Recently, medial patellofemoral ligament reconstruction has gained popularity as a treatment modality for recurrent patellar instability.2-6 Patients who have failed surgical interventions including lateral release, medial patellofemoral ligament reefing, and distal realignment may be good candidates for medial patellofemoral ligament reconstruction. The anatomy and biomechanics of the medial p...

recurrent dislocation of patella may occur in patients with ligament laxity. method of treatment in this condition is controversial but patellofemoral ligament reconstruction is the most accepted method. we present a patient with rubinstein-taybi syndrome and recurrent patellar dislocation who managed successfully by patellofemoral ligament reconstruction.

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...

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...

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...

Recurrent dislocation of patella may occur in patients with ligament laxity. Method of treatment in this condition is controversial but patellofemoral ligament reconstruction is the most accepted method. We present a patient with Rubinstein-Taybi syndrome and recurrent patellar dislocation who managed successfully by patellofemoral ligament reconstruction.

BACKGROUND Primary patellofemoral dislocations are common. In most patients, non-operative management produces satisfactory outcome. If the dislocation recurs after a trial of rehabilitation, operative intervention is considered, with the aim of restoring the soft tissue anatomy to normal. Ninety four percent of patients suffer a tear to the medial patellofemoral ligament (MPFL) following a pat...

The medial soft-tissue restraints of the patella, specifically the medial patellofemoral ligament and the vastus medialis obliquus muscle, are critical to patellofemoral joint stability. A reliable and inexpensive imaging technique would be clinically useful especially after acute patellar dislocation. The medial patellofemoral ligament and the vastus medialis obliquus muscle were identified in...

To the Editor: I read with interest the paper by Sillanpàà et al. [1] entitled ‘‘Ligament Reconstruction Versus Distal Realignment for Patellar Dislocation’’ published in the June 2008 issue. I congratulate the authors on their study, for the longterm followup and for the comparative study with distal realignment. However, I ask for clarification of two issues. First, what are the indications f...
