The Variable Axis Knee Prosthesis offers stability and firm fixation for diverse knee issues. Proper patient selection is crucial for successful long-term outcomes in knee replacement surgery.

Area of Science:

Orthopedic surgery
Biomedical engineering

Background:

Knee joint impairments necessitate advanced prosthetic solutions.
Minimizing prosthetic loosening is a key challenge in knee replacement.

Purpose of the Study:

To evaluate the long-term effectiveness of the Variable Axis Knee Prosthesis.
To assess the prosthesis's ability to manage complex knee abnormalities and reduce complications.

Main Methods:

A seven-year retrospective analysis of patients receiving the Variable Axis Knee Prosthesis.
Assessment of prosthesis stability, fixation, and management of various knee conditions.

Main Results:

The Variable Axis Knee Prosthesis demonstrated effectiveness in providing stability and firm fixation.

Related Experiment Videos

Successful management of diverse abnormalities including failed prostheses, flexion contractures, and osteoporotic bone.

Patellar alignment identified as critical for optimal outcomes.

Conclusions:

The Variable Axis Knee Prosthesis is effective for a wide range of knee problems, including complex cases.
Adherence to indications and contraindications is essential for successful knee replacement.
Long-term results are comparable or superior to total hip replacement.
