A new reconstruction of the patellar tendon was performed in a 43-year-old patient who lost tendon and tibial tuberosity after a wide tumor resection for low-grade myofibroblastic sarcoma of the parapatellar tendon. In this technique, the patellar tendon was anatomically reconstructed using a fascia lata attached to the iliac bone. The iliac bone was fixed to the tibial bony trough with absorba...

OBJECTIVES To evaluate the mechanical properties of the distal cortical hinge associated with a new osteotomy design for the Modified Maquet Technique (MMT). STUDY DESIGN Ex vivo mechanical study. METHODS The osteotomy was started 10 mm caudal to the tibial tuberosity and extended over 150% of the length of the tibial crest; it was slightly curved distally to stay at a distance of 2 to 4 mm...

OBJECTIVE To assess the effect of 9 mm tibial tuberosity advancement (TTA) on cranial tibial translation (CTT) in a cranial cruciate ligament (CCL)-deficient canine stifle model. STUDY DESIGN In vitro cadaveric study. ANIMALS Canine pelvic limbs (n=12). METHODS Each stifle was placed in a jig at 135 degrees with a simulated quadriceps force and tibial axial force. CTT distance was measure...

OBJECTIVE This in vivo study qualitatively describes the sagittal motion pattern of the cranial cruciate ligament (CrCL) insufficient canine stifle in operated and unoperated joints with cranio-caudal laxity on palpation. MATERIAL AND METHODS Sagittal stifle kinematics were recorded in vivo in dogs (> 15 kg BW) with unilateral (n = 7) or bilateral (n = 6) complete CrCL rupture and positive cr...

Abstract Objective To assess the role of proximodistal and caudocranial relative position patellar ligament insertion on tibia length‐to‐patellar length ratio (PLL:PL) in small‐breed dogs with without grade II medial luxation (MPL). Study Design Retrospective study. Sample Population Dogs weighing ≤15 kg, including 43 stifles MPL 34 control stifles. Methods The was determined as a using vertica...

INTRODUCTION Fractures of the proximal tibial epiphysis rare. It has been estimated that fractures of the upper tibial epiphysis account for 0.5-3.1% of all epiphyseal injuries. Who had no neurovascular deficit, with fixed extension deformity at the left knee was treated early with closed reduction techniques. CASE REPORT We present a case of a 16-year-old boy who while playing cricket on the...

BACKGROUND Many osteotomy methods and fixation types have been used to correct the misalignment observed in tibia vara and to achieve a more uniform distribution of weight across the knee joint. PURPOSE The aim of this study is to test the efficacy and safety of a modified closing wedge high tibial osteotomy (CWHTO) procedure for tibia vara. METHODS In this prospective study, young adults w...

Articular geometry of the tibia has been studied in relation to the functional axis and extra-articular bone landmarks, using a Cartesian coordinate system. Thirty-one cadaver limbs were used, 26 of them paired. The donor age range was 61 to 89 years (17 females, 14 males), none of whom showed evidence of significant arthritic deterioration. Most linear parameters were greater in males than fem...

PURPOSE To assess the outcome of unreamed intramedullary nailing through the lateralised entry point using oblique proximal and biplanar distal interlocking screws. METHODS 15 men and 3 women aged 25 to 58 (mean, 37) years underwent unreamed intramedullary nailing with oblique proximal and biplanar distal interlocking screws for proximal third metaphyseal tibial fractures. The entry point was...

A 16-year-old male had simultaneous bilateral tibial tubercle avulsion fractures after making a sudden stop while running at full speed. The left knee injury (type V) was minimally displaced, was treated conservatively with closed reduction, and the patient recovered uneventfully. The right tibial tubercle injury was unusual. The tuberosity and anterior aspect of the proximal epiphysis remained...
