[Hamstring tendon transplantation embedding reconstruction of medial patellofemoral ligament for the treatment of recurrent patellar dislocation].
OBJECTIVE
To explore the effectiveness of hamstring tendon graft embedding reconstruction of medial patellofemoral ligament for the treatment of recurrent dislocation of the patella.


METHODS
From March 2008 to June 2013,67 patients with recurrent dislocation of patella were treated, including 28 males, 39 females with an average age of 22 years ranging from 10 to 42 years old. The clinical manifestations involved knee joint instability,"giving way", sense of patellar dislocation, anterior knee pain. All 67 patients underwent arthroscopic hamstring tendon graft embedding reconstruction of the medial patellofemoral ligament. The curative effect were evaluated by preoperative and postoperative Lysholm score and Q angle changes.


RESULTS
All cases were followed up after operation and the mean follow-up time was(27.5±13.4) months(4 to 69 months). Postoperative incision were healed well and no patellar dislocation or subluxation occurred. Lysholm score improved from preoperative 76.35±2.86 to 82.71±2.29 postoperatively; Q angle decreased from preoperative (18.75±2.33)° to postoperative(13.28±1.75)°.


CONCLUSIONS
The method for the reconstruction of medial patellofemoral ligament can provide enough tension, patellar stability.imoroving the function of knee ioint.
