Orthobiologics for Knee Pain: What Can Be Treated and What to Expect
The knee is one of the most complex and load-bearing joints in the body, which makes it one of the most common sources of orthopedic pain — and one of the most frequent reasons patients come to Albano Clinic seeking an alternative to surgery.
Here’s a breakdown of the knee conditions that respond well to orthobiologic treatment, and what the evidence shows.
Osteoarthritis
Knee osteoarthritis — the gradual breakdown of cartilage between the femur and tibia — is the most common indication for both PRP and bone marrow concentrate. Studies have shown significant reductions in pain and improvements in function in patients with grades 1–3 osteoarthritis. Grade 4 (bone-on-bone) responds less predictably, though treatment can still provide meaningful relief and may delay or reduce the need for replacement.
Steroid injections, by contrast, provide temporary symptom suppression and have been shown to cause further cartilage degradation with repeated use — the opposite of what you want in a degenerative condition.
Meniscal Tears
The meniscus acts as the knee’s shock absorber. Standard surgical treatment — partial meniscectomy — involves trimming away torn tissue, leaving less cartilage than before the surgery. Post-meniscectomy data shows 100% increased contact stress on the inner knee and 300% on the outer knee, with six times the risk of future osteoarthritis and three times the risk of eventual total knee replacement.
Orthobiologic treatment aims to preserve the meniscus rather than reduce it, supporting tissue repair and reducing the degenerative cascade that follows meniscectomy. For appropriate tears, this is a fundamentally different trajectory.
Patellofemoral Syndrome
Softening or deterioration of the cartilage behind the kneecap — sometimes called runner’s knee or jumper’s knee — responds well to PRP, particularly when caught before significant structural loss has occurred.
ACL and MCL Injuries
Complete ACL tears require surgical reconstruction. Partial ACL tears are a different situation — many can be treated successfully with PRP and structured physical therapy. MCL tears, including more severe ones, are generally good orthobiologic candidates and often do not require surgery at all.
PRP is also commonly used as an adjunct to ACL surgery to improve graft integration and accelerate recovery.
Patellar and Quadriceps Tendinopathy
Tendinopathy that hasn’t resolved with rest, physical therapy, and conservative management responds well to PRP. Growth factors delivered directly to the tendon support collagen remodeling and tissue repair.
What Treatment Looks Like
Blood is drawn and processed in a centrifuge to concentrate platelets and growth factors (PRP), or bone marrow is harvested from the posterior pelvis for more advanced cases. Fat-derived cells may also be used depending on injury severity and patient anatomy.
All injections are performed under real-time musculoskeletal ultrasound guidance for precise placement. Most patients experience some soreness and swelling for several days post-procedure — this is the intended inflammatory healing response. Significant improvement typically begins within four to eight weeks, with continued progress through four to six months.
Physical therapy beginning approximately one week post-procedure is a standard part of the protocol and meaningfully affects outcomes.
