Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 4, 2026 | Last Updated: March 4, 2026 Back pain is one of the most common complaints I encounter in my sports medicine practice — and one of the most misunderstood. Patients arrive convinced they have a serious spinal problem, that their MRI findings explain their symptoms, or that rest is the only safe path forward. These beliefs are not only unsupported by current evidence; they ac

Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 3, 2026 | Last Updated: March 3, 2026 In my practice, one of the most common questions I hear from patients with knee arthritis is whether exercise is safe — and more specifically, whether strength training will make their joints worse. The evidence is clear: not only is strength training safe for most people with knee osteoarthritis, it is among the most effective interventions we have for red

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 4, 2026 | Last Updated: March 4, 2026 Knee cartilage lesions — including chondromalacia and osteochondral defects — have long been considered irreversible. Once cartilage wears down or detaches, the conventional wisdom has been that it simply cannot regenerate on its own. However, emerging evidence suggests that platelet-rich plasma (PRP) injections may not only reduce pain and impr
