Stem Cells in Orthopedic Rheumatology: Where Clinical Signals Are Strongest
Stem-cell therapies in orthopedic rheumatology offer dual promise: immunomodulation and tissue repair. This editorial reviews 2023-2025 evidence across key rheumatic diseases, identifying where clinical signals are strongest. Mesenchymal stromal/stem cells (MSCs) show encouraging immunologic and symptomatic benefits in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), particularly lupus nephritis, with acceptable short-term safety. However, trial heterogeneity in MSC source, dose, and manufacturing limits reproducibility.

Leukocyte-Poor Platelet-Rich Plasma Reduces Retear Risk After Arthroscopic Rotator Cuff Repair: A Meta-Analysis with Mechanistic and Economic Evaluation
Rotator cuff repair (RCR) is one of the most common orthopedic procedures, yet 20%-40% of repairs fail structurally within two years, leading to pain, functional decline, and costly revision surgery. Platelet-rich plasma (PRP) has been proposed to enhance tendon–bone healing, but prior reviews frequently pooled heterogeneous formulations as a homogeneous intervention, producing conflicting conclusions.

Exercise interventions for rotator cuff-related shoulder pain in middle-aged and older adults: a systematic review and meta-analysis
Rotator cuff-related shoulder pain is highly prevalent in middle-aged and older adults and is associated with pain, functional limitations, and reduced quality of life. This systematic review and meta-analysis aimed to evaluate the effectiveness of exercise-based interventions on pain, function, range of motion (ROM), and strength in middle-aged and older adults with rotator cuff-related shoulder pain.

Arthroscopic Treatment of Patellar Clunk Syndrome After Total Knee Arthroplasty
Patellar clunk syndrome is a complication of total knee arthroplasty. Surgical treatment with arthroscopic irrigation and debridement and lysis of adhesions is often required when conservative treatment fails. This study examines patient improvement following arthroscopic treatment of patellar clunk.

One injection reversed osteoarthritis in weeks
A Colorado research team has created experimental osteoarthritis treatments that appear to regenerate damaged joints rather than just relieve pain. In animal studies, a single injection restored arthritic joints to a healthy state within weeks, while a second therapy repaired cartilage and bone defects by harnessing the body’s own healing cells.
