Retained posterior horn of the medial meniscus.
The incidence of a symptomatic retained posterior fragment of the medial meniscus in 2 different groups of patients with medial meniscectomy is compared. If the original surgery was done through one capsular incision, there was a 9.5% incidence of symptomatic retained posterior fragment as compared to 0.2% incidence if the original surgery was performed through 2 capsular incisions. For total excision of the meniscus medial meniscectomy should be performed through 2 capsular incisions.
