Fresh Osteochondral Allograft in a Complex Hoffa Fracture - Case Report

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Regenerative Medicine

Background:

• Hoffa fracture (HF) involves the posterior femoral condyle, with an incidence of 0.65% in femoral fractures.
• Typically occurs in high-energy trauma with the knee flexed over 90°.
• Complex medial HF with knee dislocation is rare.

Purpose of the Study:

• To report a case of complex medial Hoffa fracture with knee dislocation.
• To evaluate the efficacy of osteochondral allograft transplantation for complex HF.
• To assess long-term outcomes in preventing post-traumatic osteoarthrosis.

Main Methods:

• A case report of a patient with complex medial Hoffa fracture and knee dislocation.
• Treatment involved osteochondral allograft transplantation.
• Radiologic analysis at two-year follow-up.

Main Results:

• Complete bone healing and successful allograft integration were observed at two years.
• The patient experienced no signs of early post-traumatic osteoarthrosis.
• Restoration of joint surface anatomy was achieved.

Conclusions:

• Osteochondral allograft transplantation is a viable option for complex Hoffa fractures.
• This approach can restore joint anatomy and prevent early osteoarthrosis in young patients.
• Early intervention with allografts may improve long-term knee function.
