BACKGROUND: Osteochondral autograft transplantation has been advocated to treat severe @entity4713 dissecans of the humeral capitellum in throwing athletes to reproduce the normal hyaline cartilage and achieve long-term elbow function. Although some authors have reported good outcomes, the current authors are concerned about functional recovery of the donor knee after osteochondral grafts have been harvested. PURPOSE: The present prospective study analyzed functional recovery of the donor knee after osteochondral graft harvest. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Twelve male @entity1 (average age at surgery, 14.4 years) had severe @entity4713 dissecans of the humeral capitellum treated with osteochondral autograft transplantation from the contralateral knee joint. The donor knee of each @entity1 was assessed for @entity158 (visual analog scale), joint effusion, Lysholm score, radiographic findings, and muscle strength (60 and 180 deg/sec). RESULTS: At 3 months after surgery, 10 @entity1 were @entity158 -free (visual analog scale score, 0); none had @entity1143 ; and 10 gained 100 points in the Lysholm score. However, muscle power (60 deg/sec) of the knee extensor revealed 8 @entity1 with reduced muscle strength at 3 months compared with the preoperative level, although 11 @entity1 reached preoperative knee extensor muscle strength at 12 months. Radiographic findings at 24 months showed that none of the @entity1 had @entity626 . CONCLUSION: A time lag was evident in recovery between postoperative symptoms and muscle power at 3 months. However, harvesting osteochondral grafts did not exert adverse effects on donor knee function in young athletes at 2 years after undergoing osteochondral autograft transplantation for @entity1843 .
