Why Meniscus Tears Are So Challenging
The meniscus acts like a cushion and stabilizer inside your knee, absorbing shock and distributing load evenly. When it’s injured – whether from sports, twisting, or gradual wear – it can lead to pain, swelling, and stiffness that limits daily life.
Because the meniscus has a limited blood supply, many tears don’t heal well on their own. Traditional care such as rest, NSAIDs, or even arthroscopic surgery may offer short-term relief, but these approaches do not restore healthy meniscus tissue.
What New Research Shows
A 2025 meta-analysis published in The Orthopaedic Journal of Sports Medicine evaluated 18 randomized controlled trials (1,143 patients) comparing platelet-rich plasma (PRP) with placebo or standard care.
The authors reported that PRP was associated with:
- clinically meaningful reduction in pain (VAS)
- improved knee function (Lysholm and KOOS scores)
- a ~74% lower failure rate (fewer patients ultimately needing surgical escalation)
- no increase in complications compared to controls
Importantly, these benefits were observed in both younger and older adults, whether or not early arthritis was present (1).
This analysis supports that PRP may reduce pain and support the body’s natural repair process in meniscus injuries.
Why Steroids, NSAIDs, and Surgery Often Fall Short
- Corticosteroid injections may temporarily mask pain, but repeated dosing can weaken cartilage and soft tissue.
- NSAIDs block inflammatory pathways that are part of the body’s healing response, and long-term use carries known systemic risks.
- Partial meniscectomy (surgery) removes damaged meniscal tissue, reducing the knee’s cushion and increasing stress on cartilage, which may accelerate joint degeneration.
Several large randomized trials have even shown no significant long-term difference between meniscus surgery and conservative care or placebo surgery in terms of pain and function outcomes.
PRP: A Regenerative, Evidence-Supported Option
PRP uses your own platelets, concentrated and delivered precisely under image guidance, to provide growth factors that support cell repair, collagen production, and a more favorable joint environment.
At New Regeneration Orthopedics, we perform Regenexx-standard PRP and biologic procedures designed to optimize platelet concentration and biologic activity. Our approach targets the injured tissue directly using ultrasound or fluoroscopic guidance.
Ready to Explore Non-Surgical Options?
If you’re dealing with a meniscus tear or ongoing knee pain, our physicians can help determine whether PRP is a good option for you. The goal: support reduced pain and improved function without rushing to surgery.
