Sub-chondroplasty Reduces Pain, Improves Function and Delays the Conversion to Arthroplasty in Patients with Advanced Knee Osteoarthritis: A Stratified Meta-analysis and Quality Assessment.

There is an ongoing interest in alternatives to total knee arthroplasty, as a means to delay inevitable replacement. A possible, minimally invasive, alternative is a sub-chondroplasty, involving interosseous injection of bone substitute materials such as calcium phosphate (CaPo4), platelet-rich plasma (PRP), bone marrow aspirate concentrate (BMAC) or Injectable demineralized bone matrix (iDBM) into the subchondral bone. Eleven clinical trials were found, investigating the effectiveness of sub-chondroplasties performed using CaPo4, PRP, BMAC, and iDBM.

Genetic Polymorphisms Associated with Perioperative Joint Infection following Total Joint Arthroplasty: A Systematic Review and Meta-Analysis.

The number of orthopedic procedures, especially prosthesis implantation, continues to increase annually, making it imperative to understand the risks of perioperative complications. These risks include a variety of patient-specific factors, including genetic profiles. This review assessed the current literature for associations between patient-specific genetic risk factors and perioperative infection.
