OBJECTIVE: To introduce an arthroscopic technique in managing recurrent @entity12351 and its clinical results. METHODS: Sixteen @entity1 with recurrent @entity8043 were reviewed, including 3 males and 13 females. The average age was 17.6 years old (ranged from 14 to 32 years). The @entity1 suffering from patellar sub-luxation averaged 18.5 months (ranged from 6 to 23 months)before operation. These @entity1 were treated with lateral patellar retinacular release outside the synovial bursa of knee joint and medial patellofemoral ligament reconstruction using the semitendinosus tendon free autograft. The Lyshohm scores before and after operation were used to evaluate outcomes at the final follow-up. RESULTS: All the @entity1 were followed up, and the duration ranged from 6 to 48 months, with an average of 12 months. There was no recurrence. The Q angle decreased from (16.4    3.7)   to (10.1    1.4)  ; insall index decreased from 1.37    0.25 to 1.28    0.23; congruence angle decreased from (21.3    2.6)   to (5.86    2.23)  ; Lysholm score improved from 76.1    5.2 to 89.8    4.1 at 6 months after operation. CONCLUSION: Compared with conventional procedure, arthroscopic surgery for recurrent @entity12351 achieves excellent outcomes with minimum invasion.
