Abstract
-
PURPOSE: To evaluate the clinical results of arthroscopic inside-out repair leaving posterior horn tear.
MATERIALS AND METHODS
Among the patients taken arthroscopic meniscal repair due to meniscus longitudinal tear from Jan. 1999 to Dec. 2004, total 32 patients were evaluated, and followed at minimum of two years(mean 32 months). Meniscal repair was done as maximum 3mm interval. The length of unrepaired posterior horn was mean 7.5mm.
RESULTS
Preoperative Lysholm score was mean 62.5 and postoperative improved to 91.0. Twenty eight cases(87.5%) showed excellent or good results by Tapper and Hoover criteria. In 4 cases, symptoms recurred at 4 to 12 months after repair and 2 cases were combined with ACL deficiency. Second look arthroscopy was performed in 10 cases, 4 cases for recurred symptom and 6 cases for determining whether healing of untreated posterior horn occurred or not. We observed complete healing of 4 cases and incomplete healing of 2 cases on the acquisition of stability.
CONCLUSION
It was suggested that meniscal repair leaving posterior horn tear may be healed if both stabilities of the torn area and the knee joint were maintained.
