Postoperative Recovery After Knee Arthroscopy
First 24 Hours After Surgery
- The knee is bandaged; drainage tube may be removed
- Mild pain and swelling are common
- Ice application and elevation are crucial
- No weight bearing; crutches or a walker are used
- Blood thinners may be prescribed depending on your surgeon
Week 1: Early Recovery Phase
- Ice and elevation continue to reduce swelling and pain
- Gentle passive range of motion exercises may begin
- Light daily activities can be resumed with care
- Stitches are usually removed around day 7–10
- Physical therapy typically starts this week
Weeks 2–4: Regaining Mobility
- Physical therapy intensifies
- Strengthening exercises, especially for the quadriceps, are introduced
- Stairs and short walks may be allowed
- Knee bending and extension improve significantly
- Running or deep squats are still restricted
Weeks 4–8: Rebuilding Strength
- Muscle mass and balance training become the focus
- Low-impact activities like cycling or swimming may begin
- Knee weight-bearing tolerance increases
- Minimal to no pain during daily activities
- Assessment for return to sport (based on type of procedure)
Week 8 and Beyond
- Full range of motion typically returns
- Gradual return to moderate physical activity (e.g., jogging, squats)
- Return to sports may begin around 3 months
- For ACL reconstructions, the timeline is longer (typically 4–6 months)
Factors Affecting Recovery Time
- Type of procedure performed (e.g., meniscal repair vs. debridement)
- Coexisting conditions (e.g., cartilage or ligament damage)
- Age and muscle strength
- Preoperative knee function
- Adherence to physical therapy
- Sports history and general health
Things to Watch Out For
- Avoid twisting, jumping, or sudden movements early on
- Limit prolonged weight-bearing on the operated knee
- Do not resume sports without your doctor’s approval
- Stick to your rehab program consistently
- Special rehab protocols may be required for ligament or cartilage procedures
FAQ
-
When can I walk after knee arthroscopy?
Most patients begin assisted walking within 1–2 days, depending on the type of procedure.
-
Is physical therapy necessary?
Yes. Rehabilitation is essential for regaining strength, flexibility, and knee stability.
-
When can I return to sports?
Generally, 6–8 weeks for light activity and around 3 months for full return. ACL surgery requires a longer timeline.
-
How long does swelling last?
Swelling decreases significantly by the end of week 2. Mild puffiness may persist until week 4.
-
Will there be long-term pain?
Severe pain typically subsides within 3–7 days. Persistent pain should be evaluated by your doctor.
