Now I have strong references from the TKR physiotherapy management textbook. Let me compile a comprehensive, structured protocol based on evidence from these sources and clinical knowledge.
Physiotherapy Protocol: Total Knee Replacement (TKR)
Starting Point: Week 2 | Patient Age: 70 years | Baseline: Walker ambulation, ROM 30°
Goal: Full Independence with Functional ROM and Community Ambulation
Patient Profile Summary
| Parameter | Detail |
|---|---|
| Age | 70 years |
| Surgery | Total Knee Replacement (TKR) |
| Starting Week | Week 2 post-op |
| Baseline Mobility | Ambulating with walker |
| Baseline ROM | Knee flexion 30° |
| Goal | Independent ambulation, functional ROM (≥110°), return to daily activities |
Note for 70-year-old patients: Expect slightly slower progression due to age-related sarcopenia, reduced proprioception, and potential comorbidities (hypertension, osteoporosis, diabetes). Prioritize fall prevention and cardiovascular tolerance at every phase. Pain and swelling must be monitored more conservatively. (Physical Therapist Management of Total Knee Arthroplasty, p. 26–27)
PHASE 1 — Early Mobility & ROM Recovery
Week 2 – Week 4
Goals:
- Increase knee flexion from 30° → 70°
- Full active knee extension (0°)
- Safe walker ambulation on level surfaces
- Reduce post-operative swelling and pain
- Prevent DVT and joint stiffness
Exercises
| Exercise | Reps/Sets | Notes |
|---|---|---|
| Ankle pumps | 20 reps × 3/day | DVT prevention; do in bed or chair |
| Quad sets (isometric) | 10 reps × 3, hold 5 sec | Tighten quads with knee straight on bed |
| Heel slides (supine) | 10–15 reps × 3/day | Slide heel toward buttocks; target 60–70° |
| Terminal knee extension (TKE) | 10 reps × 3 | Rolled towel under knee; extend to 0° |
| Short arc quads | 10 reps × 3 | Towel under knee at 30–40°; extend fully |
| Straight leg raise (SLR) | 10 reps × 3 | Only if quad control is adequate; avoid lag |
| Sitting knee flexion (gravity-assisted) | 10 reps × 3 | Sit at edge of bed/chair; let gravity flex knee |
| Standing hip abduction (with walker) | 10 reps × 2 each side | Improves hip stability for gait |
Ambulation & Gait Training
- Aid: Standard walker (4-wheeled or standard)
- Walk 2–3× daily; begin with 10–15 meters, increase by 10% every 2 days
- Practice step-to gait pattern
- Stair training (step-to pattern): "Good leg up, bad leg down" — introduce only if tolerated by Week 3
- Apply ice pack (15–20 min) after every session to reduce swelling
Modalities
| Modality | Purpose | Frequency |
|---|---|---|
| Cryotherapy (ice pack) | Pain & swelling control | After every session |
| TENS / IFC | Pain relief | 1× daily if pain >5/10 |
| Neuromuscular Electrical Stimulation (NMES) on vastus medialis | Quadriceps re-education | 3–5×/week (p. 26, Avramidis et al.) |
Milestones to Advance to Phase 2
- Knee flexion ≥ 70°
- Full active extension (0°)
- Walking 50+ meters with walker without fatigue
- Pain ≤ 4/10 at rest and with activity
PHASE 2 — Strengthening & Gait Progression
Week 4 – Week 7
Goals:
- Increase knee flexion from 70° → 100°
- Transition from walker → single forearm crutch or quad cane
- Improve quadriceps and hip strength
- Normalize gait pattern
Exercises
| Exercise | Reps/Sets | Notes |
|---|---|---|
| Heel slides (progressive) | 15 reps × 3 | Target 90–100° |
| Wall slides / mini squats | 10 reps × 3 | 0–40° knee flexion; no pain |
| Step-ups (low step, 10 cm) | 10 reps × 3 each leg | With support; advance to 15 cm |
| Standing knee flexion | 10 reps × 3 | Hold onto surface; flex to 90°+ |
| Hip extension (standing) | 10 reps × 3 | Improves gait push-off |
| Calf raises (bilateral → unilateral) | 10 reps × 3 | Start bilateral; advance when strong |
| Seated leg press (low resistance) | 10 reps × 3 | 0–60° arc; add resistance progressively (p. 26, Petterson et al.) |
| Balance board (bilateral stance) | 30 sec × 3 | Proprioception training |
| Stationary cycling | 10–15 min | Set seat high; very effective for ROM |
Ambulation & Gait Training
- Aid transition: Walker → forearm crutch (Week 5–6, based on quad strength and balance)
- Walk 100–300 meters continuously; increase gradually
- Begin reciprocal gait pattern (step-over-step) on level ground
- Stair climbing (reciprocal): Introduce when strength and balance allow (Week 6–7)
- Outdoor walking on even surfaces under supervision
Functional Training
- Practice sit-to-stand from standard chair height; reduce chair height as strength improves
- Toilet transfer training (essential for independence)
- Bathing/dressing with hip and knee precaution review
Milestones to Advance to Phase 3
- Knee flexion ≥ 100°
- Walking 200+ meters with crutch/cane
- Able to perform step-over-step stairs
- Sit-to-stand from standard chair independently
- Quad strength ≥ 4/5 MMT
PHASE 3 — Functional Independence
Week 7 – Week 12
Goals:
- Achieve knee flexion ≥ 110° (functional target for activities of daily living)
- Transition to single-point cane → no aid
- Full community ambulation
- Return to ADLs independently
- Falls prevention and balance mastery
Exercises
| Exercise | Reps/Sets | Notes |
|---|---|---|
| Stationary cycling | 20–30 min | Progress resistance; excellent ROM + cardio |
| Leg press (progressive resistance) | 3 × 12 | 0–90° arc; evidence-based for quad strength (p. 26, Bade et al. 2017) |
| Step-ups (15–20 cm step) | 3 × 12 each leg | Forward and lateral step-ups |
| Lunges (partial, supported) | 3 × 10 | Only if flexion >100° and well-tolerated |
| Single-leg stance | 30–60 sec × 3 | Eyes open → eyes closed; add unstable surface |
| Tandem walking | 10 meters × 3 | Heel-to-toe; balance and gait quality |
| Sit-to-stand (progressively lower chairs) | 3 × 10 | Target 43 cm (standard toilet height) |
| Nordic walking / outdoor walks | 20–30 min | With/without cane based on ability |
| Proprioception on foam pad | 30–60 sec × 3 | Reduces fall risk significantly in elderly |
Ambulation & Gait Training
- Aid transition: Single cane → no aid (target Week 10–12)
- Community ambulation: uneven surfaces, curbs, ramps, shopping environments
- Stair training (reciprocal, no railing dependence): Progress to confidence without railing
- Driving assessment if right knee (typically Week 8–10, surgeon clearance required)
ADL & Home Independence Goals
| Activity | Target Achievement |
|---|---|
| Walking in home without aid | Week 8–10 |
| Bathing/dressing independently | Week 7–8 |
| Cooking/light housework | Week 8–10 |
| Stair climbing (reciprocal, no railing) | Week 10–12 |
| Community ambulation independently | Week 10–12 |
| Low-impact activities (walking, swimming, cycling) | Week 12 |
Fall Prevention (Critical for Age 70)
- Home hazard assessment (remove rugs, install grab bars in bathroom)
- Educate on safe movement strategies
- Nighttime lighting for toilet trips
- Balance training must continue throughout this phase
- Consider referral to falls prevention program post-discharge (p. 27, Falvey et al. 2016)
ROM Progression Summary
| Week | Target Knee Flexion | Assistive Device | Key Milestone |
|---|---|---|---|
| Week 2 | 30° (baseline) | Walker | Starting point |
| Week 3 | 50–60° | Walker | Heel slides, sitting flexion |
| Week 4 | 70° | Walker | Phase 1 complete |
| Week 5–6 | 80–90° | Forearm crutch/cane | Stationary cycling begins |
| Week 7–8 | 95–100° | Single cane | Step-over-step stairs |
| Week 9–10 | 100–105° | Single cane / unaided | Community walking |
| Week 11–12 | 110°+ | Unaided | Functional independence |
Session Frequency Recommendations
| Phase | Frequency | Duration |
|---|---|---|
| Phase 1 (Weeks 2–4) | 5 sessions/week | 45–60 min |
| Phase 2 (Weeks 4–7) | 3–4 sessions/week | 45–60 min |

| Home exercise program | Daily throughout | 20–30 min |
Red Flags — Stop and Refer
- Sudden increase in knee swelling or warmth (rule out infection/DVT)
- Calf pain or Homan's sign positive → DVT screening urgently
- Wound dehiscence or discharge
- Severe pain (>7/10) not responsive to ice and rest
- Unexplained fever >38.5°C
- Chest pain or dyspnea during exercise → cardiac evaluation

| Knee Flexion ROM | 30° | ≥110° |
| Timed Up and Go (TUG) | Typically >20 sec | <12 sec (community ambulation) |
| VAS Pain Score | Variable | ≤2/10 at rest |
| 6-Minute Walk Test | Limited | ≥300 meters |
| Oxford Knee Score / KOOS | Baseline recorded | Significant improvement |
