Coxarthrosis & hip prosthesis

What is coxarthrosis?

Coxarthrosis (hip joint arthrosis) is a disease in which the hip joint or the cartilaginous joint surfaces of the hip joint increasingly wear out. Risk factors are congenital deformities, a CAM deformity, previous injuries and operations, inflammatory diseases and metabolic diseases.

What kind of complaints do you have?

The main symptoms of coxarthrosis are pain in the affected hip joint, a feeling of stiffness and restricted mobility. At first, the complaints only occur during exercise. However, as the disease progresses, the pain can also be felt at rest.

Is an operation always necessary?

The option of non-surgical osteoarthritis therapy should always be considered first.

Muscle building and weight loss with increased exercise and a change in diet should be a cornerstone. Physiotherapy (remedial gymnastics) is a useful addition.

Therapy with anti-inflammatory injections, cartilage cures with hyaluronic acid and autologous blood therapy (PRP) can help to relieve pain in the knee joint up to moderate osteoarthritis and slow the progression of the disease. The exact course of therapy is based on the causes and severity of the coxarthrosis and other factors such as the patient’s age and activity level.

When does joint-preserving surgery make sense?

As part of a CAM deformity, bony cusps are formed at the transition from the femoral head to the femoral neck. This can result in pain from an injury to the joint lip (labrum) and increasing cartilage wear. Joint-preserving surgery is possible if the coxarthrosis is not too advanced.

When does an artificial joint replacement / hip prosthesis make sense?

If the pain does not improve and the osteoarthritis progresses, an artificial hip joint should be used. The timing of the operation is based on the severity of the complaints. The main criteria are a significant reduction in quality of life and mobility, increasing restrictions on the movement of the hip joint, pain at night and regular use of painkillers.

What is a hip prosthesis?

A hip prosthesis is an artificial replacement for the worn out cartilaginous hip joint surface. Only the worn parts are replaced. Surrounding structures such as tendons and muscles are completely preserved.
A hip prosthesis consists of 4 parts. A titanium socket is anchored in the pelvic bone. An insert made of ceramic or a highly cross-linked polyethylene is fitted into the socket as a sliding pair. A titanium shaft is inserted into the thigh bone and finally a ceramic head is attached to the titanium shaft.

The socket and the shaft are inserted precisely into the bone bed. The surface properties of the prosthesis lead to ingrowth into the bone. The sliding pair (head and insert) are made of modern, very durable materials. As a result, there is only minimal, irrelevant wear. As a result, the size of the head could be increased significantly, which massively reduced the complication of a hip dislocation.

Only hip prostheses from well-known companies with excellent long-term results are used at the Speising Orthopedic Hospital.
