Cemented total hip arthroplasty with contemporary techniques. A five-year minimum follow-up study

Area of Science:

• Orthopedic Surgery
• Biomaterials Science

Background:

• Cemented total hip arthroplasty (THA) is a common procedure for hip joint restoration.
• Evaluating long-term outcomes of cemented THA is crucial for surgical technique and implant design refinement.

Purpose of the Study:

• To assess the clinical and roentgenographic outcomes of cemented total hip arthroplasties (THA) using specific contemporary techniques.
• To establish a benchmark for cemented THA performance against which alternative systems can be compared.

Main Methods:

• Retrospective review of 251 consecutive cemented THAs performed between 1978-1980.
• Minimum five-year follow-up (range: 5-7 years) including clinical Harris hip scores and roentgenographic assessment.
• Standardized surgical technique involving Harris Design II femoral stem, intramedullary plug, cement gun, and pulsatile lavage.

Main Results:

• 98% of patients achieved excellent clinical results at final follow-up.
• Significant improvement in average Harris hip score from 47 preoperatively to 97 postoperatively.
• Low rates of component loosening (3 definite, 1 probable, 2 possible loose femoral stems; 1 loose acetabular component) with no revisions performed.

Conclusions:

• Contemporary cemented THA techniques, including the Harris Design II stem, yield excellent long-term clinical and radiographic outcomes.
• The observed low revision rate and high patient satisfaction underscore the efficacy of this cemented THA approach.
• This series provides a valuable standard for evaluating novel cemented total hip arthroplasty systems.
