The purpose of this article is to review the early complications of minimally invasive mobile-bearing unicompartmental knee arthroplasty by analyzing the first 100 consecutive cases. All cases were medial unicompartmental arthroplasties with a follow-up of at least 24 months (range, 24-51 months). ⋯ However, there exists a high rate of early failures, which occurred during the initial learning curve. Therefore, surgeons must be aware that in order to minimize these complications, attention to detail is mandatory.

The purpose of this study was to determine the mortality rate and factors related to mortality in elderly patients with acute and monotraumatic femoral neck fractures. This study included 241 patients with femoral neck fractures after bipolar hemiarthroplasty. ⋯ There proved to be a relationship between postoperative mortality and age, the time to surgery, and the Society of Anesthesiologists score. We recommend that surgery should not be delayed, and caution should be exercised for the high-risk group patients.

This study was designed to evaluate the midterm results of hybrid total hip arthroplasty in a consecutive series of 45 Chinese patients with osteoarthritis secondary to dysplastic hip. The average follow-up was 6.6 years. A total of 24 hips were classified as dysplasia, 20 hips as low dislocation, and 13 hips as high dislocation. ⋯ With the use of loosening or revision as the end point for failure, the survival rate was 1.0. We suggest that hybrid total hip arthroplasty in Chinese developmental dysplasia of hip patients has favorable results at midterm follow-up, even though their lifestyle includes more deep flexion of the hip. There is no significant difference of postoperative Harris score with increasing severity of dysplasia.
