How Long Does PRP Take to Work for Knee or Shoulder Pain?

Posted on: August 3rd, 2026 by Connor Ziegler

A Real-Life Patient Scenario

A common patient we see is a 58-year-old active adult with chronic knee or shoulder pain who wants to stay active but is not ready for surgery.

They’ve spent years doing the “right things”—physical therapy, anti-inflammatory medications, activity modification, and even cortisone injections. For a while, these treatments helped. But the pain keeps coming back. Walking the golf course, playing tennis, lifting weights, or even sleeping comfortably has become increasingly difficult.

Eventually, they’re told: “You may need surgery.”

The Question Many Patients Ask

“Is there anything I can do to reduce pain and improve function before considering surgery?”

For many active adults, this is where regenerative orthopedic treatments like PRP (platelet-rich plasma) and bone marrow aspirate (BMA) enter the conversation.

Understanding the Problem: Why Knee and Shoulder Pain Persist

What’s Causing the Pain?

Knee and shoulder pain in adults aged 40–70 is often related to:

  • Mild to moderate arthritis
  • Degeneration of cartilage
  • Partial tendon or ligament tears (rotator cuff, meniscus, etc.)
  • Chronic inflammation

These conditions don’t typically result from one injury—but rather from years of wear and tear combined with decreased healing capacity over time.

Why Does It Develop?

As we age:

  • Blood supply to tissues decreases
  • Healing slows down
  • Micro-injuries accumulate
  • Cartilage becomes thinner and less resilient

This leads to a cycle of pain → inflammation → limited activity → further degeneration.

Traditional Treatments—and Their Limitations

Most patients have already tried:

  • Physical therapy
  • Anti-inflammatory medications
  • Cortisone injections

While these can help temporarily, they often:

  • Do not address underlying tissue damage
  • Provide only short-term relief
  • May lose effectiveness over time

Why Many Active Adults Want to Avoid Surgery

Surgery—whether knee replacement or rotator cuff repair—is sometimes necessary. However, many patients prefer to delay or avoid it because:

  • Recovery can take months
  • There are risks and downtime
  • It may limit future activity levels
  • It’s a major life disruption

This has led many patients to explore modern regenerative options.

Introducing Regenerative Orthopedics: PRP and BMA

What Is PRP (Platelet-Rich Plasma)?

PRP is created from your own blood. It contains a high concentration of platelets, which are rich in growth factors that support healing.

When injected into an injured or degenerated area:

  • It helps reduce inflammation
  • It stimulates natural tissue repair
  • It promotes a more favorable healing environment

What Is Bone Marrow Aspirate (BMA)?

BMA is obtained from your own bone marrow and contains:

  • Stem cells
  • Growth factors
  • Healing cells

These components work together to:

  • Support tissue regeneration
  • Enhance healing in more advanced conditions
  • Address deeper structural issues

What Does the Research Suggest?

PRP: What Patients Should Know

Research suggests that PRP may:

  • Improve pain and function in knee arthritis and tendon injuries
  • Provide longer-lasting relief compared to cortisone in some cases
  • Work best in mild to moderate conditions

Patients often report:

  • Gradual improvement over weeks
  • Continued progress over several months

BMA: What Patients Should Know

BMA is often considered when:

  • Arthritis is more advanced
  • PRP alone may not be sufficient
  • There is more significant tissue damage

Studies suggest BMA may:

  • Support more robust healing
  • Improve pain and function in selected patients
  • Be beneficial in complex or chronic cases

So… How Long Does PRP Take to Work?

This is one of the most important—and most common—questions.

General Timeline for PRP

  • First 1–2 weeks:
    Mild soreness or inflammation (normal healing response)
  • 2–6 weeks:
    Early improvement in pain and mobility
  • 6–12 weeks:
    More noticeable functional gains
  • 3–6 months:
    Continued improvement as healing progresses

Key Takeaway

PRP is not an instant fix like cortisone.
It is designed to stimulate your body’s natural healing, which takes time.

💬 “Most patients begin to notice improvement within a few weeks, with continued progress over several months.”

You may be a candidate if you:

  • Have mild to moderate arthritis
  • Have partial tendon or ligament injuries
