Advanced Multi-Layer Watertight Closure versus Conventional Closure in Total Hip and Knee Replacement Surgery.

Background: In total joint replacement procedures, surgeons have increasingly adopted advanced multi-layer, watertight closure. The objective of the study was to compare the clinical and economic outcomes for advanced multi-layer, watertight closure patients to those with conventional closure with sutures and skin staples.

Methods: Patients aged ≥18 years were included in the study if they underwent total joint arthroplasty of the hip or knee as an elective, primary, inpatient procedure between January 2014 and March 2019.

Prospective, Randomized Study of Direct Anterior Approach vs Posterolateral Approach Total Hip Arthroplasty: A Concise 5-Year Follow-Up Evaluation.

Background: Interest in direct anterior approach (DAA) has increased over the last decade. In our previously published study comparing DAA to posterolateral approach (PA), early 3-month benefits were noted in terms of pain and function. There was no difference noted at 6 or 12 months.

The use of metaphyseal sleeves in revision total knee arthroplasty.

Background: Bone loss in revision total knee arthroplasty is common. Various reconstruction options are available. The purpose of our study is to report on one such reconstruction option, titanium metaphyseal sleeves.

Prospective randomized study of direct anterior vs postero-lateral approach for total hip arthroplasty.

Benefits of a direct anterior approach (DAA) versus a posterior-lateral (PA) approach to THA were assessed in a single-surgeon, IRB-approved, prospective, randomized clinical study. Subjects (43 DAA and 44 PA) were evaluated at 6 weeks, and 3, 6 and 12 months. The primary end point was ability to climb stairs normally and walk unlimited at each time point.

Large-diameter modular metal-on-metal total hip arthroplasty: incidence of revision for adverse reaction to metallic debris.

Large-diameter modular metal-on-metal (MOM) total hip arthroplasty (THA) may offer reduction in wear debris and improved stability. Four studies are summarized here that used a large-diameter modular MOM system. A total of 1076 THAs were performed.

Comparison of radiographic alignment of imageless computer-assisted surgery vs conventional instrumentation in primary total knee arthroplasty.

A total of 208 patients were enrolled in a multicenter, prospective randomized, institutional review board-approved study that compared preoperative surgical plan to postoperative 2-dimensional radiographic alignment measured by a blinded reviewer for primary total knee arthroplasty (TKA) implanted using computer-assisted surgery (CAS) compared with conventional TKA instrumentation. The results demonstrated a statistically significant improvement in the coronal tibial component alignment (P < .03) and failed to demonstrate a statistically significant improvement in the mechanical axis, femoral coronal/sagittal, and tibial sagittal alignment.

The need for gender-specific prostheses in TKA: does size make a difference?

Aging boomers and younger patients requiring total knee arthroplasty demand and/or expect better function, improved durability, and a quicker recovery. In response to this demand, surgeons are modifying surgical techniques, and industry is examining implant design. One proposal is the gender-specific implant, but the development of separate systems for men and women may prove to be unnecessary.
