Knee surgery

Knee surgery is a highly specialised field within orthopaedic surgery and deals exclusively with treatment of the knee joint.

Ensuring the best possible treatment of a knee injury requires specialists with a meticulous understanding of the workings of the knee, gained over many years of experience.

Knee arthroscopy


In our clinics, we offer you a wide range of therapy and treatment options, from conservative, pain-relieving therapies to surgical interventions.

  • Arthroscopic procedures (arthroscopy) for the early stages of osteoarthritis, with cartilage smoothing and removal of new bone formation and painful plicas
  • Injections of hyaluronic acid, cortisone or autologous blood
  • Artificial knee joints/knee prosthesis (surface replacement, partial or total prosthesis)
  • Revision of knee prostheses and treatments for painful artificial knee joints
  • Axis correction at the knee in the case of bow legs and knock knees
  • Anterior and posterior cruciate ligament replacement following a cruciate ligament tear
  • Treatment of tendon and ligament injuries in the knee
  • Cartilage and bone transplantation in the case of cartilage damage
  • Meniscus surgery (after meniscus tear or meniscus damage); meniscus suture
  • Operations on the kneecap (patella)
  • Second opinions on all knee problems


What are the most common causes of knee problems?

Knee problems can have many causes. Common causes include injuries, excessive or incorrect strain on the joint, or weak muscles in the knee.

What injuries cause knee pain?

Pain or injuries that lead to knee surgery often affect the cartilage, menisci or ligaments. However, injuries are not just the result of hard physical work or sports. Sudden stopping movements and a combination of flexion and twisting of the knee can also lead to injuries, such as:

  • meniscus tear
  • tendon tears
  • cruciate ligament tear
  • bruising

What is the most common cause of knee pain?

In active people, overexertion of the ligaments and tendons, as well as bursitis, can often cause problems with the knee. Meniscus injuries and damage to the cruciate ligament or cartilage also cause knee problems. In older adults, most knee problems are caused by symptoms of wear, such as osteoarthritis of the knee.

What can be done preventatively to avoid knee surgery?

At first glance, exercise may seem to be a risk factor for knee injuries and knee pain. However, regular exercise trains the muscles around the knee and stabilises the joint.

There are also various sports that are especially gentle on the joint. These includes classic cross-country skiing, swimming, cycling or fitness training on certain gym equipment. A healthy and varied diet also contributes significantly to the prevention of knee problems.

What is jumper’s or runner’s knee?

The condition known as jumper’s knee occurs when the ligaments are overexerted due to repeated jumping movements or sudden changes in direction. This overexertion can lead to minor injuries to the tendons on the lower edge of the kneecap. New connective tissue forms there and the nerves and blood vessels cause exertion-induced pain.

Runner’s knee is most common in long-distance runners. The pain that occurs on the outside of the knee is caused by tendon problems. The group of tendons that start at the pelvis and extend along the side of the thigh to the tibial plateau repeatedly rub against the knee joint during movement. This strains the tissue and leads to inflammation. 

When is knee surgery recommended?

First of all, the knee problem must be thoroughly investigated. Depending on the cause, it may be possible to achieve good results with conservative measures (e.g. medication or physiotherapy). If the symptoms are so severe that there is persistent pain and the patient’s quality of life is compromised, then surgery should be considered.

Osteoarthritis is a gradual process with increasing levels of pain. When do you need a knee prosthesis?

If your quality of life is restricted or your everyday life is full of pain and uncertainty, a knee prosthesis can help. An artificial knee joint can provide freedom from pain and restored mobility. The lifespan of an artificial joint is usually 10 to 15 years. There are various factors that can limit the lifespan of an artificial joint, such as: obesity, activity, increased osteoporosis, infections, allergies, joint instability and accidents.
