This paper presents an ongoing review of the use of a wedge-shaped porous metal augments in the shoulder to address glenoid retroversion as part of anatomical total shoulder arthroplasty (aTSA). Seventy-five shoulders in 66 patients (23 women and 43 men, aged 42 to 85 years) with Walch grade B2 or C glenoids underwent porous metal glenoid augment (PMGA) insertion as part of aTSA. Patients received either a 15º or 30º PMGA wedge (secured by screws to the native glenoid) to correct excessive glenoid retroversion before a standard glenoid component was implanted using bone cement. Neither patient-specific guides nor navigation were used. Patients were prospectively assessed using shoulder functional assessments (Oxford Shoulder Score [OSS], American Shoulder and Elbow Standardized Shoulder Assessment Form [ASES],
Hamstring grafts have been associated with reduced strength, donor site pain and muscle strains following Anterior Cruciate Ligament Reconstruction (ACLR). Traditional graft fixation methods required both semitendinosus and gracilis tendons to achieve a graft of sufficient length and diameter, but newer techniques allow for shorter, broad single tendon grafts. This study seeks to compare the outcomes between Single Tendon (ST) and Dual Tendon (DT) ACLR, given there is no prospective randomised controlled trial (RCT) in the literature comparing outcomes between these options. In this ongoing RCT: (ANZ Clinical Trials Registry ACTRN126200000927921) patients were recruited and randomised into either ST or DT groups. All anaesthetic and surgical techniques were uniform aside from graft technique and tibial fixation. 13 patients were excluded at surgery as their ST graft did not achieve a minimum 8mm diameter. 70 patients (34 ST, 36DT) have been assessed at 6 months, using PROMS including IKDC2000, Lysholm and Modified Cincinnati Knee,
Despite the current trend favoring surgical treatment of displaced intra-articular calcaneal fractures (DIACFs), studies have not been able to demonstrate superior functional outcomes when compared to non-operative treatment. These fractures are notoriously difficult to reduce. Studies investigating surgical fixation often lack information about the quality of reduction even though it may play an important role in the success of this procedure. We wanted to establish if, amongst surgically treated DIACF, an anatomic reduction led to improved functional outcomes at 12 months. From July 2011 to December 2020, at a level I trauma center, 84 patients with an isolated DIACF scheduled for surgical fixation with plate and screws using a lateral extensile approach were enrolled in this prospective cohort study and followed over a 12-month period. Post-operative computed tomography (CT) imaging of bilateral feet was obtained to assess surgical reduction using a combination of pre-determined parameters: Böhler's angle, calcaneal height, congruence and articular step-off of the posterior facet and calcaneocuboid (CC) joint. Reduction was judged anatomic when Böhler's angle and calcaneal height were within 20% of the contralateral foot while the posterior facet and CC joint had to be congruent with a step-off less than 2 mm. Several functional scores related to foot and ankle pathology were used to evaluate functional outcomes (American Orthopedic Foot and Ankle Score - AOFAS, Lower Extremity Functional Score - LEFS, Olerud and Molander Ankle Score - OMAS, Calcaneal Functional Scoring System - CFSS,

The trapeziometacarpal joint (TMCJ) is the most common hand joint affected by osteoarthritis (OA), and trapezium implant arthroplasty is a potential treatment for recalcitrant OA. This meta-analysis aimed to investigate the efficacy and safety of various trapezium implants as an interventional option for TMCJ OA. Web of Science, PubMed, Scopus, Google Scholar, and Cochrane library databases were searched for relevant studies up to May 2022. Preferred Reported Items for Systematic Review and Meta-Analysis guidelines were adhered to and registered on PROSPERO. The methodological quality was assessed by National Heart, Lung, and Blood Institute tools for observational studies and the Cochrane risk of bias tool. Subgroup analyses were performed on different replacement implants, the analysis was done via Open Meta-Analyst software and P values < 0.05 were considered statistically significant. A total of 123 studies comprising 5752 patients were included. Total joint replacement (TJR) implants demonstrate greater significant improvements in
Rotator cuff disease encompasses a spectrum from partial to full thickness tears. Despite being 2–3 times more common than full–thickness tears, effective non-operative treatment for partial thickness tears has remained elusive. Platelet enriched plasma (PRP) has been proposed to enhance rotator cuff healing by enhancing the natural healing cascade. However, its utility in rotator cuff disease remains controversial. The purpose of this study was to compare the patient reported outcomes between PRP and corticosteroid injection in patients with symptomatic partial thickness tears. This double blind randomized controlled trial enrolled patients with symptomatic, partial thickness rotator cuff tears or rotator cuff tendinopathy proven on ultrasound or MRI. Patients were randomized to either corticosteroid or PRP ultrasound-guided injection of the affected shoulder. Patients completed patient reported outcomes at 6 weeks and 12 weeks. The primary outcome was
Persistent post-surgical pain affects 10%-80% of individuals after common operations, and is more common among patients with psychological factors such as depression, anxiety, or catastrophising. We conducted a systematic review and meta-analysis of randomised, controlled trials to evaluate the efficacy of perioperative psychotherapy for persistent postsurgical pain and physical impairment. We searched Medline, PsycINFO, CINAHL, and the Cochrane Central Registry of Controlled Trials to identify relevant RCTs, in any language, from inception of each database to September 1, 2016. Paired independent reviewers identified studies, extracted data, and assessed risk of bias. We pooled treatment effects of perioperative psychotherapy on similar outcomes across eligible trials, focusing on intention-to-treat analysis. We used random effects models to perform all meta-analyses. The Grading of Recommendations, Assessment, Development and Evaluation system was used to assess the quality of evidence. Our search found 15 trials (2220 patients) that were eligible for review. For both persistent post-surgical pain and physical impairment, perioperative education was ineffective, while active psychotherapy suggested a benefit (test of interaction P=0.01 for both outcomes). Moderate quality evidence showed that active perioperative psychotherapy (cognitive-behaviour therapy, relaxation therapy, or both) significantly reduced persistent post-surgical pain [weighted mean difference (WMD) −1.06 cm on a 10 cm
Introduction. Postoperative nausea and vomiting (PONV) is a common occurrence following total joint arthroplasty, and can result in patient discomfort, delayed discharge, and decreased patient satisfaction. Carbohydrate loading as part of the Enhanced Recovery after Surgery (ERAS) protocol has gained popularity, and has been shown to minimize postoperative nausea, vomiting, pain, and lead to accelerated recovery and better overall outcome following abdominal surgery. This study aims to investigate the effects of preoperative carbohydrate-rich drinks on PONV following primary total knee arthroplasty (TKA). Methods. Patients undergoing primary TKA at one institution were enrolled randomly assigned to one of three groups: Group 1 received preoperative carbohydrate-rich drink, Group 2 received placebo water drink of similar appearance and taste, and Group 3 did not receive a drink (control). All healthcare personnel and patients (group 1 and 2) were blinded to group allocation. We compared rate of postoperative nausea, vomiting, length of stay (LOS), and opiate consumption (morphine equivalents, meq). We also reviewed
Introduction. In situ pinning for classic slipped capital femoral epiphysis(SLIP) is evolving to a more direct and anatomic realignment of proximal femoral epiphysis; but in no study the result of such a treatment in Valgus Slip, an uncommon type of slipped capital femoral epiphysis, has been reported. Material and methods. Three hips in three patients (one male, two female) with valgus SCFE were treated by sub-capital realignment (two hips) or femoral neck osteotomy (one hip) for anatomic realignment of proximal femoral epiphysis. Extended retinacular flap technique performed through surgical hip dislocation in all hips. They followed clinically by Merle d'Aubigne Scale and
Introduction. Primary robotic-arm assisted total hip arthroplasty (THA) yields more accurate and reproducible acetabular cup placement, nonetheless, data is scarce in terms of outcomes. The purpose of the present study was to report on patient-reported outcomes (PROMs) in a large group of patients who underwent robotic-arm assisted THA. The authors hypothesized that (1) patients who underwent robotic-arm assisted primary THA would achieve favorable and significant improvement in PROMs, (2) an accurate and reproducible acetabular cup placement with respect to the defined SafeZones would be obtained, and (3) a low rate of THA dislocation would be observed. Methods. Prospectively collected data were retrospectively reviewed between April 2012 to May 2017. Primary THA using Mako Robotic-Arm [Mako Surgical Corp. (Stryker), Fort Lauderdale, FL, USA] with minimum two-year follow-up for the Harris Hip Score (HHS) and the Forgotten Joint Score-12 (FJS-12) were included. Exclusion criteria were: bodymass index (BMI) > 40 kg/m2, age < 21-year old, worker's compensation, or unwilling to participate.
Background. Total ankle arthroplasty (TAA) with the use of third generation implants has demonstrated favorable clinical results and improved survival. However, few studies have compared the different types of implants. The purpose of this study was to perform a retrospective evaluation of patient outcomes and complications by comparing TAA procedures performed with HINTEGRA versus MOBILITY systems. Methods. Fifty-two consecutively enrolled patients (28 men and 24 women; mean age 64.8 years) underwent TAA using HINTEGRA (21 ankles) or MOBILITY (33 ankles) between September 2004 and July 2012.
Background. Robotic assistance is being increasingly utilised in the surgical field in an effort to minimise human error. In this study, we report minimum two-year outcomes and complications for robotic-assisted total hip arthroplasty. Methods. Data were prospectively collected and retrospectively reviewed between June 2011 and April 2014. Inclusion criteria were primary robotic-assisted THAs treating idiopathic osteoarthritis with ≥ 2- year follow-up. Demographics, operating time, complications, 2-year outcome scores and satisfaction, and subsequent surgeries were recorded. Results. There were 181 cases eligible for inclusion, of which 162 (89.5%) had minimum 2-year follow- up. Eighty-nine females and 73 males were included. Forty-seven cases used an anterior approach and 115 used posterior approach. Mean age was 61.2 and mean BMI was 29.8. At latest follow-up, mean
Introduction. This study sought to evaluate the patient experience and short-term clinical outcomes associated with the hospital stay of patients who underwent robotic arm-assisted total knee arthroplasty (TKA). These results were compared to a cohort of patients who underwent TKA without robotic assistance performed by the same surgeon. Methods. A cohort of consecutive patients undergoing primary TKA for the diagnosis of osteoarthritis by a single fellowship trained orthopaedic surgeon over a 39-month period was identified. Patients who underwent TKA during the year this surgeon transitioned his entire knee arthroplasty practice to robotic assistance were excluded to eliminate selection bias and control for the learning curve. A final population of 538 TKAs was identified. Of these, 314 underwent TKA without robotic assistance and 224 underwent robotic arm-assisted TKA. All patients received the same prosthesis and post-operative pain protocol. Patient demographic characteristics and short-term clinical data were analyzed. Results. Robotic arm-assisted TKA was associated with shorter length of stay (2.3 versus 2.6 days, p< 0.001), a 50% reduction in morphine milligram equivalent utilization (from 213 to 105, p< 0.001), decreased
Introduction. Patient-specific instrumentation (PSI) is a contemporary method to optimize accuracy of alignment in total knee arthroplasty (TKA). As the potential benefits come at the cost of increased economic and logistic expenses, there is great scientific and practical interest in the actual advantages and reliability of such systems. Therefore, the purpose of the present study was to compare clinical results, radiological limb alignment, and three-dimensional (3D)-component positioning between conventional instrumentation (CVI) and a computed tomographic (CT)-based PSI in primary TKA. Methods. Two-hundred-ninety consecutive patients (300 knees) with severe, debilitating osteoarthritis scheduled for TKA were included in this study using either CVI (n=150) or PSI (n=150). Patients were clinically assessed according to the Knee Society Score (KSS), range of motion (ROM), and
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,
Estimated to affect 2–5% of the population, adhesive capsulitis is a common cause of shoulder pain and dysfunction. The objective of this study is to determine if arthrographic injection of the shoulder joint with steroid, local anesthetic and contrast is an effective treatment modality for adhesive capsulitis and whether it is superior to arthrographic injection with local anesthetic and contrast alone. This is a double-blinded RCT of patients with a diagnosis of adhesive capsulitis who were randomly assigned to receive an image guided arthrographic glenohumeral injection with either triamcinalone (steroid), lidocaine (local anesthetic) and contrast or lidocaine and contrast alone. Outcome measures included active and passive shoulder range of motion (ROM) and functional outcomes assessed using the Shoulder Pain and Disability Index (SPADI), the Constant Score and a
To investigate clinical outcome scores in surgically treated patients with either spontaneous or postoperative pyogenic spondylodiscitis after 3, 12 and 24 month. 70 consecutive patients (mean age 64y; male n=33 female n=27) underwent surgical treatment due to pyogenic spondylodiscitis with or without epidural abscess at our department from 2011 to 2013. We performed either microsurgical debridement or debridement in combination with ventral support employing dorsally instrumented spondylodesis followed by bracing and antibiotic therapy up to 12 weeks. European life quality score (EQ-5D), Oswestry disability index (ODI) and

Regaining the walking ability is one of the main purposes of total knee arthroplasty (TKA). Improving the activities of daily living is a key of patient satisfaction after TKA. However, some patients do not gain enough improvement of ADL as they preoperatively expected, and thus are not satisfied with the surgery. The purpose of this study is to clarify the relationship between preoperative and postoperative physical functional status and whether preoperative scoring can predict the postoperative walking ability. Consecutive 136 patients who underwent total knee arthroplasty for osteoarthritis were prospectively assessed. The average age (±SD) was 74±7.7 and 74% of the patients was female. Berg Balance Scale (BBS) was assessed preoperatively and one year after the surgery. The time needed for 10m walking, muscle power for knee extension and flexion,
Introduction. There are conflicting reports about the efficacy of injection to the thumb carpometacarpal joint (CMCJ) for osteoarthritis (OA). The accuracy of joint injection without radiological control is unclear. We investigated the accuracy of blind injection and recorded their immediate and short term efficacy. Materials/Methods. We injected 25 consecutive patients between March 2010-January 2011. The CMCJ was palpated, manually distracted and a 23 gauze needle introduced blindly. Image intensifier was then used to visualize and redirect needle if necessary. Radio-opaque dye was injected to confirm intra-articular placement. We recorded patient demographics, number of attempts required for correct needle placement, pre and 10 minutes post-injection
