A Large Baker's Cyst Occurred after the Arthroscopic Meniscectomy. A Case Report

A 69 years old male presented with a large Baker's cyst in his left knee. He previously underwent the arthroscopic meniscectomy with a diagnosis of the medial meniscus injury of the left knee. Some authors have reported about the Baker's cyst occurred after the arthroscopic meniscorrhaphy, but, to our best knowledge, there is no report about the Baker's cyst occurred after the arthroscopic meniscectomy. This report describes the rare case about the Baker's cyst occurred after the arthroscopic meniscectomy and its process to the open surgery.
