Cemented Constrained Liners Used as an Articulating Hip Spacer for the Treatment of Chronic Prosthetic Joint Infection.

Background: Two-stage exchange arthroplasty remains the gold standard for treating chronic hip periprosthetic joint infections. However, controversy remains regarding the optimal spacer type, particularly among patients with increased dislocation risk. This study reports on the outcomes of articulating hip spacers utilizing a single constrained-liner design.

The Literature that Commercial Insurance Payers Use to Substantiate Knee Osteochondral Allograft Policies Are of a Low Level of Evidence.

Objective: The purpose of this study is to analyze how the largest insurance companies support their medical necessity policies regarding osteochondral allograft transplantation (OCA) and to determine whether the literature they cite in their policies is of a high level of evidence (LOE).

Design: The 10 largest national health insurance companies were identified. Each payer was contacted via phone or email to obtain their coverage policy regarding OCA.

Results of Randomized Controlled Trials of Platelet-Rich Plasma in Lower-Extremity Tendinopathy Are Not Influenced by Industry Sponsorship.

Purpose: To determine whether industry affiliation influences the results of randomized controlled trials (RCTs) studying the use of platelet-rich plasma (PRP) for the treatment of patellar or Achilles tendinopathy.

Methods: The PubMed, Scopus, Cochrane, and MEDLINE databases were searched in July 2023 for RCTs investigating PRP for the treatment of patellar or Achilles tendinopathy published between 2009 and July 2023. Industry affiliation was determined by analyzing each study's funding or conflict-of-interest section.

Evaluation of spin in systematic reviews on the use of tendon transfer for massive irreparable rotator cuff tears.

Purpose: To identify, describe and account for the incidence of spin in systematic reviews and meta-analyses of tendon transfer for the treatment of massive, irreparable rotator cuff tears. The secondary objective was to characterize the studies in which spin was identified and to determine whether identifiable patterns exist among studies with spin.

Methods: This study was conducted per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
