After knee replacement (Knee TEP) or hip replacement (Hip TEP), many patients wonder whether and when they can resume sports activities, especially swimming. Often, there is uncertainty because numerous myths and outdated behavioral rules still circulate, advocating unnecessary restrictions. However, swimming can not only be harmless but also highly beneficial for recovery and long-term mobility. In this article, we clarify the most important questions and show why patients should not be deterred by outdated recommendations.

Myths surrounding swimming with knee replacement and hip replacement

Myth 1: "Swimming puts stress on the implants"

This misconception is based on the assumption that the movements involved in swimming could exceed the resilience of the artificial joint. In fact, swimming is one of the most joint-friendly sports. Due to the buoyancy of the water, the body's own weight is almost neutralized, so the joints are subjected to hardly any pressure or shocks.

Myth 2: "Pool hygiene poses infection risks"

Many patients avoid swimming pools out of fear of infection through the skin or surgical site. Studies show that thorough wound healing after surgery, combined with regular hygiene measures, provides sufficient protection. Once the scar has healed and the treating physician permits swimming, the water quality in swimming pools does not pose a significant risk.

Myth 3: 'After surgery, all swimming should be avoided'

Some patients still receive recommendations from individual healthcare professionals to avoid swimming altogether. This way of thinking is no longer in line with the current state of medicine. Exercise therapies like swimming actively contribute to improving mobility and strengthening muscles, and today, they are not associated with a risk of complications or discomfort.

Why Swimming with Knee and Hip Prostheses is Safe

Scientific Basis

Recent studies clearly show that swimming has no negative impact on the longevity or stability of joint prostheses. On the contrary: water gymnastics and swimming are among the best activities to promote joint function postoperatively.

Benefits of buoyancy in water

The buoyancy reduces the joint stress to a minimum. This means that patients can perform movements that would be either painful or limited due to gravity on land. This makes swimming an optimal sport for patients with knee or hip prostheses.

Muscle Building and Stabilization

Regular swimming sessions promote the development of muscle mass, especially the surrounding support muscles. Strong muscles additionally stabilize the artificial joint and improve functionality.

The medical benefits of swimming after joint replacement

Pain reduction

Immersing in water has a relaxing and circulatory promoting effect. This not only leads to relief of the joints, but also to a sustained reduction in pain.

Improved mobility

The gentle movement in water helps to loosen adhesions in the tissue and restore mobility.

Cardiovascular Health

Swimming not only offers benefits for the joints but also trains the cardiovascular system. This is particularly important for patients with artificial joints, as overall fitness also promotes healing.

When can patients start swimming after surgery?

Consider Healing Phases

The exact time when swimming is possible again depends on individual factors. However, the following general guidelines apply:

Early phase (0–6 weeks): Directly after surgery, patients should refrain from water activities until the surgical scar is fully healed.

Rebuilding phase (6–12 weeks): First gentle movements in the water, such as water gymnastics or breaststroke, are often already possible.

Stabilization phase (from 12 weeks onwards): Regular swimming sessions can be done without restrictions.

Consultation with the doctor

Patients should consult their treating orthopedic surgeon before starting to swim. This ensures that there are no contraindications.

The best swimming techniques for patients with knee or hip prostheses

Breaststroke

Breaststroke is a popular choice for many patients, but a gentle technique should be used to avoid unnatural movements in the knee and hip area. Neither after knee replacement nor after hip replacement does the frog movement in breaststroke pose a significant risk today.

Backstroke and freestyle

Backstroke and crawl are considered particularly gentle on the joints, as they do not require rotational movements and keep the hip and knee in a neutral position.

Aquajogging

Aquajogging is a good alternative for those who feel uncertain about swimming. With the help of swimming belts, running movements can be performed in the water.

Conclusion – No fear of water after joint replacement!

Patients with knee or hip prostheses should not be deterred by outdated recommendations or anxious myths. Swimming is a safe and effective sport that offers numerous benefits for recovery and long-term health. After consulting with the doctor and adhering to the healing phases, enjoyable swimming is possible after knee or hip replacement - so get in the water!
