This study was designed to describe the clinical and radiographical outcome of the HemiCAP(A (R)) resurfacing system as a salvage treatment for a failed index cartilage procedure. Fourteen patients were treated consecutively and clinically prospectively followed for a mean period of 26.1 +/- A 12.8 months. All patients were previously treated for their cartilage lesion. Radiographical data were analysed based on the Kellgren and Lawrence system. The patients involved in this study demonstrated a gradual clinical improvement in time. However, radiographically significant osteoarthritic changes were observed during the follow-up period. The position of the HemiCAP(A (R)) resurfacing system was adequate in all cases, and no signs of loosening were observed during the follow-up period. The HemiCAP(A (R)) resurfacing system is feasible as a salvage treatment for a failed index cartilage procedure and resulted in a gradual clinical improvement. However, the favourable clinical outcome was not confirmed by the radiographical findings.
