• Goniometer: Plastic arm model marks angles in degrees. Fixed arm along thigh. Moving arm follows shin.
• Smartphone app: Free apps use phone camera. Hold phone steady against leg bones.
• DIY option: Ruler and protractor taped together, but less accurate. Mark 90 degrees.

Safety first, no force. Get tools from Jaipur pharmacies. Test on good knee first. Clean tools. Have a mirror or helper. Clinic physios use full-size metal goniometer.

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.
