Autologous collagen-induced chondrogenesis versus microfracture for chondral defects of the knee: Surgical technique and 2-year comparison outcome study.

OBJECTIVE: Osteochondral lesions of the knee affect patients from all age groups with arthroscopic microfracture being the current gold standard of treatment of such lesions. Autologous collagen-induced chondrogenesis (ACIC) is a novel procedure that has recently been gaining popularity. This study aims to compare the 6 and 24 month post-operative outcomes between patients undergoing microfracture only and microfracture with ACIC. METHODS: Patients from both groups were assessed pre-operatively, at 6 and 24 months post-operatively for functional outcomes using SF-36 and IKDC scoring (International Knee Documentation Committee Subjective Knee Form). RESULTS: Both groups showed improved SF-36 and IKDC scores at 6 and 24 months, however patients who underwent ACIC showed better SF-36 mental component and IKDC scores 24 months after surgery. CONCLUSION: This demonstrates that ACIC is an effective, single-stage, joint-preserving procedure which is comparable, if not better, in treating chondral defects.

Outcomes are favorable in Asian patients undergoing deltoid-on open rotator cuff repair without acromioplasty.

BACKGROUND: To evaluate if rotator cuff repair without acromioplasty would result in improvement in outcomes without the risks associated with acromioplasty in Asian patients. METHODS: 38 primary repairs of tears of the rotator cuff were performed through a deltoid-on approach. The Simple Shoulder Test (SST) and UCLA shoulder rating scale were measured preoperatively and at 2 years post-operatively. RESULTS: There was a significant improvement in the SST 2 years post-operatively (p < 0.001). UCLA scores for pain control and function (p < 0.001) also significantly improved 2 years post-operatively. CONCLUSION: Outcomes are favorable in Asians following deltoid-on open rotator cuff repair without acromioplasty. LEVEL OF EVIDENCE: III.
