Abstract:
PURPOSE: To assess the efficacy of arthroscopic decompression of the meniscal cyst. MATERIAL AND METHOD: From January 1996 to December 1997, 8 patients with meniscal cyst were treated by arthroscopic cyst decompression as well as partial meniscectomy of torn menisci. The average follow-up was 18.8 months(range: 12~35 months). There were 6 men and 2 women and the average age was 38.1 years(range: 26 to 56 years). Six(75%) patients had no history of trauma associated with their symptoms. All the meniscal cysts were associated with horizontal tear of the menisci. The arthroscopic partial meniscectomy consisted of gentle trimming of leading edge of the superior leaf and excision out to peripheral rim of the inferior leaf, followed by intraarticular cyst decompression using probe, punch for-ceps or shaver with pressure over the cyst. Postoperative results were assessed according to the evaluation form of Glasgow et al. RESULT: The ratio of medial-to-lateral cyst formation was 1:1. Meniscal cysts were always associated with horizontal tears of the meniscus. The patterns of horizontal tear consisted of 2 horizontal/cleav-age(25%), 2 horizontal/flap(25%), and 4 horizontal/ degenerative complex tears(50%). The sites of meniscal tears were the posterior horn-midbody junction of the medial meniscus in 4, the anterior horn-midbody junction of the lateral meniscus in 3 and the midbody of the lateral meniscus in 1. We could get excellent or good results in all the patients with no recurrence of the cyst. CONCLUSIONS: The treatment of the meniscal cyst can be entirely arthroscopic(partial meniscectomy and intraarticular decompression of the cyst) with predictable success.
