QC Kinetix grew to 184 clinics on marketing and is now down to about 102, facing class actions alleging promised cures and five-figure financed plans. Biologics practiced as medicine means a real evaluation, plain talk about the evidence, and no sales floor.

Cold weather doesn't cancel training - it changes the rules. Talked with @foxweather on staying safe: moisture-wicking base (cotton kills in the cold), protect extremities early, warm up longer, respect wind chill. foxweather.com/watch/play-6b… #SportsMedicine #WinterTraining

Lipogems: your own fat is harvested, microfragmented, and injected into the arthritic joint. Fat is rich in signaling cells; the graft acts as a scaffold. For knee OA when PRP wasn't enough. Educational only - not medical advice. #Orthobiologics #SportsMedicine @OrthoColumbia

Proud to have a small hand in this. TIME named Columbia's NovaKnee a Best Invention of 2026: a living, 3D-printed knee seeded with stem cells. I collected those cells - Lipogems lipoaspirate, cultured by the team. Regeneration over replacement. time.com/collection/best-inv…

Our JBJS study: preseason patellar tendon thickness on ultrasound predicted jumper's knee in D1 men's basketball players. A 60-second scan flagging at-risk athletes before symptoms start - screening as prevention. pubmed.ncbi.nlm.nih.gov/4010… #SportsMedicine #Tendinopathy

10 years in the making. Finally ready. Students who used a QBank early were 2.73x more likely to pass boards on time. I built 1,235 questions from scratch for the 2026 sports med CAQ. @TheAMSSM @ACSMNews @TheABFM — would love your eyes on this. sportsmedcaq.com

Tendinopathy follows a ladder: 1) load management + eccentric PT 2) relative rest 3) guided injection 4) orthobiologics 5) surgery for the few who fail everything. Don't repeat rung 3 forever. Educational only - not medical advice. #SportsMedicine #Tendinopathy @OrthoColumbia

Is tennis the healthiest sport? Told @TODAYshow: "Tennis is one of the most intense sports you can play with some of the highest health benefits." Racquet sports top the longevity studies. Find the sport you'll still play at 70. worldwiretimes.com/is-tennis… #SportsMedicine #Longevity

Knee arthritis doesn't jump to replacement. My ladder: 1) activity mod + PT 2) weight optimization 3) bracing/injections 4) orthobiologics 5) surgery - last. Right treatment, right time, right knee. Educational only - not medical advice. #SportsMedicine #KneeArthritis

1,169 images from my own procedure cases over 10 years - close to the number of Lipogems procedures I've performed. My Lipogems team tells me I'm the highest-volume user in Manhattan. Proud to ride the forefront of evidence-based care. #Orthobiologics #SportsMedicine

Will knee replacement become common for elite skiers? @AP interviewed me in St. Moritz on Lindsey Vonn's titanium knee when I covered her first race back on the World Cup circuit. @usskiteam physician: context is the whole game apnews.com/article/lindsey-v… #SportsMedicine #Orthopedics

PRP: blood drawn, spun to concentrate platelets, injected under ultrasound into the injured tissue. Best evidence: tendinopathies, mild-moderate knee OA. A tool, not a miracle — selection is everything. For education only — not medical advice. #PRP #SportsMedicine @ColumbiaOrtho

The most complete walkthrough of my practice: a deep dive on orthobiologics — PRP, mesenchymal signaling cells, A2M. Which biologic for which problem, what the evidence supports, where the field is headed. youtube.com/watch?v=54EHvO0U… #Orthobiologics #SportsMedicine @ProClinix

My new website is live → drgoldwaser.com Home base for my Columbia sports-medicine practice, my orthobiologics work, and the educational content I share with patients and clinicians. Take a look. #SportsMedicine

"Doc, should I try peptides?" Peptides signal cells to repair — but science is early while marketing runs ahead. Compounded products vary. They don't replace load management, PT, sleep, nutrition. Educational only — not medical advice. #SportsMedicine #Orthobiologics

drgoldwaser.com is live — one home base for my practice at Columbia/NYP, team coverage, media & how to reach me. Link below 🏥

"Wild West" of peptides is booming — patients ask me every week. Spoke with @CNN on what's real, what's risky, what's next. Real potential, but optimism isn't evidence. Data has to lead. cnn.com/2026/04/13/health/pe… #SportsMedicine #Orthobiologics
