Functional Recovery of the Donor Knee After Autologous Osteochondral Transplantation for Capitellar Osteochondritis Dissecans

Abstract

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 capitellar osteochondritis dissecans.

Osteochondritis dissecans of the elbow

“…All but one patient had an excellent result based on the Mayo elbow performance score. Furthermore, greater than half of the patients returned to previous levels of sport or higher [49]. Microfracture and retrograde drilling remain good options with consistent, reproducible results in shallow OCD lesions without lateral column involvement.…”

Osteochondral Autograft Transfer Technique for Glenoid Osteochondral Defect

“…In their case report, the patient was able to return to painless normal function, lacking only 20 of internal rotation at both 0 and 90 of abduction as compared with the opposite extremity. As stated previously, our preference is to harvest from the knee at the distal lateral trochlea just proximal to the sulcus terminalis using a mini-open approach, which has been shown to cause minimal morbidity 6 and is easily reproducible. Garretson et al 7 showed that the distal lateral trochlea has the lowest contact pressure among the lateral knee sites and is a desired location of autograft harvest.…”

“…Garretson et al 7 showed that the distal lateral trochlea has the lowest contact pressure among the lateral knee sites and is a desired location of autograft harvest. In a study by Nishimura et al, 6 12 patients underwent osteochondral autograft transport for severe osteochondritis dissecans of the humeral capitellum. Each patient received donor autograft plugs from the ipsilateral knee at the sulcus terminalis.…”

“…At 6 months postoperatively, all patients had re-established at least 80% of their preoperative extensor strength, and at 24 months, there were no radiographic signs of knee arthritis. 6 In addition, this mini-open harvest technique allows direct visualization of the harvest and offers finetuning of the approach angle to match the previously established a angle at the glenoid. The clinical outcomes at our institution are relatively short-term, but favorable results have been shown.…”

“…When the procedure is performed correctly, most patients have minimal longterm morbidity from donor harvest at the sulcus terminalis of the knee. 6,7 Step 2: Operative Setup…”
