Preparing Students to Deliver Care to Diverse Populations.

The purpose of this study was to increase student exposure to diverse patients using patient ID cards in problem-based learning (PBL) at Case Western Reserve University (CWRU). The pre-clerkship curriculum capitalizes on facilitated small-group, case-based discussions to promote inquiry and learning of the foundational sciences. Quantitative and qualitative results supported a finding of added value to case-discussions and the humanization of case-patients. The inclusion of the patient ID cards resulted in most students indicating that it helped them learn about and prepare to care for their future population of diverse patients. The patient ID cards will allow us to develop specific learning objectives about the demographics to increase learning about diverse patient care.

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.

How has arthroscopic management of the iliopsoas evolved, and why? A survey of high-volume arthroscopic hip surgeons.

The rapid growth of hip preservation has left surgeons following trends based on limited, or even anecdotal, evidence in certain circumstances. A consensus as well as high-level research on how best to manage the iliopsoas is lacking. Arthroscopic treatment of the iliopsoas may be an example of how treatment patterns and trends can shift with limited evidence-based medicine. A cross-sectional survey of 16 high-volume hip preservation surgeons was conducted to gather perspectives and opinions on how and why the arthroscopic management of the iliopsoas has evolved. All participants completed the survey in person and anonymously. Of the surveyed surgeons, the mean career hip preservation volume was 1031.25 cases (250 to >3000) with an average annual volume of 162.08 cases (75-400). Of the surveyed surgeons' caseload, 16.1% involved an iliopsoas tenotomy or fractional lengthening mostly commonly (75%) for recalcitrant internal snapping. Labral repair/reconstruction is performed concomitantly 87.5% of the time. Seventy-five percent of surgeons indicated a decrease in frequency of iliopsoas tenotomy over the course of their practice most commonly (56.3%) because of hip flexion weakness; however, 0% of the surgeons could cite literature evidence to support their practices. Perceived poor outcomes in individual practices was the most common (56.3%) source of this complication. Surgeons were less inclined to perform tenotomy on patients with borderline dysplasia (75%) or ligamentous laxity (56.3%).

Identifying the Most Successful Procedures in Hip Arthroscopy.

Hip arthroscopy for femoral and acetabular pathologies has increased dramatically. However, there is little literature analyzing procedures as predictors of revision arthroscopy or arthroplasty. From February 2008 to November 2015, patients undergoing hip arthroscopy for a labral tear with minimum 2-year follow-up and between 18 and 60 years old were retrospectively reviewed. Those with previous surgeries, Tönnis grade greater than 1, and previous hip conditions were excluded. Follow-up was obtained for 1118 patients (1249 hips; 81.7%) with a mean age of 38.7 years (range, 18.0-60.0 years), mean body mass index of 26.4 kg/m2 (range, 16.3-48.9 kg/m2), and mean follow-up of 50.2 months (range, 24.0-111.9 months). A total of 122 (9.8%) patients converted to total hip arthroplasty (mean, 35.3 months; range, 1.4-95.2 months). Multivariate analysis for predictors of total hip arthroplasty found age at surgery (hazard ratio, 1.064/y; P<.05), body mass index (nonlinear; P<.05), labral debridement (HR, 1.558; P=.03), and notchplasty (HR, 2.128; P<.05), with trochanteric bursectomy (HR, 0.367; P<.05) identified as associated with higher survivorship. A total of 124 (9.9%) patients underwent revision hip arthroscopy at a mean of 21.7 months (range, 0.10-83.3 months). Multivariate analysis for predictors of revision surgery found workers' compensation (HR, 3.352; P<.05), capsular repair (HR, 1.950; P<.05), and femoral head microfracture (HR, 2.844; P=.04) to be significant, with age at date of surgery (HR, 0.973/y; P<.05) and femoral head chondroplasty (HR, 0.241; P=.05) associated with higher survivorship. Understanding risk factors for conversion to total hip arthroplasty or revision is paramount during discussions with patients. [Orthopedics. 2020;43(3):173-181.].

Does Femoral Retroversion Adversely Affect Outcomes After Hip Arthroscopy for Femoroacetabular Impingement Syndrome? A Midterm Analysis.

PURPOSE: To report 5-year outcomes of arthroscopic treatment of femoroacetabular impingement syndrome in patients with femoral retroversion compared with a control group of patients with normal femoral anteversion. METHODS: Data were prospectively collected and retrospectively reviewed for all patients who underwent hip arthroscopy between August 2008 and April 2013. Patients were included in analysis if they underwent hip arthroscopy during this period and had femoral version ≤0° calculated using magnetic resonance imaging. Exclusion criteria included prior ipsilateral hip conditions/surgeries or Tönnis grade >1. These patients were pair matched with patients having femoral anteversion between 10° and 20° based on gender, body mass index ± 10, and age ± 10 years. Patient-reported outcomes (PROs) were collected at 3 months and 1 year postoperatively and annually thereafter. An a priori power analysis was performed. RESULTS: A total of 59 patients were identified as the experimental group out of 69 eligible for inclusion (86%). All 59 patients were matched, with a mean age of 37.4 years and mean body mass index of 26.9. Twenty patients were female, and 39 were male. These patients demonstrated significant improvement from their preoperative state in all patient-reported outcomes and visual analog score scores (P < .001). Thirty-eight patients met the threshold for minimal clinically important difference, and 35 achieved patient acceptable symptomatic state for the modified Harris Hip Score questionnaire. Seven patients converted to total hip replacement. No differences were noted between retroverted and control patients in any of the outcome measures collected, in pain or satisfaction ratings, in the frequency of or duration to secondary surgeries or in complication rate (P > .05). CONCLUSIONS: Patients with femoral retroversion demonstrated significantly higher outcomes at minimum 5-year follow-up after undergoing arthroscopic hip surgery. These outcomes were not different from those of patients with normal femoral version. While femoral retroversion should not be considered a contraindication to hip arthroscopy, it should be carefully considered as a factor in patient selection and surgical planning. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Primary Hip Arthroscopic Surgery With Labral Reconstruction: Is There a Difference Between an Autograft and Allograft?

BACKGROUND: Labral reconstruction has been described as a solution for the irreparable labrum. Initial techniques employed autografts, while more recent procedures have utilized allografts. No study, to our knowledge, has compared graft types. PURPOSE: To compare outcomes between patients who underwent primary labral reconstruction with a hamstring allograft versus hamstring autograft. HYPOTHESIS: No significant differences in outcomes will be found between patients who underwent primary labral reconstruction with an allograft versus autograft. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data from September 2010 to March 2015 were reviewed. Inclusion criteria were primary hip arthroscopic surgery with labral reconstruction using either a hamstring allograft (ALLO group) or autograft (AUTO group), with minimum 2-year follow-up scores for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports-Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. Exclusion criteria were previous ipsilateral hip surgery, previous hip conditions, preoperative Tönnis osteoarthritis grade >1, and workers' compensation claims. Significance was set at P = .05. RESULTS: Twenty-nine patients (29 hips) were included (85.3% follow-up). There were 17 patients (17 hips) in the ALLO group and 12 patients (12 hips) in the AUTO group. All patient-reported outcome scores demonstrated significant improvements at latest follow-up except for the mHHS for the AUTO group (P = .064). Comparisons between the ALLO and AUTO groups at the preoperative and latest follow-up time points showed no significant differences (preoperative mean [range]: mHHS, 67.5 [33.0-100.0] and 65.8 [29.0-96.0], respectively [P = .826]; NAHS, 65.6 [26.3-92.5] and 58.5 [35.0-79.0], respectively [P = .322]; HOS-SSS, 43.7 [12.5-100.0] and 40.1 [19.0-78.0], respectively [P = .707]) (latest follow-up mean [range]: mHHS, 86.4 [56.0-100.0] and 81.4 [57.0-100.0], respectively [P = .46]; NAHS, 87.7 [60.0-100.0] and 82.4 [56.3-100.0], respectively [P = .396]; HOS-SSS, 81.7 [0.0-100.0] and 70.9 [27.8-100.0], respectively [P = .423]). CONCLUSION: Primary arthroscopic hip labral reconstruction yielded improvements in patient-reported outcome scores and high patient satisfaction. In this small series, no differences were found in clinical outcomes between hamstring allografts and autografts. Based on these results, hamstring allografts and autografts may be considered comparable graft choices for primary reconstruction. Because of the avoidance of donor site morbidity and the possible increase in patient satisfaction, allografts may be the preferred choice in a surgical setting when they are accessible.

Effect of Cigarette Smoking on Patient-Reported Outcomes in Hip Arthroscopic Surgery: A Matched-Pair Controlled Study With a Minimum 2-Year Follow-up.

BACKGROUND: The rate of hip arthroscopic surgery has recently increased; however, there is limited literature examining patient-reported outcomes (PROs) in cigarette smokers. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate whether smoking status for patients undergoing hip arthroscopic surgery affects clinical findings and PRO scores. We hypothesized that patients who smoke and undergo primary hip arthroscopic surgery will have similar clinical examination findings and preoperative and postoperative PRO scores compared with nonsmoking patients. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data were collected on all patients who underwent primary hip arthroscopic surgery from February 2008 to July 2015. A retrospective analysis of the data was then conducted to identify patients who reported cigarette use at the time of the index procedure. Patients were matched 1:2 (smoking:nonsmoking) based on sex, age within 5 years, labral treatment (repair vs reconstruction vs debridement), workers' compensation status, and body mass index within 5 kg/m2. All patients were assessed preoperatively and postoperatively using 4 PRO measures: the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sport-Specific Subscale (HOS-SSS), and International Hip Outcome Tool-12 (iHOT-12). Pain was estimated using a visual analog scale. Satisfaction was measured on a scale from 0 to 10. Significance was set at P < .05. RESULTS: A total of 75 hips were included in the smoking group, and 150 hips were included in the control group. Preoperatively, the smoking group had significantly lower PRO scores compared with the control group for the mHHS, NAHS, and HOS-SSS. Both groups demonstrated significant improvement from preoperative levels. A minimum 2-year follow-up was achieved, with a mean of 42.5 months for the smoking group and 47.6 months for the control group (P = .07). At the latest follow-up, the smoking group reported inferior results for all outcome measures compared with controls. The improvement in PRO scores and rates of treatment failure, revision arthroscopic surgery, and complications was not statistically different between the groups. CONCLUSION: Patients who smoke had lower PRO scores preoperatively and at the latest follow-up compared with nonsmokers. Both groups demonstrated significant improvement in all PRO scores. These results show that while hip arthroscopic surgery may still yield clinical benefit in smokers, these patients may ultimately achieve an inferior functional status. To optimize results, physicians should advise patients to cease smoking before undergoing hip arthroscopic surgery.

Outcomes of Hip Arthroscopy With Concomitant Periacetabular Osteotomy, Minimum 5-Year Follow-Up.

PURPOSE: To report minimum 5-year follow-up results of concomitant hip arthroscopy followed by periacetabular osteotomy (PAO) to treat acetabular dysplasia and intra-articular pathology, such as femoroacetabular impingement syndrome and labral tears. METHODS: Data were prospectively collected from October 2010 to December 2012. Patients were included in this study if they underwent concomitant hip arthroscopy and PAO and if they had preoperative scores documented for the following measures: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports-Specific Subscale (HOS-SSS), and pain on a visual analog scale (VAS). Patients who underwent reverse PAO to address acetabular retroversion were excluded. Follow-up was considered complete with these outcomes collected after surgery, as well as the abbreviated International Hip Outcome Tool and patient satisfaction on a 0-10 scale. Significance was set at P = .05. RESULTS: Sixteen patients were eligible, all of whom had complete follow-up at a minimum of 5 years after surgery. There were 13 female subjects. The average age of the patients was 23.5 ± 6.8 years (range, 12.3-35.3 years), and the average body mass index was 24.3 ± 5.6 (range, 14.8-34.2). The mean lateral center-edge angle increased from 14.2° to 31.8° (P < .0001), and the anterior center-edge angle increased from 11.9° to 28.6° (P < .0001). The Tönnis angle of acetabular inclination decreased from 19.3° to 2.6° (P < .0001). The alpha angle decreased from 55.7° to 41.0° (P < .0001). All preoperative radiographs were Tönnis ≤1, and there was no progression of arthritis in radiographs taken at the latest clinical visit. All patient-reported outcomes scores demonstrated significant improvement from preoperative baseline to the minimum 5-year follow-up scores (mHHS, P < .001; NAHS, P < .001; HOS-SSS, P = .001). The VAS score decreased from a preoperative mean of 5.8 to 3.1 at the latest follow-up (P = .007). No conversion to total hip arthroplasty was reported. CONCLUSIONS: Concomitant hip arthroscopy and PAO appears to be a safe and effective procedure with favorable mid-term outcomes that are durable compared to the short-term. LEVEL OF EVIDENCE: Level IV, case series.

The Effect of Complete Tearing of the Ligamentum Teres in Patients Undergoing Primary Hip Arthroscopy for Femoroacetabular Impingement and Labral Tears: A Match-Controlled Study.

PURPOSE: To compare the patient-reported outcomes scores (PROs) of patients with femoroacetabular impingement (FAI), labral tears, and complete ligamentum teres (LT) tears to a matched-pair control group with intact LTs, as well as to report the relative risk of total hip arthroplasty (THA) conversion. METHODS: Data between February 2008 and April 2015 were retrospectively reviewed. Patients undergoing hip arthroscopy included those who had complete LT tear, labral tears, FAI, and minimum 2-year follow-up with modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), International Hip Outcome Tool-12 (iHOT-12), and visual analog scale (VAS). Patients were excluded for Tönnis osteoarthritis grade >1, previous hip conditions or surgeries, and Worker's Compensation claims. Patients with full LT tears were matched in a 1:3 ratio with patients without LT tears based on age at surgery ± 5 years, sex, body mass index ± 5, capsular treatment, and acetabular Outerbridge grade. Revision surgeries and conversions to THA were documented. Relative risk for conversion to THA was determined (P = .05). RESULTS: Eighteen patients (18 hips) had minimum 2-year follow-up and were eligible for matching; as described, each study group patient was matched to 3 control patients, resulting in a size of 18 to 54 patients. PROs showed significant improvement in the complete LT tear group with the exception of the HOS-SSS measure. In the intact LT control group, all PROs significantly improved, with no exception. Based on relative risk, patients with complete LT tears were 3 times more likely to require THA than a matched control group. CONCLUSIONS: After hip arthroscopy, patients with FAI and complete LT tears reported significant improvement in PROs. Among hips that did not require THA, functional scores were comparable to a matched control group. However, patients with complete LT tears were 3 times more likely to require an eventual THA than the matched control group. We conclude that patients with complete LT tears should be considered an at-risk population, and that indications and treatment may be refined to incorporate the clinical significance of complete LT tears. LEVEL OF EVIDENCE: Level III, comparative trial, case-control.

Direct Anterior Approach in Total Hip Arthroplasty Leads to Superior Outcomes at 3-Month Follow-up When Compared With the Posterior Approach: A Matched Study Using Propensity Score Analysis.

The purpose of this study was to report and compare early outcomes during the first 3 months of the recovery phase in patients who underwent primary total hip arthroplasty (THA) with direct anterior approach (DAA) and posterior approach (PA). BACKGROUND: The DAA for primary THA has gained popularity within the past few years. Although controversy exists regarding the long-term benefit when compared with the PA, several authors have reported markedly better outcomes in the early recovery weeks, when using DAA. METHODS: For this study, data were prospectively collected and retrospectively reviewed for all primary THAs from March 2014 to October 2017. Included patients underwent primary THA through DAA or PA and had minimum 3-month postoperative measures for the Harris Hip Score, Forgotten Joint Score-12, Veterans RAND 12 Mental (VR-12 Mental), Veterans RAND 12 Physical (VR-12 Physical), 12-Item Short-Form (SF) Survey Mental, 12-Item SF Survey Physical (SF-12 Physical), Visual Analog Scale, and patient satisfaction. An analysis using propensity score matching was done to establish the DAA and PA groups. Matching (1:1 ratio) was conducted based on the following covariates: age, sex, body mass index, and laterality. RESULTS: Twenty-four DAA THA patients were successfully matched using propensity scoring to 24 PA THA patients. The DAA group demonstrated significantly higher scores for the following patient-reported outcome scores: Harris Hip Score, VR-12 Mental, VR-12 Physical, and SF-12 Physical (P = 0.0090, P = 0.0388, P = 0.0063, and P = 0.0132, respectively). CONCLUSION: At 3-month follow-up, both the DAA and PA groups reported favorable outcomes after THA. However, the DAA group scored markedly higher regarding quality-of-life outcomes when compared with a propensity score-matched group of PA patients.

Primary labral reconstruction in patients with femoroacetabular impingement, irreparable labral tears and severe acetabular chondral defects decreases the risk of conversion to total hip arthroplasty: a pair-matched study.

In the presence of severe acetabular cartilage defects, the benefits of labral reconstruction (RECON) versus labral resection (RESEC) have not been determined. Prospectively collected data between October 2008 and December 2016 were retrospectively reviewed. Inclusion criteria were hip arthroscopy, acetabular Outerbridge grade III/IV, irreparable labral tears that underwent RECON or RESEC, and minimum 2-year postoperative measures for the modified Harris Hip Score, Non-Arthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, International Hip Outcome Tool, Patient Satisfaction and Visual Analogue Scale for pain. Exclusion criteria included Tönnis grade >1, previous hip conditions or previous ipsilateral hip surgeries. A 1:1 matched-pair analysis was performed based on age ±5 years, sex, body mass index ±5 kg/m2, Tönnis grade, acetabular microfracture, femoral Outerbridge grade (0 or I compared with II, III or IV). Relative risk (RR) and conversion rate to total hip arthroplasty (THA) were calculated. A total of 38 RECON hips were successfully matched. Both groups demonstrated significant improvements in patient-reported outcomes (PROs). THA conversion was 5.3% and 21.1% for the RECON and RESEC groups, respectively (P = 0.04). RECON was four times less likely to require THA conversion than the RESEC group (RR=4.0; 95% CI 0.91-17.63). In the setting of primary arthroscopic management of femoroacetabular impingement, irreparable labral tears and acetabular chondral lesions of Outerbridge III/IV, patients that underwent RECON and RESEC experienced significant improvement in PROs at minimum 2-year follow-up, and these functional scores were comparable when groups were matched. However, RR and rate to THA conversion were significantly higher in the RESEC group.

The education and training of future hip preservation surgeons: aggregate recommendations of high-volume surgeons.

Hip preservation is one of the fastest growing subspecialties in orthopaedic surgery. Surgical training recommendations and guidelines in this field are lacking. To survey high volume hip preservation surgeons regarding their perspectives on the current and future training of surgeons entering their field, a cross-sectional survey of 16 high-volume hip preservation surgeons was conducted to gather perspectives and opinions on the most appropriate education of future hip preservation surgeons. All participants completed the survey in person and anonymously. Of the surveyed surgeons, the mean career hip preservation volume was 1031.25 cases (250 to >3000) with an average annual volume of 162.08 cases (75-400). The average number of hip arthroscopy cases necessary to competently perform joint access is 19, labral repair is 34, acetabuloplasty/femoroplasty are 54, labral reconstruction is 101 and capsular closure/plication is 53. Fifty-six percent of the surgeons believe mid-career surgeons who have never performed hip preservation surgery should not adopt it as part of their practice. The mean optimal number of cases recommended was 128 hip arthroscopies during a dedicated hip preservation fellowship and 67 hip arthroscopies during a sports medicine fellowship. Surgeons with an interest in hip preservation careers, should strongly consider a 12-month dedicated hip preservation fellowship that provides exposure to at least 128 cases, including open and arthroscopic techniques, hip arthroplasty, and research opportunities. Mid-career surgeons should be cautious about adopting hip preservation into their practice if they have not had prior adequate training.

Modified Shelf Acetabuloplasty Endoscopic Procedure With Allograft for Developmental Hip Dysplasia Treatment.

Hip dysplasia has been identified as one of the leading causes of osteoarthritis. However, hip arthroscopy alone, in the setting of hip dysplasia, remains controversial. In borderline hip dysplasia, with lateral center-edge angle (LCEA) between 18° and 25°, good outcomes have been reported with appropriate capsular and labral management. However, in severe hip dysplasia, with LCEA below 18°, there is an acetabular bony structural deficiency that must be addressed. Even with the potential benefit of hip arthroscopy in addressing intra-articular injuries related to the instability, it cannot be used for soft-tissue procedures. Periacetabular osteotomy remains the gold standard to address that matter; however, its invasive nature along with the long recovery time leaves some patients unwilling to undergo this procedure. New minimally invasive endoscopic procedures, derived from open techniques, describe acetabular autologous bone grafting as an alternative. Donor-side morbidity is always a concern when using autografts; we believe that the use of bone allograft will decrease this potential issue and make the procedure itself less invasive. This Technical Note will describe a type of endoscopic shelf acetabuloplasty using an allograft iliac bone graft.

Does Iliopsoas Lengthening Adversely Affect Clinical Outcomes After Hip Arthroscopy? A Multicenter Comparative Study.

BACKGROUND: Iliopsoas fractional lengthening (IFL) continues to be a controversial procedure in hip arthroscopy. HYPOTHESIS: Patients who underwent arthroscopic surgery for femoroacetabular impingement (FAI) and a labral tear either with or without IFL would experience favorable outcomes, and there would be no difference in postoperative patient-reported outcomes (PROs) between the 2 groups at minimum 2-year follow-up. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data from July 2009 and April 2015 were retrospectively reviewed. Patients were eligible if they had hip arthroscopy for both FAI and labral tear treatment with IFL and without IFL. IFL was indicated for painful internal snapping. Minimum postoperative follow-up was set to 2 years. The authors calculated the modified Harris Hip Score, International Hip Outcome Tool-12, Hip Outcome Score-Activity of Daily Living Score, Hip Outcome Score-Sports Specific Subscale, Non-Arthritic Hip Score, visual analog scale for pain, patient satisfaction, minimal clinically important difference (MCID), and the percentage of patients who achieved patient acceptable symptomatic state (PASS). Revision surgeries and conversions to total hip arthroplasty (THA) were documented. RESULTS: 351 hips (307 patients) met the necessary inclusion criteria in the IFL cohort, with a mean ± SD follow-up time of 42.5 ± 18.1 months. For the control cohort, 392 hips (354 patients) were included, with a mean ± SD follow-up time of 43.9 ± 19.6 months. Both groups showed significant postoperative improvement in 2-year follow-up PROs. The group with iliopsoas lengthening showed comparable results to the control group with respect to PRO improvement, MCID, PASS, and rates of revision or THA conversion. CONCLUSION: This comparative cohort study demonstrated that treatment of painful internal snapping syndrome with arthroscopic IFL, in the setting of FAI and a labral tear, is a safe procedure with good short- to mid-term follow-up results and associated improvement in PROs. Patients who underwent IFL showed similar outcomes compared with a control group treated for FAI and labral tear without IFL. In appropriately selected patients, arthroscopic IFL did not adversely affect clinical outcomes compared with patients who did not need IFL.

Return to Play Among Golfers Undergoing Hip Arthroscopy: Short- to Mid-term Follow-up.

There are approximately 25 million amateur golfers in the United States, making up almost 10% of the entire US population. The purpose of this study was to evaluate short-term outcomes and rates of return to sport among recreational golfers who underwent hip arthroscopy for the treatment of labral tears. Data were prospectively collected and retrospectively reviewed for patients who underwent hip arthroscopy by one surgeon between August 2008 and February 2015. Exclusion criteria were previous ipsilateral hip surgeries or conditions, preoperative Tönnis osteoarthritis grade greater than 1, or workers' compensation status. Patients who played golf at a recreational level within 1 year prior to their surgery, attempted to return to golf postoperatively, and had preoperative and minimum 2-year postoperative measures for the modified Harris hip score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale for pain were included in the final cohort. Data on return to sport, surgical complications, and secondary surgeries were recorded. Of the 49 patients eligible for inclusion, 40 (81.6%) had minimum 2-year follow-up at a mean of 51.0 months. Mean age at surgery was 49.1 years. All patient-reported outcomes and visual analog scale scores were significantly improved at latest follow-up. Thirty-six (90%) of the 40 patients returned to golf after surgery. Hip arthroscopy leads to significant improvement in patient-reported outcomes and a high rate of return to sport for recreational golfers presenting with labral tears. Therefore, it is a good treatment option for this patient population. [Orthopedics. 2018; 41(4):e545-e549.].

Arthroscopic Iliopsoas Fractional Lengthening.

BACKGROUND: Iliopsoas fractional lengthening (IFL) is performed on patients with symptomatic internal snapping. This condition is defined as painful and sometimes audible snapping of the iliopsoas (IP) tendon over the femoral head or iliopectineal line. Arthroscopic IFL is performed if the snapping is unresponsive to conservative treatment1,2. DESCRIPTION: Hip arthroscopy is performed with the patient in the supine position on a traction table. The portals used to access the joint capsule include standard anterolateral, mid-anterior, and distal anterolateral accessory (DALA) portals3. With a 70° arthroscope, diagnostic arthroscopy is conducted to assess the quality of labral tissue, acetabular and femoral cartilage surfaces, and the ligamentum teres. When indicated, supplementary procedures, such as acetabuloplasty, labral repair, or labral reconstruction4, are performed prior to IFL. With traction still applied, IFL is then performed from the central compartment at the level of the joint line. Exposure of the IP tendon is achieved with the use of a curved blade to extend the capsulotomy medially over the 3 o'clock position (right hip). Once the tendon can be appropriately visualized, a progressive and complete transverse cut is made in the tendinous portion, taking care to avoid the muscular portion. During this process, the anterolateral and mid-anterior portals serve as visualization and working portals, respectively5. ALTERNATIVES: Prior to arthroscopic IFL for painful internal snapping, nonsurgical options6,7 may include (1) physical therapy programs, (2) activity modification, (3) nonsteroidal anti-inflammatory drugs (NSAIDs), or (4) ultrasound-guided cortisone injections.
