BACKGROUND The Koshino (KI) and Caton-Deschamps (CDI) indices are used to measure patellar height in children, with the CDI showing excellent reliability in typically developing (TD) children. Reliability of such measures in children with cerebral palsy (CP) and spina bifida (SB) is unknown. METHODS Lateral knee radiographs were reviewed retrospectively for children with TD (n = 49), CP (n = ...

BACKGROUND The femoral peel to expose a difficult knee was first described by Windsor and Insall in the mid-1980s. This surgical exposure consists of a complete soft tissue subperiosteal peel of the femur. It includes the detachment of the origin of the medial and lateral collateral ligaments. QUESTIONS/PURPOSES We investigated the utility of a surgical exposure, the modified femoral peel, fo...

BACKGROUND Patellar stabilizing braces are used to alleviate pain and prevent subluxation/dislocation by having biomechanical effects in terms of improved patellar tracking. The purpose of this study is to analyze the effects of the dynamic patellar realignment brace, Patella Pro (Otto Bock GmbH, Duderstadt, Germany), on disease determinants in subjects with patellofemoral instability using upr...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2015-209942 DESCRIPTION Quadriceps tendon (QT) ruptures are uncommon injuries that predominantly affect middle-aged men. Ruptures occur as a result of direct or indirect trauma to the knee with a powerful eccentric contraction of the QT being the most frequent ca...

A 15-year-old girl presented with a primary lateral patella dislocationof her left knee after she slippedoff a starting block and struck the medial aspect of her knee. No reduction was required, the patellar dislocation spontaneously reducedwith gentle knee extension prior to evaluation. Patellofemoral anatomy measurements demonstrated an Insall–Salvati ratio of 1.5, a Caton–Deschamps index of ...

INTRODUCTION Although patellar tendon injuries are common but chronic patellar tendon rupture are rare injuries but severely disabling. Problems associated with this injury are scar formation, atrophy and contracture of the quadriceps, poor quality of remaining reabsorbed tendon, inadequate soft tissue, proximal patellar migration and prolonged post operative immobilization. Hence these injurie...

Objective The study aimed to investigate whether there is any association of anterior knee pain and knee function with chondromalacia stage and patellofemoral alignment in patients with anterior knee pain for over a month and with chondromalacia patellae (CMP) detected by magnetic resonance imaging (MRI). Materials and Methods We reviewed the medical records of 38 patients who underwent a kne...

BACKGROUND The aim of this study was to evaluate the patellar height and degenerative changes of the knee by radiographic assessment after patellar tendon reconstruction for chronic anterior cruciate ligament deficiency. METHODS This series included 44 patients (44 knees) with an average age of 31 years and an average follow up of 58 months. The central one third of the patellar bone-tendon-b...

We report the outcome of 32 patients (37 knees) who underwent hemicallostasis with a dynamic external fixator for osteoarthritis of the medial compartment of the knee. There were 16 men (19 knees) and 16 women (18 knees) with a mean age at operation of 54.6 years (27 to 72). The aim was to achieve a valgus overcorrection of 2° to 8° or mechanical axis at 62.5% (± 12.5%). At a mean follow-up of ...

Biomechanical studies have shown the use of suture anchors (SA) to be superior to the traditional transosseous sutures (TS) in the repair of quadriceps tendon rupture (QTR). This study aimed to analyze and compare the functional outcomes of patients treated for quadriceps tendon ruptures using suture anchors or transosseous sutures. Patients having undergone suture anchor repair or transosseous...
