Return to Work After Anterior Cruciate Ligament Reconstruction: A Systematic Review.

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.

Capsular Management at the Time of Hip Arthroscopy for Femoroacetabular Impingement Syndrome Varies With Geography and Surgeon Subspecialty Training: A Cross-Sectional, Multinational Surgeon Survey.

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.

Near complete quadriceps tendon healing 2 years following harvest in 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.

Hip Capsular Closure in Distraction: A Technique to Allow Easier Closure of T and Interportal Capsulotomies.

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.

Failure Rates and Complications After Multiple-Revision ACL Reconstruction: Comparison of the Over-the-Top and Transportal Drilling Techniques.

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.

What it takes to have a high-grade pivot shift-focus on bony morphology.

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.

Early surgery and number of injured ligaments are associated with postoperative stiffness following multi-ligament knee injury surgery: a systematic review and meta-analysis.

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.

What to Do When It Is Anterior Cruciate Ligament Reconstruction Number Two.

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.

Evaluation of the Reliability and Quality of Information in Carpal Tunnel Syndrome Shared on YouTube.

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.

Malignant Tumors of the Foot and Ankle.

BACKGROUND: Surgical treatment is usually required for malignant foot and ankle tumors. In this study, we sought to review factors in treatment that may be associated with morbidity and mortality. METHODS: All malignant foot and ankle tumors at our institution between April 1988 and April 2018 were retrospectively reviewed. The surgical modalities used and clinical outcomes of patients according to the anatomic location (Kirby zone) and clinical stage (Enneking system) of each tumor were described. Extent of surgical resection required, recurrence, and death rates were assessed. RESULTS: Between April 1988 and April 2018, 80 patients with malignant tumors of the foot and ankle were treated at out institution. Mean age of patients was 42.6 (range, 3-89) years. Mean follow-up was 30.2 months (range, 24-120). Tumors were primary in 75 patients (94%) and metastatic from another organ in 5 patients (6%). Tumors originated from bone in 18 patients (22%) and from soft tissue in 63 patients (78%). Synovial sarcoma was the most common soft tissue tumor, and osteosarcoma was the most common osseous tumor.All patients had surgery to resect their tumor. Twenty-one (26%) had unplanned surgical procedures without initial biopsy at an outside institution prior to referral. Those patients were more likely to be treated with amputation or wide excison and free flap surgery (P < .01). The recurrence rate was 50% for the unplanned surgery group and 22% for the planned surgery group. Mortality rate was 10% for the unplanned group and 6% for the planned group. The recurrence and mortality rate was higher in the unplanned group (P = .03). CONCLUSION: Our study suggests that unplanned initial surgeries are associated with higher recurrence and mortality rates and reinforces the notion that these patients should be referred for treatment at a center with specialized expertise in tumor management. LEVEL OF EVIDENCE: Level, IV, retrospective case series.

External and internal hemipelvectomy: A retrospective analysis of 68 cases.

OBJECTIVES: This study aims to investigate the factors that may be associated with surgical site infection and mortality in pelvic resection surgeries. PATIENTS AND METHODS: A total of 68 patients (40 males, 28 females; mean age: 43±16.2 years; range, 11 to 70 years) who underwent internal or external hemipelvectomy between January 2010 and January 2020 were retrospectively analyzed. We reviewed data concerning histopathological diagnosis, surgical technique, pelvic resection type, tumor size, postoperative infection, duration of follow-up, and mortality. RESULTS: The mean follow-up was 45.5±42.2 months. Among 68 patients, 29 (42.6%) cases underwent external hemipelvectomy and 39 (57.4%) cases underwent internal hemipelvectomy. Reconstruction was performed in 14 (20.6%) patients who underwent internal hemipelvectomy. Of all patients, 61 had primary malignant pelvic tumors and two had metastatic pelvic tumors. Of the other five patients, two had a giant cell tumor, two had a pelvic hydatid cyst, and one had an aneurysmal bone cyst. The three most common pelvic tumors were chondrosarcoma (n=25, 36.7%), osteosarcoma (n=13, 19.1%), and Ewing sarcoma (n=8, 11.8%). Surgical site infections were observed in 34 (50.0%) patients. Of 34 patients, 15 (22.1%) had superficial infections and 19 (27.9%) had deep surgical infections. The superficial and deep infection rates were higher in the external hemipelvectomy group compared to internal hemipelvectomy (p=0.02). Patients with postoperative infection had a mean survival period of 36.0 months compared to 79.8 months in patients without infection (p=0.037). The patients treated with internal hemipelvectomy had a mean survival of 97.0 months compared to 25.7 months in patients treated with external hemipelvectomy (p<0.0001). The effect of Enneking stages of malignant pelvic tumors on survival was investigated using the Kaplan-Meier analysis. Cumulative survival decreased, as the stage progressed (p<0.0001). CONCLUSION: The type of surgical technique affects the possibility of postoperative infection. Postoperative infection, surgical method, and stage of the tumor are associated with survival.

Short-Term Outcomes After Treatment of Isolated Hidden Meniscal Ramp Lesions.

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.

Can Anti-embolism Stockings Cause Common Peroneal Nerve Palsy Following Total Hip Arthroplasty Via Anterior Approach? A Case Report.

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.

Comparison of All Arthroscopic Implantation of Chitosan-Based Liquid Scaffold and Hyaluronan-Based Soft Scaffold in the Treatment of Condylar Osteochondral Lesions in the Knee.

Cell-free scaffolds used in cartilage regeneration are produced from different materials. The aim of this study is to compare the clinical and radiological results of two different scaffolds with hyaluronan- or chitosan-based structure used in the treatment of symptomatic condylar osteochondral lesions. The study comprises 69 patients who were operated for osteochondral lesion repair with hyaluronan- (n = 37) or chitosan-based (n = 32) scaffold. The International Knee Documentation Committee (IKDC), Lysholm Knee Scoring Scale and Visual Analog Scale (VAS) scores were collected for both groups at the preoperative and postoperative 3rd, 12th, and 24th months. Magnetic resonance imaging was performed between the 12th and 15th months postoperatively and this with magnetic resonance observation of cartilage repair tissue (MOCART) scoring were compared. Within group assessments demonstrate significant improvement in IKDC, Lysholm, and VAS scores at postoperative 3rd and 12th months. However, in both groups, IKDC, Lysholm and, VAS scores at the postoperative 24th month indicate no significant further improvement, compared with the 12th month results. There was no significant difference between the groups in terms of IKDC, Lysholm, VAS, and MOCART scores at any time period. This study shows that both scaffolds are useful in cartilage regeneration but have no clinical or radiological superiority to each other. Surgeons should select the method with which they feel comfortable. This is a level III, retrospective comparative study.

The Relationship Between Arthroplasty Surgeons' Experience Level and Optimal Cable Tensioning in the Fixation of Extended Trochanteric Osteotomy.

INTRODUCTION: In this study, our aim was to examine the relationship between the arthroplasty surgeons' experience level and their aptitude to adjust the cable tension to the value recommended by the manufacturer when asked to provide fixation with cables in artificial bones that underwent extended trochanteric osteotomy (ETO). MATERIALS AND METHODS: A custom-made cable tensioning device with a microvoltmeter was used to measure the tension values in Newtons (N). An ETO was performed on 4 artificial femur bones. Surgeons at various levels of experience attending the IXth National Arthroplasty Congress were asked to fix the osteotomized fragment using 1.7-mm cables and the tensioning device. The participants' demographic and experience data were investigated and recorded. The surgeons with different level of experience repeated the tensioning test 3 times and the average of these measurements were recorded. RESULTS: In 19 (35.2%) of the 54 participants, the force applied to the cable was found to be greater than the 490.33 N (50 kg) value recommended by the manufacturer. No statistically significant difference was determined between the surgeon's years of experience, the number of cases, and the number of cables used and the tension applied over the recommended maximum value (P = .475, P = .312, and P = .691, respectively). CONCLUSIONS: No significant relationship was found between the arthroplasty surgeon's level of experience and the adjustment of the cable with the correct tension level. For this reason, we believe that the use of tensioning devices with calibrated tension gauges by orthopedic surgeons would help in reducing the number of complications that may occur due to the cable.

The effectiveness of peripheral compartment first access and periportal capsulotomy technique for arthroscopic management of femoroacetabular impingement: A prospective case series.

OBJECTIVE: The aim of this study was to evaluate the functional results of hip arthroscopy for femoroacetabular impingement (FAI) performed via the periportal capsulotomy technique combined with capsular thinning and peripheral compartment first access. METHODS: This prospective study included 34 patients (20 female, 14 male; mean age = 32.3 ± 12.5 years) treated for combined type FAI and labral tears between January 2016 and January 2018. In radiographic evaluation, center-edge angle (CEA) and alpha angle were measured preoperatively and postoperatively. Patients' functional status was assessed at 3, 6, 12, and 24 months using the modified Harris Hip Score (mHHS), Hip Disability and Osteoarthritis Outcome Score - Activities of Daily Living (HOOS-ADL), and Hip Disability and Osteoarthritis Outcome Score - Sports-Specific Subscale (HOOS-SSS), and visual analog scale (VAS). RESULTS: The mean alpha angle decreased from 55.5°±2.9° preoperatively to 48.3° ± 2.6° postoperatively. The mean CEA decreased from 39.2° ± 3.0° preoperatively to 32.9° ± 2.6° postoperatively. The mean duration of surgery was 96.7 ± 21.1 minutes; the mean traction time was 45.5 ± 14.6 minutes. The mean mHHS at the 3rd , 6th, 12th, and 24th months showed a statistically significant increase compared to the preoperative value (P < 0.05). The mean HOOS-ADL and HOOS-SSS at the postoperative 3rd, 6th, and 12th months demonstrated a statistically significant increase compared to the preoperative values (P < 0.05). The same scores measured at the 24th month, however, did not demonstrate a significant increase. The mean VAS scores at the 3rd and 6th months postoperative illustrated a significant decrease compared to the preoperative values (P < 0.05) whereas this significant decrease was not observed at the 12th and 24th months. CONCLUSION: The combined technique of periportal capsulotomy and capsular thinning used in this study seems to be a reliable surgical method with favorable functional results, a low complication rate, and a low risk of hip instability. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

Can headless screw used in fixation of the scaphoid proximal pole fracture be broken after wrist trauma? An unreported complication of scaphoid surgery.

The post-traumatic impairment of blood supply of the scaphoid bones' proximal pole is the subject of controversy in the surgical techniques which would heal this fracture. In a surgery performed with a dorsal approach, the main goal is to make a strong fixation with a small incision and a good implant without disturbing the blood supply of the bone. To date, complications related to surgical treatment of scaphoid proximal pole fractures have been reported in detail. However, there is no other study which presents headless screw failure which placed for the scaphoid proximal pole fracture surgery. Although implant technologies have been developed nowadays, our case report highlights that the endurance of these implants has not been carried out in such proximal pole fractures of the scaphoid, yet. Herein, we present the explanation of a broken headless screw which was placed into the proximal pole fracture of scaphoid, avoiding to affect bone stock of the scaphoid surgical technique. We believe that this surgical technique would be helpful to manage similar difficult situations for orthopedic surgeons.

Poland's syndrome concomitant with congenital proximal and distal radioulnar synostosis: A rare case report.

Radioulnar synostosis is a rare disease which causes supination and pronation restriction as a result of osseous or fibrous connections between the radius and ulna. Radioulnar synostosis includes both congenital and post-traumatic types. Post-traumatic radioulnar synostosis can be seen in the proximal, middle, and distal part of the forearm, depending on the location of the trauma. Congenital proximal radioulnar synostosis occurs as a result of a separation defect between the radius and ulna in the embryonic period. In the presence of congenital proximal radioulnar synostosis, the patient should be evaluated for accompanying syndromes and possible developmental anomalies. In this report, we present a rare case of both proximal and distal radioulnar synostosis. Hypoplasia of the right pectoral muscle mass, hypoplastic appearance of the right nipple, presence of proximal and distal radioulnar synostosis in the right forearm, and accompanying symbrachydactyly suggested Poland syndrome. To the best of our knowledge this is the first case of congenital proximal and distal radioulnar synostosis with Poland syndrome.

Single-Incision, Single Patellar Tunnel For Double-Bundle Medial Patellofemoral Ligament Reconstruction: A Technical Note.

The medial patellofemoral ligament (MPFL) is the main medial stabilizer of the patella, while reconstruction of the ligament is a common surgery performed by orthopedic surgeons. Although several surgical methods have been described regarding MPFL reconstruction, the common goals of these surgeries are to imitate the anatomic features of the native MPFL. In the single-incision and single patellar tunnel and double-bundle MPFL reconstruction technique, we will present the anatomical footprint of the MPFL located in the medial aspect of the patella, which is filled with the graft. In this technique, graft fixation is performed in the femoral tunnel using only one bioabsorbable screw without the need for fixation in the patella.

The increase in paediatric orthopaedic trauma injuries following the end of the curfew during the COVID-19 period.

PURPOSE: The aim of this study was to compare the injury patterns of orthopaedic trauma patients in the paediatric age group who presented to our hospital during and after lifting the curfew due to the pandemic, with the patients of the same age group who presented to our institution during the same time period last year. METHODS: Patients, aged 0 years to 18 years, who presented to our clinic between 21 March 2020 and 31 May 2020 (during curfew) (Group A1, n = 111), between 01 June 2020 and 31 August 2020 (Group A2, n = 214) and during the same periods in 2019 Group B1 (n = 220) and Group B2 (n = 211) were included. Patients with pathological fractures, traumas occurring earlier than the aforementioned date range and those consulted while being hospitalized in another department were excluded from study. Patients' demographics, the department they presented to, the anatomical region affected by trauma, trauma mechanism, the location of trauma, the treatment applied and the length of hospital stay were recorded. RESULTS: The prevalence of outdoor traumas (72.9% versus 61.1%), high-energy traumas (40.1% versus 26.5%), the rate of the patients treated with surgery (28% versus 17.1%) and the rate of admission to the emergency department (90.2% versus 58.3%) were significantly higher in Group A2 when compared with Group B2 (p < 0.05). CONCLUSION: The significant increase was observed in the number of outdoor injuries, high-energy traumas and fracture patterns that require surgical treatment during the first three months following the lift of the curfew, in comparison with the corresponding dates from last year. We think that children's lower extremity muscle strength and neuromuscular control was decreased due to staying home for a prolonged period of time. LEVEL OF EVIDENCE: Level III, Case-control study.
