Meniscectomy: arthrotomy versus arthroscopy

Abstract

The arthroscope has changed the orthopaedist's ap proach to evaluation of knee injuries. Diagnostic ar throscopy is now well-accepted and has led to oper ative arthroscopy. The advantages and contraindica tions of operative arthroscopy are reviewed in this report. The physiologic role of the meniscus is dis cussed, stressing the importance of leaving normal tissue. Necessary equipment and cost of each of three advancing stages of arthroscopic surgery capability are discussed. A study group of 68 simple meniscec tomy patients is presented: 34 treated by traditional arthrotomy and meniscectomy, and 34 by arthro scopic meniscectomy. Parameters assessed included: nights in hospital, postoperative swelling, achieve ment of 120° flexion, days on crutches, return to full activity, work, and sports. Operating room and total hospital costs are reviewed. Arthroscopic meniscec tomy produced earlier complete rehabilitation and at less cost in this series.
