PRP (Platelet-Rich Plasma) injections have become a game-changer in managing chronic knee pain caused by arthritis, injuries, and tendon issues. While the treatment itself is quick and non-surgical, one of the most common patient concerns is: “How long is the recovery time after a PRP injection for knee pain?”
This blog explains what to expect in the days, weeks, and months following the procedure—and how to get the best results.
Immediate Recovery: First 24–48 Hours
After receiving a PRP injection, you may feel mild discomfort or soreness at the injection site. This is normal and part of your body’s natural healing response.
What to Expect:
- Mild swelling or redness
- Warmth around the knee
- Temporary stiffness
- Occasional light bruising
Care Tips:
- Rest the knee as much as possible
- Avoid high-impact activities
- Ice the area if needed
- Do not take NSAIDs (like ibuprofen) unless advised, as they can interfere with platelet activity
Short-Term Recovery: First 1–2 Weeks
In this phase, inflammation decreases and healing begins. Most patients report a gradual reduction in pain and improved mobility by the end of the first week.
Activities You Can Start:
- Light walking
- Daily movements without strain
- Gentle stretching exercises as advised
You may also begin physiotherapy under professional guidance to restore joint flexibility.
Mid-Term Recovery: 3–6 Weeks
This is the stage where the actual healing benefits of PRP start to show. By the 4th to 6th week, most patients experience noticeable improvements in:
- Joint stiffness
- Knee strength
- Swelling reduction
- Pain during movement
If multiple sessions are planned, your doctor may schedule the second PRP injection around this time.
Long-Term Recovery: 2–3 Months
Between 8 to 12 weeks, patients typically reach peak benefits from their PRP therapy. This includes:
- Enhanced cartilage repair (especially for early-stage arthritis)
- Improved knee function
- Longer periods without pain
For many, the results last 6 to 12 months or more, depending on age, severity, and lifestyle.
What Can Delay PRP Recovery?
Several factors can slow down the healing process:
- Skipping post-injection care
- Returning too soon to intense physical activity
- Underlying metabolic conditions (e.g., diabetes, obesity)
- Smoking or poor diet
Always follow your orthopedic doctor’s instructions for the best outcome.
How to Maximize Your PRP Recovery?
- Stay consistent with prescribed physiotherapy
- Focus on low-impact exercises like cycling or swimming
- Maintain a healthy weight to reduce joint stress
- Follow a diet rich in protein and anti-inflammatory foods
- Attend all follow-up appointments
