Kevin Jurgensmeier, Darin Jurgensmeier MD, Derek E. Kunz, Peter G. Fuerst, Lucian C. Warth, Steven B. Daines
doi : 10.1016/j.arth.2020.08.036
VOLUME 36, ISSUE 2, P416-422, FEBRUARY 01, 2021
Clinicians commonly utilize intra-articular injections to treat symptomatic primary arthritis. Steroid injections are common yet have immune-modulating effects and can alter gene expression which may delay definitive arthroplasty and further damage cartilage. Nonsteroidal anti-inflammatory injections may offer a safer profile due to their differing mechanism of action; however, there is a relative dearth of information regarding their efficacy. This noninferiority study compares the effectiveness of triamcinolone vs ketorolac in treating symptoms of moderate to advanced primary osteoarthritis of the hip and knee.

Multiply revised total knee arthroplasties (TKAs) may present with large anterior soft tissue defects, which can be challenging to reconstruct. In the rare cases where local flaps are insufficient, we use free latissimus dorsi (LD) myocutaneous flaps to achieve soft tissue coverage. This study looked to determine implant survivorship, infection status, and patient-reported outcomes of patients undergoing simultaneous revision TKA and LD flaps in a tertiary unit.

doi : 10.1016/j.arth.2020.08.042
VOLUME 36, ISSUE 2, P777-787.E1, FEBRUARY 01, 2021
Debate surrounds the use of cemented or uncemented prostheses for the treatment of displaced femoral neck fractures (FNF). Many guidelines recommend the use of the cemented hemiarthroplasty (CHA). Proponents of CHA point out the increased re-operation rate while proponents of uncemented hemiarthroplasty (HA) highlight the increased mortality rate in the perioperative period. The aim of this study was to systematically review the literature to evaluate perioperative mortality after HA for displaced FNFs.
