Quadriceps Tendinopathy (Knee) — Complete Exercise Program

Quad Sets

Re-activates the thigh muscle and supports knee control.

What it helps: Wakes up the quadriceps — the big thigh muscles that support and control your knee. Getting them firing is the foundation of a strong, steady leg.

1. Sit or lie with your leg straight.
2. Tighten the muscle on top of your thigh, pressing the back of your knee down.
3. Hold briefly, then relax.

Commonly done as 2-3 sets of 10, a few times a day.

Wall Sit

A steady hold that builds and calms the front-thigh (quad) muscles.

What it helps: Builds quad endurance in a steady hold, training the knee to support you through standing and stairs.

1. Stand with your back against a wall, feet shoulder-width apart and a step out from the wall.
2. Slide down until your knees are bent toward a comfortable, pain-free angle (don't go past 90°).
3. Hold the position, keeping your back against the wall and weight in your heels.
4. Slide back up to rest, then repeat.

Tips:

• Work in a range that doesn't sharpen the front-of-knee pain.
• Keep it steady — no bouncing; breathe normally through the hold.

Commonly done as hold 30–45s sets of 4–5 holds, most days.

Standing Quadriceps Stretch

Loosens the front-thigh muscles that pull on the kneecap.

What it helps: Loosens the front-thigh muscles so the knee bends comfortably and moves through its full range.

1. Stand tall, holding a wall or chair for balance.
2. Bend one knee and bring your heel toward your buttock.
3. Grasp your ankle and gently pull until you feel a stretch in the front of your thigh.
4. Hold, then switch sides.

Tips:

• Keep your knees close together and stand tall — don't arch your back.
• A gentle stretch, never forced.

Commonly done as hold 20–30s sets of 3 each side, daily.

Hamstring Stretching

Eases tightness behind the thigh that can pull on the low back.

What it helps: Keeps the back of the thigh flexible so the knee and hip move freely and your stride stays easy.

1. Lie on your back and loop a towel around one foot.
2. Gently straighten the knee toward the ceiling until you feel a light stretch.
3. Hold, then relax.

Tips:

• Stretch to mild tension, not pain.
• Breathe and ease into it.

Commonly done as hold 20–30s sets of 2–3 reps, 1–2 times a day.

Straight Leg Raises

Strengthens the thigh while protecting the joint.

What it helps: Builds quad and hip strength while the knee stays straight, so the muscle works hard without stressing the joint.

1. Lie down with one leg bent and the other straight.
2. Tighten your thigh and lift the straight leg a few inches.
3. Lower slowly.

Tips:

• Keep the knee straight as you lift.

Commonly done as 2-3 sets of 10, once or twice a day.

Stationary Bike

Builds motion and endurance with low impact.

What it helps: Keeps the joints moving and nourished while you build endurance — all with no pounding. One of the gentlest ways to stay active when a joint is sore.

1. Set the seat so pedaling is comfortable.
2. Pedal at an easy pace.
3. Increase your time gradually.

Commonly done as directed.

Walking Program

Short, frequent walks build endurance and confidence.

What it helps: Comfortable, frequent walking keeps the joints loose, builds your stamina, and rebuilds confidence on your feet. Little and often beats long and tiring.

1. Take short walks at a comfortable pace.
2. Increase your distance gradually as you feel able.

Tips:

• Use your assistive device as directed.

Commonly done throughout the day.

Wall Sit

A steady hold that builds and calms the front-thigh (quad) muscles.

What it helps: Builds quad endurance in a steady hold, training the knee to support you through standing and stairs.

1. Stand with your back against a wall, feet shoulder-width apart and a step out from the wall.
2. Slide down until your knees are bent toward a comfortable, pain-free angle (don't go past 90°).
3. Hold the position, keeping your back against the wall and weight in your heels.
4. Slide back up to rest, then repeat.

Tips:

• Work in a range that doesn't sharpen the front-of-knee pain.
• Keep it steady — no bouncing; breathe normally through the hold.

Commonly done as hold 30–45s sets of 4–5 holds, most days.

Mini Squats

Builds leg strength through a comfortable range.

What it helps: Builds hip and leg strength through a comfortable range, so everyday moves — sitting, standing, bending — take less out of your joints.

1. Stand holding a counter.
2. Bend your knees a small amount, keeping them behind your toes.
3. Return to standing.

Tips:

• Keep the movement small — this is not a deep squat.
• If bending under your own weight is not available yet, standing up from a higher chair asks the same muscles with less load.

Commonly done as 2-3 sets of 10, once or twice a day.

Terminal Knee Extensions

Strengthens the muscles that straighten the knee, standing against a band.

What it helps: Trains the quad to lock the knee out fully straight — the strength you rely on every time you stand and step.

1. Anchor a resistance band to something solid at about ankle height — a table leg or a door anchor.
2. Loop the free end around the back of your knee, then face the anchor and step back until the band is taut.
3. Stand with that knee slightly bent, weight through the foot.
4. Tighten your thigh and push the knee straight against the band's pull.
5. Let the knee bend slowly back to the start.

Tips:

• The band pulls the knee forwards; your job is to resist it. Nothing goes around your foot.
• Hold a counter if standing on that leg feels unsteady.

Commonly done as 2-3 sets of 10-15, once or twice a day.

Step-Ups

Builds strength for stairs and daily activity.

What it helps: Builds the leg and hip strength — and the control — for stairs, curbs, and everyday activity.

1. Step up onto a low step with your operative leg.
2. Step back down with control.

Tips:

• Hold a rail for balance.
• Going up stairs one foot at a time, holding the rail, is this exercise at this stage. If that is how you manage stairs at home, you are already doing it.

Commonly done as 2-3 sets of 10, once or twice a day.

Standing Hip Abduction

Strengthens the muscles on the side of the hip.

What it helps: Strengthens the outer-hip muscles that hold you steady whenever you're on one leg — which is every step you take. Stronger here, steadier hip.

1. Stand holding a counter for support.
2. Lift your leg out to the side, keeping it straight.
3. Lower slowly.

Tips:

• Keep your toes pointing forward.

Commonly done as 2-3 sets of 10-15, 1-2x daily.

Standing Quadriceps Stretch

Loosens the front-thigh muscles that pull on the kneecap.

What it helps: Loosens the front-thigh muscles so the knee bends comfortably and moves through its full range.

1. Stand tall, holding a wall or chair for balance.
2. Bend one knee and bring your heel toward your buttock.
3. Grasp your ankle and gently pull until you feel a stretch in the front of your thigh.
4. Hold, then switch sides.

Tips:

• Keep your knees close together and stand tall — don't arch your back.
• A gentle stretch, never forced.

Commonly done as hold 20–30s sets of 3 each side, daily.

1. Set the seat so pedaling is comfortable.
2. Pedal at an easy pace.
3. Increase your time gradually.

Commonly done as directed.

Step-Ups & Step-Downs

Advances stair strength and control.

What it helps: Advances your stair strength and the control to come down as confidently as you go up.

1. Step up onto a step, then step down slowly.
2. Control the lowering phase.

Tips:

• Hold a rail for balance.

Commonly done as 2-3 sets of 10, once or twice a day.

Leg Press

Builds leg strength with adjustable resistance.

What it helps: Builds solid leg and hip strength with resistance you can dial precisely to your comfort.

1. Start with light resistance.
2. Press through your whole foot.
3. Return slowly.

Commonly done as 2-3 sets of 10-15, a few times a week.

Mini Squats

Builds leg strength through a comfortable range.

What it helps: Builds hip and leg strength through a comfortable range, so everyday moves — sitting, standing, bending — take less out of your joints.

1. Stand holding a counter.
2. Bend your knees a small amount, keeping them behind your toes.
3. Return to standing.

Tips:

• Keep the movement small — this is not a deep squat.
• If bending under your own weight is not available yet, standing up from a higher chair asks the same muscles with less load.

Commonly done as 2-3 sets of 10, once or twice a day.

Single-Leg Balance

Improves balance and stability.

What it helps: Trains your hip and leg to stay steady when all your weight is on one side — which is most of walking. Better balance means a surer, more confident step.

1. Stand near a counter for safety.
2. Lift one foot and balance on the other leg.
3. Hold as able.

Tips:

• Holding the counter with one or both hands still counts. Letting go comes later, if it comes at all.

Commonly done daily.

Resistance Band Strengthening

Adds gentle resistance to build strength.

What it helps: Adds gentle, adjustable resistance to build strength steadily as you recover.

1. Use a band for hip or leg exercises as directed.
2. Move slowly through the range.

Commonly done a few times a week.

Cycling

Low-impact endurance and motion.

What it helps: Low-impact endurance that keeps the joints moving smoothly while you build fitness — easy on the body, good for the long run.

1. Set the saddle so your knee stays slightly bent at the bottom of the pedal stroke.
2. Begin with light resistance on flat ground, pedalling smooth, full circles.
3. Build the time you ride before you build the resistance or the hills.

Tips:

• Many people start on a stationary bike and move outdoors, as drawn here, once balance and confidence are back. The pedalling is the same either way.
• A saddle set too low is the usual reason a hip or knee feels cramped while riding.
• Your surgeon can say when getting onto a road bike is reasonable for you.

Commonly done as able.

Progressive Strengthening

Gradually increases strength as you recover.

What it helps: Gradually raises the challenge as you get stronger, so your body keeps adapting and improving rather than plateauing.

1. Begin with no added weight and get the movement smooth and comfortable first.
2. When a set starts to feel easy, add a light load - the ankle cuff shown here, a dumbbell or a band.
3. Sit tall, straighten the knee against the weight, hold briefly, then lower slowly.
4. Step the load up in small amounts rather than in jumps.

Tips:

• Progress one thing at a time - more weight or more repetitions, not both in the same week.
• If your form slips before the set ends, the load is too heavy.
• The ankle-weight knee extension is the example drawn. The same rule of small steps applies to whichever exercises your program includes.

Commonly done as directed.

Box Squats

Strengthens the legs with a controlled depth.

What it helps: Builds leg strength to a controlled, comfortable depth — strength you can trust without overloading the joint.

1. Stand in front of a sturdy chair or box.
2. Lower until you lightly touch, then stand.

Tips:

• Keep good form throughout.

Commonly done as 2-3 sets of 10, a few times a week.

Step-Ups & Step-Downs

Advances stair strength and control.

What it helps: Advances your stair strength and the control to come down as confidently as you go up.

1. Step up onto a step, then step down slowly.
2. Control the lowering phase.

Low-Impact Recreational Activities

Enjoyable activities that protect your joint.

What it helps: Getting back to the activities you enjoy in ways that are kind to your joints — the whole point of building this strength.

1. Choose activities that keep you moving without jarring the joint - walking, cycling and golf are three common ones.
2. Start with a short session and add time before you add intensity.
3. Spread them across the week rather than doing everything in one day.
4. Keep the effort at a level where you could still hold a conversation.

Tips:

• The picture shows three examples, not a list to work through - the best activity is the one you will keep doing.
• A little stiffness the next day is usual; a flare that lingers means the session was too long, not that the activity was wrong.
• Your surgeon or therapist can say when each activity is a reasonable one to add.

Commonly done as you like.
