Objective: The purpose of this study was to investigate of the factors affected Short-term Outcomes in ACI (®JACC).
Methods: The objects were 38 patients who were underwent JACC over 12 months with mean age 46.9 years. Isolate cartilage defect site was femoral medial condyle (MFC) 21 knees, femoral lateral condyle (LFC) 2 knees, tibia lateral condyle1 (TLC) knees, patella (P) 4 knees, femoral trochlar (Tr) 1 knee. Combined cartilage defect site were MFC+Tr 2 kees, LFC+Tr 1 kees, P+Tr 5 kees, MFC+P+Tr 1 knee. Mean cartilage defect area was 649.7±284.1 (400-1850) mm2. KOOS (KOOS), Lysholm score (Lysholm) were evaluated as clinical score, and investigated both correlation with age, BMI and defect area and association with gender, implantation procedure and HTO.
Results: In all objects, 26, 52 weeks KOOS each items and Lysholm were higher significantly than previous that without 26 weeks sports item of KOOS. Complication after JACC was 4 Hypertrophys, 1 separation and 1 contracture which was underwent immobilization at 3 months after JACC. Post-operative KOOS under 30 years was significantly higher than that over 30 years without symptom items. There was no significant difference between with HTO and without HTO. But, Amount of KOOS changes from preoperative to postoperative with HTO was significant higher than that without HTO.
Conclusions: Large cartilage defect area, under 30 years and with HTO affected JACC good short-term outcomes.
