Abstract Acromioclavicular (AC) joint injuries are common and often require operative intervention. Although there are many described surgical techniques, there remains a lack of consensus on the optimal technique. The purpose of this Technical Note is to provide our preferred method of AC reconstruction with a recessed clavicular implant and semitendinosus allograft, which mitigates hardware pain associated with arthroscopic techniques.

Purpose To determine whether elbow torque was associated with anatomic adaptations of the medial elbow following a season of competitive pitching. Methods Pitchers from 3 collegiate baseball teams were recruited during the preseason for participation. Before the season, pitchers were recorded throwing 5 “game‐speed” fastball pitches from a standard distance off a mound while wearing a wearable sensor baseball compression sleeve that calculates elbow torque, arm speed, arm slot, and arm rotation. Participants subsequently underwent dynamic ultrasound imaging of the medial elbow, including measurements of the ulnar collateral ligament (UCL) and ulnohumeral joint space to assess elbow laxity. Following a full season of competitive pitching, all testing was repeated, and statistical analysis comparing preseason to postseason sonographic findings was performed. Results Twenty‐eight collegiate pitchers underwent preseason sonographic and kinematic testing. Nineteen pitchers were available for postseason testing. The average age (standard deviation) and playing experience was 19.9 (1.2) and 14.7 (1.5) years. Compared with preseason, there were significant increases in postseason UCL thickness (1.92 ± 0.09 vs 1.56 ± 0.09 mm, P < .01) and elbow laxity (1.77 ± 0.23 vs 1.15 ± 0.22 mm, P = .028) after a season of pitching. No significant changes in pitching kinematic measurements were observed between preseason and postseason testing. Preseason pitching kinematic measurements were significantly associated with increased UCL thickness (arm slot: beta estimate –0.03 ± 0.01, P = .011) and reduction in elbow laxity (elbow torque: beta estimate –0.03 ± 0.01, P = .04) after a season of pitching. Pitchers with increased body weight and arm length demonstrated reduced medial elbow torque during pitching ( P < .05). Conclusions After a season of competitive pitching, adaptive changes of the medial elbow were demonstrated on dynamic ultrasound. However, the influence of pitching kinematic measurements on these adaptations are of small magnitude and unknown clinical significance. Although wearable sensor technology may have value in trending individual pitcher kinematics, no discrete threshold appears to predict the development of adaptive changes at the elbow.

Purpose To evaluate the social media usage of orthopaedic residency programs, program directors (PDs), and department chairs across Instagram, Facebook, and Twitter and to determine which types of social media posts are indicative of increased user following. Methods A systematic online search strategy was performed in October 2020 to identify all allopathic orthopaedic surgery residency program accounts on Instagram, Facebook, and Twitter. Instagram posts were further analyzed to evaluate the type of post that significantly correlated with increased follower counts. Results Of 158 orthopaedic surgery programs, 69 (43.7%) had Instagram accounts, 52 (32.9%) had Facebook accounts, and 54 (34.2%) had Twitter accounts. Program presence on Instagram and Twitter continued to grow exponentially ( R 2 = 0.99 and R 2 = 0.95, respectively). Regarding program leadership, a total of 151 PDs and 156 chairs were identified. Of these, 21 PDs (14%) and 8 chairs (5.1%) had Instagram accounts. The number of posts and the numbers of educational, social, program information, and operative posts ( P < .01) significantly correlated with increased followers on Instagram. Conclusions Fewer than one‐half of orthopaedic surgery residency programs and fewer than one‐quarter of PDs and department chairs have a social media presence. However, the number of residency programs on social media continues to rise year‐over‐year. The total number of posts; the amount of educational, social, and program information; and the number of operative posts significantly correlated with increased followers on Instagram. Clinical Relevance With the growing prevalence of social media, orthopaedic surgery residency programs have the opportunity to connect with future applicants and disseminate informational content regarding their programs.

Purpose To quantify the financial impact of an anterior cruciate ligament (ACL) injury on the remaining career earnings of National Basketball Association (NBA) players. Methods We performed a retrospective review of all NBA players who had an ACL rupture between 2000 and 2019. Players were matched to healthy controls by age, position, body mass index, and player efficiency rating at the time of injury (index year). Player information collected included demographic information, position, team role, draft pick, date of injury, contract length, and earnings during the 3 years before and 7 years after the index year, as well as new contract length and earnings after injury. Results A total of 12 players (22%) did not return to play (RTP). No statistically significant difference in annual earnings was present at any time point between cohorts. When we examined the mean difference in earnings between the first 3 post‐index seasons and the 3 pre‐index seasons, both the ACL and control cohorts showed increased salaries as players’ careers progressed, without a significant difference in earnings. When comparing cohorts, we found no significant difference in the length and earnings of contracts during the index year. Furthermore, there was no significant difference in the length or earnings of the first new contract signed after the index year between cohorts. Additionally, NBA players who were able to RTP after ACL reconstruction were more likely to experience increased earnings if they had greater experience and performance prior to their injury ( P < .01). Conclusions Our study found that NBA players did not experience diminished earnings after RTP from an ACL reconstruction when compared with matched controls. Furthermore, no differences were seen in lengths of new contracts or in contract earnings between cohorts. Players with greater experience and performance prior to injury were more likely to have increased earnings after ACL reconstruction. Level of Evidence Level III, retrospective case‐control study.

Purpose To assess the effects of surgical treatment of athletic pubalgia (AP) on game use and performance metrics in National Basketball Association (NBA) players. Methods A retrospective review of all NBA players who underwent surgical management for AP from 1996 to 2018 was performed. A matched control group was created for comparison. The index period was defined as the entire NBA season in which surgery occurred, including the corresponding offseason. Player demographics, use (games played, games started, and minutes per game) and performance (player efficiency rating) metrics were collected for all players. Statistical analysis was performed to compare data before and after return to play. Results Thirty players with a history of surgical management for AP were included in the final analysis. Following surgery for AP, NBA players were found to have a return to play (RTP) rate of 90.91% (30/33). The average RTP following surgery was 4.73 ± 2.62 months. Compared with control athletes, athletes in the AP group played significantly fewer seasons postinjury (4.17 ± 2.70 vs 5.49 ± 3.04 seasons, respectively; P = .02). During the first year following RTP, NBA players experienced significant reductions in game use and performance, both when compared with the year prior and matched control athletes ( P < .05). At 3‐year follow‐up, players continued to demonstrate significant reductions in game use (minutes per game, P < .05) but not performance. Conclusions Following surgical treatment of AP, NBA players demonstrated a high RTP rate, but shortened career. A short‐term reduction in game use and performance metrics was found the year of return following surgery. However, 3‐year follow‐up performance metrics normalized when compared with healthy controls. Study Design Level III; retrospective case‐control study.

Purpose To investigate the demographic factors that influence time to respond (TTR), time to completion (TTC), and response rate when using a text messaging‐based system and to determine the feasibility and applicability of mobile messaging‐based services for collection of patient‐reported outcomes among orthopaedic sports medicine patients. Methods On the day of surgery, patient mobile phone number was collected and the automated mobile messaging service (MOSIO, Seattle, WA) messaged patients for 10 ``days postoperatively. Patient visual analog scale (VAS) scores were collected 3 times daily, side effects were asked each evening, and Patient‐Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI) Short Form was collected on postoperative day 3 and 7. Results A total of 177 patients were enrolled in the study. The overall response rate to the survey questions was 75.0%. For all patients, the average TTR of questions was 35.09 ± 12.57 minutes. The TTC was 2.75 ± 3.56 minutes for PROMIS‐PI, 3.51 ± 1.26 minutes for VAS, and 3.80 ± 6.87 for side‐effect questions. When patients were stratified into age groups, the youngest group, 16 to 32 years, had the greatest response rate of 85.2% and patients in the 49 to 59 years group had the lowest response rate of 68.4% and 69.1%, respectively ( P < .001). There was no significant difference in the TTR or TTC for VAS, PROMIS‐PI, or side‐effect questions when patients were stratified by age or sex groups ( P > .05). Conclusions Collectively, all age groups successfully achieved a mean response rate of 75%; however, significantly lower response rates were observed for patients >49 years old. Differences in age and sex did not impact the overall TTR or TTC for VAS, PROMIS‐PI, or side‐effect questions. Mobile‐based applications present as an emerging opportunity to track postoperative outcome scores and reduce clinic survey load. Level of Evidence Case series, level of evidence IV.

Purpose The purpose of this study is to evaluate differences in game utilization or performance following primary anterior cruciate ligament (ACL) reconstruction between National Football League (NFL) players with and without a second ACL injury. Methods NFL players who underwent ACL reconstruction between 2013 and 2017 were identified. Players were classified as having one injury (“tear”) or having later sustained a subsequent second (reinjury or contralateral) ACL injury (“retear”). Players were excluded if they tore their ACL prior to the NFL, did not return to play (RTP), did not play the season before injury, or had concomitant injuries. Demographic characteristics, game utilization statistics, and season approximate value (SAV) performance metrics were recorded. Statistical analysis compared data after RTP from primary ACL reconstruction (seasons +1, +2, and +3) relative to the season before injury (season −1) between cohorts using mean differences and relative percentages. Results Analysis included a total of 45 players, 32 in the “tear” group and 13 in the “retear” group. Demographics, level of play, and time to RTP after primary ACL reconstruction did not differ between the groups ( P > .05). Tear and retear groups demonstrated similar utilization and performance metrics the season prior to injury (−1) and the 3 seasons following RTP (season of injury is “0”). Both groups had a similar decrease (relative percentage) in games played and started, snap counts, and SAV during the 3 seasons following RTP compared to baseline ( P > .05). The draft pick position was correlated with the relative percentage of games started the first season after RTP ( r = .6, P = .02). Conclusions Game utilization and performance metrics following ACL reconstruction were not associated with a subsequent second ACL injury. Players with a higher draft pick position were more likely to return to the starting lineup following primary ACL reconstruction. Ultimately, player game utilization and performance following primary ACL reconstruction is not predictive of a subsequent second ACL injury.

Purpose The purpose of this study is to analyze the Instagram practices of current orthopaedic surgeons and the components associated with highest reach and interactions. Methods The top 25 orthopaedic surgeon Instagram profiles using the hashtag #ortho were ranked by the number of followers. Account information regarding followers, posts, engagement percentage, average likes, average comments, average video view, average video likes, average video comments, and estimated cost per post was recorded using social media marketing tools. An analysis of each Instagram profiles’ top 10 posts, based on number of likes, was conducted. A coding framework was developed to categorized posting strategies utilized. Results Twenty‐five Instagram accounts and 250 Instagram posts were included in the analysis. Accounts with increased engagement rating had a significantly greater number of likes and video views. When examining post characteristics that influenced the number of likes a post generated, posts that elicited negative emotions received 52.6% and 70.7% more likes than positive emotions ( P = .04) and neutral emotions ( P < .01), respectively. Upon assessment of posting characteristics that influenced the number of comments a post generated, promotional posts were shown to have 43.7% fewer comments than nonpromotional posts ( P = .02). When evaluating factors that influenced total number of interactions a post generated, it was found that posts that asked questions generated 26.4% more interactions ( P < .01) than those that do not. Conclusions The present investigation found that the most effective strategies to generate more interactions on Instagram are those that elicit emotional responses and provoke viewer engagement by asking questions and directing actions. Additionally, it was found that promotional content was not well received by viewers. Clinical Relevance Orthopaedic surgeons have an opportunity to connect with colleagues, patients, and interested viewers through social media platforms in order to enhance their practice, disseminate educational content, and contribute to the social media presence of orthopaedic surgery.

» In the United States, orthopaedic surgeons have a legal obligation to obtain informed consent from patients before performing surgery; it is a process that includes a signed written document. » There are specific legal requirements that vary somewhat by state but generally include disclosure and documentation of the diagnosis, an explanation of the recommended procedure, a conversation about the risks and benefits of the procedure, and a discussion about alternative treatments. » Inadequate disclosure of risks and alternatives is associated with increased indemnity risk. » Studies have shown that many consent processes and forms are suboptimal.

Abstract Posterolateral corner (PLC) reconstruction has been shown to be an effective treatment for PLC injuries. Acute anatomical repair of the PLC has the same potential to stabilize the knee; however, outcomes are less defined. Surgical repair minimizes graft harvest morbidity and allows for the maintenance of native tissue proprioception. Furthermore, augmentation with a flat‐braided suture (SutureTape; Arthrex) portends additional repair strength and protection. The purpose of this Technical Note and video is to provide our preferred method of PLC repair in a patient with an acute knee dislocation and injury to the biceps femoris, lateral collateral ligament, iliotibial band, popliteofibular ligament, and the meniscocapsular attachment of the lateral meniscus.
