High survival rate found with osteochondral allograft transplantation

BOSTON — Following osteochondral allograft transplantation, there was a high survival rate at an average of 5 years and arthroscopic debridement was the most common reoperation, according to results presented here.

“The take home points are that [there was] 86% survivorship and 39% reoperation rate at 5 years,” Brian J. Cole, MD, MBA, said in his presentation. “Arthroscopic debridement was most commonly performed and 82% of those that underwent debridement actually improved after the debridement, but 18% went on to failure.”

In a retrospective review of 171 patients who underwent osteochondral allograft transplantation, Cole and his colleagues collected radiographs and patient-reported outcomes.

Results showed 96% of patients had prior surgery, and there was an overall reoperation rate of 39% at an average of 2.5 years. Cole noted 32% of patients required additional reoperations, of which 59% occurred within the first 2 years of osteochondral allograft transplant. Results showed failure occurred in 16.8% of patients at an average of 5 years.
