INTRODUCTION Varus and valgus malalignment of the knee increases the risk of medial and lateral osteoarthritis (OA) progression, respectively [1]. T2 relaxation time correlates with collagen content [2] and water content [3] of cartilage, as well as with the integrity [4] and arrangement [5, 6] of the collagen network. It may provide a sensitive tool to detect early degenerative changes in arti...

BACKGROUND This study described a novel, minimally invasive reconstruction technique of lateral tibial plateau fractures using a three-screw jail technique and compared it to a conventional two-screw osteosynthesis technique. The benefit of an additional screw implanted in the proximal tibia from the anterior at an angle of 90° below the conventional two-screw reconstruction after lateral tibia...

Clinically-relevant features of each bone a. Distal femur – The medial and lateral femoral condyles articulate with the tibia, and the femoral trochlea articulates with the patella. The femoral condyles are separated by a notch called the intercondyloid fossa. b. Proximal tibia – The articular surface is divided into medial and lateral condyles to correspond with those of the femur, separated b...

Patellofemoral osteotomies can provide excellent symptomatic relief for selected patients with isolated patellofemoral osteoarthritis (PFOA). Isolated PFOA is a relatively common disorder, seen in 24% of women and 11% of men over the age of 55 years. In up to 89% of these patients, PFOA occurs at the lateral facet of the patella, and is especially amenable to surgical treatment. Particularly in...

The aim of this study was to analyze clinical and radiologic results of an arthroscopic medial plication with the pullout technique and to define indications and limitations of this procedure for patellar instability. Records of 45 patients treated for patellar instability with arthroscopic medial plication with the pullout technique were reviewed. The mean patient age was 22.8±8.3 years. The t...

BACKGROUND Medial meniscus root tear (MMRT) is a recently recognized yet frequently missed meniscal tear pattern that biomechanically creates an environment approaching meniscal deficiency. HYPOTHESIS/PURPOSE The purpose of this study was to assess the effect of MMRT on tibiofemoral kinematics and arthrokinematics during daily activities by comparing the injured knees of subjects with isolate...

BACKGROUND Ankle valgus is a common deformity in patients with multiple hereditary exostoses (MHE) and a potential risk factor for early degenerative arthritis. In children, medial hemiepiphysiodesis of the distal tibia is a relatively simple surgical technique used to correct this deformity. We present here the first results of applying this procedure using the eight-Plate guided growth system...

Tension in an anterior cruciate ligament graft is greater with the knee in flexion when the angle of the tibial tunnel in the coronal plane is vertical or more perpendicular to the medial joint line of the tibia; however, the relationship of the angle of the tibial tunnel to knee function has not been studied. Greater graft tension may limit knee flexion or stretch the graft and increase anteri...

PURPOSE OF THE STUDY Hemiepiphyseodesis is commonly used to correct a coronal plane knee deformity during childhood. Since 2007 Blount staple method has been replaced by the eight-Plate Guided Growth System. We retrospectively analysed indications, results and complications of older so as compare them with newer system. MATERIAL AND METHODS In period from 2009 2019, total 98 lower extremities 5...

Objective: To report surgical technique, morphometric effects and clinical outcomes for tibial tuberosity transposition-advancement (TTTA), sulcoplasty and para-patellar fascial imbrication for management of concomitant medial patellar luxation (MPL) and cranial cruciate ligament (CCL) disease in 32 dogs. Study design: Case series. Methods: A previous technique for tibial tuberosity advancement...
