Reconstruction of the Medial Patellofemoral Ligament
نویسندگان
چکیده
Patellar instability has been shown to be associated with different major factors. However, studies have demonstrated that soft tissue reconstructions are adequate enough to reestablish patellar constraint. In recent years, the medial patellofemoral ligament has been recognized as the primary passive restraint for lateral translation of the patella. Their reconstruction has gain popularity as the procedure is quite simple and fast. Although several surgical techniques have been described for their reconstruction, no clear consensus has been reached as to which is best. We present an implant-free, medial patellofemoral ligament reconstruction technique that uses a gracilis tendon autograft, 2 bone convergent tunnels at the original patellar attachment, and looping the graft around the adductor magnus tendon that is used as a pulley for femoral fixation.

The medial patellofemoral ligament has been recognized as the structure primarily responsible for preventing patellar subluxation or dislocation.1-3 Anatomic dissection studies identified the medial patellofemoral ligament as a band of tissue connecting the femoral medial epicondyle to the proximal part of the medial edge of the patella (Figure 1).1-6 Imaging studies7-11 and surgical exploratio...

Medial patellofemoral instability is a rare, disabling condition that is often associated with the wrong indication for lateral retinacular release or overcorrection with medializing tibial tubercle osteotomy. It is an even less common complication after total knee arthroplasty (TKA). The lateral patellofemoral ligament is an important lateral stabilizer of the patella against medial subluxatio...

Patellofemoral dislocations are common. In cases with recurrence or residual instability, surgical intervention is usually considered. Numerous treatment protocols have been used in the past to treat patellofemoral instability secondary to patella dislocation. Reconstruction of the medial patellofemoral ligament is one of the possible options, since it was acknowledged to have a major medial st...

The standard surgical approach for chronic lateral patellar instability with at least two documented patellar dislocations is to stabilize the patella by using an anatomic medial patellofemoral ligament reconstruction with a mini-open technique and a graft that is stronger than the native ligament to compensate for the uncorrected predisposing factors underlying patellar instability. Even thoug...
