Acetabular Labral Reconstruction Does Not Demonstrate Superior Biomechanical Properties Compared to Labral Repair or Intact Native Labrum but Is Superior to Labral Excision: A Systematic Review of Cadaveric Studies.

PURPOSE: To systematically review and compare biomechanical properties of labral reconstruction to labral repair, intact native labrum, and labral excision in cadaveric studies. METHODS: A search of the PubMed and Embase databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and checklist. Cadaveric studies focused on hip biomechanics related to intact labrum, labral repair, labral reconstruction, labral augmentation, and labral excision were included. Investigated parameters included biomechanical data measures, such as distraction force, distance to suction seal rupture, peak negative pressure, contact area, and fluid efflux. Review articles, duplicates, technique reports, case reports, opinion articles, articles written in a language other than English, clinical studies focusing on patient-reported outcomes, studies performed in animals, and articles with no abstract available were also excluded. RESULTS: Fourteen cadaveric biomechanical studies were included that compared labral reconstruction to labral repair (4 studies), labral reconstruction to labral excision (4 studies); and evaluation of distractive force of the labrum (3 studies), the distance to suction seal rupture (3 studies), fluid dynamics (2 studies), displacement at peak force (1 study), and stability ratio (1 study). Data pooling was not performed because of methodological heterogenicity of the studies. Labral reconstruction did not outperform labral repair in restoring the hip suction seal or any other biomechanical property. Labral repair significantly prevented greater fluid efflux when compared to labral reconstruction. Labral repair and reconstruction improved the distractive stability of the hip fluid seal from the labral tear and labral excision stage, respectively. Furthermore, labral reconstruction demonstrated to have better biomechanical properties than labral excision. CONCLUSIONS: In cadaveric studies, labral repair or intact native labrum was biomechanically more superior than labral reconstruction; however, labral reconstruction can restore acetabular labral biomechanical properties and was biomechanically superior to labral excision. CLINICAL RELEVANCE: In cadaveric models, labral repair outperforms segmental labral reconstruction in preserving the hip suction seal; nonetheless, segmental labral reconstruction biomechanically outperforms labral excision at time 0.

Dancers Show Significant Improvement in Outcomes and Favorable Return-to-Dance Rates After Primary Hip Arthroscopy With Femoral Head Cartilage Status Being a Predictor of Secondary Surgical Procedures at Mid-Term Follow-Up.

PURPOSE: To report minimum 5-year follow-up patient-reported outcome measurement (PROM) scores and return-to-dance rates in dancers who underwent primary hip arthroscopy and to identify predictors of secondary surgical procedures. METHODS: Prospectively collected data from patients who underwent hip arthroscopy between May 2010 and June 2016 were retrospectively reviewed. Patients were included if they participated in dance at any level 1 year prior to surgery and had preoperative and minimum 5-year follow-up scores consisting of the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale pain score. The exclusion criteria were previous hip conditions, previous ipsilateral hip surgery, Tönnis grade greater than 1, or lateral center-edge angle less than 18°. The minimal clinically important difference (MCID) was reported. Dancers who discontinued dance for reasons other than pain in the operative hip were excluded from the return-to-dance analysis. A logistic regression model was used to identify predictors of secondary surgical procedures. RESULTS: Fifty-one hips (48 female dancers) were included. The average age and average follow-up period were 29.8 ± 17.2 years and 79.1 ± 23.2 months, respectively. Improvement in all PROM scores (P < .001) was reported. Achievement rates of the MCID for the modified Harris Hip Score, Nonarthritic Hip Score, and visual analog scale pain score were 83.3%, 85.7%, and 85.7%, respectively. Revision hip arthroscopy was performed in 5 dancers (9.8%). Conversion to total hip arthroplasty was performed in 4 dancers (7.8%). The return-to-dance rate was 78.6%, with 57.6% returning to the preinjury performance level or a higher level. Higher femoral head Outerbridge grade was identified as a predictor of secondary surgical procedures (P = .045; odds ratio, 6.752 [95% confidence interval, 1.043-43.688]). CONCLUSIONS: After primary hip arthroscopy, dancers experienced significant improvement in all PROM scores collected and achieved the MCID at a high rate at minimum 5-year follow-up. The return-to-dance rate in dancers who did not discontinue dance because of lifestyle transitions was 78.6%, with 57.6% returning to the preinjury performance level or a higher level. Higher femoral head Outerbridge grade was found to be a predictor of secondary surgical procedures. LEVEL OF EVIDENCE: Level IV, case series.

Defining Thresholds and Predictors for Achieving the Patient Acceptable Symptom State for Patient-Reported Outcome Measures After Revision Hip Arthroscopy.

BACKGROUND: The Patient Acceptable Symptom State (PASS) after primary hip arthroscopy has been determined; nonetheless, the PASS still needs to be defined for revision hip arthroscopy. PURPOSE: To define minimum 2-year follow-up PASS thresholds for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), visual analog scale (VAS) for pain, and International Hip Outcome Tool-12 (iHOT-12) after revision hip arthroscopy, and to identify predictors of achieving the PASS. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Data were prospectively collected and retrospectively reviewed for all patients who underwent revision hip arthroscopy between April 2017 and July 2020. Patients were included if they had baseline and minimum 2-year follow-up scores for the mHHS, NAHS, HOS-SSS, VAS for pain, and iHOT-12. PASS was calculated using the anchor-based method. Receiver operating characteristic curve analysis was used to determine the thresholds for the PASS. A multivariate logistic regression was used to identify predictors for achieving the PASS. RESULTS: A total of 318 patients who underwent revision hip arthroscopy met the inclusion criteria. Of those patients, 292 (91.8%) had baseline and minimum 2-year follow-up. Of this group, 68 patients (72.1% female and 27.9% male; mean age, 32.9 years) answered the PASS anchor question. Achievement PASS rates were 58.8%, 41.2%, 52.9%, 60.3%, and 52.9% for the mHHS, NAHS, HOS-SSS, VAS, and iHOT-12, respectively. The area under the curve (AUC) values for the PASS for mHHS, NAHS, HOS-SSS, VAS, and iHOT-12 were 0.912, 0.888, 0.857, 0.903, and 0.871, respectively, indicating excellent discrimination. The PASS for the mHHS was 76 (sensitivity, 0.809; specificity, 0.905), for the NAHS was 86.3 (sensitivity, 0.660; specificity, 1), for the HOS-SSS was 64.3 (sensitivity, 0.745; specificity, 0.905), for the VAS was 3 (sensitivity, 0.830; specificity, 0.905), and for the iHOT-12 was 64.3 (sensitivity, 0.745; specificity, 0.905). Body mass index (BMI) was identified as a significant predictor of achieving PASS for the NAHS (OR, 0.967; 95% CI, 0.940-0.996; P = .027), as patients with a BMI ≤25.4 had 1.03 times higher odds ratio of achieving PASS for the NAHS. CONCLUSION: After revision hip arthroscopy, the minimum 2-year follow-up PASS thresholds for the mHHS, NAHS, HOS-SSS, VAS for pain, and iHOT-12 were 76, 86.3, 64.3, 3, and 64.3, respectively. The odds ratio of achieving PASS for the NAHS was 1.03 times higher for patients with a BMI ≤25.4.

Endoscopic Tendon Compression Bridge Technique for Repair of Partial-Thickness Gluteus Medius Tears With Concomitant Arthroscopy for Labral Tears: Minimum 2-Year Outcomes With Benchmark Control Group.

BACKGROUND: The transtendinous technique has been used to treat partial-thickness gluteus medius tears in the setting of concomitant arthroscopy for labral tears. The tendon compression bridge technique for gluteus medius repair has been developed as an alternative method, providing several advantages; however, comparative studies between the 2 techniques are lacking in the literature. PURPOSE: (1) To evaluate the short-term patient-reported outcomes (PROs) of the tendon compression bridge technique and (2) to compare these findings with short-term PROs of the transtendinous technique. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data were prospectively collected on patients who were followed for a minimum of 2 years after an endoscopic tendon compression bridge procedure for gluteus medius repair in the setting of concomitant hip arthroscopy for labral tears. The following PROs were collected preoperatively and postoperatively: modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, visual analog scale score for pain, and the International Hip Outcome Tool. Clinical outcomes were assessed using the Patient Acceptable Symptom State, minimal clinically important difference, and maximum outcome improvement satisfaction threshold. Patients were propensity matched 1:1 to a cohort that underwent gluteus medius repair using the endoscopic transtendinous technique with concomitant hip arthroscopy. RESULTS: A total of 48 hips (48 patients) that met inclusion criteria (age, 53.3 ± 9.8 years; 92% female; body mass index, 26.7 ± 4.6), with a mean follow-up of 38.5 ± 15.7 months, were matched to 48 hips (46 patients) that underwent gluteus medius repair using the transtendinous technique. Both groups demonstrated significant improvement from preoperative scores to latest follow-up (P < .05). Mean magnitude of improvement and latest follow-up scores were not significantly different between the tendon compression bridge group and the transtendinous group, and the groups demonstrated similar favorable rates of achieving Minimal Clinically Important Difference (79% vs 79%, respectively), Patient Acceptable Symptom State (73% vs 73%, respectively), and Maximum Outcome Improvement Satisfaction threshold (65% vs 58%, respectively) for modified Harris Hip Score (P > .05). Patient satisfaction between groups was similar (8.1 ± 2.2 vs 7.7 ± 2.7, respectively) (P = .475). CONCLUSION: At minimum 2-year follow-up, the endoscopic tendon compression bridge technique for partial-thickness gluteus medius tears, when performed with concomitant hip arthroscopy, was associated with significant improvement in functional outcomes. These postoperative results were comparable with those of a matched cohort that underwent the endoscopic transtendinous technique for partial-thickness gluteus medius tears, suggesting that the tendon compression bridge technique for gluteus medius repair is an effective treatment option for partial-thickness gluteus medius tears.

Periacetabular osteotomy with intraoperative computer-assisted modalities: a systematic review.

The role of intraoperative computer-assisted modalities for periacetabular osteotomy (PAO), as well as the perioperative and post-operative outcomes for these techniques, remains poorly defined. The purpose of this systematic review was to evaluate the techniques and outcomes of intraoperative computer-assisted modalities for PAO. Three databases (PubMed, CINAHL/EBSCOHost and Cochrane) were searched for clinical studies reporting on computer-assisted modalities for PAO. Exclusion criteria included small case series (<10 patients), non-English language and studies that did not provide a description of the computer-assisted technique. Data extraction included computer-assisted modalities utilized, surgical techniques, demographics, radiographic findings, perioperative outcomes, patient-reported outcomes (PROs), complications and subsequent surgeries. Nine studies met the inclusion criteria, consisting of 208 patients with average ages ranging from 26 to 38 years. Intraoperative navigation was utilized in seven studies, patient-specific guides in one study and both modalities in one study. Three studies reported significantly less intraoperative radiation exposure (P < 0.01) in computer-assisted versus conventional PAOs. Similar surgical times and estimated blood loss (P > 0.05) were commonly observed between the computer-assisted and conventional groups. The average post-operative lateral center edge angles in patients undergoing computer-assisted PAOs ranged from 27.8° to 37.4°, with six studies reporting similar values (P > 0.05) compared to conventional PAOs. Improved PROs were observed in all six studies that reported preoperative and post-operative values of patients undergoing computer-assisted PAOs. Computer-assisted modalities for PAO include navigated tracking of the free acetabular fragment and surgical instruments, as well as patient-specific cutting guides and rotating templates. Compared to conventional techniques, decreased intraoperative radiation exposure and similar operative lengths were observed with computer-assisted PAOs, although these results should be interpreted with caution due to heterogeneous operative techniques and surgical settings.

Orthobiologics as an adjunct in treatment of femoroacetabular impingement syndrome: cell-based therapies facilitate improved postoperative outcomes in the setting of acetabular chondral lesions-a systematic review.

PURPOSE: To evaluate studies utilizing orthobiologics in the management of femoroacetabular impingement syndrome (FAIS) to (1) assess the indications for usage, and (2) analyze patient-reported outcome measures (PROM) following treatment. It was hypothesized that orthobiologics would (1) be utilized for symptomatic FAIS in the setting of labral or chondral pathology, and (2) improve PROM at most recent follow-up. METHODS: The Pubmed, Ovid Medline, Cochrane, and Web of Science databases were searched for clinical studies evaluating orthobiologics [hyaluronic acid (HA), platelet-rich plasma (PRP), or cell-based therapy (CBT) for treatment of FAIS. Exclusion criteria included orthobiologics used in conjunction with cartilage transfer or scaffolding procedures and a primary indication other than FAIS. Data collection included patient demographics, indications, and baseline and most recent PROM. RESULTS: Eleven studies (one level I, four level II, four level III, and two level IV evidence) met inclusion criteria, consisting of 440 patients with mean ages ranging from 32.8 to 47 years. All 11 studies demonstrated an improvement in PROM from baseline to most-recent follow-up. Four studies administered PRP either intraoperatively or the day after surgery as an adjunct to labral repair. CBT was used intraoperatively in the setting of acetabular chondral lesions (three studies) and labral repair (one study). When comparing to a control group at most recent follow-up, three PRP cohorts demonstrated similar PROM (n.s.), while one PRP group exhibited worse visual analog pain scores (2.5 vs. 3.4, p = 0.005) and modified Harris Hip Scores (mHHS) (82.6 vs. 78.7, p = 0.049). The four CBT studies reported favorable results compared to a control group, with a significantly higher mHHS at most recent follow-up or mean improvement from baseline in Hip Outcome Score-Activities of Daily Living (p < 0.05). Three studies reported on HA, which was utilized exclusively in the nonoperative setting. CONCLUSIONS: Intraoperative PRP and CBT have been commonly reported in the setting of hip arthroscopy for labral repairs and acetabular chondral lesions, respectively. The CBT cohorts demonstrated more favorable PROM at most recent follow-up when compared to a control group, though these results should be interpreted with caution due to heterogeneity of orthobiologic preparations. LEVEL OF EVIDENCE: IV.

Revision Rates After Primary Allograft ACL Reconstruction by Allograft Tissue Type in Older Patients.

Background: While there is extensive literature on the use of allograft versus autograft in anterior cruciate ligament (ACL) reconstruction, there is limited clinical evidence to guide the surgeon in choice of allograft tissue type. Purpose: To assess the revision rate after primary ACL reconstruction with allograft and to compare revision rates based on allograft tissue type and characteristics. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent primary allograft ACL reconstructions at a single academic institution between 2015 and 2019 and who had minimum 2-year follow-up were included. Exclusion criteria were missing surgical or allograft tissue type data. Demographics, operative details, and subsequent surgical procedures were collected. Allograft details included graft tissue type (Achilles, bone-patellar tendon-bone [BTB], tibialis anterior or posterior, semitendinosus, unspecified soft tissue), allograft category (all-soft tissue vs bone block), donor age, irradiation duration and intensity, and chemical cleansing process. Revision rates were calculated and compared by allograft characteristics. Results: Included were 418 patients (age, 39 ± 12 years; body mass index, 30 ± 9 kg/m2). The revision rate was 3% (11/418) at a mean follow-up of 4.9 ± 1.4 years. There were no differences in revision rate according to allograft tissue type across Achilles tendon (3%; 3/95), BTB (5%; 3/58), tibialis anterior or posterior (3%; 5/162), semitendinosus (0%; 0/46), or unspecified soft tissue (0%; 0/57) (P = .35). There was no difference in revision rate between all-soft tissue versus bone block allograft (6/283 [2%] vs 5/135 [4%], respectively; P = .34). Of the 51% of grafts with irradiation data, all grafts were irradiated, with levels varying from 1.5 to 2.7 Mrad and 82% of grafts having levels of <2.0 Mrad. There was no difference in revision rate between the low-dose and medium-to high-dose irradiation cohorts (4% vs 6%, respectively; P = .64). Conclusion: Similarly low (0%-6%) revision rates after primary ACL reconstruction were seen regardless of allograft tissue type, bone block versus all-soft tissue allograft, and sterilization technique in 418 patients with mean age of 39 years. Surgeons may consider appropriately processed allograft tissue with or without bone block when indicating ACL reconstruction in older patients.

Utility of 3D Planning Software in Understanding Residual Proximal Femoral Deformity for Planning of Revision Hip Arthroscopy.

BACKGROUND: During the early evolution of femoroacetabular impingement (FAI) treatment, undercorrection of femoral deformity was a leading cause of hip arthroscopy failures. As the pendulum has swung, overresection of femoral deformity has increased in prevalence as a cause of persistent hip pain after arthroscopy. Computed tomography (CT) scans are increasingly being used in hip arthroscopy for preoperative planning purposes and may allow for improved 3-dimensional (3D) assessment of complex femoral deformities after previous femoroplasty. PURPOSE: To assess whether CT scans provide additional utility over standard radiographs in understanding proximal femoral morphology in patients being evaluated for revision hip arthroscopy after previous femoroplasty in the setting of FAI. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 3. METHODS: Preoperative CT scans and standard radiographs were obtained in 80 patients who underwent revision hip arthroscopy for FAI. The anteroposterior and Dunn radiographic views were used to assess patients for residual proximal femoral deformity and were compared with the CT scan views using a commercially available software program. Determinations of underresection were made using alpha angle, while overresection was determined according to a previously described technique. Chi-square tests were performed to determine statistical significance between radiographic and CT classifications of overresection, underresection, and concomitant over- and underresection. A kappa value was calculated to determine the agreement between measurements on the radiographs and CT scans. RESULTS: There were 30 patients (37.5%) for whom the CT scans revealed information about femoral morphology that was not detected on the radiographs. The kappa value of agreement was 0.28 between CT and radiographic measurements. Underresected cams were detected in 30 patients (37.5%) on CT scans versus 17 patients (21.3%) on radiographs (P = .024). Overresected cams were detected in 31 patients (38.8%) on CT scans versus 14 patients (17.5%) on radiographs (P = .0049). Concomitant areas of under- and overresection were detected in 12 patients (15.0%) on CT scans versus 3 patients (3.8%) on radiographs (P = .027). CONCLUSION: CT scans with 3D planning software may be more sensitive than traditional radiographic views at detecting aberrant proximal femoral anatomy in the setting of failed FAI surgery. The use of 3D planning software may be considered as an adjunctive tool to better understand complex deformity in the proximal femur for the planning of revision hip arthroscopy.

Editorial Commentary: Evaluate for the Beighton Score and Additional Radiographic Signs of Instability Prior to Proceeding With Hip Arthroscopy in Patients With Combined Borderline Hip Dysplasia and Excessive Femoral Anteversion.

Femoral version abnormalities have been increasingly recognized as a key factor in the pathogenesis of nonarthritic hip pain. Excessive femoral anteversion (EFA), defined as femoral anteversion greater than 20°, has been postulated to create unstable alignment of the hip, which is exacerbated in patients with concomitant borderline hip dysplasia (BHD). The optimal treatment algorithm for hip pain in EFA-BHD patients remains debated, with some surgeons advocating against arthroscopic procedures in isolation owing to the combined instability due to the femoral and acetabular abnormalities. When determining the treatment approach for an EFA-BHD patient, clinicians should discern whether the patient is presenting with symptoms due to femoroacetabular impingement versus hip instability. When addressing symptomatic hip instability, clinicians are encouraged to evaluate for the Beighton score and additional radiographic factors (other than the lateral center-edge angle) suggestive of instability, such as a Tönnis angle greater than 10°, coxa valga, and deficient anterior or posterior acetabular wall coverage. Because the combination of these additional instability findings with EFA-BHD may portend an inferior outcome after arthroscopic treatment in isolation, an open procedure such as periacetabular osteotomy can be a more reliable treatment option for symptomatic hip instability in this cohort.

Inflation-Adjusted Medicare Reimbursement for Hip Arthroscopy Fell by 21.1% on Average Between 2011 and 2022.

Purpose: To examine Medicare reimbursement for hip arthroscopy from 2011 to 2022. Methods: The seven most common procedures performed with hip arthroscopy by a single surgeon were gathered. The Physician Fee Schedule Look-Up Tool was utilized to access financial data of the associated Current Procedural Terminology (CPT) codes. The reimbursement data for each CPT were gathered from the Physician Fee Schedule Look-Up Tool. With the consumer price index database and inflation calculator, reimbursement values were adjusted for inflation to 2022 U.S. dollars. Results: Following an adjustment for inflation, it was found that reimbursement rate for hip arthroscopy procedures on average was 21.1% lower between 2011 and 2022. The average reimbursement per CPT code for the included codes was $899.21 in 2022 compared to inflation adjusted $1,141.45 in 2011, a difference of $242.24. Conclusions: From 2011 to 2022, the average inflation-adjusted Medicare reimbursement has steadily declined for the most common hip arthroscopy procedures. As Medicare is one of the largest insurance payers, these results have substantial financial and clinical implications for orthopaedic surgeons, policy makers, and patients. Level of Evidence: Level IV, economic analysis.

Durable Outcomes After Hip Labral Reconstruction at Minimum 5-Year Follow-Up: A Systematic Review.

PURPOSE: To systematically review and report the mid- to long-term patient-reported outcomes (PROs) after hip labral reconstruction. METHODS: A literature search of the PubMed, Embase, and Cochrane Library databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting mid- to long-term PROs at minimum 5-year follow-up after arthroscopic hip labral reconstruction. A quality assessment was performed using the Methodological Index of Non-Randomized Studies grading system. Data collection included study characteristics, demographics, indications, radiographic metrics, perioperative findings, surgical technique, baseline and most recent PROs, and subsequent surgeries. RESULTS: Four studies met inclusion criteria, with 182 hips (age range, 27.9-38.7 years) undergoing labral reconstruction in primary and revision hip surgery with minimum 5-year follow-up. There were three Level III studies and one Level IV study, with an average Methodological Index of Non-Randomized Studies score of 16.6. All studies cited labral tissue characteristics as a factor for surgical indications, including the quality and/or size of the labrum. Three studies performed segmental labral reconstructions, whereas another study used a circumferential technique. Varying grafts were selected, including hamstring autograft/allograft, ligamentum teres autograft, iliotibial band autograft, and tensor fascia lata autograft. All studies demonstrated improved PROs from baseline to most recent follow-up, with 4 studies reporting modified Harris Hip Score values that increased from baseline (range, 58.9-66.8) to most recent follow-up (range, 80.1-86.3). After labral reconstruction, rates of revision arthroscopy ranged from 4.8% to 13.3% and conversion to total hip arthroplasty ranged from 1.6% to 27%. CONCLUSIONS: Improved PROs were observed in all studies at minimum 5-year follow-up, suggesting that labral reconstruction can offer durable results beyond short-term follow-up. Although surgical indications for all studies included labral tissue characteristics, differing graft selection and surgical techniques were used across studies, limiting the ability to determine an optimal treatment approach. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and IV studies.

Editorial Commentary: Treatment of Concomitant Intra-Articular Pathology in Patients With Greater Trochanteric Pain Syndrome Is Indicated by Provocative Impingement or Instability Physical Examination and Ultrasound-Guided Analgesic Injection Testing.

Endoscopic surgery can be used to address peritrochanteric pathology in patients with greater trochanteric pain syndrome. During management of these patients, surgeons must decide whether adjunctive hip arthroscopy to treat concomitant intra-articular pathology (such as labral tears or chondral lesions) is required, because the prevalence of intra-articular findings may be greater than the clinical significance. A thorough history and physical examination can help distinguish whether the symptoms are arising from a peritrochanteric issue (e.g., gluteal tendinopathy, trochanteric bursitis, external coxa saltans) versus an intra-articular pain generator. Increased symptoms with provocative impingement or instability testing indicate adjunctive hip arthroscopy to address intra-articular abnormalities. In addition, an ultrasound-guided analgesic injection into the hip joint or peritrochanteric region may aid in diagnosis. A patient with partial symptomatic relief from separate injections into both areas is a classic presentation and consistent with a mixed-picture of peritrochanteric and intra-articular pathology, which may be addressed with a combined endoscopic and arthroscopic approach.

Intraoperative Intra-articular Antibiotic Injection Reduces Infection in Shoulder Arthroplasty.

Deep infection is a debilitating complication after shoulder arthroplasty. The authors hypothesized that an intra-articular, intraoperative injection of antibiotics would result in a lower infection rate compared with intravenous antibiotics alone. Before 2007, 164 patients (group A) did not receive intra-articular antibiotics. From 2007 to 2018, 1324 patients (group B) received intra-articular antibiotics. Patients received intra-articular gentamicin at the end of surgery with the addition of 1 g of cefazolin in January 2014. Records were retrospectively reviewed for comorbidities, type of surgery, and infection. The cohort that received intra-articular antibiotics was compared with the cohort that did not to determine the effect of prophylactic intra-articular antibiotic administration in preventing infection. There was 1 deep infection in the antibiotic group compared with 5 in the non-antibiotic group (P<.001). Superficial infections developed in 2 cases of patients treated with antibiotics; there were no superficial infections in patients treated without antibiotics (P=.62). One previous study evaluated intra-articular injection of antibiotics for shoulder arthroplasty and found significantly lower rates of infection with the injection of intra-articular gentamicin. In this retrospective follow-up study, the injection of intra-articular gentamicin or gentamicin and cefazolin effectively decreased rates of postoperative infection. At mean follow-up of 399 days, intra-articular antibiotics at the time of surgery resulted in significantly fewer deep infections. Given the minimal risk of adverse events and minimal cost, this is a valid method of reducing infections in total shoulder arthroplasty. [Orthopedics. 2023;46(5):310-314.].

Periacetabular osteotomy after failed hip arthroscopy demonstrates improved outcomes in a heterogenous patient population: a systematic review.

PURPOSE: To evaluate the literature on patients undergoing periacetabular osteotomy after failed hip arthroscopy (PAO-FHA) for (1) patient demographics and hip morphology, (2) changes in preoperative to postoperative patient-reported outcomes (PROs), and (3) PROs in comparison to primary periacetabular osteotomy (PAO) patients. METHODS: A systematic literature search of Pubmed, CINAHL/Medline, and cochrane databases was performed in accordance with PRISMA guidelines. The search phrase was "(periacetabular osteotomy or PAO or rotational osteotomy) and (hip arthroscopy or arthroscopic)". The titles, abstracts, and full texts were screened for studies on PAO-FHA. Study quality was assessed, and relevant data were collected. A meta-analysis was not performed due to study heterogeneity. RESULTS: The search identified 7 studies, including 151 hips (148 patients, 93.9% female) undergoing PAO-FHA, out of an initial 593 studies, with three Level IV and four Level III studies. Mean time from hip arthroscopy to PAO ranged from 17.0 to 29.6 months. Heterogenous hip morphologies and radiologic findings prior to PAO were observed, though patients most frequently demonstrated moderate-to-severe dysplasia (mean or median lateral center edge angle < 20°) and minimal osteoarthritis (Tönnis grade 0 or 1). In all 5 studies that reported concomitant procedures with PAO, femoral and/or acetabular osteoplasty was performed via arthroscopy or arthrotomy. Following PAO-FHA, radiographic acetabular coverage and PROs improved in all 6 studies that reported postoperative outcomes. All four comparative studies of primary PAO vs. PAO-FHA included patients with mean or median LCEAs < 20°, reporting mixed outcomes for the optimal treatment approach. CONCLUSION: PAO-FHA is reported in a heterogenous patient population that frequently includes hips with moderate-to-severe dysplasia and minimal osteoarthritis. Regardless of hip morphology or concomitant procedures, all studies that reported postoperative outcomes demonstrated improved PROs following PAO-FHA. LEVEL OF EVIDENCE: Level IV.

Periacetabular Osteotomy in Athletes With Symptomatic Hip Dysplasia Allows for Participation in Low-, Moderate-, and High-Impact Sports, With Greater Than 70% Return to Sport for Competitive Athletes: A Systematic Review.

PURPOSE: To systematically review the literature and report the rate of return to sport (RTS) in athletes following periacetabular osteotomy (PAO) for symptomatic hip dysplasia. METHODS: A literature search of the PubMed, Embase, and Cochrane Library databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting on athletes undergoing PAO surgery for symptomatic hip dysplasia. A quality assessment was performed using the Methodological Index of Non-Randomized Studies (MINORS) grading system. Data collection included study characteristics, demographics, radiographic measurements, rate and timing of RTS, baseline and most recent patient-reported outcomes (PROs), and subsequent surgeries. RESULTS: Six studies met inclusion criteria with 341 patients undergoing PAO. There were 2 level III and 4 level IV studies, with an average MINORS score of 11. Preoperative and postoperative lateral center edge angles ranged from 8° to 18° and 23° to 41.3°, respectively. One study reported solely on dancers with a 63% rate of RTS at 1 year postoperatively. Two other studies reported RTS of 80% and 82% for multiple sports, with slightly lower rates (73% and 78%) in competitive athletes. Three studies demonstrated a comparable distribution of sports participation, from the preoperative to postoperative period, in low-impact (61.4% to 72.1% and 63.7% to 85.7%), moderate-impact (10.3% to 21.0% and 4.3% to 25.4%), and high-impact (8.5% to 17.6% and 5.1% to 10.8%) sports. Three studies reported time to RTS after PAO, ranging from 8.8 to 12.8 months. Of the 3 studies noting reasons for not returning to sport, concerns related to the operative hip ranged from 36.4% to 67%. Of the studies that reported both preoperative and postoperative PROs, improvements in all values were observed, with modified Harris Hip Scores and Hip Disability Osteoarthritis Outcome Scores at most recent follow-up ranging from 81 to 95 and 72 to 93, respectively. CONCLUSIONS: In athletes with symptomatic hip dysplasia undergoing PAO, postoperative participation in low-, moderate-, and high-impact sports was observed, with greater than 70% RTS for competitive athletes. These findings suggest that PAO, with appropriate indications, is an efficacious treatment option in this active patient population with severe dysplasia. LEVEL OF EVIDENCE: Level IV, systematic review of level III and IV studies.

Patient-Reported Outcomes Improve at 2-Year Minimum Follow-Up After Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Systematic Review.

PURPOSE: To provide an updated review of recent literature on postoperative outcomes following hip arthroscopy for femoroacetabular impingement syndrome (FAIS), focusing on larger-population studies with a minimum 2-year follow-up published within the last 5 years. METHODS: A literature search of the PubMed, Ovid Medline, Web of Science, and Cochrane databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were screened for clinical studies published from 2017 to 2022 with greater than 100 patients and minimum 2-year follow-up. Exclusion criteria included failure to report postoperative patient-reported outcomes (PROs), no preoperative radiographic measurements, and surgery for pathology other than FAIS. Data collection included study characteristics, patient demographics, radiographic findings, intraoperative findings, procedures performed, postoperative PROs, and subsequent surgeries. RESULTS: Nine studies met inclusion criteria. Mean or median patient ages ranged from 32.3 to 41 years, with 4 studies reporting on greater than 50% female patients. Mean preoperative lateral center edge angles and alpha angles ranged from 30.2° to 37° and from 56.2° to 71°, respectively. Labral repairs (range 69.7%-100%) were performed more commonly than debridements (range 0%-26.3%). All studies demonstrated improved PROs at most recent follow-up. Seven studies reported mean or median modified Harris Hip Scores, with preoperative and postoperative values that ranged from 53.1 to 80 and from 67.4 to 100, respectively. Revision hip arthroscopies and conversions to hip arthroplasty ranged from 0.8% to 11.6% and from 0% to 34%, respectively. CONCLUSIONS: All included studies found improvements in PROs after hip arthroscopy for FAIS at a minimum of 2-year follow-up. Conversion to total hip arthroplasty is most common in older patients at minimum 10-year follow-up. LEVEL OF EVIDENCE: Level IV, systematic review of Level I through IV studies.

Hip Capsular Repair Results in Improved Patient-Reported Outcomes and Survivorship: A Systematic Review of the Literature.

PURPOSE: To determine whether routine capsular closure following hip arthroscopy for femoroacetabular impingement (FAI) in patients without dysplasia results in improved patient-reported outcomes (PROs) and increased survivorship rates. METHODS: A literature search of the PubMed, Embase, and Cochrane Library databases was performed using the Preferred Reporting for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting PROs following arthroscopic hip labral repair for FAI. A quality assessment was performed using the Methodological Index for Non-randomized Studies grading system. Inclusion criteria consisted of comparative clinical studies investigating routine capsular closure with nonclosure in patients undergoing hip arthroscopy for the treatment of FAI and labral tears. Exclusion criteria included non-English language, minimum follow-up of less than 2 years after surgery, technique articles, case reports, noncomparative case series of fewer than 10 patients, failure to report surgical technique, absence of postoperative PROs, or partial repair. Data collection included study characteristics, demographics, indications, radiographic metrics, perioperative findings, surgical technique, baseline and most recent PROs, and subsequent surgeries. RESULTS: A total of 531 articles were reviewed, of which 3 were included with 249 hips that underwent capsular repair and 157 hips that underwent capsulotomy with no repair. There were 2 Level III studies and 1 Level II study, with an average The Methodological Index for Non-randomized Studies score of 16.7. All studies cited FAI and labral tear as an indication for surgery. All studies demonstrated improved PROs from baseline to most recent follow-up. Postoperatively, the repair group reported modified Harris Hip Score values ranging from 80.8 to 87, whereas the nonrepair group reported scores ranging from 76 to 81.7. In addition, the repair group reported postoperative Hip Outcome Score - Sports-Specific Subscale values ranging from 68.1 to 9, whereas the nonrepair group reported scores ranging from 65.3 to 76.1. The studies also reported minimal clinically important difference for modified Harris Hip Score, with the repair group reporting percentages ranging from 71 to 100 and the nonrepair group reporting percentages ranging from 52 to 95.6. All 3 studies also observed a lower rate of hip survivorship in the nonrepair group, ranging from 94.6 to 100 in the repair group and 90.8 to 100 in the nonrepair group. There were no significant differences in the rate of revision arthroscopy between groups. CONCLUSIONS: Patients without dysplasia who undergo capsular repair have greater improvements in PROs and greater survivorship rates at early- and mid-term follow-up than patients who do not undergo capsular repair. LEVEL OF EVIDENCE: III, systematic review of level II and III studies.

Slope-Reducing High Tibial Osteotomy and Over-The-Top Anterior Cruciate Ligament Reconstruction With Achilles Tendon Allograft in Multiple Failed Anterior Cruciate Ligament Reconstruction.

Graft failure is a challenging complication following anterior cruciate ligament reconstruction (ACL-R). Among the multiple anatomic and nonanatomic risk factors contributing to ACL-R failure, there is accumulating evidence that a posterior tibial slope of 12° or greater may predispose patients to graft failure of primary and revision ACL-R. In addition, previously malpositioned or widened tunnels, as well as limited autograft options, pose challenges in the setting of revision ACL-R. This Technical Note describes a technique to correct an increased posterior tibial slope using slope-reducing high tibial osteotomy, and single stage revision ACL-R with Achilles tendon allograft using the over-the-top route, in a single-stage procedure. The surgical technique involves an anterior approach to the proximal tibia, followed by tibial tubercle osteotomy and anterior closing-wedge osteotomy. The posterior cortical osteotomy hinge is left intact below the insertion of the posterior cruciate ligament. Over-the-top revision ACL-R is then performed using an Achilles tendon allograft passed around the posterior aspect of the lateral femoral condyle and fixed onto the lateral femur.

Hip Pain in Ballet Dancers: Evaluation and Management.

Hip and groin injuries are common in ballet dancers, who often begin sport-specific training at a young age. The unique demands of ballet include extreme range of motion, with an emphasis on external rotation and abduction. This creates a distinctive constellation of hip symptoms and pathology in this cohort, which may differ from other flexibility sports. When managing hip symptoms in this cohort, orthopaedic surgeons should consider the unique factors associated with ballet, including ballet-specific movements, morphologic adaptations of the hip, and the culture of the sport. Three common etiologies of hip pain in ballet dancers include femoroacetabular impingement syndrome, hip instability, and extra-articular snapping hip syndrome. First-line treatment often consists of focused physical therapy to strengthen the core and periarticular hip musculature, with surgical management reserved for patients who fail to improve with conservative measures.
