[Total knee joint replacement with a rotating hinge endoprosthesis in light of late results].

Results of 15 total knee replacements with rotating hinge endoprosthesis in 13 rheumatoid patients with an average follow-up of 7 years and 11 months are presented. C.R.S. point scale served to assess results. As to pain, range of motion, stability and alignment good results have been achieved in all cases. Ability to ambulate was diminished due to general condition of rheumatoid patients (8 of them had total hip and/or contralateral total knee replacement). Results of hinge tkr with the same follow-up yielded 33% failures. In conclusion rotating hinge tkr is markedly better than hinge type knee arthroplasty.

[Some aspects of kinematic condylar knee replacement].

On the basis of review of results of 60 kinematic condylar knee replacements in 49 patient and the literature the principles of surgical techniques in varus and valgus deformities of the knee and patellar subluxation have been presented. The authors substantiated their opinion of contraindication for patellar replacement. Tibial components (AJ, PCR, Total Condylar) have been discussed and data on frequency of their use provided. Instrumentation supplied does not guarantee the precision desired, the surgeons experience is indispensable.

[Long term results of total hip arthroplasty in patients with ankylosing spondylitis].

The results of total hip arthroplasty with the use of 5 different types of prostheses in 63 hips of 38 patients were presented. The range of follow up was from 7 to 14 years. The evaluation was done with the aid of M. d'Aubigné--Postel criteria and radiological assessment. Patients opinion and his ability to work was taken into consideration. The pain was reduced most significantly. Remarkable improvement was found in the gait and in the range of hip motion. In 24.5% of patients possible, probable or evident radiographic loosening was found. Ectopic ossifications of different degree were found in 38.8% of patients, mostly in hips previously operated on or severely destroyed. Ankylosing hips improved in movement to lesser extent. No deep infection was observed in early or late follow up.

[Should trochanteric osteotomy be performed during total hip replacement?].

Advantages and disadvantages of trochanteric osteotomy were discussed. 716 total hip arthroplasties were performed in 594 patients. Trochanteric osteotomy was done in 79 hips (11%) of 68 patients: 39 cases of rheumatoid arthritis, 17 cases of ankylosing spondylitis, 9 cases of osteoarthritis and 3 cases of various conditions. In 73 hips the trochanter was reattached by Charnley, Coventry or Amstutz method; in remaining cases an original method was used. 42 hips in 36 patients were followed up. The results were evaluated on the basis of clinical, radiographic assessment and opinion of the patient. Trochanteric non-union was found in 3 hips (7.1%), delayed union in 2 cases (4.7%), the wire loop was broken in 6 hips (14.2%) with no disturbance of trochanteric union. The authors recommend Trochanteric osteotomy only in cases of difficult access to the joint or in order to prevent soft tissue damage in instances of difficult anatomic conditions.

[Total knee arthroplasty with GSB endoprosthesis (introductory information)].

The construction of GSB prosthesis and surgical technique was presented. The prosthesis having no fixed axis enables flexion and extension as well as shifting and rolling. Unlike the other systems GSB implantation does not require vast resection of femoral and tibial condyles. This is very important in case of failure and necessity of removal of the prosthesis--the revision arthroplasty or arthrodesis does not result in great shortening of the extremity. GSB prosthesis was implanted by the authors in 25 knees of 23 patients. The average follow up was 9 months. In all cases results were good, complications were not observed. The authors conclude that GSB prosthesis deserves wider propagation in surgical treatment of advanced destructive changes in the knee, especially in rheumatoid patients.

[Development of arthroplasty of the knee joint using endoprostheses].

The development of endoprosthetic arthroplasty of the knee joint since the beginning of this century has been presented. The most often used endoprostheses have been discussed. Attention has been drawn to the disadvantages of hinge endoprostheses, that were replaced by new modified types of endoprostheses including rotation of the joint and consisting in the union of metal with polyethylene. Some examples of new types of endoprostheses have been described, the multiaxial ones simulating physiological movements of the joint being the most interesting. The most often used epicondylar endoprostheses and partially constrained have been presented, pointing out the tendency to use cementless endoprostheses of the knee. The paper ends with a simplified division of over 400 types of knee endoprostheses produced on the world up to now.
