Home Exercises in Osteoarthritis of the Knee

Osteoarthritis (OA) of the knee is a common degenerative joint condition characterized by cartilage wear, pain, stiffness, and reduced functional mobility. While pharmacological and surgical options exist, exercise therapy remains the cornerstone of conservative management. A well-structured home exercise program can significantly reduce pain, improve joint mobility, strengthen muscles, and enhance quality of life.

Objectives of Home Exercise Program

  • Reduce pain and stiffness
  • Improve joint range of motion (ROM)
  • Strengthen periarticular muscles (especially quadriceps)
  • Enhance joint stability
  • Improve functional activities like walking, stair climbing, and sitting-to-standing

General Guidelines

  • Exercise in a pain-free or minimal pain range
  • Perform exercises on a firm surface
  • Maintain regular breathing (avoid breath-holding)
  • Start with low repetitions and gradually progress
  • Apply hot fomentation before exercise if stiffness is present
  • Stop if there is sharp pain or swelling increase

1. Range of Motion (ROM) Exercises

Heel Slides

  • Lie on your back
  • Slowly bend your knee by sliding your heel toward your buttocks
  • Hold for 5 seconds, then straighten
  • Repetitions: 10–15 × 2 sets

Passive Knee Extension

  • Sit or lie with a rolled towel under your heel
  • Let gravity straighten your knee fully
  • Hold for 10–15 seconds
  • Repetitions: 10 times

2. Strengthening Exercises

Quadriceps Setting (Static Quads)

  • Sit with legs straight
  • Tighten thigh muscles by pressing the knee downward
  • Hold for 5–10 seconds
  • Repetitions: 10–15 × 2–3 sets

Straight Leg Raise (SLR)

  • Lie on your back, one knee bent and one straight
  • Lift the straight leg up to about 30–45°
  • Hold for 5 seconds, then lower slowly
  • Repetitions: 10–12 × 2 sets

Terminal Knee Extension (TKE)

  • Tie a resistance band behind the knee (or use towel support)
  • Slightly bend knee and then straighten against resistance
  • Repetitions: 10–15 × 2 sets

3. Stretching Exercises

Hamstring Stretch

  • Sit with one leg straight
  • Lean forward from hips (not spine)
  • Hold stretch for 15–20 seconds
  • Repetitions: 3–5 times

Calf Stretch

  • Stand facing a wall
  • Keep back leg straight and heel on ground
  • Lean forwardHold 20 seconds
  • Repetitions: 3–5 times

4. Functional Exercises

Sit-to-Stand

  • Sit on a chair
  • Stand up without using hands if possible
  • Slowly sit back down
  • Repetitions: 8–12 × 2 sets

Step-Ups

  • Use a low step
  • Step up with affected leg, then down
  • Repetitions: 10 × 2 sets

5. Low-Impact Aerobic Exercises

  • Walking (on even surface)
  • Cycling (stationary bike)
  • Swimming (if available)

Duration: 20–30 minutes, 3–5 times/week

Precautions

  • Avoid deep squatting and prolonged kneeling
  • Avoid high-impact activities like running or jumping
  • Use proper footwear
  • Maintain optimal body weight

Conclusion

Home exercises are a safe, cost-effective, and essential component in managing knee osteoarthritis. Consistency is key—patients who adhere to a daily routine often experience significant improvement in pain, mobility, and overall function. A physiotherapist-guided program tailored to individual needs yields the best outcomes.
