Abstract
Aims The aim of this study was to investigate the association between additional rehabilitation at the weekend, and in-hospital mortality and complications in patients with hip fracture who underwent surgery. Methods A retrospective cohort study was conducted in Japan using a nationwide multicentre database from April 2010 to March 2018, including 572,181 patients who had received hip fracture surgery. Propensity score matching was performed to compare patients who received additional weekend rehabilitation at the weekend in addition to rehabilitation on weekdays after the surgery (plus-weekends group), as well as those who did not receive additional rehabilitation at the weekend but did receive weekday rehabilitation (weekdays-only group). After the propensity score matching of 259,168 cases, in-hospital mortality as the primary outcome and systemic and surgical complications as the secondary outcomes were compared between the two groups. Results The plus-weekends group was significantly associated with lower in-hospital mortality rates compared with the weekdays-only group (hazard ratio 0.86; 95% confidence interval 0.8 to 0.92; p < 0.001). Systemic complications such as acute coronary syndrome, heart failure, renal failure, and sepsis were significantly lower in the plus-weekends group, whereas urinary tract infection (UTI) and surgical complications such as surgical site infection and haematoma were significantly higher in the plus-weekends group. Conclusion Additional weekend rehabilitation was significantly associated with lower in-hospital mortality, as well as acute coronary syndrome, heart failure, renal failure, and sepsis, but was also significantly associated with a higher risk of UTI and surgical complications. This result can facilitate the effective use of the limited rehabilitation resources at the weekend and improve the clinical awareness of specific complications. To establish more robust causal associations between additional rehabilitation over the weekend and clinical outcomes, further prospective studies or randomized controlled trials with larger sample sizes are warranted.

Abstract
UNLABELLED Additional physiotherapy in the first postoperative week was associated with fewer days to discharge after hip fracture surgery. A 7-day physiotherapy service in the first postoperative week should be considered as a new key performance indicator in evaluating the quality of care for patients admitted with a hip fracture. INTRODUCTION To examine the association between physiotherapy in the first week after hip fracture surgery and discharge from acute hospital. METHODS We linked data from the UK Physiotherapy Hip Fracture Sprint Audit to hospital records for 5395 patients with hip fracture in May and June 2017. We estimated the association between the number of days patients received physiotherapy in the first postoperative week; its overall duration (< 2 h, ≥ 2 h; 30-min increment) and type (mobilisation alone, mobilisation and exercise) and the cumulative probability of discharge from acute hospital over 30 days, using proportional odds regression adjusted for confounders and the competing risk of death. RESULTS The crude and adjusted odds ratios of discharge were 1.24 (95% CI 1.19-1.30) and 1.26 (95% CI 1.19-1.33) for an additional day of physiotherapy, 1.34 (95% CI 1.18-1.52) and 1.33 (95% CI 1.12-1.57) for ≥ 2 versus < 2 h physiotherapy, and 1.11 (95% CI 1.08-1.15) and 1.10 (95% CI 1.05-1.15) for an additional 30-min of physiotherapy. Physiotherapy type was not associated with discharge. CONCLUSION We report an association between physiotherapy and discharge after hip fracture. An average UK hospital admitting 375 patients annually may save 456 bed-days if current provision increased so all patients with hip fracture received physiotherapy on 6-7 days in the first postoperative week. A 7-day physiotherapy service totalling at least 2 h in the first postoperative week may be considered a key performance indicator of acute care quality after hip fracture.

Abstract
Abstract
Objective
To explore physiotherapists’ perceptions of mechanisms to explain observed variation in early postoperative practice after hip fracture surgery demonstrated in a national audit.
Methods
A qualitative semi-structured interview study of 21 physiotherapists working on orthopaedic wards at 7 hospitals with different durations of physiotherapy during a recent audit. Thematic analysis of interviews drawing on Normalisation Process Theory to aid interpretation of findings.
Results
Four themes were identified: achieving protocolised and personalised care; patient and carer engagement; multidisciplinary team engagement across the care continuum; and strategies for service improvement. Most expressed variation from protocol was legitimate when driven by what is deemed clinically appropriate for a given patient. This tailored approach was deemed essential to optimise patient and carer engagement. Participants reported inconsistent degrees of engagement from the multidisciplinary team attributing this to competing workload priorities, interpreting ‘postoperative physiotherapy’ as a single professional activity rather than a care delivery approach, plus lack of integration between hospital and community care. All participants recognised changes needed at both structural and process levels to improve their services.
Conclusion
Physiotherapists highlighted an inherent conflict between their intention to deliver protocolised care while allowing for an individual patient-tailored approach. This conflict has implications for how audit results should be interpreted, how future clinical guidelines are written, and how physiotherapists are trained. Physiotherapists also described additional factors explaining variation in practice which may be addressed through increased engagement of the multidisciplinary team and resources for additional staffing and advanced clinical roles.

Abstract
BACKGROUND The loss of pre-fracture basic mobility status is associated with increased mortality and any readmission after hip fracture. However, it is less known if the loss of pre-fracture mobility has impact on acquiring a post-discharge infection. PURPOSE To examine if the loss of pre-fracture basic mobility status at hospital discharge was associated with hospital-treated or community-treated infections within 30-days of hospital discharge after hip fracture. METHODS Using the nationwide Danish Multidisciplinary Hip Fracture Registry from January 2014 through November 2017, we included 23,309 patients undergoing surgery for a first-time hip fracture. The Cumulated Ambulation Score (CAS, 0-6 points) was recorded using questionnaire at admission (pre-fracture CAS) and objectively assessed at discharge. The loss of any CAS-points at discharge compared with pre-fracture CAS was calculated and dichotomized (yes/no). Using Cox regression analyses, we estimated the hazard ratio (HR) with 95% confidence interval (CI) of any hospital-treated infection, hospital-treated pneumonia or community-treated infection adjusted for sex, age, body mass index, Charlson Comorbidity Index, residential status, type of fracture, and length of hospital stay (LOS). RESULTS Total of 12,046 (62%) patients lost their pre-fracture CAS status at discharge. Among patients who had lost their pre-fracture CAS, 6.0% developed a hospital-treated infection compared to 4% of those who did not lose their pre-fracture CAS. Correspondingly, 9.2% versus 6.2% developed a community-treated infection. The risk of 30-day post-discharge infection increased with increasing loss of any CAS points. The adjusted HRs for patients who had lost their pre-fracture CAS status, compared to patients who did not, was 1.34 (CI: 1.16-1.54) for hospital-treated infection, 1.35 (CI: 1.09 - 1.67) for pneumonia and 1.36 (CI: 1.21-1.52) for community-treated infection. CONCLUSION In this large national cohort study, we found that loss of pre-fracture basic mobility status upon hospital discharge was strongly associated with 30-day post-discharge risk of developing infection. These findings suggest a clinical importance of carefully focusing on regaining the pre-fracture basic mobility before discharging the patient.

Abstract
OBJECTIVE To examine the influence and risk of falls of individual factors on timed up and go test (TUG) times using standardized instructions in patients with hip fracture upon discharge from an acute orthopaedic hip fracture unit. METHODS Following instructions, the TUG was performed three times with a rollator (standardized aid), as fast as safely possible. Up to a 1-min rest was given after the first and second TUG trial. Multivariable linear regression analysis was used to investigate the factors influencing TUG-times and corresponding logistic analysis was used to investigate factors indicating risk of falls, using a cut-off of 24 s for TUG. RESULTS A total of 181 patients (122 women), 60 years or older, with a mean (SD) age of 78.1 (9.1) years were studied. The fastest of three TUG trials performed within a mean of 10.0 (5.2) post-surgery days and used in analyses reached a mean of 25.6 (11.0) s. Multivariable regression analysis showed that greater age (B = 0.24; 2.4s more per decade older), a low pre-fracture function level (New Mobility Score <7 points, B = 6.4s more than high level), having a trochanteric fracture (B = 6.2 s, vs. cervical), and the post-surgery day of testing (B = 0.42, 4.2s per 10 days later) were independently associated with using more time for performing the TUG. Correspondingly, the same four factors indicated an increased risk of falls in the logistic analysis. The linear model explained 28% of the variance on TUG, while the accuracy of the logistic model to predict patients having TUG≥24 s was 69%. CONCLUSION The age, pre-fracture function, fracture type and post-surgery day of TUG testing were identified as strong factors influencing TUG performances and TUG-times indicating risk of falls in patients with hip fracture. We suggest that these factors be considered when interpreting TUG test results and in further rehabilitation and fall prevention efforts.

Abstract
Background and Purpose: Originally, the Timed Up & Go (TUG) test was described as including a practice trial before a timed trial, but recent studies in individuals with hip fracture have reported that performance improved with a third trial and that high intertester reliability was achieved when the fastest of 3 timed trials was used. Thus, the fastest of 3 TUG trials is recommended when testing individuals with hip fracture. To our knowledge, no study has examined the number of trials needed to achieve performance stability on the TUG test (defined as no further improvement on subsequent trials) when performed by older individuals without hip fracture. The aim of the study, therefore, was to examine whether a third TUG trial is faster than either of 2 TUG trials conducted according to standardized TUG instructions and whether the fastest of 3 trials is the most appropriate measure to apply in hospitalized and community-dwelling older individuals. Methods: Eighty-two participants (50 from a geriatric hospital unit and 32 from an outpatient geriatric center; 52 women, 30 men) with a mean (SD) age of 83.6 (7.9) years were included in this cross-sectional study. All participants (except one from the hospital unit) performed 3 TUG trials, as fast as safely possible on the same day, and separated by up to 1-minute pauses. A rollator (4-wheeled rolling walker) was used as a standardized walking aid in the geriatric hospital unit, whereas participants used their normal walking aid (if any) in the outpatient geriatric center. Results and Discussion: The fastest trial was trial 3 for 47 (57%), trial 2 for 25 (31%), and trial 1 for 10 (12%). Repeated-measures analyses of variance with Bonferroni corrections showed that TUG times improved from trial 1 to trial 3 (P < .04). In addition, the fastest of the 3 timed trials was significantly (P < .001) faster than the other 2 trials. Conclusion: We suggest that the fastest of the 3 TUG trials is recorded instead of the second trial in both hospitalized and community-dwelling older individuals.

Abstract
Background and purpose - An enhanced treatment program may decrease 30-day mortality below 20% after lower extremity amputations (LEA). The potential and limitations for further reduction are unknown. We analyzed postoperative causes of 30-day mortality, and assessed failure to rescue (FTR) rate in LEA patients who followed an enhanced treatment program. Patients and methods - Medical charts of 195 primary LEA procedures were reviewed independently by 3 of the authors, and deaths during hospitalization following amputation were classified according to consensus. Results - 31 patients died within 30 days after surgery. 4 deaths were classified as "definitely unavoidable," 4 as "probably unavoidable," and 23 as "FTR." Patients who died had a higher incidence of sepsis, pneumonia, and acute myocardial infarction compared with those alive. A log binominal regression analysis adjusted for age, sex, ASA score, diabetes, nursing home admission, transfemoral amputation (TFA), and BMI showed that the risk of 30-day mortality was increased for TFA (RR =2.3, 95% CI 1.1-4.8) and for patients with diabetes (RR =2.7, 95% CI 1.3-5.6). The FTR rate (patients with 30-day mortality/all patients with a severe postoperative complication) was 30%. Of the FTR deaths, 20 at some point had active lifesaving care curtailed. Interpretation - Future initiatives should be directed at enhanced sepsis and pneumonia prophylactic actions, in addition to close monitoring of hemodynamics in anemic patients, with the potential to further reduce morbidity and mortality rates.

Abstract
INTRODUCTION In the geriatric population, independent mobility is a key factor in determining readiness for discharge following acute hospitalization. The Cumulated Ambulation Score (CAS) is a potentially valuable score that allows day-to-day measurements of basic mobility. The CAS was developed and validated in older patients with hip fracture as an early postoperative predictor of short-term outcome, but it is also used to assess geriatric in-patients with acute medical illness. Despite the fast-accumulating literature on the CAS, to date no systematic review synthesizing its psychometric properties has been published. Therefore, we aimed to provide a comprehensive review of the psychometric properties of the CAS, summarizing the present evidence on this measure as a basis for further research to investigate its applicability across a wider range of functional abilities and care settings. EVIDENCE ACQUISITION A literature search was conducted on research articles published between 2006 and June 2016 in journals indexed by MEDLINE and Scopus databases using as a search item "Cumulated Ambulation Score"[All Fields], and selecting studies that presented a psychometric analysis of the scale. Of 49 studies identified, 17 examined the psychometric properties of the CAS. EVIDENCE SYNTHESIS Most papers dealt with patients after hip fracture surgery, and only 4 studies assessed the CAS psychometric characteristics also in geriatric in-patients with acute medical illness. Two versions of CAS (CAS1 and the more detailed CAS2 version) and two different methods to calculate the total score (1-day and 3-day CAS) were used in the selected papers. Most of the papers assessed reliability and validity, using different statistics, and only one showed evidence of sensitivity to change of the score. CONCLUSIONS This systematic review shows international interest of researchers in the CAS, despite the short time frame since its first publication in 2006. The results support the reliability, validity, and sensitivity to change of the tool. Since different versions of CAS are available and two scores are commonly used, we suggest that clinicians and researchers in the future choose the more detailed CAS2 version, already used by the large majority of studies, and report whether they used the 1- or 3-day score.

Abstract
Background and purpose - Mortality rates following hip fracture (HF) surgery are high. We evaluated the influence of the basic mobility status on acute hospital discharge to 1- and 5-year mortality rates after HF. Patients and methods - 444 patients with HF ≥60 years (mean age 81 years, 77% women) being pre-fracture ambulatory and admitted from their own homes, were consecutively included in an in-hospital enhanced recovery program and followed for 5 years. The Cumulated Ambulation Score (CAS, 0-6 points, 6 points equals independence) was used to evaluate the basic mobility status on hospital discharge. Results - 102 patients with a CAS <6 stayed in the acute ward a median of 22 (15-32) days post-surgery as compared with a median of 12 (8-16) days for those 342 patients who achieved a CAS =6. Overall 1-year mortality was 16%; in those with CAS <6 it was 30% and in those with CAS =6 it was 12%. Corresponding data for 5-year deaths were 78% and 50%. Multivariable Cox regression analysis demonstrated that the likelihood of not surviving the first 5 years after hip fracture was 1.5 times higher for those with a CAS <6 and for men; 2 times higher for those 80 years or older; increased by 50% per point higher ASA grade; and was reduced by 11% per point higher New Mobility Score, when adjusted for the cognitive and fracture type status. Interpretation - Further studies focused on interventions that improve the basic mobility status of patients with HF should be instigated within the early time period following surgery.

Abstract
Introduction: Underestimation of the actual blood loss in patients undergoing nontraumatic transfemoral amputation (TFA) can impact negatively on outcome in these often frail patients, with very limited physiological reserves. The primary aim of this study is to estimate the total blood loss (TBL) after TFA, and second, to evaluate the impact of blood loss on 30-day mortality and medical complications. Methods: A single-center retrospective cohort study conducted from 2013 to 2015. The TBL was calculated on the fourth postoperative day. It was based on the hemoglobin levels, transfusions, and the estimated blood volume. Results: Eighty-one patients undergoing TFA were included for final analysis. The median TBL was 964 mL (interquartile range [IQR]: 443-1558). The intraoperative blood loss (OBL) was 400 mL (IQR: 200-500). The median difference between TBL and OBL was 688 mL (IQR: 124-1075). The patient received red blood cell (RBC) transfusion of a median amount of 2 units. Higher number of transfusions (>2) did not impact the outcome. From multivariable analysis, it was evident that the TBL increased significantly in patients with renal disease prior to surgery, (P = .034). The TBL itself was not independently associated with increased 30-day mortality or medical complications. Conclusion: The TBL after TFAs is significantly greater than the volume estimated intraoperatively and increases significantly in the presence of renal disease prior to surgery. An increased TBL and requirement for RBC transfusion is not directly associated with 30-day mortality or medical complications. A high vigilance for anemia seems advisable when planning for TFA surgery. Research on optimum blood conservation and transfusion strategies during TFA is warranted.

Abstract
AIM To investigate the total blood loss (TBL) and the safety with respect to the re-amputation rate after transtibial amputation (TTA) conducted with and without a tourniquet.
METHODS The study was a single-centre retrospective cohort study of patients with a primary TTA admitted between January 2013 and April 2015. All patients with a primary TTA were assessed for inclusion if the amputation was performed because of arteriosclerosis or diabetic complications. All patients underwent a standardized TTA procedure that was performed approximately 10 cm below the knee joint and performed with sagittal flaps. The pneumatic tourniquet, when used, was inflated around the femur to a pressure of 100 mmHg above the systolic blood pressure. The number of blood transfusions within the first four postoperative days was recorded. The intraoperative blood loss (OBL), which is defined as the volume of blood lost during surgery, was determined from the suction volume and by the weight difference of the surgical dressings. The trigger for a blood transfusion was set at a decrease in the Hgb level < 9.67 g/dL (6 mmol/L). Transfusions were performed with pooled red blood cells containing 245 mL per portion, which equals 55 g/L of haemoglobin. The TBL during the first four postoperative days was calculated based on the haemoglobin level and the estimated blood volume. The re-amputation rate was evaluated within 30 d.
RESULTS Seventy-four out of 86 consecutive patients who underwent TTA within the two-year study period were included in the analysis. Of these, 38 were operated on using a tourniquet and 36 were operated on without using a tourniquet. There were no significant preoperative differences between the groups. The patients in both groups had a postoperative decrease in their Hgb level compared with preoperative baseline values. The patients operated on using a tourniquet received approximately three millilitres less blood transfusion per kilogram body weight compared with patients operated on without a tourniquet. The duration of surgery was shorter and the OBL was less for the tourniquet group than the non-tourniquet group, whereas no significant difference was observed for the TBL. The TBL median was 859 mL (IQR: 383-1315) in the non-tourniquet group vs 737 mL (IQR: 331-1218) in the tourniquet group (P = 0.754). Within the 30-d follow-up period, 9 patients in the tourniquet group and 11 in the non-tourniquet group underwent a re-amputation at the trans-femoral level. The use of a tourniquet showed no statistically significant association with the 30-d re-amputation at the femur level in the multiple logistic regression model (P = 0.78). The only variable with a significant association with re-amputation was age (OR = 1.07; P = 0.02).
CONCLUSION The results indicate that tourniquets do not cause severe vascular damage with an increased postoperative bleeding or failure rate as the result.

Abstract
AIM To assess whether the surgical apgar score (SAS) is a prognostic tool capable of identifying patients at risk of major complications following lower extremity amputations surgery.
METHODS This was a single-center, retrospective observational cohort study conducted between January 2013 and April 2015. All patients who had either a primary transtibial amputation (TTA) or transfemoral amputation (TFA) conducted at our institution during the study period were assessed for inclusion. All TTA patients underwent a standardized one-stage operative procedure (ad modum Persson amputation) performed approximately 10 cm below the knee joint. All TTA procedures were performed with sagittal flaps. TFA procedures were performed in one stage with amputation approximately 10 cm above the knee joint, performed with anterior/posterior flaps. Trained residents or senior consultants performed the surgical procedures. The SAS is based on intraoperative heart rate, blood pressure and blood loss. Intraoperative parameters of interest were collected by revising electronic health records. The first author of this study calculated the SAS. Data regarding major complications were not revealed to the author until after the calculation of SAS. The SAS results were arranged into four groups (SAS 0-4, SAS 5-6, SAS 7-8 and SAS 9-10). The cohort was then divided into two groups representing low-risk (SAS ≥ 7) and high-risk patients (SAS < 7) using a previously established threshold. The outcome of interest was the occurrence of major complications and death within 30-d of surgery.
RESULTS A logistic regression model with SAS 9-10 as a reference showed a significant linear association between lower SAS and more postoperative complications [all patients: OR = 2.00 (1.33-3.03), P = 0.001]. This effect was pronounced for TFA [OR = 2.61 (1.52-4.47), P < 0.001]. A significant increase was observed for the high-risk group compared to the low-risk group for all patients [OR = 2.80 (1.40-5.61), P = 0.004] and for the TFA sub-group [OR = 3.82 (1.5-9.42), P = 0.004]. The AUC from the models were estimated as follows: All patients = [0.648 (0.562-0.733), P = 0.001], for TFA patients = [0.710 (0.606-0.813), P < 0.001] and for TTA patients = [0.472 (0.383-0.672), P = 0.528]. This indicates moderate discriminatory power of the SAS in predicting postoperative complications among TFA patients.
CONCLUSION SAS provides information regarding the potential development of complications following TFA. The SAS is especially useful when patients are divided into high- and low-risk groups.

Abstract
Background and purpose - Historically, high 30-day and 1-year mortality post-amputation rates (> 30% and 50%, respectively) have been reported in patients with a transtibial or higher non-traumatic lower extremity amputation (LEA). We evaluated whether allocating experienced staff and implementing an enhanced, multidisciplinary recovery program would reduce the mortality rates. We also determined factors that influenced mortality rates. Patients and methods - 129 patients with a LEA were consecutively included over a 2-year period, and followed after admission to an acute orthopedic ward. Mortality was compared with historical and concurrent national controls in Denmark. Results - The 30-day and 1-year mortality rates were 16% and 37%, respectively, in the intervention group, as compared to 35% and 59% in the historical control group treated in the same orthopedic ward. Cox proportional harzards models adjusted for age, sex, residential and health status, the disease that caused the amputation, and the index amputation level showed that 30-day and 1-year mortality risk was reduced by 52% (HR =0.48, 95% CI: 0.25-0.91) and by 46% (HR =0.54, 95% CI: 0.35-0.86), respectively, in the intervention group. The risk of death was increased for patients living in a nursing home, for patients with a bilateral LEA, and for patients with low health status. Interpretation - With similarly frail patient groups and instituting an enhanced program for patients after LEA, the risks of death by 30 days and by 1 year after LEA were markedly reduced after allocating staff with expertise.

Abstract
AIM: To investigate the feasibility of a 6-wk progressive strength-training programme commenced shortly after hip fracture surgery in community-dwelling patients.
METHODS: This prospective, single-blinded cohort study evaluated 31 community-dwelling patients from four outpatient geriatric health centres aged 60 years or older, who started a 6-wk programme at a mean of 17.5 ± 5.7 d after hip fracture surgery. The intervention consisted primarily of progressive fractured knee-extension and bilateral leg press strength training (twice weekly), with relative loads commencing at 15 and increasing to 10 repetitions maximum (RM), with three sets in each session. The main measurements included progression in weight loads, hip fracture-related pain during training, maximal isometric knee-extension strength, new mobility score, the timed up and go test, the 6-min walk test and the 10-meter fast speed walk test, assessed before and after the programme.
RESULTS: Weight loads in kilograms in the fractured limb knee-extension strength training increased from 3.3 ± 1.5 to 5.7 ± 1.7 and from 6.8 ± 2.4 to 7.7 ± 2.6, respectively, in the first and last 2 wk (P < 0.001). Correspondingly, the weight loads increased from 50.3 ± 1.9 to 90.8 ± 40 kg and from 108.9 ± 47.7 to 121.9 ± 54 kg in the bilateral leg press exercise (P < 0.001). Hip fracture-related pain was reduced, and large improvements were observed in the functional outcome measurements, e.g., the 6-min walk test improved from 200.6 ± 79.5 to 322.8 ± 68.5 m (P < 0.001). The fractured limb knee-extension strength deficit was reduced from 40% to 17%, compared with the non-fractured limb. Ten patients reported knee pain as a minor restricting factor during the last 10 RM knee-extension strength-training sessions, but with no significant influences on performance.
CONCLUSION: Progressive strength training, initiated shortly after hip fracture surgery, seems feasible and does not increase hip fracture-related pain. Progressive strength training resulted in improvement, although a strength deficit of 17% persisted in the fractured limb compared with the non-fractured limb.

Abstract
Having a hip fracture is considered one of the most fatal fractures for elderly people, resulting in impaired function, and increased morbidity and mortality. This challenges clinicians in identifying patients at risk of worse outcome, in order to optimise and intensify treatment in these patients. A variety of factors such as age, prefracture function and health status, fracture type, pain, anaemia, muscle strength, and the early mobility level have been shown to influence patient outcome. Thus, the outcome of patients with hip fracture is considered multi-factorial, and can therefore not be related to just one or two single factors. The current article reviews important factors affecting the functional prognosis, and clinicians are encouraged to include all factors potentially influencing the outcome of patients with hip fracture in their individualised treatment and rehabilitation plan. Especially, older age and having a low prefracture functional level are considered strong factors.

Abstract
OBJECTIVE To examine whether changes in knee-extension strength and functional performance are related to knee swelling after total knee arthroplasty (TKA). DESIGN Prospective, descriptive, hypothesis-generating study. SETTING A fast-track orthopedic arthroplasty unit at a university hospital. PARTICIPANTS Patients (N=24; mean age, 66y; 13 women) scheduled for primary unilateral TKA were investigated 1 week before surgery and on the day of hospital discharge 2.4 days postsurgery. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES We assessed all patients for knee-joint circumference, knee-extension strength, and functional performance using the Timed Up & Go, 30-second Chair Stand, and 10-m fast speed walking tests, together with knee pain during all active test procedures. RESULTS All investigated variables changed significantly from pre- to postsurgery independent of knee pain. Importantly, knee circumference increased (knee swelling) and correlated significantly with the decrease in knee-extension strength (r=-.51; P=.01). Reduced fast-speed walking correlated significantly with decreased knee-extension strength (r=.59; P=.003) and decreased knee flexion (r=.52; P=.011). Multiple linear regression showed that knee swelling (P=.023), adjusted for age and sex, could explain 27% of the decrease in knee-extension strength. Another model showed that changes in knee-extension strength (P=.009) and knee flexion (P=.018) were associated independently with decreased performance in fast-speed walking, explaining 57% of the variation in fast-speed walking. CONCLUSIONS Our results indicate that the well-known finding of decreased knee-extension strength, which decreases functional performance shortly after TKA, is caused in part by postoperative knee swelling. Future studies may look at specific interventions aimed at decreasing knee swelling postsurgery to preserve knee-extension strength and facilitate physical rehabilitation after TKA.

Abstract
OBJECTIVE To examine the number of trials needed to achieve performance stability of the Timed Up & Go (TUG) test using a standardized walking aid in patients with hip fracture who are allowed full weight bearing (FWB). DESIGN Prospective methodologic study. SETTING An acute 14-bed orthopedic hip fracture unit. PARTICIPANTS Patients (N=122; 89 women, 33 men) with hip fracture with a median age (25%-75%, quartiles) of 80 (67-85) years performed the TUG on hospital discharge to their own home (n=115) or further inpatient rehabilitation (n=7). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES After a demonstration by a physical therapist how to perform the TUG with a standardized walking aid (a 4-wheeled rollator), the patients performed 6 timed TUG trials with up to 1-minute seated rest intervals. The participants were given a few minutes to familiarize with the rollator before commencing the timed trials. Repeated-measures analysis of variance (ANOVA) with Bonferroni corrections were used to examine the number of trials needed to ensure statistically stable TUG scores. RESULTS A total of 106 (87%) patients performed all 6 TUG trials, while 120 patients performed a minimum of 3 timed trials. Repeated-measures ANOVAs of both groups showed that TUG scores improved significantly (P< or =.007) up to and including the third TUG trial. CONCLUSIONS These results suggest that the original TUG manual, described as 1 practice trial followed by 1 timed trial, needs modification when used in patients with hip fracture who are allowed FWB. The best (fastest) of 3 timed TUG trials performed with a standardized walking aid is recommended.

Abstract
BACKGROUND AND PURPOSE Clinicians need valid and easily applicable predictors of outcome in patients with hip fracture. Adjusting for previously established predictors, we determined the predictive value of the New Mobility score (NMS) for in-hospital outcome in patients with hip fracture. PATIENTS AND METHODS We studied 280 patients with a median age of 81 (interquartile range 72-86) years who were admitted from their own homes to a special hip fracture unit. Main outcome was the regain of independence in basic mobility, defined as. independence in getting in and out of bed, sitting down and standing up from a chair, and walking with an appropriate walking aid. The Cumulated Ambulation score was used to evaluate basic mobility. Predictor variables were NMS functional level before fracture, age, sex, fracture type, and mental and health status. RESULTS Except for sex, all predictor variables were statistically significant in univariate testing. In multiple logistic regression analysis, only age, NMS functional level before fracture, and fracture type were significant. Thus, patients with a low prefracture NMS and/or an intertrochanteric fracture would be 18 and 4 times more likely not to regain independence in basic mobility during the hospital stay, respectively, than patients with a high prefracture level and a cervical fracture, respectively. The model was statistically stable and correctly classified 84% of cases. INTERPRETATION The NMS functional level before fracture, age, and fracture type facilitate prediction of the in-hospital rehabilitation potential after hip fracture surgery.

UNLABELLED Kristensen MT, Bandholm T, Holm B, Ekdahl C, Kehlet H. Timed Up & Go test score in patients with hip fracture is related to the type of walking aid. OBJECTIVE To determine the relationship between Timed Up & Go (TUG) test scores and type of walking aid used during the test, and to determine the feasibility of using the rollator as a standardized walking aid during the TUG in patients with hip fracture who were allowed full weight-bearing (FWB). DESIGN Prospective methodological study. SETTING An acute orthopedic hip fracture unit at a university hospital. PARTICIPANTS Patients (N=126; 90 women, 36 men) with hip fracture with a mean age +/- SD of 74.8+/-12.7 years performed the TUG the day before discharge from the orthopedic ward. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The TUG was performed with the walking aid the patient was to be discharged with: a walker (n=88) or elbow crutches (n=38). In addition, all patients also performed the TUG using a rollator. RESULTS Patients who performed the TUG with a walker were on average 13.6 (95% confidence interval [CI], 11.2-16.1) seconds faster using a rollator compared with the walker (P<.001). Correspondingly, patients who performed the TUG with crutches were on average 3.5 (95% CI, 1.5-5.4) seconds faster using a rollator compared with elbow crutches (P=.001). In both patient groups, the between walking-aid scores were strongly correlated (r>.833, P<.001). CONCLUSIONS TUG scores are significantly related to the type of walking aid used during the test in patients with hip fracture who are allowed FWB when discharged from the hospital, but all patients were able to perform the TUG using the rollator as a standardized walking aid. Our findings indicate the importance of using a standardized walking aid when evaluating changes or comparing TUG scores in patients with hip fracture.

Abstract
BACKGROUND Post-surgery thigh edema, loss of knee-extension strength, and reduced physical performance are common following a hip fracture. It is not known if knee-extension strength and physical performance are related to the edema and fracture type. The aim of this study was to examine the influence of fracture type and post-surgery edema on physical performances in patients with hip fracture. METHODS Fifteen women and five men admitted from their own home to an acute orthopedic hip fracture unit were examined. Ten had cervical and ten had intertrochanteric fractures. Correlations between fracture type and thigh edema in the fractured limb (% non-fractured) to physical performances of basic mobility, postural control (sway), and isometric knee-extension strength were examined. All measures, except those of basic mobility, were conducted at the time of discharge, 8.5 days post-surgery. FINDINGS Patients with intertrochanteric fractures had greater edema (111% non-fractured limb) compared with cervical fractures (104% non-fractured, P<0.001). Thigh edema was significantly correlated to lower scores of basic mobility (r=-0.61, P=0.004), reduced postural control (r=0.67, P=0.001), and fractured limb knee-extension strength deficit ([% non-fractured], r=-0.77, P<0.001), explaining between 32% and 59% of the variance (r(2)) in performances. INTERPRETATION Our results indicate that fracture type and the corresponding thigh edema are important factors influencing physical performances after hip fracture. These findings have important implications for rehabilitation programs and for further research in patients with hip fracture.

Abstract
BACKGROUND Hip fracture patients experience high pain levels during postoperative rehabilitation. The role of surgical technique on postoperative pain has not been evaluated previously. METHODS One hundred and seventeen hip fracture patients were included in a descriptive prospective study. All patients received continuous epidural analgesia and were treated according to a standardized perioperative rehabilitation programme. Resting pain, pain on hip flexion, and walking were measured during daily physiotherapy sessions on a verbal five-point rating scale during the first four postoperative days. Patients were stratified into four groups according to surgical procedure: screws or pins, arthroplasty, dynamic hip screw (DHS), and intra-medullary hip screw (IMHS). RESULTS Cumulated pain levels were significantly different between surgical procedures both for hip flexion (P=0.002) and for walking (P=0.02) with highest dynamic pain levels for patients who had either DHSs or IMHSs compared with arthroplasty or parallel implants. There were significant negative correlations between ambulatory capacity assessed by the cumulated ambulation score and both the dynamic cumulated pain scores on hip flexion (r=-0.43, P<0.001) and walking (r=-0.36, P=0.004). CONCLUSIONS Postoperative pain levels after surgery for hip fracture are dependent on the surgical procedure, which should be taken into account in future studies of analgesia and rehabilitation.

Abstract
OBJECTIVE To validate the cumulated ambulation score as an early postoperative predictor of short-term outcome in hip fracture patients. DESIGN Prospective, descriptive study. SETTING An orthopaedic hip fracture unit in a university hospital. PATIENTS Four hundred and twenty-six consecutive hip fracture patients with an independent walking function admitted from their own home. Rehabilitation followed a well-defined multimodal rehabilitation regimen and discharge criteria. MAIN OUTCOME MEASURE Admission tests with a new mobility score to assess prefracture functional mobility and a short mental score for cognitive dysfunction were performed. On the first three postoperative days patients were assessed with the cumulated ambulation score consisting of a cumulated assessment of simple ambulation characteristics with a score from 0 to 18 (fully mobile). The three assessments were correlated to short-term outcome parameters. RESULTS The cumulated ambulation score was a highly significant predictor for length of hospitalization, time to discharge status, 30-day mortality and postoperative medical complications (P < 0.001 for all). The cumulated ambulation score was superior in its association with all postoperative outcome parameters to both the New Mobility Score and the mental score. A cumulated ambulation score of > or = 10 correlated with a 99% survival at one month and 93% discharge to own home. CONCLUSION The cumulated ambulation score is a potentially valuable score for early prediction of short-term postoperative outcome after hip fracture surgery.

Abstract
BACKGROUND AND PURPOSE Previous studies of Timed "Up & Go" Test (TUG) scores as a predictor of falls were based primarily on retrospective data, and no prospective studies of the TUG for predicting falls in people with hip fracture are available. The purpose of this study was to determine whether TUG scores obtained upon discharge from an acute orthopedic hip fracture unit can predict falls in people with hip fracture during a 6-month follow-up period. SUBJECTS The subjects included in this study were 79 consecutive elderly people who had hip fractures and were able to perform the TUG when discharged directly to their own homes or to assisted living facilities from a specialized acute orthopedic hip fracture unit, with 59 (75%) being able to participate in the follow-up interview. METHODS In this prospective study, all subjects were contacted for a 6-month follow-up interview about falls since discharge from the hospital. The score on the TUG performed at discharge (median of 10 days after surgery) was compared with the New Mobility Score, which describes functional level before the fracture and mental status on admission, sex, type of fracture, residence, and walking aids before and after the fracture. All subjects followed a well-defined care plan with multimodal fast-track rehabilitation including an intensive physical therapy program comprising 2 daily sessions; discharge was in accordance with standardized criteria. Analyses and correlations of all variables were examined for prediction of falls, and sensitivity, specificity, predictive values, and likelihood ratios were calculated. Falls were classified as "none" or as "1 or more." RESULTS Among the 59 subjects in the follow-up group, 19 subjects (32%) experienced 1 or more falls in the period since discharge; 4 of these falls resulted in new hip fractures. The TUG performed at discharge with a cutoff point of 24 seconds was the only parameter that significantly predicted falls during the 6-month follow-up period, with a negative likelihood ratio of 0.1 to be a faller as a non-faller. DISCUSSION AND CONCLUSION The results suggest that the TUG is a sensitive measure for identifying people with hip fracture at risk for new falls, and it should be part of future outcome measures to decide for whom preventive measures against falls should be instituted.
