Determinants of 6—12 Month Postoperative Functional Status and Pain After Elective Total Hip Replacement

Abstract

The results indicate that 93% of patients studied reported at least one significant co-morbidity. The mean pre-operative pain score was 7.5 on a 0-10 scale and average change in pain was 4.8. Regression analyses indicate that increased body mass index is associated with lower post-operative functional status and increased post-operative pain. The amount of pain relief the patient was able to obtain pre-operatively using non-surgical interventions was associated with a better outcome.

Early prosthetic hip joint infection treated with debridement, prosthesis retention and biofilm‐active antibiotics: functional outcomes, quality of life and complications

“…Similar factors have been demonstrated in previous studies to predict worse functional and QOL outcomes. 19,20 Medical complications occurred more commonly in patients with PJI compared with controls in this study, but these were mainly drug reactions to intravenous or oral antibiotics to which controls were obviously not exposed. Rates of other medical or surgical complications occurred at similar rates in cases and controls despite the extra surgical and medical treatment required for PJI cases, suggesting that, aside from the risk of drug reaction, this treatment approach is well tolerated.…”

“…Baseline demographic information of cases and controls is shown in Table 1. For cases, the median duration from joint insertion until first debridement (joint age) was 14 days (interquartile range (IQR) [12][13][14][15][16][17][18][19][20]. The median duration of symptoms until debridement was 4 days (IQR 3-9).…”

Preoperative predictors of locomotor ability two months after total knee arthroplasty for severe osteoarthritis

“…However, to our knowledge, it is the first time that a longitudinal association between a quantitative measure of locomotor ability and these personal characteristics is observed in persons with TKA. This may be explained by the fact that these personal characteristics are associated with other potential predictors such as locomotor measures (Table 4), strength (17,147), and pain (20,26). Thus, when these latter predictors are retained in the regression analyses, personal predictors do not have an independent contribution to the prediction.…”

“…As in our study, pain, knee strength, and flexion were retained in regression models to predict locomotor ability (64,139,143) or self-perceived functional ability (25,26,64,144,146,153,161) in different populations as were gait power peaks in persons with stroke (97).…”

“…Instead, previous studies have predicted self-reported functional ability after TKA and total hip arthroplasty using questionnaires (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28). Among these studies, only 4 used a questionnaire that evaluates specifically the physical function of the lower limbs (15,19,20,27).…”
