Medium-term Results Evaluation between Gender-Specific x Conventional Total Knee Arthroplasty Prostheses

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Rehabilitative Medicine

Background:

• Total knee arthroplasty (TKA) is a common procedure for knee osteoarthritis.
• The development of gender-specific prostheses aims to improve patient outcomes.
• Limited long-term comparative data exists for gender-specific versus conventional TKA.

Purpose of the Study:

• To compare the 5-year postoperative functional outcomes of TKA using gender-specific prostheses versus conventional prostheses.
• To evaluate the efficacy of gender-specific implants in improving functional results after TKA.

Main Methods:

• Retrospective study design.
• Inclusion of 30 patients undergoing TKA, with 15 in each group (gender-specific vs. conventional).
• Functional assessment using Knee Injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities arthritis index (WOMAC), The Knee Society Clinical Rating System (KSS), and range of motion (ROM).

Main Results:

• No statistically significant differences were observed in KOOS, WOMAC, or KSS scores between the two groups.
• Range of motion (ROM) measurements also showed no significant differences between patients receiving gender-specific or conventional prostheses.
• Functional outcomes were comparable at the 5-year postoperative mark.

Conclusions:

• Gender-specific prostheses yield functional results equivalent to conventional prostheses 5 years after TKA.
• The choice between gender-specific and conventional prostheses may not significantly impact long-term functional outcomes.
• Further research may explore other potential benefits or specific patient populations for gender-specific implants.
