Quadriceps Isometric Sets
Isometric quadriceps activation without joint movement. Preserves strength without overloading the joint — a cornerstone of conservative treatment for knee osteoarthritis.
How to perform
- Starting position. Sit on the floor with the affected leg extended in front of you.
- Step 2. Place a rolled-up towel under your knee.
- Step 3. Press your knee down into the towel by strongly contracting your thigh.
- Return. Hold the contraction for 5–10 seconds and relax.
When not to perform
- Acute pain with the contraction
- Recent post-operative without medical clearance

Straight-Leg Raise
Strengthens the quadriceps and hip flexors without bending the knee. Effective for moderate knee osteoarthritis when squats are contraindicated.
Mini Squat (0 to 45 Degrees)
Partial squat limited to the first 45 degrees of knee flexion, protecting the patellofemoral joint while recruiting quadriceps, glutes, and knee stabilizers. The exercise of choice in knee osteoarthritis and the early phase of meniscal or ligament rehab.
Standing Quadriceps Stretch
Stretches the quadriceps and rectus femoris, frequently shortened in patients with chondromalacia. Reduces traction on the patella.
