Arthroscopic suture anchor repair for lateral patellar instability

Abstract

Several all-arthroscopic techniques have been described to address patellar instability. Most arthroscopic procedures focus on soft tissue plication or "tightening" of the medial retinacular structures to correct lateral patellar instability. We found these techniques to be ineffective when the medial stabilizers were avulsed from the patella. As a result, we have developed an arthroscopic technique to repair medial patellofemoral ligament avulsions to the patella using suture anchors.
