Knee Arthritis

Most patients are handed a two-step roadmap: cortisone until it stops working, then replacement. The knee actually has more treatment options than any other arthritic joint, including hyaluronic acid, regenerative medicine, and nerve procedures that can delay surgery.

IN SHORT

Knee arthritis has more treatment options than any other joint arthritis. At PHI in Beverly Hills, board-certified physicians Dr. Faisal Lalani and Dr. Nadiv Samimi offer image-guided injections, hyaluronic acid, regenerative medicine, and genicular nerve procedures to relieve pain and help many patients delay or avoid knee replacement.

More Options Than Cortisone or Surgery

Knee arthritis is one of those diagnoses where most patients have been told there are essentially two paths: cortisone shots until you cannot get any more, then knee replacement when you cannot take it anymore. That is a frustrating roadmap, particularly if you hike, play tennis, golf, dance, run, or just want to move freely without your knee dictating the terms.

The reality is that knee arthritis has more treatment options than any other joint arthritis. Hyaluronic acid injections FDA-approved specifically for the knee. Multiple regenerative approaches with robust evidence. Nerve-targeted procedures that can provide pain relief lasting up to two years from a single treatment. Combinations that work better than any single approach alone. The right path depends on your stage of arthritis, what you have already tried, and what you actually want to do with your knee. Most patients have more options than they have been told.

What Knee Arthritis Actually Is

Your knee is a hinge joint where the femur, tibia, and patella meet, with cartilage covering the ends of the bones and the meniscus providing additional cushioning. Knee arthritis develops when this cartilage wears down. The most common form is osteoarthritis, related to age, wear, prior injury, or genetics. Inflammatory arthritis affects the knee differently and is coordinated with rheumatology, and post-traumatic arthritis develops years after a significant injury.

As cartilage wears, bone-on-bone contact develops gradually, inflammation increases, bone spurs form, and the joint’s natural lubricating fluid often becomes less effective. The result is the symptoms most patients experience: pain, stiffness, swelling, limited motion, and difficulty with specific activities.

What Stage Is Your Knee Arthritis?

Knee arthritis exists on a spectrum, and treatment recommendations vary significantly by stage. Early-stage arthritis involves intermittent pain mostly with activity and imaging showing some cartilage thinning but joint space largely preserved; regenerative medicine is often particularly worth exploring at this stage. Moderate arthritis involves more consistent pain, more noticeable stiffness, occasional swelling, and moderate joint space narrowing, with hyaluronic acid often becoming relevant alongside regenerative options. Advanced arthritis involves significant daily pain, substantial movement limitation, frequent swelling, and severe narrowing or bone-on-bone contact; non-surgical options including genicular nerve procedures are still possible, but knee replacement often becomes appropriate for patients seeking to recover their function. Many patients are surprised by the range of options that fit their specific stage.

How PHI Treats Knee Arthritis

Treatment begins with a comprehensive evaluation of your symptoms, activity goals, alignment, imaging, and where you fall on the arthritis spectrum. Based on that, options at PHI include:

Image-guided knee injections with cortisone for fast relief from inflammation, with the cumulative effects of repeated cortisone discussed honestly. Hyaluronic acid (Orthovisc), FDA-approved specifically for knee osteoarthritis, which replenishes the joint’s natural lubricating fluid with relief that develops gradually but typically lasts longer than cortisone. PRP therapy, which has a strong evidence base for knee osteoarthritis with significant pain relief and functional improvement at 6 and 12 months. A2M therapy, which neutralizes cartilage-destroying enzymes and is particularly relevant for early-to-moderate arthritis. Stem cell therapy for moderate to severe arthritis or after PRP. Exosome therapy within comprehensive protocols. Genicular nerve blocks, which both diagnose and provide therapeutic relief by targeting the nerves carrying pain signals from the knee. And genicular radiofrequency ablation, which ablates those nerves and can provide durable pain relief from a single procedure, particularly valuable for patients trying to delay or avoid knee replacement, those who are not surgical candidates, or those with persistent pain after knee replacement. When knee replacement is the right next step, we coordinate with orthopedic specialists.

When to See Someone

Consider professional evaluation when your knee pain has lasted more than four to six weeks without improvement, when it interferes with activities you want to do, when you are avoiding exercise because of it, when you want to understand non-surgical options, when you want to delay or avoid knee replacement, or when conservative treatments have not provided adequate relief.

Seek prompt evaluation if you experience sudden severe knee pain following an injury, inability to bear weight on the leg, significant knee swelling, warmth, or redness, or knee pain accompanied by fever or feeling unwell.

Why PHI for Knee Arthritis

i.

Two board-certified pain physicians

Dr. Faisal Lalani and Dr. Nadiv Samimi both trained in interventional pain at Cedars-Sinai, with specific expertise across the full range of knee arthritis treatments.

ii.

Image-guided technique on every injection

Knee injections without imaging are less accurate. PHI uses image guidance in our surgery center at 455 N Roxbury Drive, Suite B, which significantly improves accuracy and effectiveness.

iii.

The full range under one roof

Many practices offer cortisone and refer everything else out. PHI offers cortisone, hyaluronic acid, the full regenerative menu, genicular blocks, and genicular ablation.

iv.

Genicular ablation expertise

Genicular radiofrequency ablation is one of the most clinically valuable recent advances for moderate to severe knee arthritis, providing durable relief from a single procedure. PHI offers it as part of comprehensive knee care.

v.

Honest framing

Each treatment fits different situations. We are frank about cumulative cortisone effects, realistic expectations for hyaluronic acid, the timeline for regenerative options, and when surgical evaluation makes sense.

vi.

Concierge, coordinated care

Single-physician continuity from consultation through treatment and return to activity. Patients receive clear guidance and transparent pricing at consultation.

Frequently Asked Questions

This depends on your stage of arthritis, treatment history, goals, and imaging. Cortisone is fast but cumulative. Hyaluronic acid is FDA-approved for the knee and lasts longer but takes longer to develop. PRP and other regenerative options work over a longer horizon and address tissue rather than only inflammation. Genicular ablation provides durable relief by targeting nerves. Each fits different situations, and we help you understand which fits yours.
