RESUMO
BACKGROUND: Complete atrioventricular septal defect (CAVSD) in association with tetralogy of Fallot is a rare and complex disease that makes its repair more difficult than repair of either lesion alone. We reviewed retrospectively our experience in managing this lesion. PATIENTS AND METHODS: Between February 2006 and May 2017, 16 patients who underwent repair of CAVSD/tetralogy of Fallot (TOF) were reviewed retrospectively. Fifteen patients had trisomy 21. Five patients underwent primary repair while eleven patients went for staged repair in the form of right ventricular outflow tract (RVOT) stenting (n = 9) or systemic to pulmonary (S-P) surgical shunt (n = 2). RVOT stenting has replaced surgical shunt since 2012 in our center. Early presentation with cyanosis was the main determinant factor for staged versus primary repair. RESULTS: The median age at first palliation was 46 days (range 15-99 days). The median age at total repair for both groups was 6 months (range 3-18 months); the median age for the palliated patients was 6.5 months (range 5-18 months) while the median age for primary repaired patients was 5 months (range 3-11 months). The median weight at final repair was 6.9 kg (3.7-8.2 kg). The pulmonary valve was preserved in five patients (31%), four of them had no prior palliation. Chylothorax occurred in 50% of the patients. One late mortality occurred after final repair due to sepsis. CONCLUSION: CAVSD/TOF can be repaired with low mortality and morbidity. The use of RVOT stent has replaced the surgical (S-P) shunt with acceptable results in our center.
RESUMO
OBJECTIVES: Our unit has pursued Fontan completion in all patients except those with immobility or combined poor ventricular function and high pulmonary artery pressures. We assessed retrospectively whether conventional high-risk criteria would predict patients with a poorer outcome. METHODS: One hundred and thirty-three consecutive children who underwent extracardiac Fontan completion (2004-2012) had their outcomes recorded (mean follow-up of 7 years). Three groups were analysed: those with 1 of 6 historical risk factors (outside 6 commandments), those with 1 of reduced systemic ventricular function or pulmonary artery pressure >15 mmHg (outside 2 commandments) versus those with no contraindications. The Fischer's exact test examined frequency differences, with the χ2 test to look for outcome associations. RESULTS: There were no differences in postoperative complication rates between the outside 6 commandments (n = 105) or outside 2 commandments (n = 49) versus the low-risk no-contraindication group (n = 28): arrhythmias [18% (P = 0.3) or 18% (P = 0.3) vs 25%], infection [22% (P = 0.6) or 33% (P = 0.2) vs 21%], cerebrovascular accident [6% (P = 0.5) or 10% (P = 0.3) vs 4%], length of stay [20 days (P = 0.4) or 23 days (P = 0.2) vs 21 days] and duration of chest drainage (P = 0.5). There was 1 predischarge mortality in each group. Long term, the majority of patients in each group had suitable haemodynamics for fenestration closure [95% (P = 0.7) or 95% (P = 0.7) vs 92%]. Long term, there was no difference in the rate of arrhythmias [11% (P = 0.5) or 12.5% (P = 0.3) vs 7%], protein-losing enteropathy [1% (P = 0.1) or 2% (P = 0.3) vs 7%] or moderate or more ventricular dysfunction on echocardiography [2% (P = 0.7) or 4% (P = 0.7) vs 4%]. Notably, there was a higher rate of catheter reinterventions in the high-risk groups [22% (P < 0.05) or 24% (P < 0.05) vs 7%]. CONCLUSIONS: The medium-term benefits of Fontan completion can be achieved for high-risk patients, suggesting that historical selection criteria should be re-examined.

The purpose of this study was to determine if patients undergoing hip arthroscopy for labral pathology with contralateral total hip arthroplasty (THA) have a difference in revision surgeries or patient-reported outcomes (PROs) when compared with those patients undergoing hip arthroscopy for labral pathology with a native contralateral hip. A retrospective review was performed for patients that were undergoing hip arthroscopy between 2008 and 2015. Patients were included in the study group if they met the following inclusion criteria: Tönnis Grade 0 or 1, hip labral pathology, previous contralateral THA, and greater than 2-year follow-up with completion of all PROs or conversion to a THA. Exclusion criteria included the previous surgical history on ipsilateral hip, peritrochanteric or deep gluteal space arthroscopy performed concomitantly, or dysplasia [Lateral Center Edge Angle (LCEA) < 20°]. A 3:1 matched-pair study was conducted. Multiple PRO scores were recorded for both groups. There was no statistically significant difference in the modified Harris hip score, non-arthritic hip score, hip outcome score-sports specific sub-scale, visual analog pain score and patient satisfaction scores between both groups. However, the study group was noted to have six patients converted to THA (67%) at an average of 30 months post-operatively, compared with only four patients (15%) in the control group (P = 0.006). Hip arthroscopy cannot be currently recommended in patients who have undergone contralateral THA due to the high conversion to THA (67%).
RESUMO
BACKGROUND: The technique of hip arthroscopic surgery is advancing and becoming more commonly performed. However, most current reported results are limited to short-term follow-up, and therefore, the durability of the procedure is largely unknown. PURPOSE: To perform a multicenter analysis of mid-term clinical outcomes of arthroscopic hip labral repair and determine the risk factors for patient outcomes. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Prospectively collected data of primary hip arthroscopic labral repair performed at 4 high-volume centers between 2008 and 2011 were reviewed retrospectively. Patients were assessed preoperatively and postoperatively with the visual analog scale (VAS), modified Harris Hip Score (mHHS), and Hip Outcome Score-Sports-Specific Subscale (HOS-SSS) at a minimum of 5 years' follow-up. Factors including age, body mass index (BMI), Tönnis grade, and cartilage grade were analyzed in relation to outcome scores, and revision rates were determined. Failure was defined as subsequent ipsilateral hip surgery, including revision arthroscopic surgery and open hip surgery. RESULTS: A total of 303 patients (101 male, 202 female) with a mean age of 32.0 years (range, 10.7-58.9 years) were followed for a mean of 5.7 years (range, 5.0-7.9 years). Patients achieved mean improvements in VAS of 3.5 points, mHHS of 20.1 points, and HOS-SSS of 29.3 points. Thirty-seven patients (12.2%) underwent revision arthroscopic surgery, and 12 (4.0%) underwent periacetabular osteotomy, resurfacing, or total hip arthroplasty during the study period. Patients with a BMI >30 kg/m2 had a mean mHHS score 9.5 points lower and a mean HOS-SSS score 15.9 points lower than those with a BMI ≤30 kg/m2 ( P < .01). Patients aged >35 years at surgery had a mean mHHS score 4.5 points lower and a HOS-SSS score 6.7 points lower than those aged ≤35 years ( P = .03). Patients with Tönnis grade 2 radiographs demonstrated a 12.5-point worse mHHS score ( P = .02) and a 23.0-point worse HOS-SSS score ( P < .01) when compared with patients with Tönnis grade 0. CONCLUSION: Patients demonstrated significant improvements in VAS, mHHS, and HOS-SSS scores after arthroscopic labral repair. However, those with Tönnis grade 2 changes preoperatively, BMI >30 kg/m2, and age >35 years at the time of surgery demonstrated significantly decreased mHHS and HOS-SSS scores at final follow-up.

BACKGROUND: Failure of hip preservation to alleviate symptoms potentially subjects the patient to reoperation or conversion surgery to THA, adding recovery time, risk, and cost. A risk calculator using an algorithm that can predict the likelihood that a patient who undergoes arthroscopic hip surgery will undergo THA within 2 years would be helpful, but to our knowledge, no such tool exists. QUESTIONS: (1) Are there preoperative and intraoperative variables at the time of hip arthroscopy associated with subsequent conversion to THA? (2) Can these variables be used to develop a predictive tool for conversion to THA? MATERIALS AND METHODS: All patients undergoing arthroscopy from January 2009 through December 2011 were registered in our longitudinal database. Inclusion criteria for the study group were patients undergoing hip arthroscopy for a labral tear, who eventually had conversion surgery to THA. Patients were compared with a control group of patients who underwent hip arthroscopy for a labral tear but who did not undergo conversion surgery to THA during the same study period. Of the 893 who underwent surgery during that time, 792 (88.7%) were available for followup at a minimum of 2 years (mean, 31.1 ± 8.1 years) and so were considered in this analysis. Multivariate regression analyses of 41 preoperative and intraoperative variables were performed. Using the results of the multivariate regression, we developed a simplified calculator that may be helpful in counseling a patient regarding the risk of conversion to THA after hip arthroscopy. RESULTS: Variables simultaneously associated with conversion to THA in this model were older age (rate ratio, 1.06; 95% CI, 1.03-1.08; p < 0.0001), lower preoperative modified Harris hip score (rate ratio [RR], 0.98; 95% CI, 0.96-0.99; p = 0.0003), decreased femoral anteversion (RR, 0.97; 95% CI, 0.94-0.99; p = 0.0111), revision surgery (RR, 2.4; 95% CI, 1.15-5.01; p = 0.0193), femoral Outerbridge Grades II to IV (Grade II: RR, 2.23 [95% CI, 1.11-4.46], p = 0.023; Grade III: RR, 2.17, [95% CI, 1.11-4.23], p = 0.024; Grade IV: RR, 2.96 [95% CI, 1.34-6.52], p = 0.007), performance of acetabuloplasty (RR, 1.83; 95% CI, 1.03-3.24; p = 0.038), and lack of performance of femoral osteoplasty (RR, 0.62; 95% CI, 0.36-1.06; p = 0.081). Using the results of the multivariate regression, we developed a simplified calculator that may be helpful in counseling a patient regarding the risk of conversion surgery to THA after hip arthroscopy. CONCLUSION: Multiple risk factors have been identified as possible risk factors for conversion to THA after hip arthroscopy. A weighted calculator based on our data is presented here and may be useful for predicting failure after hip arthroscopy for labral treatment. Determining the best candidates for hip preservation remains challenging; careful attention to long-term followup and identifying characteristics associated with successful outcomes should be the focus of further study. LEVEL OF EVIDENCE: Level III, therapeutic study.

This study reviewed pain and outcome scores of patients undergoing revision surgery with heterotopic ossification (HO) excision following previous hip arthroscopy. The aim was to determine if performing the excision arthroscopically improved clinical outcomes. Data were prospectively collected and retrospectively reviewed in patients who had HO removed arthroscopically between February 2008 and 2014. Four patient-reported outcome (PRO) measures were collected: Modified Harris Hip Score (mHHS), Non-Arthritis Hip Score (NAHS), Hip Outcome Score-Activity of Daily Living (HOS-ADL) and Sport-Specific (HOS-SS) subscales. Minimum 1.5 year follow-up from index procedure was available for 23 patients (mean age = 38.6 years). Of the 23 patients who had revision surgery and HO removal, 19 (83%) were available for follow-up. Prior to revision, the average mHHS was 53.4, HOS-ADL 51.4, HOS-SS 24.5, NAHS 50.3 and VAS 6.7. Following revision with HO excision, each score had improved with an average mHHS of 73.62, HOS-ADL of 68.88, HOS SS of 58.51, NAHS of 70.83 and VAS of 4.33. Overall, mHHS increased by 20.26 points (P < 0.001), HOS-ADL increased by 17.48 points (P = 0.023), HOS-SS increased by 34.03 points (P < 0.001), NAHS increased by 20.55 points (P = 0.001) and VAS decreased by 2.38 points (P < 0.001). Patients undergoing revision hip surgery with HO excision demonstrated improved outcome scores and pain resolution; however, few patients achieved a good or excellent result. Revision hip surgery with HO excision should be approached cautiously because of the modest results in this patient group.
RESUMO
PURPOSE: To examine arthroscopic treatment of hip pain in patients with borderline hip dysplasia (lateral center edge angle [LCEA] between 20° and 25°). METHODS: From 2008 to 2013, patients below 18 years of age who underwent arthroscopic hip surgery with an LCEA between 20° and 25° were retrospectively matched 1:1 to a control group without dysplasia (LCEA ≥25°) based on age, gender, femoroplasty, labral treatment, and capsular plication. Indications for surgery included failure to improve with nonoperative treatments and anti-inflammatory medications after 3 months. Patient-reported outcome data were collected using modified Harris hip score, hip outcome score-activities of daily living subscale, hip outcome score-sports-specific subscale, nonarthritic athletic hip score, and visual analog scale. RESULTS: From 2008 to 2013, 168 patients below the age of 18 underwent arthroscopic hip surgery. Twenty-one patients met inclusion criteria and were matched 1:1 to a control group. Follow-up was achieved for 17 patients in both groups (81%). Mean follow-up time, age, and LCEA were 2.19 years, 15.5 years, and 22.3° for the dysplastic group and 2.16 years, 16.0 years, and 31.2° for the control group, respectively. Preoperative patient-reported outcomes between groups were not statistically different. At the latest follow-up, both groups showed statistically significant improvement over baseline in modified Harris hip score, hip outcome score-activities of daily living subscale, hip outcome score-sports-specific subscale, nonarthritic athletic hip score, and visual analog scale (P < .001). Latest follow-up scores were not statistically different between groups. CONCLUSIONS: This study shows favorable 2-year outcomes in adolescent patients with borderline dysplasia undergoing labral treatment and capsular plication. Outcomes in the borderline dysplastic patients were as good as those of a control group. Although adolescents with borderline dysplasia have traditionally been a challenging group of patients to treat, these results suggest that an arthroscopic approach that addresses both labral pathology and instability may be beneficial. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

In recent years, three-dimensional printing has demonstrated reliable reproducibility of several organs including hearts with complex congenital cardiac anomalies. This represents the next step in advanced image processing and can be used to plan surgical repair. In this study, we describe three children with complex univentricular hearts and abnormal systemic or pulmonary venous drainage, in whom three-dimensional printed models based on CT data assisted with preoperative planning. For two children, after group discussion and examination of the models, a decision was made not to proceed with surgery. We extend the current clinical experience with three-dimensional printed modelling and discuss the benefits of such models in the setting of managing complex surgical problems in children with univentricular circulation and abnormal systemic or pulmonary venous drainage.

PURPOSE: Patient-reported outcome (PRO) scores are used to evaluate treatment modalities in orthopaedic surgery. The method of PRO collection may introduce bias to reported surgical outcomes due to the presence of an interviewer. This study evaluates post-operative PROs for variation of outcomes between survey methods-in-person, online, or telephone. METHODS: From 2008 to 2011, 456 patients underwent arthroscopic surgical treatment for acetabular labral tears. All pre-operative surveys were completed in the clinic during pre-operative visit. Two-year follow-up questionnaires were completed by 385 (84 %) patients. The PRO data were prospectively collected pre- and post-operatively using five tools: modified Harris Hip Score (mHHS), Hip Outcome Score Activities of Daily Living (HOS-ADLS), Hip Outcome Score Sports-Specific Subscale (HOS-SSS), Non-Arthritic Hip Score (NAHS), and visual analog scale. Patients were grouped according to method of 2-year follow-up: in-person during follow-up visit (102 patients, 26 %), online by email prompt (138 patients, 36 %), or telephone with an interviewer (145 patients, 38 %). RESULTS: Pre-operative baseline PRO scores demonstrated no statistically significant difference between groups for mHHS, HOS-ADLS, HOS-SSS, and NAHS. Two-year post-operative PRO scores obtained by telephone were statistically greater than scores obtained in-person or online for mHHS (p < 0.001), HOS-ADLS (p < 0.001), and HOS-SSS (p < 0.01). CONCLUSION: This study demonstrates higher patient-reported outcome scores and greater improvement by telephone surveys compared to in-person or online. The variation of results between collection methods is indicative of a confounding variable. Clinically, it is important to understand these confounding variables in order to assess patient responses and guide treatment. LEVEL OF EVIDENCE: IV.

Previous studies assessed elite athletes' return to sport (RTS) after hip arthroscopy, but few investigated a cohort including athletes from all levels of sport. This study compared athletes who returned to sport to those who did not, based on four patient-reported outcome (PRO) scores, including the Hip Outcome Score-Sports Specific Subscale (HOS-SSS). Between September 2008 and April 2012, hip arthroscopies were performed on 157 patients (168 hips) who reported playing a sport preoperatively and indicated their level of sports activity post-operatively. Two-year follow-up was available for 148 (94%) amateur and professional athletes with a total of 158 hips. Of these 60 cases (65 hips) did not return to sports (NRTS) and were in the NRTS group. The remaining 88 cases (93 hips) constituted the RTS group. The modified Harris Hip Score, Non-Arthric Hip Score, Hip Outcome-Activities of Daily Living (HOS-ADL), and HOS-SSS were used to assess outcomes. The HOS-SSS was used to assess specific sport-related movement. Both groups demonstrated significant improvement at 2 years post-operatively in visual analog score and four PRO scores (P < 0.001). There was no significant preoperative differences in HOS-SSS scores between groups; however, the RTS group had significantly higher HOS-SSS scores at 1 and 2 years post-surgery. Post-operatively, the RTS group had significantly better ability to jump, land from a jump, stop quickly and perform cutting/lateral movements (P < 0.05). In summary, patients who indicated RTSs demonstrated significantly higher PRO scores and abilities to perform several sport-related movements, compared with patients who did not.
RESUMO
The treatment of chondral hip injuries is challenging. However, for young patients with hip disorders, orthopedic surgeons now have the opportunity to intervene early in the development of debilitating joint disease. As understanding of the hip joint continues to evolve, more effective treatment strategies are emerging. There are several reportedly successful options for surgical treatment. This article reviews the clinical presentation of chondral injuries and the surgical modalities, arthroscopic and open, available to treat them.

Robotic-assisted total hip arthroplasty (THA) is a recent platform introduced to decrease the risk of malpositioned components. The goals of this study were to determine whether intraoperative data on robotic-assisted THA acetabular component position accurately predict postoperative radiographic acetabular component position and to determine whether intraoperative data on robotic-assisted THA leg length and offset accurately predict postoperative radiographic leg length and offset data. In 146 patients, pre- and postoperative radiographs and intraoperative component measurements were reported for acetabular inclination, anteversion, leg length change, and offset change. Component position obtained by the robotic system and radiographic data were compared with subgroup analysis for the posterior and direct anterior approaches. The average difference between groups was 3.3°±3.1° for inclination, 2.9°±2.3° for anteversion, 3.0±2.3 mm for leg length change, and 4.0±3.1 mm for change in global offset. Correlation between the robotic system and postoperative radiographs was within 10° for 95.9% of cases for inclination and 99.3% for anteversion. Posterior approach correlation was within 10° for 97.1% of cases for inclination and 100% for anteversion. Anterior approach correlation was within 10° for 92.7% of cases for inclination and 97.6% for anteversion. Intraoperative data on component position obtained from the robotic system compared well with radiographic data on component position. Surgeons must remain vigilant to ensure outliers related to robotic system malfunction do not occur. [Orthopedics. 2016; 39(3):193-199.].

Patients who have lateral hip pain historically have been diagnosed with trochanteric bursitis and treated with nonsteroidal anti-inflammatory medications, corticosteroid injections, and physical therapy. Although this strategy is effective for most patients, a substantial number of patients continue to have pain and functional limitations. Over the past decade, our understanding of disorders occurring in the peritrochanteric space has increased dramatically. Greater trochanteric pain syndrome encompasses trochanteric bursitis, external coxa saltans (ie, snapping hip), and abductor tendinopathy. A thorough understanding of the anatomy, examination findings, and imaging characteristics aids the clinician in treating these patients. Open and endoscopic treatment options are available for use when nonsurgical treatment is unsuccessful.

PURPOSE: To evaluate clinical outcomes, pain, and patient satisfaction following revision hip arthroscopy with a minimum 2-year follow-up. METHODS: From April 2008 to October 2011, data were prospectively collected on all patients undergoing revision hip arthroscopy. All patients were assessed pre- and postoperatively with 4 patient-reported outcome (PRO) measures: the modified Harris hip score (mHHS), nonarthritic hip score (NAHS), hip outcome score-activities of daily living (HOS-ADL), and hip outcome score-sport-specific subscales (HOS-SSS). Pain was estimated on the visual analog scale (VAS). Patient satisfaction was measured on a scale from 0 to 10. The number of patients who underwent subsequent revision arthroscopy or total hip arthroplasty during the study period is also reported. RESULTS: Eighty-seven patients underwent revision hip arthroscopy during the study period. Seventy (80.5%) patients were included in our study. Average follow-up time was 28 months (range, 20 to 47.4 months). In terms of residual femoroacetabular impingement morphology, 45.7% of patients had preoperative alpha angles ≥ 55°, and 7.14% of patients had a lateral center-edge angle ≥ 40°. The score improvement from preoperative to 2-year follow-up was 57.84 to 73.65 for mHHS, 62.79 to 83.04 for HOS-ADL, 37.33 to 54.93 for HOS-SSS, and 55.65 to 70.79 for NAHS. VAS decreased from 6.72 to 4.08. All scores demonstrated statistically significant improvement (P < .001). Overall patient satisfaction was 7.67. Our success rate was 74.58%. Ten (14.29%) patients underwent total hip arthroplasty during the study period. Our hip survivorship was 85.7%. Five (7.14%) patients underwent secondary revision hip arthroscopy during the study period. We found an overall minor complication rate of 10%. CONCLUSIONS: Revision hip arthroscopy for all procedures performed on aggregate has improved clinical outcomes for all PROs, high survivorship, and high patient satisfaction scores at short-term follow-up. Patients should be counseled regarding the potential progression of degenerative change leading to arthroplasty and the potential for revision surgery. LEVEL OF EVIDENCE: Level IV retrospective case series.

BACKGROUND: Hip arthroscopy has gained increasing popularity over the past decade. The need to develop metrics to evaluate success and complications in primary hip arthroscopy is an important goal. PURPOSE: To evaluate 2-year patient-related outcome (PRO) scores and patient satisfaction scores for a single surgeon at a high-volume referral center for all primary hip arthroscopy procedures performed. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: During the study period between April 2008 and October 2011, data were collected on all patients who underwent primary hip arthroscopy. All patients were assessed pre- and postoperatively with 4 PRO measures: the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), and Hip Outcome Score-Sport-Specific Subscale (HOS-SSS). Pain was estimated on the visual analog scale (VAS), and satisfaction was measured on a scale from 0 to 10. The number of patients who underwent revision arthroscopy, total hip arthroplasty (THA), or a resurfacing procedure during the study period was also reported. RESULTS: A total of 595 patients were included in the study. The score improvement from preoperative to 2-year follow-up was 61.29 to 82.02 for mHHS, 62.79 to 83.05 for HOS-ADL, 40.96 to 70.07 for HOS-SSS, 57.97 to 80.41 for NAHS, and 5.86 to 2.97 for VAS. All scores were statistically significantly different (P < .0001). Overall patient satisfaction was 7.86 ± 2.3 (range, 1-10). Forty-seven (7.7%) patients underwent revision hip arthroscopy, and 54 (9.1%) patients underwent either THA or the hip resurfacing procedure during the study period. The multivariate regression analysis showed that increased age at time of surgery was a significant risk factor for conversion to THA, revision arthroscopy, and change in NAHS <10 points. Acute injury, acetabuloplasty, iliopsoas release, and patient sex were significant for 2 of these 3 types of failure. CONCLUSION: Primary hip arthroscopy for all procedures performed in aggregate had excellent clinical outcomes and patient satisfaction scores at short-term follow-up in this study. More studies must be conducted to determine the definition of a successful outcome. There was a 6.1% minor complication rate, which was consistent with previous studies. Patients should be counseled regarding the potential progression of degenerative change leading to arthroplasty as well as the potential for revision surgery.

BACKGROUND: Hip dysplasia has been shown to be a cause of early arthritis. The decrease in bony coverage has shown increased stress on the acetabular labrum as it shares an increased load. PURPOSE/HYPOTHESIS: The purpose of this study was to divide a cohort of patients by radiographic measures of dysplastic and nondysplastic hips for comparison with regard to labral size at 4 anatomic locations. The hypothesis was that dysplastic hips will have significantly larger labral size compared with nondysplastic hips. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A prospective study was conducted at a single institution. A total of 130 patients underwent hip arthroscopy during the study period from September 2011 to February 2012. Intraoperatively, arthroscopic measurements were taken at 4 quadrants on the acetabular clockface: anterosuperior (12-3 o'clock), anteroinferior (3-6 o'clock), posterosuperior (9-12 o'clock), and posteroinferior (6-9 o'clock). Three radiographic parameters for dysplasia were used to substratify the study population base: lateral center-edge angle (LCEA) ≤25° and LCEA >25°, acetabular inclination (AI) ≤10° and AI >10°, and anterior center-edge angle (ACEA) ≤20° and ACEA >20°. RESULTS: For the LCEA ≤25° group, there were 28 hips with mean LCEA of 20.96° ± 3.40°. Patients with LCEA ≤25° had larger labral width in all 4 quadrants (P < .05). For AI >10°, there were 12 hips with the mean AI 12.92° ± 2.50°. Patients with AI >10° had larger labral size in the posteroinferior quadrant only (P < .05). For ACEA ≤20°, there were 4 hips with a mean ACEA of 11.25° ± 5.19°. The anteroinferior and posteroinferior quadrants had a significant increase in labral size when substratified by ACEA ≤20° (P < .05). CONCLUSION: Labral size was significantly larger in dysplastic hips compared with nondysplastic hips. The posteroinferior quadrant labrum was larger in size in dysplastic hips, as measured by any of the 3 radiographic measurements of dysplasia. Hips with LCEA ≤25° had larger labra in all 4 quadrants.
RESUMO
The purpose of this multi-surgeon study was to assess and compare the accuracy of acetabular component placement, leg length discrepancy (LLD), and global offset difference (GOD) between six different surgical techniques and modes of guidance in total hip arthroplasty (THA). A total of 1980 THAs met inclusion criteria. Robotic- and navigation-guided techniques were more consistent than other techniques in placing the acetabular cup into Lewinnek's safe zone (P<0.005 and P<0.05, respectively). Robotic-guided surgery was more consistent than other techniques in placing the acetabular component within Callanan's safe zone (P<0.005). No statistically significant differences were found between groups in the frequency of patients with excessive LLD. Clinically significant differences between groups were not found in the frequency of patients with excessive GOD. Level of Evidence: IV.

PURPOSE: To detail our early experience using concomitant hip arthroscopy and periacetabular osteotomy (PAO) for the treatment of acetabular dysplasia. METHODS: We prospectively collected and retrospectively reviewed the surgical and outcome data of 17 patients who underwent concomitant hip arthroscopy and PAO between October 2010 and July 2013. Preoperative and postoperative range of motion, outcome and pain scores, and radiographic data were collected. Intraoperative arthroscopic findings and postoperative complications were recorded. RESULTS: The group consisted of 3 male and 14 female patients with a mean follow-up period of 2.4 years. Three patients had undergone previous surgery on the affected hip. Chondrolabral pathology was identified in all 17 patients. Twelve patients underwent labral repair, and five patients underwent partial labral debridement. No patient was converted to total hip arthroplasty or required revision surgery at short-term follow-up. All 4 patient-reported outcome scores showed statistically significant changes from baseline to latest follow-up (P < .001). An excellent outcome was obtained in 82% of patients (13 of 16). The lateral center-edge angle averaged 11° preoperatively and 29° postoperatively. The acetabular inclination averaged 18° preoperatively and 3° postoperatively. The anterior center-edge angle averaged 7° preoperatively and 27° postoperatively. At most recent radiographic follow-up, 1 patient had progression of arthritic changes but remained asymptomatic. No other patient showed any radiographic evidence of progression of arthritis. Complications included 3 superficial wound infections, 1 pulmonary embolism, and 1 temporary sciatic neurapraxia. CONCLUSIONS: Our initial experience with concomitant hip arthroscopy and PAO has been favorable. We noted that all our patients have evidence of chondrolabral damage at the time of PAO when the joint is distracted and evaluated. All patients in this series had intra-articular pathology treated arthroscopically and showed satisfactory mean clinical improvement. Hip arthroscopy with PAO did not appear to introduce complications beyond the PAO alone. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Obese populations present challenges for acetabular cup placement during total hip arthroplasty (THA). This study examines the accuracy of acetabular cup inclination and version in the obese patient with robotic-assisted computer navigation. A total of 105 patients underwent robotic-assisted computer navigation THA with a posterior approach. Groups were divided on body mass index (BMI, kg/m(2)) of <30, 30-35, and >35. There was no statistical difference between the BMI <30 (n=59), BMI 30-35 (n=34) and BMI >35 (n=12) groups for acetabular inclination (P=0.43) or version (P=0.95). Robotic-assisted computer navigation provided accurate and reproducible placement of the acetabular cup within safe zones for inclination and version in the obese patient.

Recalcitrant osteitis pubis presents a challenging problem for orthopaedic surgeons. Various surgical interventions have been described for treatment, including opening-wedge resection, symphysiodesis, and curettage. We propose that endoscopic pubic symphysectomy offers an effective method of treating such a challenging problem. This article describes in detail the technique used to perform endoscopic pubic symphysectomy, and a companion video demonstrating the procedure is included. Our experience suggests that removal of the interpubic fibrocartilaginous lamina and resection of approximately 1 cm of bone can successfully eliminate all sources of pain and dysfunction caused by the recalcitrant osteitis pubis.
