Abstract:
BACKGROUND:Autologous hamstring tendon reconstruction of the medial patel ofemoral ligament is now more popular surgical procedure.
OBJECTIVE:To study the clinical mid-term outcomes of isolated medial patel ofemoral ligament reconstruction for recurrent lateral patel ar dislocation.
METHODS:The clinical data of 24 patients (25 knees) undergoing medial patel ofemoral ligament reconstruction for recurrent patel ar dislocation from September 2006 to September 2009 were retrospectively studied. Clinical, functional, and CT outcomes were assessed at an average of 3.1 years after surgery (range, 2-5 years), using recurrent instability as the primary end point.
RESULTS AND CONCLUSION:The success rate of medial patel ofemoral ligament reconstruction for preventing recurrent dislocations was 92%. Two patients (8%) experienced a recurrent lateral patel ar dislocation, and required a reoperation. At final fol ow-up, the mean IKDC, Tenger and Lycholm scores were significantly higher than those before operation (P<0.01). Reconstruction of the medial patel ofemoral ligament for recurrent patel ar instability is a minimal y invasive operation and has a number of benefits. The mid-term clinical outcome was satisfactory.
