Older patients with multiple medical co-morbidities
are increasingly being offered and undergoing total joint arthroplasty
(TJA). These patients are more likely to require intensive care
support, following surgery. We prospectively evaluated the need
for intensive care admission and intervention in a consecutive series
of 738 patients undergoing elective hip and knee arthroplasty procedures.
The mean age was 60.6 years (18 to 91; 440 women, 298 men. Risk
factors, correlating with the need for critical care intervention,
according to published guidelines, were analysed to identify high-risk
patients who would benefit from post-operative critical care monitoring.
A total of 50 patients (6.7%) in our series required critical care
level interventions during their hospital stay. Six independent
multivariate clinical predictors were identified (p <
0.001)
including a history of congestive heart failure (odds ratio (OR)
24.26, 95% confidence interval (CI) 9.51 to 61.91), estimated blood
loss >
1000 mL (OR 17.36, 95% CI 5.36 to 56.19), chronic obstructive
pulmonary disease (13.90, 95% CI 4.78 to 40.36), intra-operative
use of vasopressors (OR 8.10, 95% CI 3.23 to 20.27), revision hip
arthroplasty (OR 2.71, 95% CI 1.04 to 7.04) and body mass index
>
35 kg/m2 (OR 2.70, 95% CI 123 to 5.94). The model was
then validated against an independent, previously published data
set of 1594 consecutive patients. The use of this risk stratification
model can be helpful in predicting which high-risk patients would
benefit from a higher level of monitoring and care after elective
TJA and aid hospitals in allocating precious critical care resources. Cite this article:

Between 1971 and 1991 we performed Charnley low-friction arthroplasty (LFA) on 116 patients (186 hips) with juvenile chronic arthritis (JCA). We have now carried out a survival study, taking endpoints as revision, death or the end of the year 1993. Overall survival was 91.9% at ten years and 83.0% at 15 years. That of the femoral component was 95.6% at ten years and 91.9% at 15 years and of the acetabulum 95.0% and 87.8%, respectively. Only the use of steroids significantly impaired the survival. We therefore recommend the use of Charnley LFA for young patients with JCA requiring

From a series of 135 patients (146 prostheses) who had had primary hip replacement in 1975 and 1976 we reported the outcome at ten years in 83 surviving patients in 1988 and that at 15 years in 44 surviving patients in 1994. Now, 22 years after the operation, we have reviewed the 21 patients who are still alive. Nineteen (20 hips) of these 21 patients (22 hips) with a mean age of 85.7 years still had their original prosthesis. Most patients were satisfied with the result, although the level of activity in many was reduced because of increasing age and other medical problems. The stem was stable in all 20 hips. Only one cup was definitely loose. Wear was observed in 40% of the cups but this was not a clinical problem. At the 22-year follow-up the cumulative survival rate of the prosthesis was 85%, of the stem 91% and of the cup 88%. Since 1975, 11 (7.5%) of the original 146 prostheses have been revised.
We followed 138 patients (145 hips) who had had uncemented total hip arthroplasty using the Taperloc femoral component for a mean of ten years (8 to 12.5). No patient was lost to follow-up; 31 (31 hips) died before the minimum time of eight years for inclusion in the study, and 30 of these still had their femoral component in place. One well-fixed prosthesis had been exchanged at the time of acetabular revision. Of the remaining 114 hips, one femoral component required revision for aseptic loosening and one for sepsis. Three other well-fixed femoral components were removed during acetabular revision. Complete clinical and radiological follow-up was obtained in the 109 hips which had not had revision. Clinically, 94 (87%) were rated good or excellent, eight (7%) fair and seven (6%) poor. The average Harris hip score increased from 48 before operation to 88 at the time of the last follow-up. Radiologically, 103 hips (94%) had fixation by bone ingrowth, three (3%) showed stable fibrous ingrowth and three (3%) were unstable. Osteolysis of the femoral cortex was seen in seven hips (6%), with major lysis in only one. At a mean follow-up of ten years, the results of the Taperloc femoral component are comparable with those of modern techniques of cementing in primary total hip arthroplasty.
We report 16 cases of erythematous eruption on the skin within the flaps of the surgical incision after primary total hip replacement over an eight-year period. The symptoms began within nine months of operation in 13 hips, and two to three years after in three. Four patients had recurrent episodes. All were treated with antibiotics (15 intravenous, one oral) with complete resolution of the eruption within one to six days. The mean follow-up after the last episode of cellulitis was 27 months (14 to 76). There were no cases of periprosthetic sepsis or other sequelae.
