Year-round intensive, single-sport training beginning at an young age is an increasingly common trend in the youth athlete population. Early sport specialisation may be ineffective for long-term athletic success and contribute to an increased risk of physical injury and burn-out. The medical community has noted that repetitive movement patterns may occur in non-diversified activity and this may contribute to overuse injury in young athletes. Studies have begun to identify an association between early sport specialisation and lower extremity injuries in the youth athlete population that is independent of training volume. Recent literature has suggested that sport diversification, not specialisation, is a better path for athletic success and minimised lower extremity injury risk.

Background and Hypothesis Smoking is a well-established risk factor for tendon healing. The purpose of this study was to evaluate the differences in patient-reported outcome measures between smokers and nonsmokers who have undergone arthroscopic rotator cuff repair. It was hypothesized that smokers would have worse self-reported outcomes at 1 and 2 years postoperatively. Methods A total of 560 consecutive patients who underwent arthroscopic rotator cuff repair were divided into 2 groups: group I (smokers) n = 25 and group II (nonsmokers) n = 535. All participants were administered preoperative and postoperative surveys consisting of the following outcome-measuring tools: (i) visual analog scale, (ii) Veterans Rand 12-Item Health Survey, (iii) American Shoulder and Elbow Surgeons shoulder score, (iv) standard preoperative form consisting of 4 questions regarding their expectations of recovery, (v) Single Assessment Numeric Evaluation shoulder score, and (vi) Simple Shoulder Test. Results At 1 and 2 years postoperative, nonsmokers reported statistically significant differences in Veterans Rand 12-Item Health Survey mental scores (56.2 vs. 51.9, P = .0162 and 56.3 vs. 49.5, P = .0004, respectively). American Shoulder and Elbow Surgeons Shoulder scores showed no differences until the 2-year mark, at which time nonsmokers reported higher scores than smokers (87.9 vs. 79.0, P = .0212). Single Assessment Numeric Evaluation scores also remained similar up until 2-year follow-up, at which time nonsmokers reported statistically significant improvement (80.0 vs. 68.5, P = .0339). Nonsmokers reported higher Simple Shoulder Test scores at baseline and at 2-year follow-up (43.3 vs. 37.0, P = .0417 and 83.7 vs. 68.1, P = .0046, respectively). Conclusion At 2 years postoperatively, nonsmokers had significantly higher patient-reported outcome measure scores than smokers. In elective surgery, smoking status should be considered as a risk factor for poorer patient-reported outcomes after arthroscopic rotator cuff repair. However, smokers continue to report a clinical benefit at 2 years postoperatively.

Purpose To determine whether active smokers have different patient-reported outcomes relative to nonsmokers for pain, function, and overall health at baseline and 1 or 2 years after an arthroscopic partial meniscectomy. Methods Patients who underwent arthroscopic partial meniscectomy were identified. Demographic data, including smoking status and patient-reported outcome measures (PROMs), were prospectively collected preoperatively and 3 months, 6 months, 1 year, and 2 years postoperatively. Statistical analysis was performed using the mixed-effects model to compare PROMs preoperatively and 1 or 2 years postoperatively between nonsmokers and active smokers. Results 509 knees undergoing arthroscopic partial meniscectomy were divided into 2 cohorts: group I, nonsmokers (n = 470) and group II, active smokers (n = 39). There were statistically significant baseline differences in PROMs for nonsmokers versus smokers: visual analog scale (VAS), 5.0 ± 0.4 versus 6.3 ± 0.7, respectively (P = .001); Knee Injury and Osteoarthritis Outcome Score (KOOS) Pain scale, 50.3 ± 3.2 versus 42.5± 5.5 (P = .005); KOOS Symptoms scale, 50.0 ± 3.2 versus 43.6 ± 5.4 (P = .019); and Western Ontario and McMaster Universities Arthritis Index (WOMAC) Pain scale, 57.5 ± 3.4 versus 48.2 ± 6.1 (P = .003). There were also statistically significant differences in nonsmokers versus smokers regarding knee function at baseline shown by the KOOS Activites of Daily Living (ADL) scale: (61.1 ± 3.3 versus 53.5 ± 6.1; P = .015). Baseline mental health, as assessed by the Veterans Rand 12-Item Health Survey (VR-12) Mental Health questionnaire, was also statistically different between nonsmokers (55.4 ± 0.8) and smokers (51.5 ± 3.3; P = .020). Importantly, PROMs for pain and function were lower at all time points for smokers. Conclusion Patients who were active smokers at the time of partial meniscectomy had significantly worse baseline and postoperative PROMs compared with nonsmokers. Changes from baseline for smokers and nonsmokers were relatively consistent between groups 1 and 2 years postoperatively. Smokers will improve a relatively similar amount as nonsmokers after partial meniscectomy, but their overall PROM scores are lower. Level of Evidence III, retrospective comparative study.

Purpose To determine whether patients who are prescribed ibuprofen after arthroscopic rotator cuff repair have significantly different patient-reported outcomes for pain, function, and overall health at baseline and 1 and 2 years after operation relative to patients only prescribed opioids. Methods Patients who underwent a rotator cuff repair by a total of 3 surgeons and participated in the outcomes registry from 2012 to 2016 were screened for inclusion in this study. Inclusion criteria were primary arthroscopic rotator cuff repair, at least 2 years from the date of surgery and over the age of 18. Exclusion criteria were revision and open rotator cuff repair. All patients followed the standard postoperative rehabilitation protocol for rotator cuff repair. Patients were divided into 2 cohorts. Group I included patients who received ibuprofen/nonsteroidal anti-inflammatory agents (NSAID) after surgery (n = 281), and Group II consisted of patients who did not receive ibuprofen/NSAID after surgery (n = 182). Patient-reported outcome measures for Visual Analogue Scale, American Shoulder Elbow Surgeons score, Single Assessment Numeric Evaluation score, Simple Shoulder Test and The Veterans Rand 12-Item Health Survey were collected preoperatively and at 3 and 6 months, 1 year, and 2 years after surgery. Statistical analysis was performed to compare patient-reported outcome measures between Group I and II. Results This study consisted of 463 patients who underwent arthroscopic rotator cuff repair, and patients were divided into 2 cohorts. There were 281 patients who did not receive ibuprofen/NSAID after operation in Group I and 182 patients who did receive ibuprofen in Group II. There were no statistically significant differences between the 2 groups in age at treatment, mean body mass index, gender, ethnicity, diabetes, and number of rotator cuff tendons involved; however, there was a statistically significant difference in receiving worker’s compensation (P = .005), and this was subsequently adjusted for in our analysis. There were no significant differences in patient-reported outcomes for all metrics between the group prescribed ibuprofen and the group that was not prescribed ibuprofen at 1 and 2 years after surgery or in change from baseline. Conclusion Patients receiving ibuprofen did as well as patients who did not receive ibuprofen after arthroscopic rotator cuff repair on patient-reported outcome measures assessing shoulder pain, function, and overall health. Level of Evidence Level III, retrospective comparative study.

This chapter discusses the importance of neuromuscular training (NMT) programs consisting of both plyometric and strengthening exercises to maximize proximal muscle strength and decrease anterior cruciate ligament (ACL) injury rate in at-risk populations. Necessary components of a successful NMT program, such as target populations, frequency of training sessions, compliance, and feedback, are discussed. In order to prevent ACL injuries and future cases of osteoarthritis and total knee replacements, physicians, coaches, parents, and athletes should encourage implementation of ACL injury prevention programs in all athletes who are involved in sports with a high risk of ACL injury.

Introduction: The amount and duration of opioids necessary after anterior cruciate ligament reconstruction (ACLR) are inadequately defined. This study sought to prospectively (1) define the amount and duration of opioid consumption, (2) investigate the relationship between preoperative pain expectation and postoperative satisfaction with pain management, and (3) identify risk factors for increased opioid use after ACLR. Methods: One hundred eight patients undergoing primary ACLR with hamstring graft were prospectively analyzed for preoperative pain expectation, using visual analog scale (VAS) rating, and postoperative satisfaction with pain management. Univariate and multivariate analyses were done to identify patient characteristics associated with satisfaction and/or amount and duration of opioid use. Results: Mean duration and cumulative intake of opioid consumption after ACLR were 5.3 days and 15.3 tablets, respectively. Patients expected moderate postoperative pain: mean preoperative VAS = 68.9. The preoperative VAS rating was associated with a significantly greater amount (P = 0.0265) and longer duration (P = 0.0212) of opioid consumption. Baseline opioid users took opioids for twice as long postoperatively (10.0 versus 5.0 days; P = 0.0149) and consumed twice as many tablets (29.3 versus 14.8 tablets; P = 0.0280) compared with opioid-naive patients. Discussion: This study demonstrated on average 15.3 opioid tablets over 5.3 days provided satisfactory pain management after ACLR. Risk factors for increased opioid consumption included preoperative opioid use.

Objective: This study aimed to determine whether collegiate women's ice hockey players are receiving pre-season concussion education and evaluate the nature and delivery of this education. Secondarily, we aimed to assess whether players who recall receiving this education have greater knowledge about concussion or are more likely to have reported suspected concussions than their peers.Methods: An anonymous survey was completed by 459 NCAA women's ice hockey players. Players self-reported receipt of pre-season concussion education, year in school, division of competition, player position, and average length of ice hockey career. Players also completed scales assessing concussion knowledge, attitudes and prior reporting behavior for suspected concussions.Results: 65.3% of athletes affirmed that they received pre-season concussion education. Lecture by an athletic trainer was the most common modality. There were no differences in concussion knowledge or attitudes by concussion education status, NCAA division of competition, or year in school. Players with higher knowledge scores were more likely than their peers to have experienced a suspected concussion and to have not reported it (p = 0.056).Conclusions: Not all NCAA women's ice hockey players are receiving (or recall receiving) mandated concussion education from their institution. The inverse association between concussion knowledge and concussion reporting behavior, while not statistically significant, is concerning and warrants further study. More work is needed to develop educational materials about concussion that are acceptable and memorable to this population, and that help increase concussion care-seeking behaviors.

Purpose To evaluate the efficacy of nonopioid pain medication related to patient satisfaction with postoperative pain and identify potential risk factors for decreased patient satisfaction with nonopioid pain medications. Methods This was a prospective study conducted between January 2017 and April 2018 at a single institution. A power analysis was performed a priori, which determined an appropriate cohort size of 163 patients. Inclusion criteria were all patients older than age 18 who were undergoing a knee arthroscopy for a partial meniscectomy and/or chondroplasty. Patients were prescribed maximum-strength ibuprofen or acetaminophen and completed a preoperative and 2-week postoperative questionnaire to assess satisfaction with pain management. Results Among the 163 patients enrolled in the study, the average age was 48.7 years (range 21-73 years); 74 (45%) were male and 89 (55%) were female. Overall, 81.6% (95% confidence interval 75.7% to 87.5%, P Conclusions Based on the findings of this study, 82% of patients who undergo arthroscopic partial meniscectomy and/or chondroplasty can achieve satisfactory pain control with nonopioid pain management. Level of Evidence Prospective comparative study: Level II.

Sex plays a role in mediating different susceptibilities and outcomes of disease and injury. Sports injuries are included in this phenomenon, as recent research demonstrates that males and females show differences in incidences of varying injuries, presentations of injury, and treatment outcomes. Incidence of certain sports injuries like anterior cruciate ligament injury or patellofemoral pain syndrome may vary widely between male and female athletes, with female athletes being more susceptible to anterior cruciate ligament injury and patellofemoral pain syndrome. Treatment outcomes for males and females may also vary widely. For example, males have a higher risk of recurrent shoulder instability compared with females. These variances among incidence and outcome following certain injuries highlight the necessity of understanding these differences to provide quality care. It is especially important for the school nurse to be aware of these sex differences as they are well positioned to make youth athletes and their families aware of the varying injury susceptibilities among them.

ObjectivesRisk factors for anterior shoulder dislocation include young age, contact activities and male sex. The influence of sex on patient-reported outcomes of arthroscopic Bankart repair (ABR) is unclear, with few studies reporting potential differences. This study’s purpose was to compare patient-reported outcomes of males and females following ABR.MethodsProspectively collected data was analysed for 281 patients (males: 206, females: 75) after ABR with preoperative, 1-year and 2-year follow-up responses. The Wilcoxon signed-rank and χ2 tests, preoperative, 1 year and 2 year follow-up results were examined to determine differences of scores in males versus females.ResultsNo statistically significant sex differences were observed in Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES), Visual Analogue Scale (VAS) or Single Assessment Numerical Evaluation (SANE) Scores at 1-year or 2-year follow-up. Females had lower Veterans RAND 12-item health survey (VR-12) mental health subscores at 2-year follow-up (females: 52.3±9.0, males: 55.8±7.6, p=0.0016). Females were more likely to report that treatment had ‘exceeded expectations’ at 2-year follow-up regarding motion, strength, function and normal sports activities.ConclusionResults of study demonstrate that ABR has similar outcomes for both males and females. There were no statistically significant sex-related differences in SST, ASES, VAS or SANE scores following ABR. VR-12 mental health subscores showed a minimal difference at 2-year follow-up, with lower scores in females.Level of evidenceRetrospective cohort study; level II.

In the United States, there has been a steady increase in sports participation across all age groups. An estimated 27 million youths between the ages of 6 and 18 years participate in team sports, and 60 million participate in some form of organized athletics. While there are great benefits from sports participation, early single sport specialization carries an increased risk of overuse injuries and burnout. Specialization has become increasingly popular among parents and coaches due to the common belief that it is the best way to develop an elite athlete. However, for most sports, there is no evidence that specialization before puberty is necessary to achieve elite status and in fact, there is evidence to the contrary. A recent American Orthopaedic Society for Sports Medicine (AOSSM) consensus statement has highlighted the negative side effects of early sports specialization; these include increased risk for overuse injury and burnout. School nurses are well-positioned to affect this issue through providing education and raising awareness of the potential detrimental consequences associated with youth sport specialization.

The purpose of this study was to determine the efficacy of nonopioid pain management following arthroscopic partial meniscectomy and/or chondroplasty and to assess patients' attitudes regarding their need for opioid pain medication following these procedures. Patients who underwent a knee arthroscopy procedure for either partial meniscectomy and/or chondroplasty from July 2016 to January 2017 by a single surgeon at a single institution were included. Medical records were reviewed, and demographics were recorded. Two weeks postoperatively, patients self-reported opioid and nonopioid medication use. Patients were also questioned regarding their perceived need for opioid medication, whether they felt their pain was adequately controlled, and how their pain compared with their preoperative expectations. Thirty-four patients (17 male, 17 female), with a mean age at the time of surgery of 47.79 years (range, 19–68 years), were included. Eighty-two percent (n=28) of the patients reported using nonopioid analgesics for pain control, whereas 18% (n=6) reported using opioids. Of those not using opioids, 96.4% (n=27) reported not feeling the need for opioid medications. Three of 6 patients requiring opioids were unable to take nonsteroidal anti-inflammatory drugs. All 6 patients who took opioids felt that they needed them for adequate pain control. This study provides initial encouragement that it is largely possible to remove opioids from the postoperative pain regimen of knee arthroscopy patients and maintain adequate pain control and patient satisfaction.

Osteoarthritis (OA) is a leading cause of chronic disability whose mechanism of pathogenesis is largely elusive. Local inflammation is thought to play a key role in OA progression, especially in injury-associated OA. While multiple inflammatory cytokines are detected, the timing and extent of overall inflammatory activities in early OA and the manner by which joint inflammation correlates with cartilage structural damage are still unclear. We induced OA via destabilization of the medial meniscus (DMM) in NFκB luciferase reporter mice, whose bioluminescent signal reflects the activity of NFκB, a central mediator of inflammation. Bioluminescence imaging data showed that DMM and Sham control joints had a similar surge of inflammation at 1-week post-surgery, but the DMM joint exhibited a delay in resolution of inflammation in subsequent weeks. A similar trend was observed with synovitis, which we found to be mainly driven by synovial cell density and inflammatory infiltration rather than synovial lining thickness. Interestingly, an association between synovitis and collagen structural damage was observed in early OA. Using Second Harmonic Generation (SHG) imaging, we analyzed collagen fiber organization in articular cartilage. Zonal differences in collagen fiber thickness and organization were observed as soon as OA initiated after DMM surgery, which persisted over time. Even at 1 week-post surgery, the DMM joint showed a decrease in collagen fiber thickness in the deep zone and an increase in collagen fiber disorganization in the superficial zone. Since we were able detect and quantify collagen structural changes very early in OA development by SHG imaging, we concluded that SHG imaging is a highly sensitive tool to evaluate pathological changes in OA. In summary, this study uncovered a dynamic profile of inflammation and joint cartilage damage during OA initiation and development, providing novel insights into OA pathology.

Background: Rotator cuff repair is one of the most common surgical procedures performed on the shoulder. Previous studies have indicated that pain and disability can vary significantly between patients with similarly appearing rotator cuff tears on diagnostic imaging. Prior literature has compared functional outcomes between operative and nonoperative treatments as well as variability in surgical techniques. However, few studies have examined postoperative outcomes based on patient factors such as sex. Purpose: To compare patient-reported outcomes after rotator cuff repair between men and women. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 283 patients (153 male, 130 female) who underwent primary arthroscopic rotator cuff repair were included in this study; of those, 275 patients (97.2%) completed 1-year follow-up. Patient-reported pain visual analog scale (VAS), Veterans RAND 12-item Health Survey (VR-12 mental and physical components), American Shoulder and Elbow Surgeons (ASES), and Single Assessment Numeric Evaluation (SANE) scores were collected preoperatively and at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year postoperatively using an electronic outcomes system. Results: Women reported higher VAS pain scores when compared with men preoperatively ( P < .01) and at 2 weeks ( P < .01), 6 weeks ( P < .01), and 3 months ( P = .02) postoperatively. Additionally, women experienced a greater overall change in the mean VAS score preoperatively when compared with 1 year postoperatively ( P < .01). The use of narcotic pain medication 2 weeks after surgery was greater in women ( P = .032). Women had significantly lower preoperative VR-12 mental scores ( P = .03) and experienced a greater increase in the mean VR-12 mental score preoperatively when compared with 1 year postoperatively ( P < .01). Men had higher ASES scores preoperatively ( P < .01) and at 3 months postoperatively ( P < .01). Women experienced a greater overall change in the ASES score preoperatively when compared with 1 year postoperatively ( P < .01). Conclusion: Women reported greater pain and decreased shoulder function compared with men during the initial 3 months after arthroscopic rotator cuff repair. There were no sex-based differences in patient-reported outcomes at 1-year follow-up. The results of this study indicate that there are sex-related differences in the early postoperative recovery of patients undergoing rotator cuff repair, contributing to postoperative expectations for both clinicians and patients alike.

Purpose The purpose of this study was to evaluate the Brief Resilience Score (BRS) as a predictor for patient satisfaction with nonopioid pain management and patient-reported outcome measures (PROMs) after arthroscopic partial meniscectomy or chondroplasty. Methods One hundred seventy-five patients undergoing arthroscopic partial meniscectomy and/or chondroplasty were recruited from a single clinic and were preoperatively stratified into low-to-normal resilience or high resilience groups as measured by the BRS. Satisfaction with nonopioid pain control was assessed at a 2-week follow-up visit using the Hospital Consumer Assessment of Healthcare Provider and Systems questionnaire, and various PROMs were measured at 3 and 6 months postoperatively. Statistical analysis was performed to assess for differences in satisfaction with pain control or PROMs between resilience groups. Results Analysis revealed no statistically significant differences between the low-to-normal resilience group and the high resilience group with regard to satisfaction with nonopioid pain control or PROMs assessed at 3- or 6-month follow-ups. Outcome measures [visual analog scale pain, Knee Injury and Osteoarthritis Outcome Score (KOOS) Pain, KOOS Activities of Daily Living, KOOS Quality of Life, Single Assessment Numerical Evaluation (SANE) Knee, and Veterans Rand 12-Item Health Survey Physical and Mental Component Scores] all followed expected trajectories after surgery, without a statistically significant difference between resilience groups. Conclusion This study provides evidence that preoperative resilience score, as measured by the BRS, does not correlate with postoperative patient-reported functional outcome or satisfaction with a nonopioid pain regimen after knee arthroscopy. Level of Evidence II.

Several studies have identified graft diameter as a risk factor for failure following anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to evaluate the effect of graft diameter on patient reported outcome measures (PROMS) following ACLR. We performed a retrospective review of prospectively collected data using a global surgical registry. 153 of 287 patients (53.3%) had complete data for each timepoint. Effect of graft diameter, graft type, femoral tunnel drilling technique, patient age, sex, and body mass index were evaluated. At 1-year post-operatively, a 1-mm increase in graft diameter was found to correlate with a 5.7-point increase in the Knee Injury and Osteoarthritis Outcome Score (KOOS) activity of daily living score (p = 0.01), a 10.3-point increase in the sport score (p=0.003), and a 9.8-point increase in the quality of life score (p=0.013). At 2-years post-operatively, a 1-mm increase in graft size was found to be marginally correlated with KOOS symptoms and sport scores. Patients undergoing hamstring autograft ACLR, increasing graft diameter can result in improved PROMS, specifically improved KOOS subscale scores at 1 and 2-years post-operative.

Cryotherapy is the use of the anti-inflammatory and analgesic properties of ice to facilitate healing. Cryotherapy mediates these salutatory effects by reducing blood flow to the site of injury, down-regulating the production of inflammatory and pain-inducing prostaglandins, and diminishing the conductive ability of nerve endings. It is commonly used postoperatively in orthopedics to decrease analgesic requirements and blood loss as well as to increase range of motion, despite limited literature on its ability to produce such therapeutic effects in clinical practice. This article examines the available literature and the scientific evidence for the use and efficacy of cryotherapy in post-surgical orthopedic patients. It also reviews the potential pitfalls associated with improper use. Overall, this review seeks to provide insight into when, or whether, cryotherapy is appropriate for orthopedic patients during surgical recovery.

Background: Subacromial corticosteroid injections are frequently used for short-term pain relief in patients with subacromial impingement syndrome (SIS). However, the efficacy of corticosteroid injections is contested. The purpose of this study is to assess patient reported outcome measures (PROMs) and evaluate the duration of pain relief following a single subacromial corticosteroid injection to treat SIS. Methods: This prospective, single center cohort study enrolled 34 patients with a diagnosis of SIS. Participants received one subacromial corticosteroid injection in the affected shoulder and were evaluated at baseline, 2-week, 3- and 6-month post-injection. Results: Participants had statistically significant improvements at 3- and 6-month post injection in Visual Analogue Scale (VAS) pain, Western Ontario Rotator Cuff index (WORC), Shoulder Pain Disability Index (SPADI), and the 36-Item Short Form Survey (SF-36) subsections of pain, physical functioning, physical functioning role limiting, emotional role limiting and energy. Conclusions: Our study addresses some of the inconsistencies in the literature and supports the practice of administering subacromial corticosteroid injections for patients with SIS as patients demonstrated clinically significant improvements in VAS pain and other PROMs at both 3- and 6-month post-injection.
