Functional evaluation of patients fitted with total knee prostheses

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Geriatric medicine

Background:

• Degenerative and inflammatory knee joint diseases are prevalent in the elderly population.
• Total knee joint replacement with prostheses is a favored treatment for severe degeneration, aiming to relieve pain, correct deformities, and restore mobility.
• Advancements in materials and understanding of articular mechanics have improved knee prosthesis design and efficacy.

Purpose of the Study:

• To evaluate the functional outcomes of patients with knee prostheses.
• To compare the biomechanical behavior of knee prostheses with the physiological function of a natural human joint.
• To initiate an assessment using a gait analysis system for patients fitted with knee prostheses.

Main Methods:

• Utilized a gait analysis system to assess patients who have received knee prostheses.
• Focused on evaluating the biomechanical performance and functional recovery post-surgery.

Main Results:

• Initial impressions suggest a need for further investigation into the comparison between current knee prostheses and natural joint biomechanics.
• The study provides preliminary data from gait analysis of patients with knee prostheses.

Conclusions:

• While current knee prostheses offer significant clinical benefits, there is a perceived gap compared to the biomechanical sophistication of natural joints.
• Further gait analysis is warranted to fully understand and potentially improve knee prosthesis function.
• This study marks the beginning of an evaluation into the biomechanical performance of knee prostheses.
