Knee Scar Tissue Rehabilitation: Breaking Adhesions and Restoring Motion

Post-Surgical Knee Stiffness Management

Arthrofibrosis (excessive scar tissue) limits flexion/extension. Early, consistent intervention is key.

Phase 1: Early Motion (Weeks 1–6)

• CPM (Continuous Passive Motion): 0–90°+ as tolerated, 6–8h/day.
• PT-guided PROM/AAROM: Heel slides, prone hangs, supine wall slides.
• Patellar mobilization: Superior/inferior/medial/lateral glides (critical for extensor mechanism).
• Edema control: Elevation, compression, cryotherapy, retrograde massage.

Phase 2: Progressive Stretching (Weeks 6–12+)

• Low-load prolonged stretch: 30–60 min in end-range flexion/extension (dynamic splint, towel stretch, prone hang with weight).
• Joint mobilizations (Maitland/Kaltenborn): Grade III/IV tibiofemoral, patellofemoral.
• Soft tissue techniques: IASTM, cross-friction, myofascial release to quad, patellar tendon, ITB, gastroc.
• Active exercises: Heel slides with strap, stationary bike (seat high → low), wall slides, step-ups.

Phase 3: Strengthening & Functional Integration

• Quadriceps: NMES + volitional activation → SAQ, LAQ, mini-squats, leg press.
• Hamstring/glute: bridges, RDLs, hamstring curls.
• Proprioception: single-leg stance, BOSU, perturbation training.
• Cardio: elliptical, swimming, rowing.

Modalities Adjuncts

• Heat before stretch: Moist heat 10–15 min → ↑ collagen extensibility.
• Ice after: 15–20 min → ↓ inflammation/pain.
• Ultrasound/laser: Limited evidence; may aid tissue heating.
• Topical NSAIDs / silicone gel: For superficial scar management.

Red Flags – Contact Surgeon

• No flexion gain in 2 weeks despite compliance.
• Increasing pain, swelling, erythema, warmth.
• Mechanical block (hard end-feel) suggesting cyclops lesion or hardware impingement.

Surgical Options (If Conservative Fails at 3–6 Months)

• Arthroscopic lysis of adhesions (LOA) + manipulation under anesthesia (MUA).
• Open arthrolysis for severe cases.

Consistency > intensity. Daily home program + weekly PT = best outcome.
