Understanding Orthobiologics & PRP
An evidence-based guide for active adults and athletes — what these therapies really are, what they can realistically do, and how they fit a bigger plan.
If you’ve researched alternatives to surgery, you’ve likely met the terms PRP, stem cells, regenerative medicine, biologics, and orthobiologics — surrounded by a tremendous amount of confusion. Some sources claim these therapies regrow nearly any tissue and reverse arthritis. Others dismiss them as unproven. The truth is more nuanced.
“Orthobiologics are neither magic nor a hoax. They are tools that may help the body’s natural healing — in the right patient, for the right condition, at the right time.”
What are orthobiologics?
Biologic substances used to support healing in musculoskeletal tissues — tendons, ligaments, muscles, cartilage, and joints. Many are derived from your own body. Platelets are central: beyond clotting, they release growth factors and signaling molecules that help coordinate inflammation, repair, and blood-vessel formation. PRP concentrates those natural healing signals and delivers them where they’re needed.

The two biggest misconceptions
What the evidence shows
Chronic, degenerative tendon disorders — tennis elbow, patellar, Achilles, gluteal, and certain rotator cuff conditions — are among the best-studied candidates.
May improve pain and function in mild-to-moderate arthritis. Strongest for the knee, with growing evidence in hip and shoulder. Less predictable in advanced disease.
May support joint health and symptoms, but current evidence does not support claims that PRP reliably regrows large amounts of cartilage or reverses advanced degeneration.
Who is a good candidate?
Mild-to-moderate arthritis
Chronic tendon injuries
Seeking alternatives before surgery
Committed to rehab and recovery
Complete tendon rupture
Certain severe structural injuries
Expecting immediate results
Unwilling to participate in rehab
PRP is rarely a stand-alone solution — an honest discussion about expectations is one of the most important parts of the evaluation.
What to expect after treatment
PRP is not a steroid injection — relief is rarely immediate, and a temporary soreness or mild flare in the first days is often part of the normal healing response. Recovery follows a gradual arc:
The Path Forward
Orthobiologics are never a magic solution — they are one tool within a larger strategy. Every plan follows the same arc:
“The goal is not false hope. The goal is informed hope.”
