20440223. 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. The treatment of proximal tibiofibular joint instability depends upon the time of presentation. 13C: Preoperative physical exam video demonstrating gross PTFJ instability (13A), intra-operative physical exam video demonstrating resolution of instability following PTFJ reconstruction utilizing suture button with TightRope fixation (13B), and an AP postoperative radiograph demonstrating restoration of anatomic alignment (compare with preoperative radiograph Figure 4).

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. Chapter Synopsis Fibular resection during an arthrodesis procedure can decrease ankle pain and instability after surgery. I had wanted to do the Proximal Tibiofibular Surgery locally instead of flying out of state. The proximal tibiofibular joint ligaments both strengthen the joint and allow it to rotate and translate during ankle and knee motion. An official website of the United States government. Knee Surgery, Sports Traumatology, Arthroscopy, 18(11), 1452-1455 . Anatomic reconstruction of chronic symptomatic anterolateral proximal tibiofibular joint instability. History of Traumatic Injury 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. Clinical History: 21-year-old male with lateral knee pain radiating into the calf status-post soccer injury. Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. 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. Right Knee Surgery After Auto Bicycle Accident, Medical Second Opinion Service MRI/X-ray Review. We anticipate that our patients will return back to full activities about 4-5 months after surgery, following the rehabilitation program. More commonly, however, AP and lateral radiographs are performed (Figure 4). more common with horseback riding and parachuting, posterior hip dislocation (flexed knee and hip), proximal fibula articulates with a facet of the lateral cortex of the tibia, distinct from the articulation of the knee, joint is strengthened by anterior and posterior ligaments of the fibular head, symptoms can mimic a lateral meniscal tear, comparison views of the contralateral knee are essential, clearly identifies the presence or absence of dislocation, pressure over the fibular head opposite to the direction of dislocation, extension vs. early range of motion (controversial), commonly successful with minimal disadvantages, chronic dislocation with chronic pain and symptomatic instability, rarely occurs and is usually minimally symptomatic, Spontaneous Osteonecrosis of the Knee (SONK), Osgood Schlatter's Disease (Tibial Tubercle Apophysitis), Anterior Superior Iliac Spine (ASIS) Avulsion, Anterior Inferior Iliac Spine Avulsion (AIIS), Proximal Tibiofibular Joint Ganglion Cysts, Pre-Participation Physical Exam in Athlete, Concussions (Mild Traumatic Brain Injury). 31 year-old female status-post fall and twisting injury while skiing with lateral knee pain radiating down the calf. The anterior ligament should be identified in all three planes. The reconstructive procedure is recommended for patients whose pain is a result of joint instability. The diagnosis of proximal tibiofibular joint instability is almost always based on a thorough clinical exam. Concurrent surgical treatment of posterolateral corner (PLC) and PTFJ instability poses technical challenges due to the limited working space . Nonoperative treatment is associated with persistent symptoms, whereas both fixation and fibular head resection are associated with high complication rates. Thank you, Dr. LaPrade, for treating me with the care, focus, and expertise as if I was an Olympic athlete!- From your 63 year old very appreciative patent ~. A Primer and Practical Guide to the Diagnosis of Joint Pain and Inflammation. Only 1 case of atraumatic proximal tibiofibular joint instability in a 14-year-old girl has been reported in the literature, however this condition might occur more frequently than once thought. 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. 8600 Rockville Pike A closed reduction should be attempted in patients with acute dislocation.

A systematic review was performed according to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Careful dissection to the posterior aspect of the joint is carried out after a peroneal nerve neurolysis is performed. Bone marrow contusions along both sides of the joint may or may not be present, and fractures are less common (Figures 9 and 10). doi: 10.7759/cureus.25849. . 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. Knee Surg Sports Traumatol Arthrosc. Orthop Rev. 2023 Mar 13;18(1):196. doi: 10.1186/s13018-023-03684-x. 2018 Apr;26(4):1096-1103. doi: 10.1007/s00167-017-4508-8. Proximal tibiofibular ligamentous abnormalities were present in 100% of acute (< 6 months) and 85.7% of chronic (>6 months) instability cases who underwent MRI. Flexing the knee to 90 degrees to relax the lateral collateral ligament and biceps femoris tendon, then moving the fibular head anteriorly and posteriorly, can test instability of the joint. The vast majority of the time, the torn ligaments are the posterior proximal tibiofibular joint ligaments, so a graft which is placed in the anatomic position to restore these ligaments has been proven to be successful. Furthermore, we excluded studies that did not report patient follow-up time and studies without any patient-reported, clinical or radiographic outcomes at the final follow-up. Epub 2017 Mar 21. The proximal tibiofibular joint (PTJF) can be injured with the structures in the lateral aspect of the knee in a multi-ligament knee injury (MLKI) patient. The posterior ligament (blue arrow) is edematous, the midportion of the ligament is abnormally thinned on the axial, coronal, and sagittal images, and the tibial insertion is torn on the posterior-most coronal image. Morrison T.D., Shaer J.A., Little J.E. A fibular bone bruise (asterisk) is present near the attachment of the posterior ligament. Knee Surg Sports Traumatol Arthrosc. Instability of the joint can be a result of an injury to these ligaments. A prospective study of normal knees and knees with surgically verified grade III injuries. Soft tissue edema is present in the anterior (green arrow) and posterior (blue arrows) PTFJ ligaments. The surgical treatment for proximal tibiofibular joint instability most often consists of an anatomic reconstruction of the torn ligaments. The horizontal variant has been associated with greater surface area and increased rotatory mobility, thus less prone to injury.. The proximal tibiofibular joint should be palpated for tenderness, and laxity should be evaluated by translating the fibular head anteriorly and posteriorly with the thumb and index finger and asking the patient if the symptoms are reproduced or if there is any apprehension. 43 year-old male with lateral knee pain status-post snowboarding injury. Quantitative radiographic assessment of the anatomic attachment sites of the anterior and posterior complexes of the proximal tibiofibular joint. PMID: 28339288. 2017 Oct 25;30(10):972-975. doi: 10.3969/j.issn.1003-0034.2017.10.019. 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. 2018 Feb 26;7(3):e271-e277. Giachino A.A. Recurrent dislocations of the proximal tibiofibular joint. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. Instability of the joint can be a result of an injury to these ligaments. 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). The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. Please enable it to take advantage of the complete set of features! 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. 2022 Sep 30;33(3):291-304. doi: 10.31138/mjr.33.3.291. Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. While protecting the CPN, sharp dissection to the fibular head is performed. We have found it to be very effective at restoring stability to this joint and not resulting in joint overconstraint. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. Zhongguo Gu Shang. When the knee is flexed beyond 30 degrees, relaxation of the FCL and biceps femoris tendons allows the fibula to shift anteriorly which reduces joint stability and allows the fibular head to move approximately 7-10 mm in the anteroposterior plane.6,7 In the event of an added twisting element, external rotation of the tibia pulls the fibula laterally and tension in the anterolateral compartment musculature then further draws the fibula anteriorly.8. This is because there are no muscles that can control the joint for most activities of daily living. 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. Epub 2022 Apr 1. Resnick D, Newell JD, Guerra J Jr, Danzig LA, Niwayama G, Goergen TG. PMID: 29881700; PMCID: PMC5989917. The chief function of the proximal tibiofibular joint is to dissipate some of the forces on the lower leg such as torsional stresses on the ankle, lateral tibial bending movements, and tensile weight bearing. Hey - if he is good enough for Olympic and professional athletes..he's good enough for me! 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 early recognition of instability in the proximal tibiofibular joint is necessary to optimize management of the injury and to avoid potential misdiagnosis. Accessibility The CPN (red arrowhead) is abnormally flattened with increased T2 signal. Nate Kopydlowski and Jon K. Sekiya Instability of this joint may be in the anterolateral, posteromedial, or superior directions. 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. 2700 Vikings Circle What is your diagnosis?
