Early diagnosis of this injury can prevent further injuries to the joint that are harder to treat, such as chronic or fixed subluxation. Robert LaPrade, MD, PhD Same patient as radiographs in Figure 4. 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. Chronic instability is commonly the result of untreated or misdiagnosed subluxation of the PTFJ. Axial (7A) and coronal (7B) fat-suppressed proton density-weighted images demonstrate soft tissue edema at the PTFJ and a tear of the posterior ligament (blue arrows) near the fibular attachment. 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. Related PMID: 32061975. Proximal tibiofibular (PTF) joint instability is a rare condition: only 96 cases have been reported in the published literature. In general, we prefer an autograft (using ones own tissues) because it will heal in faster than an allograft (cadaver graft). Proximal Tibiofibular Joint Instability and Treatment - PubMed 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. PMID: 9240975. All nonsurgical therapies should be attempted before surgical intervention. Horst PK, LaPrade RF. Arthroscopy. Request Case Review or Office Consultation. The TightRope is subsequently tightened by pulling and spreading the sutures until the lateral button reaches the fibular head. Moatshe G, Cinque ME, Kruckeberg BM, Chahla J, LaPrade RF. I had wanted to do the Proximal Tibiofibular Surgery locally instead of flying out of state. Please enable it to take advantage of the complete set of features! Patients with subluxation of the proximal tibiofibular joint commonly report pain over the joint that is aggravated by direct pressure over the fibular head. An injury to the proximal tibiofibular joint is rather rare, but can be debilitating in patients who have symptoms. 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. 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). Traumatic dislocations of the proximal tibiofibular joint are uncommon and are normally caused by high-energy injury or a fall on a twisted knee. government site. Effects of a Partial Meniscectomy on Articular Cartilage, Femoral Condyle | Articular Cartilage Injury, FCL Injury or Lateral Collateral Ligament LCL Tear, Lateral Patellar Instability | MPFL Repair, Instability of the joint, especially during deep squatting, Concurrent irritation of the common peroneal nerve, because the common peroneal nerve crosses the lateral aspect of the fibular neck within 2-3 cm of the lateral aspect of the fibular head. Treatment of Instability of the Proximal Tibiofibular Joint by Dynamic Internal Fixation With a Suture Button. Conclusion: MRI is sensitive in the evaluation of tibiofibular ligamentous integrity in proximal tibiofibular instability. Treatment of Instability of the Proximal Tibiofibular Joint by Dynamic After 6 weeks postoperatively, patients may start to use a stationary bike with low resistance. (including injections and arthroscopic surgery), I heard Dr. La Prade was going to practice in the Twin Cities - where I live, & waited for him, based on his renown reputation. . 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. Instability of the proximal tibiofibular joint occurs when the ligaments which provide stability to this joint are injured. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. 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 diagnosis of joint instability can be confirmed by steroid and local anesthetic injection into the joint under fluoroscopic guidance, if pain is relieved. 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. 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 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. eCollection 2022 Jun. 2016 May-Jun;40(3):470-6. doi: 10.1016/j.clinimag.2015.12.011. Proximal tibiofibular joint (PTFJ) instability is a rare knee injury, accounting for less than 1% of knee injuries. We have found it to be very effective at restoring stability to this joint and not resulting in joint overconstraint. PDF Proximal Tibiofibular Joint (PTFJ): Stabilizing Tape Technique for A more definitive way to validate a diagnosis of proximal tibiofibular joint instability is with a taping program of the joint. The treatment of proximal tibiofibular joint instability usually depends upon whether it is an acute or chronic injury. 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. Most patients are cleared to begin full activities between four to six months postoperatively, assuming they have adequate restoration of proximal tibiofibular joint stability, pain relief, and return of strength, agility and endurance. The diagnosis of joint instability can be confirmed by steroid and local anesthetic injection into the joint under fluoroscopic guidance, if pain is relieved. Kobbe P., Flohe S., Wellmann M., Russe K. Stabilization of chronic proximal tibiofibular joint instability with a semitendinosus graft. We anticipate that our patients will return back to full activities about 4-5 months after surgery, following the rehabilitation program. Epub 2017 Mar 21. Anavian J, Marchetti DC, Moatshe G, Slette EL, Chahla J, Brady AW, Civitarese DM, LaPrade RF. 1991 Nov;20(11):957-60. 1998 Feb;84(1):84-7. 3. 1 The post-traumatic etiology is most frequently reported as that the initial trauma may be unnoticed and therefore absent in the clinical history. A prospective study of normal knees and knees with surgically verified grade III injuries. Proximal Tibiofibular Joint (PTFJ):Stabilizing Tape Technique for Posterior Instability Learn How We Can Help You Stay Active Request a Consultation About the Author: Robert LaPrade, MD Robert LaPrade, MD, PhD has specialized skills and expertise in diagnosing and treating complicated knee injuries. Patients with subluxation of the proximal tibiofibular joint commonly report pain over the joint that is aggravated by direct pressure over the fibular head. I could not bear weight on my right side though I tried repeatedly, but finally I went and got an MRI and one of the orthopedic surgeons that I worked with was shocked when he saw the MRI result. We advise that patients initiate a program of weaning off the crutches at the six week point and starting the use of a stationary bike to regain the strength of their quadriceps mechanism. Internal bracing is performed with a knotless suture button (TightRope syndesmosis implant; Arthrex). Epub 2017 Mar 24. Proximal tibiofibular ligament reconstruction, specifically biceps rerouting and anatomic graft reconstruction, leads to improved outcomes with low complication rates. The .gov means its official. Shapiro G.S., Fanton G.S., Dillingham M.F. The proximal tibiofibular joint ligaments both strengthen the joint and allow it to rotate and translate during ankle and knee motion. All nonsurgical therapies should be attempted before surgical intervention. Bookshelf On the AP radiograph, the fibula should overlap the lateral margin of the lateral tibial condyle and lateral displacement will widen the interosseous space. However, in chronic cases, immobilization would not be sufficient to achieve this goal. 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. 4010 W. 65th St. The condition is often missed, and the true incidence is unknown. Journal of the American Academy of Orthopaedic Surgeons &NA; Injury to the proximal tibiofibular joint is typically seen in athletes whose sports require violent twisting motions of the flexed knee. 1997 Jul-Aug;25(4):439-43. doi: 10.1177/036354659702500404. 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). 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). However, in chronic cases, immobilization would not be sufficient to achieve this goal. Epub 2017 May 10. Epub 2010 Feb 3. 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. Atraumatic proximal tibiofibular joint subluxation is the more common presentation of proximal tibiofibular joint instability. 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 reconstructive procedure is recommended for patients whose pain is a result of joint instability. Proximal Tibiofibular Joint Reconstruction With a Semitendinosus Allograft for Chronic Instability. Knee Surg Sports Traumatol Arthrosc. 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. Treatment for proximal tibiofibular joint stability requires that nonsurgical management be attempted first for patients with atraumatic subluxation of the proximal tibiofibular joint. Sep 11, 2016 | Posted by admin in SPORT MEDICINE | Comments Off on Management of Proximal Tibiofibular Instability. Atraumatic instability is more common and often misdiagnosed. 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. 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. 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). 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). 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. Proximal Tibiofibular Joint Arthritis Co-existing With a Medial Meniscal Tear: A Case Report. 2020 Jun;36(6):1649-1654. doi: 10.1016/j.arthro.2020.01.056. Most commonly, hamstring allografts and autografts are used to reconstruct the proximal tibiofibular joint anatomically. Chapter Synopsis Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. Instability of the joint can be a result of an injury to these ligaments. Numerous disorders of the proximal tibiofibular joint can present as lateral knee pain. Instability of the joint can be a result of an injury to these ligaments. 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. Evaluation of the joint, the supporting ligaments, and the common peroneal nerve should be assessed alongside evaluation of the posterolateral corner. History of Traumatic Injury 2010 Sep;19(5):409-14. doi: 10.1097/BPB.0b013e3283395f6f. Am J Sports Med. 2006 Mar;14(3):241-9. doi: 10.1007/s00167-005-0684-z. 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. 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. Conclusion: The ligaments of the human proximal tibiofibular joint were able to withstand a mean ultimate failure load of 517 144 N for the anterior complex and 322 160 N for the posterior complex. Reconstruction is recommended to maintain correct anatomic function and rotation of the joint. 8600 Rockville Pike 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.
