Introduction. With advances in mobile application, digital health is being increasingly used for remote and personalised care. Patient education, self-management and tele communication is a crucial factor in optimising outcomes. Aims. We explore the use of a smartphone app based orthopaedic care management system to deliver personalised surgical experience, monitor patient engagement and functional outcomes of patients undergoing knee arthroplasty. Results. Over a 12-month period, 124 patients listed for knee arthroplasty were offered access to the app. Average patient age was 65.4 years (range 49 to 86). 13(10.4%) patients were over 80 years. Compliance with app usage was 86.4%. Compliance with post-operative exercises increased following a message through the app. The mean Oxford knee score improved from a pre-op value of 17 to 35 at a mean follow-up of 6 months. Mean numeric rating scale pain score reduced from 7 pre-operatively to 3 at the latest follow-up. 58 patients (46.7%) used the communication feature on the app (text messages, photos, video consultations), reducing telephone calls and patient foot fall in the hospital. Patient satisfaction with the app was very high. Conclusion. We found the virtual care system to be effective in providing patient education, prehabilitation and post-operative rehabilitation along with being an effective channel of communication between patients and the hospital team. Patient satisfaction and compliance was very high

To determine the effect of Dexamethasone on post-operative pain management in patients undergoing Total Knee Arthroplasty in terms of numerical pain rating scale and total opoid consumption. This Randomized Controlled Trail (RCT) was conducted for 02 years (7th September 2015 to 6th September 2017). All patients undergoing primary Unilateral Total Knee Replacement (TKR) for Osteoarthritis knee were included in the study. Patients with poor glycemic control (HbA1c > 7.6), Hepatic/Renal failure, corticosteroids/ Immunosuppression drug usage in the last 06 months, known psychiatric illnesses were excluded from the study. All patients were operated by consultant Orthopaedic surgeon under Spinal Anaesthesia and tourniquet control using medial para-patellar approach. Patients were randomly divided into 02 groups, A and B. 79 patients were placed in each group. Group A given 0.1mg/kg body weight Dexamethasone Intravenously 15 minutes prior to surgery and another dose 24 hours post-operatively while in group B (control group) no Dexamethasone given. Post-operative pain using the numerical pain rating scale (NRS) and total narcotics consumed converted to morphine dose equivalent noted immediately post-op, 12-, 24- and 48-hours post-operatively. Data analysis done using SPSS version 23. A total of 158 patients were included in the study. Of the total, 98 (62.02%) were females and 60 (37.98%) males. Average BMI of patients 26.94 ±3.14 kg/m2. Patients in group A required less post-operative analgesics (p < 0 .01) and had a better numerical pain rating scale score (p < 0 .01) as compared to group B. Pain scores at 24- and 48-hours post-op were significantly less for Dexamethasone group (p < 0 .01). Use of Dexamethasone per- and post-operatively reduces the pain and amount of analgesics used in patients undergoing TKA. For any reader queries, please contact . drjunaidrmc@gmail.com

Introduction. Pain after trauma has received relatively little research attention compared with surgical techniques and functional outcomes, but is important to patients. We aimed to describe nerve dysfunction and pain characteristics using tibial fractures as a model. We hypothesized that early nerve dysfunction was associated with neuropathic and chronic pain. Materials and Methods. Adult patients with isolated open or closed tibial diaphyseal fractures were prospectively observed for 1-year in 5 Major Trauma Centres. Nerve dysfunction was assessed using Semmes-Weinstein monofilaments, acute pain with the visual numerical rating scale (VNRS), neuropathic pain with the doleur neuropathique-4 score and quality of life (QOL) using the EQ-5D score. Results. Of 77 included patients, twenty-six (33.8%) had Gustilo-Anderson grade II or worse injuries. Forty-six (63.0%) had operative repair; 0 operation notes reported nerve injury. Mean VNRS pain scores one week post-injury were 4.6/10 (SD 2.4). Seventeen patients (23.3%) presented with impaired sensation, persisting in 11 (15.1%) at 3-months. Neuropathic pain affected 16 (20.8%) patients one week post-injury; a further 20 (26.0%) had >2 symptoms of nerve pain. Only four (11.1%) received anti-neuropathic drugs. At 6-months, twenty-three (31.5%) reported mobility problems, 21 (28.8%) difficulty completing normal activities, 25 (34.2%) pain and 15 (20.5%) anxiety and depression. Conclusions. Nerve dysfunction and neuropathic pain are common early features in patients with tibial fractures, but are poorly recognised and inadequately treated. Pain has long-term effects on patients’ QOL. Future work should aim to improve identification and management of neuropathic pain

INTRODUCTION. The benefits of combining enhanced recovery after surgery (ERAS) interventions with an outpatient THA/TKA program are uncertain. The primary objective was to compare adverse event rate and secondly to compare pain management, functional recovery, PROMs and patients' satisfaction. METHODS. We conducted an ambidirectional single subject cohort study on 48 consecutive patients who experienced both a standard-inpatient and an ERAS-outpatient THA/TKA (contralaterally). We compared complications according to Clavien-Dindo scale and Comprehensive Complications Index (CCI), and unplanned episodes of care. Postoperative pain assessed with a numeric rating scale, opioid consumption in morphine milligram equivalents, functional recovery, patient-reported outcome measures (WOMAC, KOOS, HOOS, Forgotten Joint Score and Patient Joint Perception) and patients' satisfaction were also evaluated. RESULTS. Following the ERAS-outpatient surgery, complication rates were reduced by more than 50% (2.1 vs 4.4, p<0.001), CCI was significantly lower (12.3 vs 19.1, p<0.001), and similar unplanned episodes of care were observed (p>0.999). In the first 8 postoperative hours, perceived pain was similar (p>0.805) while opioid consumption was significantly reduced with ERAS-outpatient care (9.3 vs 26.5 MME, p<0.001). Patients walked, climbed stairs, showered, performed activities of daily living, practised sports, went back to work sooner after ERAS-outpatient surgery (p<0.001), but PROMs were similar between groups at the last follow-up (p> 0.188). Patients were more satisfied with hospital stay, pain management, functional recovery, wound management, and overall experience of the ERAS-outpatient pathway and recommended it significantly more (p <0.002). DISCUSSION. Most studies comparing outpatient to inpatient programs conclude that outpatient surgeries did not increase complication or readmission rates, and, overall, were not inferior. We found that compared to std-inpatient practice, ERAS-outpatient program reduced complications by half while not resulting in more unplanned episodes of care. Moreover, it resulted in similar pain relief with fewer opioids, faster early functional recovery and higher satisfaction. Patients were significantly more inclined to recommend the ERAS-outpatient pathway after having personally experienced both outpatient and inpatient protocols. These finding are likely multifactorial and linked to the specific ERAS interventions. CONCLUSION. Results of this study highlight the importance of following ERAS principles when implementing an outpatient THA/TKA program

Proximal junctional kyphosis (PJK) is defined as adjacent segment kyphosis >10° between the upper instrumented vertebrae and the vertebrae 2 levels above following scoliosis surgery. There are few studies investigating the predictors and clinical sequelae involved with this relatively common complication. Our purpose was to determine the radiographic predictors of post-op PJK and to examine the association between PJK and pain/HRQOL following surgery for AIS. The Post-Operative Recovery after Scoliosis Correction: Home Experience (PORSCHE) study was a prospective multicenter cohort of AIS patients undergoing spinal fusion surgery. Pre-op and minimum 2 year f/u scoliosis and sagittal spinopelvic parameters (thoracic kyphosis–TK, lordosis–LL, pelvic tilt-PT, sacral slope-SS, pelvic incidence-PI) were measured and compared to numeric rating scale for pain (NRS) score, SRS-30 HRQOL and to the presence or absence of PJK (proximal junctional angle >100). Continuous and categorical variables were assessed using logistic regression and binomial variables were compared to binomial outcomes using chi-square. 163 (137 females) patients from 8 Canadian centers met inclusion criteria. At final f/u, PJK was present in 27 patients (17%). Pre-op means for PJK vs No PJK: Age 14.1 vs 14.7yr; females 85 vs 86%; scoliosis 57±22 vs 62±15deg; TK 28±18 vs 19±16deg ∗, LL 62±11 vs 60±12deg, PT 8±12 vs 10±10deg, SS 39±8 vs 41±9deg, PI 47±14 vs 52±13deg, SVA −9±30 vs −7±31mm. Final f/u for PJK vs No PJK: Scoliosis 20±11 vs 18±8deg, final TK 26±12 vs 19±10deg∗, LL 60±11 vs 57±12deg, PT 9±12 vs 12±13deg, SS 39±9 vs 41±9deg, PI 48±17 vs 52±14deg, SVA −23±26 vs −9±32mm∗. Significant findings: Pre-op kyphosis >40deg has an odds ratio (OR) of 4.41 (1.50–12.92) for developing PJK∗. The presence of PJK was not associated with any significant differences in NRS or SRS-30. ∗denotes p<0.05. This prospective multicenter cohort of AIS patients demonstrated a 17% risk of developing PJK. Pre-op thoracic kyphosis >40deg was associated with the development of PJK; however, the presence of PJK was not associated with increased pain or decreased HRQOL

The pain of arthritic disorders occurs in a social and environmental context. Thus, the pain of arthritis not only can affect the patient, but also the spouse. Numerous investigations have shown that the spouses of individuals with persistent pain report lower levels of marital satisfaction, higher rates of depression and lower quality of life. For the vast majority of patients with osteoarthritis, total hip (THA) or total knee (TKA) arthroplasty results in a significant reduction in pain, emotional distress, disability and a significant improvement in their quality of life and function. Little is currently known about how these recovery-related changes impact on the spouse or the marital relationship. Patients and their spouses were recruited within one-year following the arthroplasty surgery. Couples participated in a semi-structured interview and were each asked to recall their level of pain on a numerical rating scale from 1 to 10 before and after recovering from surgery, and provide a numerical rating score (10 points) for a set of seven questions pertaining to their level of disability in seven different activities of daily living. In addition, the spouses were asked to list in order of importance the ways in which the surgery of their spouse affected their overall quality of life. In total, 33 couples (66 respondents) answered the survey questionnaire. There were 17 male patients, 16 female patients who underwent 29 THAs and 4 TKAs. With regard to pain, the spouses estimated their partner's pain, both preoperatively and at the time of the survey, to be at a significantly higher level than the patient's perception (p=0.05). The spouses perceived a greater improvement in family/home responsibilities, recreation and social activities, and in their occupation than that noted by the partner. After the arthroplasty, the spouses indicated that their lives had improved with respect to doing more activities/leisure (70%), because there partner had less suffering (61%), they had more independence/less caregiving (54%), it improved their marital relationship (54%), they had a better social/family life (27%) and they were able to travel (27%). In addition to the patient, THA and TKA result in a significant improvement in quality of life and marital functioning of the spouse. This should not continue to be unrecognized as a significant benefit of the procedure

Introduction. Many minimally-invasive approaches have been described in an effort to improve short-term results of total hip arthroplasty (THA), aiming for fast recovery and prevention of dislocation. In our institution, we started to perform THA with SuperPATH approach, including preservation of soft tissue around the hip (James Chow et al. Musculoskelet Med 2011) since July 2014. The purpose of this study is to examine the short-term results of THA using SuperPATH, especially treatment progress of rehabilitation. Materials and methods. We performed a study of 30 patients (30 hips) with osteoarthritis of the hip joint who had a THA with SuperPATH approach. There were 4 men and 26 women with an average age of 71 years, which were followed up for 24 months. Patients were clinically assessed with Merle d'Aubigne score, postoperative hip pain during walking by Numerical Rating Scale (NRS:0–10), complications and treatment progress of rehabilitation in regard to moving and activities of daily living. Implant alignment and stability were radiologically evaluated by annual X-ray and CT acquired two months after surgery. Results. Merle d'Aubigne score was 10.4 (pain:2.9, mobility:4.5 walking ability:3.0) preoperatively and 16.8(pain:5.9, mobility:5.9, walking ability:5.0) at the latest follow-up. NRS showed less than 3 points for more than 50% of the THA patients next day postoperatively. For more than 80%, NRS showed less than 1 point at 7 days after surgery, and most patients acquired the ability of level ground walking for 100 meters independently by 4 days postoperatively, climbing up and down stairs independently by 5 days and wearing/taking off their socks independently by 7 days. There were no dislocation and infection, but intraoperative proximal femoral fracture was found for two cases, which was managed to treat with additional circulating wire intraoperatively. From CT images averaged cup position found to be 39±5 degrees for inclination, and 21±6 degrees for anatomic anteversion, averaged stem anteversion to be 33±9 degrees. No loosening of components was evident. Discussion and Conclusion. Many minimally-invasive approaches have developed, there have been many reports on fast recovery and low incidence of postoperative hip dislocation, however, the risk of complications related to shortage of operative field has been pointed out. In this study, intraoperative proximal femoral fracture occurred for two cases, but the components position seemed excellent and NRS showed less pain postoperatively and most of the patients acquired walking ability in a few days. SuperPATH approach, including pass way from between the Gluteus Medius and the piriformis tendon, can preserve the whole short external rotators and capsule of the hip joint, leading to fast rehabilitation progress. Moreover, this approach may be friendly to the surgeons familiar with the posterior approach because of easily conversion to the conventional posterior approach

An outpatient TKA program was developed by integrating advances in analgesia, rehabilitation, and minimally invasive surgical techniques with the objective of improving value in elective total knee arthroplasty (TKA) while maintaining quality standards. Previous studies have established the safety of outpatient TKA in selected populations, but the literature is devoid of outcome measures in these patients. Our goal was to investigate the quality of recovery, patient satisfaction, and safety profile in the first 90 days undergoing outpatient TKA. One hundred TKAs in 93 consecutive patients with end-stage arthritis of the knee candidate for primary TKA were enrolled in this prospective matched cohort study. Patients that underwent inpatient TKA (47 TKAs) were compared with patients that underwent planned outpatient TKA (53 TKAs). The following 28 day post-operative scores were recorded: quality of recovery (QoR-18) and pain scores by Numerical Rating Scale (NRS-11). Satisfaction with pain control (0 to 10) and quantity of opioid use was collected. Secondary outcome measures of 90-day complications, readmissions, and emergency department (ED) visits were recorded. Ninety-six percent of patients planned for outpatient TKA met our defined multidisciplinary criteria for same-day discharge. QoR-18 at post-operative day one was statistically higher in the outpatient TKA group. Otherwise, outcome measures were not statistically different between the 2 groups. Two patients required overnight admission: 1 for extended motor-block and 1 for vasovagal syncope. There were 7 ED visits in the in the outpatient group and 4 in the inpatient group. One outpatient was admitted for irrigation and debridement with liner exchange for an acute infection 2 weeks post-operatively. One inpatient required manipulation under anesthesia at six weeks post-operatively. Outpatient TKA in selected patients produced a post-operative quality of recovery and patient satisfaction similar to that of inpatient TKA. Our results support that outpatient TKA is a safe alternative that should be considered due to its potential cost-savings and comparable recovery

Introduction:. Rehabilitation after total knee arthroplasty (TKA) is an essential component of treatment. Various protocols and methodologies have evolved to enhance the effect of rehabilitation in the postoperative period. We prospectively evaluated the effect of using an antigravity treadmill as an alternative to routine postoperative physical therapy. Methods:. Twenty-nine patients undergoing unilateral primary TKA were randomized to either gait training (standard outpatient physical therapy) or to the use of an AlterG® antigravity device for gait training for 2 days/week for 4 weeks for a total of 8 therapy sessions. Average age was 68 and 55% were female. The Knee Injury and Osteoarthritis Outcome Score (KOOS) and Timed Up and Go (TUG) test were collected at baseline (first therapy session), at final therapy session and at 3 months postoperatively. The numerical rating scale (NRS) for pain was measured at baseline and at end of therapy. Adverse events and complications were recorded. Results:. All patients completed standard therapy and antigravity treadmill protocol without adverse events. KOOS, TUG and NRS scores improved in both groups but no statistically significant difference was apparent between groups. Overall, the greatest improvement was seen in the Sports/Recreation and Quality of Life subscales of the KOOS; scores improved from 23 and 32 to 67 and 69 at 3 months, respectively. TUG scores improved from 14 seconds to 7 seconds at 3 months. Pain, as measured on the NRS, improved from 2.8 to 1.1. Subjectively, therapists reported 100% satisfaction with the antigravity treadmill for use in postoperative TKA rehabilitation. Conclusion:. This initial study demonstrated that an antigravity treadmill device was safe and effective for outpatient postoperative TKA rehabilitation. Further studies are warranted to better define the role of this device as an alternative or adjunct to currently established TKA rehabilitation protocols

Background. Absence of rotator cuff allows unbalanced muscle forces of the shoulder to cause vertical migration of the humeral head. The translation of the humerus causes impaction of articular surface against the acromion. The purpose of the study is to assess outcome of Cuff tear arthropathy (CTA) Hemiarthroplasty prosthesis in this group of patients. Methods. Retrospective review was undertaken in 42 patients who underwent Global CTA Hemiarthroplasty between Jan 2001-Jan 2009. The mean length of follow up was 6 years. Results. The patients at review showed statistically significant improvement in Forward Flexion, Abduction and Numerical Pain Rating. There were four revision surgeries and the overall survival rate at ten years was 89 %. There was statistically significant improvement (p < 0.05) in forward flexion abduction and Numerical rating scale (p 0.02). Although improvement was noted in external and internal rotation this was not statistically significant. There was one perioperative humerus fracture which required plating at the same time of surgery. The fracture went on to heal uneventfully. There was also one post-operative haematoma which required arthroscopic washout. One patient underwent further arthroscopic debridement for poor ROM which improved from 20 Abd 20 FF to 90, 90 FF, Abd. There were four revision surgeries; 3 revisions to reverse geometry replacement; and one patient had removal of implant because of persistant dislocation of implant and patient did not want another major surgery. Patients who required revision had further erosion of acromion and poor ROM of < 20 Abd, FF, and Pain 8–10/10. Conclusion. This study shows that significant improvement in pain, and movements are achieved with this device. Acromial and glenoid erosion is a potential issue with this prosthesis and three revisions were required for this this problem. The results are better than standard hemiarthroplasty when used in this setting

Abstract. Displaced mid-shaft clavicle fractures have traditionally been treated non-operatively. New evidence supports the use of operative treatment with better functional results although with some risk of adverse complications. The patient's opinion in choosing one or the other option of treatment is important especially when a new therapeutic philosophy is introduced. We aimed to obtain the patients' preference based on their opinion of various possible outcomes of each treatment method. A clinical decision tree was constructed based on probabilities for various outcomes from the current literature. We used clinical decision analysis based on Bayesian logic. A similar clinical decision analysis was done for a cohort of orthopaedic surgeons. We interviewed 20 patients to obtain their health preferences on a numerical rating scale for each of the six possible outcomes for the conservative and operative treatments. Similar health preferences were obtained from 20 orthopaedic surgeons. The cohort of patients were young (age range: 13 – 21, mean: 16 years) males involved in active sport. The results of the decision analysis demonstrated a strong preference for operative management in this cohort of patients (combined probability of 0.81 for operative treatment versus 0.61 for non-operative). The cohort of orthopaedic surgeons were either career orthopaedic trainees or qualified orthopaedic surgeons with an age range of 28 – 41 years (mean age: 35 years). The results of the decision analysis demonstrated a weak preference for operative management in this cohort of surgeons (combined probability of 0.84 for operative treatment versus 0.77 for non-operative management). Overall the young active patient is eight times more likely to prefer operative treatment over non-operative management compared to the well informed orthopaedic surgeon. Patient education is the key to a better informed patient who can make a balanced decision. Clinical decision analysis can be a useful tool in this process

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

Introduction. Many prosthetic design changes have been introduced in attempt to improve outcomes following TKA; however there is no consensus as to whether these changes confer benefits to patients. This study aimed to assess whether patients treated with a modern implant design had an enhanced patient outcome compared to a traditional model in a double blind randomised controlled trial. Methods. 212 consecutive patients were prospectively randomised to receive either a modern (Triathlon) or a traditional (Kinemax) TKA (both Stryker Orthopaedics). 6 surgeons at a single unit performed all procedures in a standardised manner. A single researcher, blinded to implant allocation, performed all assessments. Patients were assessed pre-operatively, and at 6, 26, 52 weeks post-surgery with the Oxford Knee Score (OKS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, goniometry, timed functional assessment, lower limb power (Leg Extensor Power Rig) and pain numerical rating scales (NRS). Change in scores and between group differences were assessed with Two-Way Repeated Measures ANOVAs. Results. Both groups benefited from TKA demonstrating significant improvement in all parameters (p = < 0.001 in all cases). Significant interaction of the implant was observed in 1 year change score of OKS (F = 4.28, p = 0.04), knee flexion (F = 8.42, p = 0.004), lower limb power output (F = 11.33, p = 0.001) and maximal pain report (F = 7.44, p = 0.001), the modern implant superior in each case. Larger change scores were observed in WOMAC and timed functional assessments, but were not statistically significant. Conclusions. In a large prospective double blind randomised controlled trial, patients receiving a modern implant design demonstrated a significantly enhanced patient outcome in terms of knee range of motion, lower limb power output, reduced maximal pain report, and a clinically meaningful reduction in the OKS compared to a traditional design

To identify factors that predict poor patient-reported outcomes in patients with traumatic vertebral body fracture(s) of the thoracic and/or lumbar spine without neurological deficit. There is a paucity of information on factors that predict poor patient-reported outcomes in patients with traumatic vertebral body fracture(s) of the thoracic and/or lumbar spine without neurological deficit. Patients were identified from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). VOTOR includes all patients with orthopaedic trauma admitted to the two adult Level 1 trauma centres in Victoria, Australia. Patient-reported outcomes and data on possible predictive factors, including demographic details, injury-related and treatment-based factors, were obtained from the VOTOR database. Patient-reported outcomes were measured at 12 months post-injury using the 12-Item Short-Form Health Survey (SF-12), a Numerical Rating Scale (NRS) for pain, global outcome questions and data was collected on return to work or study. For the identification of predictive factors, univariate analyses of outcome vs. each predictor were carried out first, followed by logistic multiple regression. 344 patients were eligible for the study and data were obtained for 264 (76.7%) patients at 12 months follow-up. Patients reported ongoing pain at 12 months post-injury (moderate–severe: 33.5%), disability (70.1%) and inability to return to work or study (23.3%). A number of demographic, injury-related and treatment-based factors were identified as being predictive of poor patient-reported outcomes. Patients who had associated radius fracture(s) were more likely to have moderate to severe disability (odds ratio (OR) = 3.85, 95% confidence interval = 1.30–11.39), a poorer physical health status (OR = 3.73, 1.37–10.12) and moderate to severe pain (OR = 3.23, 1.22–8.56) at 12 months post-injury than patients without radius fracture. Patients who did not receive compensation for work-related or road traffic-related injuries were less likely to report moderate to severe pain (OR = 0.45, 0.23–0.90) or have a poorer mental health status (OR = 0.17, 0.04–0.70) at 12 months post-injury than those who received compensation. The prognostic factors identified in this study may assist clinicians in the identification of patients requiring more intensive follow-up or additional rehabilitation to ultimately improve patient care

In this study, we assessed implant survivorship, patient satisfaction, and patient-reported functional outcomes at two years for patients implanted with a customized, posterior stabilized knee replacement system. Methods. Ninety-three patients (100 knees) with the customized PS TKR were enrolled at two centers. Patients’ length of hospitalization and preoperative pain intensity were assessed. At a single time point follow-up, we assessed patient reported outcomes utilizing the KOOS Jr., satisfaction rates, implant survivorship, patients’ perception of their knee and their overall preference between the two knees, if they had their contralateral knee replaced with an off-the-shelf (OTS) implant. Results. At an average of 1.9-years implant survivorship was found to be 100%. From pre-op until time of follow-up, we observed an average decrease of 5.4 on the numeric pain rating scale. Satisfaction rate was found to be high with 90% of patients being satisfied or very satisfied and 88% of patients reporting a “natural” perception of their knee some or all the time. Patients with bilateral implants mostly (12/15) stated that they preferred their customized implant over the standard TKR. The evaluation of KOOS Jr. showed an average score of 90 at the time of the follow up. Conclusion. Based on our results, we believe that the customized PS implant provides patients with excellent outcomes post-surgery. Moreover, a subset of patients with an OTS implant in one knee and a customized PS implant in the other, we observed a trend in patients preferring the customized PS device over their OTS counterparts

Aims

Chronic osteomyelitis (COM) of the lower limb in adults can be surgically managed by either limb reconstruction or amputation. This scoping review aims to map the outcomes used in studies surgically managing COM in order to aid future development of a core outcome set.

Methods

A total of 11 databases were searched. A subset of studies published between 1 October 2020 and 1 January 2011 from a larger review mapping research on limb reconstruction and limb amputation for the management of lower limb COM were eligible. All outcomes were extracted and recorded verbatim. Outcomes were grouped and categorized as per the revised Williamson and Clarke taxonomy.

Aims

The aetiologies of common degenerative spine, hip, and knee pathologies are still not completely understood. Mechanical theories have suggested that those diseases are related to sagittal pelvic morphology and spinopelvic-femoral dynamics. The link between the most widely used parameter for sagittal pelvic morphology, pelvic incidence (PI), and the onset of degenerative lumbar, hip, and knee pathologies has not been studied in a large-scale setting.

Methods

A total of 421 patients from the Cohort Hip and Cohort Knee (CHECK) database, a population-based observational cohort, with hip and knee complaints < 6 months, aged between 45 and 65 years old, and with lateral lumbar, hip, and knee radiographs available, were included. Sagittal spinopelvic parameters and pathologies (spondylolisthesis and degenerative disc disease (DDD)) were measured at eight-year follow-up and characteristics of hip and knee osteoarthritis (OA) at baseline and eight-year follow-up. Epidemiology of the degenerative disorders and clinical outcome scores (hip and knee pain and Western Ontario and McMaster Universities Osteoarthritis Index) were compared between low PI (< 50°), normal PI (50° to 60°), and high PI (> 60°) using generalized estimating equations.

Aims

This study aims to enhance understanding of clinical and radiological consequences and involved mechanisms that led to corrosion of the Precice Stryde (Stryde) intramedullary lengthening nail in the post market surveillance era of the device. Between 2018 and 2021 more than 2,000 Stryde nails have been implanted worldwide. However, the outcome of treatment with the Stryde system is insufficiently reported.

Methods

This is a retrospective single-centre study analyzing outcome of 57 consecutive lengthening procedures performed with the Stryde nail at the authors’ institution from February 2019 until November 2020. Macro- and microscopic metallographic analysis of four retrieved nails was conducted. To investigate observed corrosion at telescoping junction, scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDX) were performed.

Introduction

Studies have addressed the issue of increasing prevalence of work-related musculoskeletal (MSK) pain among different occupations. However, contributing factors to MSK pain have not been fully investigated among orthopaedic surgeons. Thus, this study aimed to approximate the prevalence and predictors of MSK pain among Saudi orthopaedic surgeons working in Riyadh, Saudi Arabia.

Methods

A cross-sectional study using an electronic survey was conducted in Riyadh. The questionnaire was distributed through email among orthopaedic surgeons in Riyadh hospitals. Standardized Nordic questionnaires for the analysis of musculoskeletal symptoms were used. Descriptive measures for categorical and numerical variables were presented. Student’s t-test and Pearson’s χ2 test were used. The level of statistical significance was set at p ≤ 0.05.
