Revision Proximal Tibiofibular Joint Reconstruction for the Treatment of Chronic Instability Secondary to Suture Button Construct Failure

Recurrent proximal tibiofibular joint (PTFJ) instability can result from nonanatomic repair using a suture button construct. During initial reconstruction, proper identification of anatomic landmarks is critical for proper placement of suture button construct components and successful patient outcomes. In cases of symptomatic recurrent instability, a PTFJ reconstruction revision is warranted to alleviate symptoms of pain and instability. This Technical Note describes a technique for performing an anatomic PTFJ reconstruction revision and fibular collateral ligament reconstruction in which the semitendinosus is used as a graft for both the FCL and posterior ligamentous complex of the PTFJ. The biceps femoris is also repaired following a tear that resulted from a misplaced suture button.
