ACL Surgery Knee Extension Block Week 2 Heel Prop

Understanding ACL Surgery Knee Extension Block

After ACL surgery, patients often face a knee extension block. The knee does not straighten fully. It is common in post-op knee rehab. Cricketers in Jaipur notice this lag when bowling or fielding.

The block occurs due to swelling, pain, and muscle weakness. Tight tissues limit movement. Full knee straightening is key for cricket. Without it, running or pivoting risks injury. Swelling presses on the joint.

A knee extension lag appears as a gap between the back of your knee and a flat surface when lying down. Quadriceps weaken from lack of use and pain. Swelling displaces the kneecap.

Early work on extension reduces lag. Proper steps prevent issues. A physiotherapist measures lag angle during assessment and tracks progress.

What is Heel Prop Progression in Week 2

Heel prop is a simple exercise for ACL recovery week 2. Lie on your back and prop your heel on a rolled towel. Gravity pulls the knee straight. It targets the extension block gently.

In week 2, progression adds time or slight leg lifts. It fights straightening issues without strain. It suits Jaipur patients who bowl or field. Gravity works on the joint capsule.

Physiotherapists use heel prop to isolate gravity on the knee capsule and muscles. It avoids active pushing that irritates surgical sites. Combine with prone knee hangs. Measure the gap under your knee daily.

Step-by-Step Heel Prop Exercises for ACL Recovery

Do heel prop on a firm surface like a bed or mat. Use a towel roll, 10-15 cm high, under your heel. Keep the room quiet. Wear loose shorts for easy view. Looking for a Physiotherapist Near Me? Our team in Vaishali Nagar, Jaipur can assess you in person.

1. Lie on your back with legs straight. Place operated heel on the roll. Other leg flat. Let knees point to ceiling. Arms at sides.
2. Relax fully. Let knee drop using gravity. Hold 5-10 minutes. Repeat 3-4 times daily. Feel stretch in back of knee. Breathe steadily.
3. Progress: Tighten thigh muscle 5 seconds. Relax. Repeat 10 times. This wakes quads without load.
4. Next: Slide non-operated heel away to tighten other muscles. Hold 20-30 seconds. Repeat 5 times. Stop if pinching in knee.
5. Advanced: Place light weight like a water bottle on thigh above knee. Hold 3-5 minutes. Builds tolerance slowly.

Avoid forcing knee down or using too high a prop. This causes pain. Breathe through nose. Stop sharp pain and ice 15 minutes. If knee shakes, shorten holds.

Combine with quad sets: tighten thigh, hold 5 seconds, repeat 20 times. Track knee drop daily. Consistent use overcomes lag. Add ankle pumps—point and flex foot 20 times—to boost calf flow and reduce swelling.

Overcoming Knee Extension Lag in ACL Rehab

Knee extension lag needs a full approach. Start with rest, ice, and elevation to cut swelling. Elevate foot above heart 3 times daily, 20 minutes each. Use pillows under calf, not knee.

Physiotherapists measure lag with a goniometer. They guide from passive stretches to active exercises. Prone knee hangs: lie on stomach, hang operated leg off bed edge, hold 10 minutes, 3 times daily.

For Jaipur cricketers, address quad weakness. Straight leg raises: tighten quad first, lift 15 cm off bed, hold 5 seconds, lower slowly, 3 sets of 10 when pain-free. Do on firm surface.

Avoid limping. Use crutches until walking straight. Physio corrects gait. They watch you walk barefoot. Teach heel-toe pattern. Practice 10 minutes twice daily. Normal gait protects the knee from extra stress.

Watch for quad activation. Press back of knee down while tightening thigh. Use mirror or phone video. Poor activation worsens lag. Physio adds biofeedback—tapes or tools show muscle work. More on Knee Pain Treatment and how we assess it.

When to see a doctor, not a physiotherapist

Physiotherapy is not the right first step for everything. Seek medical assessment promptly if any of the following apply to you:

• Pain following a significant fall, road accident or other major injury
• Fever, chills or feeling generally unwell alongside the pain
• Weakness that is getting worse, or numbness that is spreading

If you lose control of your bladder or bowels, develop numbness around the groin, or have chest pain or breathlessness, treat it as an emergency and go to hospital.

Safety limits and when this does not apply

• Any exercise that sharply increases your pain, or leaves it raised the following morning, is too much for now.
• Electrotherapy and laser therapy have their own restrictions, including pacemakers, pregnancy and treatment over a known tumour. Your physiotherapist screens for these before use.
• This article is general information. It is not an assessment of your problem, and it cannot account for your medical history, medication or imaging.
