Background: Recent evidence has demonstrated a high rate of return to running after hip arthroscopy for femoroacetabular impingement at short-term follow-up. The midterm outcomes and rates of continued running of these patients are unknown. Purpose: To evaluate midterm rates of return to running and outcomes after hip arthroscopy. Study Design: Case series; Level of evidence, 4. Methods: Data were prospectively collected for patients who underwent hip preservation surgery between July 2008 and November 2011. Patients were excluded for preoperative Tönnis osteoarthritis grade ≥2, previous ipsilateral hip conditions or hip surgery, or workers’ compensation status. All patients who participated in mid- to long-distance running before their surgery and intended on returning after their operation were considered for inclusion. Preoperative and minimum 5-year postoperative measures for the following patient-reported outcome scores (PROs) were necessary for inclusion in the final cohort: the modified Harris Hip Score, Non-arthritic Hip Score, Hip Outcome Score–Sports Specific Subscale, and visual analog scale (VAS) for pain. All patients were counseled about the risks of continued running after hip arthroscopy. Results: Sixty patients (62 hips) were eligible for inclusion, of which 50 (83.3%; 52 hips) had minimum 5-year follow-up. There were 10 male hips and 42 female hips. Mean ± SD age at surgery was 32.4 ± 12.4 years (range, 14.9-62.4), and mean body mass index was 22.9 ± 3.2 (range, 17.7-30.1). Latest follow-up was recorded at a mean 69.3 ± 8.5 months (range, 60.0-92.1 months). Level of competition included 39 recreational, 7 high school, 4 collegiate, and 2 professional athletes. There were significant improvements in all PROs and VAS scores preoperatively to latest follow-up. Mean modified Harris Hip Score improved from 67.5 to 88.2; mean Non-arthritic Hip Score, from 65.9 to 88.3; mean Hip Outcome Score–Sports Specific Subscale, from 49.5 to 81.0; and mean VAS, from 5.2 to 1.5. At latest follow-up, patient satisfaction was 8.4. Thirty-nine patients (78.0%, 41 hips) had returned to running postoperatively. When stratified by level of competition, 79% (31 of 39) of recreational, 100% (7 of 7) of high school, 50% (2 of 4) of collegiate, and 50% (1 of 2) of professional athletes returned to running. Conclusion: Hip arthroscopy for all levels of runners is associated with a significant increase in PROs and a low risk of complications. The rate of return to running is moderately high after hip arthroscopy at midterm follow-up. Hip arthroscopy may be considered for runners presenting with symptoms of femoroacetabular impingement that fail nonoperative treatments. Patients should be educated on the rate of return to running over time and the risks of continued running after hip arthroscopy.

Background: The influence of femoral torsion on clinically significant outcome improvement after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) has not been well-studied. Purpose: To quantify femoral torsion in FAIS patients using magnetic resonance imaging (MRI) and explore the relationship between femoral torsion and clinically significant outcome improvement after hip arthroscopy. Study Design: Cohort study; Level of evidence, 3. Methods: Included were patients who underwent hip arthroscopy for FAIS between January 2012 and August 2018 and had 2-year follow-up and preoperative MRI scans containing transcondylar slices of the knee. Participants were categorized as having severe retrotorsion (SR; <0°), normal torsion (NT; 0°-25°), and severe antetorsion (SA; >25°) as measured on MRI. Patient-reported outcomes (PROs) included the Hip Outcome Score–Activities of Daily Living, Hip Outcome Score–Sports Subscale, modified Harris Hip Score, 12-item International Hip Outcome Tool (iHOT-12), and visual analog scale (VAS) for pain and satisfaction. Achievement of Patient Acceptable Symptom State (PASS) and substantial clinical benefit (SCB) were analyzed among cohorts. Results: Included were 183 patients (SR, n = 13; NT, n = 154; SA, n = 16) with a mean age, body mass index, and femoral torsion of 30.6 ± 12.1 years, 24.0 ± 4.4 kg/m2, and 12.55° ± 9.58°, respectively. The mean torsion was –4.5° ± 2.6° for the SR, 12.1° ± 6.8° for the NT, and 31.0° ± 3.6° for the SA group. There were between-group differences in the proportion of patients who achieved PASS and SCB on the iHOT-12, pain VAS, and any PRO ( P < .05). Post hoc analysis indicated that the SA group achieved lower rates of PASS and SCB on the iHOT-12 and pain VAS, and lower rates of PASS on any PRO versus the SR group ( P < .05); the SR group achieved higher rates of PASS and SCB on pain VAS scores versus the NT group ( P = .003). Conclusion: The orientation and severity of femoral torsion during hip arthroscopy influenced the propensity for clinically significant outcome improvement. Specifically, patients with femoral retrotorsion and femoral antetorsion had higher and lower rates of clinically significant outcome improvement, respectively.

Background: There is a dearth of knowledge regarding the correlation between femoroacetabular impingement (FAI) and osteitis pubis (OP) among symptomatic soccer players. Purpose: To elucidate whether arthroscopic FAI correction is effective for young competitive soccer players with FAI combined with OP or perisymphyseal pubic bone marrow edema (BME). Study Design: Case series; Level of evidence, 4. Methods: A total of 577 consecutive patients who underwent arthroscopic FAI correction were retrospectively reviewed with a minimum 2-year follow-up. Competitive soccer players who were professional, college, and high school athletes were included. The authors assessed the modified Harris Hip Score and Nonarthritic Hip Score preoperatively and at 6 months, 1 year, and 2 years after surgery. In addition, players were divided into groups according to radiographic evidence of OP and BME (2 groups each). Clinical outcomes, return to play, and radiographic assessments were compared between groups. Results: Twenty-eight hips met the inclusion criteria. The median modified Harris Hip Score significantly improved after hip arthroscopy (81.4, preoperatively; 95.7 at 6 months, P = .0065; 100 at 1 year, P = .0098; 100 at 2 years, P = .013). The median Nonarthritic Hip Score also significantly improved (75.0, preoperatively; 96.3 at 6 months, P = .015; 98.8 at 1 year, P = .0029; 100 at 2 years, P = .015). Furthermore, 92.0% of players returned to play soccer at the same or higher level of competition at a median 5.5 months (range, 4-15 months); 67.8% had radiological confirmation of OP; and 35.7% had pubic BME. The alpha angle was significantly higher in pubic BME group than the no–pubic BME group (64.8° vs 59.2°, P = .027), although there was no significant difference between the OP and no-OP groups. The prevalence of tenderness of the pubic symphysis significantly decreased preoperatively (32.1%) to postoperatively (3.6%). Magnetic resonance imaging findings confirmed that pubic BME disappeared in all players at a median 11 months (range, 6-36) after initial surgery. Conclusions: Arthroscopic management for FAI provides favorable clinical outcomes, a high rate of return to sports, and, when present, resolution of pubic BME among competitive soccer players.

Purpose: To build a post-arthroscopy outcome-predictive score (POPS) associated with the likelihood of lasting benefit after arthroscopic treatment of femoroacetabular impingement (FAI) and based solely on unambiguous preoperative information. Methods: A population of 220 FAI patients, operated on with standard techniques by orthopaedic surgeons trained in hip arthroscopy in 6 different centres, was evaluated physically or by telephone interview 2 to 5 years after surgery. The criteria of successful mid-term outcome (SMO) were agreed upon by all authors. A multivariate logistic regression, adjusted for patient’s age and centre, was applied to predict SMO. In the model, the variables associated with the outcome were included and the relative ORs (odds ratios) were used to compute the FAI-POPS (FAI - post-arthroscopy outcome-predictive score). A ROC (receiver operating characteristic) curve was plotted and the optimum cut-off was calculated. Results: 155 patients out of 220 showed a successful mid-term outcome. The optimum cut-off of FAI-POPS was calculated to be 6.3 and with this threshold it proved a sensitivity of 0.66 and a specificity of 0.69, a positive predictive value of 0.84 and a negative predictive value of 0.46. Conclusions: The standard arthroscopic treatment of FAI resulted in satisfactory persistent symptom relief for about 70% of patients. No or minimal osteoarthritis, short time elapsed from the appearance of symptoms and high preoperative modified Harris Hip Score are independent predictive factors of SMO. The FAI-POPS is obtained as sum of 3 odds ratios corresponding to the above prognostic factors and is a useful predictor of mid-term outcome after conventional arthroscopic FAI treatment.

Background: The minimal clinically important difference (MCID) has been defined in orthopaedics and is the smallest change that a patient considers meaningful. Less is known about improvements that the patient perceives as clinically considerable, or the substantial clinical benefit (SCB). For the young, highly functioning patient cohort with femoroacetabular impingement (FAI), the SCB is an important measure of clinical success. Purpose: To derive the SCB for FAI treatment and identify outcome score thresholds and patient variables predictive of the SCB. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: The modified Harris Hip Score (mHHS), the Hip Outcome Score activities of daily living (HOS-ADL) and sport (HOS-Sport) subscales, and the international Hip Outcome Tool (iHOT-33) were prospectively administered to 364 patients with a minimum 1-year follow-up. At 1 year postoperatively, patients graded their hip function based on several anchor responses such as “no change” and “much improved.” The SCB was defined as the change on each outcome tool that equated to the difference between “no change” and “much improved” on the health transition question. Receiver operating characteristic analysis with area under the curve (AUC) was used to identify optimal values that were most representative of the SCB. Multivariable analysis identified patient variables predictive of the SCB. Results: The net change in outcome scores corresponding to the SCB for the mHHS, HOS-ADL, HOS-Sport, and iHOT-33 was 19.8, 10.0, 29.9, and 24.5, respectively. The following postoperative outcome scores demonstrated excellent distinction (AUC >0.8) between “no change” and “much improved” and thus were considered absolute values for the postoperative SCB: 82.5 (mHHS), 93.3 (HOS-ADL), 84.4 (HOS-Sport), and 63.5 (iHOT-33). Preoperative scores on the HOS-ADL (83.3) and HOS-Sport (50.0) were significant threshold cutoffs, above which attaining the SCB became less likely. Younger age and lower Outerbridge grade were predictive of achieving the SCB. Conclusion: The SCB has not been previously defined in the hip preservation literature and is complementary to the MCID as the upper bound for clinically significant improvement. We identified predictive preoperative and diagnostic postoperative outcome scores for the SCB that can be used to manage patient expectations and grade outcomes. These findings are objective criteria for defining clinical success after arthroscopic FAI treatment.

Background: Femoroacetabular impingement (FAI) is most commonly diagnosed in athletes who sustain repetitive flexion loading to their hips. No studies to date have focused solely on patients’ return-to-running ability after hip arthroscopy. Purpose: To evaluate patients’ ability to return to running after hip arthroscopy for FAI and capsular plication. Study Design: Case series; Level of evidence, 4. Methods: Clinical data were retrospectively retrieved for 51 consecutive patients with FAI (22 men, 29 women) who had undergone hip arthroscopy for the treatment of FAI and identified themselves as recreational or competitive runners on intake forms. Two-year outcome measures included the modified Harris Hip Score (mHHS) and the Hip Outcome Score Activities of Daily Living (HOS-ADL) and Sport-Specific (HOS-SS) subscales. A postoperative return-to-running survey was used to obtain running-specific information. Results: Patient age and body mass index (BMI) were a mean (±SD) of 26.3 ± 7.8 years and 23.7 ± 3.3 kg/m2, respectively. Before surgery, patients had refrained from running because of pain for a mean of 8.1 ± 5.7 months. After surgery, 48 patients (94%) returned to running at a mean of 8.5 ± 4.2 months. Patients who had discontinued running for more than 8 months before surgery had a longer return-to-running time than did those who had stopped for less than 8 months (10.6 ± 4.2 vs 7.6 ± 4.1 months; P = .01). After 2 years, mean preoperative distance had decreased significantly ( P < .01) from 9.5 ± 6.5 miles per week when healthy to 6.4 ± 5.8 miles postoperatively. Despite decreased mileage, all 2-year outcomes scores improved significantly ( P < .001). Conclusion: Recreational and competitive runners with FAI returned to running 94% of the time at a mean of 8.5 months after hip arthroscopy. However, runners should be counseled before their surgery that they may run fewer miles than when they were pain free. Additionally, patients with a higher BMI and/or longer preoperative lull may have a longer recovery time.

Mid Term Results

We describe one- to three-year results of a novel use of fibrin glue in the treatment of cartilage damage by arthroscopy in the hip. This technique uses the microfracture technique and fibrin adhesive to bond delaminated articular cartilage to the underlying subchondral bone. This is generally performed in conjunction with treatment of underlying pathology such as femoroacetabular impingement. Patients were assessed using the modified Harris Hip Score (MHHS) pre- and post-operatively, and statistical significance determined by Student's t-test. We report the mid-term results of 43 patients with femoroacetabular impingement who have undergone this technique for re-attachment of delaminated chondral flaps. There was a statistically significant improvement in MHHS at a mean of 28 months (16 to 42 months) after surgery (p<0.0001). The MHHS for pain improved significantly from 21.8 (95% CI 19.0 to 24.7) pre-operatively to 35.8 (95% CI 32.6 to 38.9) post-operatively (p<0.0001). The MHHS for function also showed significant, although more modest, improvements from 40.0 (95% CI 37.7 to 42.3) pre-operatively to 43.6 (95% CI 41.4 to 45.8) post-operatively (p=0.0006). There were three patients who had early (within 12 months of the index procedure) revision arthroscopy for iliopsoas pathology. Arthroscopic repair of delaminated acetabular articular cartilage using fibrin adhesive is a useful technique in the treatment of early cartilage damage. We have seen encouraging mid-term results, although further studies are warranted.
