This is a huge study for use proving cartilage transplant has success return to sport track record.

According to information presented at the AOSSM annual meeting, osteochondral allograft (OCA) transplantation may be a successful treatment option for highly active patients with a cartilage injury to the knee.

The research team reviewed data on 149 knees (142 patients) who participated in sport or recreational activity prior to cartilage injury and underwent OCA transplant. At mean 6-year follow-up, 76 percent of patients (113 of 149 knees) had returned to sport or recreational activity.

Of those, 28 percent returned to the same level of pre-injury sport, 48 percent partially returned, and 25 percent returned to a different sport or activity.

Of the 24 percent of patients who did not return to sport or activity, reasons included lifestyle events such as starting a family, changing careers, end of organized sports, knee-related issues, and concern about reinjury. Overall, 79 percent of knees were able to participate in a high level of activity and 71 percent reported having “very good” to “excellent” function.

 

The research team notes that 38 of 149 knees (26 percent) had further surgery following the OCA transplant, with the OCA treatment considered a failure in 14 knees (9 percent of entire cohort).

 

Patients who did not return to sport following OCA were more likely to be female, have injured their knee in an activity other than sports, and had a larger graft size.
