COVID-19 Resulted in Reduction Trainee Bedside Experience, But No Reduction in Surgical Experience.

Purpose: Because of the concerns regarding residency process during the pandemic, this study aimed to investigate the volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room. Methods: This retrospective chart study evaluated variables such as volume of clinical interactions of orthopaedic residents at a tertiary hospital by reporting the number of patients treated in the outpatient clinic, inpatient ward, and operating room, from an orthopaedic department in a tertiary trauma center throughout the COVID-19 pandemic era. Comparing these measures was an indirect evaluation tool for measuring the amount of work completed and clinical exposure gained by the residents. Results: Occupancy percentage, hospitalization days, admissions to the department, and attendance of the outpatient clinic were all decreased during the pandemic. No significant changes were evident in the total number of surgeries nor the number of elective surgeries during the pandemic. Conclusions: Overall, a reduction in overall hospitalization days, admissions to the department, total number of visits in the outpatient clinic, and occupancy percentage of the ward was observed during COVID-19. However, there was no difference in the average number of monthly surgeries between the pre-COVID-19 and COVID-19 timeframes. Level of Evidence: Level III, retrospective comparative review.

Editorial Commentary: In Terms of Hip Arthroscopy Long-term Outcomes, Intra-articular Cartilage Damage Is More Important Than Hip Labral Treatment Method: The Second Habit of Highly Effective Surgeons.

There is a large debate revolving around the optimal surgical management of hip labral tears. Currently, the literature tends to gravitate toward labral repair as the mainstay of treatment, followed by labral reconstruction when repair is not feasible. Some studies assert that there is no difference between labral repair versus debridement, whereas others support repair. Other studies support labral reconstruction. In the end, it is the quality of the cartilage that may be most important. Intra-articular cartilage damage is more important than the labral treatment method when it comes to hip arthroscopy long-term outcomes.

Risk Factors for a Failed Transmetatarsal Amputation in Patients with Diabetes.

BACKGROUND: Transmetatarsal amputation (TMA) is a well-recognized limb-salvage procedure, often indicated for the treatment of diabetic foot infections. Currently, there is no widespread agreement in the literature with regard to the factors associated with failure of TMA. This study aimed to define risk factors for the failure of TMA, defined as below-the-knee or above-the-knee amputation, in patients with diabetes. METHODS: This retrospective cohort study included 341 patients who underwent primary TMA. Patients who had a revision to a higher level (the failed TMA group) were compared with those who did not have failure of the initial amputation (the successful TMA group). RESULTS: This study showed a higher frequency of renal impairment, defined as a high creatinine level and/or a previous kidney transplant or need for dialysis, in the failed TMA group (p = 0.002 for both). Furthermore, a Charlson Comorbidity Index (CCI) threshold value of 7.5 was identified as the optimal predictive value for failure of TMA (p = 0.002), and patients with a CCI of >7.5 had a median time of 1.13 months until the initial amputation failed. CONCLUSIONS: TMA is associated with a high risk of revision. CCI may be used as a preoperative selection criterion, as 71.8% of patients with a CCI of >7.5 had failure of the TMA. LEVEL OF EVIDENCE: Therapeutic Level III . See Instructions for Authors for a complete description of levels of evidence.

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

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

Editorial Commentary: Machine Learning Can Indicate Hip Arthroscopy Procedures, Predict Postoperative Improvement, and Estimate Costs.

Complex statistical approaches are increasingly being used in the orthopaedic literature, and this is especially true in the field of sports medicine. Tools such as machine learning provide the opportunity to analyze certain research areas that would often require the complex assessment of large amounts of data. Generally, decision making is multifactorial and based upon experience, personal capabilities, available utilities, and literature. Given the difficulty associated with determining the optimal patient treatment, many studies have moved toward more complex statistical approaches to create algorithms that take large amounts of data and distill it into a formula that may guide surgeons to better patient outcomes while estimating and even optimizing costs. In the future, this clinical and economic information will play an important role in patient management.

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

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

Personalized Medicine Using Predictive Analytics: A Machine Learning-Based Prognostic Model for Patients Undergoing Hip Arthroscopy.

BACKGROUND: Personalized medicine models to predict outcomes of orthopaedic surgery are scarce. Many have required data that are only available postoperatively, mitigating their usefulness in preoperative decision making. PURPOSE: To establish a method for predictive modeling to enable individualized prognostication and shared decision making based on preoperative patient factors using data from a prospective hip preservation registry. STUDY DESIGN: Cohort study (Prognosis); Level of evidence, 2. METHODS: Preoperative data of 2415 patients undergoing hip arthroscopy for femoroacetabular impingement syndrome between February 2008 and November 2017 were retrospectively analyzed. Two machine-learning analyses were evaluated: Tree-structured survival analysis (TSSA) and Cox proportional hazards modeling for predicting time to event and for computing hazard ratios for survivorship after hip arthroscopy. The Fine-Gray model was similarly used for repeat hip arthroscopy. Variables were selected for inclusion using the minimum Akaike Information Criterion (AIC). The stepwise selection was used for the Cox and Fine-Gray models. A web-based calculator was created based on the final models. RESULTS: Prognostic models were successfully created using Cox proportional hazards modeling and Fine-Gray models for survivorship and repeat hip arthroscopy, respectively. The Harrell C-statistics of the Cox model calculators for survivorship after hip arthroscopy and the Fine-Gray model for repeat hip arthroscopy were 0.848 and 0.662, respectively. Using the AIC, 13 preoperative variables were identified as predictors of survivorship, and 6 variables were identified as predictors for repeat hip arthroscopy. In contrast, the TSSA model performed poorly, resulting in a Harrell C-statistic <0.6, rendering it inaccurate and not interpretable. A web-based calculator was created based on these models. CONCLUSION: This study successfully created an institution-specific machine learning-based prognostic model for predictive analytics in patients undergoing hip arthroscopy. Prognostic models to predict survivorship and the need for repeat surgeries were both adapted into web-based tools to assist the physician with shared decision making. This prognostic model may be useful at other institutions after performing external validation. Additionally, this study may serve as proof of concept for a methodology for the development of patient-specific prognostic models. This methodology may be used to create other predictive analytics models in different realms of orthopaedic surgery, contributing to the evolution from evidence-based medicine to personalized medicine.

Multiple trauma-induced, secondary osteoarthritis, knee Arthroplasty and technology: Conventional approach to an unconventional scenario.

A 49-year-old man was involved in a high-energy motor vehicle accident. Haemodynamic instability with multiple long bone fractures of lower limbs was the hallmarks of the injury. Closed fragmented fracture of left femur shaft and open displaced supracondylar fracture of the contralateral femur. Closed comminuted high-grade fracture of the Tibia plateau (Schatzker VI) was diagnosed bilaterally. 'Orthopaedic damage control' was initiated with bilateral 'cross knee' external fixation, followed by conversion to open reduction internal fixation of all fracture sits at 8 days later. The patient underwent nine subsequent hospitalisations, of which eight involved operative treatment. The interval from admission to last documented surgery was 7 years. The endpoint was total knee arthroplasty (TKA) with mega prosthesis of the left knee and a primary-type TKA in the right knee. Both arthroplasties were non-assisted, conventional procedures. Postoperative Western Onterio and McMaster Universities Arthritis Index (WOMAC) score was 85 at 9-year follow-up from the injury incurred.

Residents' perspective on duty hours at an Israeli tertiary hospital.

BACKGROUND: Specialization in medical professions is considered a challenging and intensive period due to the number and sequence of duty hours. Considering the effect of duty hours on residents, both physically and mentally, several models have been created over the years to address this complexity. The two main model schools aim to decrease the duty hour length and night shift (i.e., night float, NF) frequency. In recent years, duty hours have become a source of disagreement and frustration among the medical community, both residents and attendings. A possible change in the duty hour structure may affect residents in terms of several parameters, such as patient safety, the well-being of the physician and the degree of training of the resident. PURPOSE: (1) To investigate medical residents' perspectives on their duty hours utilizing online questionnaires on their effect on the work environment and (2) to assess residents' preferences in relation to the suggested shortened shift and NF models. METHODS: Questionnaires were emailed to all residents (main residents and fellows) at an Israeli tertiary medical center between March 2020 and April 2020. Questions were scored from 1 (disagree) to 5 (fully agree). RESULTS: Two hundred and sixty residents (227 main residents, 43 fellows) participated in the study (40% female). The score for the degree of balance between work and personal life was low (0.9±1.99). The shortened shift model was perceived by the residents as more compatible with a balanced lifestyle than the NF model (3.77 ± 1.20 and 3.14 ± 1.26, respectively, P < 0.0001). Neither model was considered to risk impairing professional training (2.33 ± 1.45 and 2.47 ± 1.25, respectively, P = 0.12). Overall, 74% of the residents were not willing to lower their income if the decision were made to change models, and 56% were not willing to increase the number of shifts. CONCLUSIONS: There is agreement among residents that shortening shift hours to 16 h would have a positive effect on the balance between personal life and work. In the eyes of residents, the change would not impair their training during residency.

The Inverse Relationship Between Labral Size and Acetabular Coverage: Does It Protect the Cartilage in the Dysplastic Hip?

PURPOSE: The aims of this study were to confirm the relationship between osseous coverage and labral size and to investigate the severity of intra-articular damage in borderline dysplastic hips in correlation to labral size. METHODS: Patients treated with primary hip arthroscopy for symptomatic labral tears between 2010 and 2018 were considered for this study. Patients were included if they had preoperative radiographic measures and intraoperative assessments of the labra and cartilage. The study group was divided into borderline dysplastic and nondysplastic groups via 3 measurements: lateral center edge angle (LCEA), acetabular index (Ax), and anterior center edge angle (ACEA). Undercoverage was defined as LCEA ≤ 25°, Ax ≥ 10°, and ACEA ≤ 20°. The labrum was measured in four quadrants: anterosuperior (AS), anteroinferior (AI), posterosuperior (PS), and posteroinferior (PI). Additionally, to assess cartilage damage in borderline dysplastic hips, hips with average labral size in the top quartile were compared to hips with average labral size in the bottom quartile. RESULTS: A total of 1765 hips (1589 patients) were included in the study. The mean LCEA, Ax, and ACEA between the borderline dysplastic and nondysplastic groups were significantly different (P < .001). According to the Ax classification, there was significant evidence that borderline dysplastic hips had larger labra (P < .05). Among the dysplastic group, there was significantly more cartilage damage according to the Outerbridge classifications along both the acetabulum and femoral head in hips with labra in the upper quartile (P =.011 and .005, respectively). CONCLUSION: An inverse relationship may exist between acetabular depth and labral size. Additionally, specifically in borderline dysplastic hips, a relatively large labrum correlates with worse intra-articular damage compared to borderline dysplastic hips with a relatively small labrum. Larger labral size may indicate a higher degree of instability in patients with borderline dysplasia. LEVEL OF EVIDENCE: Level III, case-control study.

Efficacy of NSAIDs versus radiotherapy for heterotopic ossification prophylaxis following total hip arthroplasty in high-risk patients: a systematic review and meta-analysis.

BACKGROUND: The aims of this systematic review were: (1) to investigate the prophylactic effect of radiotherapy (RT) and NSAIDs in high-risk patients following total hip arthroplasty (THA); and (2) to compare the efficacy of non-selective and COX-II selective NSAIDs in preventing post-THA HO, utilising a meta-analysis of randomised control studies. METHODS: The PubMed, Embase, and Cochrane Databases were searched for articles regarding HO following THA in March 2019. Studies were included if they contained data regarding HO incidence after THA or contained data regarding HO prophylaxis comparison of NSAIDs and/or RT in terms of dosage or duration. RESULTS: 24 studies reported on populations that were not at high-risk for HO. These studies reported between 47.3% and 90.4% of their patient populations had no HO formation; between 2.8% and 52.7% had mild formation; and between 0.0% and 10.4% had severe formation. A total of 13 studies reported on populations at high-risk for HO. Studies analysing RT in high-risk patients reported between 28.6% and 97.4% of patients developed no HO formation; between 1.9% and 66.7% developed mild HO formation; and between 0.0% and 11.9% developed severe HO formation. Studies analysing NSAID treatment among high-risk populations reported between 76.6% and 88.9% had no HO formation; between 11.1% and 23.4% had mild HO formation, and between 0.0% and 1.8% had severe HO formation. 9 studies were identified as randomised control trials and subsequently used for meta-analysis. The relative risk for COX-II in developing any HO after THA was not significantly different compared to non-selective NSAIDs (RR 1.00; CI, 0.801-1.256; p = 0.489). CONCLUSIONS: NSAIDs prophylaxis for HO may have better efficacy than RT in high-risk patients following THA. Non-selective and COX-II selective NSAIDs have comparable efficacy in preventing HO. Factors such as medical comorbidities and side-effect profile should dictate the prophylaxis recommendation.

Comparable Minimum 2-Year Patient-Reported Outcome Scores Between Circumferential and Segmental Labral Reconstruction for the Management of Irreparable Labral Tear and Femoroacetabular Impingement Syndrome in the Primary Setting: A Propensity-Matched Study.

PURPOSE: To compare minimum 2-year follow-up patient-reported outcome scores (PROs) in patients who underwent primary acetabular circumferential and segmental labral reconstruction for irreparable labral tears and femoroacetabular impingement syndrome (FAIS). METHODS: Data were reviewed from August 2010 to December 2017. Patients with primary labral reconstruction and minimum 2-year follow-up 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 were included. Circumferential and segmental reconstruction were selected in each case based on the extent of the labral pathology. Exclusion criteria were previous ipsilateral hip surgery/conditions, dysplasia, or Tönnis grade >1. Patients were propensity matched 1:1 based on age, sex, and body mass index. Secondary surgeries were reported. The P value was set at <.05. RESULTS: In total, 144 hips were eligible, and 17 hips were lost to follow-up, leaving 127 hips (88.2%) for analysis. Eighty hips underwent a segmental reconstruction, and 47 hips underwent a circumferential reconstruction. Forty-seven hips with circumferential reconstruction were matched to 47 hips with segmental reconstruction. The average follow-up and age for the segmental and circumferential groups were 29.0 ± 7.8 and 27.9 ± 7.0 months (P = .732) and 43.1 ± 9.4 and 44.7 ± 10.2 years (P = .442) respectively. The segmental and circumferential groups were 48.9% and 51.1% female, respectively. The groups achieved significant and comparable improvement for all PROs and rates of secondary surgeries. No differences were found for achieving the minimal clinically important difference (MCID) and the patient acceptable symptomatic state (PASS). The MCIDs for the segmental and circumferential groups were 76.7% and 77.8% for the mHHS, 64.9% and 77.8% for the HOS-SSS, 71.1% and 68.9% for the VAS, and 68.9% and 73.9% for the NAHS, respectively. The PASSs for the segmental and circumferential groups were 78.3% and 73.3% for the mHHS, 55.3% and 55.0% for the HOS-SSS, and 75.6% and 71.1% for the International Hip Outcome Tool 12, respectively. CONCLUSIONS: At minimum 2-year follow-up, patients who underwent primary hip arthroscopy for either circumferential or segmental labral reconstruction for irreparable labra and FAIS reported significant improvement and similar postoperative scores for all PROs, with no difference in psychometric outcomes and rate of secondary surgeries. A customized approach, using the extent of the irreparable labral tear, seems to be an appropriate strategy. LEVEL OF EVIDENCE: Level III, retrospective comparative therapeutic trial.

Dunn View Alpha Angle More Useful Than Femoral Head-Neck Offset to Predict Acetabular Cartilage Damage in Patients With Femoroacetabular Impingement Syndrome Undergoing Hip Arthroscopy.

PURPOSE: To identify radiographic measurements and demographics that are predictive of acetabular cartilage damage in patients with femoroacetabular impingement syndrome (FAIS) undergoing hip arthroscopy. More specifically, to compare the predictive value of alpha angle and femoral head-neck offset, as measured on Dunn view radiographs, in determining the preoperative likelihood and severity of acetabular cartilage damage. METHODS: Patients were included if they underwent primary hip arthroscopy for FAIS between February 2008 and June 2020. Exclusion criteria were prior ipsilateral hip conditions, Tönnis grade of osteoarthritis >1, unwilling to participate, missing intraoperative, demographic or radiographic variables of interest, and lateral center-edge angle (LCEA) >40° or ≤25°. Fourteen variables were assessed in a bivariate comparison and analyzed in a multivariate logistic model. The Acetabular Labrum Articular Disruption (ALAD) and Outerbridge (OB) classifications were used to define acetabular cartilage defects. Those without damage or those with mild acetabular cartilage damage belonged to the ALAD/OB ≤2 group and those with severe damage belonged to the ALAD/OB ≥ 3 group. RESULTS: A total of 1485 patients were analyzed, including 1038 patients with ALAD/OB ≤2 and 447 patients with ALAD/OB ≥3. There was a greater proportion of males in the ALAD/OB ≥3 group (64.21% vs 25.82%; P <.001). The multivariate logistic regression selected age, sex, anterior center-edge angle (ACEA), and alpha angle. Every additional degree in the alpha angle was associated with a 6% increase in the odds of severe acetabular cartilage damage (odds ratio [OR], 1.06 [95% confidence interval [CI], 0.12-8.11]). The multivariate analysis did not identify femoral head-neck offset as a predictor. The odds of severe acetabular cartilage damage were 3.73 times higher in males than females (OR, 3.73 [95% CI, 0.01-1705.96]). Higher age was found to increase the likelihood of ALAD/OB ≥3 (OR, 1.04 [95% CI, 0.13-7.75]). CONCLUSIONS: In a multivariate analysis, factors identified as preoperative predictors of acetabular cartilage damage in patients with FAIS were age, sex, ACEA, and alpha angle. Femoral head-neck offset was not predictive, suggesting that Dunn view alpha angle may take precedence as a predictor of acetabular cartilage damage. LEVEL OF EVIDENCE: Level III, cohort study.

Surgeon-Specific Traction Time During Hip Arthroscopy for Primary Labral Repair Can Continue to Decrease After a Substantial Number of Surgeries.

PURPOSE: The purpose of this study was to evaluate the total traction time and traction time as a function of anchors placed (TTAP) for primary labral repair in patients undergoing hip arthroscopy by a single surgeon. METHODS: Patients were included if they received a primary labral repair with or without acetabuloplasty, chondroplasty, or ligamentum teres debridement as part of the treatment for femoroacetabular impingement (FAI). Patients were excluded if they had a previous ipsilateral hip surgery, prior hip conditions, Tönnis grade >1, open procedures, microfracture, ligamentum teres reconstruction, or labral reconstruction. TTAP was calculated by dividing total traction time by the number of anchors placed. RESULTS: 2,350 hips met the inclusion criteria. The mean age and BMI in this cohort were 34.22 years and 25.72 kg/m2, respectively. A total traction time of 60 minutes was first achieved after 268 cases. Mean overall total traction time was 58.16 minutes (95% CI [57.35, 58.97]) and mean TTAP was 16.24 minutes (95% CI [15.93,16.55]) after 2,350 cases. Total traction time plateaued after 374 cases at 55.92 minutes, while TTAP plateaued after 487 cases at 14.93 minutes. CONCLUSION: Surgeons who introduce hip arthroscopy into their practice can expect to see improvements in traction time during the first 500 surgeries performed, as total traction time plateaued after 374 cases and TTAP plateaued after 487 cases. LEVEL OF EVIDENCE: IV: case series.

[ROBOTICS- WHY NOW?]

INTRODUCTION: Total knee arthroplasty is already one of the most successful procedures in orthopedics with high survival rates and excellent post-operative outcomes. Despite these satisfying results, robotic-guided arthroplasty is slowly but surely infiltrating both worldwide and domestic. In Steinfeld et al.'s review "Robotic Total Knee Arthroplasty" the authors navigate through the pros and cons of robotic-guided total knee arthroplasty and try to answer the question: Robotics, why now?

Short-term Outcomes of Concomitant Femoral Derotation Osteotomy and Hip Arthroscopy.

The goal of this study is to report the short-term outcomes of concomitant hip arthroscopy and femoral derotational osteotomy (FRO) to treat femoral malrotation and intra-articular pathology. Data were retrospectively reviewed for patients undergoing concomitant hip arthroscopy and FRO between March 2013 and January 2017. Patients were included if they had a minimum of 1 year of follow-up for modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12) score, 12-item Short Form Health Survey Physical component and Mental component (SF-12 P and SF-12 M, respectively) scores, Veterans RAND 12-item Health Survey Physical and Mental (VR-12 P and VR-12 M, respectively) scores, visual analog scale (VAS) score for pain, and patient satisfaction ratings. Rates for meeting the patient acceptable symptomatic state (PASS) and minimal clinically important difference (MCID) were also recorded. Nine hips were included, and mean follow-up was 36.9 months. Mean preoperative femoral version was 33.0°. Patients underwent 1 or more concomitant procedures, such as labral treatment, capsular plication, acetabuloplasty, or femoroplasty. At latest follow-up, significant improvement was seen for mHHS, NAHS, HOS-SSS, and VAS score. Additionally, rates of meeting the PASS for mHHS, iHOT-12 score, and HOS-SSS were 100%, 88.9%, and 55.6%, respectively. Rates of achieving MCID for mHHS and HOS-SSS were 77.8% and 66.7%, respectively. One hip required revision derotational osteotomy to treat overcorrection, and 3 hips underwent secondary surgery for hardware removal. Concomitant hip arthroscopy and FRO may yield improved outcomes for patients with concurrent intra-articular pathology and excessive femoral anteversion. Considering that no major complications were diagnosed, this procedure is also relatively safe. [Orthopedics. 2021;44(6):e739-e746.].

Circumferential and Segmental Labral Reconstruction: A Systematic Review.

The purposes of this study were to synthesize, report, and compare patient-reported outcomes (PROs) between arthroscopic segmental and circumferential labral reconstruction. A systematic review was performed in February 2019 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) method. Inclusion criteria were levels I to IV evidence, articles in English, arthroscopic labral reconstruction, and PROs data. Exclusion criteria were labral treatment without reconstruction, open surgery, and less than 6-month follow-up. Eleven studies were identified. Nine studies (212 hips) reported outcomes of segmental reconstruction. Two studies (194 hips) reported outcomes of circumferential reconstruction. Significant improvement in PROs at short-term with either segmental or circumferential reconstruction was found. [Orthopedics. 2021;44(6):361-366.].

Modern Suture Anchor Techniques for Gluteus Medius Tear Repair With Concomitant Total Hip Arthroplasty Using the Direct Anterior and Posterior Approaches.

Gluteus medius (GM) tears are currently a well-established source of pain and disability. However, their role in primary total hip arthroplasty (THA) in the setting of osteoarthritis (OA) has been underexamined in the literature. The purpose of this study was to report on short-term patient-reported outcome measurements (PROMs) for patients who underwent concomitant primary THA and GM repair. Data were prospectively collected from September 2011 and June 2017. Inclusion criteria were primary THA along with concomitant GM repair and complete follow-up for the Harris Hip Score, Forgotten Joint Score 12, Veterans RAND 12-item Health Survey both Physical and Mental, 12-item Short Form Survey both Physical and Mental (SF-12 P and SF-12 M), visual analog scale for pain, and patient satisfaction. Patients were excluded if they did not have follow-up. Thirty patients (30 hips) were included. Mean follow-up was 24.2±19.3 months. Twenty-nine (96.7%) patients were female. Mean age was 65.2±7.4 years. Mean body mass index was 31.1±5.9 kg/m2. The posterior approach was used for 16 (53.3%) cases and the anterior approach for the remaining 14 (46.7%). Two (6.7%) patients had a less than 25% tear, 7 (23.3%) had a 25% to 50% tear, 14 (46.7%) had a greater than 50% tear, and 7 (23.3%) had a full-thickness tear. All PROMs except SF-12 M demonstrated significant improvement at latest follow-up. Patients who underwent THA with either the anterior or the posterior approach with concomitant GM repair using modern suture anchor techniques reported favorable PROMs at short-term follow-up.

Arthroscopic Triple Reconstruction in the Hip Joint: Restoration of Soft-Tissue Stabilizers in Revision Surgery for Gross Instability.

Gross hip instability in an active adult with previous normal hip anatomy is usually due to disruption of the static stabilizers of the hip joint. Although such a disruption can result from a high-grade injury, it can be iatrogenic after previous hip arthroscopy. The patient may present with a painful limp and recurrent subluxation sensation in the affected hip joint. Revision hip arthroscopy in this scenario is generally complicated, and it is not uncommon for all the soft-tissue stabilizers to be compromised. The labrum, ligamentum teres (LT), and capsule of the hip joint are often so damaged that reparation is not an option. Reconstruction of the torn LT is an established method to add secondary stability while addressing the labral pathology in the hip joint with microinstability. Concomitant reconstruction of all the static restraints has yet to be described addressing triple instability. This Technical Note presents a stepwise approach, including tips and pearls, for arthroscopic triple reconstruction of the labrum, LT, and capsule. We believe this method is a safe and reproducible way to effectively treat gross hip instability in young patients.
