No Differences Between White and Non-White Patients in Terms of Care Quality Metrics, Complications, and Death After Hip Fracture Surgery When Standardized Care Pathways Are Used.

BACKGROUND: Many initiatives by medical and public health communities at the national, state, and institutional level have been centered around understanding and analyzing critical determinants of population health with the goal of equitable and nondisparate care. In orthopaedic traumatology, several studies have demonstrated that race and socioeconomic status are associated with differences in care delivery and outcomes of patients with hip fractures. However, studies assessing the effectiveness of methods to address disparities in care delivery, quality metrics, and complications after hip fracture surgery are lacking. QUESTIONS/PURPOSES: (1) Are hospital quality measures (such as delay to surgery, major inpatient complications, intensive care unit admission, and discharge disposition) and outcomes (such as mortality during inpatient stay, within 30 days or within 1 year) similar between White and non-White patients at a single institution in the setting of a standardized hip fracture pathway? (2) What factors correlate with aforementioned hospital quality measures and outcomes under the standardized care pathway? METHODS: In this retrospective, comparative study, we evaluated the records of 1824 patients 55 years of age or older with hip fractures from a low-energy mechanism who were treated at one of four hospitals in our urban academic healthcare system, which includes an orthopaedic tertiary care hospital, from the initiation of a standardized care pathway in October 2014 to March 2020. The standardized 4-day hip fracture pathway is comprised of medicine comanagement of all patients and delineated tasks for doctors, nursing, social work, care managers, and physical and occupational therapy from admission to expected discharge on postoperative day 4. Of the 1824 patients, 98% (1787 of 1824) of patients who had their race recorded in the electronic medical record chart (either by communicating it to a medical provider or by selecting their race from options including White, Black, Hispanic, and Asian in a patient portal of the electronic medical record) were potentially eligible. A total of 14% (249 of 1787) of patients were excluded because they did not have an in-state address. Of the included patients, 5% (70 of 1538) were lost to follow-up at 30 days and 22% (336 of 1538) were lost to follow-up at 1 year. Two groups were established by including all patients selecting White as primary race into the White cohort and all other patients in the non-White cohort. There were 1111 White patients who were 72% (801) female with mean age 82 ± 10 years and 427 non-White patients who were 64% (271) female with mean age 80 ± 11 years. Univariate chi-square and Mann-Whitney U tests of demographics were used to compare White and non-White patients and find factors to control for potentially relevant confounding variables. Multivariable regression analyses were used to control for important baseline between-group differences to (1) determine the correlation of White and non-White race on mortality, inpatient complications, intensive care unit (ICU) admissions, and discharge disposition and (2) assess the correlation of gender, socioeconomic status, insurance payor, and the Score for Trauma Triage in the Geriatric and Middle Aged (STTGMA) trauma risk score with these quality measures and outcomes. RESULTS: After controlling for gender, insurer, socioeconomic status and STTGMA trauma risk score, we found that non-White patients had similar or improved care in terms of mortality and rates of delayed surgery, ICU admission, major complications, and discharge location in the setting of the standardized care pathway. Non-White race was not associated with inpatient (odds ratio 1.1 [95% CI 0.40 to 2.73]; p > 0.99), 30-day (OR 1.0 [95% CI 0.48 to 1.83]; p > 0.99) or 1-year mortality (OR 0.9 [95% CI 0.57 to 1.33]; p > 0.99). Non-White race was not associated with delay to surgery beyond 2 days (OR = 1.1 [95% CI 0.79 to 1.38]; p > 0.99). Non-White race was associated with less frequent ICU admissions (OR 0.6 [95% CI 0.42 to 0.85]; p = 0.03) and fewer major complications (OR 0.5 [95% CI 0.35 to 0.83]; p = 0.047). Non-White race was not associated with discharge to skilled nursing facility (OR 1.0 [95% CI 0.78 to 1.30]; p > 0.99), acute rehabilitation facility (OR 1.0 [95% CI 0.66 to 1.41]; p > 0.99), or home (OR 0.9 [95% CI 0.68 to 1.29]; p > 0.99). Controlled factors other than White versus non-White race were associated with mortality, discharge location, ICU admission, and major complication rate. Notably, the STTGMA trauma risk score was correlated with all endpoints. CONCLUSION: In the context of a hip fracture care pathway that reduces variability from time of presentation through discharge, no differences in mortality, time to surgery, complications, and discharge disposition rates were observed beween White and non-White patients after controlling for baseline differences including trauma risk score. The pathway detailed in this study is one iteration that the authors encourage surgeons to customize and trial at their institutions, with the goal of providing equitable care to patients with hip fractures and reducing healthcare disparities. Future investigations should aim to elucidate the impact of standardized trauma care pathways through the use of the STTGMA trauma risk score as a controlled confounder or randomized trials in comparing standardized to individualized, surgeon-specific care.

Surface Mapping of the Musculotendinous Attachments at the Pubic Symphysis in Cadaveric Specimens: Implications for the Treatment of Core Muscle Injury.

PURPOSE: To characterize the 3-dimensional muscular, musculotendinous, and neurovascular anatomy about the pubic symphysis relevant to core muscle injury (CMI). METHODS: Ten cadaveric hips were dissected to characterize the musculotendinous insertion of the rectus abdominis and inguinal ligament, origins of the adductor longus and adductor brevis, and the pubic cartilage plate. A 3-dimensional coordinate measuring system and data acquisition software were used to calculate structure cross-sectional area, and the landmark anatomical relationships to 1 another and relevant neurovascular structures. RESULTS: All specimens were male with an average age of 62 ± 2 years. The mean footprints of the rectus abdominis, inguinal ligament, adductor longus, and adductor brevis were 8.4 ± 3.1, 1.2 ± 0.5, 3.8 ± 1.6, and 2.9 ± 1.3 cm2, respectively. The mean pectineus and gracilis footprints were 6.3 ± 2.4 and 3.4 ± 0.9 cm2, respectively. The mean cross-sectional area of the cartilage plate was 24.8 ± 5.6 cm2. The adductor longus was an average 1.5 ± 0.25 cm from the adductor brevis and 0.69 ± 0.52 cm from the rectus abdominis. The genital branch of the genitofemoral nerve was an average of 4.3 cm (range, 2.8-6.4) lateral to the insertion of the inguinal ligament. The femoral vein and artery were 3.0 cm (range, 2.5-3.6) and 3.7 cm (range, 2.5-5.9) lateral to the inguinal ligament footprint. The obturator nerve was 2.5 cm (range, 1.6-3.4) lateral to the adductor longus. CONCLUSIONS: Familiarity with the anatomy of the pubic symphysis is essential for surgeons treating patients with CMI. We have shown that this relatively small area is the site of many muscular, musculotendinous, and neurovascular structures with various sized footprints and described the 3-dimensional anatomy of the anterior pubic symphysis. The origin of the adductor longus lies in close proximity to other structures, such as the adductor brevis, the insertion of the rectus abdominis, and the obturator nerve. These findings should be considered when operating in this region and treating patients with chronic groin pain. CLINICAL RELEVANCE: The anatomy of the pelvic region and pubic symphysis has not been well characterized. Intimate knowledge of relevant anatomy is essential to treating CMI, also known as athletic pubalgia or sports hernia.

Preoperative Predictors of Achieving Clinically Significant Athletic Functional Status After Hip Arthroscopy for Femoroacetabular Impingement at Minimum 2-Year Follow-Up.

PURPOSE: To identify predictors of achieving clinically significant sport function in athletic patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). METHODS: Data were analyzed for all patients who treated for FAIS between 2012 to 2016 and reported being athletes, including recreational and competitive athletes. All patients had a minimum of 2-year follow-up with patient-reported athletic function in the form of the Hip Outcome Score-Sport Specific (HOS-SS), visual analog score-pain, and patient satisfaction. Achieving clinically significant sports function was defined as either reaching the minimally clinical important difference (MCID) or the patient acceptable symptomatic state (PASS) for HOS-SS at 2-year follow-up. An exploratory factor analysis was used to determine specific domains for the predictor variables and to reduce the redundancy in these variables. A logistic regression analysis was used to identify significant predictors of achieving clinically significant sports function [corrected]. RESULTS: Of 780 qualifying patients, 626 completed the 2-year minimum follow-up (80%), with a mean age and body mass index of 31.6 ± 11.9 years and 24.6 ± 8.6, respectively. A total of 500 patients (86.5%) achieved high functional status, with 77.9% achieving MCID HOS-SS and 68.7% achieving PASS HOS-SS. Logistic regression analysis identified increased the α angle (odds ratio [OR] 0.976; P = .027), preoperative pain duration (OR 0.729; P = .011), and body mass index (BMI) (OR 0.919; P = .018), as well as the presence of femoral chondral defects (OR 0.769; P = .013), as negative predictors for achieving MCID. Negative predictors for achieving PASS HOS-SS included the presence of a preoperative limp (OR 0.384; P = .013), anxiety or depression (OR 0.561; P = .041), and increased BMI (OR 0.945; P = .018) and preoperative pain duration (OR 0.987; P < .001). CONCLUSIONS: Several predictors of achieving clinically significant sport function performance exist, including a history of anxiety or depression, BMI, preoperative α angle, limp, femoral chondral damage, *and preoperative symptom duration. Our results suggest there are both modifiable and nonmodifiable preoperative factors that have the potential to predict achieving high athletic function after hip arthroscopy for FAIS.

Assessment of Association Between Spino-Pelvic Parameters and Outcomes Following Gluteus Medius Repair.

PURPOSE: To evaluate postoperative coronal/sagittal spinal plane and spinopelvic parameters in patients undergoing gluteus medius repair and to identify associations between outcomes and the aforementioned spinopelvic variables. METHODS: Patients who underwent gluteus medius/minimus repair by a single surgeon between January 20, 2012, and November 25, 2015, were retrospectively identified from a prospectively collected database. Radiographic measurements included Cobb angle, lumbar lordosis, sagittal vertical axis (SVA), pelvic tilt, sacral slope, and pelvic incidence. Patient-reported outcomes (PROs) were obtained at baseline and a minimum of 22 months after surgery. Bivariate correlation determined effects of spinopelvic measurements on PROs. Scoliosis and nonscoliosis groups were compared using independent samples t-test, and multivariate analysis determined whether the preoperative variables affected outcomes. RESULTS: Thirty-eight (80.9%) of 47 consecutive patients were radiographically evaluated with a scoliosis series. All patients demonstrated significant improvements in all PROs and pain (P < .001 for all), as well as at an average 28.2 ± 7.8 (range, 22-51) months after surgery. There were significant negative relationships between SVA and Hip Outcome Score-Activities of Daily Living (r = -0.405, P = .026) and Hip Outcome Score-Sports Specific (r = -0.492, P = .011) scores. Patients with a positive SVA (>0 cm) had significantly worse patient-reported outcomes than their counterparts with negative (≤0 cm) SVA. Also, patients with positive sagittal plane deformity (SVA >5 cm) had significantly worse HOS-SS than patients without positive sagittal plane deformity (SVA <5 cm) (47.0 ± 35.3, 73.2 ± 24.0; P = .04). Independent sample t-testing for the patients with scoliosis (n = 18) versus no scoliosis (n = 20) demonstrates a significantly worse postoperative International Hip Outcome Tool (short version) score in the patients with scoliosis (77.4 ± 15.1, 53.8 ± 37.1; P = .043). CONCLUSIONS: Patients with scoliosis presented with lower rates of symptom improvement and ability to return to an active lifestyle in patients with hip disorders. In addition, patients with positive sagittal plane deformity experienced lower hip-related sport-specific outcome scores. Although the direct relationship between the spine and the hip in patients after gluteus medius/minimus repair remains unclear, this study shows an association between these postoperative outcomes and spinopelvic parameters. LEVEL OF EVIDENCE: Level IV, case series.

Patients With Unilateral Femoroacetabular Impingement Syndrome Have Asymmetrical Hip Muscle Cross-Sectional Area and Compensatory Muscle Changes Associated With Preoperative Pain Level.

PURPOSE: To compare the symptomatic hip muscle cross-sectional area (CSA) in patients with unilateral femoroacetabular impingement syndrome (FAIS) with the asymptomatic-side hip muscle CSA and to determine whether correlations exist between the hip muscle CSA and preoperative pain level, preoperative symptom duration, and postoperative function. METHODS: We performed a retrospective review of magnetic resonance imaging data of patients who underwent hip arthroscopy from January 2012 through June 2015 for the treatment of unilateral FAIS and who had a minimum of 2 years' follow-up after hip arthroscopy for FAIS. A picture archiving and communication system workstation with an embedded region-of-interest tool was used to measure the muscle CSA of both the symptomatic and asymptomatic sides in FAIS patients. One-way repeated-measures analyses of variance were used to determine differences between symptomatic and asymptomatic hip muscle CSAs. Spearman rank correlations were used to determine relations between the symptomatic-side hip muscle CSA and preoperative pain level, preoperative symptom duration, and multiple validated patient-reported outcomes to quantify the level of function. RESULTS: A total of 50 patients met the inclusion criteria and were analyzed. The mean age of the patients was 34.22 ± 14.12 years, and 64% were women. Specific muscles of the symptomatic hip displaying significantly decreased CSAs compared with the asymptomatic hip included the gluteus maximus (P = .007), gluteus minimus (P = .022), and rectus femoris (P = .028). The tensor fascia lata (ρ = 0.358; P = .011), pectineus (ρ = 0.369, P = .008), adductor longus (ρ = 0.286, P = .044), and obturator externus (ρ = 0.339, P = .016) showed a moderate positive correlation with preoperative pain level on a visual analog scale in unilateral FAIS patients. No associations were found between the symptomatic-side hip muscle CSA in patients with unilateral FAIS and symptom duration or patient-reported function. CONCLUSIONS: Patients with unilateral FAIS have a significantly decreased muscle CSA in the symptomatic hip compared with the asymptomatic hip. The symptomatic-side hip muscle CSA was correlated with the preoperative pain level on a visual analog scale. The association between the muscle CSA and preoperative pain level may represent a compensatory change in muscle function around the hip joint in patients with unilateral FAIS. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Intra-articular Volume Reduction With Arthroscopic Plication for Capsular Laxity of the Hip: A Cadaveric Comparison of Two Surgical Techniques.

PURPOSE: To compare intracapsular volume reduction between interportal capsular shift and T-capsulotomy plication in a cadaveric model. METHODS: Twelve pair-matched specimens were randomized into T-capsulotomy plication or interportal capsular shift. T-capsulotomy was performed using a 2-cm interportal and 2-cm bisecting, longitudinal limb to the intertrochanteric line. Plication was performed utilizing 5-mm bites on either side of the capsulotomy with arthroscopic knot tying technique standard alternating half hitches. Pair-matched interportal capsular shift specimens underwent 5-cm interportal capsulotomy, and capsular shift was performed utilizing 5 nonabsorbable sutures placed in 45° orientation at 5 mm from the capsulotomy margin. With each specimen in a position of slight flexion and adduction, a spinal needle was used to inject methylene blue-colored saline solution intra-articularly; the volcano method was used to measure capsular volume before and after each respective plication technique. Mean absolute volumes and relative volumetric reduction for each technique were quantified and compared to determine statistical significance. RESULTS: At baseline, there were no statistically significant differences in capsular volume between pair-matched specimens (T-capsulotomy plication, 42.5 ± 5.1 mL; interportal capsular shift, 45.0 ± 88.6 mL; P = .555). After capsulotomy and secondary plication, both the T-capsulotomy (post: mean = 32.5 ± 8.0 mL; P < .001) and interportal capsulotomy groups (post: mean = 29.4 ± 10.0; P < .0001) demonstrated significant decreases in capsular volume, with average reductions of 10.0 ± 3.3 mL and 15.6 ± 3.2 mL, respectively. Although the interportal capsular shift (35.9% ± 11.3%) demonstrated greater volumetric reduction relative to baseline when compared with the T-capsular plication (24.5% ± 10.8%), these results were not significant (P = .104). CONCLUSIONS: Both T-capsular plication and interportal capsular shift produce statistically significant reductions in overall hip capsular volume. Although the interportal capsular shift may generate modestly higher degrees of capsular reduction, the comparative biomechanical repercussions of each technique are not currently known. CLINICAL RELEVANCE: Irrespective of arthroscopic technique, capsular plication with 5-mm bites decreases capsular volume by approximately one-third to one-fourth that of baseline measures.

Editorial Commentary: Smarter Than a Sixth Grader? Hip Arthroscopists, Check Your Training at the Door.

Literacy is one of the best predictors of an individual's health, and providing effective, patient-centered communication to our less literate patients has become a challenge for the entire medical community. The internet has become patients' first-line source of medical information, and as caretakers of musculoskeletal medicine, it is orthopaedists' responsibility to provide high-quality, patient-centric resources that are simple and clear. When creating our own practice or institution's websites, we must check our training and technicality at the door to create resources that are easily readable and digestible.

Editorial Commentary: What Irks a Hip Arthroscopist? Intraoperative Anchor Failure.

Intraoperative suture anchor failure is a seemingly unavoidable event during hip arthroscopy and it can happen to the best of us. To date, biomechanical cadaveric studies saturate hip anchor failure literature with only one known, published in vivo investigation. We now know that intraoperative anchor failure is an uncommon occurrence that does not significantly vary between basic population demographics. However, we have only been provided with foundational knowledge, and our community must continue to expand upon the basics.

Editorial Commentary: Is Vitamin D the New Wheaties? Preventing Muscle Fatigue Could Keep Athletes in the Game.

Vitamin D deficiency is an oft overlooked and underevaluated condition that is widespread in patient-athletes, including the elite and professional. Although the symptomatology of this deficiency is well known in the general population (osteoporosis and increased risk of fracture), the symptom of muscle fatigue is not. It is only recently that the association between vitamin D deficiency and muscle fatigue in professional athletes has been placed in the spotlight. However, vitamin D deficiency should be of increasing concern for orthopaedists in regard to all athletes. In the elite collegiate/professional ranks, this condition may lead to detrimental injuries with career-altering effects. Although this condition may not affect career and financial well-being for most patients, modifications in athletic performance and lifestyle are still of utmost value to any athlete. Although I do not condone ordering vitamin D levels as a screening tool, nor broadly prescribing supplements to all patient-athletes, I do believe that it is warranted if certain "high-risk" criteria are met.

Return to Golf After Arthroscopic Management of Femoroacetabular Impingement Syndrome.

PURPOSE: To investigate if patients who reported playing golf before arthroscopic hip surgery for femoroacetabular impingement syndrome were able to return to playing golf postoperatively. METHODS: The study was a retrospective analysis of all consecutive patients undergoing hip arthroscopy for femoroacetabular impingement syndrome between 2012 and 2014. Inclusion criteria required that a patient (1) reported playing golf before the surgery, (2) had a minimum 2-year follow-up, and (3) completed patient-reported outcome measures. An electronic postoperative return to golf questionnaire was completed by patients who reported golf as an activity. To evaluate patients' ability to return to golf after surgery, the following variables were analyzed with paired samples t test and χ-square tests: handedness, holes played, modified-Harris Hip Score, and Hip Outcome Score Activity of Daily Living and Sports-Specific Subscale. RESULTS: A total of 29 patients (22 men; age, 36.0 ± 11.9 years) with a minimum of 24 months of follow-up who self-reported playing golf preoperatively were included in the analysis. Preoperatively, 23 patients (79%) had discontinued golfing owing to activity-related hip complaints. At the final follow-up, all patients had significant improvements in the Hip Outcome Score Activity of Daily Living (preoperatively, 65.9 ± 19.9; postoperatively, 91.5 ± 12.8; P < .0001), the Hip Outcome Score Sports-Specific Subscale (38.2 ± 23.5, 79.7 ± 28.8; P = .0002), and modified-Harris Hip Score (54.8 ± 15.6; 84.2 ± 15.8; P < .0001). Additionally, there was a decrease in pain from 7.34 ± 1.63 to 1.71 ± 2.3 postoperatively (P < .0001), and 97% of patients returned to golf at an average of 7.2 months postoperatively. Postoperatively, 55% of patients (n = 16) noted improved golfing performance, 41% (n = 11) returned to their preinjury level, 1 patient (3%) returned at a lower level owing to non-hip-related problems, and 1 (3%) did not return to golf owing to fear of reinjury. CONCLUSIONS: Arthroscopic treatment of femoroacetabular impingement syndrome in patients who reported playing golf before surgery resulted in significant improvements in hip function and predictably high rates of patient satisfaction, with 97% returning to golfing activity and 55% noting improvement from preinjury sporting performance. LEVEL OF EVIDENCE: Level IV, retrospective case series.

The Influence of Pain in Other Major Joints and the Spine on 2-Year Outcomes After Hip Arthroscopy.

PURPOSE: To determine whether patients who have pain in other major joints or the spine have poorer postsurgical outcomes than patients without comorbid orthopaedic pain. METHODS: We performed a review of a prospectively maintained institutional surgical registry of patients who underwent hip arthroscopy between January 1, 2012, and July 16, 2015, by a single surgeon, with a minimum of 2 years of postoperative follow-up. A musculoskeletal morbidity (MSM) score was assigned to each patient preoperatively based on the presence of pain in other joints and the spine (grade 1, hip only; grade 2, hip and other major joints without spine; grade 3, hip with spine; and grade 4, hip and other major joints with spine). Preoperatively and at 2 years postoperatively, functional outcomes were measured using the Hip Outcome Score-Activities of Daily Living (HOS-ADL), and the percentages of patients achieving a minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) were calculated. RESULTS: In total, 821 patients were identified, of whom 700 (85.3%) completed 2-year follow-up. Preoperatively, MSM grade 1 patients had a higher HOS-ADL than grade 2 patients (P = .02), but there was no difference between grade 1 and grade 3 patients (P = .63) or between grade 1 and grade 4 patients (P = .14). Likewise, there was no difference in the preoperative HOS-ADL among grades 2, 3, and 4. Patients with MSM grades 1 and 2 were younger than those with grades 3 and 4. At 2 years postoperatively, MSM grade 1 patients had higher HOS-ADL values than grade 3 (P = .01) and grade 4 (P = .02) but not grade 2 (P = .07) patients. Overall, 84% of patients showed an MCID and 72% of patients achieved a PASS with regard to the HOS-ADL. There were no statistically significant differences among MSM grades in terms of the MCID or PASS. CONCLUSIONS: Overall, 84% of patients improved with hip arthroscopy by MCID criteria for the HOS-ADL. Patients with no pain in other joints (MSM grade 1) had better 2-year postoperative HOS-ADL values after hip arthroscopy than patients with spine pain (grades 3 and 4). However, there were no significant differences in the MCID or PASS among patients with regard to MSM grade. A total of 40.5% of patients who underwent hip arthroscopy had pain in another joint. A limitation, however, is that there is potential for a type II error, in that there may not have been a sufficient number of patients studied to detect a significant difference in outcome among patients with different grades of musculoskeletal comorbidity. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

In-Office Needle Arthroscopy for Superior Labral Tear Debridement.

SLAP tears are a common cause of shoulder pain in overhead athletes. The benefits of in-office nano-arthroscopy include the ability to diagnosis and treat biceps tendinopathy, quicker patient recovery, reduced health care costs, and improved patient satisfaction.

The purpose of this technical note is to describe the technique for performing in-office needle arthroscopy for chondral or osteochondral contained lesions of the knee, with special consideration of the technique for obtaining adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.

How Should We Define Clinically Significant Outcome Improvement on the iHOT-12?

BACKGROUND: There is increased emphasis on efficiently administering patient-reported outcome measures (PROMs). The International Hip Outcome Tool-12 (iHOT-12) is a short-form version of the iHOT-33, and relatively little is known about clinically significant outcomes using the iHOT-12. QUESTIONS/PURPOSES: The purpose of this study was to define minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) for the iHOT-12 and to identify predictors for achieving these psychometric end points in patients undergoing arthroscopic treatment of femoroacetabular impingement (FAI). METHODS: Data was prospectively collected and retrospectively analyzed as part of an institutional hip preservation repository. One hundred and twenty patients were included; mean age and body mass index (BMI) were 38.7 years and 25.9, respectively. A majority of patients were female (67.5%) and white (81.7%) and participated in recreational sports (79.2%). The iHOT-12 was administered pre-operatively and at 1-year follow-up to patients undergoing primary hip arthroscopy for FAI. The following anchor question was also asked at 1-year follow-up: "Taking into account all the activities you have during your daily life, your level of pain, and also your functional impairment, do you consider that your current state is satisfactory?" MCID was calculated using a distribution-based method. Receiver-operating characteristic analysis with area under the curve was used to confirm the significance of the PASS threshold. RESULTS: Mean iHOT-12 scores improved from 35.6 at pre-operative assessment to 70.7 at 1-year follow-up. Patients indicating satisfaction with their outcome improved from 37.5 pre-operatively to 79.0 at 1-year follow-up. MCID value for the iHOT-12 was 13.0. The PASS threshold was 63.0, indicating an excellent predictive value that patients scoring above this threshold were likely to have met an acceptable symptom state. Worker's compensation patients and those with increased BMI were less likely to achieve PASS; lower pre-operative iHOT-12 score was predictive for achieving MCID, and achieving MCID was predictive for achieving PASS. CONCLUSION: This is the first study to define PASS and MCID for the iHOT-12, which measures clinically significant outcome improvement comparably to that of other commonly used hip PROMs. As its use becomes more widespread, the iHOT-12 data-points presented in this study can be used to determine clinically significant improvement of patient-reported outcomes.

Do Female Athletes Return to Sports After Hip Preservation Surgery for Femoroacetabular Impingement Syndrome?: A Comparative Analysis.

BACKGROUND: Female patients undergoing surgery for femoroacetabular impingement syndrome (FAIS) often experience inferior clinical outcomes and higher failure rates when compared with male patients. The influence of athletic status on hip arthroscopic outcomes in female patients, however, is unclear. PURPOSE: To compare patient-reported outcomes (PROs) of athletic and nonathletic female patients undergoing hip arthroscopic surgery for FAIS, and to determine the return-to-sports rate in the athlete group. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Two-year PROs were assessed in female patients who had undergone hip arthroscopic surgery for FAIS by a single surgeon. Patients who self-identified as athletes were compared with nonathletes. Preoperative and postoperative PRO scores including the Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sport-Specific (HOS-SS), modified Harris Hip Score (mHHS), and visual analog scale (VAS) for pain and satisfaction were analyzed and compared between athletes and nonathletes. Subanalysis was performed based on patient age and body mass index (BMI). RESULTS: A total of 330 female patients undergoing hip arthroscopic surgery for FAIS were identified. Of these, 221 patients identified as athletes (mean age, 29.1 ± 11.1 years; mean BMI, 23.0 ± 3.5 kg/m2) and 109 as nonathletes (mean age, 39.3 ± 11.4 years; mean BMI, 27.8 ± 5.8 kg/m2). Both groups demonstrated improvements in HOS-ADL, HOS-SS, mHHS, VAS for pain, and VAS for satisfaction scores (P < .001 for all). Athletes had significantly higher postoperative PRO scores compared with nonathletes (P < .001 for all). A 1:1 matched-pair subanalysis of 97 athletes and 97 nonathletes controlling for age and BMI indicated that these relationships held independently of potential demographic confounders (P < .001 for all). The number of patients meeting the minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) for the HOS-ADL, HOS-SS, and mHHS was significantly higher in athletes aged ≤25 years versus those aged >25 years and for athletes versus nonathletes (P < .05 for all). Further, 189 of 194 athletes returned to sports at a mean of 6.0 ± 3.9 months postoperatively, with 93.7% reporting returning to the same or higher level of competition. CONCLUSION: Among female patients undergoing hip arthroscopic surgery for FAIS, patients considered athletes achieved superior clinical outcomes compared with patients considered nonathletes. In addition, younger female athletes had higher rates of achieving the MCID and PASS for all PRO measures.
