This study evaluated porous-coated P.C.A. total knee prostheses, finding excellent results in 87% of patients. However, complications like pulmonary embolism and deep infection were noted.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science

Background:

  • Total knee arthroplasty is a common procedure for knee osteoarthritis.
  • Porous-coated prostheses aim to improve bone integration and long-term fixation.

Purpose of the Study:

  • To evaluate the clinical and radiographic outcomes of porous-coated P.C.A. total knee prostheses.
  • To assess complications associated with this type of prosthesis.

Main Methods:

  • Implantation of 36 porous-coated P.C.A. total knee prostheses in 34 patients between 1983 and 1986.
  • Clinical evaluation using the Hungerford system after an average 18-month follow-up.
  • Radiographic assessment of prosthetic positioning, radiolucent lines, and bone resorption.

Main Results:

Related Experiment Videos

  • Excellent results in 87% and fair in 13% of 23 evaluated patients.
  • Complications included two fatal pulmonary embolisms and one deep infection.
  • Radiographic evaluation showed excellent positioning in 70%, radiolucent lines in 21%, and bone resorption in 43% of cases.

Conclusions:

  • Porous-coated P.C.A. total knee prostheses can achieve good clinical outcomes.
  • Potential complications include pulmonary embolism and deep infection.
  • Radiographic findings suggest areas for improvement in prosthesis positioning and bone integration.
