Results of isolated meniscal repair evaluated by second-look arthroscopy.

Thirty-six isolated torn menisci in 35 patients (average age, 24 years) which had been repaired arthroscopically using an inside-out technique were evaluated by second-look arthroscopy. The time from meniscal repair to second-look arthroscopy ranged from 2 to 10 months with a mean of 5 months. The indications for meniscal repair were a longitudinal or oblique tear located at the outer half of the meniscus. Twenty (56%) were graded as excellent, 10 (28%) as good, and 6 (16%) were graded as poor. Neither age nor length of time between injury and repair affected meniscal healing. The medial meniscal repairs showed better results than the lateral repairs (rate of excellent results: medial, 82%; lateral, 44%; P < .01, chi-squared test). The rate of excellent results for those with normal meniscal bodies at the time of repair was 79%, which was significantly higher than that seen in the cases with deformed and/or superficial damage to the meniscal body (36%; P < .05, chi-squared test).
