Osteotomy for treating knee osteoarthritis

Researchers from The Cochrane Collaboration conducted a review of the effects of an osteotomy in people with osteoarthritis of the knee. Upon searching for all relevant studies until November 2013, they found 21 studies that included up to 1065 people. Their findings are summarised below.

Comparison of high tibial osteotomy and unicompartmental knee arthroplasty in the treatment of unicompartmental osteoarthritis: a meta-analysis

We conducted a systematic review of comparative clinical trials assessing the results of high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) in patients with strictly unilateral osteoarthritis of the knee. A literature search was conducted through Medline, Embase and Cochrane library. A total of 11 comparative studies were included. Pooled results showed: UKA showed significantly better results compared to HTO in terms of function results, however, no difference in specific knee score was observed; HTO got slightly better results of the range of motion; a trend towards an increased velocity was found in UKA without significant difference. Postoperative rate of revision and complications did not differ significantly between two groups. With the correct patient selection, both HTO and UKA show effective and reliable results.

Treatments for adults with prominent lower front teeth

Prominent lower front teeth may be associated with a large or prominent lower jaw and/or a small or retrusive upper jaw. The reasons why this occurs are not well understood. Several treatments have been proposed including orthopedics, functional appliances, interceptive and/or corrective orthodontics, and surgery for the more severe cases, but we found only two trials, each evaluating a different approach. Both of the trials were small and did not provide adequate data for assessing the effectiveness of the treatments.

Surgical techniques for fixing extracapsular hip fractures in adults

Roughly half of all hip fractures are outside the hip joint capsule (extracapsular proximal femoral fractures). Many of these will be fixed or stabilised using metal implants which are a combination of screws, rods and plates attached to the thigh bone. Various techniques such as the selective removal of bone (osteotomy), the pressing together of bone fragments (compression), the addition of bone cement, and methods for insertion of nails such as reaming, are used during surgery. This review included 11 randomised or quasi‐randomised trials. The majority of the participants were female, usually aged around 80 years. There were seven comparisons but the evidence for each of these was insufficient to draw conclusions. Thus, the review found that there was too little evidence from randomised trials to show which, if any, specific surgical techniques used during operations for extracapsular proximal femoral fractures are better.
