Osteochondral Autograft Transfer for Capitellar Chondral and Osteochondral Defects

Area of Science:

• Orthopedic surgery
• Sports medicine
• Regenerative medicine

Background:

• Chondral and osteochondral lesions of the humeral capitellum are common in adolescent athletes, particularly baseball players and gymnasts.
• Osteochondritis dissecans is a notable condition affecting this joint.
• Current surgical options exist, but outcomes vary.

Purpose of the Study:

• To describe the technique of osteochondral autograft transfer from the contralateral knee for humeral capitellum lesions.
• To evaluate the efficacy of this procedure in facilitating return to sport and minimizing donor-site morbidity.

Main Methods:

• Osteochondral autograft transfer using tissue from the contralateral knee.
• Management of the donor site with osteochondral allograft backfill.
• Detailed description of the surgical procedure and its technical aspects.

Main Results:

• The described surgical procedure is technically demanding yet highly reproducible.
• This technique maximizes the potential for patients to return to play.
• Donor-site morbidity is minimized with this approach.

Conclusions:

• Osteochondral autograft transfer from the knee is a viable and effective surgical option for humeral capitellum chondral lesions.
• The procedure offers superior rates of return to sport compared to other techniques.
• This method balances efficacy in treating the capitellum lesion with preservation of the donor site.
