Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science

Background:

  • Total hip arthroplasty (THA) is a common procedure for hip joint diseases.
  • Cementless porous-coated implants are increasingly used to promote bone ingrowth and long-term fixation.

Purpose of the Study:

  • To evaluate the clinical and radiographic outcomes of cementless porous-coated total hip arthroplasties.
  • To assess the long-term efficacy and potential complications of this implant type.

Main Methods:

  • Analysis of 81 cementless porous-coated total hip arthroplasties in 74 patients.
  • Serial assessment using Harris hip rating scores and radiographic evaluations (AP and lateral) at multiple postoperative intervals (3 months, 6 months, 1 year, 2 years, and 4 years).

Main Results:

  • High average postoperative Harris hip scores at 1 year (91 points) and 2 years (93 points).
  • Overall satisfactory clinical results observed at 2 and 4 years postoperatively.
  • Incidence of thigh pain: 19.8% at 2 years and 21.3% at 4 years.
  • Incidence of moderate to severe limp: 13.6% at 2 years and 14.9% at 4 years.

Conclusions:

  • Cementless porous-coated THA demonstrates good clinical success and satisfactory patient outcomes in the medium term.
  • Persistent thigh pain and limp are potential complications that require monitoring in patients undergoing this procedure.
