After knee surgery, rehab decides how mobile, strong and resilient your knee becomes again, whether after a knee replacement or an arthroscopic procedure. At BodyLab in Zurich Altstetten, we support you step by step after your knee surgery, from the first days on crutches back to cycling, hiking or sport.
Post-Op Rehab
Discover which procedures this rehab is designed to conquer
The most common scenario is rehab after a total knee replacement (TKR)—a prosthetic knee joint. We are also right there with you after knee arthroscopy on the meniscus or cartilage, after a knee fracture, and after an acl tear (ACL). Every single one of these procedures has its own specific recovery protocol, but the progression always follows the exact same logic: active as early as possible, protected as much as necessary.
We will also guide you through your recovery after less common procedures, such as osteotomy.
You can find everything you need to know about ACL rehab following an acl tear on our dedicated page, and if you are experiencing knee pain without having had surgery, our overview on knee pain is here to help.
Your rehab after knee surgery: Three steps to come back stronger
By the way: if your surgery is scheduled but not yet performed, starting now pays off. The strength and muscle activation you build before the procedure won't have to be rebuilt from scratch afterward. Ask your surgeon or family doctor for a prescription for this preparation—known as prehabilitation—or reach out to us directly, and we will maximize the time leading up to your surgery together.
Phase 1: Protect & Mobilize
Control swelling, respect the natural healing process, and reclaim the most valuable asset of these weeks with manual and active therapy: extension and flexion, combined with the first activation exercises for your thighs. This phase also includes gait training with crutches to prevent any compensatory limping from taking hold. If there is significant swelling, manual lymphatic drainage provides excellent support.
Phase 2: Strength and Function
Targeted strengthening of your quadriceps and glutes, enhancing balance and mastering everyday movements like climbing stairs and standing up. Medical Training Therapy (MTT) is perfect for this—equipment-based strength training under professional guidance. Best of all, you train right where you receive treatment: directly in the clinic.
Phase 3: Reclaiming Your Everyday Life and Athletic Peak
Longer walks, cycling, hiking, swimming—and depending on your starting point and procedure, a return to your favorite sport. We make your progress measurable: flexion angle, swelling reduction, and strength comparison with your other side. These values, combined with our clinical expertise, define your next steps.
How quickly you power through these phases depends on your specific surgery and your body's natural healing response: after a simple arthroscopy, you're looking at weeks, while a joint replacement takes months. But the path to success remains exactly the same.
What about Osteopathy?
After years of dealing with a painful knee, your hips, pelvis, feet, and back have likely adapted to compensate—and these patterns don't just vanish once you get your new implant. This is where osteopathy comes in to elevate your rehab: it targets and resolves the limitations those years of strain have left in your surrounding joints and muscles.
Aligned with your surgeon’s custom plan, in perfect sync with your medical team
Your knee rehab is designed to align with your surgeon's specific post-op protocol; simply bring it along with your referral and surgical report to your first session. If any questions arise during your recovery, we'll consult directly with your doctor. You can find a complete overview of our post-surgical rehabilitation and our in-clinic training facilities on the overview page.
Your first appointment: how we start
To ensure your rehabilitation seamlessly follows your discharge from the clinic, it is best to get in touch with us before you leave; this allows us to schedule your first appointment directly. Otherwise, you will almost always find a short-notice appointment with us, and if you don't see a suitable one online, just call us: 044 545 03 03.
Bring what you have: the medical referral, the surgical report if available, and the post-treatment plan. We will review your documents, assess your initial condition with measurable metrics, and translate your surgeon's protocol into a plan that perfectly fits your lifestyle. This way, from hour one, you'll know exactly where you stand and what steps lie ahead.
And because those first few weeks require a consistent rhythm, it is best to schedule your follow-up appointments directly as a series with us—usually two per week for the first four to six weeks. You can cancel up to 24 hours in advance, but finding a new slot quickly is not always as easy.
When to see your doctor
Post-operative complications are rare. However, seek immediate medical evaluation if you experience any of these signs:
Fever, combined with the operated area becoming hotter, redder, and more painful: a potential sign of infection.
One-sided swelling, tension, or tenderness in your calf or leg: a possible thrombosis, especially during periods of low activity.
A sudden, significant loss of strength or sensation compared to previous days: this requires a medical assessment before your next therapy session.
Pain that increases day by day despite resting: your surgeon needs to evaluate this.
Coverage Guaranteed
Physiotherapy is covered by your basic health insurance with a doctor's referral. In the event of an accident, your accident insurance or the accident coverage of your health insurance company will step in. For Medical Training Therapy (MTT), prior cost approval from your health insurance company is required, which we will clarify with you before we get started. You can book Osteopathy directly without a referral; most supplementary insurance policies for alternative and complementary medicine will contribute to the costs.
Whether it's physiotherapy or osteopathy: you are always welcome as a self-payer, with absolutely no compromise on the quality of your treatment or time. You can find the cost of your treatment under Rates and Cost Coverage.
