Patient-oriented and performance-based outcomes after knee autologous chondrocyte implantation: a timeline for the first year of recovery.

摘要

Patients' perceptions of improvements may outpace physical changes in function. Decreased function for at least the first 3 mo after ACI should be anticipated, and improvement in performance of tasks requiring weight-bearing knee flexion, such as squatting, going down stairs, or lunging, may not occur for a year or more after surgery.
