BACKGROUND The latest version of the navigation system for anterior cruciate ligament (ACL) reconstruction has the supplementary ability to assess knee stability before and after ACL reconstruction. In this study, we compared navigation data between clinical grades in ACL-deficient knees and also analyzed correlation between clinical grading and navigation data. METHODS 150 ACL deficient knee...

OBJECTIVE To analyze and describe the distance from the popliteal artery to three specific areas of the proximal region of the tibia, with the knee extended, by means of magnetic resonance. METHODS Images of 100 knees of patients who underwent magnetic resonance examinations were analyzed. The location of the popliteal artery was measured in three different areas of the posterior proximal reg...

UNLABELLED BACKGROUND Achieving precise implant alignment is crucial for producing good outcomes after total knee arthroplasty (TKA). We introduce a simple method for confirming the accuracy of tibial osteotomy during TKA. FINDINGS Two metallic markers were placed on the skin 20 cm apart, one on the tibial tuberosity and other on the tibial crest, points that are easily identified and palp...

Instability of the patella is a relatively frequent occurrence in adolescents. Its pathogenesis, which is multi-factorial, is still much debated. Stability of the patella is guaranteed by a delicate balance of a series of factors (osteo-cartilaginous, ligamentous and muscular), and it is not surprising that alteration of one or more of these can lead to pathological conditions that can range fr...

BACKGROUND Fractures of the humeral greater tuberosity (GT) are a frequent injury progressively treated with arthroscopic suture anchor repair. Yet, no biomechanical study has been performed comparing fixation strength of arthroscopic single- (SR) vs. double row (DR) fixation. METHODS Standardized fractures of the greater tuberosity were created in 12 fresh frozen proximal humeri. After rando...

Anterior knee pain is a frequent clinical problem. It provides a common challenge to diagnose and manage. Basic science studies have provided insight into the origin of anterior knee pain and refined understanding of the anatomy. Clinical evaluation has progressively focused on the contribution of the entire lower extremity to patellofemoral function. Nonsurgical management has been refined by ...

Fractures of the Proximal tibial epiphysis are rare. We report a case of proximal tibial epiphyseal fracture with completely separated and displaced physis . The injury was a result of high speed road traffic accident. The fracture displacement was such that it was difficult to put it in any existing classification system except poland type 4. The injury has a high risk of neurovascular comprom...

Large glenoid fractures are relatively uncommon with shoulder dislocation. Simultaneous glenoid and greater tuberosity fractures with anterior shoulder dislocation are very rare. We report on a 48-year right-handed male who sustained a fall during skiing. He had anterior shoulder dislocation combined with large glenoid fracture and greater tuberosity fracture. He was treated surgically with fix...

Custom-made and off-the-shelf functional knee orthoses from four manufacturers were evaluated. Anterior tibial translation testing was performed using a pneumatic mechanical surrogated knee. The mechanical surrogate was interfaced with a servohydraulic materials testing system, which applied all anterior/posterior displacements to an ultimate anterior load of 400 N. Comparison of the individual...
