Treatment of Gonarthrosis by Total Knee Arthroplasty

ABSTRACT

Gonarthrosis is a progressive chronic arthropatic disease of the knee which includes degenerative changes of the knee cartilage and hypertrophic changes of the bone tissue around of the articulare surface. The onset of the disease is insidious and vague. As the condition progresses, clinical signs became more significant like weakness of musculus quadriceps, flexion contracture of the knee joint, and valgus or varus deformity of the knee. Radiological changes of the osteoarthritic knee are narrowing of the joint space, sclerosis of the subhondral bone, osteophyte formation and in the terminal stadium cystic degeneration of the subhondral bone. In period from the 30.08.1999 to 30.08.2004 year at the Clinic of the Orthopaedics and Traumatologicy of Clinical Center of the Nis were treated 10 patients with gonarthrosis by total replacement artrhoplasty of knee joint. In all patients implant was produced by the company Jonhson-Johnson. After undergone replacement surgery of the knee joint, patients were relieved from the continous pain, and had stabile and secure gait with optimal movement of the replace knee joint in all direction. Excellent and very good results in the treatment of the osteoarthritic knee by total replacement artrhoplasty were reported in nine patients, and there were postoperatively infection of the wound only in one patient.
