Prehabilitation Before Knee Surgery: How Training Can Help

Preparation for knee replacement can begin several weeks before the operation. During this time, knee pain may cause you to walk and move less, leading to a gradual loss of strength. This can make early recovery tasks, such as standing up, walking, and climbing stairs, more difficult.

Prehabilitation uses the time before surgery to prepare for these demands. A programme adapted to your current abilities can help maintain strength and mobility while allowing you to practise movements needed after the operation. It also gives you a clearer idea of what to expect when rehabilitation begins.

What Is Prehabilitation?

Prehabilitation, often shortened to prehab, is the preparation carried out before a planned operation. For knee replacement, it focuses on strengthening the muscles and improving joint flexibility before surgery. Rehabilitation begins afterwards and supports recovery as the knee heals.

Prehabilitation can also include practical planning for the first weeks at home. This may involve arranging crutches or a walker, making the home safer, and organising help with cooking, bathing, or laundry while mobility is limited.

Why Is Training Before Knee Surgery Worthwhile? 

Knee osteoarthritis often makes movement painful, which can lead to less activity and a gradual loss of leg strength. The quadriceps at the front of the thigh is especially important because it supports standing up, walking, and climbing stairs.

Prehabilitation helps maintain or improve these abilities before surgery. This may make early tasks after the operation feel more manageable and support progress during the first stage of rehabilitation. The benefits vary according to your physical condition, general health, and the course of the operation.

Preoperative physiotherapy ensures that the exercises and preparation are suited to your current abilities and the demands you are likely to face after surgery.

What Happens During Knee Replacement Surgery? 

During surgery, the damaged cartilage and bone are removed and replaced with prosthetic components, leaving the healthy part untouched. A common reason for this procedure is advanced osteoarthritis, which can make movement painful and difficult. Recovery then focuses on restoring knee movement, rebuilding strength, and learning to walk safely. Prehabilitation prepares you for these early rehabilitation tasks before the operation takes place.

What Does Prehabilitation Include?

Prehabilitation combines physical training with practical preparation for surgery. The program begins with an assessment to identify which areas of the knee need the most attention.

Exercise may include strengthening the thigh and other leg muscles, improving knee movement, and practising a stable walking pattern. The intensity should match the knee’s current capacity and be adjusted if pain or swelling increases.

Practical preparation helps make the first days after surgery easier. This may involve practising with crutches, learning safer ways to stand up or use stairs, and understanding what to expect during early rehabilitation. Nutrition, pain management, and mental preparation may also be discussed when relevant.

When Should Prehabilitation Begin? 

Prehabilitation often begins around six weeks before knee replacement surgery. This allows enough time to practise the exercises and build a regular routine. A shorter program may still be worthwhile if the operation is already approaching.

How much exercise you can manage depends on your current pain, knee mobility, strength, and overall health. A physiotherapist can adjust the exercises so they help build strength without leaving the knee more painful or swollen afterwards. 

Methods from sports physiotherapy may also be used to build strength and physical capacity in a controlled way. These methods are adapted to the needs of people preparing for surgery, including those who do not participate in sport.

Prepare for Knee Replacement Surgery with PhysioWelt

At PhysioWelt in Schlieren, prehabilitation begins with an assessment of how your knee currently moves and functions. Your physiotherapist then creates a program based on the demands you are likely to face after surgery, while taking your pain and general health into account.

Support can continue into postoperative rehabilitation, allowing the treatment plan to develop as your condition changes. Because the exercises and walking aids have already been practised, the first sessions after surgery can build on movements that are familiar to you.

Start Preparing Before Your Knee Surgery

Prehabilitation gives you time to prepare for the movements and exercises that will become important after knee replacement surgery. Even a short program may be useful when it is adapted to your current abilities, although it does not replace rehabilitation after the operation.

Frequently Asked Questions (FAQ)

How long before knee replacement surgery should I start training?

Aim to start once the operation has been planned and your medical team has confirmed that exercise is appropriate. Many prehabilitation programmes start six weeks prior to the surgery, although the available preparation time will depend on your surgery date. 

Is a total knee replacement surgery a major operation?

Yes. Although knee replacement is performed regularly, it remains a major operation that requires a structured period of recovery. Preparing beforehand may make the first rehabilitation tasks feel more familiar. 

What are some things you can no longer do with a total knee replacement?

Many everyday and leisure activities become possible again after rehabilitation. Low-impact activities are generally easier on the replacement, while sports involving repeated jumping or heavy impact should be discussed with the medical team. 

How long does it take to recover after a total knee replacement?

Full recovery usually takes around six to twelve months. However, many people can return to most normal daily activities within the first three months. The exact timeline depends on individual progress and how the knee responds to pre- and postoperative rehabilitation. 

Does the health insurance cover prehabilitation?

Coverage depends on the treatment, medical prescription, and terms of the insurance policy. Before beginning prehabilitation, confirm the details with your doctor, physiotherapy provider, or health insurance.
