Understanding Knee Extension Issues After ACL Surgery

Knee extension lag means the knee does not straighten fully after ACL reconstruction. The lag shows as a gap under the kneecap when standing. Causes include swelling, pain, and immobilisation. Swelling blocks movement by filling the joint space. Pain leads to avoidance, so muscles do not fire properly. Braces limit motion, causing stiffness. They often keep the knee at 90 degrees or less early on. Knee immobilisation after surgery protects the new ligament but lets joint capsule and muscles adapt to a bent position.

These tighten tissues. Tight hamstrings pull back. Weak quads fail to push straight. Knee flexion lag can also appear, where bending lags behind straightening. Seek assessment at Trivayu Physio Center, Vaishali Nagar, Jaipur. A physio checks range, strength, and graft stability. They measure how much force you need to straighten passively versus actively.

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.
