Single Bundle Versus Double Bundle Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis.

Background: Anterior cruciate ligament (ACL) tear is considered as one of the most common sport-related musculoskeletal injuries. Double bundle (DB) and single bundle (SB) surgical techniques has been widely adopted for ACL reconstruction. This systematic review aimed to provide updated evidence by comparing the short-term, mid-term, and long-term knee stability and functional outcomes of DB and SB reconstruction techniques. Methods: We searched Medline, Web of Science, and CENTRAL. We have selected randomized controlled trials (RCTs) that compared DB and SB ACL reconstruction techniques for primary isolated ACL tear. We have assessed the following outcomes: pivot shift test, Lachman test, KT-1000/2000 knee ligament arthrometer, Lysholm knee function score, Tegner activity score, and graft failure. We have used the standardized mean difference (SMD) was to summarize the continuous outcomes while risk ratio (RR) was used to summarize the dichotomous outcomes. Results: A total of 34 RCTs that enrolled 2,992 participants deemed eligible. Overall, DB showed significantly better outcomes in terms of pivot shift test (RR = 0.61, 95% confidence interval (CI) 0.49-0.75), Lachman test (RR = 0.77, 95% CI 0.62 to 0.95), and KT 1000/2000 arthrometer (SMD = - 0.21, 95% CI - 0.34 to - 0.08). No discernible difference was found between DB and SB techniques in the overall Lysholm score (SMD = 0.12, 95% CI - 0.03 to 0.27), Tegner score (SMD = 0.03, 95% CI - 0.17 to 0.24), or graft failure rate (RR = 0.78, 95% CI 0.33 to 1.85). Conclusions: Our review suggests that DB ACL reconstruction technique shows significantly better knee stability and functional outcomes than SB at short-term follow-up. However, both techniques exhibit similar outcomes at mid-term and long-term follow-up.

A Case Report of Geyser Sign on Magnetic Resonance Imaging (MRI) in a 65-Year-Old Female Patient.

The geyser sign is the flow of arthrographic contrast or joint fluid from the glenohumeral joint across the acromioclavicular joint (AC) and occurs when fluid erupts from the superior aspect of the AC joint during arthrography. The cyst's pathogenesis is linked to a rotator cuff tear and an increase in the amount of fluid in the cyst. This fluid escapes through a one-way valve created by a defect in the AC joint capsule. The cysts, which are typically painless and rest over the AC joint, cause discomfort. We present a case of a 65-year-old female with a left shoulder mass. The patient presented to the outpatient department with a history of left shoulder mass for six months. She reported an increase in size with no constitutional symptoms. She was treated with surgical excision. Although rotator cuff tears and AC joint deterioration are rather common in medical practice, cystic swelling over the AC joint is a relatively uncommon symptom. Less than 50 cases have been reported to date. AC joint cyst is a mechanical consequence of a progressive and severe rotator cuff tear that can be misinterpreted as a tumor in older people. Imaging, particularly magnetic resonance imaging (MRI), should be used to rule out malignancy and make a precise diagnosis, including recognizing the "Geyser sign" if it is present.

Proposal of a novel predictive radiological method to assess the possibility of closed reduction in late presenting developmental dysplasia of the hip: the femoro-acetabular zones.

Late presentation of developmental dysplasia of the hip (DDH) remains a major orthopedic problem. However, existing management is not standardized and is highly surgeon dependent. The theory behind femoro-acetabular zones (FAZ) system is to find a relationship between acetabular maturity and severity of dislocation in one hand, and the outcome of closed reduction, on the other hand in late presenting cases. A retrospective study was performed on children with untreated DDH that underwent closed treatment. Our series consisted of 65 hips; mean patient age was 24 months (range: 9-30 months) with a minimum follow-up of 3 years. FAZ classification was applied to the pre-reduction pelvic radiograph, while the results were evaluated according to Severin's scoring system. Overall, 37 of 65 hips (57%) achieved a satisfactory outcome (Severin I and II), while 22 hips (33%) were found to be unsatisfactory (Severin III). Six hips (10%) needed an open reduction. FAZ expressed a simple and reliable classification in predicting the success of closed reduction. This novel X-ray-based classification system can easily predict patients with DDH in whom a closed reduction is likely to succeed and defer patients with higher grades to surgical intervention. Yet, its validity has to be verified in larger cohort studies and directly compared to the established International Hip Dysplasia Institute classification.
