TL;DR: In this paper, the average volumetric wear rate per million cycles with a 70 kg patient weight was 30 mm 3, which can be considered a target wear rate for standard polyethylene in hip simulator studies.

TL;DR: Individual differences in the activity of the patient can be a substantial source of variability in rates of polyethylene wear in vivo, and the pedometer is an inexpensive investigational tool with many potential applications, including standardizing wear measurements of joint replacements on the basis of gait cycles rather than time.

TL;DR: Before the advent of total joint replacement, patients who had end-stage arthritis of the lower extremities had unremitting pain and a greatly decreased functional capacity and today, the outcomes of primary total hip and knee replacement are predictable and usually excellent.

TL;DR: Serum and urine metal concentrations may be useful markers for the tribologic performance of metal on metal bearings in total hip arthroplasty.

TL;DR: Postoperative neuropathy in the ipsilateral lower extremity was identified in 3126 consecutive total hip replacements and the prognosis for neurological recovery was related to the degree to which the nerve was damaged.
