Knee pain is one of the most common complaints we see at Phrapy — affecting students, office workers, and older adults alike. Whether your pain is caused by osteoarthritis, a ligament strain, or post-surgical recovery, the right exercises can significantly reduce pain and restore function.

The good news: you don't need a gym or any equipment. These five exercises, prescribed regularly at our Wakad clinic, can be done at home in under 20 minutes.

Before you start: Mild discomfort (3–4/10 on a pain scale) during exercise is acceptable. Stop immediately if you feel sharp or worsening pain. When in doubt, consult a physiotherapist before beginning any exercise programme.

The 5 Best Exercises for Knee Pain

Exercise 1

Quad Sets (Static Quadriceps Contraction)

Why it helps: Strengthens the quadriceps without bending the knee — ideal for acute pain or post-surgery.

How: Lie flat, legs straight. Tighten the muscles on top of your thigh (push the back of your knee into the floor). Hold 5 seconds, release. 3 sets × 15 reps each leg.

Exercise 2

Straight Leg Raises

Why it helps: Builds quadriceps and hip flexor strength while keeping the knee in a safe, straight position.

How: Lie flat. Bend one knee, foot on the floor. Keep the other leg straight, tighten the thigh and raise to the height of the bent knee. Hold 3 seconds, lower slowly. 3 sets × 12 per leg.

Exercise 3

Heel Slides

Why it helps: Gently restores knee flexion range — critical after surgery, for stiff arthritic knees, or after prolonged rest.

How: Lie on your back. Slowly slide one heel toward your buttocks by bending the knee as far as comfortable. Hold 5 seconds, slide back. 3 sets × 15 each side.

Exercise 4

Calf Raises

Why it helps: Strengthens the calf and improves dynamic support around the knee joint. Also improves circulation to reduce swelling.

How: Stand near a wall for balance. Rise up on your toes slowly, hold 2 seconds, lower. Keep knees slightly soft. 3 sets × 20. Progress to single-leg as strength improves.

Exercise 5

Terminal Knee Extension (TKE)

Why it helps: Activates the VMO (inner quadriceps) — the muscle most responsible for knee stability.

How: Anchor a resistance band (or folded bedsheet) at knee height behind your knee while standing. Straighten the knee against the resistance, hold 2 seconds, return. 3 sets × 15 per leg.

How Often Should You Do These?

Once daily, 5–6 days a week. Consistency matters more than intensity. Most patients see a noticeable reduction in pain within 2–3 weeks of daily practice.

When to See a Physiotherapist

If you experience any of the above, book a consultation at Phrapy.

Pro tip: Apply an ice pack (wrapped in a cloth) to your knee for 15 minutes after exercising if there is any swelling. Never apply ice directly to the skin.
