RESUMO
PURPOSE: To determine whether response to preoperative local anesthetic or corticosteroid intra-articular injections can predict 2-year postoperative outcomes in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). METHODS: This was a retrospective analysis of patients undergoing hip arthroscopy for FAIS at a single institution from 2014-2020. Patients who underwent preoperative intra-articular hip injection were classified based on injection type (local anesthetic, corticosteroid) and whether they experienced pain relief following injection (responders, non-responders). Responders were matched 2:1 by age, BMI, and sex with non-responders. Patient reported outcomes (PROs) including Hip Disability and Osteoarthritis Outcome Score (HOOS), 12-item Short-Form Survey mental (SF-12-MCS) and physical component summary (SF-12-PCS) and visual analogue scale (VAS) pain were collected preoperatively and 2-years postoperatively. Mean score change and Minimal Clinically Important Difference (MCID) achievement were calculated and compared between groups. RESULTS: The matched cohort included 126 total patients (42 non-responders, 84 responders; 74.6% female; mean ± SD age: 30.9 ± 9.9 years; BMI: 24.7 ± 3.7 kg/m2) with no differences in demographic or radiographic hip variables. Both groups demonstrated significant 2-year postoperative score improvements across all PROs, except SF-12-MCS, which remained unchanged. There was no difference in mean score change or MCID achievement across all PROs between corticosteroid injection responder and non-responder groups. In the local anesthetic group, MCID achievement was similar across all PROs, except VAS pain which showed greater percentage of MCID achievement among local anesthetic non-responders relative responders (Responders: 55.0%, Non-responders: 89.5%; p = 0.03). Significant ceiling effects were most readily apparent among the injection responders group with greater percentages of patients achieving maximal 2-year postoperative survey scores (36.9% HOOS-ADL, 19.0% HOOS-Pain, 15.5% HOOS-QoL, 32.1% HOOS-Sport). CONCLUSIONS: Response to preoperative injection with either corticosteroid or local anesthetic did not predict 2-year outcomes after hip arthroscopy in patients with FAIS. LEVEL OF EVIDENCE: Level III, retrospective matched cohort study.
RESUMO
Purpose: To analyze the annual use of hip arthroscopy (HA) and Bernese periacetabular osteotomy (PAO) for the treatment of hip dysplasia (HD), as well as postoperative outcomes, including ipsilateral reoperations. Methods: International Classification of Diseases, Ninth and Tenth Revision, codes were used to query the PearlDiver Mariner database from January 2010 through January 2022 to identify patients aged 10 to 59 years who had a presenting diagnosis of HD and subsequently underwent (1) HA; (2) PAO; or (3) combined HA and PAO (HA-PAO, defined as PAO on the same day or within 28 days after HA). We analyzed annual rates for each treatment, as well as rates of postoperative emergency visits, readmissions, and 5-year ipsilateral secondary operations (determined via Kaplan-Meier analysis). Results: There were 32,068 patients who underwent surgical treatment of HD. For HA, PAO, and HA-PAO, there were 29,700, 2,083, and 285 patients, respectively. All operations had the greatest percent-increase from 2015 to 2016. HA and HA-PAO peaked in 2021, whereas PAO peaked in 2019. For HA, PAO, and HA-PAO, most cases were performed in female patients and patients aged 30 to 49 years, 10 to 19 years, and 10 to 29 years, respectively. The 5-year incidence of ipsilateral secondary operations, which include revision HA, PAO, or conversion to total hip arthroplasty, was 9.2% (95% confidence interval 8.6%-9.8%) in the HA group and 6.5% (95% confidence interval 4.1%-8.8%) in the PAO group. Combining HA with PAO resulted in so few secondary operations that Kaplan-Meier analysis was infeasible. The PAO cohort had the greatest 30-day emergency visit and 90-day readmission rates, with infection as the most common cause for readmission. Conclusions: HA is more frequently performed than PAO for hip dysplasia. HA-PAO is increasing at the greatest rate, demonstrating fewer complications and reoperations. Level of Evidence: Level III, retrospective comparative trial.
RESUMO
PURPOSE: To evaluate a large cross-sectional sample of patients utilizing administrative database records and analyze the effects of income, insurance type, and education level on outcomes after hip arthroscopy, including 2-year revision surgery, conversion to total hip arthroplasty (THA), and 90-day hospitalizations. METHODS: Current Procedural Terminology codes were used to query the PearlDiver Mariner database from October 2015 to January 2020 for patients undergoing hip arthroscopy with a minimum 2-year follow-up. Patients were categorized by mean family income in their zip code of residence (MFIR), health insurance type, and educational attainment in their zip code of residence (EAR). Two-year revision arthroscopy, conversion to THA, and 90-day hospital readmissions or emergency department (ED) visits were analyzed along socioeconomic strata. RESULTS: Multivariate analysis of 33,326 patients revealed that patients with MFIR between $30,000 and $70,000 had lower odds of 2-year revision arthroscopy (odds ratio [OR], 0.63; P < .001), THA conversion (OR, 0.76; P = .050), and 90-day readmission (OR, 0.53; P = .007) compared to MFIR >$100,000. Compared to patients with commercial insurance, patients with Medicare had lower odds of revision arthroscopy (OR, 0.60; P = .035) and THA conversion (OR, 0.46, P < .001) but greater odds of 90-day readmission (OR, 1.74; P = .007). Patients with Medicaid had higher odds of 90-day ED visits (OR, 1.84; P < .001). Patients with low EAR had higher odds of revision arthroscopy (OR, 1.42; P = .005) and THA conversion (OR, 1.58; P = .002) compared to those with high EAR. CONCLUSIONS: Following hip arthroscopy, patients residing in areas with lower mean family income were less likely to undergo reoperations and readmissions. Medicare patients showed lower reoperation but higher readmission odds, while Medicaid patients showed higher odds of ED visits. Additionally, higher educational attainment in the zip code of residence is protective against future reoperation. LEVEL OF EVIDENCE: Level III, retrospective case series.
RESUMO
INTRODUCTION: Sex disparities in presentation of osteoarthritis and utilization of joint replacement surgery (JRS) have been demonstrated. The role of patients' unique perspectives on JRS on their treatment decisions is poorly understood. METHODS: JRS candidates who were offered JRS but declined surgical treatment completed this survey. Survey questions included demographic information, patient experiences and current opinions around JRS, patient experiences with providers, goals and concerns, and barriers to JRS. RESULTS: More women experience barriers to undergoing JRS compared with men (53% versus 16%; P = 0.014). While both men and women indicated pain relief as their primary goal for treatment, women were significantly more likely to prioritize regaining the ability to complete daily tasks and responsibilities when compared with men (P = 0.007). Both men and women indicated that low symptom severity and nonsurgical treatment options were the reasons for not undergoing JRS (P = 0.455). Compared with men, women trended toward feeling that they were not sufficiently educated about JRS (P = 0.051). CONCLUSION: Women have unique perspectives and goals for JRS that may pose sex-specific barriers to care. A better understanding of how patients' gendered experiences affect their decision making is necessary to improve treatment of osteoarthritis and decrease disparities in care.

Introduction: In recent years, the utilization of hip arthroscopy to treat femoroacetabular impingement syndrome (FAIS) has increased due to its low complication rates, positive impact on patient-reported outcomes (PROs), and association with faster rehabilitation. Despite this, there are high rates of revision and conversion to total hip arthroplasty (THA) in some of these patients. It is unclear whether time from initial FAIS diagnosis to surgery is a risk factor for poor outcomes. In this study, we examined the relationship between timing of hip arthroscopy for FAIS and rates of 2-year revision hip procedures, 2-year conversion to total hip arthroplasty (THA), post-operative medical complications, and opioid prescriptions. Methods: This is a retrospective cohort study utilizing the PearlDiver database. Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes were used to identify patients who had surgery for FAIS with minimum 2 years follow-up available. Patients were stratified by 3-month intervals into 5 groups based on time from diagnosis of FAIS to hip arthroscopy. Multivariate logistic regression was performed to determine factors independently associated with continued opiate use and subsequent surgeries. Results: A total of 14,677 patients were included in the study. The 2-year rate of revision hip arthroscopy was 4.2%. As time from diagnosis to surgery increased, even in multivariate regression analysis, there was a higher risk of filling an opioid prescription 90 days after surgery (P < 0.001). Regression analysis demonstrated that timing of surgery was not associated with 2-year revision hip arthroscopy or conversion to THA. Age, sex, obesity, and tobacco use were significant predictors of revision hip arthroscopy and conversion to THA (p < 0.001). Conclusion: There is no significant difference between timing of surgery for FAIS and odds of revision or conversion to THA. Prolonged opiate use after hip arthroscopy was significantly higher as duration from initial FAIS diagnosis to surgery increased. Age, sex, obesity, and tobacco use are significant predictors for revision, conversion to THA, and continued opiate prescriptions.
RESUMO
Purpose: To evaluate patient-reported outcomes and risk for rerupture after surgical treatment of proximal hamstring tendon ruptures using all-suture anchors and a unique postoperative bracing strategy. Methods: A retrospective review of a prospectively collected database was conducted of patients undergoing proximal hamstring repair or reconstruction from 2020 to 2022 at a tertiary, academic institution. Patients were included if they reached minimum 1-year follow-up and completed postoperative patient-reported outcomes. The surgical protocol for proximal hamstring repairs included all-suture anchors placed either in an open or endoscopic fashion in the ischial tuberosity. After surgery, all patients underwent an accelerated rehabilitation protocol, including 6 weeks touchdown weight-bearing in a hinged knee brace locked in extension for ambulation, allowing passive knee flexion to 90° while seated. Descriptive statistics were used to analyze the data. Results: Twenty-one patients were included (mean age 50.4 ± 9.5 years, body mass index 24.4 ± 3.5, 66.7% female). Lower Extremity Functional Scale score achieved postoperatively was 74.2 ± 7.5 (out of 80). Patients had minimal pain (mean visual analog scale pain score of 0.9 ± 1.2). 61.9% of patients were able to return to the same level of activity after based on Tegner score by 1 year. Postoperative Single Assessment Numeric Evaluation activity of daily living was 94.3 ± 8.3, and Single Assessment Numeric Evaluation Sports was 82.3 ± 19.0. Mean Short Form Survey (SF-12) postoperative scores were 51.6 ± 6.8 for SF-12 Physical Component Score and 53.9 ± 9.7 for Mental Component Score. 95.2% (20 of 21) patients were satisfied with their outcome. There were no reruptures, infections, or reoperations. One patient of 21 (4.8%) incurred a postoperative deep venous thrombosis, which was treated with therapeutic anticoagulation for 3 months. Conclusions: All-suture anchors for proximal hamstring repair with a unique accelerated postoperative rehabilitation and bracing protocol result in good outcomes and patient satisfaction with minimal risk of complications. Level of Evidence: Level IV, case series, therapeutic.
RESUMO
INTRODUCTION: Studies show that females have a higher prevalence of osteoarthritis, worse symptoms, but lower rates of joint replacement surgery (JRS). The reason for this remains unknown. METHODS: A database of JRS candidates was created for patients seen in 2019 at an academic center. Demographics, Kellgren-Lawrence grades, symptom duration, visual analogue pain score, Charlson Comorbidity Index, and nonsurgical treatments were collected. Patients who were offered but declined surgery were invited to focus groups. Two independent sample t-tests, Mann-Whitney U tests, and chi-square tests were used for continuous, scored, and categorical variables, respectively, with two-tailed significance <0.05. Qualitative, code-based analysis was performed for the focus groups. RESULTS: The cohort included 321 patients (81 shoulder, 59 hip, and 181 knee) including 199 females (62.0%). There were no differences in proportions of females versus males who underwent JRS or in nonsurgical treatments. Female shoulder arthritis patients were older, had a higher visual analogue pain score, and had a higher Charlson Comorbidity Index. In focus groups, males prioritized waiting for technology advancements to return to an active lifestyle, whereas females experienced negative provider interactions, self-advocated for treatment, concerned about pain, and believed that their sex affected their treatment. DISCUSSION: We found equal utilization of JRS at our institution. However, female patients experienced unique barriers to surgery.

Purpose: To evaluate the gender composition of fellows, faculty, and leaders within orthopaedic sports medicine fellowship programs to provide a more complete description of gender diversity within this subspecialty. Methods: Official program websites of orthopaedic sports medicine fellowships listed on the Arthroscopy Association of North America fellowship directory were examined. Data collected for analysis included the gender of program directors, fellowship faculty, orthopaedic surgery department faculty, current sports medicine fellows, and fellows who graduated within the last 5 years. Results: Of the 132 orthopaedic sports medicine fellows in training in the United States in the 2021 to 2022 academic year, 113 (85.6%) were men and 19 (14.4%) were women (P < .001). Within the past 5 years, 419 fellows were listed as completing a sports medicine fellowship, with 375 (89.5%) being men, and 44 (10.5%) being women (P < .001). There was no significant difference in the gender composition of current fellows compared with the composition of fellows within the last 5 years (P = .74). When we examined gender trends in sports medicine faculty, 639 (86.6%) were men and 99 (13.4%) were women (P < .001). There were 14 women (14.4%) orthopaedic sports medicine faculty in leadership positions (i.e., program director or assistant program director) compared with 83 men in such positions (85.6%) (P < .001). Conclusions: Orthopaedic sports medicine fellowships remain heavily male-dominated on all levels, including fellows, faculty, and leadership. There were no differences in the gender composition of current fellows when compared with those who graduated in the last 5 years, suggesting persistent gender disparity and the need for novel initiatives to enhance gender diversity in sports medicine. Level of Evidence: IV, descriptive study.
RESUMO
INTRODUCTION: Disparities exist and affect outcomes after anterior cruciate ligament (ACL) injury. The purpose of this study was to investigate the association between race, ethnicity, and insurance type on the incidence of ACL reconstruction in the United States. METHODS: The Healthcare Cost and Utilization Project database was used to determine demographics and insurance types for those undergoing elective ACL reconstruction from 2016 to 2017. The US Census Bureau was used to obtain demographic and insurance data for the general population. RESULTS: Non-White patients undergoing ACL reconstruction with commercial insurance were more likely to be younger, male, less burdened with comorbidities including diabetes, and less likely to smoke. When we compared Medicaid patients who had undergone ACL reconstruction with all Medicaid recipients, there was an under-representation of Black patients and a similar percentage of White patients undergoing ACL reconstruction (P < 0.001). DISCUSSION: This study suggests ongoing healthcare disparities with lower rates of ACL reconstruction for non-White patients and those with public insurance. Equal proportions of patients identifying as Black undergoing ACL reconstruction as compared with the underlying general population suggests a possible narrowing in disparities. More data are needed at numerous points of care between injury, surgery, and recovery to identify and address disparities.

Background: Core decompression may be performed for early osteonecrosis with a goal of improving symptoms and potentially delaying the need for total hip arthroplasty. The effectiveness and complication rate of this procedure is not well understood given the relatively rare nature of hip osteonecrosis. Purpose: The purpose of this study is to determine time to total hip arthroplasty (THA) after core compression, assess predictors of early conversion to THA, and to examine complications after hip core decompressions. Methods: Using Current Procedural Terminology (CPT) codes, we queried the Mariner PearlDiver dataset for patients who underwent hip core decompression. Patient demographics were recorded and subsequent THA conversion within 2 years after surgery were tracked. Patient demographic factors, including age, sex, obesity, diabetes, prior fractures, steroid use, tobacco use, or alcohol use, were evaluated as possible predictors of early conversion to THA. International Classification of Diseases (ICD) codes were used to identify complications at 90 days after core decompression. Multiple linear regression was used to test if the patient demographics significantly predicted conversion to THA and complications after core decompression. Results: Between 2010 and 2020, 555 patients underwent hip core decompression. Within 2 years of core decompression, 226 patients converted to THA (40.7%). Age was the only significant risk factor for conversion to THA. The highest proportion of patients (61.1%, 138/226) who converted to THA were between age 40-59. The 90-day complication rate was 2.9% (16/555). The most common complication was femoral neck fracture (11/16 of all complications). Discussion: There is a high failure rate following core decompression for hip osteonecrosis with over one third of patients converting to THA within 2 years. Age was the only variable predictive of conversion to THA. The overall complication rate after core decompression is low at 90 days. Conclusion: Patients should be counseled regarding the risk of early conversion to THA if over 40 and the potential risk of femoral neck fracture.

RESUMO
Female physicians have been historically underrepresented in orthopaedic surgery residencies. The purpose of this study was to determine whether sex diversity among orthopaedic residency programs and faculty is associated with an increased number of female residents matriculating into that program. In addition, we sought to analyze female resident matriculation trends in the past 5 years. Methods: The American Medical Association Fellowship and Residency Electronic Interactive Database was used to identify all allopathic orthopaedic surgery residency programs during the 2021 to 2022 academic year. The number of female residents and interns; the number of female faculty, professors, and associate professors; and the number of women in leadership positions were compared with data from the academic year 2016 to 2017. Continuous data were analyzed with independent t-tests, and significance was set at p < 0.05. Results: A total of 696 female residents (19.2%) were identified from 3,624 orthopaedic residents, an increase from 13.5% in 2016. Programs in the top quartile of female residents had 3 times the number of female residents per program when compared to other quartiles and almost double the number of female interns per program. Programs in the top quartile of female residents had a significantly greater number of female faculty per program than the lower quartiles; 5.76 vs. 4.18. Compared with 2016 to 2017, there were significant increases in female faculty per program from 2.77 to 4.54 along with female full professors from 0.274 to 0.694. These increases contribute to the overall growth in the number of women in leadership positions per program over the past 5 years to 1.01 from 0.35 (p < 0.001). Conclusion: In the past 5 years, the percentage of female residents has increased from 13.5% to 19.2%. Furthermore, women make up 22.1% of interns. Orthopaedic surgery residency programs with higher percentages of female faculty had higher numbers of female residents. By encouraging programs to promote female representation within leadership and residents, we may continue to see the gap in orthopaedic sex diversity close. Level of Evidence: III.
RESUMO
A select subset of patients can present with anterior knee pain in the setting of normal patellar tracking, no significant cartilage damage, and the presence of a bone marrow lesion (BML) involving the patella on advanced imaging. One novel treatment option for this condition is patellar subchondroplasty, where calcium phosphate is injected into the subchondral bone under fluoroscopic guidance. The purpose of this study is to report preliminary outcomes of patients who have undergone subchondroplasty of the patella. The surgical log of the senior author was retrospectively reviewed to identify patients who had undergone patellar subchondroplasty from January 2014 to June 2019. Indications for surgery included the presence of retropatellar pain refractory to conservative management without significant arthritis with a related focal BML on magnetic resonance imaging. International Knee Documentation Committee, Knee Injury and Osteoarthritis Outcome Score (KOOS), and Veterans Rand 12-item Health Survey (VR-12) were obtained preoperatively, at 6 months and at final follow-up. Eight patients (nine knees) who underwent patellar subchondroplasty with minimum 1-year follow-up participated in the study. On preoperative magnetic resonance imaging, patients had a mean BML that was 2 cm in diameter. Patients had a median Kellgren-Lawrence grade of 2 both preoperatively and at final radiographic follow-up (15.50 ± 20.52 months). No patient underwent subsequent surgery or conversion to arthroplasty. Compared with baseline, VR-12 mental (p = 0.046) and physical (p = 0.003), KOOS joint replacement (p = 0.024), KOOS pain (p = 0.033), and KOOS sports (p = 0.034) scores were significantly increased at final follow-up (24.00 ± 13.55 months). In addition, on a scale of 0 to 100, patient-reported satisfaction was 73.88 ± 33.90. This study introduces patellar subchondroplasty as a surgical treatment for patients with symptomatic BMLs of the patella without significant arthritis after failure of conservative management. Our results demonstrated good outcomes and patient satisfaction. In addition, no patients converted to patellofemoral or total knee arthroplasty. This study suggests that patellar subchondroplasty may be a reasonable treatment option in the correct patient population.

PURPOSE: There is little information on patients most at risk for poor outcomes following surgical repair of extensor mechanism tendon injuries. The purpose of this study is to provide an epidemiological overview of patients undergoing patellar or quadriceps tendon repair and to assess the incidence of postoperative complications, readmissions, and revision repairs among this population. METHODS: Retrospective data were obtained using the PearlDiver database for patellar tendon repair and quadriceps tendon repair patients between 2010 and 2020. Baseline demographics, incidences of 90-day readmissions and postoperative complications, and reoperation rates were collected for each group. Multivariate logistic regression was performed to assess the predictive power of each demographic variable on the incidence of postoperative complications and reoperations. RESULTS: In total, 1543 patients underwent patellar tendon repair and 601 underwent quadriceps tendon repair. Complications within 90-days were observed in 33.7% of patients with patellar tendon repair and 39.2% of patients with quadriceps tendon repair. Reoperation rates were 4.2% and 4.8% for patellar tendon repair and quadriceps tendon repair, respectively. Females in both patellar tendon repair and quadriceps tendon repair groups were at significantly higher risk for post-operative complications (patellar tendon repair OR 3.0, 95% CI 2.4-3.7; quadriceps tendon repair OR 2.9, 95% CI 1.9-4.6; p < 0.001 for both). Older age (p < 0.001), female gender (p < 0.001), CCI (p < 0.001), tobacco use (p < 0.001), and obesity (p < 0.01) were all predictors of experiencing at least one complication following patellar tendon repair. For quadriceps tendon repair, female gender (p < 0.001) and CCI (p < 0.001) were the strongest predictors of experiencing at least one complication, while older age, tobacco use, and obesity (p < 0.05 for all) were also significant independent predictors. CONCLUSION: Patellar tendon repair patients are younger on average than quadriceps tendon repair patients. Although females are less likely to sustain extensor mechanism ruptures compared to males, females are significantly more likely to have at least one complication after quadriceps or patellar tendon repair. These findings may be used by surgeons, patients, and payors to understand who is most at risk for adverse outcomes following extensor mechanism repair surgery, resulting in earlier intervention and counseling to reduce the likelihood of a poor outcome following extensor mechanism repair surgery. LEVEL OF EVIDENCE: Level III.

Purpose: To define the minimal clinically important difference (MCID), substantial clinical benefit (SCB) and patient-acceptable symptomatic state (PASS) for patient-reported outcome measures (PROMs) after medial patellofemoral ligament reconstruction (MPFLR) and to investigate the role of preoperative, demographic, and intraoperative variables for predicting achievement of these thresholds. Methods: This retrospective cohort study used a prospectively maintained database of patients undergoing primary MPFLR between August 2015 and December 2019. PROMs included the International Knee Documentation Committee (IKDC), Knee Injury and Osteoarthritis Outcome Score (KOOS), KOOS joint replacement (JR), and Kujala. Anchor-based and distribution-based methods were used to calculate the MCID, SCB, and PASS. Regression analyses were performed to identify prognosticators for achievement of clinically significant thresholds. Results: 139 patients met inclusion criteria (mean age: 21.7± 8.2 years). At 6 months, the MCID values were 8.3 (KOOS-Pain) and 8.5/13.5 (Kujala); SCB values were 1.4 (KOOS-Pain) and 43.7 (KOOS-QOL); and PASS values were 64.9 (IKDC), 83.3 (KOOS-Symptom), 76.8 (KOOS-Pain), 91.2 (KOOS-ADL), 47.5 (KOOS-Sport), 40.6 (KOOS-QOL), and 78.1 (KOOS-JR). At 1 year, the MCID values were 4.2 (KOOS-Pain), 7.2 (KOOS-ADL), 12.4 (KOOS-QOL) and 25.2 (KOOS-JR); SCB were 23.6 (IKDC), 4.2 (KOOS-Symptom), 19.7 (KOOS-Pain), 6.5 (KOOS-ADL), 55.0 (KOOS-Sport), 6.3 (KOOS-QOL), and 19.6/25.2 (KOOS-JR); and PASS were 65.5 (IKDC), 80.4 (KOOS-Symptom), 84.7 (KOOS-Pain), 99.3 (KOOS-ADL), 57.5 (KOOS-Sport), 53.1 (KOOS-QOL), and 76.3 (KOOS-JR). In regression analysis, greater age, body mass index, and preoperative PROMs were negative prognosticators for achieving clinically significant thresholds. Conversely, male gender increased the likelihood of achieving PASS for Kujala at 6 months and KOOS-ADL at 1 year. Conclusions: This study established thresholds for the MCID, SCB, and PASS at 6 months and 1 year after MPFLR, providing physicians an evidence-based method to advise patients and assess outcomes with this surgery. Older patients and those with higher preoperative outcome scores are less likely to report improvement and satisfaction with MPFLR, while male patients are more likely to report some satisfaction. Level of Evidence: Level III, retrospective cohort study (diagnosis).
RESUMO
PURPOSE: To determine the correlation between different patient-reported outcome (PRO) measurements used to assess outcomes after arthroscopic treatment of femoroacetabular impingement syndrome (FAIS) in a single cohort of patients. METHODS: Patients undergoing primary hip arthroscopy for FAIS (without dysplasia, arthritis, or joint hypermobility) were retrospectively analyzed from a prospectively collected cohort. PROs collected before surgery and at 2-year follow-up included the Visual Analog Scale (VAS) for pain, modified Harris Hip Score (mHHS), Hip Disability and Osteoarthritis Outcome Scores (HOOS) with subscales for symptoms, pain, activities of daily living (ADL), sport, and quality of life (QoL), and the physical and mental components of the Short Form-12 (SF-12 PCS and SF-12 MCS). RESULTS: Three hundred patients with 2 years' follow-up (mean age 35.1 ± 11.3, BMI 24.7 ± 3.8, 52.7% female, median Tönnis grade 1) were identified. All patients underwent femoroplasty and labral repair. There was a strong correlation among nearly all the PRO surveys at 2-year follow-up, with the highest correlations identified between mHHS and HOOS-Pain (r = .86, P < .001) and mHHS and HOOS-ADL (r = .85, P < .001). Preoperative scores and the change from preoperative to postoperative scores demonstrated an overall moderate correlation between surveys. There was a consistently weak correlation between the SF-12 MCS and all other PROs. There were strong agreements (67%-77%) in the patients achieving minimal clinically important differences (MCID) for each PRO survey. All surveys except the SF-12 demonstrated a ceiling effect after surgery, with 13% to 43% of patients achieving the maximum score. CONCLUSIONS: PRO surveys used for FAIS demonstrate strong correlations, especially in the evaluation of patients during the postoperative period. MCID for VAS, mHHS, and HOOS demonstrate strong agreement, whereas large ceiling effects were seen with the mHHS and HOOS. The results support a more efficient use of PRO scores while being able to accurately capture patient outcomes. LEVEL OF EVIDENCE: IV, retrospective case series.

PURPOSE OF REVIEW: Determining the correct diagnosis can be challenging in patients presenting with hip pain. The physical examination is an essential tool that can aid in diagnosis of hip pathology. The purpose of this review is to provide an updated summary of recent literature on the physical exam of the hip, particularly as it relates to diagnosis of femoroacetabular impingement (FAI) syndrome, labral injury, and hip microinstability. RECENT FINDINGS: Physical exam findings consistent with the diagnosis of FAI include reduced supine hip internal rotation and positive flexion-adduction-internal rotation maneuvers. Labral tears can be detected on exam with the Scour test. Studies demonstrate altered hip biomechanics in patients with FAI during activities such as walking and squatting. Those with FAI have slower squat velocities, slower sit-to-stand tests, and increased hip flexion moments during ambulation. Hip microinstability is a dynamic process, which can occur after prior hip arthroscopy. For hip microinstability, the combination of the three following positive tests (anterior apprehension, abduction-extension-external rotation, and prone external rotation) is associated with a 95% likelihood of microinstability as confirmed by examination under anesthesia at the time of surgery. A comprehensive hip physical exam involves evaluation of the hip in multiple positions and assessing hip range of motion, strength, as well as performing provocative testing. A combination of physical exam maneuvers is necessary to accurately diagnose FAI syndrome and labral pathology as individual tests vary in their sensitivity and specificity. While an elevated level of suspicion is needed to diagnose hip microinstability, the provocative tests for microinstability are highly specific.
RESUMO
PURPOSE OF REVIEW: As the incidence of shoulder arthroplasty continues to increase, there is growing interest in patient-based factors that may predict outcomes. Based on existing literature demonstrating gender-based disparities following total hip and knee arthroplasty, gender may also influence shoulder arthroplasty. The purpose of this review is to discuss the recent literature on the influence of gender on shoulder arthroplasty, focusing on differences in preoperative parameters, perioperative complications, and postoperative outcomes. RECENT FINDINGS: While both female and male patients generally benefit from shoulder arthroplasty, several differences may exist in preoperative factors, acute perioperative complications, and postoperative outcomes. Preoperatively, female patients undergo shoulder arthroplasty at an older age compared to their male counterparts. They may also have greater levels of preoperative disability and different preoperative expectations. Perioperatively, female patients may be at increased risk of extended length of stay, postoperative thromboembolic events, and blood transfusion. Postoperatively, female patients may achieve lower postoperative functional scores and decreased range of motion compared to male patients. Differences in postoperative functional scores may be influenced by gender-based differences in activities of daily living. Finally, female patients may be at greater risk for periprosthetic fracture and aseptic loosening while male patients appear to be at greater risk for periprosthetic infection and revision surgery. Current literature on the influence of gender on shoulder arthroplasty is limited and conflicting. Further research is necessary to delineate how gender affects patients at the pre- and postoperative levels to better inform decision-making and outcomes.
RESUMO
PURPOSE: The purpose of this study was to compare outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) in patients with borderline hip dysplasia and hip instability defined radiographically using the femoroepiphyseal acetabular roof (FEAR) index and in patients without radiographic evidence of hip instability. METHODS: Data from consecutive patients with borderline hip dysplasia (lateral center edge angle between 18Ë-25Ë) who underwent primary hip arthroscopy between April 2012 and June 2017 for the treatment of FAIS were analyzed. Baseline demographic data, radiographic parameters, preoperative, and 2-year postoperative patient-reported outcome measures were collected. The FEAR index was measured by 3 different observers. Patients with an average FEAR index ≥2Ë were categorized as having radiographic evidence of instability as previously published. The analysis was powered to detect a minimal clinically important difference (MCID) for each outcome score. Statistical analysis was performed as appropriate to compare patients with FEAR index ≥2 and <2°. RESULTS: A total of 140 patients met the inclusion criteria. The average age and body mass index of included patients was 31.7 ± 13.2 (P < .325) years and 25.1 ± 5.6 kg/m2 (P < .862). There were no statistically significant demographic differences between the groups. Nineteen (13.0%) patients were found to have a FEAR index of over 2Ë. The FEAR index <2° and FEAR index ≥2° groups had a mean preoperative FEAR index (standard deviation, range) of -7.0 (5.2, -26.8 to 1.9) and 4.8 (2.5, 2.0-11.8), respectively. The interrater intraclass correlation coefficient was 0.96. Postoperative patient-reported outcomes and rates of MCID and patient-acceptable symptomatic state achievement were not statistically different between the radiographically stable and unstable groups. (p>0.05 for all). CONCLUSION: Patients with borderline hip dysplasia and radiographic evidence of hip instability, as measured by the FEAR index (≥2°), achieve similar improvement in 2-year outcomes compared to those with radiographically stable hips after arthroscopic treatment of FAIS. CLINICAL RELEVANCE: Retrospective Level III cohort study.
