Rotator Cuff Pain, No Scalpel: Stem Cell Therapy in Phoenix

You felt it happen. That sharp pain in your shoulder during your workout, tennis serve, or swim stroke. Now you’re facing the diagnosis every athlete dreads: rotator cuff tear. Your orthopedic surgeon is talking about months of recovery after surgery, but your season starts in 8 weeks.

There’s another way.

At Arizona Pain and Spine Institute, fellowship-trained physicians Dr. Asim Khan and Dr. Daniel Ryklin are getting athletes back to their sport in 6-8 weeks using amniotic stem cell therapy—without surgery, without general anesthesia, and without missing your entire season.

Are You the Right Fit for This Treatment?

Not everyone needs surgery for a rotator cuff tear. In fact, if you’re reading this and nodding along to these situations, you’re likely an ideal candidate for amniotic stem cell therapy:

You have a partial tear (less than 50% thickness) that’s painful but not completely torn through. You’ve tried physical therapy for 6-8 weeks but still can’t serve, throw, or swim without pain. Most importantly, you can’t afford to be out of commission for the 4-6 months that surgery requires.

Dr. Khan, who has provided medical coverage at NCAA events and worked with athletes at Arizona State University, sees this scenario constantly. These are athletes between 30 and 55 who stay active, compete regularly, and define themselves by their sport. Sound familiar?

The Science That Actually Heals Your Shoulder

Here’s what sets Arizona Pain and Spine Institute apart from other clinics claiming to offer “stem cell” treatments. They use amniotic fluid cells sourced from a US-based Arizona company that follows stringent FDA protocols. These cells come from scheduled C-sections with full donor consent—no embryonic tissue, no ethical concerns, just pure healing potential.

The process is surprisingly straightforward:

First, the amniotic fluid naturally contains mesenchymal stem cells and growth factors that act like fertilizer for your body’s repair system.

Second, when Dr. Ryklin or Dr. Khan inject these cells directly into your torn rotator cuff using ultrasound guidance for precision, your body immediately begins reducing inflammation—you’ll feel this within days.

Third, over the next few weeks, these cells stimulate your body to produce new, healthy tissue that actually repairs the torn fibers, rather than just masking the pain with cortisone.

Finally, the treatment promotes proper collagen formation and new blood vessel growth, creating stronger, more flexible tissue than you had before the injury.

The amniotic tissue they use undergoes rigorous safety protocols. It’s manufactured in an AATB-accredited facility, tested for all transmittable diseases, and specially prepared with amnion only (no chorion) to eliminate any risk of rejection.

Real Timeline Comparison: Getting Back to Your Sport

Let’s talk about what really matters—when you can play again. Here’s the honest comparison between amniotic stem cell therapy and surgery:

With Amniotic Stem Cell Therapy at Arizona Pain & Spine

The entire injection takes 5-15 minutes in the office. You walk out the same day.

Days 1-3, you’re resting with ice, maybe some soreness at the injection site—nothing compared to surgical pain. By the end of week one, you’re already doing gentle range-of-motion exercises.

Weeks 2-3 mark a turning point. You start physical therapy and many athletes begin light training. This is when surgery patients are still completely immobilized in a sling.

By weeks 4-6, you’re progressing back to sport-specific activities. Your tennis serve is coming back. Your swim stroke feels natural again. You’re actually doing your sport, not just dreaming about it.

Most athletes return to full competition by weeks 6-8.

With Arthroscopic Surgery

Day one requires general anesthesia and actual surgery. Even though it’s “minimally invasive,” it’s still surgery.

For the first 6 weeks, you’re stuck in a sling with zero active movement. Your muscles are atrophying. Your conditioning is gone. While your competitors are training, you’re just trying to sleep comfortably.

Months 3-4, you finally start basic strengthening. You’re nowhere near your sport yet. By months 4-6, if everything goes perfectly, you might gradually return to sports activities.

The reality? Full return to competition rarely happens before 6 months, and that’s if you’re lucky enough to avoid the 20-30% re-tear rate.

When PRP Isn’t Enough (But Surgery Is Too Much)

You might be wondering about PRP since it’s cheaper and you’ve heard about pro athletes using it. Here’s the honest breakdown:

PRP works well for minor tears under 1cm and tendinitis. Recovery is quick—2 to 4 weeks—but the success rate for partial tears is only 60-70%. It’s like putting a band-aid on the problem.

Amniotic stem cell therapy bridges the gap. It handles partial tears up to 50% thickness with a 75-85% improvement in function. More importantly, it promotes actual tissue regeneration, not just temporary improvement. The 4-8 week recovery timeline lets you maintain your fitness while healing.

Surgery remains necessary for complete tears, tears larger than 3cm, or when there’s significant muscle atrophy. As Dr. Khan says, “We’re not anti-surgery. We’re pro-athlete. If surgery gives you the best chance at returning to your sport, that’s what we’ll recommend.”

A Phoenix Tennis Player’s Story

Mark, a 42-year-old competitive tennis player from Scottsdale, faced this exact decision when MRI revealed a 40% thickness rotator cuff tear. Surgery would mean missing the entire season.

“Dr. Khan explained how the amniotic stem cells would actually heal my tear, not just mask the pain,” Mark recalls. “The injection took maybe 10 minutes. By week three, I was hitting light serves. At six weeks, I played my first match. Now, four months later, my shoulder feels stronger than it has in years.”

This isn’t unusual. Since 2016, Dr. Khan and Dr. Ryklin have refined their regenerative medicine approach, helping hundreds of athletes avoid surgery and return to their sports faster than they thought possible.

The FastTrack System: Because Athletes Can’t Wait

Insurance approvals, scheduling delays, waiting for authorizations—none of that works when your season is on the line. That’s why Arizona Pain and Spine Institute created FastTrack for cash-pay patients.

Here’s how it works:

1. Same-week consultation: Call Monday, be seen by Wednesday
2. Immediate imaging review: Bring your MRI or get one done that day
3. Treatment that visit: If you’re a candidate, get your injection immediately
4. Transparent pricing: Know your costs upfront, no insurance surprises
5. Follow-up included: Your recovery is monitored without additional fees

Athletes travel from across Arizona and internationally—”from 1 mile to 8,000 miles away”—specifically for this expertise and efficiency.

Why These Doctors, Why This Clinic?

Dr. Asim Khan and Dr. Daniel Ryklin aren’t just pain doctors who added stem cells to their menu. They’re double board-certified in Physical Medicine and Rehabilitation and Pain Management, fellowship-trained in interventional pain management, with over a decade focusing on regenerative therapies.

Dr. Khan has worked directly with NCAA athletes at University of Illinois Chicago and Arizona State University. Dr. Ryklin specializes in biomechanical and functional assessment—he understands how athletes move and what they need to perform.

They’ve published research in peer-reviewed journals. They’ve helped hundreds of patients avoid surgery. Most importantly, they understand that for athletes, returning to sport isn’t just about pain relief—it’s about performance, confidence, and identity.

Your Next Move

You have three options right now:

1. Keep doing what you’re doing and hope it gets better (it probably won’t)
