Short-term functional outcomes of symptomatic discoid lateral meniscus after arthroscopic partial meniscectomy and saucerization

A discoid meniscus is a congenital dysplastic meniscus in which atypical development of the meniscus lead to a broad disc like configuration. The lateral discoid meniscus is more common than the medial. It is larger, wider and thicker than the normal fibro-cartilaginous meniscus of the knee and covers the tibial plateau more than the normal one. The aim is to investigate the short-term clinical functional outcomes of arthroscopic partial meniscectomy and saucerization for the treatment of symptomatic discoid lateral meniscus. An interventional study on 10 patients who underwent arthroscopic partial menisectomy and saucerization for symptomatic discoid lateral meniscus. The patient’s age was ranging from 9 - 52 years with a mean±SD of 33.6± 11.11 years, and the mean follow-up period was 12 months. The mean of Lysholm Knee Scoring Scale was significantly increased after three and after nine months compared to the scale before management (61.9% versus 80.4%, P= 0.001; and 61.9% versus 93.1%, P=0.001, respectively). Arthroscopic partial menisectomy & saucerization for symptomatic discoid lateral meniscus led to satisfactory clinical outcomes after short term follow up 12 months. The (age, sex, occupation, and type of DLM according to Watanabe classification) have no effect on the result of operation which mean the orthopedics handling and surgical facility determine the outcome of treatment.
