Schematic drawing demonstrating the typical presentation of an articular cartilage lesion upon primary arthroscopic inspection.







Schematic drawing illustrating the range of motion during which the cartilage defect articulates with the opposing joint surface.

Photograph showing arthroscopic awl tips with conical shape angulations of 30°, 45°, and 90°.







Drawing illustrating the technique for microfracture of patellar lesions.















Sagittal fast-spin-echo magnetic resonance image of the knee showing a high-grade lesion (arrows) of the medial femoral condyle before (Fig. 12-A) and after cartilage repair with

microfracture chondroplasty (Fig. 12-B).
