In my practice as a sports medicine physician, I meet patients every day who are anxious about their diagnosis and overwhelmed by conflicting advice. The good news is that there are three

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 3, 2026 | Last Updated: March 3, 2026 Knee cracking, popping, and grinding are among the most common concerns I hear from patients in my sports medicine clinic. These sounds — collectively known as knee crepitus — can be alarming, especially when they seem to appear out of nowhere. The good news is that in most cases, noisy knees are completely harmless. However, understanding when c

While surgical repair is necessary in some cases, the majority of rotator cuff tears can be successfully managed without an operation — provided you take the right steps to support your recovery. As a sports medicine physician, I h

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 3, 2026 | Last Updated: March 3, 2026 Push-ups are one of the most basic exercises in fitness, but they may reveal far more about your health than you realize. In my practice as a sports medicine physician, I frequently see how muscular strength — or the lack of it — directly impacts long-term health outcomes. A landmark study published in the Journal of the American Medical Associat

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 2, 2026 | Last Updated: March 2, 2026 If you live with arthritis, you may have been told — or simply assumed — that pain is a sign of ongoing joint damage. This belief is not only inaccurate in many cases, but it can actually make your arthritis worse. The fear of pain leads to avoidance of movement, which sets off a cycle of weakness, stiffness, and accelerated joint decline. In my

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 2, 2026 | Last Updated: March 2, 2026 Knee osteoarthritis is one of the most common causes of joint pain in adults, affecting mobility, independence, and overall quality of life. Exercise remains one of the most effective non-pharmacological treatments for managing symptoms—but patients frequently ask which type of exercise is best. Strength training has long been considered the gold

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2025 | Last Updated: March 1, 2025 Most people who struggle with joint pain are focused on the wrong things. They wait for the pain to go away on its own. They rest for weeks—sometimes months—hoping time will fix the problem. They stretch when they should be strengthening. And they treat the symptoms without ever addressing the underlying system. In my practice, I see these patter

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2025 | Last Updated: March 1, 2025 Shoulder pain is one of the most common musculoskeletal complaints I encounter in my sports medicine practice, and it is also one of the most misunderstood. Most shoulder problems do not develop from a single dramatic injury. Instead, they build gradually over time from tight muscles, poor movement habits, and the cumulative effects of everyday w

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2025 | Last Updated: March 1, 2025 Maintaining strength, mobility, and independence as you age is not only possible — it is well within reach for most people. Whether you are in your 60s, 70s, or beyond, the same foundational principles apply: move consistently, train with intention, and prioritize recovery. In my practice, I work with patients every day who are proving that age i

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2025 | Last Updated: March 1, 2025 Movement is medicine — but most people with arthritis do the exact opposite. When joint pain flares, the instinct is to stop moving: skip the walk, avoid the stairs, rest as much as possible. The problem is that avoidance does not protect your joints. In my practice, I see this pattern regularly — patients who stop moving in an effort to manage t

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2026 | Last Updated: March 1, 2026 Shoulder pain is one of the most common complaints I see in my sports medicine practice, and certain patterns consistently stand out as early warnings of a more serious underlying problem.

In this guide, I'll walk you through everything you need to

Written by Dr. Jeffrey Peng, MD — Board-Certified Sports Medicine Physician Published: March 1, 2026 | Last Updated: March 1, 2026 One of the most common questions I hear from patients considering platelet-rich plasma therapy is: "Do PRP injections hurt?" Most people assume it is just another quick, relatively painless shot. And while that is often true during the procedure itself, the real surprise comes a few hours later — and it can catch people completely off guard. In m

It does not simply sit there quietly — it actively drives systemic inflammation, fuels metabolic s
