Mean follow-up was 11.6 +/- 0.8 years. Nine graft ruptures occurred. The satisfaction rate was excellent (90%). Seventy patients (74%) were still actively participating in sports. The mean subjective IKDC 2000 score was 90.5 +/- 8.8 points. The IKDC score was statistically correlated to laxity, time from injury, and osteoarthritis development at final follow-up. Ninety-one percent of patients were graded A or B according to the overall IKDC score. The radiological assessment reported osteoarthritis development in 17.8% of patients, and 39% showed radiological changes. Osteoarthritis was correlated with body mass index (P = .01) and age at follow-up (P = .006). In a selected population without meniscus and articular cartilage injury, an osteoarthritis rate of only 8% was found. Conclusion Arthroscopic anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft resulted in high patient satisfaction levels and good clinical results after 10 years. Moreover, a high percentage of patients remained involved in sports activities, and anterior cruciate ligament reconstruction protected their meniscus from a secondary tear. However, knee osteoarthritis developed in 17.8% of patients so treated.

Long-term results of a retrospective series of primary arthroplasty with the original cementless dual mobility socket (A) and the midterm results with the second generation (B) are reported. In series A (follow-up 16.5 years) 437 total hip arthroplasties (THA) were included and in series B (follow-up five years) 231 hips. The 15-year survival rate was 84.4 ± 4.5% (revision for any reason as endpoint); 30 hips (6.8%) were revised for aseptic loosening. Five THA were revised for dislocation: two early and three after ten years or more. With the second generation socket neither dislocation nor revision for mechanical reasons were observed. The survival rate was 99.6 ± 0.4% (revision for any reason). The prevalence of revision for dislocation was very low in our series. This concept does not avoid wear and aseptic loosening, especially in young active patients, but the long-term stability has been confirmed. Dual mobility can be recommended for patients over 70 years of age and for younger patients with high risk of dislocation.

III. Prospective consecutive nonrandomized multicenter study.

Autologous osteochondral mosaicplasty seems to be a reliable technique in the short and intermediate term. It has the advantage of being less expensive than reconstructive techniques, is a one-step surgical procedure and results in immediate restoration of cartilage surface. Nevertheless, this is a difficult technique, which may result in complications and requires articular harvesting. This technique is limited by the size of the defect to be treated. The primary indication is deep, small defects on the medial femoral condyle.
