The purpose of this prospective audit was to assess the efficacy of local infiltration analgesia in relieving postoperative pain following knee replacement surgery. Methods and materials: Data was collected on 61 consecutive patients undergoing knee replacement. They formed 2 groups. Patients in Group I (n=33) had 30 mls of Bupivacaine 0.5%, Ketoralac 30 mg, 0.75ml of adrenaline 1:1000 concentration made up to100mls with normal saline while patients in Group II (n=28) had either patient controlled analgesia (PCA) or regional nerve blocks. The group I patients had the local analgesia cocktail infiltrated into the soft tissues before wound closure. Majority of these patients had spinal anaesthesia supplemented with sedation while some had general anaesthesia supplemented with regional nerve blocks. All the patients were prescribed morphine as rescue analgesia and patacetamol/co-codamol and/or naproxene as supplemental analgesia. Pain was assessed with Numerical Rating Scale (NRS 0 – 10) at 1 hr, 3 hr, 6 hr and 8 hrs post-operatively. Results: The two groups were well matched for age, sex, ASA grade and body mass index. Pain control was generally satisfactory for group I (NRS range 0 – 2) compared to group II (NRS range 0 – 7). Most patients did not require morphine for post-operative pain control in group I (18/27 pts) while additional analgesics were not needed until 6 hours in this group. They were able to mobilise with assistance earlier compared to the other group. Moreover the pain levels as assessed by pain scores were lower with group I patients compared to group II patients. The nursing level of intensity was lower in group I patients as monitoring of PCA was not required compared to group II patients. Conclusion: Local infiltration analgesia is practical, simple and safe procedure with good efficacy in relieving pain after knee surgery. Moreover monitoring levels are reduced relieving nursing staff to concentrate on other duties

Local infiltration analgesia is a relatively novel technique developed for effective pain control following total knee replacement, reducing requirements of epidural or parenteral post-operative analgesia. The study aimed to investigate the anatomical spread of Local Infiltration Analgesia (LIA) used intra-operatively in total knee arthroplasty (TKA) and identify the nerve structures reached by the injected fluid. Six fresh-frozen cadaveric lower limbs were injected with 180ml of a solution of latex and India ink to enable visualisation. Injections were done according to our standardised LIA technique. Wounds were closed and limbs were placed flat in a freezer at −20°C for two weeks. Limbs were then either sliced or dissected to identify solution locations. Injected solution was found from the proximal thigh to the middle of the lower leg. The main areas of concentration were the popliteal fossa, the anterior aspect of the femur and the subcutaneous tissue of the anterior aspect of the knee. There was less solution in the lower popliteal fossa. The solution was found to reach the majority of the terminal branches of the tibial, fibular and obturator nerves. Overall, there was good infiltration of nerves supplying the knee. The lack of infiltration into the lower popliteal fossa suggests more fluid or a different injection point could be used. The solution that travelled distally to the extensor muscles of the lower leg probably has no beneficial analgesic effect for a TKA patient. This LIA technique reached most nerves that innervate the knee joint which supports the positive clinical results from this LIA technique. However, there may be scope to optimise the injection sites


Background. Total knee arthroplasty is associated with early postoperative pain. Appropriate pain management is important to facilitate postoperative rehabilitation and positive functional outcomes. This study compares outcomes in TKA with three techniques; local infiltration analgesia, single shot femoral nerve block and intrathecal morphine. Methods. Forty-five patients undergoing elective primary Total Knee Arthroplasty (TKA) with were randomized into one of three groups in a double blind proof of concept study. Study arm 1 received local infiltration analgesia ropivacaine intra-operatively, an elastomeric device of ropivacaine for 24 hours post-op. Study arm 2 received a femoral nerve block of ropivacaine with placebo local infiltration analgesia and placebo intrathecal morphine. Study arm 3 received intrathecal morphine, placebo femoral nerve block and placebo local infiltration analgesia. All patients received standardized pre-operative, intraoperative and Post-operative analgesic medication. Participants were mobilized at 4 hrs, 24hrs and 48 hrs post operation. Range of Motion, Visual Analogue Scale (VAS) pain intensity scores and two minute walk test and Timed Up and Go test were performed. Postoperative use of analgesic drugs was recorded. Knee Society Score (KSS), Oxford Knee Score and Knee Injury and Osteoarthritis Outcome Score (KOOS) were completed at preoperative and 6 weeks post op. Results. Assessment of the efficacy of analgesia will be conducted using VAS pain scores collected preoperatively, 0–24hrs and 24–48 hours postoperatively between the three randomized groups. Frequency of use of other analgesia and need for PCA will be compared between groups at 0–24hr and 24–48hrs post operatively. The assessment of functional outcomes will be measured between the three groups by comparing the ability to mobilize the first 4 hrs after surgery, maximal flexion and extension, two minute walk test and timed up-and-go preoperatively, on postoperative day 1 and 2 and 6 weeks. Patient reported outcome measures KSS, Oxford Knee score and KOOS will be compared for the three study arms. Conclusion. Results from the study will provide important information for the management of TKA in the hospital setting. The comparison of the three commonly used analgesic techniques and mobilization outcomes are pertinent for physiotherapy and rehabilitation management, anaesthetic specialists, nursing staff, orthopaedic surgeons and patients


Total knee arthroplasty is associated with early postoperative pain. Appropriate pain management is important to facilitate postoperative rehabilitation and positive functional outcomes. This study compares outcomes in TKA with three techniques; local infiltration analgesia, single shot femoral nerve block and intrathecal morphine. Methods. Forty-five patients undergoing elective primary Total Knee Arthroplasty (TKA) with were randomized into one of three groups in a double blind proof of concept study. Study arm 1 received local infiltration analgesia ropivacaine intra-operatively, an elastomeric device of ropivacaine for 24 hours post-op. Study arm 2 received a femoral nerve block of ropivacaine with placebo local infiltration analgesia and placebo intrathecal morphine.

Range of Motion, Visual Analogue Scale (VAS) pain intensity scores and two minute walk test and Timed Up and Go test were performed. Postoperative use of analgesic drugs was recorded. Knee Society Score (KSS), Oxford Knee Score and Knee Injury and Osteoarthritis Outcome Score (KOOS) were completed at preoperative and 6 weeks post op. Results. Preliminary results of 32 participants convey the positive outcomes after total knee replacement demonstrated by the improvement in Oxford Knee Score and Knee Osteoarthritis Outcome score. There are marked improvements in the 2-minute walk tests at the six week time-point. At day one post-operative only 5 participants were unable to walk. Patient-controlled analgesia was used on 5 occasions on day one, 2 of which continued on day two. Sedation scores were recorded in six participants on day one and 2 on day two. Nausea was reported in 5 cases on day one and 9 on day two. Urinary catheter was needed in 5 cases on day one. Importantly the study remains blinded, therefore an analysis of the three study arms is not available and is therefore currently difficult to report on the statistical significance. There will be further assessment of the efficacy of analgesia using VAS pain scores, analgesia consumption and side effects collected preoperatively, 0–24hrs and 24–48 hours postoperatively between the three randomized groups. The assessment of functional outcomes will be measured between the three groups by comparing the ability to mobilize the first 4 hrs after surgery, maximal flexion and extension, two minute walk test and timed up-and-go preoperatively, on postoperative day 1 and 2 and 6 weeks. Conclusion. Results from the study will provide important information for the management of TKA in the hospital setting. We anticipate completion of all 45 surgeries in the next 2 months. The Blinding codes with be broken thereafter and full data analysis performed. The comparison of the three commonly used analgesic techniques and mobilization outcomes will allow enhanced management of patient's post-operative pain with earlier discharge from hospital an lower complication rates

Local infiltration analgesia (LIA) is promoted as an effective treatment modality for pain control after total knee arthroplasty (TKA) (1). A mixture of drugs is used to provide a multimodal analgesic effect. Previous studies reported that the use of these drugs is safe. After we carefully implemented a LIA study protocol in our practice, concerns raised about patient safety with probably higher infection rates. This forced us to perform an interim analysis after the first 58 cases. 58 patients underwent a unilateral TKA with a standardised LIA protocol (2), which consisted of a mixture of ropivacaine, epinephrine, and triamcinolone acetonide. Complications, knee function and patient satisfaction scores were prospectively recorded during regular outpatient control. Four patients (6.9%) presented with signs of periprosthetic joint infection (PJI) within two months after surgery. Baseline characteristics were similar between the infected and non infected group. All infections were treated with debridement and retention, and antimicrobial treatment was started. One patient who suffered an infection died during followup. At two years followup all implants could be retained. Knee function and KSS score were acceptable for the patients who suffered PJI. There is no consensus on the combination of drugs used for LIA. The application of corticosteroids in LIA is reported to be safe (3), but arguable results about the injection of local corticosteroids around knee arthroplasty surgery in the past have raised suspicion in literature (4). Combined with our unacceptable high rate of PJI, we believe that the current body of evidence, with small heterogeneous series, does not support the safe use of corticosteroids in LIA

Background: Recent studies have shown that local infiltration analgesia (LIA) improves outcome after total hip replacement (THA). No detailed information does exist to its influence on length of stay (LOS) after surgery. In this study we have evaluated LOS, pain treatment, mobilization, postoperative nausea and vomiting (PONV) and satisfaction in a period before and after implementing LIA in our department. Patients and Methods: Patients diagnosed with primary osteoarthrosis of the hip scheduled for unilateral uncemented or hybrid THA were included in the study. All cases were recognized from a local database with prospective collected data on all patients undergoing THA in our department. Total 100 consecutive patients who did not have LIA from September 1st 2006 were compared with 100 consecutive patients who received LIA from September 1st 2007. The two groups were unmatched and no patients were excluded. The solution used for LIA consisted of 200 mg Ropivacain, 30 mg Ketorolac and 1 mg Adrenaline dissolved in 100 ml isotone NaCl. Results: Patients in the two groups were similar in regard to gender, age, body mass index (BMI) and ASA group, but did differ in duration of the surgical approach, the latter group having treatment with LIA in average had a 20 minuts shorter surgical approach. The patients who received LIA had reduced LOS, mean 3.8 days compared to 5.1 days in the gropu not treated with LIA (p< 0.001). Moreover, patients treated with LIA were significant more satisfied (p< 0.05) compared to the group who did not receive LIA. Moreover, patients treated with LIA were more frequently mobilized on day 1 after surgery (p< 0,001) and day 3 as well (p< 0.05). Also, patients treated with LIA had significantly reduced PONV on the day of operation (p< 0.05) and well as they consumed more nutrition (p< 0.001) the day after the operation. There was no difference in pain-score between the two groups except on day 3 (p< 0.05) in activity and at rest on the day of discharge (p< 0.05). No wound complications could be shown in any of the groups during the first 6 weeks after surgery. Interpretation: Introducing LIA in our department changed the postoperative period detailed in several ways for patients undergoing THA. This study document that operative wound infiltration with multimodal drugs reduced LOS after THA, even though the reduced duration of operation may be some of the explanation. Moreover, LIA resulted in better mobilisation, less PONV and more satisfied patients. We recommend all unit undertaking THA to implement LIA in their daily praxis

Background

The degree of postoperative pain is usually moderate to severe following Total Hip Arthroplasty (THA). Comfort and lack of pain are important for optimal mobilization and earlier home discharge.

Aim

To evaluate the efficacy and safety of Ropivacaine, a long- acting local anaesthetic, when infiltrated in the wound at the end of operation of THA.

High volume infiltration with local anaesthetics (LIA) during total knee arthroplasty (TKA) for postoperative pain relief may be beneficial as compared to traditional methods. Retransfusion drains are used in TKA as alternative for allogeneic blood transfusions. When combining both modalities, recollected blood may contain large doses of local anaesthetics potentially leading to systemic toxicity during retransfusion. We investigated the safety of combining LIA and retransfusion of shed blood.

Twenty patients scheduled for primary TKA were included. During surgery two peri-articular injections with ropivacaine (total 375 mg) were given. Patients received an intraarticular retransfusion drain and a wound catheter for continuous infusion of ropivacaine (8 mg/hr) for 24 hours. Blood collected in the retransfusion device, was not retransfused but used for laboratory analyses. Patients’ blood samples were taken immediately after surgery, 3, 6 and 24 hours postoperatively. We predicted cumulative ropivacaine concentrations using patient and shed blood samples from 6 hours postoperatively. We modelled instant retransfusion by estimating the cumulative plasma concentrations. Our safety threshold was 0.15 mg/L unbound ropivacaine in a venous plasma sample, based on literature.

Total ropivacaine concentration was highest 24 hours postoperatively and unbound ropivacaine was maximal predominantly at 6 hours. Total ropivacaine concentrations ranged from 0.7 to 1.9 mg/L and unbound ropivacaine concentrations varied between 0.03 and 0.11 mg/L. At 6 hours median shed blood volume was 600 mL (range 303–869 mL). Interestingly was the difference (mean ± SD) in free fraction ropivacaine, in shed blood (68.8–4.6%) and in plasma (4.8 ± 1.1%).

Assuming retransfusion, an average 13 mg (range 6–18mg) of unbound ropivacaine would have been administered intravenously. The model used to estimate cumulative ropivacaine plasma levels showed that instant retransfusion potentially would have led to unbound venous plasma concentrations of above 0.15 mg/L.

Under the conditions in our study it is safe to use LIA in combination with continuous infusion of ropivacaine. However, in combination with the retransfusion of shed blood collected with the Bellovac ABT system this may lead to toxic levels. Before implementing the combination of both modalities formal testing is required.

Multimodal analgesia protocols for pain control following total joint arthroplasty can reduce post-operative pain, allow early mobilisation and early discharge from hospital. This study analyses the achievement of functional milestones, patient satisfaction, length of stay and adverse outcomes using a multimodal analgesia protocol in total joint arthroplasty. All patients planned for elective hip and knee arthroplasty in a NSW teaching hospital under one surgeon between July 2007 and January 2009 were included in this prospective study. Patients undergoing revision surgery, bilateral arthroplasty or total hip arthroplasty for fractures were excluded. Unless contraindicated, all patients followed the multimodal analgesia protocol based on the local infiltration analgesia technique described by Kerr and Kohan. Outcomes measurements included. Patient demographics, post operation milestones, visual analogue pain scores (VAS), narcotic consumption, length of stay, discharge destination, patient satisfaction scores and adverse outcomes. Nineteen patients (13 female and 6 male) with an average age 67 years and BMI 33 had total hip arthroplasty surgery. 84% (16/19) ambulated within six hours post operation. 47% (9/19) of patients were discharged home by day 3 post operation (1/19 on day 1, 5/19 on day 2, 3/19 on day 3). Average day post operation for discharge home was 4.5 days. Thirty-one patients (17 female and 14 male) with an average age 68 years and BMI 33 had total knee arthroplasty surgery. 90% (28/31) ambulated within six hours after surgery. 71% (22/31) of patients were discharged home by day three post operation (6/31 on day 1, 8/31 on day 2 and 8/31 on day 3). Average day post operation for discharge home was four days. Ten patients required morphine in addition to protocol analgesia. VAS scores (1 to 10) averaged 3.2 day one post op and 2.6 prior to discharge. Three patients developed nausea and vomiting and one patient developed urinary retention. No infections, DVTs or other adverse effects occurred in either hip or knee arthroplasty groups. Majority of patients were very satisfied according to 24 hour post op pain management survey and six week post op patient satisfaction survey. Local infiltration analgesia in knee and hip arthroplasty surgery is a safe, well-tolerated and effective form of pain control allowing early mobilisation and early discharge from hospital (1,2). This protocol has been successfully implemented in a public hospital

Aims

To investigate the impact of consecutive perioperative care transitions on in-hospital recovery of patients who had primary total knee arthroplasty (TKA) over an 11-year period.

Methods

This observational cohort study used electronic health record data from all patients undergoing preoperative screening for primary TKA at a Northern Netherlands hospital between 2009 and 2020. In this timeframe, three perioperative care transitions were divided into four periods: Baseline care (Joint Care, n = 171; May 2009 to August 2010), Function-tailored (n = 404; September 2010 to October 2013), Fast-track (n = 721; November 2013 to May 2018), and Prehabilitation (n = 601; June 2018 to December 2020). In-hospital recovery was measured using inpatient recovery of activities (IROA), length of stay (LOS), and discharge to preoperative living situation (PLS). Multivariable regression models were used to analyze the impact of each perioperative care transition on in-hospital recovery.

Background. Randomized, controlled trials (RCTs) are generally accepted as the “gold standard” for the provision of the most unbiased measures of the efficacy of interventions but are often criticized for the lack of external validity. We assessed the external validity of a RCT examining the efficacy of local infiltration analgesia (LIA) compared with continuous epidural infusion after total knee arthroplasty (TKA). Methods. During a one-year period, all patients consecutively admitted for elective, unilateral, primary TKA were identified as potential participants. All underwent eligibility screening to determine who were eligible for participation in a randomized controlled trial. We investigated the distribution of preoperative characteristics and postoperative variables among excluded patients, non-consenters, and enrolled and randomized participants. Results. In all 157 patients were identified as potential participants. Only 49 patients (31%) were enrolled and randomized. A significant difference was found in both preoperative characteristics and clinical outcome variables. Non-participants were less healthy and needed more help from the home care service than did participants. Furthermore, they were hospitalized longer. Interpretation. Our findings demonstrate the importance of reporting the results of RCTs in a way that allows clinicians to judge to whom the results can reasonably be applied

Objective. We have been using continuous epidural block and local infiltration cocktail for the pain management after TKA since 2005, and good pain control has been acquired with this method. During the past few years we have changed our protocol of postoperative pain management. We have stopped the administration of Loxoprofen starting next morning of the operation, instead Celecoxib was given starting before the operation. We have started mixing steroid to the intraoperative local infiltration cocktail to reduce acute pain as well as swelling. We also have stopped using suction drain, and delayed the timing of CPM start from day 2 to day 3. Methods. This is case control study, and 78 cases of unilateral TKA were investigated for the study. All cases were anesthetized with continuous epidural block with intravenous dosage of phentanyl and propofol. Compositions of local infiltration cocktail are 40ml 0.75% Ropivacaine, 60ml saline, 0.5ml epinephrin. Group1 (n=40) used this cocktail independently, and Group2 (n=38) used this cocktail with addition of 40mg of triamcinolone(Fig.1). Local infiltration cocktail was used during operation, which was injected to the whole joint capsule. In group1 Loxoprofen was given starting next morning, in group 2 Celecoxib was given starting at 7am on the day of operation. In group1 suction tube was left for 2 days, where as in group2 no suction tube was used postoperatively, and continuous epidural block catheter was removed on postoperative day 2 in both groups. CPM was started at postoperative day 2 in group 1 and postoperative day 3 in group 2. Numerical Rating Scale (NRS) was used to analyze the pain. Circumferences of knee and thigh, as well as ROM of knee joint were measured periodically. Results. Preoperative demographics showed no statistical difference between two groups(Fig. 2). Group 2 showed significantly less pain at 6am next morning postoperatively (Fig.3&4). Group 2 showed significantly lower NRS on motion at postoperative day1, 3, 5 and 7 (Fig.5). Group 2 also showed significantly less swellings of knees and thighs at postoperative day 7 (Fig.6). The ROM of the knee joints at postoperative day 7, 14 and 21 were better in group2(Fig.7). Discussions. Our new method of multimodal pain control is effective. It significantly decreased the pain at 6am next morning postoperatively, which is due to preoperative administration of Celecoxib. The pain on motion during 1 st week was significantly decreased which is probably due to the addition of steroid to the cocktail. Suction drain was not needed, if you use steroid in the cocktail and delay the timing to start CPM. The swelling was significantly reduced by steroid injection and delay in ROM exercise. As a result better ROM at postoperative day 7,14 and 21 were obtained. To view tables/figures, please contact authors directly

Background. Continuous epidural anesthesia or femoral nerve block has decreased postoperative pain after total knee arthroplasty to some extent. Although the established efficacy of these pain relief method, some adverse events such as hematoma or muscle weakness are still problematic. Intraoperative local infiltration of analgesia (LIA) has accepted as a promising pain control method after total knee arthroplasty. The safety and efficacy of LIA has been reported, although there are still limited evidence about the effect of LIA on quadriceps function and recovery of range of motion in early post-operative phase. The purpose of this study is to compare the quadriceps function and range of motion after TKA between the LIA with continuous epidural anesthesia and continuous epidural anesthesia alone. Methods. Thirty patients with knee osteoarthritis who underwent primary TKA were included in this study. Patients who took anticoagulants were treated continuous epidural anesthesia alone (n=11) and the other patients were treated with LIA with continuous epidural anesthesia (n=19). A single surgeon at our department performed all surgeries. Surgical procedure and rehabilitation process was identical between two groups. Before the implantation, analgesic drugs consisting of 20 ml of 0.75 % ropivacaine and 6.6 mg of dexamethasone were injected into the peri-articular tissues. In each group, fentanyl continuous epidural patient-controlled analgesia (PCA) was also used during 48-h post-operative period. Knee flexion and extension angle were evaluated before surgery, post-op day 3, 7, 10 and 14. The quadriceps function was evaluated by quadriceps peak torque at 30° and 60° flexion using VIODEX. The peak torque was recorded preoperatively, day 14 and 3 month after surgery. The difference between two groups was analyzed by Mann Whitney U-test using Prism 6, a statistical software. Results. LIA group showed better postoperative flexion angle until day 7 (Fig. 1). Then the discrepancy became smaller and came to the same degree at day14. The peak torque at 30° and 60° flex is higher in LIA group compared to epidural anesthesia alone. The LIA group showed less peak torque decrease at 2 weeks after surgery than epidural anesthesia alone group (Fig. 2, 3). No adverse events such as were observed in each group. Discussion. This paper demonstrated that LIA in addition to the continuous epidural anesthesia after TKA provides better quadriceps function and early recovery in knee range of motion. In this study we also used continuous epidural anesthesia, thus this study can not evaluate the stand alone LIA effects on quadriceps function and range of motion recovery. Furthermore the patients were not randomly assigned in this study, this might be another limitation of this study. In conclusion, LIA provide better quadriceps function and early recovery of range of motion in addition to the pain relief. To view tables/figures, please contact authors directly

Aims

This study compared patient-reported outcomes of three total knee arthroplasty (TKA) designs from one manufacturer: one cruciate-retaining (CR) design, and two cruciate-sacrificing designs, anterior-stabilized (AS) and posterior-stabilized (PS).

Methods

Patients scheduled for primary TKA were included in a single-centre, prospective, three-armed, blinded randomized trial (n = 216; 72 per group). After intraoperative confirmation of posterior cruciate ligament (PCL) integrity, patients were randomly allocated to receive a CR, AS, or PS design from the same TKA system. Insertion of an AS or PS design required PCL resection. The primary outcome was the mean score of all five subscales of the Knee injury and Osteoarthritis Outcome Score (KOOS) at two-year follow-up. Secondary outcomes included all KOOS subscales, Oxford Knee Score, EuroQol five-dimension health questionnaire, EuroQol visual analogue scale, range of motion (ROM), and willingness to undergo the operation again. Patient satisfaction was also assessed.

Fast-track THA and TKA is a dynamic process combining clinical and logistical enhancements to ensure the best outcome for all patients regarding faster early functional recovery and reduced morbidity. Focus is on reducing convalescence by ensuring a smooth pathway with the best available clinical treatment from admission to discharge – and beyond. Main focus areas include pain treatment, mobilization, organizational aspects, traditions, and care principles. Outcome is typically evaluated as: a) length of stay in hospital (LOS), patient satisfaction, and reduced convalescence in the form of earlier achievement of functional milestones; b) safety aspects (reduced morbidity and mortality in the form of complications and readmissions in general and dislocations/manipulations in specific); c) feasibility (can the track be applied to other subgroups of patients, i.e. bilaterals or revisions?); and d) economic savings. Favorable outcomes regarding all these parameters have been documented for fast-track THA and TKA which has also resulted in the development of a Rapid Recovery Programme (Biomet). LOS is now 1–2 days for unselected patients in leading departments with few readmissions, high patient satisfaction and economic savings. In Denmark, the nationwide median LOS is now 4 days and improved logistic features include homogeneous entities, regular staff, high level of continuity, preoperative information including intended LOS, admission on the day of surgery and functional discharge criteria. The improved clinical features include both intraoperative (spinal anesthesia, local infiltration analgesia (LIA), plans for fluid therapy, small standard incisions, no drains, compression bandages and cooling) and postoperative (deep venous thrombosis prophylaxis starting 6–8 hours postoperatively, multimodal opioid-sparing analgesia, early mobilization and discharge when functional criteria are met) facilitating early rehabilitation and discharge. Future challenges include identification of high-pain responders to improve multimodal pain treatment; identification of high-risk patients regarding complications in fast-track set-ups; how to reduce postoperative cognitive dysfunction; how to reduce orthostatic intolerance; and when how and to whom to initiate and give rehabilitation

Aims

Adenosine, lidocaine, and Mg2+ (ALM) therapy exerts differential immuno-inflammatory responses in males and females early after anterior cruciate ligament (ACL) reconstruction (ACLR). Our aim was to investigate sex-specific effects of ALM therapy on joint tissue repair and recovery 28 days after surgery.

Methods

Male (n = 21) and female (n = 21) adult Sprague-Dawley rats were randomly divided into ALM or Saline control treatment groups. Three days after ACL rupture, animals underwent ACLR. An ALM or saline intravenous infusion was commenced prior to skin incision, and continued for one hour. An intra-articular bolus of ALM or saline was also administered prior to skin closure. Animals were monitored to 28 days, and joint function, pain, inflammatory markers, histopathology, and tissue repair markers were assessed.

Aims

The primary objective of this study was to compare migration of the cemented ATTUNE fixed bearing cruciate retaining tibial component with the cemented Press-Fit Condylar (PFC)-sigma fixed bearing cruciate retaining tibial component. The secondary objectives included comparing clinical and radiological outcomes and Patient Reported Outcome Measures (PROMs).

Methods

A single blinded randomized, non-inferiority study was conducted including 74 patients. Radiostereometry examinations were made after weight bearing, but before hospital discharge, and at three, six, 12, and 24 months postoperatively. PROMS were collected preoperatively and at three, six, 12, and 24 months postoperatively. Radiographs for measuring radiolucencies were collected at two weeks and two years postoperatively.

Total knee arthroplasty (TKA) is a major orthopaedic intervention. The length of a patient's stay has been progressively reduced with the introduction of enhanced recovery protocols: day-case surgery has become the ultimate challenge.

This narrative review shows the potential limitations of day-case TKA. These constraints may be social, linked to patient’s comorbidities, or due to surgery-related adverse events (e.g. pain, post-operative nausea and vomiting, etc.).

Using patient stratification, tailored surgical techniques and multimodal opioid-sparing analgesia, day-case TKA might be achievable in a limited group of patients. The younger, male patient without comorbidities and with an excellent social network around him might be a candidate.

Demographic changes, effective recovery programmes and less invasive surgical techniques such as unicondylar knee arthroplasty, may increase the size of the group of potential day-case patients.

The cost reduction achieved by day-case TKA needs to be balanced against any increase in morbidity and mortality and the cost of advanced follow-up at a distance with new technology. These factors need to be evaluated before adopting this ultimate ‘fast-track’ approach.
