Knee Extension Exercises Week 2 After ACL Surgery

After ACL surgery, week 2 marks early recovery. Your knee needs gentle work to regain full extension. This prevents stiffness and builds strength. Home exercises like straight leg raises support this. Full extension reduces limp risk and aids walking.

These drills focus on progressive knee extension post surgery. Get clearance from your physiotherapist first. They check range of motion and swelling. In Jaipur, visit Trivayu Physio Center for assessment. Dr. Jyoti Choudhary and team guide post-surgery rehab. Start slow to aid ACL reconstruction recovery. A physiotherapist watches form to avoid graft strain.

Understanding Knee Extension in Week 2 After ACL Surgery

Knee extension means straightening your leg fully so the knee locks straight. In week 2 after ACL surgery, this matters for normal walking later. Poor extension leads to limp or weakness. It creates uneven leg lengths during steps. Work now sets base for later bending or squatting.

Straight leg raise strengthens quadriceps without bending the knee. This improves extension safely. Focus on small daily gains. Your physio measures extension lag between knees. Looking for a Physiotherapy Near Me? Our team in Vaishali Nagar, Jaipur can assess you in person.

Safe Guidelines Before Starting Extension Drills

In week 2, your knee graft starts healing but remains fragile. Swelling drops but pain lingers. Start drills if pain-free at rest and walking short distances with crutches. Use ice after sessions, 15 minutes on, wrapped in cloth. Elevate leg above heart level between sets.

Do exercises on a firm bed or mat. Lie on your back. Breathe steadily: inhale to prepare, exhale during effort. Stop if sharp pain, clicking, warmth or more swelling occurs. More on Knee Pain Treatment and how we assess it.

• Check with physio if fever, redness or calf pain – signs of clot risk.
• Avoid twisting knee or full weight without brace.
• Limit sessions to 2-3 times a day, 10-15 minutes each.
• Wear knee brace during day unless physio says remove.

Signs to stop: Increased limp, knee buckling or night pain. Contact Trivayu Physio Center in Vaishali Nagar or Vidyadhar Nagar for check-up. They adjust based on surgery type.

Key Straight Leg Raise Exercise for Knee Straightening

Straight leg raise (SLR) targets quadriceps without joint stress. A physiotherapist teaches this to activate the muscle.

1. Lie on back on firm surface. Bend good leg at knee, foot flat, toes up.
2. Tighten thigh muscle of surgery leg by digging heel down. Press back of knee flat into bed.
3. Lift surgery leg 6 inches off bed, toes up, knee locked straight. Keep pelvis level.
4. Hold 5 seconds. Lower slowly over 3 seconds.

In week 2, aim for 8-10 raises per set, 2-3 sets daily. Rest 1 minute between sets. Progress by holding 10 seconds or adding 0.5 kg ankle weight if physio approves.

Common errors: Bending knee, arching back or swinging leg. Keep pelvis steady. Practice in mirror.

Progressive Extension Drills to Build on SLR

Build on SLR with these home exercises. A physio progresses you based on SLR control. If mobility limited, they use Manual Therapy in clinic.

Heel Slides for Gentle Flexion and Extension

Sit or lie with legs straight. Slide heel towards buttocks pain-free, to 30-90 degrees bend. Hold 3 seconds, slide back. 10 times per set, 2 sets. You may also find Knee Straightening Drills After ACL Surgery Week 2 useful.

Prone Hangs for Passive Knee Extension

Lie on stomach on bed edge. Let surgery leg hang off. Relax for gravity to straighten knee. Hold 2-3 minutes, 2-3 times daily. Add pillow under hips if intense.

Seated Knee Extensions for Controlled Strength

Sit on chair edge with thigh supported. Straighten surgery knee to full lock. Hold 3-5 seconds, lower over 5 seconds. 8-10 reps, 2 sets. Add light therapy band if ready.

Quad Sets as Foundation Drill

Lie or sit with leg straight. Tighten quad by pushing knee down. Hold 5-10 seconds. 10-15 reps. Do before SLR sets.

Track extension by heel height off bed or photo. Note pain 0-10. If progress slow, Electrotherapy like TENS may help in clinic.

Tips for Effective Home Rehab and When to Seek Help

Make routine: Morning, afternoon, evening. Ice 15 minutes after, elevate. Track knee angle with mirror or phone photo. Aim 5-10 degrees gain per week.

Mild ache okay, stop for sharp pain. Walk 5-10 minutes with crutches or brace.

• Warm up with ankle pumps: 20 times.
• Combine with quad sets.
• Rest if swelling rises.
• Hydrate and eat protein.

Seek help if no gain in 3-5 days or pain worsens. Dr. Hritika Choudhary handles post-op rehab with Orthopaedic Rehabilitation. Visit for personalised plan.

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.
