RESUMEN
PURPOSE: To perform a multinational survey and identify patterns in capsular management at the time of hip arthroscopy. METHODS: An anonymous, nonvalidated survey was distributed by the American Orthopaedic Society for Sports Medicine; Arthroscopy Association of North America; European Society of Sports Traumatology, Knee Surgery & Arthroscopy; International Society for Hip Arthroscopy; and Turkish Society of Sports Traumatology, Arthroscopy, and Knee Surgery. The questions were broken down into 6 categories: demographic characteristics, capsulotomy preference, traction stitches, capsular closure, postoperative rehabilitation, and postoperative complications. RESULTS: The survey was completed by 157 surgeons. Surgeons who performed half or full T-type capsulotomies had 2.4 higher odds of using traction sutures for managing both the peripheral and central compartments during hip arthroscopy for femoroacetabular impingement (P = .024). Surgeons who believed that there was sufficient literature regarding the importance of hip capsular closure had 1.9 higher odds of routinely performing complete closure of the capsule (P = .044). Additionally, surgeons who practiced in the United States had 8.1 higher odds of routinely closing the capsule relative to international surgeons (P < .001). Moreover, surgeons who received hip arthroscopy training in residency or fellowship had 2.4 higher odds of closing the capsule completely compared with surgeons who did not have exposure to hip arthroscopy during their training (P = .009). CONCLUSIONS: Geographic and surgeon-related variables correlate with capsular management preferences during hip arthroscopy. Surgeons who perform half or full T-capsulotomies more often use traction stitches for managing both the peripheral and central compartments. Surgeons performing routine capsular closure are more likely to believe that sufficient evidence is available to support the practice, with surgeons in the United States being more likely to perform routine capsular closure in comparison to their international colleagues. CLINICAL RELEVANCE: As the field of hip preservation continues to evolve, capsular management will likely continue to play an important role in access, instrumentation, and postoperative outcomes.
RESUMEN
Several factors contribute to the greater complexity of revision anterior cruciate ligament reconstruction compared with primary anterior cruciate ligament reconstructive surgery. Prior tunnels and hardware may compromise revision tunnel placement and secure fixation. This may necessitate two-stage revision or specific techniques to achieve anatomic revision tunnels. Prior autograft use may limit graft options. Individuals with a failed anterior cruciate ligament reconstruction are more likely to have risk factors for further failure. These may include malalignment, occult instability, knee hyperextension, or increased tibial slope. There are also higher rates of meniscus and cartilage injuries in revision anterior cruciate ligament reconstruction that may require intervention. Successful revision anterior cruciate ligament reconstruction requires thoughtful preoperative planning along with multiple potential intraoperative plans depending on the pathology encountered. It is important to provide the orthopaedic surgeon with an up-to-date, evidence-based overview of how to approach and execute a successful revision anterior cruciate ligament reconstruction.

PURPOSE: Despite the recent increase in the use of quadriceps tendon (QT) autograft in anterior cruciate ligament reconstruction (ACLR); however, there remains a paucity of literature evaluating the postoperative morphology of the QT. The present study aimed to determine the postoperative morphologic change of the QT at a minimum of 2 years following harvesting during ACLR. METHODS: Patients who underwent ACLR with QT autograft and underwent magnetic resonance imaging (MRI) at a minimum of 2 years following harvesting were retrospectively included in the study. The anterior-to-posterior (A-P) thickness, medial-to-lateral (M-L) width, cross-sectional area (CSA), and signal/noise quotient (SNQ) of the QT were assessed at 5 mm, 15 mm, and 30 mm proximal to the superior pole of the patella on MRI. The CSA was adjusted by the angle between the QT and the plane of the axial cut based on a cosine function (adjusted CSA). The A-P thickness, M-L width, adjusted CSA, and SNQ were compared pre- and postoperatively. In addition, defects or scar tissue formation in the harvest site were investigated on postoperative MRI. RESULTS: Thirty patients were recruited for the study. The mean duration between postoperative MRI and surgery was 2.8 ± 1.1 years. The mean A-P thickness was 10.3% and 11.9% larger postoperatively at 5 mm and 15 mm, respectively. The mean M-L width was 7.3% and 6.5% smaller postoperatively at 5 mm and 15 mm, respectively. There were no significant differences in the adjusted CSA between pre- and post-operative states (275.7 ± 71.6 mm2 vs. 286.7 ± 91.8 mm2, n.s.). There was no significant difference in the postoperative change in the SNQ of the QT at all assessment locations. Defect or scar tissue formation at the harvest site was observed in 4 cases (13.3%), and 5 cases (16.6%), respectively. CONCLUSION: At a minimum of 2 years following QT harvest during ACLR, the QT became slightly thicker and narrower (approximately 11% and 7%, respectively). While the current study demonstrates that QT re-harvesting can be considered due to nearly normalized tendon morphology, future histological and biomechanical studies are required to determine the re-harvesting potential of the QT. LEVEL OF EVIDENCE: IV.

PURPOSE: To perform a systematic review and meta-analysis to investigate the rate of stiffness after multi-ligament knee injury (MLKI) surgery and identify potential risk factors associated with postoperative stiffness. METHODS: This study was conducted in accordance with the 2020 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Registration was done on the PROSPERO International Prospective Register of Systematic Reviews (CRD42022321849). A literature search of PubMed, Ovid, Embase, and Cochrane Library databases was conducted in October 2022 for clinical studies reporting postoperative stiffness after MLKI surgery. A quality assessment was performed using the Methodological Index of Non-Randomized Studies (MINORS) grading system. The following variables were extracted from studies for correlation to postoperative stiffness: study characteristics, cohort demographics, Schenk classification, neurovascular injury, mechanism of injury, external fixator placement, timing of surgery, and concomitant knee injuries. RESULTS: Thirty-six studies comprising 4,159 patients who underwent MLKI surgery met the inclusion criteria, including two Level-II, fourteen Level-III, and twenty Level-IV studies. The average MINOR score of the studies was 14. The stiffness rate after MLKI was found to be 9.8% (95% CI 0.07-0.13; p < 0.01; I2 = 87%), and the risk of postoperative stiffness was significantly lower for patients with two ligaments injured compared to patients with ≥ 3 ligaments injured (OR = 0.45, 95% CI (0.26-0.79), p = 0.005; I2 = 0%). The results of the pooled analysis showed early surgery (< 3 weeks) resulted in significantly increased odds of postoperative stiffness compared with delayed surgery (≥ 3 weeks) (OR = 2.18; 95% CI 1.11-4.25; p = 0.02; I2 = 0%). However, age, gender, body mass index, energy of injury, and neurovascular injury were not associated with an increased risk of postoperative stiffness (n.s.). CONCLUSION: Performing surgery within the first 3 weeks following MLKI, or concomitant injury of ≥ 3 ligaments, are significantly associated with increased risk of postoperative stiffness. These findings can be utilized by surgeons to decide the timing of surgery for MLKI surgeries especially in which ≥ 3 ligaments are injured. LEVEL OF EVIDENCE: Level IV.

PURPOSE: Variations in femoral and tibial bony morphology have been associated with higher clinical grading and increased quantitative tibial translation, but not tibial acceleration, during the pivot shift test following anterior cruciate ligament (ACL) injury. The purpose of this study was to determine the impact of femoral and tibial bony morphology, including a measurement influenced by both parameters (the Lateral Tibiofemoral Articular Distance (LTAD)), on the degree of quantitative tibial acceleration during the pivot shift test and rates of future ACL injury. METHODS: All patients who underwent primary ACL reconstruction from 2014 to 2019 by a senior orthopedic surgeon with available quantitative tibial acceleration data were retrospectively reviewed. All patients underwent a pivot shift examination under anesthesia with a triaxial accelerometer. Measurements of femoral and tibial bony morphology were performed by two fellowship-trained orthopedic surgeons using preoperative magnetic resonance imaging and lateral radiographs. RESULTS: Fifty-one patients were included at a mean follow-up of 4.4 years. The mean quantitative tibial acceleration during the pivot shift was 13.8 m/s2 (range: 4.9-52.0 m/s2). A larger Posterior Condylar Offset Ratio (r = 0.30, p = 0.045), smaller medial-to-lateral width of the medial tibial plateau (r = - 0.29, p = 0.041), lateral tibial plateau (r = - 0.28, p = 0.042), and lateral femoral condyle (r = - 0.29, p = 0.037), and a decreased LTAD (r = - 0.53, p < 0.001) significantly correlated with increased tibial acceleration during the pivot shift. Linear regression analysis demonstrated an increase in tibial acceleration of 1.24 m/s2 for every 1 mm decrease in LTAD. Nine patients (17.6%) sustained ipsilateral graft rupture and 10 patients (19.6%) sustained contralateral ACL rupture. No morphologic measurements were associated with rates of future ACL injury. CONCLUSION: Increased convexity and smaller bony morphology of the lateral femur and tibia were significantly associated with increased tibial acceleration during the pivot shift. Additionally, a measurement, termed the LTAD, was found to have the strongest association with increased tibial acceleration. Based on the results of this study, surgeons can utilize these measurements to preoperatively identify patients at risk of increased rotatory knee instability. LEVEL OF EVIDENCE: Level IV.

PURPOSE: End-stage ankle arthrosis causes severe pain and limited movement. Tibiotalocalcaneal arthrodesis with arthroscopy-assisted hindfoot nailing can be used to achieve a high union rate and low complication rate. We aimed to examine the early- and mid-term results of patients treated with this technique from various perspectives and to evaluate them by comparing them with the current literature. METHODS: Data were collected from 25 patients who met the established criteria and underwent TTCA with arthroscopic-assisted hindfoot nailing. In addition to the demographic data of the patients, their clinical and pain scores were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS). Additionally, the union time and complication data during the follow-up period were examined. RESULTS: When the AOFAS and VAS scores of the 25 patients were examined, a significant improvement was observed in the preoperative period and early postoperative period comparisons (p < .001). No significant change was observed between the comparison of the postoperative 12th month and last postoperative control clinical scores. While the union rate of the patients was observed to be 92%, the average union time was 13.1 ± 3.5 weeks. During follow-up, peri-implant fracture, deep infection, and non-union were observed in one patient each (12%). CONCLUSION: The early- and mid-term postoperative results of patients treated with TTCA surgery with posterior approach arthroscopic-assisted hindfoot nailing show that this technique may be an option with low complication and high union rates for the appropriate group of patients planned for ankle arthrodesis.

The exploration of underlying biological risk factors for anterior cruciate ligament (ACL) injury has generated a substantial body of literature describing the role of bony morphology of the knee. Morphological risk factors, such as poor tibiofemoral joint congruity, a narrow femoral intercondylar notch, and an increased posterior tibial slope (PTS), have been implicated in contributing to knee instability and biomechanical abnormalities. Additionally, investigations into sex-specific differences in bony morphology have unveiled distinct risk profiles for males and females. In light of these findings, surgical considerations for individuals with high-risk bony morphology have been developed. Procedures like anterior closing wedge high tibial osteotomy, aiming to address increased PTS, and lateral extra-articular tenodesis for patients with specific risk factors, have been established. The aim of this review is to provide an overview of the current evidence describing the relationship between bony morphology and ACL injury. Moreover, this review aims to discuss the surgical management and outcomes concerning patients exhibiting high-risk anatomic features.

Background: The timing of return to work (RTW) after anterior cruciate ligament (ACL) reconstruction (ACLR) is a less studied milestone compared with return to sports. Purpose: To systematically review the rate and postoperative timing of RTW after ACLR. Study Design: Systematic review; Level of evidence, 4. Methods: This study was conducted in accordance with the 2020 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. A literature search was performed in PubMed, Embase, Cochrane, and Ovid databases for clinical studies reporting RTW after ACLR, and 806 studies were identified in August 2022. A quality assessment was performed using the Methodological Index of Nonrandomized Studies (MINORS) grading system. The following data were extracted from studies: study characteristics, cohort demographics, ACLR technique, concomitant meniscal and/or cartilage procedures, preoperative patient-reported outcomes, rates of RTW, and days required for RTW after ACLR. Results: A total of 13 studies met inclusion criteria, totaling 1791 patients (86.4% male). Wide variability was observed in the methodological quality of the assessed studies (MINORS score range, 8-17). Hamstring tendon (HT) autograft was used in 76.8% (n = 1377; mean age, 30.5 years old), allograft in 17.1% (n = 308; mean age, 33.1 years old), the ligament advanced reinforcement system in 2.5% (n = 46; mean age, 33.2 years old), bone-patellar tendon-bone autograft in 2% (n = 36; mean age, 28.5 years old), and quadriceps tendon autograft in 1.3% (n = 24; mean age, 24.1 years old). Among the included patients, 99.1% (n = 1781) reported successful RTW after surgery. The mean time to RTW was 84.2 days (range, 31.4-107.1 days) for HT and 69.5 days (range, 49-56.6 days) for allograft. Conclusion: While data regarding work intensity before and after ACL injury were absent, our study results suggested that patients most often RTW within 90 days of surgery. Patients with allograft ACLR may RTW earlier than patients undergoing ACLR with HT autograft.
RESUMEN
OBJECTIVE: The purpose is to compare functional outcomes, return to soccer rates, and revision rates in an all-female soccer player cohort undergoing quadriceps tendon (QT) autograft ACLR versus bone-patellar tendon-bone (BPTB) autograft ACLR. METHODS: Female soccer players who sustained an ACL rupture and underwent primary anatomic, single-bundle ACLR with BPTB autograft or QT autograft were included. Demographic and surgical characteristics were collected. Outcomes of interest included Tegner score, International Knee Documentation Committee (IKDC) score, Marx score, return to soccer rates, and failure rates. RESULTS: Data on 23 patients undergoing BPTB autograft ACLR and 14 undergoing QT autograft ACLR was available. Average age was 18.7 years, and average follow up was 4.8 years. Overall, 76 â% (28/37) returned to soccer and 5.4 â% (2/37) underwent revision ACLR. No major significant differences were found in demographic or surgical characteristics. No differences were found in postoperative IKDC scores, preoperative, postoperative, or change from pre-to postoperative Marx activity scores, or pre-and postoperative Tegner scores between the groups. QT autograft ACLR patients had significantly less change in Tegner scores pre-to postoperatively compared to the BTPB autograft ACLR group (0.6 â± â1.2 versus 2.1 â± â1.8; p â= â0.02). Both groups had similar rates of return to soccer [78 â% (18/23) BPTB autograft ACLR versus 71 â% (10/14) QT autograft ACLR; p â= â0.64] and rates of revision (8.7 % (2/23) BPTB autograft ACLR; 0 % (0/14) QT autograft ACLR. CONCLUSION: Results of this study suggest that BPTB autograft ACLR and QT autograft ACLR produce comparable, successful functional and return to soccer outcomes in this all-female soccer player cohort study. Larger, prospective studies are needed to improve the strength of conclusions and provide more information on the optimal graft choice for female soccer players. Surgeons can use the results of this study to counsel female soccer players on expected outcomes after ACLR. LEVEL OF EVIDENCE: III.

Capsule closure during hip arthroscopy is increasingly being shown to optimize outcomes and minimize complications. Although various techniques and suture configurations have been described, closure of the hip capsule remains a technically challenging step for many hip arthroscopists. The purpose of this Technical Note is to summarize capsular management in arthroscopic hip-preservation surgery and to outline a technique of passing capsule sutures under hip traction. This technique is useful, as it facilitates adequate visualization of the vertical limb of the T capsulotomy and interportal capsulotomy, which is difficult when attempted with the hip out of traction and flexed. Our technique also helps to reduce the risk of iatrogenic cartilage injury during suture passage by increasing the distance between the femoral head and capsule leaflets, or the functional working area for capsule closure.
RESUMEN
Graft selection in anterior cruciate ligament (ACL) reconstruction is critical, as it remains one of the most easily adjustable factors affecting graft rupture and reoperation rates. Commonly used autografts, including hamstring tendon, quadriceps tendon and bone-patellar-tendon-bone, are reported to be biomechanically equivalent or superior compared to the native ACL. Despite this, such grafts are unable to perfectly replicate the complex anatomical and histological characteristics of the native ACL. While there remains inconclusive evidence as to the superiority of one autograft in terms of graft incorporation and maturity, allografts appear to demonstrate slower incorporation and maturity compared to autografts. Graft fixation also affects graft properties and subsequent outcomes, with each technique having unique advantages and disadvantages that should be carefully considered during graft selection.
RESUMEN
Anterior cruciate ligament (ACL) injuries are increasingly common in the adolescent age group. Recent literature has endorsed combining ACL reconstruction with lateral extra-articular procedures to minimize residual rotatory knee instability and reduce the risk of reinjury in this age group. This technique describes a single-bundle combined anatomical ACL reconstruction and lateral extra-articular reinforcement performed with a single iliotibial band autograft. Also this technique allows for the ACL reconstruction and lateral extra-articular stabilization to be performed through a single surgical incision while obtaining autograft tissue without disruption of the extensor or hamstring mechanisms.
RESUMEN
Postoperative patient satisfaction after anterior cruciate ligament reconstruction (ACL-R) is influenced mainly by the degree of pain, the need for reoperation, and functional performance in daily activities and sports. Graft choice has shown to have an influence on postoperative outcomes after ACL-R. While patient reported outcomes measurements do not differ between graft options, evidence shows that normal knee kinematics is not fully restored after ACL-R with an increase in postoperative anterior tibial translation (ATT). Postoperative graft rupture rates seem to favor bone-patella-tendon-bone (BPTB) and quadriceps tendon (QT) autografts over HT or allografts. While return to sports rates seem comparable between different graft types, postoperative extensor strength is reduced in patients with BPTB and QT whereas flexion strength is weakened in patients with HT. Postoperative donor site morbidity is highest in BPTB but comparable between HT and QT. With all graft options having advantages and drawbacks, graft choice must be individualized and chosen in accordance with the patient.
RESUMEN
BACKGROUND: Knee laxity increases with medial meniscectomy in anterior cruciate ligament (ACL)-reconstructed knees; however, the biomechanical effect of an additional lateral extra-articular tenodesis (LET) is unknown. PURPOSE/HYPOTHESIS: The purpose of this study was to determine the kinematic effect of a LET in knees that underwent combined ACL reconstruction (ACL-R) and partial medial meniscus posterior horn (MMPH) meniscectomy. It was hypothesized that the addition of LET would reduce laxity in the ACL-reconstructed knee. STUDY DESIGN: Controlled laboratory study. METHODS: Ten fresh-frozen human cadaveric knees (mean age, 41.5 years) were tested using a robotic system under 3 loads: (1) 89.0 N of anterior tibial (AT) load, (2) 5 N·m of internal rotation (IR) tibial torque, and (3) a simulated pivot shift-a combined valgus of 7 N·m and IR torque of 5 N·m-at 0°, 15°, 30°, 45°, 60°, and 90° of knee flexion. Kinematic data were acquired in 4 states: (1) intact, (2) ACL-R, (3) ACL-R + partial MMPH meniscectomy (MMPH), and (4) ACL-R + partial MMPH meniscectomy + LET (MMPH+LET). RESULTS: In response to AT loading, there was a significant increase seen in AT translation (ATT) in the MMPH state at all knee flexion angles compared with the ACL-R state, with the highest increase at 90° of knee flexion (mean difference, 3.1 mm) (P < .001). Although there was a significant decrease in ATT at 15° of knee flexion with MMPH+LET (P = .022), no significant differences were found at other knee flexion angles (P > .05). In MMPH with IR torque, a significant increase was observed in IR at all knee flexion angles except 90° compared with the ACL-R state (range, 2.8°-4.9°), and this increase was significantly decreased at all flexion angles with the addition of LET (range, 0.7°-1.6°) (P < .05). CONCLUSION: Performing a partial MMPH meniscectomy increased ATT and IR in response to AT and IR loads compared with the isolated ACL-R state in a cadaveric model. However, when the LET procedure was performed after partial MMPH meniscectomy, a significant decrease was seen at all knee flexion angles except 90° in response to IR and torque, and a significant decrease was seen at 15° of knee flexion in response to AT load. CLINICAL RELEVANCE: LET may be a useful adjunct procedure after ACL-R with partial MMPH meniscectomy to reduce knee laxity.

Background: Multiple-revision anterior cruciate ligament reconstruction (ACLR) presents several technical challenges, often due to residual hardware, tunnel widening, malposition, or staged surgeries. Purpose: To compare failure and complication rates between the over-the-top (OTT) and transportal drilling (TD) techniques in patients undergoing surgery for failed revision ACLR. Study Design: Cohort study; Level of evidence, 3. Methods: The medical records of patients with at least 2 revision ACLRs using either the OTT or TD technique were reviewed retrospectively. Data on patient demographics, graft characteristics, number of revisions, concomitant procedures, complications, and failures were collected. Between-group comparisons of continuous and categorical variables were conducted with the independent-samples t test and the Fisher exact or chi-square test, respectively. Results: A total of 101 patients undergoing multiple-revision ACLR with OTT (n = 37, 37%) and TD (n = 64, 63%) techniques were included for analysis. The mean follow-up time was 60 months (range, 12-196 months). There were no significant differences in age, sex, body mass index, laterality, or follow-up length between groups (P > .05). Allograft was the graft used most frequently (n = 64; 67.3%) with no significant differences between groups in graft diameter (P > .05). There were no statistically significant differences between groups regarding rate of concurrent medial and lateral meniscus, cartilage, or lateral extra-articular procedures (P > .05). There was also no significant66 between-group difference in complication rate (OTT: n = 2 [5.4%]; TD: n = 8 [13%]) or graft failure rate (OTT: n = 4 [11%]; TD: n = 14 [22%]) (P > .05 for both). Conclusion: The results of this study showed notably high failure and complication rates in challenging multiple-revision ACLR. Complication and failure rates were similar between techniques, demonstrating that the OTT technique is a valuable alternative that can be used in a revision ACLR, particularly as a single-stage approach when the single-stage TD technique is not possible.
RESUMEN
BACKGROUND: Although the infection rates for bone-patellar tendon-bone autograft (BTB), hamstring tendon autograft (HT), and allograft have been reported previously, there are limited data available for a large cohort of individuals undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) using quadriceps tendon autograft (QT). PURPOSE: The aims of this study are (1) to compare rates of septic arthritis after primary and revision ACLR with QT, BTB, HT, and allograft and (2) to evaluate the association between an infection after ACLR and potential risk factors in a large single-system analysis. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: All ACLR cases performed by 10 high-volume sports medicine fellowship-trained ACL surgeons between January 2000 and January 2022 were retrospectively analyzed. Minimum follow-up was 90 days after ACLR, and all multiligament reconstructions were excluded. Demographic information, surgical variables, infection characteristics, and rate of ACL graft retention were collected for all included patients. Independent samples t test, chi-square test, or Fisher exact tests with adjusted Benjamini-Hochberg post hoc procedure were used for group comparisons. RESULTS: In total, 6652 patients were included in this study. The most commonly used graft was allograft (n = 2491; 37.4%), followed by HT (n = 1743; 26.2%), BTB (n = 1478; 22.2%), and QT (n = 940; 14.1%). The overall postoperative rate of septic arthritis was 0.34% (n = 23). Septic arthritis rates based on graft type were 0.74% (n = 13) for HT, 0.24% (n = 6) for allograft, 0.20% (n = 3) for BTB, and 0.10% (n = 1) for QT. While a statistically significant difference with regard to graft type (P = .01) was observed, no significant relationships were found between postoperative septic arthritis and age, sex, revision ACLR, ACLR surgical technique, and accompanying intra-articular procedures for all septic arthritis patients (P > .05). The average time from the onset of the symptoms of infection to surgical irrigation and debridement (I&D) was 2 days (minimum, 0; maximum, 6). ACL grafts were retained during I&D procedures in all patients with postoperative septic arthritis. CONCLUSION: The postoperative rate of septic arthritis was 0.1% after use of the QT autograft. While graft choice may affect rates of septic arthritis after ACLR, patient characteristics, ACLR technique, revision ACLR, and accompanying intra-articular procedures during ACLR were not associated with postoperative septic arthritis with the numbers available for analysis.

We present a patient who had a common peroneal nerve palsy complication due to anti-embolism stocking compression following total hip arthroplasty (THA) surgery performed via the anterior approach (AA). The patient was a 17-year-old underweight female and have experienced bilateral hip pain for the last 3 years. Pelvic X-rays revealed bilateral osteonecrosis of the femoral head and THA surgery for the left hip via the AA was done. Common peroneal palsy developed due to anti-embolism stocking compression on the first postoperative day, which was confirmed by ultrasonography (USG). The common peroneal nerve returned to full function in the third postoperative month with complete healing and the patient was followed up for 3 years. Several etiologic factors have been reported as the cause of the common peroneal nerve palsy following THA surgery. Common peroneal palsy caused by anti-embolism stocking as in our case is an etiologic factor to be considered by arthroplasty surgeons.
RESUMEN
Background: Soft tissue interposition between a suspensory cortical button and the lateral femoral condyle is the most common cause of postoperative suspensory cortical button migration in patients undergoing anterior cruciate ligament reconstruction (ACLR). Purpose: To investigate the effects of soft tissue interposition and suspensory cortical button migration after ACLR on functional outcomes and graft ligamentization. Study Design: Cohort study; Level of evidence, 3. Methods: Included were 249 patients who underwent single-bundle ACLR with hamstring tendon autografts. To measure soft tissue imposition, the patients were divided into 2 groups: those in whom the suspensory cortical button was in contact with (group 1) or at least 1 mm away from (group 2) the lateral femoral condyle on 1-day postoperative radiographs. To measure suspensory cortical button migration, the patients in group 2 were further divided into 2 subgroups: those with button migration (group M) and those without migration (group non-M) as observed on 12-month postoperative radiographs. Ligamentization was evaluated according to Howell classification (grades 1-4) on 12-month follow-up magnetic resonance imaging scans. Also recorded were preoperative and 24-month postoperative Lysholm and Tegner scores and 24-month postoperative arthrometer measurements for anterior knee laxity. Results: There was no significant difference between groups 1 and 2 or between groups M and non-M in terms of demographic characteristics or additional intra-articular pathologies detected intraoperatively. Normal anterior laxity (<3 mm) was detected in 83.7% of the patients postoperatively, and all patients showed statistically significant pre- to postoperative improvement on the Tegner (from 4.1 to 4.3) and Lysholm (from 44.0 to 89.2) scores (P < .05 for both). No significant difference in postoperative functional results or graft ligamentization was found between either the soft tissue interposition groups (groups 1 and 2) or the suspensory cortical button migration groups (groups M and non-M). Conclusion: Differences between patients in soft tissue interposition and suspensory cortical button migration did not significantly affect postoperative clinical or functional outcomes or graft ligamentization after single-bundle ACLR.
RESUMEN
Purpose Most of the internet users search online on YouTube for their health problems and the treatments. The purpose of this study is to evaluate the quality and the reliability of the videos on YouTube for Carpal tunnel syndrome (CTS). Methods The search was made by typing the keywords "Carpal tunnel syndrome" and/or "CTS" into the YouTube search engine, the first 50 videos on the first three pages of YouTube were evaluated. Of these videos, title, duration, number of views, days since uploaded, view ratio (view per day), number of likes, number of dislikes, video power index (VPI), video source, and video content data were recorded. The Journal of the American Medical Association (JAMA) benchmark criteria were used to evaluate the reliability of videos, where the Global Quality Score (GQS) and Carpal tunnel syndrome-specific score (CTS-SS) were used to evaluate the quality of the videos. Results The mean duration of the videos was 364.12 seconds (min 57, max 1,638) and the total duration of videos was 18,206 seconds. The mean number of views was 140,916.1 (min 10,543, max 1,271,040) and total number of views was 7,045,804. The mean JAMA score was 1.8 (min 1, max 4), the mean GQS was 2.72 (min 1, max 5), and the mean CTS-SS was 4.74 (min 1, max 14). There was no significant effect of video content on VPI, JAMA, GQS, or CTS-SS ( p >0.05). The JAMA, GQS, CT-SS scores of the videos from physicians and academic sources were significantly higher compared with other sources ( p <0.05). Conclusion YouTube is one of the most frequently used resource for patients to get information about their diagnosis and treatment methods and it consists of videos with low reliability and quality for CTS. We believe that the creation of an internet-based information resource, which the patients can refer to is one of the current social responsibilities of the physicians and the academicians. Level of Evidence This is a Level V study.
RESUMEN
Background: Ramp lesions are encountered in 16% to 24% of all anterior cruciate ligament (ACL) ruptures. However, isolated ramp lesions without a ruptured ACL have also been reported. Purpose: To evaluate outcomes after type 3 hidden ramp lesions without ACL rupture were treated with all-inside sutures passed through the standard anterior portal. Study Design: Case series, Level of evidence, 4. Methods: Included were 41 patients (26 female; 63.4%) with isolated type 3 ramp lesions who underwent surgery between January 2017 and January 2019. Patients with concomitant lateral meniscal injuries and revision meniscal surgeries were excluded. We retrospectively recorded patient age, sex, and body mass index (BMI), as well as follow-up periods, comorbidities, and postoperative and early midterm complications. The Lysholm, visual analog scale (VAS) for pain, and International Knee Documentation Committee (IKDC) scores were compared preoperatively to final follow-up. In addition, patients were classified as having either a sedentary or active lifestyle according to Sedentary Behavior Research Network (SBRN) criteria. The Shapiro-Wilk test was used to evaluate the normality of the data, and the Wilcoxon and Mann-Whitney U tests were used to compare preoperative and postoperative outcome scores. The Spearman test was employed to evaluate the correlation between patient variables. Results: The mean follow-up period was at 37.6 (range, 25-49) months. A total of 17 patients (41.46%) had a sedentary lifestyle based on SBRN criteria. All scores improved significantly from preoperatively to final follow-up (VAS, from 8.43 ± 1.53 to 2.34 ± 2.9; Lysholm, from 47.73 ± 17.02 to 85.37 ± 14.01; and IKDC, from 27.12 ± 14.81 to 85.32 ± 8.78; P < .001 for all). Although no significant relationship was established between patient activity level and postoperative Lysholm and IKDC scores, an inverse correlation was observed between BMI and Lysholm (r =-0.9906) and BMI and IKDC (r =-0.9402). Conclusion: Satisfactory postoperative clinical results were obtained in patients with type 3 ramp lesions not accompanied by ACL rupture who were treated with all-inside suturing through standard anterior portals.
