Abstract Background:
For the treatment of osteochondral lesions of the talus (OCLTs), autologous matrix-induced chondrogenesis (AMIC)
is a safe 1-step procedure with good clinical and radiological results. However, data regarding postoperative sports activity after
AMIC are limited.

To identify significant factors influencing the rate of postoperative sports and recreational activities.

The sports and recreational activities of 60 patients (mean age, 34.9 +/- 11.5 years) undergoing the AMIC procedure
were retrospectively analyzed at a mean of 46.9 +/- 17.8 months (range, 24.5-87.0 months) postoperatively. The visual analog
scale (VAS) for pain score, Tegner activity scale score, activity rating scale (ARS) score, and satisfaction with surgery outcomes
were assessed.

Corrective calcaneal osteotomy was performed in 38 of 60 (63.3%) patients. Ligament repair was performed in 41 of 60
(68.3%) patients. The mean VAS score improved significantly from 6.9 +/- 1.6 points (range, 5-10 points) preoperatively to 2.3 +/-
1.9 points (range, 0-6 points) at latest follow-up (P\.001). No significant change in the mean Tegner activity scale score (3.3 +/-
2.0 preoperatively to 3.4 +/- 2.2 postoperatively; P = .526) and the mean ARS score (2.6 +/- 4.3 preoperatively to 2.3 +/- 3.4 postoperatively; P = .874) was noted. The percentage of patients involved in sports activity before the onset of symptoms became
significantly lower at the time of surgery (from 95.0% to 53.3%; P\ .001); no significant difference was noted postoperatively
(from 53.3% to 58.3%; P = .663). No significant difference of the weekly sports frequency and the duration of sports activity
was found postoperatively.

Patients undergoing AMIC repair of an OCLT participate at a similar low postoperative sports and recreational activity
level compared with the preoperative level.
