Knee Arthroscopy Recovery: Timeline and Stages

Recovery after knee arthroscopy: what to do in the first days, when you can walk without crutches, drive and return to sport, and which symptoms mean you should call your surgeon straight away.

What arthroscopy is and when it is needed

Arthroscopy is surgery through 2–3 small portals: the surgeon inserts a camera and instruments into the joint. It is used for an acute traumatic meniscus tear, especially if the knee locks, for meniscus repair, anterior cruciate ligament (ACL) reconstruction, removal of loose bodies and some cartilage injuries.

For degenerative (age-related) meniscus tears without locking, trials including FIDELITY and ESCAPE found that exercise therapy is on average as good as arthroscopy. People over 40–45 are therefore usually offered conservative treatment first. More on the meniscus tear page.

The first days after surgery

Ice for 15–20 minutes several times a day, leg elevated, compression bandage.
Painkillers only as prescribed by your doctor, at the prescribed dose.
Thrombosis prevention as decided by the surgeon — it depends on the operation and your risk factors.
Walking on crutches with the weight-bearing your surgeon allows: after partial meniscectomy it is usually increased quickly, after meniscus repair and ACL reconstruction it is restricted.
From day one: tightening the thigh muscles without moving the knee, and ankle pumps.

Weeks 1–6

Stitches are usually removed after 10–14 days. The main goal of the first weeks is to straighten the knee fully and gradually regain bending. Once you reach about 110° of flexion, a stationary bike without resistance is added, followed by balance work and thigh strengthening. A physiotherapist plans the programme according to what was done in the joint.

Months 2–6: returning to activity

Return to running and sport is guided by tests, not the calendar: the operated leg should have at least 90% of the strength of the healthy one, and hop tests should cause no pain or swelling. After ACL reconstruction, returning to sport too early increases the risk of re-rupture.

Approximate timelines

Operation	Off crutches	Office work	Sport
Partial meniscectomy	a few days – 2 weeks	1–2 weeks	6–12 weeks
Meniscus repair	4–6 weeks	2–4 weeks	4–6 months
ACL reconstruction	2–6 weeks	2–4 weeks	9–12 months

Timelines vary with the operation, age and rehabilitation. You can drive once you manage without crutches and can perform an emergency stop confidently and without pain; after surgery on the right leg this is usually later.

When to contact your doctor urgently

Temperature above 38 °C, redness or discharge from the wounds.
Increasing calf pain and swelling — possible thrombosis.
Sudden shortness of breath or chest pain — call an ambulance.
The knee locks again or swells up suddenly.

How we help

If you have been offered arthroscopy and want a second opinion or to compare clinics in Germany, send us your MRI and report. We forward your request to several partner clinics: each clinic reviews the images itself and quotes its own conditions and price. The decision to operate is made by the clinic physician. Send a request.

Who it is not suitable for and possible risks

Contraindications

Active infection — at the injection site or systemic, with fever.
Active cancer or ongoing chemotherapy.
Blood clotting disorders or a low platelet count. Anticoagulants are discussed with the physician.
Pregnancy and breastfeeding — the procedure is usually postponed.
A corticosteroid injection into the same area in recent weeks.
Severe stage IV osteoarthritis with axial deformity and joint destruction — joint replacement is usually discussed instead.

Possible risks

Pain and swelling at the injection site for 1–3 days.
Bruising where blood or fat tissue is taken.
Rarely, infection. The procedure is therefore performed under sterile conditions with ultrasound or X-ray guidance.
The effect may be absent or smaller than expected.

If any of these apply to you, mention it in your request. The coordinator will check with the clinic physician whether treatment is possible. Contact a coordinator.

Scientific evidence

Studies of regenerative methods show mixed results. Clinic physicians rely on research including the following:

Thorlund JB et al. Arthroscopic surgery for degenerative knee: systematic review and meta-analysis of benefits and harms. Br J Sports Med, 2015.
Sihvonen R et al. Arthroscopic partial meniscectomy versus sham surgery for a degenerative meniscal tear. N Engl J Med, 2013.

Frequently asked questions

How long does recovery take after knee arthroscopy?

Full recovery takes 4–12 weeks depending on the extent of the procedure. Walking is possible within 1–3 days, driving — within 1–2 weeks, sports — within 2–4 months.

What exercises are needed after arthroscopy?

First days — isometric exercises (muscle contraction without movement). After 1–2 weeks — flexion/extension. After 4–6 weeks — stationary bike, swimming. The rehabilitation specialist creates an individual program.

Can arthroscopy be avoided with a meniscus injury?

In some cases — yes. The regenerative method allows restoration of the damaged meniscus without surgery for partial tears and degenerative injuries.

How does RegenPAS help organise treatment?

RegenPAS is a patient service centre in Munich, not a clinic. We review your images and symptoms and send a request to several partner clinics at once. Clinics that can accept you send their own conditions and price; prices differ between clinics, and you choose the option that suits you. The coordinator replies within 24 hours, and a clinic physician’s preliminary opinion follows in 1–3 business days. We then arrange the appointment, visa invitation, interpreter, transfers and accommodation. Treatment decisions are made by the clinic physician. Contact a coordinator.

What is needed for a preliminary assessment?

Your MRI (or CT, X-ray) report and the images if you have them, plus a short description of your symptoms and previous treatment. Send them via the form on the website — the assessment is free and without obligation: the coordinator replies within 24 hours, and the clinic physician’s preliminary opinion follows in 1–3 business days.

How much does treatment cost and how long do I need to stay in Munich?

The cost depends on the method, the diagnostics needed and the clinic itself: prices differ between clinics. We request offers from several clinics and send you their conditions and quotes so you can compare. Price guidance is on the treatment cost page. For an outpatient procedure, 2–3 days in Munich are usually enough: examination, procedure and follow-up visit.

Clinic and method matching — free of charge

Describe your case and attach your MRI report. We will identify clinics that use the relevant methods and forward your request to them. No obligation; we reply within 24 hours.
