Is Topical Vancomycin an Option? A Randomized Controlled Trial to Determine the Safety of the Topical Use of Vancomycin Powder in Preventing Postoperative Infections in Total Knee Arthroplasty, as Compared With Standard Postoperative Antibiotics.

Background: The demand for total knee arthroplasties (TKAs) is expected to rise in the coming decades, increasing the burden of periprosthetic joint infections (PJIs). The use of intrawound vancomycin powder (VP) has proven to be effective in reducing the incidence of PJIs after spinal surgery. That said, its effectiveness in TKA remains unclear.

An evaluation of the apprehension, relocation, and surprise tests for anterior shoulder instability.

Background: Although there are many studies describing tests for shoulder instability, there are few assessing the validity of these tests in diagnosing anterior shoulder instability.

Purpose: To assess the validity of the apprehension, relocation, and surprise tests as predictors of anterior shoulder instability.

Study Design: Retrospective review of prospectively collected data.

The John Charnley Award: Three-dimensional analysis of the cement mantle in total hip arthroplasty.

Cemented fixation of the femoral stem is the gold standard for patients older than 60 years. The importance of reliably achieving an adequate cement mantle has been shown in many studies. Currently, inspection and grading of plain radiographs is the accepted method for study of the cement mantle.

Patient satisfaction and outcome after septic versus aseptic revision total knee arthroplasty.

A consecutive series of revision total knee arthroplasties performed at 3 university-affiliated centers by 3 surgeons was prospectively studied. The same implant was used in all cases. The evaluation included a Knee Society clinical score (KSCS); SF-36; satisfaction survey; and radiographs preoperatively, at 6 and 12 months postoperatively, and annually thereafter.

The effect of built-in external femoral rotation on patellofemoral tracking in the genesis II total knee arthroplasty.

External rotation of the femoral component during total knee arthroplasty (TKA) has been suggested to improve flexion space balancing and patellofemoral tracking. Incorporation of external rotation into the design of the femoral component offers an alternative method to achieve this goal. This study compared 150 TKAs performed with traditional external rotation of the femoral component on the distal femur with a similar group of 150 TKAs performed with an implant that incorporates 3 degrees of external rotation into the femoral component.

Prevalence of heterotopic ossification in cemented versus noncemented total hip joint replacement in patients with osteoarthrosis: a randomized clinical trial.

Objective: To determine the prevalence of heterotopic bone formation in cemented versus noncemented total hip joint replacement.

Design: A prospective randomized controlled trial. Follow-up ranged from 2 to 6 years (mean 4 years).
