Reading about microfracture for focal cartilage defects of the hip, we ponder whether the hip resembles the knee with regard to focal cartilage defects. Minimally invasive microfracture has been a first-line therapy for focal cartilage defects. Microfracture results in fibrous cartilage and unpredictable repair volume, which could be better than absent cartilage, particularly if knee symptoms abate. However, of late, microfracture is not recommended because destruction of subchondral anatomy may result in subchondral cyst formation.
