Summary
OCD lesion of the DLM with OCD group showed healings after meniscal surgery combination with surgical procedures for OCD. The incidence of postoperative OCD was significantly greater in DLM with OCD group compared with DLM group. The incidence of postoperative OCD was significantly greater for patients age less than 10 years old, and male sex, Lysholm score, Tegner activity scale.
Abstract
Purpose
This study aimed to evaluate the efficacy of surgery in a discoid lateral meniscus (DLM) with and without osteochondritis dissecans (OCD) of the lateral femoral condyle by clinical and radiological evaluations including magnetic resonance imaging (MRI).
Methods
During 2003–2017, 117 knees in 103 patients with a mean age of 12.7 years, 15 knees received arthroscopic meniscal surgery for DLM with OCD (DLM with OCD group) and 102 knees received arthroscopic meniscal surgery for isolated DLM (DLM group). The surgical procedures for DLM group were either saucerization, saucerization with repair or subtotal meniscectomy, depending on the type of DLM tear. The surgical procedures for DLM with OCD group were a combination with drilling, fixation or Autologous Osteochondral Transplantation (Mosaicplasty), depending on the type of OCD. Mean follow-up was 4.2 years. The clinical follow-up was evaluated using Lysholm score, Tegner activity scale, exercise frequency preoperatively and 1 year postoperatively.
Results
OCD lesion of the DLM with OCD group showed healings in 15 (100%) of 15 knees. Reoccurrence OCD was diagnosed in 4/15 (26.6%) knees in DLM with OCD group. Postoperative OCD was diagnosed in 7/102 (6.8%) knees in DLM group. The incidence of postoperative OCD was significantly greater for patients age less than 10 years old, and male sex, Tegner activity scale preinjury and after returning to sports, and exercise frequency per week.
Conclusion
OCD lesion of the DLM with OCD group showed healings in 15 (100%) of 15 knees. The incidence of postoperative OCD was significantly greater for patients age less than 10 years old, and male sex, low weight, Lysholm score, Tegner activity scale preinjury and after returning to sports, and exercise frequency per week on univariate analyses.
