An observational retrospective study on safety and functional outcomes of arthroscopic anterior cruciate ligament reconstruction using Sironix suture button and interference screw

Background: Anterior cruciate ligament (ACL) injury is a persistent orthopaedic condition that affects a wide spectrum of people. ACL reconstruction (ACL-R) stands out as the primary treatment option. Graft fixation with suture buttons and interference screws has proven to be a highly successful and reliable method for ACL-R. In this context, our research aims to assess the safety and functional outcomes of patients who underwent arthroscopic ACL-R using the Sironix suture button and interference screw. Methods: This was a retrospective observational study. Patients who underwent arthroscopic ACL-R using Sironix suture button and interference screw (January 2018-March 2022) were included in the study. Functional outcomes of patients were evaluated using the international knee documentation committee (IKDC) assessment, the Tegner activity scale (TAS), the Lysholm knee scoring scale, the modified knee injury and osteoarthritis outcome score (KOOS) quality of life subscale, and the single assessment numerical evaluation (SANE) score. Adverse events, if any, were recorded. Results: All patients achieved excellent outcome measures for IKDC, Tegner, Lysholm, KOOS, and SANE scores. The mean (SD) IKDC score was 88.76 (7.16), Tegner activity score was 5.9 (1.13), while the Lysholm score was 96.9 (6.56). The overall KOOS score was 93.7 (7.52), and the overall SANE score for the affected joint was 94.5 (7.22). Conclusions: Arthroscopic ACL-R using Sironix implants (Helysis titanium interference screw, Helysis PLDLA+β-TCP interference screw, Infiloop fixed loop UHMWPE suture titanium button, Proloop adjustable loop UHMWPE suture Titanium button, and Titanium suture disc) demonstrated safety and good functional outcomes

Closed reduction and percutaneous pinning of displaced supracondylar fractures of humerus in children with delayed presentation

【Abstract】Objective: Supracondylar fractures of the humerus account for 60% of all the fractures around the pediatric elbow and even in developed countries 18% of patients undergo surgery 48 hours or longer following presentation in the hospital. Management guidelines are not clear yet for these patients who present late. The aim of this prospective study was to evaluate the clinical, radiological and functional outcome following closed reduction and percutaneous pinning of widely displaced supracondylar fractures of the humerus presenting 12 hours or more after injury. Methods: We reviewed the functional and radiological results of closed reduction and percutaneous pinning using crossed K-wires in 40 patients with displaced extension type supracondylar fracture of the humerus (Gartland type III) with a delay of more than 12 hours in presentation. The average age of patients was 4.5 years and the mean delay in presentation was 17.55 hours. Results: Closed reduction and percutaneous pinning was successful in 90% of patients. The mean follow up period was 15 months. The Baumann’s angle was restored within 4 degrees of the unaffected side in all patients. Use of a small medial incision in patients with severe swelling helped us avoid ulnar nerve injury. Using Flynn’s criteria, 38 patients (95%) had an excellent result. Two patients had mild myositis and both had a poor result. None of the patients developed cubitus varus. Conclusion: Closed reduction and crossed pinning of displaced supracondylar fractures of humerus in children is a safe and effective method even with delayed presentation.

Assessing the relationship of the peroneal nerve to the posterolateral corner of the knee and influence of race on its dimensions– A MRI based study in Indian population

The relationship of Common peroneal nerve (CPN) to the posterolateral corner of the knee joint is important for surgeons who perform total knee arthroplasty to avoid injury to the nerve during surgery. This relationship varies among different races on account of anthropometry. This study aims to evaluate the anatomical location of this nerve in Indian patients using an MRI based reference system. 213 knee magnetic resonance images (MRIs) were evaluated in axial plane 8 mm below the joint line for distance of the CPN from the closest posterolateral capsule. The angle of the CPN from the center of the tibial anteroposterior axis and relation of CPN with respect to the popliteus were evaluated. A comparative analysis of these measurements among Caucasian, Chinese and Indian patients was made to evaluate for any differences. The mean distance between the CPN and the knee capsule was 15.55 mm (range, 7.8–26.2 mm). The mean angle of the CPN from the center of the AP axis was 50.1° (range, 38–63). CPN was found to be in line with the popliteus from center of the knee in 62% cases. There was no significant difference among the different races among the measured parameters (p > 0.005). This study establishes a “danger zone” and a “safe zone” to avoid CPN injury in total knee arthroplasty in Indian patients and identifies anatomic landmarks to localize the nerve before the soft-tissues release in order to avoid direct injury

Partial versus total knee arthroplasty for isolated antero-medial osteoarthritis – An analysis of PROMs and satisfaction

Aim: This study aimed to compare the patient-reported functional outcomes and patient satisfaction after medial Unicompartmental Knee Arthroplasty (UKA) versus Total Knee Arthroplasty (TKA), performed for anteromedial osteoarthritis (AMOA) of the knee in patients from an Indian population, at a minimum 3-year follow-up. Methods: This is a prospective matched cohort study (1:2 ratio). One hundred and one UKA cases were matched to 206 TKA cases by propensity score matching for age, body mass index (BMI), gender distribution, and the Charlson Comorbidity Index (CCI). The primary outcome (Oxford knee score, OKS) was assessed at a 3-year follow-up, along with secondary outcomes (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] Score, Forgotten Joint Score (FJS), Anterior Knee Pain (Kujala) score, patient satisfaction, and revision rate at the final follow-up). Results: The UKA group was superior to the TKA group in patient-reported functional outcomes based on the OKS (p = 0.004). Using the FJS score, UKA was more likely to be a forgotten joint compared to TKA (p < 0.001). However, differences in the OKS and FJS did not meet the reported minimal clinically important difference (MCID) thresholds. Quality of life (EuroQol-5D VAS scale) was found to be significantly higher in the UKA group (p < 0.001). Patients in the UKA group were more likely to be very satisfied (75.2%) versus the TKA group (62.1%, p = 0.023). Conclusion: For AMOA, UKA was associated with improved patient satisfaction compared to TKA. Although patient-reported outcome measures were statistically in favour of UKA over TKA, the differences were not clinically significant. Multicenter and randomized studies comparing the two procedures are warranted. Evidence: Level-II Therapeuti
