So what should I do in exercises and physiotherapy?
Asking for Preferences
Please go ahead and describe your condition or situation - what's going on, any diagnosis you've received, symptoms, or what you're recovering from. The more detail you share, the more relevant my advice can be.
No, the MCL knee you're talking about, ma'am.

Here is a thorough, phase-by-phase guide to MCL knee physiotherapy and exercises, based on clinical protocols from Mass General Hospital Sports Medicine, Textbook of Family Medicine 9e, Rheumatology (Elsevier 2022), and a recent 2024 systematic review on non-operative MCL rehabilitation (PMC).
MCL Knee Injury: Exercises & Physiotherapy by Phase
First, know your grade - timing differs
| Grade | Laxity | Phase 1 Brace | Return to Sport |
|---|---|---|---|
| Grade 1 | 1-4 mm | ~3 weeks | ~1 week |
| Grade 2 | 5-9 mm | ~6 weeks | 2-4 weeks |
| Grade 3 | >10 mm | ~6 weeks (locked in extension x10-14 days) | 4-8 weeks |
Phase 1 - Early Injury (Days 1-3 weeks for Grade 1 / Days 1-6 weeks for Grade 2 & 3)
Goals: Control pain/swelling, restore ROM, re-activate the quadriceps, normalize walking.
Immediate care (RICE + bracing)
- Ice 20 min, 3x/day (towel between skin and ice)
- Elevate the leg, use elastic compression if swollen
- Hinged knee brace - Grade 1 & 2: full ROM brace. Grade 2 & 3: locked in extension for 10-14 days, then limited to 0-90 degrees for 2 more weeks
- Weight bearing - partial weight bearing with crutches; progress as pain allows
Exercises (brace off, 5-7 days/week, 1-2x/day)
| Exercise | Sets/Reps | Notes |
|---|---|---|
| Quad set (tighten quad, press knee down flat) | 1-2 sets x 15-20 reps | Key for quad re-activation |
| Heel slide (lying, slide heel toward buttocks) | 1 set x 5-15 min or 15 reps | Restores knee flexion ROM |
| Heel prop (heel on rolled towel, knee hanging in extension) | 5 min | Restores full extension |
| Straight leg raise | 3 sets x 10 reps | No bend at knee |
| Short-arc quad (pillow under knee, straighten leg 45-0°) | 3 sets x 10 reps | Quad strengthening |
| Standing hamstring curl | 3 sets x 10 reps | |
| Standing toe raises | 3 sets x 10 reps | |
| Hip abduction (lying side, raise leg) | 3 sets x 10 reps | |
| Partial squats / wall slides | 3 sets x 15 reps | Avoid >45° bend initially |
Balance goal: Stand on one leg for up to 60 seconds before moving to Phase 2.
Phase 2 - Intermediate (3 weeks post Grade 1 / 6 weeks post Grade 2 & 3)
Goals: Full ROM, strengthen quads/hamstrings/hips, functional mobility, early proprioception.
Progress these exercises (3 days/week)
| Exercise | Sets/Reps |
|---|---|
| Stationary bike (seat high, low resistance) | Start 5-7 min, build to 15-30 min |
| Wall squat with ball between knees | 3 sets x 15 reps |
| Lateral step-up | 3 sets x 10-15 reps |
| Hip adduction (seated, squeeze ball) | 3 sets x 15 reps |
| Squat to chair | 3 sets x 15 reps |
| Single-leg strengthening progression | 3 sets x 10 |
| Prone hang (lie face down, knee hangs over edge) | 5 min - restores full extension |
Stretching (5-7 days/week)
- Hamstring stretch - 3-5 reps, hold 15-30 sec
- Quad stretch - 3-5 reps, hold 15-30 sec
- Calf stretch - 3-5 reps, hold 15-30 sec
Proprioception (balance training)
- Single leg balance: progress from flat floor → foam pad → mini-trampoline
- 3-way RDL (single-leg deadlift reaching forward, sideways, across): 3 sets x 30 sec each leg
- Copenhagen plank (inner thigh/adductor strength - very important for MCL)
- BAPS board / balance board work
Phase 3 - Late Stage / Return to Sport
Goals: Running, plyometrics, sport-specific drills. Only begin with physio/doctor approval.
Strength
- Leg press (supine or machine, 0-45° range)
- Mini squats - bilateral → unilateral
- Hip thrust / glute bridge - single leg progression
- Side plank for hip/core stability
Dynamic training
- Lateral step-down (eccentric control)
- Hamstring slider (lying, pull heel toward you on slippery surface)
- Plyometrics - start low-impact: box step, then progress to jump landing
- Speed and agility drills (lateral shuffles, cones) once running normalized
What to AVOID (especially early)
- Leg extension machine (quad extensions) - stresses the joint
- Stairmaster / stair climber machines
- Lunges initially
- Squats past 90 degrees of knee flexion
- Pivoting or twisting on the injured leg
- High-impact / plyometric exercises before cleared
Key physiotherapy modalities
- Ice post-exercise throughout rehab
- Electrical stimulation (TENS/NMES) - for pain control and quad muscle re-education
- Ultrasound or whirlpool - for tissue healing and pain
- Manual therapy - joint mobilization to restore full ROM
- Taping / bracing - continues until full stability is confirmed
Important notes
- Grade 1 & 2 MCL injuries almost always heal fully with conservative (non-surgical) treatment, per both Rheumatology (Elsevier 2022) and Family Medicine 9e.
- Grade 3 isolated MCL injuries can also be managed non-operatively in most cases. Surgery is reserved for Grade 3 injuries combined with ACL/PCL tears that don't respond to physiotherapy.
- Avoid breast-stroke swimming (it stresses the MCL) - freestyle is fine once in the water phase.
- Progress should be guided by pain: never push through sharp medial knee pain during exercises.
If you're not already working with a physiotherapist, it's worth getting at least a few sessions so they can assess your specific grade and tailor these progressions to you.
