Older adult patients with hip fractures are 3–4 times more likely to die within one-year after surgery than general population. The study aimed to identify independent predictive factors associated with one-year mortality after hip fracture surgery. A prospective prognostic cohort study was performed. All patients aged ≥65 years, consecutively admitted in three Italian hospitals with a diagnosis of fragility hip fracture were included. Patients with periprosthetic or pathological fractures were excluded. Multivariate analysis was used to determine variables that significantly increased the risk of one-year mortality and Receiver operating characteristic (ROC) curve analysis to assess their predictive capacity on the outcome.1083 patients fulfilled the inclusion criteria and the one-year follow-up was reached in 728 patients. The 16.6% of patients died within one-year after surgery. At the multivariate analysis, advancing age (OR = 1.094, 95% CI = 1.057–1.132), higher baseline Charlson Index (OR = 1.257, 95% CI = 1.114–1.418) and Activities of Daily Living scores (OR = 1.259, 95% CI = 1.143–1.388), presence of hospital-acquired pressure ulcers (PUs) (OR = 1.579, 95% CI = 1.002–2.489) and lack recovery of ambulation (OR = 1.736, 95% CI = 1.115–2.703), were found to be independent predictive factors of one-year mortality after surgery. The area under the ROC curve of the model was 0.780 (CI95% 0.737–0.824) for one-year mortality in elderly hip fractures patients. Early ambulation and careful long-term follow-up, with attention to frailty in elderly people, should be promoted.

The objective of this study is to describe the rehabilitative pathway of patients undergoing endoprosthetic knee replacement surgery, build reference values of the functional results achieved, and identify possible prognostic factors. Prospective observational study. All patients undergoing resection and knee replacement surgery using a modular prosthesis following bone tumor resection were consecutively recruited over the last 2 years. The patients were followed for a period of 1 year, the result values were collected at 3, 6 and 12 months. In total, 30 patients were enrolled. The median age was 19 years with 33% of patients being female. Median values recorded for knee flexion, quadriceps strength, Toronto Extremity Salvage Score, Time Up and Go and Six Minutes Walking Test showed an improvement of 16, 25, 18, 48 and 38% from 3 to 12 months, respectively. The level and width of the resection were correlated with the mobility of the knee and the strength of the quadriceps. Patients undergoing knee replacement for bone tumors were able to achieve satisfactory functional outcomes from the first postoperative year. A specific assessment of outcomes can be conducted to facilitate the management of patient expectations. A very wide resection and interventions of the proximal tibia are risk factors for a poorer functional outcome.
Background: Considerable attention has been paid to the role of kinesiophobia with respect to knee prosthesis but it has not yet been studied as a prognostic factor of short-term functional performance following total hip replacement. The main purpose of the present study is to examine the possible predictors of early functional performance of patients undergoing total primary hip arthroplasty, including demographics as age, sex and body mass index, preoperative functional ability, type of anaesthesia, level of haemoglobin, pain and level of kinesiophobia before surgery. Secondly, we want to describe the main characteristics of the population with the highest levels of kinesiophobia. Methods: A prospective, prognostic cohort study was carried out. Patients undergoing primary hip replacement were recruited consecutively. The main outcome is the early functional performance achieved by patients after surgery and measured using the Iowa Level of Assistance (ILOA) scale on the fifth postoperative day. Preoperative kinesiophobia was measured by the Tampa Scale and the preoperative functional ability by the Western Ontario and McMaster Osteoarthritis Index (WOMAC). The multivariate analysis was performed by the General Linear Model. The analysis of the population with high levels of kinesiophobia was conducted by identifying a cut-off of 40 compared to the Tampa Scale. Results: Statistical analysis was performed on 269 patients. The average ILOA score recorded was 19.5 (DS 8.3). The levels of kinesiophobia, showed an average score of 35.1 (7.8) and it was not associated with early functional performance. The independent predictive factors include age, sex and body mass index. Kinesiophobia high levels were recorded in 30% of the population and this population had a higher level of pre-operative WOMAC score. Conclusions: Early functional performance after hip replacement surgery was not correlated with the level of kinesiophobia. Three significant factors that describe a population most at risk of not achieving optimal functional performance are increased age, being female and increase in body mass index. In the preoperative phase, high levels of kinesiophobia were associated with more impaired preoperative functional ability. Trial registration: Current Controlled Trials NCT02786121, May 2016.
