Increasing experiences in determining the indication for UKA and improvements in design and materials of the prosthesis led to better results. The AMC-Uniglide has an unconstrained mobile bearing with congruent area contact. This ensures complete freedom to rotate and slide upon one other with physiologic kinematic and low intrinsic stability

Minimal-invasive technique 30 patients with minimal-invasive AMC-Uniglide implantation technique were compared with 30 conventional implanted AMC’s and 30 total knee replacements in regard to rehabilitation and accuracy of implantation. 361 AMC-Uniglides 361 consecutive patients were investigated after AMC-Uniglide implantation. The mean duration of follow-up was 5.5 (2.3–12.5) years. Patients were reviewed using the American Knee Society Rating System. The roent-geno graphic analyses were performed with the American Knee Society Evaluation System.

The clinical results of the investigated patients demonstrate that the AMC-Uniglide is a successful concept with a safe anchorage of the prosthesis and a good durability of the mobile bearings. An advantage of minimal invasive technique with regard to a reduced time of rehabilitation was found. The accuracy of implantation was comparable between the conventional and the minimal-invasive technique

Introduction: Increasing experiences in determining the indication for UKA and improvements in design and materials of the prosthesis led to better results. The AMC-Uniglide has an unconstrained mobile bearing with congruent area contact. This ensures complete freedom to rotate and slide upon one other with physiologic kinematic and low intrinsic stability.

Material and Methods:

Minimal-invasive technique 30 patients with minimal-invasive AMC-Uniglide implantation technique were compared with 30 conventional implanted AMC’s and 30 total knee replacements in regard to rehabilitation and accuracy of implantation.

361AMC-Uniglides 361 consecutive patients were investigated after AMC-Uniglide implantation. The mean duration of follow-up was 5.5 (2.3-12.5) years. Patients were reviewed using the American Knee Society Rating System. The roentgenographic analyses were performed with the American Knee Society Evaluation System.

Results:

Minimal-invasive technique The comparison of 30 minimal-invasive UKA with 30 conventional UKA and 30 total knee replacements show an advantage of minimal invasive technique with regard to a reduced time of rehabilitation. The accuracy of implantation was comparable between the conventional and the minimal-invasive technique.

361 AMC-Uniglides Ninety-five percent of patients had no pain or slight pain at the latest follow-up, ninety-two percent had good or excellent clinical outcome. Three knees were revised for mobile bearing dislocation after medial UCA and three for lateral mobile bearing dislocation after lateral UCA. Five revisions because of component loosening were performed and there was one case of deep infection.

Conclusion: The clinical results of the investigated patients demonstrate that the AMC-Uniglide is a successful concept with a safe anchorage of the prosthesis and a good durability of the mobile bearings. An advantage of minimal invasive technique with regard to a reduced time of rehabilitation was found. The accuracy of implantation was comparable between the conventional and the minimal-invasive technique.
