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. Injuries to the joint are more commonly atraumatic and should be treated with surgery only after all other therapies have been exhausted. 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.1 Subluxation typically occurs in patients who have no history of inciting trauma but may have generalized ligamentous laxity; the condition is not commonly bilateral.

Communication between the proximal tibiofibular joint and knee via the subpopliteal recess: MR arthrography with histologic correlation and stratigraphic dissection. All nonsurgical therapies should be attempted before surgical intervention. Instability of the proximal tibiofibular joint . Preoperative Considerations Lateral Collateral Ligament and Proximal Tibiofibular Joint 31 year-old female status-post fall and twisting injury while skiing with lateral knee pain radiating down the calf. eCollection 2022 Sep. Pappa E, Kakridonis F, Trantos IA, Ioannidis K, Koundis G, Kokoroghiannis C. Cureus. I had wanted to do the Proximal Tibiofibular Surgery locally instead of flying out of state. MRI evaluation of recent injury will often reveal soft tissue edema both anterior and posterior to the joint, as well as within the ligaments. 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 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. Evaluation of the PTFJ on the lateral radiographs is less reliable due to variable degrees of knee rotation. EDINA- CROSSTOWN OFFICE Marchetti DC, Chahla J, Moatshe G, Slette EL, LaPrade RF.
