Thromboprophylaxis only during hospitalisation in fast-track hip and knee arthroplasty, a prospective cohort study.

ABSTRACT: International guidelines recommend thrombosis prophylaxis after total hip arthroplasty (THA) and total knee arthroplasty (TKA) for up to 35 days. However, previous studies often have hospital stays (length of stay; LOS) of 8-12 days and not considering early mobilisation, which may reduce incidence of venous thromboembolic events (VTE). We investigated the incidence of any symptomatic thromboembolic events (TEEs) with only in-hospital prophylaxis if LOS ?5 days after fast-track THA and TKA.A prospective descriptive multicentre cohort study in fast-track THA and TKA from February 2010 to December 2011, with complete 90-day follow-up through the Danish National Patient Registry and patient files.6 Danish high-volume centres with a similar standardised fast-track setup, including spinal anaesthesia, opioid-sparing analgesia, early mobilisation, functional discharge criteria and discharge to own home.4924 consecutive unselected unilateral primary THA and TKAs in patients ?18 years with no preoperative use of continuous 'potent' anticoagulative therapy (vitamin K antagonists).Prophylaxis with low-molecular-weight heparin or factor Xa-inhibitors only during hospitalisation when LOS ?5 days.Incidence of symptomatic TEE-related, VTE-related and VTE-related mortality ?90 days postoperatively.LOS ?5 days and thromboprophylaxis only during hospitalisation occurred in 4659 procedures (94.6% of total). Median LOS and prophylaxis duration was 2 days (IQR 2-3) with 0.84% (95% CI 0.62% to 1.15%) TEE and 0.41% (0.26% to 0.64%) VTE during 90-day follow-up. VTE consisted of five pulmonary embolisms (0.11% (0.05% to 0.25%)) and 14 deep venous thrombosis (0.30% (0.18% to 0.50%)). There were four (0.09% (0.04% to 0.23%)) surgery-related deaths, of which 1 (0.02% (0.00% to 0.12%)) was due to pulmonary embolism, and 6 (0.13% (0.06% to 0.28%)) deaths of unknown causes after discharge.The low incidence of TEE and VTE suggests that in-hospital prophylaxis only, is safe in fast-track THA and TKA patients with LOS of ?5 days. Guidelines on thromboprophylaxis may need reconsideration in fast-track elective surgery.ClinicalTrials.gov: NCT01557725.

Project description:OBJECTIVES:Construction of a simple preoperative risk score for patients in high risk of potentially preventable 'medical' complications. Secondary objectives were to construct simple preoperative risk scores for 'severe medical', 'surgical' and 'total' potentially preventable complications. DESIGN:Prospective observational study. SETTING:Elective primary unilateral total hip and knee arthroplasty with prospectively collected preoperative patient characteristics; similar standardised fast-track protocols; evaluation of complications through discharge and medical records; and complete 90 days follow-up through nationwide databases. PARTICIPANTS:8373 consecutive unselected total hip arthroplasty (THA) and knee arthroplasty from January 2010 to November 2012. RESULTS:There were 557 procedures (6.4%) followed by potentially preventable complications resulting in hospitalisation >4 days or readmission. Of 22 preoperative characteristics, 7 were associated with 379 (4.2%) potentially preventable 'medical' complications. Patients with ? 2 of the following, age ? 80 years, anticoagulant therapy, pulmonary disease, pharmacologically treated psychiatric disorder, anaemia and walking aids, composed 19.1% of the procedures; 55.7% constituted potentially preventable 'medical' complications that were mainly falls, mobilisation issues, pneumonias and cardiac arrhythmias. The number needed to be treated for a hypothetical intervention leading to 25% reduction in potentially preventable 'medical' complications was 34. THA, use of walking aids and cardiac disease were associated with 189 (2.2%) 'surgical' complications, but no clinically relevant preoperative prediction was possible. CONCLUSIONS:Preoperative identification of patients at high risk of preventable 'medical', but not 'surgical', complications is statistically possible. However, clinical relevance is limited. Future risk indices should differ between 'medical' and 'surgical' complications, and also consider 'preventability' of these. TRIAL REGISTRATION NUMBER:NCT01515670.

Project description:BackgroundEarly postoperative mobilization is essential for early functional recovery but can be inhibited by postoperative orthostatic intolerance (OI). Postoperative OI is common after major surgery, such as total knee arthroplasty (TKA). However, limited data are available after less extensive surgery, such as unicompartmental knee arthroplasty (UKA). We, therefore, investigated the incidence of OI as well as cardiovascular and tissue oxygenation responses during early mobilization after UKA.MethodsThis prospective single-centre observational study included 32 patients undergoing primary UKA. Incidence of OI and cardiovascular and tissue oxygenation responses during mobilization were evaluated preoperatively, at 6 and 24 h after surgery. Perioperative fluid balance, bleeding, surgery duration, postoperative hemoglobin, pain during mobilization and opioid usage were recorded.ResultsDuring mobilization at 6 h after surgery, 4 (14%, 95%CI 4-33%) patients experienced OI; however, no patients terminated the mobilization procedure prematurely. Dizziness and feeling of heat were the most common symptoms. OI was associated with attenuated systolic and mean arterial blood pressure responses in the sitting position (all p < 0.05). At 24 h after surgery, 24 (75%) patients had already been discharged, including three of the four patients with early OI. Only five patients were available for measurements, two of whom experienced OI; one terminated the mobilization procedure due to intolerable symptoms. We observed no statistically significant differences in perioperative fluid balance, bleeding, surgery duration, postoperative hemoglobin, pain, or opioid usage between orthostatic intolerant and tolerant patients.ConclusionsThe incidence of orthostatic intolerance after fast-track unicompartmental knee arthroplasty is low (~ 15%) and is associated with decreased orthostatic pressure responses. Compared to the previously described orthostatic intolerance incidence of ~ 40% following total knee arthroplasty, early orthostatic intolerance is uncommon after unicompartmental knee arthroplasty, suggesting a procedure-specific component.Trial registrationProspectively registered at ClinicalTrials.gov; registration number: NCT04195360, registration date: 13.12.2019.

Project description:BackgroundLoading and contraction failure (muscular exhaustion) are strength training variables known to influence neural activation of the exercising muscle in healthy subjects, which may help reduce neural inhibition of the quadriceps muscle following total knee arthroplasty (TKA). It is unknown how these exercise variables influence knee pain after TKA.ObjectiveTo investigate the effect of loading and contraction failure on knee pain during strength training, shortly following TKA.DesignCross-sectional study.SettingConsecutive sample of patients from the Copenhagen area, Denmark, receiving a TKA, between November 2012 and April 2013.ParticipantsSeventeen patients, no more than 3 weeks after their TKA.Main outcome measuresIn a randomized order, the patients performed 1 set of 4 standardized knee extensions, using relative loads of 8, 14, and 20 repetition maximum (RM), and ended with 1 single set to contraction failure (14 RM load). The individual loadings (kilograms) were determined during a familiarization session >72 hours prior. The patients rated their knee pain during each repetition, using a numerical rating scale (0-10).ResultsTwo patients were lost to follow up. Knee pain increased with increasing load (20 RM: 3.1±2.0 points, 14 RM: 3.5±1.8 points, 8 RM: 4.3±2.5 points, P = 0.006), and repetitions to contraction failure (10% failure: 3.2±1.9 points, 100% failure: 5.4±1.6 points, P<0.001). Resting knee pain 60 seconds after the final repetition (2.7±2.4 points) was not different from that recorded before strength training (2.7±1.8 points, P = 0.88).ConclusionBoth loading and repetitions performed to contraction failure during knee- extension strength-training, increased post-operative knee pain during strength training implemented shortly following TKA. However, only the increase in pain during repetitions to contraction failure exceeded that defined as clinically relevant, and was very short-lived.Trial registrationClinicalTrials.gov NCT01729520.
