Knee replacement is one of the most commonly performed surgeries in the United States — and for many patients, it’s the right choice. But it is not the only choice, and it is not without consequence. Recovery takes months. The implant has a lifespan. And the surgery carries real risks, particularly for patients with other health conditions.
If you’ve been told you need a knee replacement, or if you’re worried you’re heading in that direction, this article is worth reading carefully. Dr. Scheinberg has performed knee replacement surgeries throughout his 40-year career. He knows when they’re necessary. He also knows that a meaningful number of patients are told they need one before they’ve genuinely exhausted less invasive options.
The Honest Case for Orthobiologics
Orthobiologics — treatments like PRP and BMAC that use concentrated materials from your own body to promote healing — are not a guaranteed alternative to joint replacement. Anyone who tells you otherwise isn’t being straight with you. What they represent is a legitimate and increasingly well-studied option for delaying or potentially avoiding replacement surgery in appropriate candidates.
The research is real. A 2024 study published in *Scientific Reports* followed patients with severe knee arthritis (Kellgren-Lawrence Grade III and IV — the most advanced stages) for four years after BMAC injections. Not a single patient required knee replacement during that follow-up period. Pain scores and functional measures improved significantly. This is not anecdote — it is Level 1 clinical evidence.
Similarly, multiple systematic reviews of PRP for knee osteoarthritis have shown meaningful improvements in pain and function at 6 and 12 months, consistently outperforming hyaluronic acid (“gel injections”) and often performing comparably to more invasive options.
Who Is a Candidate
Dr. Scheinberg’s philosophy is “biologic first” — which means that for patients with moderate to severe arthritis, he wants to thoroughly evaluate whether a biologic protocol can provide adequate relief before recommending surgery.
The strongest candidates for orthobiologics as an alternative to knee replacement are patients who:
- Have moderate arthritis (Kellgren-Lawrence Grade II or III) with remaining joint space
- Have active symptoms but are not bone-on-bone in all compartments
- Are in generally good health and able to participate in rehabilitation
- Have not yet tried PRP or BMAC (or tried poorly administered versions of these)
- Have a strong desire to preserve their natural anatomy
The more challenging cases — patients with Grade IV arthritis in all compartments, significant varus or valgus deformity, or BMI factors that accelerate mechanical deterioration — may still benefit from biologics, but the expectations need to be realistic and the conversation honest. Dr. Scheinberg has decades of surgical experience to help patients understand exactly where they stand.
What “Biologic First” Means in Practice
At the Scheinberg Clinic in Santa Barbara, patients do not arrive and immediately receive an injection. The first step is a surgical-grade assessment: reviewing your imaging, understanding your history, evaluating your biomechanics, and making an honest determination of what is likely to help you.
For many patients with knee arthritis, the protocol begins with PRP — a series of high-concentration platelet injections that reduce inflammation, stimulate cartilage support, and often provide significant pain relief. For patients with more advanced degeneration, BMAC is added to the protocol, either alone or in combination with PRP. The combined approach provides the broadest regenerative environment possible.
Patients also work on the factors that influence knee health — weight, muscle conditioning, activity modification — because biologics work best when the mechanical environment of the joint is also being optimized.
What to Expect
Results vary, and intellectual honesty requires saying that. Some patients experience dramatic improvement — returning to hiking, golf, tennis, or other activities they had set aside. Others see moderate improvement that allows them to defer surgery by years. A smaller percentage do not respond adequately and ultimately proceed to replacement.
What Dr. Scheinberg offers is the surgical judgment to tell the difference. He has performed knee replacements. He knows when they’re the right answer. His commitment to biologic-first care is not ideology — it’s a genuine clinical assessment that every patient deserves to have before undergoing major surgery.
If you’re on the Central Coast, in Bakersfield, or willing to travel to Santa Barbara for a serious evaluation, the conversation starts with an honest look at your imaging and your goals.
