Press Release Summary: Polyethylene Acetabular Component insertion during total hip
arthroplasty, Dr. Ranawat has observed a mean linear wear of 0.075 mm per year with
compression molded cups.

Press Release Body: Dr. Chitranjan Ranawat and his team members designed
polyethylene acetabular component used in total hip arthroplasties with cemented
expansion acetabular component for advanced osteonecrosis of the femoral head.

After the study on orthopaedic patients who have gone through total hip arthroplasty
with polyethylene acetabular components insertion having less wear of 0.075 mm per
year, says Dr. Ranawat. Study reports that the use of a cemented stem and cemented
cup combination has more advantage than other insertions. The study group consisted
of 80 males and 100 females, mean age 73.5 years (range: 62-85 years), and mean
weight 155 lb (range: 104-230 lb). The mean follow-up was 8 years. Only 1 stem was
revised in this series and 1 hip experienced dislocation. A patient questionnaire
revealed significantly reduced pain, less use of a cane, and a lower incidence of
limp vs uncemented total hip outcomes.

Dr. Ranawat is fascinated of new highly cross-linked polyethylenes, but he needed to
perform independent wear testing. His results demonstrated that highly cross-linked
polyethylene can reduce acetabular wear to about 0.025 mm per year. Contact Dr.
Ranawat to know more on polyethylene acetabular component insertion during total hip
arthroplasty.
