Male porcine stifle joint: Insights into osteology and meniscus anatomy for orthopaedic research.

Introduction: Utilizing large animal model like male pig for biomechanical studies offers a cost-effective approach to understanding human joint and tissue mechanics. Our study explores the osteology and meniscus anatomy of the male porcine stifle joint and compares it to human knee joint parameters, aiming to provide a valuable reference for orthopaedic research and surgical training.

Methods: We examined 60 male porcine stifle joints and analyzed their menisci and bones.

Anterior variable angle locking neutralisation plate superiority over traditional tension band wiring for treating transverse patella fractures.

Purpose: This paper investigates the biomechanical benefits of using hybrid constructs that combine cannulated screws with tension band wiring (TBW) cerclage compared to cannulated screws with anterior Variable Angle locking neutralisation plates (VA LNP). These enhancements can bear heavier loads and maintain the repaired patella's integrity, in contrast to traditional methods.

Method: Eighteen fresh-frozen human cadaver patellae were carefully fractured transversely at their midpoints using a saw.

Effects of various load magnitudes on ACL: an in vitro study using adolescent porcine stifle joints.

Introduction: The escalating incidence of anterior cruciate ligament (ACL) injuries, particularly among adolescents, is a pressing concern. The study of ACL biomechanics in this demographic presents challenges due to the scarcity of cadaveric specimens. This research endeavors to validate the adolescent porcine stifle joint as a fitting model for ACL studies.

Arthroscopic and Radiographic Features Distinguish Femoral Head Deformity from Idiopathic Cam, Slipped Capital Femoral Epiphysis, and Recurrent Cam After Slipped Epiphysis.

Introduction: Hip impingement from slipped epiphysis and idiopathic cam is well known but not fully differentiated. Idiopathic cam can be a result of an undiagnosed slip. The mechanism of remodeling of slipped epiphysis deformity has also been controversial.

Comparative study of locking neutralization plate construct versus tension band wiring with a cannulated screw for patella fractures: experimental and finite element analysis.

Transverse patella fractures, accounting for approximately 1% of Orthopedic injuries, pose intricate challenges due to their vital role in knee mechanics. This study aimed to compare the biomechanical performance of a construct, integrating cannulated screws and an anterior locking neutralization plate, with the conventional tension band wiring technique for treating these fractures. Experimental testing and Finite Element Analysis were employed to evaluate the constructs and gain profound insights into their mechanical behavior.

The current trend of proximal tibiofibular ganglion cyst: A summary of 7 case series and 61 case reports.

Purpose: To review the different types of ganglion cysts surrounding the proximal tibio-fibular joint, their management options, outcomes, and recurrence.

Design: Descriptive analytical review.

Results: 7 case series consisting of a total of 159 patients and 61 case reports consisting of 80 patients (with three patients having bilateral pathology) were included in this review.

Management of Chronic Patella Tendon Tear with Heterotopic Ossifications: A Case Report and Pictorial Review of Various Techniques in Contemporary Practice.

Purpose: To review reliable techniques for reconstructing or repairing chronic patella tendon tears and describe the unique case report of chronic patellar tendon tear with heterotopic ossification (HO).

Case Description: A 47-year-old male presented with chronic patellar tendon tears with HO, resulting in an inability to extend the right knee fully. Krackow suture repair augmented by autograft semitendinosus and gracilis was employed after debriding intra-substance patella tendon HO and fibrotic tissue.

Hip Joint Instability After Surgery Performed Through the Surgical Dislocation Approach.

Background: Safe surgical dislocation of the hip is a versatile approach to the hip joint with a low complication rate. Hip joint instability is a devastating complication with poor prognosis.

Methods: All hips treated surgically through the safe surgical dislocation approach were entered in a database and the complication of hip joint instability was studied prospectively from 2000 to 2021.

Pediatric cervical Hemivertebrae - A Rare Case Presentation in a 3-Year-Old Child.

Introduction: Hemi vertebrae are very rarely seen at a cervical level which results in kyphotic deformity without coronal tilt. Vertebral formation defects have been the basis of congenital kyphoscoliosis deformity in the pediatric age group. Cervical spine kyphosis more than 10° along with kinking of cord at a single level results in neurodeficits which require urgent management on the lines of decompression, realignment, and bony fusion to prevent recurrence and failure and to achieve superior outcomes.
