Knotless Tensionable Anchors: Versatility, Tips, and Tricks.

Arthroscopic surgery, including implants and advanced techniques, continues to advance in the field of orthopaedics. The evolution of suture anchors has undergone design changes, passing from first-generation metal anchors, biodegradable materials, different plastic polymers, to all-suture constructs. Knotless technology also has been found to be a more reproducible method and have comparable outcomes with those found using knotted anchors. This Technical Note describes the advantages and different ways this tensionable anchor can be used in arthroscopic procedures. This implant and its understanding will be useful in the sports medicine area by simplifying procedures and making them more reproducible. The aim of the present Technical Note is to detail the simplicity and versatility of the anchor and discuss different scenarios in which this technology can be used to address common hip pathologies.

No Difference in Patient-Reported Outcomes for Periacetabular Osteotomy and Hip Arthroscopy With Capsular Plication in the Setting of Borderline Hip Dysplasia: A Propensity-Matched Multicenter Study With Minimum 5-Year Follow-Up.

PURPOSE: To compare minimum 5-year patient-reported outcome measures after hip arthroscopy (HA) and periacetabular osteotomy (PAO) for borderline hip dysplasia. METHODS: Hips with a lateral center-edge angle (LCEA) between 18° and less than 25° that underwent either PAO or HA were selected from 2 institutions. The exclusion criteria were as follows: LCEA less than 18°, Tönnis osteoarthritis grade greater than 1, prior hip surgical procedures, active inflammatory disease, Workers' Compensation, and concomitant surgery. Patients underwent propensity matching based on age, sex, body mass index, and Tönnis osteoarthritis grade. Patient-reported outcome measures included the modified Harris Hip Score, as well as calculation of the minimal clinically important difference, patient acceptable symptom state, and maximum outcome improvement satisfaction threshold. Preoperative radiographic predictors included comparison of the Femoro-epiphyseal Acetabular Roof index and ligamentum teres lesions. RESULTS: A total of 28 PAO patients underwent propensity matching to 49 HA patients. The 2 groups were similar in terms of mean age, sex, preoperative body mass index, and LCEA. The PAO group had a longer mean follow-up period (95.8 months vs 81.3 months, P = .001). The mean Femoro-epiphyseal Acetabular Roof index was significantly lower preoperatively in the HA group (P < .001). The 2 groups showed similar and significant improvements in the mean modified Harris Hip Score from preoperatively to latest follow-up (P < .001). The relative risk of subsequent surgery in the PAO group was 3.49 (P = .024), mostly attributed to hardware removal (25%). The revision rate was 3.6% in the PAO group and 8.2% in the HA group (P = .65). One patient in the PAO group required revision HA for intra-articular adhesions. Three of the patients requiring revision in the HA group underwent PAO because of persistent pain, and one underwent revision HA alone. Conversion to total hip arthroplasty was required in 1 patient in the HA group and no patients in the PAO group. CONCLUSIONS: Both PAO and HA with capsular plication provide borderline hip dysplasia patients with clinically significant improvements and low revision rates at a minimum of 5 years postoperatively. LEVEL OF EVIDENCE: Level III, retrospective, comparative therapeutic trial.

Editorial Commentary: Outcome After Ipsilateral Hip Arthroscopy Predicts Outcomes on the Contralateral Side, Regardless of Time Between Surgeries.

Surgical predictability is a multifactorial methodology of coordinated actions backed by clinical expertise and historical tracking. Recent research shows outcome after ipsilateral hip arthroscopy predicts outcomes on the contralateral side, regardless of time between surgeries. This is based on research by experienced surgeons who have achieved reproducibility, predictability, and consistency of their outcomes. To patients at time of scheduling, this translates to, "Trust us, we know what we're doing." This research may not be generalizable to low volume or inexperienced hip arthroscopists.

Arthroscopic Peripheral Compartment Iliopsoas Release for Iliopsoas Impingement After Primary Total Hip Arthroplasty.

Anterior iliopsoas (IP) impingement after total hip arthroplasty is an underrecognized and continued cause for postoperative pain. There are multiple etiologies for this impingement from cup positioning and sizing to changes in the leg length, and offset must be evaluated to confirm no need for implant revision. Additionally, tension of the IP tendon can be increased in patients with diminished spinal mobility, either from prior fusion or with increasing age. Managing this surgically after failing conservative treatment options is best done arthroscopically to prevent additional large, open procedures that place the arthroplasty at unnecessary risk of infection and potential instability. In this article, we describe an arthroscopic technique using fluoroscopy to guide the release of the iliopsoas tendon from the peripheral compartment.

Telemedicine: An Effective Tool for Patient-Physician Communication.

The purpose of this study was to evaluate the effectiveness of telemedicine appointments in a tertiary orthopedic hip clinic during the COVID-19 pandemic, as a substitute for traditional in-person visits. One hundred sixty-three patients had a telemedicine visit from March to September 2020. Patients were divided into two cohorts. The presurgical group included all patients who had not undergone any prior surgical hip procedures. The pre-surgical group was further subdivided into two groups based on the purpose of the visit: conservative treatment and imaging review. Patients who were indicated for surgical treatment from these two groups were identified to assess their compliance with the surgical indication. The effectiveness was measured by assessing whether patients required an in-person visit before the scheduled follow-up after the telemedicine visit for further medical assessment. Fifty (30.7%) men and 113 (69.3%) women had a telemedicine visit during the 6-month period. The mean age was 43.68 (±16.95) years. There were 92 (56.4%) patients in the presurgical group, of whom 41% followed up after indication for conservative treatment and 59% visited to review imaging. From these groups, 27% were indicated for surgical treatment. The postsurgical group contained 71 (43.6%) patients, divided into three groups based on their surgery date: 0 to 3 months (27%), 4 to 12 months (59%), and more than 12 months (14%). All patients were compliant with the scheduled follow-up after their telemedicine visit. This study showed that telemedicine can be an effective tool for patient-physician communication, obviating the need for subsequent follow-up beyond regularly scheduled visits.

Simplified biplanar classification for heterotopic ossification is more predictive of patient-reported outcomes than the Brooker classification after anterior total hip arthroplasty.

BACKGROUND: Heterotopic ossification (HO) commonly occurs after total hip arthroplasty (THA) and can adversely impact clinical outcomes. The purpose of this study is to propose a more reliable HO grading method that is better predictive of patient-reported outcomes (PROs) after THA than the Brooker classification. METHODS: 513 THAs (62 ± 10 years old) were reviewed. The incidence and grade of HO was evaluated using the Brooker grading system and a simplified biplanar classification system (grade 1: ⩾1 cm between bone on both anteroposterior and lateral views, grade 2: <1 cm between bone on either view). The modified Harris Hip Score (mHHS), Forgotten Joint Score (FJS), and visual analogue scale (VAS) for pain were collected at minimum of 2 years after surgery and were compared between HO grades using multiple regression models. RESULTS: The incidence of HO varied by Brooker grade (grade 1, 23.4%; grade 2, 22.4%; grade 3, 7.2%; grade 4, 0%) and biplanar grade (grade 1: 45.6%; grade 2: 7.4%). The biplanar classification demonstrated higher interobserver reliability than the Brooker classification (κ = 0.95 and 0.91, respectively). Brooker grade 3 HO decreased the mHHS by 6.5 (standard error: 2.7) but did not have a significant effect on FJS or VAS. Biplanar grade 2 HO decreased the mHHS by 9.9 (standard error: 2.7), the FJS by 12.9 (standard error: 4.51) and increased the VAS pain score by 0.81 (standard error: 0.35). The Cox test was used to compare the fit of regression models and determined the biplanar classification was a significantly better predictor than the Brooker classification (p < 0.001). CONCLUSIONS: Biplanar grade 2 HO had a significant negative influence on PROs. Contrary to previous literature, these results show clinical significance of non-bridging HO. Compared with the Brooker classification, the biplanar classification has greater interobserver reliability and is more predictive of outcomes after THA.

Outcomes Following Primary Total Hip Arthroplasty With Concomitant Gluteus Medius Repair Using the Direct Anterior Approach.

Outcomes following total hip arthroplasty (THA) with concomitant gluteus medius (GM) repair using the direct anterior approach (DAA) are scarce. The primary purpose of this study was to report patient-reported outcome measures (PROMs) with 2-year follow-up of patients with osteoarthritis and GM tear who underwent primary THA and GM repair through the DAA. The secondary purpose was to compare these outcomes with a benchmark propensity-matched control group who underwent a DAA THA without GM tear. Patients were eligible if they received a primary THA and GM repair via the DAA between January 2015 and October 2018 and had baseline PROMs with 2-year follow-up. Patients were excluded if they had workers' compensation or were unwilling to participate. PROM subanalysis was performed between patients and a propensity-matched control group with DAA THA without GM tear. Fourteen patients were included in the study, all of whom were female. Significant improvement for all PROMs and high rate of achieving the minimal clinically important difference (MCID) at 2-year follow-up were reported. All patients were propensity-matched to 28 patients for sex, age, and body mass index. Preoperative PROMs between groups were similar, and both groups reported comparable improvement, satisfaction, and MCID achievement at 2-year follow-up. Primary THA with concomitant GM repair using the DAA yielded good functional outcomes and a high rate of MCID achievement at 2-year follow-up. Based on these results, the DAA can be used safely to address symptomatic GM tears during THA. Furthermore, these outcomes were comparable to a propensity-matched control group without GM tear.

The Circumferential Femoroplasty: An All-Arthroscopic Technique for Addressing a Challenging Hip Deformity.

Femoroacetabular impingement is recognized as a common cause of hip pain. Cam-type femoroacetabular impingement results from abnormal contact between an aspherical femoral head and the acetabular rim during hip range of motion, leading to labral tearing, cartilage damage, and, eventually, osteoarthritis. Arthroscopic correction of this bony deformity has been well described, particularly in the anterolateral quadrant of the femoral neck. Some deformities extend well beyond this quadrant, involving most or all of the circumference of the femoral neck, making arthroscopic decompression a challenge. We present a post-less, all-arthroscopic technique for performing a circumferential cam decompression using 3-dimensional preoperative planning software and interactive fluoroscopy-integrated computer vision interface.

Elite Female Athletes Demonstrate a Comparable Improvement in Midterm Patient-Reported Outcome Scores and Rate of Return to Sport Compared With Elite Male Athletes After Hip Arthroscopic Surgery: A Sex-Based Comparison in Professional and Collegiate Athletes.

BACKGROUND: Few studies have compared outcomes, return to sport (RTS), and continuation of sport (CTS) after primary hip arthroscopic surgery between matched groups of male and female athletes with a minimum 5-year follow-up. PURPOSE: (1) To report minimum 5-year patient-reported outcome (PRO) scores as well as RTS and CTS rates for elite female athletes undergoing hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS) and (2) to compare clinical results with those of a matched control group of elite male athletes. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data were prospectively collected and retrospectively reviewed for elite (collegiate or professional) female athletes who underwent primary hip arthroscopic surgery for FAIS between March 2009 and March 2016. Inclusion criteria were preoperative and minimum 5-year scores for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia, previous ipsilateral hip surgery/conditions, and those unwilling to participate. Rates of achieving the minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and maximum outcome improvement satisfaction threshold (MOIST) were recorded in addition to RTS. CTS was also recorded and defined as athletes reporting continued sport activity at a minimum 5-year follow-up after initially reporting returning to sport. Elite female athletes were propensity matched in a 1:1 ratio to elite male athletes for comparison. RESULTS: A total of 81 hips in elite female athletes that underwent primary hip arthroscopic surgery met the inclusion criteria, and follow-up was available for 65 hips (80.2%) at a mean of 67.6 ± 6.5 months, with a mean age of 24.3 ± 6.8 years. Female athletes demonstrated significant improvements in all recorded PRO scores; achieved the MCID, PASS, and MOIST at high rates; returned to sport at a rate of 80.4%; and continued sport at a rate of 97.1%. Female athletes demonstrated lower preoperative PRO scores compared with male athletes, but postoperative PRO scores; improvements in scores; rates of achieving the MCID, PASS, MOIST; and RTS and CTS rates were similar between female and male athletes. CONCLUSION: Elite female athletes undergoing primary hip arthroscopic surgery for FAIS demonstrated favorable PRO scores and high RTS and CTS rates at a minimum 5-year follow-up. These results were comparable with those of a propensity-matched control group of elite male athletes.

Hip Arthroscopy Results in Similar Short-Term Function Compared to Total Hip Arthroplasty in Patients of Similar Demographic Profiles.

Purpose: To review short-term functional outcomes in patients who underwent hip arthroscopy and to compare their outcomes to those of a demographically similar cohort who underwent total hip arthroplasty (THA). Methods: Data were prospectively collected and retrospectively reviewed for patients undergoing hip arthroscopy (SCOPE) between April 2008 and October 2015. SCOPE patients were included if they were ≥35 years, had preoperative and postoperative 2-year follow-up, and had no prior hip condition or ipsilateral hip surgery. SCOPE patients were matched 1:1 to a demographically similar cohort of patients who underwent THA at our institution. Matching criteria included similar age (within 5 years), gender, and body mass index (within 5). SCOPE patients were assessed with modified Harris Hip Score (mHHS), non-arthritic hip score, and visual analogue scale (VAS). THA patients were assessed with mHHS, forgotten joint score, and VAS. Results: Sixty-seven patients were included in each cohort. Patients who underwent hip arthroscopy for management of labral tears achieved nearly equivalent mHHS, Health Survey Short Form (SF-12) Mental, SF-12 Physical, Veterans RAND 12 Item Health Survey (VR-12) Mental, VR-12 Physical scores at latest follow-up compared to demographically similar patients who underwent THA. There was no significant difference in mHHS scores (SCOPE = 82.9 ± 16.4 vs THA = 87.3 ± 15, P = .095) between the 2 group groups. In addition, average patient satisfaction on a 10-point scale was 8.1 for the SCOPE cohort and 8.8 for the THA cohort (P = .052). Conclusions: Our results show that hip arthroscopy, when performed in patients with the appropriate indications, can lead to comparably excellent outcomes as total hip arthroplasty with significant pain relief at short term follow-up. Level of Evidence: Level III, retrospective cohort study.

X-Grab: An Arthroscopic Maneuver to Efficiently and Accurately Track the Post for Knot Tying.

Numerous studies have analyzed techniques for producing reliable and efficient arthroscopic knots. All aspects have been explored, from the biomechanics and strength to the ability to teach and replicate at all levels of training. This technique article describes an additional maneuver (X-grab) for efficiently marking the post side of the arthroscopic knot without having to do this separately outside of the joint. This is most useful for procedures such as rotator cuff repair and capsular repair or plication in hip arthroscopy in which the location of the knot (i.e., the post) is critical. The aim of this Technical Note is to describe the X-grab maneuver, which shortens this process to a single step, limiting the see-sawing of sutures and over-instrumentation of the joint seen with other techniques.

Outcomes Among Athletes Versus Nonathletes After Arthroscopic Management of Femoroacetabular Impingement.

This study synthesizes and reports patient-reported outcomes (PROs) among athletes vs nonathletes after hip arthroscopy for femoroacetabular impingement. A systematic review was performed in November 2020 with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) process. We included studies that reported PROs for athletes vs nonathletes. We excluded articles that did not contain full text, that were not in English, and that included level IV evidence. Four studies reporting on a total of 294 athletes and 230 nonathletes were included. Of these studies, 3 found superior outcomes among athletes, and 1 found that athletes recovered faster, but nonathletes had equivalent outcomes at later follow-up. Athletes and nonathletes showed significant improvements in PROs; however, athletes showed a trend toward superior PROs. Thus, pre-operative athletic activity is associated with favorable outcomes after hip arthroscopy. [Orthopedics. 2022;45(6):e288-e294.].

Outcomes of Staged Bilateral Hip Arthroscopic Surgery in the Context of Femoroacetabular Impingement Syndrome: A Nested Matched-Pair Control Study Focusing on the Effect of Time Between Procedures.

BACKGROUND: Bilateral hip symptoms from femoroacetabular impingement syndrome (FAIS) are a common finding in patients regardless of athletic involvement. Oftentimes, patients and surgeons choose to stage bilateral hip arthroscopic surgery. PURPOSE/HYPOTHESIS: The purpose of this study was (1) to compare minimum 2-year outcomes between patients who underwent staged bilateral hip arthroscopic surgery for FAIS to a propensity score-matched control group that underwent unilateral hip arthroscopic surgery and (2) to investigate the effect of time between bilateral procedures on patient-reported outcomes (PROs). We hypothesized that, after bilateral hip arthroscopic surgery, the improvement in outcomes would be similar to that after unilateral hip arthroscopic surgery and the time duration between bilateral procedures would not affect the final outcome. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data were retrospectively reviewed on a consecutive series of patients who underwent primary hip arthroscopic surgery at our institution between June 2008 and November 2017. Patients who underwent bilateral hip arthroscopic surgery with minimum 2-year PROs for the modified Harris Hip Score (mHHS), the Nonarthritic Hip Score (NAHS), the Hip Outcome Score-Sports Specific Subscale (HOS-SSS), patient satisfaction, and a visual analog scale (VAS) for pain were included. The study group was matched 1:1 based on age, sex, and body mass index to a control group that only required unilateral hip arthroscopic surgery. Additionally, a subanalysis was performed on the study group to determine the effect of time between arthroscopic procedures. Rates of achieving the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) for the mHHS and HOS-SSS were determined. The P value was set at <.05. RESULTS: A total of 205 patients (410 hips) were included. The mean age and body mass index of the study group were 32.3 ± 13.2 years and 25.0 ± 5.1, respectively. All 410 hips that met the inclusion criteria were matched. There were no significant differences in patient, radiographic, or procedural data. A significant and comparable improvement was reported for all PRO measures and the VAS (P < .0001) in both groups. Similarly, rates of achieving the MCID and PASS were comparable. After dividing the study group based on whether the contralateral procedure was performed <3 months or >3 months after the first procedure, it was determined that patients had a significant improvement and favorable outcomes regardless of time between bilateral procedures. CONCLUSION: Patients who underwent unilateral and bilateral hip arthroscopic surgery for FAIS had a significant and comparable improvement in PROs at a minimum 2-year follow-up. A time interval of <3 months or >3 months between bilateral procedures did not affect PROs.

Comparison of Outcomes Between Nonsmokers and Patients Who Discontinued Smoking 1 Month Before Primary Hip Arthroscopy: A Propensity-Matched Study With Minimum 2-Year Follow-up.

Background: Cigarette smoking has been shown to negatively affect outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). The effect of cessation of cigarette smoking before surgery has not been well established. Purposes: (1) To report minimum 2-year patient-reported outcomes (PROs) of former smokers who underwent primary hip arthroscopy for FAIS and (2) to compare these results with those of a propensity-matched control group of nonsmokers. Study Design: Cohort study; Level of evidence, 3. Methods: Data were collected for all patients who underwent primary hip arthroscopy for FAIS between December 2008 and November 2017. Patients were eligible if they indicated that they had previously smoked cigarettes but had quit smoking at least 1 month before surgery and had minimum 2-year postoperative outcomes for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and visual analog scale (VAS) for pain. The percentage of hips achieving the minimal clinically important difference (MCID) were recorded. The study group was then propensity matched in a 1:1 ratio by age, sex, and body mass index (BMI) to patients who had never smoked. Results: A total of 83 former-smoking patients (84 hips; age, 45.0 ± 13.5 years) were included at a median follow-up of 38.6 months (interquartile range, 27.5-48.2 months); all patients had stopped smoking at a mean ± standard deviation of 14.3 ± 24.5 months preoperatively. Former smokers demonstrated significant improvement from preoperatively to the minimum 2-year follow-up for all recorded PROs (P < .001 for all) and achieved the MCID for the mHHS, NAHS, and VAS at favorable rates (75.0%-81.6%). Logistic regression analysis did not identify a significant relationship between cessation time and rates of achieving MCID for mHHS, NAHS, or VAS. When compared with 84 never-smokers (84 hips), the former smokers demonstrated similar preoperative scores, postoperative scores, and improvement on all recorded PROs (P > .05 for all). Both groups achieved MCID for mHHS, NAHS, and VAS at similar rates and demonstrated similar rates of revision surgery. Conclusion: Former smokers who underwent primary hip arthroscopy for FAIS demonstrated significant improvement in PROs at minimum 2-year follow-up. When compared with a propensity-matched control group of never-smokers, they achieved similar postoperative PROs and rates of achieving psychometric thresholds.

Maximal Outcome Improvement Willingness Thresholds Are Predictive of a Patient's Willingness to Undergo the Same Surgery, in Retrospect, Given the Known Outcome of Their Primary Hip Arthroscopy.

Purpose: To determine the percent maximal outcome improvement willingness thresholds (MOWTs) for the Nonarthritic Hip Score (NAHS) and the visual analog scale (VAS) for pain that were associated with a patient's willingness to undergo surgery, in retrospect, given the known outcome of their primary hip arthroscopy with concomitant endoscopy for gluteus medius (GM) tear repair. Methods: An anchor question was provided to patients who underwent primary hip arthroscopy for femoroacetabular impingement syndrome with concomitant endoscopic GM tear repair between April 2008 to April 2020. Patients were included if they answered the anchor question and had baseline and postoperative minimum 1-year follow-up scores for the NAHS and VAS. Patients were excluded if they had a previous ipsilateral hip surgery, Tönnis grade >1, hip dysplasia, previous hip conditions, or a preoperative score that was already at the maximum value for the NAHS and VAS scores. Receiver operating characteristic (ROC) analysis was used to determine the MOWT. Significance was indicated by a P value <.05. Results: A total of 107 patients (107 hips) were included, with 101 (94.4%) females and 6 (5.6%) males. The average age and body mass index was 56.20 ± 9.88 years and 28.80 ± 4.92 kg/m2, respectively. The average follow-up time was 54.89 ± 29.52 months. The ROC analysis determined that the MOWT for the mHHS and VAS were 54.7%, and 62.6%, respectively. The probability of a patient being willing to undergo surgery again if they met the MOWT was 85.8% and 85.6% for the NAHS and VAS, respectively. Conclusion: The MOWTs that were predictive of willingness to undergo surgery again following primary hip arthroscopy with concomitant endoscopy for GM tear repair were 54.7% and 62.6% for the NAHS, and VAS, respectively. Clinical Relevance: Outcome assessment has been a point of increasing emphasis in hip preservation surgery. Having a tool to measure whether patients would go through the process of surgery again knowing their current outcome status is important to understanding outcomes after surgery.

Outcomes and Return-to-Sport Rates for Elite Athletes With Femoral Retroversion Undergoing Hip Arthroscopy: A Propensity-Matched Analysis With Minimum 2-Year Follow-up.

Background: Return to sports (RTS) and patient-reported outcomes (PROs) for elite athletes with femoral version abnormalities undergoing hip arthroscopy have not been well established. Purposes: To (1) report minimum 2-year PROs and RTS rates in elite athletes with femoral retroversion who underwent primary hip arthroscopy and (2) compare clinical results to those of a propensity-matched control group of elite athletes with normal femoral version who underwent primary hip arthroscopy. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected and retrospectively reviewed for elite (professional and collegiate) athletes with femoral version <5°, as measured on magnetic resonance imaging scans, who underwent hip arthroscopy for femoroacetabular impingement syndrome between March 2010 and April 2018. Inclusion criteria were preoperative and minimum 2-year follow-up PROs for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia, and previous ipsilateral hip surgery or conditions. Rates of achieving the minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and maximum outcome improvement satisfaction threshold were recorded in addition to RTS. Athletes with retroversion were propensity matched in a 1:2 ratio to elite athletes with normal femoral version (5°-20°) for comparison. Results: A total of 33 elite athletes (33 hips) with femoral retroversion who underwent hip arthroscopy met the inclusion criteria, and follow-up was available for 30 hips in 30 athletes (90.9%) at an average of 36.1 ± 25.6 months. Elite athletes with femoral retroversion demonstrated significant improvements in all recorded PROs, achieved the MCID and PASS for the HOS-SSS at high rates (86.7%), and returned to sports at a rate of 83.3%. PROs, rates of achieving MCID and PASS for the HOS-SSS, and RTS rates were similar between the study and propensity-matched control group. Conclusion: Elite athletes with femoral retroversion undergoing primary hip arthroscopy demonstrated favorable PROs and high RTS rates at a minimum 2-year follow-up. These results were comparable with those of a propensity-matched control group of elite athletes with normal femoral version.

Outcomes After Primary Hip Arthroscopy in Athletes Older Than 40 Years Compared With Nonathletes.

BACKGROUND: Master athletes (MAs), or athletes older than 40 years, make up a patient population whose outcomes after primary arthroscopic hip surgery are largely unknown. PURPOSE: To report minimum 2-year outcomes of MAs after primary hip arthroscopy and compare their results to a propensity-matched nonathlete (NA) control group. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data were prospectively collected between February 2008 and April 2019 and retrospectively reviewed for all patients who underwent primary hip arthroscopy. Patients were included if they were older than 40 years and had preoperative data for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale score for pain. MAs reported participating in organized sports competition within 1 year before surgery and were propensity matched to a control group of patients who did not report participating in organized sports competition (NAs). Patient characteristics, radiographic and intraoperative findings, surgical procedures performed, and patient-reported outcome measures (PROMs) were reported and compared between the groups. The rates of achieving the minimal clinically important difference and maximum outcome improvement satisfaction threshold were recorded. RESULTS: A total of 366 hips were eligible; 328 (89.6%) had adequate follow-up data. 328 patients met inclusion criteria but 88 were not included due to the restrictions of the propensity score match ratio. Of these, 80 hips (76 patients) were classified as MAs (mean age, 48.9 ± 6.2 years) and were propensity matched 1:2 to an NA control group. Groups were comparable for baseline demographic and radiographic parameters, intraoperative findings, and procedures performed. MAs had significantly better baseline and minimum 2-year PROM scores (P < .05), higher satisfaction (P = .01), and higher rates of achieving clinically meaningful improvement across all the outcome tools used (P < .05). MAs, when compared with NAs, had lower rates of secondary arthroscopy (0% vs 7.5%, respectively; P = .001) and conversion to total hip arthroplasty (12.5% vs 26.9%, respectively; P = .011). CONCLUSION: MAs demonstrated favorable outcomes after primary hip arthroscopy. When compared with a propensity score-matched control group of NA patients, MAs demonstrated better preoperative and postoperative PROMs, higher rates of clinically meaningful improvement, and lower rates of secondary arthroscopy and conversion to total hip arthroplasty. Absolute improvements in PROM scores were similar between the groups.

Intra-articular Damage and Patient Outcome Comparison Between Athletes and Nonathletes After Hip Arthroscopy.

BACKGROUND: The body of literature comparing hip arthroscopy between athletes and nonathletes is relatively scarce. Analyzing these groups can help to shed light on the severity of intra-articular damage and end-stage osteoarthritis that may result from participation in strenuous activities. PURPOSE: (1) To compare the intra-articular damage at the time of hip arthroscopy between athletes and nonathletes, and (2) to compare the pre- and postoperative outcomes between the groups. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients were considered eligible for analysis if they had received a primary hip arthroscopy between August 2008 and June 2018, were participating in competitive athletics, and had preoperative baseline scores and minimum 2-year follow-up for the following patient-reported outcomes: modified Harris Hip Score, Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale, and visual analog scale. Propensity score matching was used to match eligible patients in a 1:1 ratio to patients who were not participating in any sports greater than a recreational level before surgery. RESULTS: A total of 234 patients were included. There were no significant differences in the severity of labral tears, ligamentum teres tears, or cartilage damage (P > .05). The procedures performed between cohorts were similar (P > .05). The athlete population had higher preoperative means scores for the modified Harris Hip Score and NAHS (each P < .001). Likewise, the athlete population had higher postoperative means scores for the NAHS, Hip Outcome Score-Sports Specific Subscale, and visual analog scale (P = .031, P = .030, and P = .032, respectively). Additionally, the athlete cohort reported higher minimum 2-year outcomes than the nonathlete cohort for the 12-Item Short Form Health Survey (mental component; P = .003) and Veterans RAND 12-Item Health Survey (mental component, P = .032; physical component, P = .005). CONCLUSION: At the time of hip arthroscopy, athletes demonstrate similar intra-articular damage to their nonathlete counterparts. Given their higher preoperative scores, it is possible that athletes better tolerate the damage to the hip joint. Despite their strenuous activities and potentially higher tolerance to pain, athletes should not necessarily be expected to have greater severity of intra-articular pathology.

Hip Pain Increases With Age and Experience Level in Adult Karate Athletes: A Statewide Survey Study.

Purpose: To investigate the prevalence of hip pain from labral tears and femoroacetabular impingement (FAI) in karate athletes using a statewide online survey. Methods: An anonymous electronic survey was distributed via Qualtrics to all registered members of a statewide karate organization who were a purple belt or higher. Basic demographic information was collected as well as belt level, competitive level, and information regarding hip pain and treatment for hip pain. Microsoft Excel was used to store and analyze data. Results: Of 180 respondents, 123 (68.3%) never had hip pain when practicing karate, and 54 (30.0%) had hip pain at some point in their karate career. Three subjects did not provide an answer and were excluded. Furthermore, of the symptomatic individuals, 52 reported the location of their hip pain, whereas 2 subjects did not. Of the symptomatic individuals (54), 32 had formal diagnoses by a medical professional, 4 (12.5%) were diagnosed with FAI of the hip, 6 (18.8%) diagnosed with a hip labral tear, 3 (9.4%) diagnosed with hip bursitis, 3 (9.4%) diagnosed with hip arthritis, and 16 (50%) had other diagnoses. The remaining 22 participants have not received a formal diagnosis by a medical professional. Conclusions: The prevalence of hip pain in karate athletes in this survey was lower compared to athletes of other martial arts and kicking sports. No differences in the percentage of injuries were found between sex and years practiced; however a higher incidence of hip pain was found between elite status and age group. When evaluating hip pain in the karate population, orthopaedic surgeons should maintain an index of suspicion for FAI and hip labral tears. Level of Evidence: Level IV, retrospective cross-sectional study.

Effect of Cigarette Smoking on Midterm Outcomes After Arthroscopic Surgery for Femoroacetabular Impingement Syndrome: A Propensity-Matched Controlled Study With Minimum 5-Year Follow-up.

Background: There is limited literature evaluating patient-reported outcomes (PROs) in cigarette smokers undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS) at midterm follow-up. Purpose: (1) To report minimum 5-year PROs for cigarette-smoking patients who underwent primary hip arthroscopy for FAIS and (2) to compare these results with a propensity-matched control group of never-smoking patients. Study Design: Cohort study; Level of evidence, 3. Methods: Data were collected for all patients who underwent primary hip arthroscopy for FAIS between June 2009 and March 2016. Patients were eligible if they indicated that they smoked cigarettes within 1 month of surgery and had minimum 5-year postoperative outcomes for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale (HOS-SSS), and International Hip Outcome Tool-12 (iHOT-12). The percentages of patients achieving the Patient Acceptable Symptom State (PASS) and maximum outcome improvement satisfaction threshold were recorded. The study group was then propensity matched in a 1:2 ratio to patients who had never smoked for comparison. Results: Included were 35 patients (35 hips) with a mean age of 39.4 ± 13.0 years and mean follow-up of 64.6 ± 4.1 months. These patients demonstrated significant improvement from preoperatively to a minimum 5-year follow-up for all recorded PROs (P < .05). When compared with 70 control patients (70 hips), smoking patients demonstrated significantly worse preoperative scores for all PROs (P < .05). Study patients also demonstrated worse minimum 5-year scores for all recorded PROs compared with control patients, which did not reach statistical significance but trended toward significance for HOS-SSS (70.4 vs 81.9; P = .076) and iHOT-12 (74.7 vs 82.2; P = .122). Smoking patients also trended toward lower rates of achieving PASS for the iHOT-12 compared with never-smoking patients (50.0% vs 68.2%; P = .120). Conclusion: Patients who smoked cigarettes and underwent primary hip arthroscopy for FAIS demonstrated significant improvement in PROs at a minimum 5-year follow-up. When compared with a propensity-matched control group of never-smokers, they trended toward lower postoperative HOS-SSS and iHOT-12 scores and lower rates of achieving PASS on the iHOT-12.
