RESUMO
BACKGROUND: Orthopaedic surgery in the U.S. historically has been among the least demographically diverse specialties in medicine. Currently, limited data exist on how patients perceive diversity within the field and what patients look for when choosing an orthopaedic surgeon. The purpose of this study was to identify specific patient preferences for surgeon demographics and understand patient perceptions of racial and gender diversity in orthopaedic surgery. METHODS: Nonconsecutive patients from orthopaedic clinics affiliated with a U.S. academic health system voluntarily completed a 39-item questionnaire that surveyed basic demographic information, perception of diversity, racial and gender preferences during surgeon selection, and perception of health-care inequalities. Bivariate analyses were used to test the association between patient-surgeon demographic variables and ratings of diversity. Multiple regression models were used to identify independent predictors of overall perceived diversity ratings. RESULTS: A total of 349 patients (80.6% White, 17.9% Black, and 1.5% other) were analyzed. Black patients were more likely to experience difficulty relating to their surgeon than White patients (11.48% versus 2.29%; odds ratio [OR], 5.62; 95% confidence interval [CI], 1.55 to 21.1; p = 0.004). Moreover, Black patients were more likely to perceive racial bias from their surgeon than White patients (5.17% versus 0.37%; OR, 14.44; 95% CI, 1.14 to 766.29; p = 0.02). While the level of racial diversity perceived by White patients (2.57 of 10) was significantly higher than that perceived by Black patients (2.10 of 10) (p = 0.001), the absolute difference between these 2 figures was small, suggesting that both groups perceived racial diversity in orthopaedics to be low. White and Black patients differed in their importance ranking of a surgeon's race (p < 0.0001): Black patients ranked a surgeon's race with higher importance (mean, 3.49 of 10) when selecting a surgeon compared with White patients (1.45 of 10). Both male and female patients gave relatively low importance rankings for a surgeon's gender (mean, 1.58 of 10 and 2.15 of 10, respectively, p = 0.02). CONCLUSIONS: Patients in this study did not perceive orthopaedic surgery as a diverse field (overall diversity rating, <3 of 10). There were significant racial and gender differences in patients' preferences for specific physician characteristics when choosing an orthopaedic surgeon, which may help explain some instances of perceived racial bias and difficulty relating to their orthopaedic surgeon.

The coronavirus disease 2019 (COVID-19) pandemic has enabled the adoption of digital health platforms for self-monitoring and diagnosis. Notably, the pandemic has had profound effects on athletes and their ability to train and compete. Sporting organizations worldwide have reported a significant increase in injuries manifesting from changes in training regimens and match schedules resulting from extended quarantines. While current literature focuses on the use of wearable technology to monitor athlete workloads to guide training, there is a lack of literature suggesting how such technology can mediate the return to sport processes of athletes infected with COVID-19. This paper bridges this gap by providing recommendations to guide team physicians and athletic trainers on the utility of wearable technology for improving the well-being of athletes who may be asymptomatic, symptomatic, or tested negative but have had to quarantine due to a close exposure. We start by describing the physiologic changes that occur in athletes infected with COVID-19 with extended deconditioning from a musculoskeletal, psychological, cardiopulmonary, and thermoregulatory standpoint and review the evidence on how these athletes may safely return to play. We highlight opportunities for wearable technology to aid in the return-to-play process by offering a list of key parameters pertinent to the athlete affected by COVID-19. This paper provides the athletic community with a greater understanding of how wearable technology can be implemented in the rehabilitation process of these athletes and spurs opportunities for further innovations in wearables, digital health, and sports medicine to reduce injury burden in athletes of all ages.
RESUMO
Purpose: The purpose of this study was to determine the rates of concomitant knee pathology in patients with ACL injuries and Segond fractures. Methods: A retrospective study is undertaken with patients identified via query of CPT codes for ACL reconstruction from 2014 to 2020. All patients with preoperative radiographs were reviewed for the presence of Segond fractures. Operative reports were analyzed for the presence of concurrent pathology, including meniscus, cartilage, and other ligamentous injuries at the time of arthroscopic ACL reconstruction. Results: A total of 1,058 patients were included in the study. Segond fractures were identified in 50 (4.7%) patients. Ipsilateral concomitant knee pathology was identified in 84% of Segond patients. Thirty-eight (76%) patients had meniscal pathology with a total 49 meniscal injuries, of which 43 were treated operatively. Multiligamentous injuries were present in 16 patients (32%), with 8 patients undergoing further ligament repair/reconstruction at the time of surgery. Chondral injuries were identified in 13 patients (26%). Conclusions: A high prevalence of concomitant meniscal, chondral, and ligamentous injuries was found in patients with Segond fractures. These additional injuries may require further operative management and may place patients at increased risk for future instability or degenerative changes. Patients with Segond fractures should be counseled preoperatively on the nature of their injuries and risk of associated pathologies. Level of Evidence: Level IV, prognostic case series.
RESUMO
INTRODUCTION: Successful outpatient anterior cruciate ligament (ACL) reconstruction hinges on effective analgesia. Routinely, oral narcotic agents have been the preferred analgesic postoperatively in orthopaedic surgery. However, these agents have several known adverse effects and are associated with a potential for abuse. This study evaluates the efficacy of ketorolac, a nonsteroidal anti-inflammatory drug with analgesic properties, as an adjuvant agent for postoperative pain control after ACL reconstruction. METHODS: Adult patients undergoing primary ACL reconstruction were prospectively enrolled. Exclusion criteria involved patients with a history of bleeding diathesis, renal dysfunction, chronic analgesia use, or alcohol abuse. Eligible patients were randomized into one of two groups. The control group received a standard-of-care pain protocol involving oxycodone-acetaminophen 5 to 325 on discharge. The ketorolac group additionally received intravenous ketorolac postoperatively and 3 days of oral ketorolac on discharge. Pain levels and total narcotic utilization were recorded three times per day for the first 5 days after surgery. Pain and functional outcomes were obtained at 2 and 6 weeks postoperatively. RESULTS: The final analysis included 48 patients; the mean age of the cohort was 32 ± 11.6 years, and 60.4% of patients were female. No differences were observed in preoperative demographics, comorbidities, and preoperative functional scores between the two groups. Over the first 5 days after surgery, patients in the ketorolac group consumed a mean of 45.4% fewer narcotic pills than the control group (P < 0.001). In addition, mean postoperative pain scores were 22.36 points lower for patients in the ketorolac group (P < 0.001). There was no difference in functional outcome scores at up to 6 weeks postoperatively or adverse events between the two groups with no reported cases of gastrointestinal bleeding. DISCUSSION: The use of adjunctive intravenous and short-term oral ketorolac substantially reduces narcotic utilization and pain levels after ACL reconstruction.

BACKGROUND: The anterolateral complex has been demonstrated to assist with rotational stability and prevention of anterior tibial translation during the pivot shift. In this study the Segond fracture is used as a surrogate for an anterolateral complex injury to determine if there is an association between Segond fracture and increased posterior tibial slope. METHODS: Patients' charts and radiographs were analyzed retrospectively for the presence of Segond fractures on injury radiographs. These patients, the Segond cohort, were then age and gender matched to a control cohort. Demographic as well MRI measurements of medial and lateral posterior tibial slope and lateral-to-medial slope asymmetry were collected for each cohort. Secondary outcome of anterior cruciate ligament reconstruction failure data was also collected. RESULTS: The Segond group demonstrated a statistically significantly greater lateral posterior tibial slope (8.42° versus 6.55°, P = 0.003) as well as medial posterior tibial slope (6.57° versus 5.34° degrees, P = 0.045). There was no significant differences between lateral-to-medial asymmetry (2.18°versus 1.83°, P = 0.246). CONCLUSION: Patients with Segond fractures at the time of anterior cruciate ligament injury have increased medial and lateral posterior tibial slope. This may relate to increased rotational and translational instability associated with anterolateral complex injuries. Surgeons treating these patient may use this information to counsel their patients on the risks of associated pathology at the time of arthroscopy such as lateral meniscal posterior root tears.

Background: Major League Baseball (MLB) adopted a rule change in 2016 to reduce the number of collisions that occur when a player slides into a base. The effect of rule 6.01(j) has not been quantified, and it remains unknown if this rule change has led to improved player safety. Hypothesis: Rule 6.01(j) would be associated with a reduction in the number of collision-related injuries at second base. Study Design: Cohort study; Level of evidence, 3. Methods: Using data from the MLB Health and Injury Tracking System, we quantified the number of collision-related injuries for defensive (ie, fielding) players in the infield at the major and minor league levels between the 2010 and 2019 seasons. We compared the median number of collision-related injuries for defensive players in the infield from before (2010-2015) to after (2016-2019) the implementation of rule 6.01(j) and also calculated the difference in location of the median from the seasons before versus after the rule change. An additional 3 analyses were performed to support or contradict a conclusion that any observed reduction in injuries at the start of the 2016 season was likely caused by the adoption of rule 6.01(j). Results: The median number of collision-related injuries for defensive players at second base decreased from 58.5 to 37.5 injuries per season after the rule change, which was a 36% decrease (difference in location, 19.5 [95% CI, 5.0 to 31.0]; P = .019). In contrast, the median number of collision-related injuries at first base decreased by only 14.1%, from 49.5 before to 42.5 after the rule change (difference in location, -9.0 [95% CI, -4.0 to 18.0]; P = .16), and the median number of collision-related injuries per season at third base was unchanged at 15 per season. Conclusion: This rule change was associated with a decrease in the number of collision-related injuries, with the largest effect observed at second base, as expected.
RESUMO
Background and objective Primary patellar dislocations can concomitantly involve osteochondral injuries for which prompt recognition is paramount for joint preservation. These injuries can be missed on radiographs, necessitating MRI examinations. In this study, we aimed to identify patient parameters that correlate with occult osteochondral injuries. Methods Patients were retrospectively identified between 2015 and 2020 through a chart review. The inclusion criteria were as follows: patients diagnosed with a primary patellar dislocation with three radiographic views and an MRI of the injured knee. Demographic and radiographic data were evaluated. Results A total of 61 patients met the inclusion criteria. There were no statistically significant demographic differences between patients with osteochondral injuries and those without (p>0.05). Seven knees (88%) with an osteochondral lesion and 20 (38%) without had an effusion (p=0.02). There was no association in terms of ligamentous laxity (p=0.49), Caton-Deschamps index (CDI) (p=0.68), sulcus angle (SA) (p=0.68), congruence angle (CA) (p=0.56), and lateral patellofemoral angle (LPFA) (p=0.25) between patients with and without an occult osteochondral injury. Conclusion Among the parameter examined, the presence of an effusion was the only one that correlated with the presence of occult osteochondral injury in our cohort.
RESUMO
BACKGROUND: Few studies have compared clinical outcomes between the traditional Latarjet procedure for anterior shoulder instability and the congruent arc modification to the Latarjet procedure. PURPOSE: To systematically evaluate the literature for the incidence of recurrent instability, clinical outcomes, radiographic findings, and complications for the traditional Latarjet procedure and the congruent arc modification and to compare results of each search. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review and meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We included studies published between January 1990 and October 2020 that described clinical outcomes of the traditional Latarjet and the congruent arc modification with a follow-up range of 2 to 10 years. The difference in surgical technique was analyzed using a chi-square test for categorical variables, while continuous variables were evaluated using a Student t test. RESULTS: In total, 26 studies met the inclusion criteria: 20 studies describing the traditional Latarjet procedure in 1412 shoulders, and 6 studies describing the congruent arc modification in 289 shoulders. No difference between procedures was found regarding patient age at surgery, follow-up time, Rowe or postoperative visual analog scores, early or late complications, return-to-sport timing, or incidence of improper graft placement or graft fracture. A significantly greater proportion of male patients underwent glenoid augmentation using the congruent arc modification versus traditional Latarjet (P < .001). When comparing outcomes, the traditional Latarjet procedure demonstrated a lower incidence of fibrous union or nonunion (P = .047) and broken, loose, or improperly placed screws (P < .001), and the congruent arc modification demonstrated improved outcomes with regard to overall return to sport (P < .001), return to sport at the same level (P < .001), incidence of subluxation (P = .003) or positive apprehension (P = .002), and revision surgery for recurrent instability (P = .027). CONCLUSION: Outcomes after the congruent arc modification proved at least equivalent to the traditional Latarjet procedure in terms of recurrent instability and return to sport, although early and late complications were equivalent. The congruent arc procedure may be an acceptable alternative to traditional Latarjet for the treatment of anterior shoulder instability with glenoid bone loss; however, long-term outcomes of this procedure are needed.
RESUMO
BACKGROUND: Arthroscopic rotator cuff repair (RCR) is associated with substantial postoperative pain. Oral narcotic agents are the preferred analgesic postoperatively. However, these agents are associated with several side effects and a potential for abuse. This study evaluates the efficacy of ketorolac as an adjunctive agent for postoperative pain control after arthroscopic RCR. METHODS: Adult patients undergoing arthroscopic RCR were prospectively enrolled and randomized to one of two groups. The control received our institution's standard-of-care pain protocol, including oxycodone-acetaminophen 5 to 325 mg on discharge. The ketorolac group received the standard-of-care protocol, intravenous ketorolac at the completion of the procedure, and oral ketorolac on discharge. Pain and functional outcome scores and narcotic utilization were recorded three times per day for the first 5 days after surgery. Repeat magnetic resonance imaging was done at least 6 months postoperatively. RESULTS: In our study, 39 patients were included for final analysis; the mean age of the cohort was 55.7 ± 10.6 years, and 66.7% of patients were male. No differences were observed in preoperative demographics, comorbidities, cuff tear morphology, and functional scores between the two groups. Over the first 5 days after surgery, patients in the ketorolac group consumed a mean of 10.6 fewer narcotic pills, a consumption reduction of 54.6% (19.42 versus 8.82, P < 0.001). No difference was observed in functional outcome scores at up to 6 weeks postoperatively between the two groups. No difference was observed in adverse events between the two groups with no reported cases of gastritis or gastrointestinal bleeding. Twenty-two of 39 patients underwent repeat magnetic resonance imaging at a mean of 7.9 months postoperatively, of which 5 (22%) demonstrated a retear of their rotator cuff. No significant difference was observed between the ketorolac and control groups in the rate of retear (P = 1.00). DISCUSSION: Adjunctive ketorolac substantially reduces narcotic utilization after arthroscopic RCR.

CONTEXT: There is currently no evidence-based consensus on how to treat a full-thickness, symptomatic articular cartilage injury of the patella, although numerous treatment options are available. OBJECTIVE: To systematically evaluate the functional outcomes after operative treatment of patellar cartilage lesions. Our secondary purpose was to evaluate radiographic outcomes after treatment. DATA SOURCES: PubMed, Cochrane, and Embase. STUDY SELECTION: Studies published between January 1, 1990 and December 31, 2018 that included patient-reported functional outcomes for patients after operative treatment of patellar chondral defects at a minimum 2-year follow-up were included. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: MINORS (Methodological Index for Non-Randomized Studies) score, level of evidence, sample size, demographic data, follow-up data, intervention, functional outcome scores, and magnetic resonance imaging (MRI) data were collected. RESULTS: The review identified 10 studies and 293 patients receiving cartilage restoration procedures for patellar chondral defects with extractable clinical and radiographic results and data on complications and reoperations. All treatments (autologous chondrocyte implantation [ACI], matrix-induced ACI [MACI], autologous osteochondral transplantation [AOT]) utilized in the management of patellar chondral lesions, with the exception of isolated particulated juvenile articular cartilage, demonstrated statistically significant improvements in functional outcome scores compared with preoperative measurements at a minimum of 2-year follow-up. Postoperative MRIs were obtained in 6 studies and found that regardless of treatment, moderate-to-complete infill of patellar cartilage lesions was seen in the majority of patients. While failure rates were low for the various treatment modalities, rates of reoperation were substantial, with up to 40% to 60% reoperation rate seen after ACI. CONCLUSION: Patients treated with ACI, MACI, and AOT all demonstrated statistically significant improvements in functional outcome scores with radiographic evidence of healing at minimum of 2-year follow-up. Evidence is insufficient to recommend one particular treatment over another.

BACKGROUND: In patients on warfarin anticoagulation therapy, elective shoulder arthroplasty surgeons must carefully balance bleeding and embolic risks. Currently, an international normalized ratio (INR) threshold of 1.5 is supported in the setting of elective surgery. However, no previous study has investigated the optimal preoperative INR target specifically in shoulder arthroplasty. The purpose of this study was to evaluate the association of preoperative INR with rates of transfusion, complication, and readmission/revision surgery in shoulder arthroplasty. METHODS: Patients who underwent elective shoulder arthroplasty were identified in a national database. The primary outcome of interest was the risk for all-cause complication at 30 days postoperatively. Major and minor complication, revision surgery, and readmission rates were also investigated. RESULTS: From 2006 to 2016, 1,014 procedures were identified who had undergone elective shoulder arthroplasty with a perioperative INR lab result within 24 hours of surgery. In our cohort, 550 patients (54.2%) were women, with an average age of 71.0 ± 9.8 years. After controlling for confounders, patients with a preoperative INR > 1.5 were 18.9 times as likely to have a major complication as those with a preoperative INR ≤ 1.0 (P = 0.003). Patients with an INR of 1.25 < INR ≤ 1.5 did not have a statistically significant risk of minor or major complication in comparison with those with an INR ≤ 1.0 (P = 0.23, P = 0.67). DISCUSSION: Although recent hip and knee arthroplasty literature has found that an INR < 1.25 may be an optimal preoperative INR goal, our results did not find an increased risk for bleeding and complication with an INR ≤ 1.5 for shoulder arthroplasty. These results support current guidelines recommending a preoperative INR ≤ 1.5 for shoulder arthroplasty.

BACKGROUND: Although the achievement of adequate analgesia is critical to patient comfort and recovery following orthopedic procedures, no standard protocol exists to dictate the appropriate duration and quantity of narcotic prescription in the postoperative period. Therefore, the purpose of this survey was to determine patterns of opioid prescribing among orthopedic shoulder and elbow providers. METHODS: In March 2020, a survey was distributed through a LISTSERV to 989 members of the American Shoulder and Elbow Surgeons orthopedic society. Survey recipients were asked to describe their personal and practice characteristics. Additionally, they were asked to list their 3 most commonly performed procedures and, for each operation, to list which narcotic pain medication they most commonly prescribe postoperatively, along with the corresponding number of tablets typically given. Similarly, respondents were asked to record frequently recommended alternative strategies for postoperative pain control, factors influencing the respondents' prescribing practices, and methods of patient counseling regarding opioid use and disposal. RESULTS: A total of 177 providers responded to the survey. Across all selected procedures, Percocet (5 mg of oxycodone hydrochloride and 325 mg of acetaminophen) was the most commonly prescribed drug, with 21-30 tablets being the most commonly prescribed amount. The majority of surgeons (82%) indicated that previous opioid prescriptions influence their decision to prescribe opioids. Respondents most frequently reported patient age (48%) and duration of the patient's symptoms (32%) as additional influential factors. Most surgeons (93%) reported counseling their patients regarding the use of opioid medications. However, only 30% of surgeons reported providing information regarding how to dispose of unused opioids. In lieu of opioids, nearly all investigators reported the use of ice as a pain-relief strategy, with rest and the use of nonsteroidal anti-inflammatory drugs reported as other commonly recommended alternatives. Of 137 respondents who were aware of prescription guidelines, 21% reported using recommendations from the American Academy of Orthopaedic Surgeons, 21% used institutional policies, and 20% used personal guidelines, whereas the remaining respondents used other literature findings in their prescription decisions. Of particular concern, 21% of overall respondents were unaware of any type of guidelines. DISCUSSION: To prevent both misuse and abuse of opioid prescribing, this analysis serves as a starting point for the establishment of more consistent, evidence-based opioid prescription guidelines for surgical procedures on the shoulder and elbow. In addition to recommending safe, procedure-specific opioid dosages and standardizing pain management strategies, these guidelines should include effective methods of educating both providers and patients regarding the use of opioid medication.

PURPOSE: To evaluate whether a narrow posterior joint space (<2 mm) correlated with posterior joint cartilage degeneration in the hip preservation patient population. METHODS: A retrospective chart review of 155 consecutive hip arthroscopy cases by a single surgeon (SKA) from March 2012 to February 2013 was performed. Patients were included in the study if they had an adequate perioperative false profile radiograph and clear intraoperative arthroscopic images of the posterior hip joint. The narrowest posterior joint space (NPJS) width and the directly posterior, posterosuperior, superior, and anterosuperior joint space widths were measured on the false profile radiograph. Femoral and acetabular cartilage of the posterior hip joint were graded according to the International Cartilage Repair Society (ICRS) classification system using arthroscopic images obtained at the time of surgery. The cartilage grades of patients with <2 mm NPJS were compared with cartilage grades of patients with ≥2 mm NPJS. RESULTS: There was no difference in cartilage grading between patients with <2 mm NPJS (19 patients) and those with ≥2 mm NPJS (81 patients) (P = .905). The mean age of patients with NPJS ≥2 mm and <2 mm was 34.0 (median 31.2; interquartile range [IQR] 23.7, 42.9) and 38.7 (median 43.0; IQR 26.1, 50.9) respectively, and was not statistically different (P = .183). No correlation between cartilage grade and NPJS measurement was found (P = .374). CONCLUSION: In this predominantly cam-type femoroacetabular impingement patient cohort, our findings indicate there is no correlation between a <2 mm posterior hip joint narrowing seen on false profile radiographs and posterior hip cartilage degeneration confirmed with arthroscopy. Although posterior arthritis can be visualized on a false profile radiograph, a posterior joint space measurement <2 mm should not be interpreted as isolated posterior joint wear and should not be considered a hip arthroscopy contraindication. LEVEL OF EVIDENCE: Level IV, case series.

PURPOSE OF REVIEW: The purpose of this review is to discuss relevant anatomy and pathoanatomy in the knee following anterior cruciate ligament reconstruction, risk factors for contralateral ACL tear, and mechanisms of contralateral injuries in the pediatric population. RECENT FINDINGS: Contralateral ACL rupture rates following ACL reconstruction (ACLR) range from 4% to 42%. Pediatric patients show increased risk compared with adults, likely due to inherent anatomical differences along with biomechanical and neuromuscular changes that occur in both the operative and contralateral knees following index ACLR. Pediatric athletes who return to sport more quickly have been found to be at increased risk for contralateral tears, as have athletes who participate in cutting and pivoting sports. Contralateral tears tend to occur via non-contact mechanisms. Pediatric patients are at increased risk of contralateral ACL injury following index ACL reconstruction compared with adults. Further study is warranted to determine appropriate biologic, functional, and rehabilitative parameters gauged toward preventing contralateral ACL tear while minimizing time lost from sport.
RESUMO
PURPOSE: To systematically review the literature to better understand the technique, outcomes, and complications after percutaneous superficial medial collateral ligament (sMCL) lengthening during knee arthroscopy to address isolated medial meniscal pathology. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines using a PRISMA checklist. The inclusion criteria consisted of English-language articles or articles with English-language translations documenting the use of percutaneous sMCL lengthening during arthroscopic knee surgery to treat isolated meniscal pathology (repair vs meniscectomy) with reported postoperative outcomes and complications. RESULTS: Four studies met the inclusion criteria, consisting of a total of 192 patients undergoing percutaneous sMCL lengthening. No perioperative complications related to iatrogenic chondral damage, fracture, or additional meniscal injury were reported. Mild postoperative pain at the medial needle tract site lasting up to 15 days after surgery was reported in 52% of patients (46 of 88). At final follow-up, laxity on valgus stress testing showed a range from 0 to 1.1 mm with a range from -0.3° to 0.9° of radiographic medial joint space widening compared with preoperative radiographs. The length of follow-up ranged from 1.5 to 24 months. CONCLUSIONS: The percutaneous "pie-crusting" technique remains the most commonly reported technique to lengthen the sMCL during arthroscopic meniscal surgery. Percutaneous lengthening represents a safe and effective method of increasing medial joint space visualization, with no reported perioperative or postoperative complications and with minimal, likely clinically insignificant residual joint laxity after surgery on valgus stress testing at final follow-up compared with preoperative values. LEVEL OF EVIDENCE: Level IV, systematic review of Level IV studies.
RESUMO
¼ Injuries to the posterior root of the lateral meniscus occur frequently in acute knee injuries with concomitant tearing of the anterior cruciate ligament (ACL). ¼ The meniscofemoral ligaments (MFLs), consisting of the anterior MFL (ligament of Humphrey) and the posterior MFL (ligament of Wrisberg), as well as the osseous attachment of the meniscal root, stabilize the lateral meniscus, enabling appropriate load transmission and maintenance of contact forces within the lateral compartment of the knee during loading and range of motion. ¼ In the setting of an ACL injury to the knee with osseous root injury of the posterior root of the lateral meniscus, the MFLs (when present) may stabilize the lateral meniscus against meniscal extrusion, thereby maintaining appropriate contact mechanics within the knee, decreasing the risk of subsequent chondral and meniscal injury and the development of premature osteoarthritis. ¼ Additional study on the indications for posterior meniscal root repair during ACL reconstruction is warranted since the ideal management of lateral root injury in the MFL-intact knee remains unknown.

CASE: A 47-year-old man with an isolated femoral neck fracture was treated with open reduction and internal fixation with a medial femoral neck buttress plate and a dynamic hip screw. Union was achieved without osteonecrosis of the femoral head. However, hip arthroscopy that was performed for persistent hip pain following the fracture union revealed an intra-articular impingement of the buttress plate and a substantial anterior acetabular chondral injury. CONCLUSIONS: To our knowledge, this is the first reported complication associated with the application of a medial buttress plate for a femoral neck fracture. This case report may help surgeons who employ this technique to avoid a similar complication.

BACKGROUND: Distraction of the hip joint is a necessary step during hip arthroscopic surgery. The force of traction needed to distract the hip is not routinely measured, and little is known about which patient factors may influence this force. PURPOSE: To quantify the force of traction required for adequate distraction of the hip during arthroscopic surgery and explore the relationship between hip joint stiffness and patient-specific demographics, flexibility, and anatomy. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 101 patients (61 female) undergoing primary hip arthroscopic surgery were prospectively enrolled. A load cell attached to the traction boot continuously measured traction force. Fluoroscopic images were obtained before and after traction to measure joint displacement. The stiffness coefficient was calculated as the force of traction divided by joint displacement. Relationships between the stiffness coefficient and patient demographics and clinical parameters were investigated using a univariable regression model. The regression analysis was repeated separately by patient sex. Variables significant at P < .05 were included in a multivariable regression model. RESULTS: The instantaneous peak force averaged 80 ± 18 kilogram-force (kgf), after which the force required to maintain distraction decreased to 57 ± 13 kgf. In univariable regression analysis, patient sex, alpha angle, hamstring flexibility, and Beighton hypermobility score were each correlated to stiffness. However, patient sex was the only significant variable in the multivariable regression model. Intrasex analysis demonstrated that increased hamstring flexibility correlated with decreased final holding stiffness in male patients and that higher Beighton scores correlated with decreased maximal stiffness in female patients. CONCLUSION: Male patients undergoing primary arthroscopic surgery have greater stiffness to hip distraction during arthroscopic surgery compared with female patients. In male patients, stiffness increased with decreasing hamstring flexibility. In female patients, increased Beighton scores corresponded to decreased stiffness. The presence of a labral tear was not correlated with stiffness to distraction. These data may be used to identify patients in whom a specific focus on capsular repair and/or plication may be warranted.
