{Abstract}: <B>OBJECTIVE: </B>To evaluate the efficacy of surgical treatment of the discoid lateral meniscus with osteochondritis dissecans (OCD) through clinical and radiological evaluations, focusing on recurrent or postoperative OCD occurrence.<BR><B>METHODS: </B>This retrospective study included patients with symptomatic discoid lateral meniscus with OCD (pre-OCD group) and without OCD (non-OCD group) who had undergone arthroscopic surgery with >5 years of follow-up. Age, sex, Lysholm score, Tegner activity scale, surgical procedure, and recurrent or postoperative OCD lesions were compared. The association between patient variables and postoperative OCD was determined using multivariate logistic regression analysis.<BR><B>RESULTS: </B>Of the 95 knees, 15 (15%) were in the pre-OCD group. Healing was observed in 14/15 (93%) knees. Recurrent and postoperative OCDs were reported in 4/15 (28.5%) knees in the pre-OCD and 7/80 (8.8%) knees in the non-OCD groups at a mean of 3.2 ± 1.1 and 3.7 ± 1.2 years, respectively. Pre- and postoperative Tegner activity scale and Lysholm scores were higher in the pre-OCD group but similar to those in the non-OCD group. The incidence of recurrent OCD in the pre-OCD group was significantly higher than that of postoperative OCD in the non-OCD group. Younger patients (odds ratio, 0.49; p = 0.003) had an increased risk of experiencing recurrent or postoperative OCD in multivariate analysis. The optimal cutoff age for distinguishing recurrent or postoperative OCD was 9 years.<BR><B>CONCLUSIONS: </B>Surgical procedures for OCD lesions in the pre-OCD group were successful. Multivariate analysis identified age as a risk factor for recurrent or postoperative OCD; therefore, conservative treatment is recommended for patients with discoid lateral meniscus before preadolescence to prevent postoperative OCD occurrence.<BR><B>METHODS: </B>Level III.
