Editorial Commentary: Load Management Is Essential to Prevent Season-Ending Injuries in the National Basketball Association.

Each season, National Basketball Association (NBA) athletes subject themselves to a physical season including a minimum of 82 games, intense travel, participation during holidays, innumerable training sessions, and for some, playoffs continuing into June. Intensity and fatigue may contribute to a high rate of injuries, and recent literature has suggested that primary risk factors for season-ending injuries are minutes played per game and later season games. Scheduled periods of rest, or load management, reduce the physiological load a player endures during a grueling season. Disadvantages of load management may include decrements in individual skill, team competitiveness, and financial issues, including disappointed fans. Thus, in 2023, the NBA instituted the Player Participation Policy (PPP) placing stipulations on load management by asking teams to balance player rest between home and away games and to refrain from long-term shutdowns of player participation for nonmedical reasons. From a medical standpoint, safeguarding athlete health is of paramount importance. Managing the workload of NBA players may have numerous player benefits and must be achieved while mitigating the disadvantages.

Outcomes of total shoulder arthroplasty in patients with prior anterior shoulder instability: minimum 5-year follow-up.

BACKGROUND: Patients with a history of anterior shoulder instability (ASI) commonly progress to glenohumeral arthritis or even dislocation arthropathy and often require total shoulder arthroplasty (TSA). The purposes of this study were to (1) report patient-reported outcomes (PROs) after TSA in patients with a history of ASI, (2) compare TSA outcomes of patients whose ASI was managed operatively vs. nonoperatively, and (3) report PROs of TSA in patients who previously underwent arthroscopic vs. open ASI management. METHODS: Patients were included if they had a history of ASI and had undergone TSA ≥5 years earlier, performed by a single surgeon, between October 2005 and January 2017. The exclusion criteria included prior rotator cuff repair, hemiarthroplasty, or glenohumeral joint infection before the index TSA procedure. Patients were separated into 2 groups: those whose ASI was previously operatively managed and those whose ASI was treated nonoperatively. This was a retrospective review of prospective collected data. Data collected was demographic, surgical and subjective. The PROs used were the American Shoulder and Elbow Surgeons score, Single Assessment Numerical Evaluation score, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score, and 12-item Short Form physical component score. Failure was defined as revision TSA surgery, conversion to reverse TSA, or prosthetic joint infection. Kaplan-Meier survivorship analysis was performed. RESULTS: This study included 36 patients (27 men and 9 women) with a mean age of 56.4 years (range, 18.8-72.2 years). Patients in the operative ASI group were younger than those in the nonoperative ASI group (50.6 years vs. 64.0 years, P < .001). Operative ASI patients underwent 10 open and 11 arthroscopic anterior stabilization surgical procedures prior to TSA (mean, 2 procedures; range, 1-4 procedures). TSA failure occurred in 6 of 21 patients with operative ASI (28.6%), whereas no failures occurred in the nonoperative ASI group (P = .03). Follow-up was obtained in 28 of 30 eligible patients (93%) at an average of 7.45 years (range, 5.0-13.6 years). In the collective cohort, the American Shoulder and Elbow Surgeons score, Single Assessment Numerical Evaluation score, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score, and 12-item Short Form physical component score significantly improved, with no differences in the postoperative PROs between the 2 groups. We found no significant differences when comparing PROs between prior open and prior arthroscopic ASI procedures or when comparing the number of prior ASI procedures. Kaplan-Meier analysis demonstrated a 79% 5-year survivorship rate in patients with prior ASI surgery and a 100% survivorship rate in nonoperatively managed ASI patients (P = .030). CONCLUSION: At mid-term follow-up, patients with a history of ASI undergoing TSA can expect continued improvement in function compared with preoperative values. However, TSA survivorship is decreased in patients with a history of ASI surgery compared with those without prior surgery.

Blood Flow Restriction Therapy for 2 Weeks Prior to Anterior Cruciate Ligament Reconstruction Did Not Impact Quadriceps Strength Compared to Standard Therapy.

PURPOSE: To evaluate the efficacy of a 2-week home-based blood flow restriction (BFR) prehabiliation program on quadriceps strength and patient-reported outcomes prior to anterior cruciate ligament (ACL) reconstruction. METHODS: Patients presenting with an ACL tear were randomized into two groups, BFR and control, at their initial clinic visit. Quadriceps strength was measured using a handheld dynamometer in order to calculate peak force, average force, and time to peak force during seated leg extension at the initial clinic visit and repeated on the day of surgery. All patients were provided education on standardized exercises to be performed 5 days per week for 2 weeks between the initial clinic visit and date of surgery. The BFR group was instructed to perform these exercises with a pneumatic cuff set to 80% of limb occlusion pressure placed over the proximal thigh. Patient-Reported Outcome Measurement System Physical Function (PROMIS-PF), knee range of motion, and quadriceps circumference were gathered at the initial clinic visit and day of surgery, and patients were monitored for adverse effects. RESULTS: A total 45 patients met inclusion criteria and elected to participate. There were 23 patients randomized to the BFR group and 22 patients randomized into the control group. No significant differences were noted between the BFR and control groups in any demographic characteristics (48% vs 64% male [P = .271] and average age 26.5 ± 12.0 vs 27.0 ± 11.0 [P = .879] in BFR and control, respectively). During the initial clinic visit, there were no significant differences in quadriceps circumference, peak quadriceps force generation, time to peak force, average force, pain, and PROMIS scales (P > .05 for all). Following completion of a 2-week home prehabilitation protocol, all patients indeterminant of cohort demonstrated decreased strength loss in the operative leg compared to the nonoperative leg (P < .05 for both) However, there were no significant differences in any strength or outcome measures between the BFR and control groups (P > .05 for all). There were no complications experienced in either group, and both were compliant with the home-based prehabilitation program. CONCLUSIONS: A 2-week standardized prehabilitation protocol preceding ACL reconstruction resulted in a significant improvement in personal quadriceps peak force measurements, both with and without the use of BFR. No difference in quadriceps circumference, strength, or patient reported outcomes were found between the BFR and the control group. The home-based BFR prehabiliation protocol was found to be feasible, accessible, and well tolerated by patients. LEVEL OF EVIDENCE: Level II, randomized controlled trial with small effect size.

Machine Learning Model Identifies Preoperative Opioid Use, Male Sex, and Elevated Body Mass Index as Predictive Factors for Prolonged Opioid Consumption Following Arthroscopic Meniscal Surgery.

PURPOSE: To develop a predictive machine learning model to identify prognostic factors for continued opioid prescriptions after arthroscopic meniscus surgery. METHODS: Patients undergoing arthroscopic meniscal surgery, such as meniscus debridement, repair, or revision at a single institution from 2013 to 2017 were retrospectively followed up to 1 year postoperatively. Procedural details were recorded, including concomitant procedures, primary versus revision, and whether a partial debridement or a repair was performed. Intraoperative arthritis severity was measured using the Outerbridge Classification. The number of opioid prescriptions in each month was recorded. Primary analysis used was the multivariate Cox-Regression model. We then created a naïve Bayesian model, a machine learning classifier that uses Bayes' theorem with an assumption of independence between variables. RESULTS: A total of 581 patients were reviewed. Postoperative opioid refills occurred in 98 patients (16.9%). Multivariate logistic modeling was used; independent risk factors for opioid refills included male sex, larger body mass index, and chronic preoperative opioid use, while meniscus resection demonstrated decreased likelihood of refills. Concomitant procedures, revision procedures, and presence of arthritis graded by the Outerbridge classification were not significant predictors of postoperative opioid refills. The naïve Bayesian model for extended postoperative opioid use demonstrated good fit with our cohort with an area under the curve of 0.79, sensitivity of 94.5%, positive predictive value (PPV) of 83%, and a detection rate of 78.2%. The two most important features in the model were preoperative opioid use and male sex. CONCLUSION: After arthroscopic meniscus surgery, preoperative opioid consumption and male sex were the most significant predictors for sustained opioid use beyond 1 month postoperatively. Intraoperative arthritis was not an independent risk factor for continued refills. A machine learning algorithm performed with high accuracy, although with a high false positive rate, to function as a screening tool to identify patients filling additional narcotic prescriptions after surgery. LEVEL OF EVIDENCE: III, retrospective comparative study.

Availability of Consumer Prices for Arthroscopic Meniscus Surgery.

The purpose is to examine the availability of consumer pricing information for arthroscopic meniscal surgery in the United States. Secondary objectives were comparing the price of meniscal repair to meniscectomy and regional pricing differences. Orthopaedic sports medicine clinics were sorted by state and randomly selected from American Orthopaedic Society for Sports Medicine's online directory. Following standardized script, each clinic was called a maximum of three times to obtain pricing information for meniscal surgery. A total of 1,008 distinct orthopaedic sport medicine practices were contacted. Six (6%) clinics were able to provide complete bundle pricing, and 183 (18.2%) clinics were able to provide physician-only fees for either meniscectomy or meniscal repair. Physician-only fees and bundle pricing were significantly less for meniscal repairs as compared to meniscectomies. There were no geographic regional differences in pricing for physician-only fees. There is a paucity of information regarding price transparency for arthroscopic meniscal surgery. (Journal of Surgical Orthopaedic Advances 32(2):083-087, 2023).

Editorial Commentary: Postoperative Alpha Angle and Return to Sport: One Piece of the Puzzle.

Return-to-sport rates following arthroscopic treatment of femoroacetabular impingement are high; however, the predictors of failure to return to sport must be elucidated. Recent data suggest that the postoperative alpha angle may be a significant predictor of return to sport in athletes, despite the fact that the role of radiographic measurements on postoperative outcomes is debated in the literature. Nonetheless, it is incumbent on surgeons to fully understand the unique biomechanics of the hip in each sport and consider each patient's unique anatomy when undertaking cam resection. Recreation of the motion at-risk during a careful intraoperative dynamic examination is imperative to ensure that all areas of impingement have been eradicated while attentively avoiding over-resection. While the postoperative alpha angle is an important metric for surgeons to keep in mind, it may only represent one piece of the puzzle.

Multimodal Nonopioid Pain Protocol Provides Better or Equivalent Pain Control Compared to Opioid Analgesia Following Arthroscopic Rotator Cuff Surgery: A Prospective Randomized Controlled Trial.

PURPOSE: To evaluate the efficacy of a multimodal nonopioid analgesic protocol in controlling postoperative pain compared to opioids following a primary arthroscopic rotator cuff repair. METHODS: Seventy consecutive patients undergoing a primary rotator cuff repair were assessed for eligibility. An observer-blinded prospective randomized controlled trial was designed in accordance with the Consolidated Standards of Reporting Trials 2010 (CONSORT) statement. The two arms of the study included a multimodal nonopioid pain regimen for the experimental group, and a standard of care narcotics for the control group. The primary outcome was visual analog scale (VAS) pain scores for the first 10 postoperative days. Secondary outcomes included PROMIS-PI (Patient-Reported Outcomes Measurement Information System-Pain Interference) scale, patient satisfaction, and adverse drug events. RESULTS: Thirty patients declined to participate or were excluded, and 40 patients were included in the final analysis. A total of 23 patients were in the traditional group, and 17 patients were in the nonopioid group. Control patients on opioid pain management reported a significantly higher VAS pain score on postoperative day 1 (opioid: 5.7 ± 2, nonopioid: 3.7 ± 2.2; P = .011) and postoperative day 4 (opioid: 4.4 ± 2.7, nonopioid: 2.4 ± 2.2; P = .023). No significant difference was seen on any other postoperative day. When mixed measured models were used to control for confounding factors, the nonopioid group demonstrated significantly lower VAS and PROMIS-PI scores (P < .01) at every time point. Patients in the traditional analgesia group reported significantly more days with constipation (P = .003) and days with upset stomach (P = .020) than those in the nonopioid group. CONCUSSION: The present study found that a multimodal nonopioid pain protocol provided equivalent or better pain control compared to traditional opioid analgesics in patients undergoing primary arthroscopic rotator cuff repair. Minimal side effects were noted with some improvement in the multimodal nonopioid pain cohort. All patients reported satisfaction with their pain management. LEVEL OF EVIDENCE: Level I, prospective randomized controlled trial.

The impact of external beam radiation therapy on shoulder surgical outcomes: a case series study.

HYPOTHESIS: External beam radiation therapy (XRT) is a commonly used treatment adjunct in patients with breast cancer and is known to cause soft tissue dysfunction. However, data on XRT as a preoperative risk factor for shoulder surgery is limited. The purpose of this study was to assess whether prior history of breast cancer treated with XRT has an impact on surgical complications or outcomes. We hypothesize that patients treated with XRT will have a higher rate of surgical complications and lower outcomes. METHODS: A 20-year retrospective chart review across a large, academic health care system was performed. Inclusion criterion comprised any patient with history of breast cancer of the upper-outer or axillary region treated with XRT. Patients also must have undergone a surgical procedure to the ipsilateral shoulder with at least 1-year postoperative follow-up. Patients were stratified by demographics, hand dominance, and surgery type. Postoperative outcomes including range of motion (ROM) and visual analog scale (VAS) scores for pain were also collected. RESULTS: Eighteen patients were identified (100% female) with an average age of 66.3 years (standard deviation 10.5 years). Ten shoulders underwent rotator cuff repair (RCR), 4 total shoulder arthroplasty (TSA), 3 reverse shoulder arthroplasty (RSA), and 1 arthroscopic superior labrum anterior to posterior (SLAP) repair. Four patients treated with RCR (40%) experienced postoperative complications related to their procedure. These included scapular winging, adhesive capsulitis, stiffness, and one retear. Two patients treated with shoulder arthroplasty (28.6%) experienced postoperative complications that included lymphedema and periprosthetic fracture following a mechanical fall in one RSA patient and periprosthetic infection in a TSA patient. ROM across all groups improved, most significantly in forward flexion and internal rotation among RCR patients (P < .001). Furthermore, a statistically significant improvement in VAS scores was achieved in each group (6.2 ± 2.14 preoperation, 1.06 ± 1.75 postoperation; P < .001). CONCLUSION: When compared to national averages, complication rates in our cohort were higher (40% vs. 10%-17% in RCR patients and 28.6% vs. 4%-14% in arthroplasty patients). On further scrutiny, many of these complications were independent of a history of XRT and many resolved with appropriate therapy. Most importantly, functional outcomes as measured by ROM and pain scores showed appropriate improvement consistent with normal populations without history of XRT. Thus, our results suggest that performing shoulder surgery after ipsilateral XRT for breast cancer is likely safe and may offer improved pain and ROM compared to forgoing surgery without necessarily increasing the risk for postoperative complication.

Multimodal Nonopioid Pain Protocol Provides Equivalent Pain Versus Opioid Control Following Meniscus Surgery: A Prospective Randomized Controlled Trial.

PURPOSE: To assess the effectiveness of a nonopioid pain regimen in controlling postoperative pain as compared with a traditional opioid pain control following primary meniscectomy or meniscal repair. METHODS: Ninety-nine patients undergoing primary meniscectomy or meniscal repair were assessed for participation. A prospective randomized control trial was performed in accordance with the Consolidated Standards of Reporting Trials 2010 statement. The 2 arms of the study included a multimodal nonopioid analgesic protocol and a standard opioid regimen with a primary outcome of postoperative pain level (visual analog scale) for the first 10 days postoperatively. Secondary outcomes included patient-reported outcomes, complications, and patient satisfaction. Randomization was achieved using a random-number generator. Patients were not blinded. Data collection was done by a blinded observer. RESULTS: Eleven patients did not meet the inclusion criteria, and 27 declined participation. A total of 61 patients were analyzed with 30 randomized to the opioid regimen and 31 randomized to the nonopioid regimen. Patients receiving the nonopioid regimen demonstrated noninferior visual analog scale scores compared with patients who received opioid pain medication (P > .05). No significant differences were found in preoperative (opioid: 58.9 ± 7.0; nonopioid: 58.2 ± 5.5, P = .724) or postoperative (opioid: 59.8 ± 6.5; nonopioid: 54.9 ± 7.1, P = .064) Patient-Reported Outcomes Measurement and Information System Pain Interference Short Form scores. No difference was found in recorded side effects between both groups at any given time point: constipation, nausea, diarrhea, upset stomach, and drowsiness (P > .05). CONCLUSIONS: This study found that a multimodal nonopioid pain protocol provided equivalent pain control and patient outcomes following primary meniscus surgery while having an equivalent side effect profile. All patients reported satisfaction with their pain management without requiring emergency opioid analgesia. LEVEL OF EVIDENCE: Level I, prospective randomized controlled trial.

Career Longevity and Performance After Shoulder Instability in National Football League Athletes.

PURPOSE: To investigate the career longevity, game utilization, and performance of National Football League (NFL) athletes after glenohumeral instability events treated operatively versus nonoperatively. METHODS: Using public resources, we identified NFL players who sustained a shoulder instability event from September 2000 to February 2019. Players with prior shoulder instability, without NFL experience before injury, or who did not return to play (RTP) after injury were excluded. Demographic information, utilization (games and seasons), and season approximate value (SAV) statistics were recorded 1 year prior to injury and 3 years after RTP. Statistical analysis compared utilization and the SAV after RTP for athletes managed operatively versus nonoperatively. RESULTS: We identified 97 NFL players who sustained their first instability event while playing in the NFL, 91 of whom returned to play (93.8%). Quarterbacks were significantly more likely to undergo immediate surgical management compared with players in other positions (P = .023). The final analysis included 58 players managed operatively and 33 managed nonoperatively by the end of the index season. Players treated operatively played in significantly more seasons after RTP during their remaining careers (4.1 ± 2.7 seasons vs 2.8 ± 2.5 seasons, P = .015). There were no differences in games played or started, offensive or defensive snap count percentage, or performance (SAV) before and after injury when compared between cohorts (P > .05). After surgical stabilization, time to RTP (36.62 ± 10.32 weeks vs 5.43 ± 12.33 weeks, P < .05) and time interval before recurrent instability (105.7 ± 100.1 weeks vs 24.7 ± 40.6 weeks, P < .001) were significantly longer than with nonoperative treatment. Additionally, the operative cohort experienced less recurrent instability (27% vs 50%, P = .035). CONCLUSIONS: Athletes who RTP in the NFL after a shoulder instability injury do so with a similar workload and performance irrespective of surgical or nonsurgical management. Whereas nonoperative treatment is associated with faster RTP, operative management is associated with fewer recurrent instability events, greater time between recurrent instability events, and greater career longevity. LEVEL OF EVIDENCE: Level III, retrospective case-control study.

Multimodal nonopioid pain protocol provides equivalent pain control versus opioids following arthroscopic shoulder labral surgery: a prospective randomized controlled trial.

BACKGROUND: This study aimed to compare postoperative pain and patient satisfaction in patients undergoing primary arthroscopic labral surgery managed with either a nonopioid alternative pain regimen or a traditional opioid pain regimen. METHODS: Sixty consecutive patients undergoing primary arthroscopic shoulder labral surgery were assessed for participation. In accordance with the Consolidated Standards of Reporting Trials (CONSORT) 2010 statement, a prospective randomized controlled trial was performed. The 2 arms of the study were a multimodal nonopioid analgesic protocol as the experimental group and a standard opioid regimen as the control group. The primary outcome was postoperative pain scores (on a visual analog scale [VAS]) for the first 10 days postoperatively. Secondary outcomes included patient satisfaction, patient-reported outcomes, and complications. Randomization was performed with a random number generator, and all data were collected by blinded observers. Patients were not blinded. RESULTS: Twelve patients did not meet the inclusion criteria or declined to participate. Thus, 48 patients were included in the final analysis: 24 in the nonopioid group and 24 in the opioid group. There was no significant difference in VAS or PROMIS (Patient-Reported Outcomes Measurement Information System) scores between patients in the 2 cohorts on any postoperative day (P > .05). When we controlled for confounding factors with repeated-measures mixed models, the nonopioid cohort reported significantly lower VAS and PROMIS (Patient-Reported Outcomes Measurement Information System) Pain Interference scores (P < .01) at all time points. No difference was found in reported adverse events (constipation, diarrhea, drowsiness, nausea, and upset stomach) between cohorts at any time point (P > .05). CONCLUSION: This study found that a multimodal nonopioid pain regimen provided, at the minimum, equivalent pain control, an equivalent adverse reaction profile, and equivalent patient satisfaction when compared with a standard opioid-based regimen following arthroscopic shoulder labral surgery.

The relationship between shoulder range of motion and elbow stress in college pitchers.

HYPOTHESIS: College pitchers with increased external rotation gain (ERG) produce increased medial elbow torque (elbow stress) whereas those with reduced total rotational range of motion (ROM) have reduced medial elbow torque during pitching. METHODS: Pitchers were recruited from 3 college baseball teams. Players with prior injury or on pitching restrictions because of pain were excluded. Players were evaluated within 2 weeks before their first game of the season. Pitchers completed an intake survey, and shoulder and arm measurements were taken. Pitchers were fitted with a baseball sleeve that included a sensor at the medial elbow. The sensor calculated elbow torque, arm speed, arm slot, and shoulder rotation for each pitch, while a radar gun measured peak ball velocity. After adequate warm-up, pitchers threw 5 fastballs in a standardized manner off the mound at game-speed effort. The primary outcome evaluated the relationship between shoulder ROM and medial elbow torque. Additional outcomes evaluated pitcher characteristics and demographic characteristics in the context of shoulder ROM. RESULTS: Twenty-eight pitchers were included in the preseason analysis. The average age and playing experience were 20.1 years (standard deviation [SD], 1.3 years) and 15.3 years (SD, 1.8 years), respectively, with 2.5 years (SD, 1.2 years) playing at collegiate level. The dominant shoulder showed decreased internal rotation and increased external rotation (ER) relative to the nondominant side (P < .001). The average glenohumeral internal rotation deficit and ERG were 11.3° (SD, 9.87°) and 5.71° (SD, 8.8°), respectively. ERG ≥ 5° was a significant predictor of elbow stress during pitching (47.4 Nm [SD, 0.7 Nm] vs. 45.1 Nm [SD, 0.6 Nm], P = .014). Univariate associations showed that each additional degree of ER resulted in increased elbow torque (ß estimate, 0.35 ± 0.06 Nm; P = .003). Conversely, decreased medial elbow torque was found in pitchers with reduced shoulder ROM (glenohumeral internal rotation deficit ≥ 20°: 43.5 Nm [SD, 1.1 Nm] vs. 46.6 Nm [SD, 0.5 Nm], P = .011; loss of total rotational ROM ≥ 5°: 43.6 Nm [SD, 1.1 Nm] vs. 46.6 Nm [SD, 0.5 Nm], P = .013) and in those with greater arm length (P < .05). CONCLUSIONS: College pitchers with increased ER produce greater medial elbow torque during the pitching movement. Each degree of increased ER was found to correlate with increased elbow torque and ball velocity. On the contrary, arm length and reduced shoulder ROM were associated with reduced medial elbow torque. This study suggests that increased ER in pitchers is associated with greater elbow stress during pitching.

Editorial Commentary: Postoperative Analgesia After Arthroscopy: A Step Toward the Personalization of Pain Control.

Identification of risk factors for prolonged opioid use is imperative as opioid misuse continues to plague society. Recent data suggest that many modifiable and nonmodifiable patient factors may be associated with prolonged opioid use after arthroscopic meniscal surgery. Surgeons and patients share the burden of the opioid epidemic and must collaborate to decrease the overall opioid burden on society. As the number of tools to treat pain and the knowledge of at-risk patients grow, standardized postoperative narcotic regimens to treat a diverse population of patients are no longer acceptable; narcotic regimens must be customized to each patient. To limit opioid use and enhance patient outcomes, it is apparent that the next frontier of postoperative pain control is upon us: the personalization of pain control.

A Multimodal Protocol to Diminish Pain Following Common Orthopedic Sports Procedures: Can We Eliminate Postoperative Opioids?

PURPOSE: To determine whether postsurgical pain, measured by the visual analog scale (VAS), following common orthopaedic sports procedures could be managed effectively with a nonopioid multimodal analgesic protocol. METHODS: This prospective study evaluated a custom multimodal nonopioid pain protocol in patients undergoing common orthopaedic sports procedures by a single fellowship-trained orthopaedic sports surgeon from May 2018 to December 2018. Procedures included anterior cruciate ligament reconstruction, rotator cuff repair, arthroscopic partial meniscectomy, and labrum repair. The nonopioid pain protocol consisted of preoperative analgesics, intraoperative local infiltration analgesia, and a postoperative pain regimen. Patient pain was immediately reported after surgery and 1 week postoperatively using the VAS, whereas rescue opioids (oxycodone 5 mg) used were recorded using a prescription opioid journal. Statistical analysis of patient VAS scores, demographic correlations, and comparison between opioid rescue users versus nonusers was performed. RESULTS: A total of 141 patients were included. One week following surgery, patients reported a mean VAS level of 3.2 ± 2.3 and required on average 2.6 ± 3.6 breakthrough oxycodone pills (8.6 ± 12.0 morphine equivalents). Forty-five percent of patients did not require any breakthrough prescription opioids and reported satisfaction with pain management. Patients who required opioids were more likely to have a history of anxiety/depression (44.2% vs 23.8%, P = .012) and reported greater pain scores as compared with nonusers (3.94 ± 2.5 vs 2.41 ± 1.75, P = .016). The most common side effect of the pain protocol was feeling drowsy (23.5%). All patients were satisfied with their pain management postoperatively. CONCLUSIONS: A multimodal, nonopioid pain protocol was found to be effective in managing postoperative pain following common orthopedic sports procedures. Patients were found to have low levels of pain, require minimal rescue opioids, and had no severe side effects related to the protocol. These results suggest a nonopioid alternative to pain management following common orthopedic sports procedures. LEVEL OF EVIDENCE: Level IV, prospective case series.

Risk Factors for Postoperative Opioid Use in Arthroscopic Shoulder Labral Surgery.

PURPOSE: To determine the correlation between preoperative and postoperative opioid use in patients undergoing arthroscopic shoulder labral repair, as well as patient risk factors associated with increased postoperative opioid use after the procedure. METHODS: A retrospective review of all patients undergoing arthroscopic shoulder labral surgery at a single institution between August 2013 and November 2017 was performed. Patients were stratified as opioid nonusers, acute users, or chronic users based on preoperative consumption. Patient demographic characteristics, injury characteristics, surgical interventions, and postoperative opioid use for the first 12 months after surgery were then analyzed. RESULTS: A total of 340 patients were included in this study. The average age was 26.3 years (range, 13-68 years), and the average body mass index was 27.5 (range, 18.4-45.0). Preoperative opioid users (acute and chronic) were found to continue to receive opioid medications at extended time points beyond 2 months postoperatively compared with nonusers (P < .001). Patients with intraoperatively identified SLAP tears experienced more preoperative pain and required more postoperative opioid prescriptions (P = .018). On stratification for other common shoulder instability injury patterns, no differences were found between the number of postoperative opioid prescriptions filled and the presence of Bankart lesion, Hill-Sachs lesion, reverse Hill-Sachs lesion, anterior labroligamentous periosteal sleeve avulsion, glenolabral articular disruption, or humeral avulsion of the glenohumeral ligament (P > .05). CONCLUSIONS: In patients undergoing arthroscopic labral surgery, the chronicity of preoperative opioid use, number of concomitant procedures at the time of initial surgery, and presence of biceps tenodesis were found to significantly increase postoperative opioid demand. Orthopaedic surgeons should recognize risk factors for increased opioid use postoperatively and adapt treatment strategies and patient counseling accordingly. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Importance of radar gun inclusion during return-to-throwing rehabilitation following ulnar collateral ligament reconstruction in baseball pitchers: a simulation study.

BACKGROUND: Rehabilitation following elbow ulnar collateral ligament reconstruction in baseball pitchers relies on a progression of pitching activities to ensure protection and gradual strengthening of the reconstructed ligament. The purpose of this study was to determine the medial elbow torque associated with pitches at various effort levels and determine whether radar gun assistance improves players' abilities to accurately match partial-effort pitches with true references based on maximum pitch velocity. METHODS: Thirty-seven healthy high school and collegiate baseball pitchers were included in this study. Participants were excluded if they were injured, recovering from injury, or otherwise not currently pitching at full effort. Pitch parameters were collected using a validated wearable sensor. Participants threw 5 pitches at 50%, 75%, and 100% subjective effort. Pitchers then threw 5 pitches at 50% maximum velocity and 75% maximum velocity, as measured by a radar gun. RESULTS: Thirty-seven pitchers completed this study. Pitches thrown at 50% and 75% partial effort were significantly faster and generated higher elbow torque than did pitches thrown at 50% and 75% velocity, respectively (P < .001). A 10% decrease in percentage of maximum velocity was associated with a 13% decrease in percentage of maximum elbow torque (ß coefficient = 1.3, R2 = 0.81, P < .001). CONCLUSION: Pitchers generate higher-than-intended forces when throwing at 50% and 75% effort during a subjective partial-effort throwing protocol. Use of a radar gun to guide partial-effort throwing during throwing rehabilitation programs may protect the reconstructed elbow from excess medial torque.

Risk Factors for Postoperative Opioid Use in Arthroscopic Meniscal Surgery.

PURPOSE: (1) To evaluate the influence of preoperative opioid use on postoperative consumption after arthroscopic meniscal surgery and (2) to determine preoperative patient factors associated with increased opioid use after meniscal surgery. METHODS: We performed a retrospective review of all patients with a primary diagnosis of a meniscal tear at a single institution between August 2013 and February 2017. Patients were classified as opioid nonusers if they had not received any opioid medications in the 3 months before meniscal surgery, as acute users if they received at least 1 opioid prescription within 1 month preceding meniscal surgery, or as chronic users if they received at least 1 opioid prescription within 3 months preceding meniscal surgery. Clinical records were reviewed for postoperative opioid use within a year after surgery. We also recorded patient demographic characteristics and the degree of knee osteoarthritis at the time of surgery using the Outerbridge classification. RESULTS: A total of 735 patients were included. The average age was 46.7 years (range, 12-79 years), and the average body mass index was 30.2 ± 6.2 (range, 13.3-55.4). Patients who were acute or chronic opioid users preoperatively were more likely to continue to use opioids beyond 1 month postoperatively (P < .001). A higher percentage of patients with advanced osteoarthritis (Outerbridge grade 3 or 4) were found to continue to use opioids at all time points beyond the first postoperative month (P < .05). Pair-wise comparisons showed that the number of total opioid prescriptions filled was significantly higher in the group with Outerbridge grade 1 or 2 and the group with Outerbridge grade 3 or 4 than the group with Outerbridge grade 0 (P = .023 and P = .014, respectively). No significant difference in postoperative opioid use was noted when we compared meniscal repair versus resection, primary procedure versus revision, different tear types, or concomitant procedures. CONCLUSIONS: In patients undergoing arthroscopic meniscal surgery, the chronicity of preoperative opioid intake and degree of knee osteoarthritis were found to have a significant effect on postoperative opioid use. LEVEL OF STUDY: Level III, retrospective comparative study.

Abnormal tibial alignment is a risk factor for lateral meniscus posterior root tears in patients with anterior cruciate ligament ruptures.

PURPOSE: The purpose of this study was to identify if abnormal tibial alignment was a risk factor for lateral meniscus posterior root tears (LMPRT) in patients with acute anterior cruciate ligament (ACL) ruptures. METHODS: The medical charts of 200 patients treated for ACL ruptures between 2013 and 2016 were retrospectively reviewed and evaluated. MRI images and reports were assessed for concurrent meniscal tears. Radiographs were reviewed for tibia vara and tibial slope angles and MRI reports identifying lateral root tears were compared to intraoperative reports to determine accuracy. Multiple logistic regression models were constructed to identify potential risk factors for LMPRTs. RESULTS: Of the 200 patients reviewed, a total of 97 individuals with concurrent meniscal injuries were identified. In patients sustaining a concurrent meniscal injury, there was a 4% incidence of medial meniscus posterior root tears and a 10.3% incidence of LMPRTs. Patients sustaining an ACL injury with an LMPRT were found to have greater tibia vara angles (4.2 ± 1.0 vs. 2.9 ± 1.7; p = 0.024), increased tibial slopes (12.6 ± 1.5 vs. 10.7 ± 2.9; p = 0.034), and higher BMIs (27.3 ± 2.9 vs. 25.3 ± 5.9; p = 0.034) when compared to patients without meniscus tears. There was low agreement between MRI and arthroscopic findings (kappa rate = 0.54). Multiple logistic regression analysis demonstrated that a tibia vara angle > 3 was associated with a 5.2-fold increase (95% CI 0.99-27.01; p = 0.050), and a tibial slope > 12 with a 5.4-fold increase (95% CI 1.03-28.19; p = 0.046) in LMPRTs. CONCLUSIONS: Patients with greater tibia varus angles, increased tibial slopes, and higher BMIs were found to have an increased risk of LMPRTs when sustaining an ACL rupture. There was a low rate of agreement between MRI and arthroscopy in identifying LMPRTs. In patients with ACL ruptures who have abnormal tibial alignment or increased BMI, physicians should be watchful for lateral meniscus posterior root tears. LEVEL OF EVIDENCE: 3.

Impact of ball weight on medial elbow torque in youth baseball pitchers.

HYPOTHESIS: Our hypothesis was that an increase in ball weight would result in an increase in medial elbow torque during the pitching motion. METHODS: Youth pitchers were recruited for this study and instructed to throw 5 maximum-effort fastballs from ground level using baseballs of 4 different weights: 85 g (3 oz), 113 g (4 oz), 142 g (5 oz), and 170 g (6 oz). The validated Motus sensor was used to assess medial elbow torque, arm speed, arm slot, and shoulder rotation for each pitch. Pitch velocity was measured using a radar gun. Relationships between baseball weight and pitching kinetics and/or kinematics were evaluated using linear mixed-effects analysis. An exit survey was conducted detailing the pitcher's evaluation of the ball weights used. RESULTS: A total of 19 youth baseball pitchers (average age, 11.8 ± 1.1 years; age range, 9-14 years) completed the study. For every 1-oz (28-g) increase in ball weight, ball velocity decreased 2.0 ± 0.1 mph (χ2 = 52.68, P < .001), medial elbow torque increased 0.92 ± 0.37 newton meters (χ2 = 5.36, P = .02), and arm speed decreased 8.52 ± 3.68 rpm (χ2 = 5.03, P = .02). Shoulder rotation and arm slot were not significantly impacted by ball weight (P > .05). Survey results indicated that the 85-g (3-oz) baseball was most favored (8 of 19 pitchers) and believed to result in the highest pitch velocity (15 of 19 pitchers). The 170-g (6-oz) baseball was least favored (17 of 19 pitchers) and believed to result in the slowest pitch velocity (18 of 19 pitchers). No adverse outcomes were reported with the use of any ball weight or the mobile sensor. CONCLUSION: Among youth pitchers, an increase in ball weight correlated with greater medial elbow torque, decreased pitch velocity, and decreased arm speed.

Implications of Core and Hip Injuries on Major League Baseball Pitchers on the Disabled List.

PURPOSE: To investigate the frequency of core and hip injuries in Major League Baseball (MLB) pitchers and their impact on performance, workload, and pitch type. METHODS: Demographic, performance data, and injury data were acquired for 330 MLB pitchers with 454 injuries placed on the disabled list (DL) from 2014 to 2015 seasons. Core and hip/groin injuries were analyzed in which injury year data were compared with career data and against other injury groups. RESULTS: Core injuries represented 14% of all injuries and hip/groin injuries represented 7%. Average days on the DL for core injuries were 47.0 (standard deviation 5.6) days and 37.7 (standard deviation 8.1) days for hip/groin injuries. Return from the DL the same season for core injuries was 78% and 73% for hip/groin injuries. Core injuries returned to the DL 46% of the time (73% for noncore injuries) and hip/groin returned 56% of the time (60% for nonhip/groin injuries). No changes in workload were noted except starters with core injuries pitched less innings/game (5.3 vs 4.9 innings/game, P = .031) and more pitches/game (85.5 vs 78.4 pitches, P = .026). Fastball velocity decreased in the core injury group the year of injury (91.6 vs 92.2 mph, P = .001). Core injuries had slightly fewer home runs/9 innings and fewer strikeouts/9 innings; hip/groin injuries had slightly more strikeouts/9 innings, with all other performance statistics no different between the groups including earned run average and wins above replacement. CONCLUSIONS: Core and hip injuries in MLB pitchers result in similar time on the DL compared with other injuries. Pitching workload during the year of injury does not seem to have a significant impact on sustaining a core or hip injury. Although there is a high rate of return to play from the DL, there is a high rate of reinjury in these pitchers more often for other injuries. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
