Chondral Resurfacing of Articular Cartilage Defects in the Knee with the Microfracture Technique

Articular cartilage lesions are diagnosed with increasing frequency and are often associated with substantial morbidity and functional limitation1,2. Because of its minimal invasiveness, technical ease, lim- ited surgical morbidity, and high cost-effectiveness, microfracture re- pair is a frequently used first-line treatment option for full-thickness articular cartilage defects in the knee and is increasingly applied to other joints3. Clinical data have indicated that the clinical outcome after microfracture is associated with better repair cartilage filling and that patients with poor-quality filling have limited functional improvement4. The use of a systematic surgical approach with attention to subtle technical details can help to optimize cartilage repair after microfracture, thereby optimizing clinical outcome.
