Using endoprosthesis to replace damaged joints is among the most successful and sought after orthopedic surgeries. Hip and knee joints are most often replaced, but that's not the only areas that endoprothesis are considered a good solution.
Endoprosthesis and artificial joints are placed i.e. in the elbow, shoulder, ankle, as well as hands, though far less frequently. The shoulder joint is replaced most often in elderly patients, while replacement of the elbow joint is done in case of severe injuries, such as motor transport accidents where bones and joints suffer from multiple fractures.
Osteoporosis and degenerative bone diseases can speed some processes in the body and require surgical intervention in the treatment of joint problems. Professional athletes and people who perform repeated identical movements and are subject to constant, continuous load on the joints suffer more often from pain and resort to surgical treatment of joint problems.
Endoprothesis is imposed on a number of other causes, such as congenital or acquired diseases, dysplasia or improper formation of the femoral head, various inflammatory processes, tumors, trauma, metabolic disorders, inflammatory arthropathies, gout, osteoporosis, rheumatoid arthritis. All these diseases infect bone structure differently, as most seriously affected are precisely knee and hip - the most common endoprosthesis structures.
As for the durability of artificial joints - there are many factors that must be considered.
Specialists say that once implanted artificial joint can withstand a lifetime without re-operation or costly replacement of the implant. However, there are individual cases and certain conditions requiring repeating of the procedures. Some patients require further reduction of internal prosthesis after operation. In certain cases loosening of the connection between the implant and the existing bone structure can occur. Due to differences in the ways of attaching the prosthesis to the bone, it is often impossible to give a definite forecast for such a coincidence.
Natural processes, such as oxidation n the tissues around the prosthesis may cause gradual destruction of the connection between the implant and the bone. Experts warn that such an option exists, although it occurs in only about 10% of cases. Among the main hypotheses why this is happening is the idea of so-called oxidative stress.
In more than 80% of patients with implants (artificial joints, internal prosthesis) serve faithfully and seamlessly for life.
Living with an artificial joint - how to prevent problems and complications
For best results and trouble-free healing of an artificial joint the patient should start rehabilitation and light movement as soon as the first few days of postoperative hospital stay - under the supervision of a physiotherapist. Rehabilitation continues at home or in a specialized facility for treatment and rehabilitation. Antithrombotic prophylaxis is important and should be continued postoperatively.
The physical activity of the patient with an endoprosthesis should be dosed carefully, and never exceed levels that can jeopardize the integrity and status of the implanted artificial joint. Avoid contact sports, intense exercise, running, weightlifting, etc.
