Knee arthroscopy is one of the most common orthopedic procedures worldwide: more than 4 million procedures annually. Treatment success depends 50% on proper rehabilitation. We break down each recovery stage.
What is arthroscopy and when is it needed
Arthroscopy is a minimally invasive surgical procedure through 2–3 punctures of 5 mm each. Indications:
- Meniscus Tear — resection or suturing
- Cruciate Ligament Injury — ACL reconstruction
- Chondromalacia — chondroplasty, microfracturing
- Removal of loose bodies
- Synovectomy for chronic synovitis
Important: Not every meniscus injury requires arthroscopy. For degenerative changes, regenerative methods (CGF + Lipogems®) may be more effective and less traumatic.
Stage 1: First 24–48 hours
Main goal — swelling and pain control:
- RICE protocol: Rest (rest), Ice (ice 15–20 min every 2 hours), Compression (compression bandage), Elevation (leg above heart level)
- Pain relief: NSAIDs as prescribed (ibuprofen 400–600 mg ? 3/day with food)
- Anticoagulants: thrombosis prophylaxis (enoxaparin subcutaneously)
- Walking: with crutches, partial weight-bearing on the leg
Stage 2: Week 1–2
- Suture removal (day 7–10)
- Start of isometric exercises (quadriceps tension without movement)
- Knee flexion to 90° (gradually)
- Walking with one crutch > without crutches (for meniscus resection)
For ACL reconstruction: crutches 4–6 weeks, brace with flexion limitation.
Stage 3: Week 2–6
- Full range of motion (0–130°)
- Active physical therapy: stationary bike (no resistance), swimming (crawl)
- Balance and proprioception exercises
- Quadriceps and hamstring strengthening
Stage 4: Month 2–3
- Straight-line jogging (from week 8 for meniscus resection)
- Strength exercises with weights
- Functional tests (single-leg squat, jumps)
Stage 5: Month 3–6 (return to sports)
- Sport-specific training
- Readiness tests: hop test, Y-balance test
- Limb symmetry index ?90%
Recovery timelines: table
| Procedure | Walking without crutches | Driving | Office work | Sports |
|---|---|---|---|---|
| Meniscus resection | 1–2 wk. | 1–2 wk. | 1 wk. | 6–8 wk. |
| Meniscus repair | 4–6 wk. | 4–6 wk. | 2–3 wk. | 4–6 mo. |
| ACL reconstruction | 4–6 wk. | 6–8 wk. | 2–4 wk. | 6–9 mo. |
| Chondroplasty | 6–8 wk. | 6–8 wk. | 2–4 wk. | 6–12 mo. |
Alternative: regenerative treatment without surgery
Not all knee injuries require arthroscopy. The MIBRAR® method allows treatment of:
- Degenerative meniscus tears — without resection (meniscus preservation)
- Partial ligament injuries — accelerated healing
- Stage I–III osteoarthritis — cartilage regeneration
Advantage: no incisions, no general anesthesia, rehabilitation 2–4 weeks instead of 2–6 months.
