Arthroscopic Meniscectomy and Meniscoplasty for a Torn Discoid Medial Meniscus: Case Report, Surgical Technique, and Literature Review

Gokhale Nikhil Abhay et al. J Orthop Case Rep. 2016 Sep-Oct.

Abstract

Introduction: Normal menisci of the knee are semilunar structures. Sometimes, a meniscus may be found to be thickened and disc like and is called a discoid meniscus. Such a discoid variant is usually found in the lateral meniscus. Its occurrence in the medial meniscus is extremely rare.

Case report: We report a case of an 18-year-old female, who presented to us with knee pain and was found to have a discoid medial meniscus with a tear. We operated on her arthroscopically and performed meniscectomy and meniscoplasty. Postoperatively, the patient was free of her knee pain.

Conclusion: Discoid medial meniscus is a rare phenomenon which can present as a cause of knee pain. If discoid meniscus is symptomatic, the management includes arthroscopic meniscectomy and meniscoplasty.

Keywords: Meniscoplasty; arthroscopic meniscectomy; discoid medial meniscus.
