Cemented femoral stem fixation through the anterior approach has fewer early complications than cementless fixation.

Aims: To achieve the functional benefits of the direct anterior (DA) approach and the fixation benefits of cemented replacement, this study combined the two techniques posing the following questions: does the limited access of the DA approach adversely affect the cement technique?; and does such a cementing technique reduce the incidence of cementless complications?

Methods: A consecutive series of 341 patients (360 hips) receiving the DA approach between 2016 and 2018 were reviewed. There were 203 cementless stems and 157 cemented stems. Mean age was 75 years (70 to 86) in the cementless group and 76 years (52 to 94) in the cemented group, with 239 (70%) females in the whole series.

Is Routine Hardware Removal Following Open Reduction Internal Fixation of Tarsometatarsal Joint Fracture/Dislocation Necessary?

Open reduction internal fixation (ORIF) is an accepted treatment for displaced tarsometatarsal joint (TMTJ) fracture dislocations. In general, hardware is routinely removed after 4 months to allow restoration of joint motion and avoid complications of hardware failure. Because few studies report outcomes of TMTJ fractures with retained hardware, there is little consensus regarding the optimal time for hardware removal or if hardware retention leads to adverse outcomes.

Modern Day Bicruciate-Retaining Total Knee Arthroplasty: A Short-Term Review of 146 Knees.

Background: Bicruciate retaining (BCR) implants were first proposed in the 1960s with the polycentric knee. Given the technical difficulty of implanting these devices, and the mixed results at the time, the BCR concept had stalled, until recently. This study seeks to provide a short-term review of the BCR implant design, describe patient-reported outcomes, and discuss key aspects to ensure successful implantation of the modern-day BCR implant design.

Increasing Liner Anteversion Decreases the Interfacial Strength of Polyethylene Liners Cemented Into Titanium-Alloy Acetabular Shells.

Background: Acetabular component positioning during revision total hip arthroplasty can be suboptimal. Cementation of an acetabular liner into a well-fixed acetabular shell can allow surgeons to correct component version and inclination without the need for extensive revision surgery and progressive pelvic bone loss. However, to date, it is unknown what degree of version can be corrected without sacrificing fixation strength of the construct.
