الوصف: BackgroundNumerous papers have been published examining risk factors for revision of primary total hip arthroplasty (THA), but there have been no comprehensive systematic literature reviews that summarize the most recent findings across a broad range of potential predictors.MethodsWe performed a PubMed search for papers published between January, 2000 and November, 2010 that provided data on risk factors for revision of primary THA. We collected data on revision for any reason, as well as on revision for aseptic loosening, infection, or dislocation. For each risk factor that was examined in at least three papers, we summarize the number and direction of statistically significant associations reported.ResultsEighty-six papers were included in our review. Factors found to be associated with revision included younger age, greater comorbidity, a diagnosis of avascular necrosis (AVN) as compared to osteoarthritis (OA), low surgeon volume, and larger femoral head size. Male sex was associated with revision due to aseptic loosening and infection. Longer operating time was associated with revision due to infection. Smaller femoral head size was associated with revision due to dislocation.ConclusionsThis systematic review of literature published between 2000 and 2010 identified a range of demographic, clinical, surgical, implant, and provider variables associated with the risk of revision following primary THA. These findings can inform discussions between surgeons and patients relating to the risks and benefits of undergoing total hip arthroplasty.

الوصف: Revision hip arthroplasty is associated with less favorable short and longterm results than primary total hip arthroplasty (THA). We compared quality of life and satisfaction 5 years after the 2 interventions, to determine the influence of patient characteristics on poorer outcomes after revision, and to analyze if their influence differed for primary and for revision arthroplasty.

مستخلص: Background: There is growing concern about the use of opioids prior to total knee arthroplasty (TKA), and research has suggested that preoperative opioid use may lead to worse pain outcomes following surgery. We evaluated the pain relief achieved by TKA in patients who had and those who had not used opioids use before the procedure.Methods: We augmented data from a prospective cohort study of TKA outcomes with opioid-use data abstracted from medical records. We collected patient-reported outcomes and demographic data before and 6 months after TKA. We used the Pain Catastrophizing Scale and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) to quantify the pain experiences of patients treated with TKA who had had a baseline score of ≥20 on the WOMAC pain scale (a 0 to 100-point scale, with 100 being the worst score), who provided follow-up data, and who had not had another surgical procedure within the 2 years prior to TKA. We built a propensity score for preoperative opioid use based on the Pain Catastrophizing Scale score, comorbidities, and baseline pain. We used a general linear model, adjusting for the propensity score and baseline pain, to compare the change in the WOMAC pain score 6 months after TKA between persons who had and those who had not used opioids before TKA.Results: The cohort included 156 patients with a mean age of 65.7 years (standard deviation [SD] = 8.2 years) and a mean body mass index (BMI) of 31.1 kg/m (SD = 6.1 kg/m); 62.2% were female. Preoperatively, 36 patients (23%) had had at least 1 opioid prescription. The mean baseline WOMAC pain score was 43.0 points (SD = 12.8) for the group that had not used opioids before TKA and 46.9 points (SD = 15.7) for those who had used opioids (p = 0.12). The mean preoperative Pain Catastrophizing Scale score was greater among opioid users (15.5 compared with 10.7 points among non-users, p = 0.006). Adjusted analyses showed that the opioid group had a mean 6-month reduction in the WOMAC pain score of 27.0 points (95% confidence interval [CI] = 22.7 to 31.3) compared with 33.6 points (95% CI = 31.4 to 35.9) in the non-opioid group (p = 0.008).Conclusions: Patients who used opioids prior to TKA obtained less pain relief from the operation. Clinicians should consider limiting pre-TKA opioid prescriptions to optimize the benefits of TKA.Level Of Evidence: Therapeutic Level III.

مستخلص: Background: There is little research on the long-term outcomes of open carpal tunnel release. The purpose of this retrospective study was to determine the functional and symptomatic outcomes of patients at a minimum of ten years postoperatively. Methods: Two hundred and eleven patients underwent open carpal tunnel release from 1996 to 2000 performed by the same hand fellowship-trained surgeon. Follow-up with validated self-administered questionnaire instruments was conducted an average of thirteen years after surgery. The principal outcomes included the Levine-Katz symptom and function scores, ranging from 1 point (best) to 5 points (worst), and satisfaction with the results of surgery. The patients self-reported current comorbidities. Results: After a mean follow-up of thirteen years (range, eleven to seventeen years), 92% (194) of 211 patients were located. They included 140 who were still living and fifty-four who had died. Seventy-two percent (113) of the 157 located, surviving patients responded to the questionnaire. The mean Levine-Katz symptom score (and standard deviation) was 1.3 ± 0.5 points, and 13% of patients had a poor symptom score (≥2 points). The mean Levine-Katz function score was 1.6 ± 0.8 points, and 26% had a poor function score (≥2 points). The most common symptom-related complaint was weakness in the hand, followed by diurnal pain, numbness, and tingling. The least common symptoms were nocturnal pain and tenderness at the incision. Eighty-eight percent of the patients were either completely satisfied or very satisfied with the surgery. Seventyfour percent reported their symptoms to be completely resolved. Thirty-three percent of men were classified as having poor function compared with 23% of women. Two (1.8%) of 113 patients underwent repeat surgery. Conclusions: At an average of thirteen years after open carpal tunnel release, the majority of patients are satisfied and free of symptoms of carpal tunnel syndrome. [ABSTRACT FROM AUTHOR]

مستخلص: Objectives To identify older adults with comorbidities or poor functional status at high risk of postoperative venous thromboembolism ( VTE). Design Retrospective cohort study. Setting Veterans Affairs Medical Center ( VAMC). Participants Older adults who underwent total hip and knee replacement ( THR and TKR) from 2002 to 2009. Measurements Using multivariate logistic regression, the independent effect of cardiopulmonary comorbidities and diabetes on VTE was analyzed. Functional status expressed in a summary physical component score ( PCS) was also analyzed in a subset of individuals in whom information on it was available. Results There were 23,326 THR and TKR surgeries performed at the VAMC during the study period. Individuals with chronic obstructive pulmonary disease ( COPD) had a 25% greater risk of VTE (odds ratio ( OR) = 1.25, 95% confidence interval ( CI) = 1.06-1.48), whereas those with coronary artery disease, congestive heart failure, and cerebrovascular disease did not have a greater risk of VTE. Individuals with diabetes mellitus had a lower risk of VTE ( OR = 0.77, 95% CI = 0.64-0.92). Individuals with low PCS, which were available for 3,169 patients, had a 62% greater risk, although the effect did not reach statistical significance (lowest vs highest quartile OR = 1.62, 95% CI = 0.93-2.80). Conclusion Individuals with COPD had slightly greater risk of VTE, whereas low functional status had a larger effect that did not reach statistical significance. The constraints of administrative data analysis and sample size available for PCS limit conclusions about the role of these comorbidities and functional status. [ABSTRACT FROM AUTHOR]

مستخلص: Abstract: Objectives: To investigate the association between multimorbidity—a construct comprising several health domains (medical comorbidity, musculoskeletal, physical and social functional status, mental health, and geriatric problems)—and overall self-rated health (SRH), an important chronic disease health outcome. We investigate whether medical comorbidity effects are mediated through other health domains and whether these domains have independent effects on SRH. Study Design and Setting: Medicare recipients (n =958) completed a questionnaire 3 years post primary total hip replacement surgery. Self-reported sociodemographic characteristics, SRH, and health domain statuses were ascertained. Probit regressions and path analyses were used to evaluate the independent effects of the health domains on SRH and the interrelationships between domains and to quantify direct and mediated effects. Results: All domains were independently associated with SRH. Medical comorbidity explained 11.7% of the variance in SRH, and all other health domains explained 27.3%. The impact of medical comorbidity was largely direct (only 21.5% mediated through other domains). Medical comorbidity minimally explained the variance in other domain scores. Conclusion: SRH has multiple determinants. This finding suggests that an exclusive focus on any one domain in health research may limit the researchers'' ability to understand health outcomes for which SRH is predictive.
