Evaluation of functional outcome between cemented and uncemented total hip replacement

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Clinical Outcomes Research

Background:

• Total hip arthroplasty (THR) effectively improves patient mobility and quality of life.
• The comparative functional outcomes between cemented and uncemented THR techniques are not fully established.
• Debate continues regarding the optimal fixation method for hip replacement surgery.

Purpose of the Study:

• To prospectively compare the clinical and radiological outcomes of cemented versus uncemented total hip arthroplasty.
• To evaluate early and long-term functional recovery in patients undergoing THR.
• To determine if one fixation technique offers superior results over the other.

Main Methods:

• Prospective randomized study involving 50 patients undergoing THR.
• Patients were divided into two equal groups: cemented and uncemented implants.
• Clinical and radiological assessments were conducted preoperatively and up to 4 years postoperatively.

Main Results:

• Cemented THR showed significantly better early outcomes, including pain relief and Harris Hip Scores at 6 weeks and 3 months.
• Functional outcomes converged between cemented and uncemented THR groups by 6 months post-surgery.
• Both techniques resulted in good-to-excellent outcomes with minimal complications at the 4-year follow-up.

Conclusions:

• Cemented THR implants facilitate a faster initial recovery period for patients.
• Long-term functional advantages of uncemented THR implants require additional investigation.
• Individualized patient factors may influence the optimal choice between cemented and uncemented hip implants.
