OBJECTIVE: To evaluate an improving operative procedure and the clinical results of arthroscopically assisted treatment for @entity8043 . METHODS: Between April 2006 and March 2009, 22 @entity1 (25 knees) with primary @entity697 underwent an improving arthroscopic operation, release of lateral retinaculum and suture of medial capsule and retinaculum structure. There were 5 males and 17 females with an average age of 23.6 years (range, 14-34 years). Three @entity1 had bilateral procedure. Eleven left knees and 14 right knees were involved. The disease duration was 1-10 days with an average of 5.9 days. All @entity1 had @entity3029 ; of them, 14 @entity1 showed reduction without treatment, and 8 @entity1 showed dislocation at admission and were given close manipulative reduction. The results were positive for apprehension test in all @entity1 with the limitation of passive motion and for Ballottable Patella Sign in 15 cases. Lysholm score, visual analogue scale (VAS) score, and Insall scale were adopted to evaluate the effect. RESULTS: All incisions healed by first intention. All the @entity1 were followed up 12-36 months (17 months on average). During the first 3 months after operation, sunken skin in the puncture point medial to the patella was observed in 12 knees; 10 knees @entity158 of the soft tissue lateral to the patella; 15 knees felt tense in the soft tissue medial to the patella, however, all these problems disappeared or recovered gradually after rehabilitation and conservative treatment. No recurrence of dislocation was observed during the follow-up. Lysholm score was significantly improved from preoperative 67.3 +/- 5.7 to postoperative 96.6 +/- 4.5 (t = 3.241, P = 0.003) and VAS score from 6.5 +/- 0.5 to 1.8 +/- 0.4 (t = 2.154, P = 0.040). According to Insall scale, the results were excellent in 18 knees, good in 5 knees, and fair in 2 knees at 1 year after operation with an excellent and good rate of 92%. CONCLUSION: The improving procedure of arthroscopically assisted treatment for @entity8043 is a minimally invasive operation and has a number of benefits. Its short-term clinical outcome was satisfactory.
