The incidence of prepatellar neuropathy following medial meniscectomy.

The frequency of lasting prepatellar dysesthesia following medial meniscectomy has been under-estimated. Analysis of 87 patients undergoing medial meniscectomy in a prospective study with a minimum follow-up period of six months showed dysesthesia in 63.2% immediately after operation. The condition persisted in 44.4% at six months. Female patients had a higher incidence of dysesthesia than male patients and had a slower recovery rate. Numbness had a less favorable prognosis than paresthesia.
