Total hip replacement comparison between the McKee-Farrar and Charnley prostheses in a 5-year follow-up study. 1986

K Djerf, and O Wahlström

In a prospective study, 177 patients who underwent total hip replacement by the McKee-Farrar or Charnley techniques were followed up for 5 years with yearly clinical examinations, walking tests, and X-rays. The findings concerning pain, walking ability, and complications were satisfactory and similar to the inventors' own 5-year results. Comparison between the two techniques disclosed no major differences. Over 90% of the patients were free from pain; the infection rate was 3.4% and the loosening rate 6%. A walking test showed marked increase in speed over the first few years and a slight decrease after the third year. Our findings do not support the hypothesis that the metal-on-metal prosthesis is clinically inferior to the metal-on-polyethylene prosthesis.

D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.
