Arthroscopic chondrectomy as a treatment of cartilage lesions

Although favorable effects of debridement with chondrectomy and drilling or abrasion have been reported in treating of cartilage lesions in the knee joint; however, in most cases an additional intervention is generally performed during arthroscopy. We studied 53 consecutive patients with solitary chondral lesions in the weight-bearing part of the knee and treated 86 cartilage lesions by arthroscopic debridement, including a detailed removal of damaged or undermined cartilage. We evaluated the postoperative course by questionnaire (mean follow-up 6.5 years, response rate 83%). All patients reported a positive effect of chondrectomy: 69% considered the knee considerably better or cured and 77% regarded the effect as permanent. There was no complication of the arthroscopies performed, and no patient noted any deterioration in the condition. We therefore recommend routine chondrectomy of cartilage lesions when these are found during an arthroscopy.
