Performance and Return to Sport after Injury in Professional Mixed Martial Arts
Kingery, MatthewT; Kouk, Shalen; Anil, Utkarsh; McCafferty, Joseph; Lemos, Connor; Gelber, Jonathan; Gonzalez-Lomas, Guillem
BACKGROUND/UNASSIGNED:Mixed Martial Arts (MMA) is an increasingly popular combat sport incorporating striking and grappling that results in a high incidence of injuries. OBJECTIVES/UNASSIGNED:The purpose of this study was to analyze the impact of injuries on the return to sport and post-injury performance of professional MMA athletes. We hypothesize that increased age is associated with lower probability of return to sport and diminished post-injury performance. METHODS/UNASSIGNED:Publicly available data (obtained from ESPN.com/MMA, UFC.com, Rotowire.com/MMA) from professional MMA fighters who resigned from fight cards due to injury from 2012 to 2014 were analyzed. Injury history, match history and outcomes, and duration of time to return to professional fighting were recorded and compared to a cohort consisting of uninjured opponents. RESULTS/UNASSIGNED:454 fighters were included in the analysis. The mean age at the time of injury was 30.0+/-3.9 years. 94.4% of injured athletes were able to return to professional MMA, and athletes required a mean duration of 6.8+/-6.7 months between injury and their next professional fight (range 0.3-58 months). There was no significant difference in winning percentage in the post-injury period between the injured group and the uninjured group (p=0.691). Increased age at the time of injury was associated with the odds of being able to return to professional fighting after injury (OR=0.822, p=0.001). CONCLUSION/UNASSIGNED:In this analysis of publicly available injury data on MMA fighters, there was a high rate of return to professional sport and no evidence of an associated decline in performance following major injury requiring withdrawal from a fight card. Older age at the time of injury was associated with decreased odds of being able to return to professional fighting. With increasing popularity of combat sports, sport-specific prognostic information will help guide and treat specific injuries associated with MMA participation.

The Effect of Specialization and Level of Competition on Injury in Elite Male Ice Hockey Players
Ross, Keir Alexander; Fried, Jordan; Bloom, David A; Gonzalez-Lomas, Guillem
Objective: Young players experience pressure to focus on ice hockey at the exclusion of other sports in order to improve chances of success. Early specialization in other sports has been associated with increased injury without the benefit of improved success. The objective of the current study was to investigate whether earlier specialization results in increased injury without higher rates of career success. This study also aimed to compare rates of injury in athletes at various levels of competition.Methods: An original survey was issued to men's ice hockey players at the juniorA, collegiate, and professional levels. The survey consisted of 34 questions on various demographic, specialization, and injury variables. All participants were >18 years of age.Results: The survey was completed by 101 athletes. The mean age at specialization was 13 (±4) overall and 14 (±3), 13 (±4), and 11(±4) for professional, collegiate, and junior players, respectively. There was no difference in age at specialization between each group and professional players did not specialize earlier than the remainder of the cohort as a whole (p>0.05). There was no significant correlation between age at specialization and total injuries (p>0.05). There was no difference in concussions causing missed play time between groups (p>0.05) but professional players had more overall concussions and underwent more surgeries due to hockey related injuries (p=0.01).Conclusions: Specializing exclusively in ice hockey earlier in life was not associated with playing professionally. Both collegiate and professional players do not tend to specialize prior to age 12. Age at specialization was not associated with overall number of injuries. Professional players with longer careers appear to sustain more concussions and undergo more surgery.

Characterizing Sport Specialization Patterns in Professional Women's Ice Hockey Players
Bloom, David A; Wolfert, Adam; Whitney, Darryl; Gonzalez-Lomas, Guillem; Carter, Cordelia
BACKGROUND:Early year-round training in a single sport has been associated with high rates of overuse injuries. Despite this increasingly well-known risk of early sport specialization, many young athletes elect to specialize in a single sport due to the perception that this practice gives them the best chance of attaining elite athletic status. However, early specialization in women's ice hockey has not previously been shown to be reliably associated with attainment of elite levels of performance. We hypothesized that professional women's ice hockey players specialize in mid-adolescence, at an age comparable to their male counterparts. METHODS:An anonymous survey was given to members of two National Women's Hockey League teams. The athletes were asked how many years they have been playing hockey, at what age they began playing only hockey on a year-round basis, how many sports they played in addition to hockey, and if they felt that playing multiple sports while growing up positively affected their hockey careers. RESULTS:Fifty-four players completed the survey. The players reported playing hockey for an average of 19.4 ± 3.4 years. They began specializing in ice hockey at an average of 16.1 ± 3.3 years of age, 2 years later than previously reported in male NHL and NCAA athletes. Before specializing in hockey, players played an average of 3.5 ± 1.4 other sports. Ninetyone percent of players reported feeling as though playing other sports positively affected their hockey career.

Bone-Patellar Tendon-Bone Autograft Thickness Is a Risk Factor for Graft Failure. A Case-Control Analysis
Roach, Ryan; Anil, Utkarsh; Bloom, David A; Pham, Hien; Jazrawi, Laith; Alaia, Michael J; Gonzalez-Lomas, Guillem
BACKGROUND:Graft failure following anterior cruciate ligament reconstruction (ACLR) is a devastating complication. Risk factors such as patient characteristics and tunnel positions are well described. The relationship between graft dimension and failure rates has been investigated mainly in soft tissue grafts. Less studied are the effects of patella tendon (PT) dimensions on the risk of graft failure following patella tendon autograft (PTA) reconstructions. PURPOSE/OBJECTIVE:The purpose of the current study was to investigate if patellar tendon thickness measured on preoperative magnetic resonance imaging (MRI) predicts failure after ACLR using PTA. METHODS:This was an institutional review board approved, single-center, retrospective case-control study comparing patients' preoperative patellar tendon thickness between July 2005 and January 2017. Sixteen patients (mean age 21.2 ± 5.0 years) with PTA failure requiring revision surgery were identified and compared to 34 control patients who had undergone primary ACLR with PTA without failure with a minimum of 2-years follow-up. Patients with failure were matched at approximately 1:2 based on age, sex, height, weight, associated meniscus injury, and associated meniscal surgery. Patellar tendon dimensions were measured at the inferior pole of the patella (IPP), tibial tubercle insertion (TT), and longitudinal midpoint (MP) on preoperative axial and sagittal cut MRIs. Interclass correlation coefficeint (ICC) and Bland-Altman analyses were evaluated to determine inter-observer reliability. The two cohorts were compared using independent samples t-tests and analysis of variance. RESULTS:All ACLR failures occurred after a non-contact, pivot type injury. There were no significant differences in age, sex, height, weight, meniscal injury, or meniscal surgery between the two groups. Mean time between primary ACLR and revision was 2.6 ± 2.6 years and mean follow-up time was 3.1 ± 1.0 years in the control group. Patellar tendon length and width were not significantly different between the two groups. The average thickness at both the inferior pole and longitudinal midpoint was significantly higher in the failure group compared to controls (IPP: 5.04 ± 1.1 mm versus 4.33 ± 0.7 mm, p = 0.01; MP: 4.60 ± 0.7 mm versus 4.22 ± 0.5 mm, p = 0.03). Additionally, ICC was high across all measurements, with all values > 0.978. Similarly, all values demonstrated bias of less than ± 0.05. CONCLUSION/CONCLUSIONS:Patella tendon autograft anterior cruciate ligament reconstruction failures had significantly thicker patellar tendons at the inferior pole and longitudinal midpoint of the patella tendon.

Patient Satisfaction Is Equivalent Using Telemedicine Versus Office-Based Follow-up After Arthroscopic Meniscal Surgery: A Prospective, Randomized Controlled Trial
Herrero, Christina P; Bloom, David A; Lin, Charles C; Jazrawi, Laith M; Strauss, Eric J; Gonzalez-Lomas, Guillem; Alaia, Michael J; Campbell, Kirk A
BACKGROUND:Telemedicine has increasingly been considered as a viable alternative to traditional office-based health care, including postoperative follow-up visits. The purpose of the present study was to determine if patient satisfaction with overall care is equivalent for telemedicine follow-up (i.e., synchronous face-to-face video) and office-based follow-up after arthroscopic meniscectomy and repair. METHODS:Patients were prospectively enrolled from August 1, 2019, to March 1, 2020. Patients were included who were ≥18 years old, consented to isolated arthroscopic meniscal repair or meniscectomy, and were able to properly utilize telemedicine software on a computer, tablet, or smartphone with a built-in camera. Patient demographic data, including complication events and postoperative satisfaction data, were recorded and analyzed for significance. RESULTS:One hundred and fifty patients were enrolled in the study, of whom 122 (81.3%) were included in the final analysis. There were no significant differences between groups in terms of patient demographics or satisfaction scores. Patient satisfaction with overall care was equivalent based on the results of two 1-sided t-test analysis for equivalence (9.77 ± 0.60 in the office-based group versus 9.79 ± 0.53 in the telemedicine group; p < 0.001). When patients were asked to indicate their preferred follow-up type with the options listed as the type they received versus an alternative, 58 patients (84.1%) in the office-based group preferred their received type of follow-up, whereas 42 (79.2%) in the telemedicine group preferred their received follow-up (p = 0.493). There were no significant differences between groups in terms of complications (p > 0.05). CONCLUSIONS:The present study showed that patient satisfaction with overall care is equivalent between telemedicine and office-based follow-up in the immediate postoperative period following an arthroscopic meniscal surgical procedure, and should be considered a reasonable alternative to the traditional in-office modality.

Institutional Reductions in Opioid Prescribing Following Hip Arthroscopy Do Not Change Patient Satisfaction Scores
Bloom, David A; Manjunath, Amit K; Wang, Charles; Egol, Alexander J; Meislin, Robert J; Youm, Thomas; Gonzalez-Lomas, Guillem
Purpose/UNASSIGNED:To investigate what effect decreased opioid prescribing following hip arthroscopy had on Press-Ganey satisfaction survey scores. Methods/UNASSIGNED:A retrospective review of prospectively collected data was conducted on patients who underwent primary hip arthroscopy for femoroacetabular impingement between October 2014 and October 2019. Inclusion criteria consisted of complete Press-Ganey survey information, no history of trauma, fracture, connective tissue disease, developmental hip dysplasia, autoimmune disease, or previous hip arthroscopy. Groups were separated based on date of surgery relative to implementation of an institutional opioid reduction policy that occurred in October 2018. Prescriptions were converted to milligram morphine equivalents (MME) for direct comparison between different opioids. Results/UNASSIGNED:> .05). Conclusions/UNASSIGNED:A reduction in opioids prescribed after a hip arthroscopy is not associated with any statistically significant difference in patient satisfaction with pain management, as measured by the Press-Ganey survey. Level of Evidence/UNASSIGNED:Level III, retrospective comparative study.

Lower extremity injuries U.S national fencing team members and U.S fencing Olympians
Thompson, Kamali; Chang, Gregory; Alaia, Michael; Jazrawi, Laith; Gonzalez-Lomas, Guillem
Introduction: Fencing is growing rapidly in popularity and competitiveness with fencers beginning at a younger age and competing in more tournaments. Even though fencing has a low risk of time-loss injury, fencers are inevitably going to experience injuries if proper athletic training and prevention does not occur. We aim to describe and compare the lower extremity injuries experienced by fencers that have trained at the highest level in the sport. We hypothesized that athletes who fenced longer would suffer more knee and hip injuries and report lower IKDC and HOS scores.Methods: This is an epidemiology study distributed to members of the U.S national team and Olympic team from 1980 to 2018. The electronic survey included questions regarding age, weapon, number of years fencing, number of national and Olympic teams, injuries on the dominant and nondominant hip and knee, time missed due to injury, and methods for treatment. The survey also included the International Knee Demographic Committee (IKDC) and Hip Outcome Score (HOS).Results: There were 153 national team members between July 1980 and July 2018, 110 with contact information. A total of 77 athletes submitted the survey, consisting of 30 females and 47 males. Female fencers had more hip injuries and lower IKDC and HOS scores than their male counterparts. In total, there were 71 injuries to the dominant (front) knee and 28 injuries to the nondominant (back) knee. There were 32 dominant hip injuries and 5 nondominant hip injuries. Saber fencers reported the most dominant and nondominant hip and knee injuries.Conclusion: The intense, repetitive and asymmetrical movements involved in fencing affect the weight bearing leg and the nondominant leg in all weapons. Special attention should be paid to female fencers as they experience more hip and knee injuries resulting in impaired joint function.

Day-of-Surgery Video Calls and Phone Calls Increase Patient Satisfaction with Outpatient Surgery Experience: A Randomized Controlled Trial of Postoperative Communication Modalities
Kingery, Matthew T; Hoberman, Alexander; Baron, Samuel L; Gonzalez-Lomas, Guillem; Jazrawi, Laith M; Alaia, Michael J; Strauss, Eric J
BACKGROUND:With the increasing utilization of patient satisfaction as a metric for clinical care, there is growing interest in techniques that can be used to improve satisfaction in patients undergoing surgery. The purpose of this trial was to assess the impact of day-of-surgery video and phone calls on patient satisfaction. METHODS:We enrolled 251 patients undergoing outpatient orthopaedic surgery with 3 participating surgeons. Surgeons were randomized to 1 of 3 patient communication modalities: no contact (standard of care), phone call, or video call. Several hours following discharge on the day of surgery, the surgeons contacted patients according to their assigned treatment group. At the initial postoperative office visit, satisfaction outcomes were assessed using the Consumer Assessment of Healthcare Providers and Systems Surgical Care (S-CAHPS) survey and an additional satisfaction questionnaire. RESULTS:Fifty-nine (97%) of 61 patients in the no-contact group, 118 (99%) of 119 patients in the phone group, and 71 (100%) of 71 patients in the video group completed follow-up assessment. The S-CAHPS top-box response rate in both the video group (0.86 ± 0.14, p < 0.001) and the phone group (0.84 ± 0.17, p < 0.001) was greater than in the no-contact group (0.68 ± 0.26). When asked to rate satisfaction with overall care, a greater proportion of patients in the video group (85.9%) gave the top-box response compared with both the phone group (71.8%, p = 0.040) and the no-contact group (60.7%, p = 0.002). Among the patients in the video group, 62.0% indicated that they would prefer a video call in future encounters with their surgeon compared with 1.8% of patients in the no-contact group (p < 0.001) and 1.7% of patients in the phone group (p < 0.001). CONCLUSIONS:Phone and video calls following discharge are an effective way of enhancing patient satisfaction with the clinical care experience as measured by the S-CAHPS survey. In terms of satisfaction with overall care, video calls may be superior to phone calls. LEVEL OF EVIDENCE/METHODS:Therapeutic Level I.

Return to Play After Arthroscopic Stabilization for Posterior Shoulder Instability-A Systematic Review
Fried, Jordan W; Hurley, Eoghan T; Duenes, Matthew L; Manjunath, Amit K; Virk, Mandeep; Gonzalez-Lomas, Guillem; Campbell, Kirk A
Purpose/UNASSIGNED:To ascertain the rate and timing of return to play (RTP) and the availability of specific criteria for safe RTP after arthroscopic posterior shoulder stabilization. Methods/UNASSIGNED:Medline, EMBASE, and the Cochrane Library were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to find studies on arthroscopic posterior shoulder stabilization. Studies were included if they reported RTP data or rehabilitation protocols and excluded if concomitant procedures influenced the rehabilitation protocol. Rate and timing of RTP, along with rehabilitation protocols, were assessed. Results/UNASSIGNED:This review found 25 studies, including 895 cases, meeting the study's inclusion criteria. The majority of patients were male (82.7%), with an age range of 14 to 66 years and a follow-up range of 4 to 148.8 months. The overall RTP rate ranged from 62.7% to 100.0%, and 50.0% to 100.0% returned to the same level of play. Among collision athletes, the overall rate of RTP was 80.0% to 100.0%, with 69.2%-100.0% returning to the same level of play. In overhead athletes, the overall rate of RTP was 85.2% to 100.0%, with 55.6% to 100.0% returning to the same level of play. Four studies (128 patients) specifically addressed the timing of RTP, and the range to RTP was 4.3 to 8.6 months. Specific RTP criteria were reported in a majority of studies (60%), with the most reported item being restoration of strength (44%). Conclusion/UNASSIGNED:There is a high rate of return to sport after arthroscopic posterior shoulder stabilization, ranging from 4.3 to 8.6 months after surgery. Return to preinjury level is higher for collision athletes compared with overhead athletes. However, there is inadequate reporting of RTP criteria in the current literature, with no clear timeline for when it is safe to return to sport. Level of Evidence/UNASSIGNED:IV, systematic review of level II to IV studies.
