Fig. 1

a Macroscopic view of femoral condyles 3 months after harvesting the medial meniscus showing early osteoarthritic changes: cartilage degeneration (asterisk) and osteophyte formation (arrow) on the medial side are detectable. Scale bar = 5 mm. b Histological image of the degenerated area of the femoral condyle showing early osteoarthritis changes. Scale bar = 2 mm. c Under higher magnification an OARSI grade 3 cartilage pathology with fissures extending into the deep zone can be observed. Scale bar = 0.2 mm. The average OARSI grading of all 12 knees at 3 months was 3.1
