Aims

Patient dissatisfaction following primary total knee arthroplasty (TKA) with manual jig-based instruments has been reported to be as high as 30%. Robotic-assisted total knee arthroplasty (RA-TKA) has been increasingly used in an effort to improve patient outcomes, however there is a paucity of literature examining patient satisfaction after RA-TKA. This study aims to identify the incidence of patients who were not satisfied following RA-TKA and to determine factors associated with higher levels of dissatisfaction.

Aims

People with severe, persistent low back pain (LBP) may be offered lumbar spine fusion surgery if they have had insufficient benefit from recommended non-surgical treatments. However, National Institute for Health and Care Excellence (NICE) 2016 guidelines recommended not offering spinal fusion surgery for adults with LBP, except as part of a randomized clinical trial. This survey aims to describe UK clinicians’ views about the suitability of patients for such a future trial, along with their views regarding equipoise for randomizing patients in a future clinical trial comparing lumbar spine fusion surgery to best conservative care (BCC; the FORENSIC-UK trial).

Aims

The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant.

Aims

The aim of this study was to report health-related quality of life (HRQoL) and joint-specific function in patients waiting for total hip or knee arthroplasty surgery (THA or TKA) in Northern Ireland, compared to published literature and a matched normal population. Secondary aims were to report emergency department (ED) and out-of-hours general practitioner (OOH GP) visits, new prescriptions of strong opioids, and new prescriptions of antidepressants while waiting.

Aims

The aim of this study was to determine the prevalence of depressive and anxiety disorders prior to total hip (THA) and total knee arthroplasty (TKA) and to assess their impact on the rates of any infection, revision, or reoperation.

There have been no studies assessing the acceptability of opioid tapering in the pre-arthroplasty setting. This qualitative study aimed to (1) explore barriers and facilitators to opioid tapering amongst patients with chronic non-cancer pain (CNCP), and (2) explore the similarities and differences in acceptability of opioid tapering between pre-arthroplasty patients and those participating in a biopsychosocial pain management program. From January 2021, adult participants diagnosed with CNCP and taking opioids daily (any dose at time of screening for a period of 3 months) were recruited from either Fairfield Orthopaedic Hip and Knee Service (FOHKS) or Liverpool Hospital Pain Clinic (LHPC). Semi-structured interviews underwent thematic analysis using the framework method. 17 participants were recruited (FOHKS, n=9, mean age 67, female 77%, LHPC, n=8, mean age 54, female 63%). Both groups had participants who; (i) were reluctant to use opioid medications and used them out of “necessity”, (ii) were reluctant to taper due to concerns of worsening pain, quality of life, (iii) believed opioids were “toxins” causing bodily harm. Some FOHKS participants believed tapering should be a post-operative focus, whilst others believed tapering opioids pre-operatively will assist in post-op pain management. Few LHPC participants felt dependent/addicted to opioids, thus driving their intention to taper opioids. The belief of tapering opioids causing worse pain was based on either previous experiences or concerns alone. Some FOHKS participants were more inclined to taper opioids if they were educated on the chronic and peri-operative risks associated with using opioids at time of arthroplasty. Opioid users recognise the harms associated with chronic opioid use and believe they are used out of desperation for adequate analgesia, function, and quality of life. Tapering opioids in the pre-arthroplasty context may need coupling with patient education highlighting the importance of opioid tapering pre-operatively

The risk of falls in patients undergoing orthopedic procedures is particularly significant in terms of health and socioeconomic effects. The literature analyzed closely this risk following procedures performed on the lower limb, but the implications following procedures on the upper limb remain to be investigated. Interestingly, it is not clear whether the increased risk of falling in patients undergoing shoulder surgery is due to preexisting risk factors at surgery or postoperative risk factors, such as anesthesiologic effects, opioid medications used for pain control, or brace use. Only one prospective study examined gait and fall risk in patients using a shoulder abduction brace (SAB) after shoulder surgery, revealing that the brace adversely affected gait kinematics with an increase in the risk of falls. The main purpose of the study was to investigate the influence of SAB on gait parameters in patients undergoing shoulder surgery. Patients undergoing elective shoulder surgery (arthroscopic rotator cuff repair, reverse total shoulder arthroplasty, and Latarjet procedure), who used a 15° SAB in the postoperative period, were included. Conversely, patients age > 65 years old, with impaired lower extremity function (e.g., fracture sequelae, dysmorphism, severe osteo-articular pathology), central and peripheral nervous system pathologies, and cardiac/respiratory/vascular insufficiency were excluded. Participants underwent kinematic analysis at four different assessment times: preoperative (T0), 24 hours after surgery (T1), 1 week after surgery (T2), and 1 week after SAB removal (T3). The tests used for kinematic assessment were the Timed Up and Go (TUG) and the 10-meter test (10MWT), both of which examine functional mobility. Agility and balance were assessed by a TUG test (transitions from sitting to standing and vice versa, walking phase, turn-around), while gait (test time, cadence, speed, and pelvic symmetry) was evaluated by the 10MWT. Gait and functional mobility parameters during 10MWT and TUG tests were assessed using the BTS G-Walk sensor (G-Sensor 2). One-way ANOVA for repeated measures was conducted to detect the effects of SAB on gait parameters and functional mobility over time. Statistical analysis was performed with IBM®SPSS statistics software version 23.0 (SPSS Inc., Chicago, IL, USA), with the significant level set at p<0.05. 83% of the participants had surgery on the right upper limb. A main effect of time for the time of execution (duration) (p=0.01, η2=0.148), speed (p<0.01, η2=0.136), cadence (p<0.01, η2=0.129) and propulsion-right (R) (p<0.05, η2=0.105) and left (L) (p<0.01, η2=0.155) in the 10MWT was found. In the 10MWT, the running time at T1 (9.6±1.6s) was found to be significantly longer than at T2 (9.1±1.3s, p<0.05) and at T3 (9.0±1.3s, p=0.02). Cadence at T1 (109.7±10.9steps/min) was significantly lower than at T2 (114.3 ±9.3steps/min, p<0.01) and T3 (114.3±9.3steps/min, p=0.02). Velocity at T1 (1.1±0.31m/s) was significantly lower than at T2 (1.2± 0.21m/s, p<0.05). No difference was found in the pelvis symmetry index. No significant differences were found during the TUG test except for the final rotation phase with T2 value significantly greater than T3 (1.6±0.4s vs 1.4±0.3s, p<0.05). No statistically significant differences were found between T0 and T2 and between T0 and T3 in any of the parameters analyzed. Propulsion-R was significantly higher at T3 than T1 (p<0.01), whereas propulsion-L was significantly lower at T1 than T0 (p<0.05) and significantly higher at T2 and T3 than T1 (p<0.01). Specifically, the final turning phase was significantly higher at T2 than T3 (p<0.01); no significant differences were found for the duration, sit to stand, mid-turning and stand to sit phases. The results demonstrated that the use of the abduction brace affects functional mobility 24 hours after shoulder surgery but no effects were reported at longer term observations

Aims

The aim of this study was to determine whether total hip arthroplasty (THA) for chronic hip pain due to unilateral primary osteoarthritis (OA) has a beneficial effect on cognitive performance.

Aims

Due to the opioid epidemic in the USA, our service progressively decreased the number of opioid tablets prescribed at discharge after primary hip (THA) and knee (TKA) arthroplasty. The goal of this study was to analyze the effect on total morphine milligram equivalents (MMEs) prescribed and post-discharge opioid repeat prescriptions.

Evidence suggests that the alleviation of pain is enhancedby a strong patient-clinician relationship and attending to a patient’s social and mental health. There is a limited role for medication, opioids in particular. Orthopaedic surgeons can use comprehensive biopsychosocial strategies to help people recover and can work with colleagues who have the appropriate expertise in order to maximize pain alleviation with optimal opioid stewardship. Preparing patients for elective surgery and caring for them after unplanned injury or surgery can benefit from planned and practiced strategies based in communication science.

Virtual encounters have experienced an exponential rise amid the current COVID-19 crisis. This abrupt change, seen in response to unprecedented medical and environmental challenges, has been forced upon the orthopaedic community. However, such changes to adopting virtual care and technology were already in the evolution forecast, albeit in an unpredictable timetable impeded by regulatory and financial barriers. This adoption is not meant to replace, but rather augment established, traditional models of care while ensuring patient/provider safety, especially during the pandemic. While our department, like those of other institutions, has performed virtual care for several years, it represented a small fraction of daily care. The pandemic required an accelerated and comprehensive approach to the new reality. Contemporary literature has already shown equivalent safety and patient satisfaction, as well as superior efficiency and reduced expenses with musculoskeletal virtual care (MSKVC) versus traditional models. Nevertheless, current literature detailing operational models of MSKVC is scarce. The current review describes our pre-pandemic MSKVC model and the shift to a MSKVC pandemic workflow that enumerates the conceptual workflow organization (patient triage, from timely care provision based on symptom acuity/severity to a continuum that includes future follow-up). Furthermore, specific setup requirements (both resource/personnel requirements such as hardware, software, and network connectivity requirements, and patient/provider characteristics respectively), and professional expectations are outlined. MSKVC has already become a pivotal element of musculoskeletal care, due to COVID-19, and these changes are confidently here to stay. Readiness to adapt and evolve will be required of individual musculoskeletal clinical teams as well as organizations, as established paradigms evolve.

Aims. Robotic-assisted total knee arthroplasty (RA-TKA) has been introduced to provide accurate bone cuts and help achieve the target knee alignment, along with symmetric gap balancing. The purpose of this study was to determine if any early clinical benefits could be realized following TKA using robotic-assisted technology. Methods. In all, 140 consecutive patients undergoing RA-TKA and 127 consecutive patients undergoing conventional TKA with minimum six-week follow-up were reviewed. Differences in visual analogue scores (VAS) for pain at rest and with activity, postoperative opiate usage, and length of stay (LOS) between the RA-TKA and conventional TKA groups were compared. Results. Patients undergoing RA-TKA had lower average VAS pain scores at rest (p = 0.001) and with activity (p = 0.03) at two weeks following the index procedure. At the six-week interval, the RA-TKA group had lower VAS pain scores with rest (p = 0.03) and with activity (p = 0.02), and required 3.2 mg less morphine equivalents per day relative to the conventional group (p < 0.001). At six weeks, a significantly greater number of patients in the RA-TKA group were free of opioid use compared to the conventional TKA group; 70.7% vs 57.0% (p = 0.02). Patients in the RA-TKA group had a shorter LOS; 1.9 days versus 2.3 days (p < 0.001), and also had a greater percentage of patient discharged on postoperative day one; 41.3% vs 20.5% (p < 0.001). Conclusion. Patients undergoing RA-TKA had lower pain levels at both rest and with activity, required less opioid medication, and had a shorter LOS

Aims

Unicompartmental knee arthroplasty (UKA) provides improved early functional outcomes and less postoperative morbidity and pain compared with total knee arthroplasty (TKA). Opioid prescribing has increased in the last two decades, and recently states in the USA have developed online Prescription Drug Monitoring Programs to prevent overprescribing of controlled substances. This study evaluates differences in opioid requirements between patients undergoing TKA and UKA.

Introduction. Regional anesthesia is commonly utilized to minimize postoperative pain, improve function, and allow earlier rehabilitation following Total Knee Arthroplasty (TKA). The adductor canal block (ACB) provides effective analgesia of the anterior knee. However, patients will often experience posterior pain not covered by the ACB requiring supplemental opioid medications. A technique involving infiltration of local anesthetic between the popliteal artery and capsule of knee (IPACK) targets the terminal branches of the sciatic nerve, providing an alternative for controlling posterior knee pain following TKA. Materials and Methods. IRB approval was obtained, a power analysis was performed, and all patients gave informed consent. Eligible patients were those scheduled for an elective unilateral, primary TKA, who were ≥ 18 years old, English speaking, American Society of Anesthesiologists physical status (ASA PS) classification I-III. Exclusion criteria included contraindication to regional anesthesia or peripheral nerve blocks, allergy to local anesthetics, allergy to nonsteroidal anti-inflammatory drugs (NSAIDs), chronic renal insufficiency with GFR < 60, chronic pain not related to the operative joint, chronic (> 3 month) opioid use, pre-existing peripheral neuropathy involving the operative limb, and body mass index (BMI) ≥ 40 kg/m. 2. . Patients were randomized into one of two treatment arms: Continuous ACB with IPACK (IPACK Group) block or Continuous ACB with sham subcutaneous saline injection (No IPACK Group). IPACK Group received single injection of 20 mL 0.25% Ropivacaine. Postoperatively, all patients received a standardized multimodal analgesic regimen. The study followed a double-blinded format. Only the anesthesiologist performing the block was aware of randomization status. Following surgery, a blinded medical assessor recorded cumulative opioid consumption, average and worst pain scores, and gait distance. Results. 72 people were enrolled in the study and three withdrew. There were 35 people in the IPACK group and 34 in the NO IPACK group. There was no difference demographically between the groups. In the Post Anesthesia Care Unit (PACU), the average (P=0.0122) and worst (P=0.0168) pain scores at rest were statistically lower in the IPACK group. There was no difference in the pain scores during physical therapy. (P=0.2080) There was no difference in opioid consumption in the PACU (P=0.7928), at 8 hours (P=0.2867), 16 hours (P=0.2387), 24 hours (P=0.7456), or 30 hours (P=0.8029). There was no difference in pain scores on POD 1 in the AM (P=0.4597) or PM (P=0.6273), nor was there any difference in walking distance (P=0.5197). There was also no difference in length of stay in the PACU (P=0.9426) or hospital (P=0.2141) between the two groups. Discussion/Conclusion. Overall, pain was well controlled between the two groups. The IPACK group had lower pain scores at rest in the PACU, but this may not be clinically significant. The routine use of the IPACK is not supported by the results of this study. There may be use of the IPACK block as a rescue block or in patients whom have contraindications to our standard multimodal treatment regimen, or in patients with chronic pain or opioid dependence

Introduction. Opioid abuse is a national epidemic. Traditional pain management after total knee arthroplasty (TKA) relied heavily on opioids. The evidence that in-hospital multimodal pain management (MMPM) is more effective than opioid-only analgesia is overwhelming. There has been little focus on post-discharge pain management. The purpose of this study was to determine whether MMPM after TKA could reduce opioid consumption in the 30-day period after hospital discharge. Methods. This was a prospective, two-arm, comparative study with a provider cross-over design. The first arm utilized a standard opioid-only (OO) prn regimen. The second arm utilized a 30-day MMPM regimen (standing doses of acetaminophen, metaxalone, meloxicam, gabapentin) and opioid medications prn. Surgeons crossed over protocols every four weeks. The primary outcome measure was VAS pain score. Secondary outcome measures included morphine milligram equivalents (MME) consumed, failure of the protocol, and manipulation under anesthesia (MUA). A pre-hoc power analysis was performed for the primary outcome measure and an intent-to-treat analysis was done utilizing a longitudinal mixed model. Results. There were 43 patients in the OO cohort and 39 patients in the MMPM cohort. There was no difference in the baseline demographics or preoperative scores (p=0.94). There was no clinically meaningful difference in VAS score between the two groups at any time. The average opioid consumption at 30-days was 469 and 344 MME's for the OO and MMPM cohorts, respectively (p=0.026). 19/43 (44.2%) patients in the OO cohort failed vs. 4/39 (10.3%) in the MMPM cohort (p=0.002). There was 1 MUA in the OO and none in the MMPM cohort (p=0.338). Discussion. A 30-day post-discharge multimodal pain regimen reduced opioid use after TKA. Opioid-only regimens are at an increased risk of failure to control pain. As a result of this study, multimodal pain management after hospital discharge is standard at our institution
