Forty five patients with knee problems attending the out patient clinics of the Central Institute of Orthopaedics, Safdarjang Hospital, New Delhi, with suspected internal derangements between August 93 - July 94 were subjected to an arthroscopic examination in order to confirm/alter the diagnosis and simultaneously correct the pathology detected. Mal-aligned knees were excluded from this study as no therapeutic benefit was expected. The superiority of an arthroscopic diagnosis and its attendant advantages were proved beyond doubt. However, certain problems of the knee can be detected equally well clinically.
