Objective: Data regarding sport activity after autologous matrix-induced chondrogenesis (AMIC)-aided repair of osteochondral transplantation of the talus is limited. The aim of this study was to determine whether AMIC-aided osteochondral repair of the talus is a clinically successful treatment and enables patients to pursue regular and ongoing recreational sporting activities.

Method: Sixty patients were retrospectively analyzed to determine their sporting and recreational activities at an average of 30.7 months postoperatively (range, 12-70 months). The clinical evaluation included the visual analog scale (VAS) for pain, the Tegner activity scale, and the Activity Rating Scale (ARS).

Results ans conclusion: The VAS illustrated significant preoperative to postoperative improvements (6.8 to 3; P<.01). The Tegner score dropped from 3.2 preoperatively to 3.1 after surgery (P=.87), and the ARS decreased from 2.77 preoperatively to 1.60 postoperatively (P=.16). Regarding sporting activity, 95.3% of the patients were engaged in sports during their lifetimes compared with 51.2% the year before surgery and 55.8% at the time of survey. The duration of sports activities did not significantly change after surgery (P=.87). Of the 43 patients, 33% were very satisfied with the procedure, 51% were satisfied, and 16% were not satisfied.

Patients engage in fewer, less frequent sporting activities when a symptomatic osteochondral lesion (OCL) at the talus is present. AMIC-aided repair shows good clinical midterm results and allows patients to return to sporting activity. However, we found patients modify their postoperative sporting activities, and we noted a reduction of participation in high-impact and contact sports.
