Randomized Controlled Trial Comparative StudyComputer-navigated versus conventional total knee arthroplasty a prospective randomized trial.
The literature lacks studies that confirm whether the improved radiographic alignment that can be achieved with computer-navigated total knee arthroplasty improves patients’ activities of daily living or the durability of total knee prostheses. The purpose of this study was to determine whether computer-navigated total knee arthroplasty improves the clinical function, alignment, and survivorship of the components. ⋯ Our data demonstrated no difference in clinical function or alignment and survivorship of the components between the knees that underwent computer-navigated total knee arthroplasty and those that underwent conventional total knee arthroplasty.

Randomized Controlled Trial Comparative StudyOutcomes of operative treatment of unstable ankle fractures: a comparison of metallic and biodegradable implants.
Biodegradable implants for internal fixation of ankle fractures may overcome some disadvantages of metallic implants, such as imaging interference and the potential need for additional surgery to remove the implants. The purpose of this study was to evaluate the outcomes after fixation of ankle fractures with biodegradable implants compared with metallic implants. ⋯ The outcomes after fixation of bimalleolar ankle fractures with biodegradable implants were inferior to those after fixation with metallic implants in terms of the score on the AOFAS scale and time to bone union. However, the difference in the final AOFAS score between the groups may not be clinically important. The outcomes associated with the use of biodegradable implants for the fixation of isolated lateral malleolar fractures were comparable with those for metallic implants.

Randomized Controlled Trial Comparative StudyTotal hip replacement versus open reduction and internal fixation of displaced femoral neck fractures: a randomized long-term follow-up study.
Clinical trials with short and intermediate-term follow-up have demonstrated superior results for total hip replacement as compared with internal fixation with regard to hip function and the need for secondary surgery in elderly patients with a displaced intracapsular femoral neck fracture. The aim of the present study was to compare the results of total hip replacement with those of internal fixation over a long-term follow-up period of seventeen years. ⋯ Therapeutic Level I.
