Instability of the proximal tibiofibular joint is a very rare condition that is often misdiagnosed when there is no suspicion of the injury. 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. Proximal tibiofibular joint (PTFJ) instability is a rare knee injury, accounting for less than 1% of knee injuries. PMC This helps us to confirm that the patient does have instability of the proximal tibiofibular joint which may require surgery. The horizontal variant has been associated with greater surface area and increased rotatory mobility, thus less prone to injury.. My right knee was totally destroyed; ACL, MCL, PCL all severely torn; the patella was the only thing intact in my right 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. PMID: 27133689. Chapter 92 Most commonly, hamstring allografts and autografts are used to reconstruct the proximal tibiofibular joint anatomically. ABSTRACT Abstract Dislocation of the tibiofibular joint is rare and usually results from a traumatic event. Focal edema is seen in the proximal soleus muscle (asterisks) adjacent to the fracture, and edema surrounds the common peroneal nerve (arrowhead). In addition, we frequently perform a common peroneal nerve neurolysis concurrent with the ligament reconstruction to release the scar tissue around the common peroneal nerve so that any further nerve irritation will not occur after surgery due to postoperative swelling or scar tissue entrapment. In the setting of acute injury and subsequent stabilization, the posterior PTFJ ligaments have been shown to scar, thereby precluding the need for a full reconstruction.22 Moreover, the avulsion fracture portends bone-to-bone healing and any reconstruction technique requiring drilling through the posteromedial aspect of the fibular head risks comminuting and further displacing the fracture fragment. Evaluation of the PTFJ on the lateral radiographs is less reliable due to variable degrees of knee rotation. This site needs JavaScript to work properly. 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. 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. Diagnosis requires careful assessment of radiographs of the knee and tibia (often missed injury). 2018 Apr;26(4):1104-1109. doi: 10.1007/s00167-017-4511-0. 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. PMID: 4837931.

Okubo A, Kajikawa Y, Nakajima S, Watanabe N, Yotsumoto T, Oshima Y, Iizawa N, Majima T. SICOT J. Warner B.T., Moulton S.G., Cram T.R., LaPrade R.F. Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. The common peroneal nerve (CPN) is visualized and protected throughout the case. To evaluate the treatment options, outcomes, and complications associated with proximal tibiofibular joint (PTFJ) instability, which will aim to improve surgical treatment of PTFJ instability and aid surgeons in their decision making and treatment selection. The integrity of the proximal tibiofibular joint is best visualized through plain radiographs. Proximal tibiofibular joint instability is a very unusual and uncommon condition. All nonsurgical therapies should be attempted before surgical intervention. Right Knee Surgery After Auto Bicycle Accident, Medical Second Opinion Service MRI/X-ray Review. Reconstructive procedures are recommended for patients whose source of pain is instability in the joint as opposed to arthritis. 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.4 The stability of the proximal tibiofibular joint is typically increased by full extension of the knee; if it is not, the lateral collateral ligament and posterolateral structures may also be injured. Injection of steroid and anesthetic into the joint can relieve pain and confirm a positive diagnosis. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. 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). Are you sure you want to trigger topic in your Anconeus AI algorithm? Instability of this joint may be in the anterolateral, posteromedial, or superior directions. Burke CJ, Grimm LJ, Boyle MJ, Moorman CT 3rd, Hash TW 2nd. Instability of the proximal tibiofibular joint (PTFJ) can present as frank dislocations, subtle symptoms of lateral knee pain, discomfort during activity, or symptoms related to irritation of the common peroneal nerve. Preoperative Considerations Eagan, MN 55121, I struggled with my knee for 18 months - having gone from 10,000 steps a day to only walking as needed. Accessibility Isolated traumatic instability of the proximal TFJ is an uncommon and underrecognized injury. 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. Axial (8A), coronal (8B), and sagittal (8C) fat-suppressed proton density-weighted images. 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 diagnosis is often unknown and delayed due to its variable and . Subluxation of the proximal tibiofibular joint. 1974 Jun;(101):192-7. 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. 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. The diagnosis of proximal tibiofibular joint instability is almost always based on a thorough clinical exam. The TightRope needle is then passed through to the anteromedial aspect of the tibia until it exits the skin medially. 1998 Feb;84(1):84-7. As the anterior arm of the long head of the biceps femoris tendon courses inferiorly, it contributes to the anterior aponeurosis and is intimately associated with the anterior tibiofibular ligament (green arrows). We anticipate that our patients will return back to full activities about 4-5 months after surgery, following the rehabilitation program. I can run, bike, & climb mountains. The fibular collateral ligament-biceps femoris bursa. 1997 Jul-Aug;25(4):439-43. doi: 10.1177/036354659702500404. Disclaimer. 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. Reconstruction for recurrent dislocation of the proximal tibiofibular joint. You can schedule an office consultation with Dr. LaPrade. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. AJR Am J Roentgenol. The first step in the management of chronic instability of the PTFJ is usually . 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. Novel ideas for the comprehensive evaluation of varus knee osteoarthritis: radiological measurements of the morphology of the lateral knee joint. In chronic injuries, the instability may appear obvious when the patient performs a maximal squat. I have looked many times for answers on my tibial tubercle osteotomy and never found any as detailed as i needed. 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). Medial Patellar Instability: A Systematic Review of the Literature of Outcomes After Surgical Treatment. 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. More commonly, however, AP and lateral radiographs are performed (Figure 4).

The integrity of the ankle and functional status of the peroneal nerve should also be assessed during the physical examination, because of the association of nerve, syndesmotic ligament, and interosseous membrane damage with this injury. History and physical examination are very important for diagnosis. Instability of this joint may be in the anterolateral, posteromedial, or superior directions. The integrity of the ankle and functional status of the peroneal nerve should also be assessed during the physical examination, because of the association of nerve, syndesmotic ligament, and interosseous membrane damage with this injury. This was devastating news after being a top triathlete (3rd in the world in my age group in 1989 & 1st nationally in my age group) and a big marathon runner. The coronal images demonstrate the normal anterior ligament located just caudal to the anterior arm of the short head of the biceps femoris tendon (purple arrow). Concurrent surgical treatment of posterolateral corner (PLC) and PTFJ instability poses technical challenges due to the limited working space . 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. Instability of the joint can be a result of an injury to these ligaments. 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. 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. Arthroscopy. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. Displacement of the fibular head in relation to the tibiavisible or palpable deformity. Epub 2005 Dec 22. The proximal fibula moves posteromedial with knee extension. 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. Results: Instability of the proximal tibiofibular joint . Oksum M, Randsborg PH. Level of evidence: Resecting and protecting the peroneal nerve during surgery can prevent peroneal nerve palsy. The treatment of proximal tibiofibular joint instability depends upon the time of presentation. Atraumatic instability is more common and often misdiagnosed. Bookshelf Instability of the proximal tibiofibular joint (PTFJ) may be acute or chronic in etiology and four types of instability initially described by Ogden include anterolateral dislocation, posteromedial dislocation, superior dislocation, and atraumatic subluxation.1Anterolateral dislocation is by far the most common form of instability and the focus of this discussion.

Proximal tibiofibular joint instability is a very unusual and uncommon condition. According to the Ogden classification, proximal tibiofibular joint injuries can be classified into the following subgroups 1-6: type 1: subluxation (more often in children and adolescents ) type 2: anterior dislocation (most common ~85%) type 3: posteromedial dislocation type 4: superior dislocation Radiographic features Plain radiograph Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. Knee Surgery, Sports Traumatology, Arthroscopy, 18(11), 1452-1455 . The drill is advanced through all 4 cortices. Knee Surg Sports Traumatol Arthrosc. Anatomy of the proximal tibiofibular joint. Conclusions: AJR Am J Roentgenol. Rev Chir Orthop Reparatrice Appar Mot. An official website of the United States government. 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. 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. 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.4 The stability of the proximal tibiofibular joint is typically increased by full extension of the knee; if it is not, the lateral collateral ligament and posterolateral structures may also be injured. Common considerations include lateral meniscus pathology, FCL injury/PLC instability, biceps tendonitis, and distal iliotibial band friction syndrome. PMID: 1749660. Inclusion criteria were as follows: PTFJ instability treatment techniques, PTFJ surgical outcomes, English language, and human studies. 3. 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. In cases of persistent instability, surgical treatment is indicated. The posterior ligament is disrupted near the fibular attachment on the axial image with subtle irregularity on the sagittal image. Clinical and Surgical Pearls However, this is a fairly common finding due to variable degrees of knee rotation. 2000 Mar-Apr;28(2):191-9. doi: 10.1177/03635465000280020901. The most common traumatic dislocations are in an anterolateral direction, followed by posteromedial and superior dislocations. The examination of patients with atraumatic subluxation or chronic instability should be performed with the knee flexed to 90 degrees. Edina, MN 55435, EAGAN-VIKING LAKES OFFICE 2008 Aug;191(2):W44-51. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. Instability of the proximal tibiofibular joint (PTFJ) can be post-traumatic or due to accumulative injuries and may also be underdiagnosed pathology that can present with symptoms of lateral and/or medial knee pain. 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). Ogden JA. Clinical Characteristics and Outcomes After Anatomic Reconstruction of the Proximal Tibiofibular Joint. Moatshe G, Cinque ME, Kruckeberg BM, Chahla J, LaPrade RF. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. With acute injury, patients usually complain of pain and a prominence in the lateral aspect of the knee. 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).
