Outcome of the contralateral hip following total hip arthroplasty for osteoarthritis.

One thousand one hundred and sixteen patients who underwent unilateral total hip arthroplasty osteoarthritis between 1970 and 1980 were examined for development, progression, and total hip arthroplasty in the contralateral joint. At the time of the original surgery, 452 patients were diagnosed with bilateral osteoarthritis and 664 had a normal contralateral hip. The probability of osteoarthritis progressing in the contralateral joint is 78.

The influence of age and gender on the outcome of total knee arthroplasty.

1. The influence of age and gender on the outcome of total knee arthroplasty was examined in 762 knees (490 patients). 2.

The effect of heterotopic bone formation on prosthetic loosening after total hip replacement.

Seven hundred thirty-two total hip replacements performed from 1970 to 1980 were evaluated for the degree of heterotopic bone formation postoperatively and its effect on long-term mechanical loosening. There were 231 Charnley total hip replacements, of which 152 had no heterotopic bone formation, 58 had Grade 1 formation, and 21 had Grade 2 or 3 formation. Among the 123 Mueller total hip replacements, 98 had no heterotopic bone formation, 19 had Grade 1 formation, and 6 had Grade 2 or 3 formation.

Developing an effective adult nutrition screening tool for a community hospital.

Objective: To develop a sensitive and specific nutrition screening tool that conforms to the requirements of the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) and is effective in any given hospital population.

Design: A two-step prospective evaluation was performed in two unrelated community hospitals to determine the effectiveness of a current nutrition screening tool, and to develop a new, more sensitive tool that permits efficient use of available personnel.

Statistical Analyses: Standard calculations for sensitivity, specificity, positive predictive value, and negative predictive value were used to compare the results of various screening methods with those of full nutrition assessments.

Revision total knee arthroplasty. A survival analysis.

The results of revision total knee arthroplasty (TKA) have been documented reasonably well in the literature. It is notable, however, that none of these reports have used the technique known as survival analysis to compare virgin and revision arthroplasties. This technique has an advantage over conventional analyses because it does not exclude patient data for inadequate follow-up study or patient death.
