Total and partial joint arthroplasty has been clinically proven to successfully relieve pain and improve function in patients with hip and knee degenerative arthrosis. It has been shown that early return to ambulation correlates well with functional scores. Moreover, the benefits of reduced narcotic use are multi-fold and range from reduced risk of addiction, gastrointenstinal and cardiopulmonary side effects. Establishing realistic pre-operative expectations regarding functional improvement and pain control will nevertheless impact patient satisfaction. Thus, the purpose of this study was to establish safe, achievable and data-driven benchmarks for post-operative ambulation and pain control in patients undergoing elective total joint arthroplasty. A retrospective chart review was performed for of all patients who underwent elective primary total or partial joint replacement by a single fellowship trained academic joint replacement surgeon from 2/1/2015 to 2/29/16. Patients under the age of 18 as well as those who underwent arthroplasty to treat a traumatic injury or to revise an arthroplasty were excluded. Charts were reviewed for the method of ambulation (no ambulation, wheelchair, assistive devices, no devices) and use of prescription pain medications by 6 weeks post-operatively.Purpose

Ilizarov frame removal often occurs in the outpatient setting, and previous data has shown it can be a painful experience. Frames with a total of four or more olive wires or half-pins in combination yielded increased pain scores at frame removal. Sublingual fentanyl provides rapid onset, short acting analgesia for painful procedures such as dressing changes in burns patients. We hypothesised that administration of sublingual fentanyl, prior to frame removal would improve patients' pain scores. Twenty-one patients were given 100 mcg sublingual fentanyl prior to frame removal. Their pain scores were documented on an 11-point (0–10) numeric visual scale before, immediately after, 15 and 30 minutes after frame removal, and the following day. The same nurse specialist removed all the frames. Nitrous oxide was available for patients if they needed further analgesia. The majority of frames were removed from tibia. The average patient age was 40.8 years. Each frame had a median of 9 wires (range 2–17), and 4 olives (2–8). Eight frames had half pins (range 1–4, median 2). Fourteen patients used nitrous oxide in addition to fentanyl. Overall, the average pain score was 3.1. This peaked at 7.5 immediately after frame removal, but 15 minutes following removal the average was 2.5. Patients who had supplementary nitrous oxide had higher pain scores throughout (though not beforehand), although these differences were not statistically significant. Four patients (19%) reported adverse effects following administration, but none required medical intervention. Patients' pain scores averaged 2.52 within 15 minutes of removal, compared with 5.25 from our previous review. This suggests that fentanyl may be beneficial in frame removal, but our sample size was small, and more research is needed in this area.
The aim of our study was to assess the outcome of caudal epidural injection for patients with low back pain in relation to fatty infiltration of spinal muscle. This is a prospective study. The spinal muscles were graded on sagittal section T1 MRI at the lower border of lumber 4 vertebra from 3 to 12 depending on the severity of fatty infiltration. The outcome of the intervention was assessed by improvement in pre and post intervention oswestry disability index score as well as visual analog pain score. Patients with significant fatty changes don't respond well to the caudal epidural injection.
Acetabular revision surgery remains a technically demanding procedure with higher failure rates than primary total hip arthroplasty (THA). An acetabular component with three dimensional porous titanium and anatomic screw holes (Figure 1) was designed to allow the cup to be positioned anatomically and provide reliable fixation. A prospective multicenter study of 193 cases (190 patients) was conducted to assess the midterm clinical outcomes of the revision titanium acetabular shell. Radiographs, demographics, Harris Hip Score (HHS), and Short Form 36 (SF-36) were collected preoperatively, at 6 weeks, 3 months, and annually thereafter to 5 years. The mean duration of follow-up was 3.36 years. The Paprosky classification was assessed intraoperatively. Short Form 6D (SF-6D) utility values were obtained by transforming SF-36 scores through the Brazier method and were analyzed for effect size.Introduction

Abstract. Background. We know that tears of the Triangular fibrocartilage complex (TFCC) can cause DRUJ instability and ulnar sided wrist pain. This study shows the clinical result of patients who had arthroscopic transosseous repair of the TFCC tear with DRUJ instability. Arthroscopic repair of TFCC tear is a promising, minimally invasive surgical technique especially in patients with DRUJ instability. Materials and methods. Fifteen patients who underwent TFCC one tunnel repair form 2018–2021 were reviewed retrospectively in hospital. The proximal component of TFCC was repaired through arthroscopic one- tunnel transosseous suture technique. VAS score for pain, wrist range of motion, grip strength and post operative complications were evaluated and each patient was rated according to the DASH score. Results. The patients had a TFCC tear confirmed on MRI and was confirmed on arthroscopy by doing a hook test. The patients were followed up for 6 months. Twelve patients had normal stability of DRUJ and three patients showed mild laxity compared with the contralateral side. The mean VAS score reduced from 4.7 to 0.8 (P=0.001) and grip strength increased significantly. The quick DASH score (P=0.001)also showed significant functional improvement. No surgical related complications occurred. Conclusions. Arthroscopic one tunnel transosseous TFCC foveal repair can be an excellent and safe method for repair of TFCC tear with DRUJ instability. Its a good treatment option in terms of reliable
Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) with the flexor carpi radialis (FCR) tendon is one of the most common procedures for the treatment of thumb carpometacarpal (CMC) arthritis. An alternative method involves trapeziectomy alone (TA). The trapeziectomy with LRTI procedure was developed to theoretically improve biomechanical strength and hand function when compared to TA, which leaves an anatomical void proximal to the first metacarpal. The LRTI procedure takes longer to perform and includes an autologous tendon graft. The goal of this retrospective cohort study was to evaluate the clinical outcomes of trapeziectomy with or without LRTI at a minimum follow-up of 1 year. A total of 43 adult patients who had underwent a total of 58 (TA=36, LRTI=22) surgical procedures for CMC arthritis participated in the study. This single surgeon retrospective cohort study sampled patients who underwent CMC arthroplasty with either TA or LRTI techniques between 2008 and 2020 with a minimum time of 1 year post-operatively. The patients were evaluated subjectively (The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire) and objectively (hand/thumb strength, pre/post-operative hand radiographs). Both the TA and LRTI procedures provided good
Māori consistently have poorer health outcomes compared to non-Māori within Aotearoa. Numerous worldwide studies demonstrate that ethnic minorities receive less analgesia for acute pain management. We aimed to compare analgesic management of a common orthopaedic injury, tibial shaft fracture, between Māori and non-Māori. A retrospective cohort study from January 1. st. , 2015, to December 31. st. 2020 inclusive. Eligible patients were 16–65 years old and had isolated closed tibial shaft fractures. 104 patients were included in the study, 48 Māori and 56 Non-Māori. Baseline demographics were similar between the 2 cohorts. The primary outcome measure was type of analgesia charted on the ward. Secondary outcome measures were pre-hospital medications given, pain scores on arrival to the emergency department (ED) and the ward, time to analgesia in ED and type of analgesia given in ED. Statistics were calculated using Fisher's exact test, Pearson's chi-squared test or Wilcoxson's rank sum test as appropriate. No statistically significant differences were found in opiates or synthetics charted to Māori vs Non-Māori (83% vs 89% and 77% vs 88% respectively), opiates given in ED, time to analgesia in ED or ED and ward arrival pain scores. Of statistical significance is that Māori were less likely to receive pre-hospital medication compared to Non-Māori (54% vs 80% respectively, p=0.004). Māori were significantly less likely to receive pre-hospital pain medication compared to Non-Māori. However no other statistically significant findings were found when comparing pain scores, time to analgesia or type of
Introduction. Methoxyflurane can cause hepatotoxicity and nephrotoxicity at anaesthetic doses but has excellent analgesic properties and no nephrotoxic effects in patients without preexisting disease. Approved for use in the UK and Ireland in 2015, it is currently being used in emergency departments for analgesia during fracture reduction. During the Covid emergency, with theatre access severely restricted and many patients unwilling to use inhaled Nitrous oxide, Penthrox had the potential to provide adequate
Introduction. Day stay surgery for anterior cruciate ligament (ACL) reconstructions is an increasingly common practice and has driven clinicians to come up with postoperative pain regimes that allow same day mobilisation and a safe and timely discharge. There is a paucity of literature surrounding the use of intraosseous (IO) ropivacaine used as a Bier's block to provide both intraoperative and postoperative analgesia in lower limb surgery. Methods. This patient blinded, pilot study randomised 15 patients undergoing ACL reconstruction to receive either IO ropivacaine 1.5 or 2.0 mg/kg; or 300 mg of ropivacaine as local infiltration (standard of care). Toxic plasma levels of ropivacaine have been defined in the literature and therefore the primary outcome for this study was arterial plasma concentration of ropivacaine as a means to determine its safety profile. Samples were taken via an arterial line at prespecified times after tourniquet deflation. Secondary outcomes that we were interested in included immediate postoperative pain scores using the visual analogue scale (VAS) and perioperative opioid equivalent consumption. Results. Participants had a mean age of 27.8 (SD 9.2) years and 87% (13/15) were male. All patients in the intervention group receiving IO ropivacaine had plasma concentrations well below the threshold for central nervous system (CNS) toxicity (0.60 µg/ml). The highest plasma concentration was achieved in the intervention group receiving 1.5 mg/kg dose of ropivacaine reaching 3.59 mg/ml. This would equate to 0.22 µg/ml of free plasma ropivacaine. There were no differences across the three groups regarding pain scores or perioperative opioid consumption. Conclusions. This study demonstrates that IO administration of 0.2% ropivacaine is both safe and effective in reducing perioperative pain in patients undergoing ACL reconstruction. There may be scope to increase the IO dose further or utilise other analgesics via the IO regional route to improve perioperative
Regional anaesthesia is integral to best practice analgesia for patients with neck of femur fractures (NOFFs). These patients are generally frail and are vulnerable to side effects of opioid analgesia. Femoral nerve block (FNB) or fascia-iliaca block (FIB) can reduce opioid requirement. Literature supports good efficacy for extra-capsular NOFFs however it is acknowledged to be suboptimal for intracapsular fractures. We present a novel technique, using point of care ultrasound guidance to perform hip ultrasound guided haematoma (HUSH) aspiration, and injection of local anaesthetic (block) for intracapsular NOFFs. This a case control series. A consecutive series of cognitively intact patients, with an isolated intra-capsular NOFF, received a HUSH block using 10mls of 0.75% Ropivicaine. Haematoma was aspirated and volume recorded. This was performed in addition to standard NOFF pathway analgesia that includes a FIB and multimodal analgesia including opioids. Visual Analogue Scale (VAS)pain scores at rest and on movement were recorded pre and post procedure as well as combined morphine equivalent units administered post HUSH block. The control arm was a retrospective group of similar patients who followed the routine care pathway including a FIB. VAS pain scores from observation charts and usage of morphine equivalent units were calculated. Ten patients consented to receive HUSH blocks and we included thirty-eight patients in our control series. The HUSH block group showed mean VAS pain score of 4.2/10 at rest and 8.6 on movement prior to block. In the time after the block, VAS pain scores reduced to 1.5 at rest (p=0.007) and 3.1 on movement (p=0.0001) with a mean total morphine equivalent use of 8.75mg. This is significantly different from the control group's mean VAS pain at rest score 6.9 (p=0.0001) and 24.1mg total morphine equivalent (p=0.07). HUSH Block in addition to fascia iliaca block appears to significantly better
Introduction. Peri-articular local anesthetic injections reduce post-operative pain in total knee arthroplasty and assist recovery. It is inconclusive whether intra-operative injection of peri-articular morphine is locally effective. The aim of this study is whether the addition of morphine to peri-articular injections in only unilateral knee improves post-operative pain, range of motion, swelling in patients with simultaneous bilateral total knee arthroplasty. Materials and Methods. A prospective single-center double-blinded randomized controlled trial was undertaken to assess the local efficacy of adding morphine to intra-operative, peri-articular anesthesia in simultaneous bilateral total knee arthroplasty. Twenty eight patients with 56 TKAs were randomly divided into 2 groups, unilateral TKA with intraoperative peri-articular injection with adding morphine and the other side TKA without adding morphine. The morphine group received an intraoperative, peri-articular injection of local anesthetic (Ropivacaine 150mg), epinephrine (50μg), ketoprofen (25mg) and methylpredonisolone sodium (20mg) plus 0.1mg/kg of morphine. The no-morphine group received the same amount of local anesthetic, epinephrine, ketoprofen and methylpredonisolone sodium without morphine. The operating surgeon, operating staff, patients, physiotherapists, ward nursing staff and data collectors remained blinded for the duration of study. All surgeries were performed by the same operating team. A standard medial parapatellar approach was used in all operations. Post-operative analgesia was standardized to all participants with celecoxib daily for 3 weeks. Primary outcomes included visual analog pain scores (VAS), ROM and swelling of the thigh. Secondary outcomes included WOMAC and adverse outcomes. Result. There were no significant differences between two groups for pre-operative ROM, pre-operative pain VAS or the circumference of the thigh. There were no statistically significant differences in primary and secondary outcomes between two groups (Figure 1, 2, 3). Discussion. Multiple studies have demonstrated the clinical efficacy of multimodal peri-articular injection of analgesics in TKA for
Significance. In spite of evidence that total knee replacement (TKR) surgery is effective, numerous studies have demonstrated that approximately 20 percent of patients who have undergone TKR surgery are not satisfied. This relatively high rate of patients who are not satisfied is the result of unmet patient expectations. The strongest predictor of dissatisfaction after TKR is unmet expectations (RR = 10.7, Bourne, Chesworth, et al, 2010). This is confirmed by Dunbar, Richardson, and Robertsson (2013): “Unmet expectation seems to be a major cause of unsatisfactory outcomes and satisfaction is most strongly correlated with

Arthrosis of the hip joint can be a significant source of pain and dysfunction. While hip replacement surgery has emerged as the gold standard for the treatment of end stage coxarthrosis, there are several non-arthroplasty management options that can help patients with mild and moderate hip arthritis. Therefore, the purpose of this paper is to review early prophylactic interventions that may help defer or avoid hip arthroplasty. Nonoperative management for the symptomatic hip involves minimizing joint inflammation and maximizing joint mobility through intra-articular joint injections and exercise therapy. While weight loss, activity modifications, and low impact exercises is generally recommended for patients with arthritis, the effects of these modalities on joint strength and mobility are highly variable. Intra-articular steroid injections tended to offer reliable short-term
Revision surgery for pelvic discontinuity in the presence of bone loss is challenging. The cup-cage reconstruction option has become popular for the management of pelvic discontinuity in the recent years. The aim of this study was to review the clinical, radiological and patient reported outcomes with the use of cup cage construct for pelvic discontinuity at our institution. Twenty-seven patients (27 cup-cage reconstructions) were identified at median 6-year (minimum 2 year, maximum 10 years) follow up. Eight were female patients. The median age was 77 years [mean 72, range 37–90, SD 13.6]. There were 5 deaths and 2 were lost to follow up. Two patients were converted to excision arthroplasty; one for infection and one for failure of the construct. A further 3 patients required revision for instability but the cup cage construct was not revised (2 revisions of cemented cups to a constrained cup and one revision of proximal modular component of the femoral prosthesis). Revision of the cup cage construct was not necessary in any of these cases. We noted excellent
Over the past fifteen years, the average length of stay for total knee arthroplasty (TKA) has gradually decreased from several days to overnight. The most logical and safest next step is outpatient arthroplasty. Through the era of so-called minimally invasive surgery, perhaps the most intriguing advancements are not related to the surgery itself, but instead the areas of rapid recovery techniques and perioperative protocols. Rapid recovery techniques and perioperative protocols have been refined to allow for same-day discharge with improved outcomes. As mentioned, the single most important outcome from the minimally invasive movement has been the multi-modal approach to pain management of patients undergoing arthroplasty. Along with blood loss management, using tranexamic acid and hypotensive anesthetic techniques, this multi-modal program is the most important variable in reducing or avoiding side-effects. In any arthroplasty procedure, side-effects that need to be addressed include the negative effects of narcotics and blood loss. Anesthetic techniques, utilizing local nerve blocks, such as the adductor canal block and sciatic blocks for knee arthroplasty augment intraoperative anesthesia and provide postoperative

Large osteochondral defects of the glenohumeral joint are difficult to treat in young, active patients. When initial non-operative treatment with physical therapy, non-steroidal anti-inflammatory medications, corticosteroid injections, and viscosupplementation fails, surgery may become an option for some patients. Traditional shoulder arthroplasty and hemiarthroplasty provide excellent function and
