Randomized Controlled Trial Multicenter Study Comparative StudyOpen reduction and internal fixation compared with circular fixator application for bicondylar tibial plateau fractures. Surgical technique.
Standard open reduction and internal fixation techniques have been successful in restoring osseous alignment for bicondylar tibial plateau fractures; however, surgical morbidity, especially soft-tissue infection and wound necrosis, has been reported frequently. For this reason, several investigators have proposed minimally invasive methods of fracture reduction followed by circular external fixation as an alternative approach. To our knowledge, there has been no direct comparison of the two operative approaches. ⋯ Both techniques provide a satisfactory quality of fracture reduction. Because percutaneous reduction and application of a circular fixator results in a shorter hospital stay, a marginally faster return of function, and similar clinical outcomes and because the number and severity of complications is much higher with open reduction and internal fixation, we believe that circular external fixation is an attractive option for these difficult-to-treat fractures. Regardless of treatment method, patients with this injury have substantial residual limb-specific and general health deficits at two years of follow-up.

Randomized Controlled Trial Comparative StudyComputer-assisted minimally invasive total knee arthroplasty compared with standard total knee arthroplasty. Surgical technique.
There is little information on the feasibility of computer navigation when using a minimally invasive approach for total knee arthroplasty, during which the anatomic landmarks for registration may be obscured. The purpose of the present study was to determine the radiographic accuracy of this technique and to compare the rate of functional recovery between patients who underwent computer-assisted minimally invasive arthroplasty and those who underwent conventional total knee arthroplasty. ⋯ Although specific clinical parameters reflect an early increased rate of functional recovery in association with computer-assisted minimally invasive total knee arthroplasty within the first postoperative month, the main advantage of this technique over conventional total knee arthroplasty is improved postoperative radiographic alignment without increased short-term complications.

Randomized Controlled Trial Comparative StudySlower recovery after two-incision than mini-posterior-incision total hip arthroplasty. Surgical technique.
It has been claimed that the two-incision total hip arthroplasty technique provides quicker recovery than other methods do. To date, however, there have been no studies that have directly compared the two-incision technique with another method in similar groups of patients managed with the same advanced anesthetic and rehabilitation protocol. We posed the hypothesis that patients managed with two-incision total hip arthroplasty would recover faster than those managed with mini-posterior-incision total hip arthroplasty and designed a randomized controlled trial specifically (1) to determine if patients recovered faster after two-incision total hip arthroplasty than after mini-posterior-incision total hip arthroplasty as measured on the basis of the attainment of functional milestones that reflect activities of daily living, (2) to determine if the general health outcome after two-incision total hip arthroplasty was better than that after mini-posterior-incision total hip arthroplasty as measured with Short Form-12 (SF-12) scores, and (3) to evaluate the surgical complexity of the two procedures on the basis of the operative time and the prevalence of early complications. ⋯ Our hypothesis that the two-incision technique for total hip arthroplasty would substantially improve the short-term recovery after total hip arthroplasty compared with the mini-posterior-incision technique was not proved; instead, the patients managed with the mini-posterior-incision technique had the quicker recovery.
