Understanding Your Options
When knee osteoarthritis starts affecting your daily life, you face an important choice. Should you try conservative treatments first, or is it time to consider knee replacement surgery?
This decision affects millions of Americans each year. The good news is that most people don’t need to rush into surgery. Conservative treatments work well for many patients and can delay or even eliminate the need for knee replacement.
This guide walks you through both paths so you can make an informed decision with your doctor.
What Are Conservative Treatments?
Conservative treatments are non-surgical options that help manage knee arthritis symptoms. They include:
- Physical therapy and exercise
- Over-the-counter pain medications
- Cortisone injections
- Gel injections (hyaluronic acid)
- Knee braces and supports
- Weight management
- Lifestyle changes
These treatments focus on reducing pain, improving function, and slowing arthritis progression without surgery.
The Conservative Treatment Pathway
Most doctors follow a step-by-step approach. You start with the simplest options and move to more advanced treatments if needed. This is called the treatment ladder.
Step 1: Physical Therapy and Exercise
Physical therapy is often the foundation of conservative care. Strong leg muscles take pressure off your knee joint. Many patients see meaningful improvement within 6-8 weeks.
Step 2: Over-the-Counter Medications
Talk to your doctor before long-term use. NSAIDs can cause stomach and kidney problems in some people.
Step 3: Cortisone Injections
When pills and PT aren’t enough, cortisone injections can help. These powerful anti-inflammatory medications are injected directly into your knee joint.
What to expect:
- Relief often begins within 2-3 days
- Effects typically last 4-8 weeks
- Can be repeated 3-4 times per year
- Quick office procedure (5-10 minutes)
Cortisone works best for inflammation flare-ups. It’s not a long-term solution, but it can provide meaningful short-term relief.
Step 4: Gel Injections (Viscosupplementation)
Gel injections, also called hyaluronic acid injections, restore the natural lubricating fluid in your knee. Healthy knees have this fluid. Arthritis depletes it.
How gel injections help:
Duration: Relief typically lasts 6-12 months and can be repeated as needed. Many patients use gel injections successfully for years.
Step 5: Bracing and Support
Knee braces can help by:
- Shifting weight away from damaged areas
- Providing stability during activity
- Reducing pain during exercise
Unloader braces work especially well for arthritis affecting one side of the knee.
Surgical Options
When conservative treatments no longer provide adequate relief, surgery may be appropriate. Understanding your surgical options helps you make an informed choice.

Head-to-Head Comparison
| Factor | Conservative Treatment | Knee Replacement Surgery |
|---|---|---|
| Recovery Time | Hours to days | 3-6 months |
| Hospital Stay | None (outpatient) | 1-3 days |
| Time Off Work | Minimal | 6-12 weeks |
| Anesthesia | Local or none | General or spinal |
| Total Cost | $500-2,000 per treatment | $30,000-50,000+ |
| Out-of-Pocket | $0-500 typical | $3,000-10,000 typical |
| Success Rate | 60-80% report improvement | 90%+ report improvement |
| How Long Results Last | 6-12 months (repeatable) | 15-20 years |
| Risk Level | Very low | Moderate |
| Reversibility | Fully reversible | Permanent |
| Best For | Mild-moderate OA (stages 1-3) | Severe OA (stage 4) |

The “Surgery Delay” Research
What 182,000 Patients Reveal
A landmark study published in the Journal of Arthroplasty followed 182,022 Medicare patients with knee osteoarthritis. The findings were striking:
This is the largest study ever conducted on this question. It provides strong evidence that gel injections can meaningfully delay knee replacement for appropriate candidates.
Why Delaying Surgery Can Be Smart
-
Technology improves. Knee replacement techniques and implants continue advancing. A replacement done in 5 years may be better than one done today.
-
Implants have a lifespan. Most last 15-20 years. If you’re 55 and get a replacement now, you may need revision surgery at 70-75. Delaying can mean one surgery instead of two.
-
Avoid surgical risks. Every surgery avoided is risk avoided. Blood clots, infection, and anesthesia complications are real concerns.
-
Lower costs. Years of conservative treatment typically cost less than one surgery.
-
Maintain independence. No 3-6 month recovery period means you stay active and self-sufficient.
”Am I Too Young for Surgery?”
This is one of the most common questions people ask. The answer depends on several factors.
Age Considerations for Knee Replacement
Under 55:
- Most surgeons recommend exhausting conservative options first
- Implant lifespan means you’ll likely need revision surgery
- Younger patients tend to be more active, which increases implant wear
- Conservative treatments can often “bridge” you to an older age
55-65:
- Middle ground where both approaches are reasonable
- If quality of life is severely impacted and conservative treatments failed, surgery is appropriate
- Consider trying gel injections to delay 5-10 years if possible
Over 65:
- Age alone isn’t a barrier to successful surgery
- Overall health matters more than calendar age
- If conservative treatments haven’t worked, surgery can restore quality of life
Key point: Your arthritis severity, symptom impact, and response to conservative treatments matter more than your age alone.
Many patients successfully use conservative treatments to delay surgery by years, even when they’ve been told their only option is a new knee. While surgery is the right choice for some people, it’s not always as urgent as it may seem.

Making the Right Decision for You
The choice between conservative treatment and surgery isn’t one-size-fits-all. Here’s a framework to guide your thinking:
Decision Framework
| Factor | Favors Conservative | Favors Surgery |
|---|---|---|
| Arthritis stage | Mild-moderate (1-3) | Severe (4) |
| Quality of life impact | Moderate | Severe |
| Previous conservative treatments | Haven’t tried all | Failed multiple |
| Recovery time available | Limited | Can commit 3-6 months |
| Overall health | Any | Good surgical candidate |
| Age | Younger (delay implant) | Any with good health |
| Risk tolerance | Risk-averse | Accepts surgical risks |
The Path Many Patients Take
Most patients don’t choose one or the other immediately. Instead, they follow a progressive path:
This progressive approach lets you benefit from conservative care while keeping surgery available when truly needed.
The Bottom Line
Key Takeaways
The most important step is having an honest conversation with your healthcare provider about YOUR specific situation. Share your symptoms, your goals, and your concerns. Together, you can find the right path forward.
