JOINT REPLACEMENT: KNEE REPLACEMENT
Knee osteoarthritis

The knee joint is often depicted as a simple hinge joint, but on closer inspection it is a highly complex joint with a rotational-gliding mechanism and many important ligaments. Treatment should therefore be carried out by a knee specialist.
Due to the high stresses to which the knee joints are subjected, wear and tear is very common over the course of a lifetime, leading to significant discomfort and limitations in quality of life. Early sports injuries, misalignments, or being overweight significantly contribute to this development.
Unlike the hip joint, a so-called ball-and-socket joint where the entire joint is always affected, only individual compartments (e.g., on the inside or behind the kneecap) can be treated in the knee joint.
As part of the treatment for osteoarthritis of the knee (arthrosis of the knee), surgical procedures may also be necessary in addition to conservative measures:
- JOINT-PRESERVING OPERATIONS ON THE KNEE JOINT (CORRECTION OF MISLASES AND ANATOMICAL VARIETY, MOSTLY BY MEANS OF MINIMALLY INVASIVE JOINT SURGERY (ARTHROSCOPY), PARTLY ALSO BY MEANS OF JOINT OPENING (MINI-OPEN).
- Endoprosthetic surgery on the knee joint (replacement of damaged joint edges with artificial implants made of metal and highly cross-linked plastic).
Artificial knee joints are classified as either total or partial replacements. I will carefully determine which prosthesis is suitable for you beforehand, based on a clinical examination, as well as X-rays or MRI scans.
Artificial joint replacement is a very successful and reliable treatment option in the advanced stages of osteoarthritis.
- Cemented or cementless partial joint replacement using lateral joint replacement (medial or lateral)
- Cemented partial joint replacement using PFJ or Wave prosthesis ( patellar resurfacing )
- Cemented total surface replacement (classically: the " knee prosthesis ")
- EXTRA stabilizing implants or axis-guided prostheses
- INLAYS as a meniscus replacement made of
highly cross-linked polyethylene
Professional knee replacement in Mainz: Your expert for artificial knee joints
Advanced osteoarthritis of the knee joint can lead to significant pain and a severe reduction in quality of life. When conservative treatment methods such as physiotherapy or medication are no longer sufficient, a knee replacement (TKR) is a proven and effective solution to restore your mobility and freedom from pain. At the ENDOPROTHETICUM Rhein-Main, Prof. Dr. med. Karl Philipp Kutzner is your highly specialized contact person for knee replacement .
What is a total knee replacement and when is it necessary?
A total knee replacement, or TKR for short, is a surgical procedure in which the worn surfaces of the knee joint are replaced with high-quality implants made of metal and plastic. This joint replacement mimics the natural function of the knee and restores smooth and pain-free movement. Such a procedure is generally recommended when the articular cartilage is so severely damaged by osteoarthritis (gonarthrosis) that the patient suffers from persistent pain, restricted movement, and a loss of quality of life.
Reasons for an artificial knee joint
- Severe, persistent knee pain, even during rest
- Significant restriction of walking distance and everyday activities
- Leg misalignments such as bowlegs or knock-knees
- Failure of conservative treatment measures
- Advanced radiologically confirmed joint wear

If you are suffering from knee problems and would like to learn more about the possibilities of a total knee replacement or an artificial knee joint , schedule a consultation. Prof. Dr. Kutzner and his team at the ENDOPROTHETICUM Rhein-Main in Mainz look forward to helping you overcome your pain and regain a new quality of life.

During the operation, access to the knee joint is gained from the front, and the knee is repeatedly flexed and extended. The lateral and medial collateral ligaments, and in some cases the cruciate ligaments, are carefully protected during the procedure.
To minimize pain after the operation, pain medication is administered via injections during the procedure (LIA = local infiltration anesthesia).

SLED PROSTHESIS
Partial replacement is possible in all areas of the joint, but is most commonly performed on the inner side and is often referred to colloquially as a unicompartmental knee replacement . Similar to a total knee replacement, the damaged cartilage is replaced with a new surface, and a plastic inlay is inserted between the two. For a partial knee replacement, all ligament structures, especially the cruciate ligaments, must be largely intact.
SURFACE REPLACEMENT
KNEE REPLACEMENT (ARTIFICIAL KNEE JOINT)
The artificial knee joint replaces the cartilage surface destroyed by osteoarthritis. The underlying bone of the femur and tibia remains intact. Some compare a modern artificial knee joint to a
crown on a tooth; the precise term is
bicondylar resurfacing. Between the new surfaces of the femur and tibia is an inlay made of a specially hardened white plastic, visible in X-rays as a gap between the metal components.

SMALL IMPLANTS / REPLACEMENT OF THE KNEE JOINT
Impaired mobility or instability, as well as abnormal kneecap shape (dysplasia), can lead to cartilage damage and osteoarthritis isolated to the patellofemoral joint. If the other compartments are free of osteoarthritis, an
isolated partial knee replacement of the posterior surface of the patellofemoral joint is a possibility.
