Clinical and functional comparison of uni- and bicondylar sledge prostheses.

The aim of the present study was the evaluation of differences in clinical results, proprioceptive performance and gait in patients with unicondylar and bicondylar sledge prostheses of the knee. In a retrospective study, 17 patients with unicondylar sledge prostheses were compared with 15 patients with bicondylar sledge prostheses. Clinical examination was rated using HSS, Knee Society, and patellar scores and a visual analogue scale for pain.

Muscle strength in patients with unicompartmental arthroplasty.

Objective: The aim of the current study was to evaluate the isokinetic strength of the knee in patients with unicondylar prostheses, to compare these results with healthy control subjects of the same age, and to correlate these results with clinical scores.

Design: Seventeen patients were examined an average of 21.5 mos after surgery.

Clinical and functional comparison of bicondylar sledge prostheses retaining all ligaments and constrained total knee replacement.

Objective: Comparison of different total knee replacements regarding clinical and functional differences with respect to gait and electromyographic analyses.

Design: Retrospective, comparative, clinical and functional study.

Methods: Three groups (control group of 11 healthy subjects, 15 patients with bicondylar sledge prostheses retaining all ligaments (cemented unicondylar prostheses in both the medial and lateral compartment), 15 patients with constrained total knee replacement sacrificing all cruciate and collateral ligaments (cemented total knee prosthesis with intramedullary stems and a large intercondylar tibial post) were compared by clinical evaluation using a number of clinical evaluation scores, a pain scale, surface electromyographic examinations of the lower limb, and gait analysis.

Quality of life and gait after unicondylar knee prosthesis are inferior to age-matched control subjects.

Objective: Evaluation of quality of life, gait pattern, and muscle activity after implantation of unicondylar sledge prostheses in comparison with control group.

Design: A total of 17 patients were examined at an average follow-up of 21.5 mo after implantation of unicondylar sledge prostheses.

Proprioception with bicondylar sledge prostheses retaining cruciate ligaments.

The current study was designed to evaluate the proprioceptive performance of the knee after implantation of bicondylar sledge prostheses in comparison with contralateral knees and knees of healthy control subjects. After implantation of a sledge prosthesis in the medial and lateral condyles of a knee retaining all ligaments, 15 patients were evaluated clinically and by proprioceptive testing. Clinical examination was done using common scoring systems.

Proprioceptive function, clinical results, and quality of life after unicondylar sledge prostheses.

Objective: Evaluation of proprioceptive performance and quality of life after implantation of unicondylar sledge knee prostheses in comparison with normal control subjects.

Design: A total of 17 patients were examined after implantation of unicondylar sledge prostheses. Clinical examination was performed, quality of life was assessed, and proprioceptive performance was examined.

[Correlation of electromyography and clinical results after bicondylar knee joint prosthesis implantation].

Aim Of The Study: To investigate clinical findings in patients receiving bicondylar sledge prostheses, and their correlation with electromyographic measurements in comparison with healthy volunteers.

Material And Methods: An average of 31.9 months after implantation of a bicondylar sledge prosthesis, 15 patients were clinically examined and compared with 11 control subjects.

[Results of bicondylar sledge prostheses with special reference to the gait pattern].

Aim: To establish whether the clinical results obtained with bicondylar sledge prostheses correlate with clinical findings, and whether clinical results influence gait pattern.

Material And Methods: 15 patients with bicondylar sledge prostheses were compared with healthy controls. The clinical examination was documented using the HSS, Knee Society, Tegner, and patella scores, and the Visual Analogue Scale.
