Emerging evidence suggests preoperative opioid use may increase the risk of negative outcomes following orthopedic procedures. This systematic review evaluated the impact of preoperative opioid use in patients undergoing shoulder surgery with respect to preoperative clinical outcomes, postoperative complications, and postoperative dependence on opioids.

EMBASE, MEDLINE, CENTRAL, and CINAHL were searched from inception to April, 2021 for studies reporting preoperative opioid use and its effect on postoperative outcomes or opioid use. The search, data extraction and methodologic assessment were performed in duplicate for all included studies.

Twenty-one studies with a total of 257,301 patients were included in the final synthesis. Of which, 17 were level III evidence. Of those, 51.5% of the patients reported pre-operative opioid use. Fourteen studies (66.7%) reported a higher likelihood of opioid use at follow-up among those used opioids preoperatively compared to preoperative opioid-naïve patients. Eight studies (38.1%) showed lower functional measurements and range of motion in opioid group compared to the non-opioid group post-operatively.

Preoperative opioid use in patients undergoing shoulder surgeries is associated with lower functional scores and post-operative range of motion. Most concerning is preoperative opioid use may predict increased post-operative opioid requirements and potential for misuse in patients.

Brazilian jiu-jitsu (BJJ) is a grappling-based martial art which can lead to injuries both in training and in competitions. There is a paucity of data regarding injuries sustained while training in Brazilian jiu-jitsu both in competitive and non-competitive jiu-jitsu athletes. Our primary objective was to determine the prevalence of injuries sustained during jiu-jitsu training and competition. Our secondary objectives were to describe the types of injuries, and to determine which participant and injury characteristics are associated with desire to discontinue jiu-jitsu following injury, and characteristics are associated with requiring surgery for an injury.

We conducted a survey of all BJJ participants at one club in Hamilton Ontario. We developed a questionnaire using focus groups, key informants and the previous literature. The questionnaire included questions on demographics, injuries in competition and/or training, treatment received, and whether the participant considered discontinuing BJJ following injury. The primary analysis was descriptive. The secondary analysis consisted of unadjusted logistic regression analyses to evaluate the association between selected demographic and injury patterns and those who considered quitting jiu-jitsu as a result of their injuries as a dependent variable.

Seventy BJJ athletes participated in this study (response rate 85%). The majority of respondents were male (90%), over the age of 30 years (58.6%), and junior trainees (white belts [37.2%] or blue belts [42.9%]). Ninety one percent of participants were injured in training and 60% of competitive athletes were injured in competitions. Significantly more injuries were sustained overall (p < 0 .001) for each body region (p∼0.001) in training in comparison to competition. Two-thirds of injured participants required medical attention, with 15% requiring surgery. Participants requiring surgical treatment were six and a half times more likely to consider quitting compared to those requiring other treatments, including no treatment (OR: 6.50, 95% CI: 1.53–27.60). Participants required to take more than four months off training were five and a half times more likely to consider quitting compared to those who took less time off (OR: 5.48, 95% CI: 2.25–13.38).

We identified that nine out of ten jiu-jitsu practitioners surveyed suffered injury while in training and the most severe injuries for the majority of practitioners occurring during training. The most common injuries identified involved the fingers, neck, knee, and shoulder, with the majority of respondents seeking medical or surgical treatment or requiring physiotherapy or rehabilitation. Potential participants in BJJ should be informed regarding significant risk of injury and instructed regarding appropriate precautions and safety protocols. BJJ practitioners and instructors should be especially cognizant of safety during training, where the majority of injuries occur.

Total hip arthroplasty (THA) is one of the most successful and effective treatments for advanced hip osteoarthritis (OA). Over the last 5 years, Canada has seen a 17.8% increase in the number of hip replacements performed annually, and that number is expected to grow along with the aging Canadian population. However, the rise in THA surgery is associated with an increased number of patients at risk for the development of an infection involving the joint prosthesis and adjacent deep tissue – periprosthetic joint infections (PJI). Despite improved hygiene protocols and novel surgical strategies, PJI remains a serious complication. No previous population-based studies has investigated PJI risk factors using a time-to-event approach and none have focused exclusively on patients undergoing THA for primary hip OA. The purpose of this study is to determine risk factors for PJI after primary THA for OA using a large population-based database collected over 15 years. Our secondary objective is to determine the incidence of PJI, the time to PJI following primary THA, and if PJI rates have changed in the past 15 years.

We performed a population-based cohort study using linked administrative databases in Ontario, Canada in accordance with RECORD and STROBE guidelines. All primary total hip replacements performed for osteoarthritis in patients aged 55 or older between January 1st 2002 – December 31st 2016 in Ontario, Canada were identified. Periprosthetic joint infection as the cause for revision surgery was identified with the International Classification of Diseases, 10th Edition (ICD-10), Clinical Modification diagnosis code T84.53 in any component of the healthcare data set.

Data were obtained from the Institute for Clinical Evaluative Sciences (ICES).

Demographic data and outcomes are summarized using descriptive statistics. We used a Cox proportional hazards model to analyze the effect of surgical factors and patient factors on the risk of developing PJI. Surgical factors include the approach, use of bone graft, use of cement, and the year of surgery. Patient factors include sex, age at surgery, income quintile and rurality (community vs. urban). We compared the 1,2,5 and 10 year PJI rates for patients undergoing THA each year of our cohort with the Cochran-Armitage test. Less than 0.1% of data were missing from all fields except for rurality which was lacking 0.3% of data.

A total of 100,674 patients aged 55 or older received a primary total hip arthroplasty for osteoarthritis from 2002–2016. We identified 1034 cases of revision surgery for prosthetic joint infection for an overall PJI rate of 1.03%. When accounting for patients censored at final follow-up, the cumulative incidence for PJI is 1.44%. Our Cox proportional hazards model revealed that male sex, Type II diabetes mellitus, discharge to convalescent care, and having both hips replaced during one's lifetime were associated with increased risk of developing PJI following primary THA. Importantly, the time adjusted risk for PJI was equal for patients operated within the past 5 years, 6–10 years ago, or 11–15 years ago. The surgical approach, use of bone grafting or cement were not associated with increased risk of infection. PJI rates have not changed significantly over the past 15 years. One, two, five and ten-year PJI rates were similar for patients undergoing THA in all qualifying years.

Analysis of a population-based cohort of 100,674 patients has shown that the risk of developing PJI following primary THA has not changed over 15 years. The surgical approach, use of bone grafting or cement were not associated with increased risk of infection. Male sex, Type II diabetes Mellitus and discharge to a rehab facility are associated with increased risk of PJI. As the risk of PJI has not changed in 15 years, an appropriately powered trial is warranted to determine interventions that can improve infection rate after THA.

International literature reports a 30% lifetime prevalence of intimate partner violence (IPV, domestic abuse). Many of those affected have little interaction with healthcare. Since a third of abused patients sustain musculoskeletal injuries, the fracture clinic has potential for identifying victims of abuse. The aim was to identify the proportion of fracture clinic patients who had suffered IPV within the past year.

A prospective questionnaire study of patients in three UK adult fracture clinics was conducted. There were no gender/age exclusions and the target sample size was 278. This study had ethics approval and the questionnaire used is validated in this population.

Of 336 respondents, 46% were females with 63% aged over 40 (212/336). The total prevalence of IPV within the preceding 12 months was 9% (29/336). The lifetime prevalence of IPV amongst respondents was 20% (68/336). 38% of patients suffering from IPV had been physically abused by their partner (11/29 vs. 7% in controls, p<0.001). None of the patients were being seen for an injury related to abuse. Two thirds of respondents thought that staff should ask routinely about IPV (64% 216/336) but only 5% had been asked about abuse (18/336).

This is the first study in the UK investigating prevalence of IPV in orthopaedics. There is a high lifetime prevalence of abuse in fracture clinic patients. Patients are willing to disclose abuse within the fracture clinic setting and are supportive of staff asking about abuse. This presents an opportunity to identify those at risk in this vulnerable population.

Femoroacetabular impingement (FAI) is a common cause of hip pain in the young adult. Uncertainty regarding surgical indications, outcome assessment, management preferences and perceptions of the literature exist. We conducted a large international survey assessing the perceptions and demographics of orthopaedic surgeons regarding FAI.

A survey was developed using previous literature, focus groups and a sample-to-redundancy strategy. The survey contained forty-six questions and was emailed to national orthopaedic associations and orthopaedic sports medicine societies for member responses. Members were contacted on multiple occasions to increase response rates.

Nine hundred orthopaedic surgeons from twenty national and international organisations completed the survey. Surgeons responded across 6 continents, 58.2 % from developed nations with 35.4 % having sports fellowship training. North American and European surgeons reported significantly greater exposure to hip arthroscopy during residency and fellowships in comparison to international respondents (48.0% vs. 44.5% vs. 25.6% respectively; p<0.001). Surgeons performing a higher volume of FAI surgery (over 100 cases per year) were significantly more likely to have practiced for more than 20 years (OR 1.91; 95% CI 1.01 to 3.63), be practicing at an academic hospital (OR 2.25; 95% CI 1.22 to 4.15), and have formal arthroscopy training (OR 46.17; 95% CI 20.28 to 105.15). High volume surgeons were over two-fold more likely to practice in North America and Europe (OR 2.26; 95% CI: 1.08 to 4.72).

The exponential rise in the diagnosis and surgical management for FAI appears to be driven largely by experienced surgeons in developed nations. Our analysis suggests that although FAI management is early in the innovation cycle we are at a tipping point towards wider uptake and utilisation. The results of this survey will help guide further research and study.
