Two cases with microfracture of the medial tibial condyle were reported. The fracture was supposed to be a stress fracture. Gonalgia reduced by using a pair of cruthes in several weeks. Differential diagnosis from pes anserinus bursitis and aseptic necrosis of femoral condyle was important because of a lack of the X-ray signs in a initial stage.
