Focal full thickness articular cartilage lesions treated with an articular resurfacing prosthesis in the middle-aged
INTRODUCTION: Localised full thickness articular defects of the knee are common and disabling in the middle-aged. There are numerous treatment options for articular defects, the results of which are unpredictable in this age group. The purpose of this study was to evaluate a focal articular resurfacing prosthesis used in the treatment of these defects. METHODS: A consecutive series of patients treated between 2005 and 2010 with a HemiCAP® resurfacing procedure were retrospectively reviewed. Follow-up scores of the KOOS, IKDC, SF-36 and patient satisfaction were obtained. Radiographic evaluation was also obtained. RESULTS: Twenty-two patients met the inclusion criteria. Nineteen patients were followed-up 4.7 ± 5.9 years after surgery. Three patients had revision surgery and were not followed up. The patients were 44.7 ± 5.9 years old. The follow-up KOOS scores demonstrated comparable scores on the pain and activities of daily living sub-scales when compared to normative data; however, the sports (P<0.001) and quality of life (P=0.001) sub-scales scores were lower in the HemiCAP® patients when compared to normative data. Only the physical functioning sub-scale score of the SF-36, and not the other seven sub-scale scores, was lower (P=0.016) in the HemiCAP® patients when compared to normative data. General patient satisfaction revealed that 79% considered their result as very good or excellent. CONCLUSION: HemiCAP® articular resurfacing is an effective treatment option for pain in the middle-aged patient with a focal articular cartilage defect in the knee.
