Randomized Controlled Trial Meta Analysis
Patellar resurfacing versus nonresurfacing in total knee arthroplasty: a meta-analysis of randomised controlled trials.
Patella resurfacing or nonresurfacing in total knee arthroplasty remains controversial. The aim of this study was to evaluate the efficacy of patellar resurfacing through an evaluation of the current literature. ⋯ The available evidence indicates that patellar resurfacing reduces the risk of reoperation after total knee arthroplasty. Patellar resurfacing patients may make a difference in long-term follow-up (five or more 5 years) of Knee Society scores. In other aspects, the benefit of patellar resurfacing is limited. Additionally, more carefully and scientifically designed randomised controlled trials are required to further prove the claim.

Randomized Controlled Trial
Design and application of nickel-titanium olecranon memory connector in treatment of olecranon fractures: a prospective randomized controlled trial.
We carried out this study to test the efficacy of the olecranon memory connector (OMC) in olecranon fractures. ⋯ The study showed that OMC could be an effective alternative to treat olecranon fractures.

Comparative Study
Perioperative mortality in hip fracture patients treated with cemented and uncemented hemiprosthesis: a register study of 11,210 patients.
Adverse events associated with the use of bone cement for fixation of prostheses is a known complication. Due to inconclusive results in studies of hip fracture patients treated with cemented and uncemented hemiprostheses, this study was initiated. ⋯ We found increased mortality for the cemented hemiprosthesis the first post-operative day compared to uncemented procedures. This increased risk is closely related to patient comorbidity estimated by the patient's ASA score.

Pelvis ring fractures of geriatric patients are currently a serious problem in orthopedic and trauma surgery. One controversy that remains is the insufficiency fracture of the sacrum with treatment options ranging from conservative to operative. We modified standard 7.3-mm screws with additional perforations at the tip to allow cement injection trough the screw to improve implant anchorage. ⋯ The described procedure for the treatment of sacral insufficiency fractures has the potential to increase the safety of cement injection into the sacrum because of the possibility of contrast agent instillation prior to cement injection. Furthermore, the amount of cement can be reduced and additional stability can be attained due to iliosacral screw osteosynthesis compared to sacroplasty.

The purpose of this study is to determine the long term-results after thoracoscopic spondylodesis particularly with respect to a ventral versus dorso-ventral treatment strategy. ⋯ The ventral thoracoscopic approach to the spine seems to be a safe therapeutic strategy. A dorso-ventral treatment concept goes along with a higher operative reduction potential.
