[Treatment of instability of patellofemoral joint through athroscopic repair of medial patellofemoral ligament for adolescents with epiphyseal non-closure by allogenic tendon].
OBJECTIVE
To explore the efficacy of arthroscopic repair of medial patellofemoral ligament (MPFL) for adolescents with epiphyseal non-closure by allogenic tendon in the treatment of instable patellofemoral joint.


METHODS
There were a total of 38 cases including 61 knees with patellofemoral instability from June 2008 to January 2010 at our department. They were diagnosed according to the history of illness, apprehension test and tangential position radiograph in patellofemoral joint.


RESULTS
A total of 33 patients with 52 knees were followed up for an average of 12 months (range: 8 - 19). All apprehension tests were negative. No recurrent displacement was found. The pre-operative Lysholm score of 75.5 ± 4.7 increased to 91.1 ± 5.7. There was significant difference.


CONCLUSIONS
Arthroscope-assisted allograft reconstruction of medial patellofemoral ligament tendon is both mini-invasive and reliable for the treatment of epiphyseal non-closure adolescents with traumatic patellofemoral instability.
