Most orthopedic guidelines recommend 3 - 6 months of consistent conservative treatment before evaluating surgery. Some patients benefit from longer trials, especially if they're seeing gradual improvement.

Physical therapy can significantly reduce pain and improve function, but it cannot reverse cartilage damage. However, it may eliminate the need for surgery in many cases.

Corticosteroid injections are generally safe when spaced 3+ months apart, typically limited to 3 - 4 injections per year. Your doctor will monitor your response and adjust accordingly.

Most patients return to light activities within 6 weeks and resume normal activities within 3-6 months. Full recovery and maximum benefit may take up to one year.

Severe arthritis may eventually require surgery, but even patients with advanced OA can benefit from 6 - 12 months of conservative care to clarify whether surgery is truly necessary and to optimize their health before surgery. This period allows time to explore all non-surgical options, strengthen surrounding muscles, and ensure you're deciding a place of informed confidence rather than pain-driven urgency.

Partial (unicondylar) replacement addresses arthritis in one compartment of the knee and preserves more bone. Total replacement addresses the entire joint. Partial replacement is suitable only for isolated, single - compartment arthritis. Because partial replacements preserve more of your natural knee structure, they may offer slightly better long - term outcomes for carefully selected patients, though they're appropriate for only about 10 - 15% of candidates.

Total knee replacement typically costs between $35,000-$60,000, which includes surgeon fees, facility costs, and implants. Insurance coverage varies; check with your provider about out-of-pocket costs. Many New Jersey facilities offer financial counseling to help patients understand their actual expenses after insurance, and some offer payment plans for remaining balances.

Genicular artery embolization (GAE) and platelet - rich plasma (PRP) are emerging treatments showing promise for some patients. Long-term data is still limited. Discuss candidacy with your surgeon. While early results are encouraging, these options work best for patients with mild to moderate arthritis and should be considered as part of a comprehensive conservative care strategy rather than standalone solutions.

Modern implants last 15 - 20+ years. Younger patients may eventually need revision surgery. Older patients often have implants lasting their lifetime. Revision surgery is more complex than the initial procedure, which is why younger patients should carefully weigh the long - term implications of knee replacement and ensure conservative options have been genuinely exhausted.

Many patients return to low - impact activities like walking, swimming, and cycling. High-impact sports like running or basketball are generally not recommended. Most orthopedic surgeons encourage patients to stay active within these guidelines, as appropriate exercise strengthens the knee and extends implant longevity. Your surgeon can provide specific activity recommendations based on your implant type and overall health.

For patients with bone-on-bone arthritis who have genuinely exhausted 6 - 12 months of conservative options, knee replacement delivers 85 - 90% patient satisfaction. However, studies suggest 20 - 30% of knee replacements may be performed before alternatives have been fully explored. A second opinion confirms whether you've reached that threshold and helps ensure you're making a decision based on complete information rather than incomplete conservative care.
