Medial Knee Endoscopy

Medial knee endoscopy can be utilized for management of cysts of the medial knee and repair and reconstruction of the medial patellofemoral ligament. Cysts of the medial knee vary in size. Surgery is indicated for symptomatic ones and surgical options include open resection, arthroscopic internal drainage, and endoscopic resection. Regardless the treatment choice of the cyst, the underlying intra-articular lesions should be addressed. Preoperative magnetic imaging is essential for preoperative planning not only to study the architecture of the cyst but also to detect any associated intra-articular pathology. This chapter describes the technique of endoscopic resection, which is indicated for large and multi-loculated cyst. Patellar lateral dislocation is a prevalent musculoskeletal disorder affecting young and middle-aged population. Medial patellofemoral ligament (MPFL) has been recognized the dominating soft tissue restraint for patella lateral displacement. MPFL repair and reconstruction is an effective and classical procedure for treatment of patellar lateral dislocation, with/without other corrective bony procedures. With the advancement of knee arthroscopy, endoscopically MPFL repair and reconstruction has been demonstrated to be a more accurate and effective procedure compared with the traditional method.
