Introduction: Suprapatellar (SP)-nailing versus infrapatellar (IP)-nailing for distal shaft tibia fractures and post-operative complications like anterior knee pain sequelae such as malalignment, retropatellar chondropathy infection, well physical functioning quality of life were the primary objectives this study.Methods: Department Orthopaedics is conducting a study on topic. Group A (16 cases...

We describe the radiographic measurement of the angle of tilt of the patella and relate it to malalignment of the extensor mechanism. The tilt angle is defined as the angle subtended by a line joining the medial and lateral edges of the patella and the horizontal. The radiograph (Merchant type) is taken with the foot pointing up, the lower edge of the film parallel to the ground, and the knee a...

BACKGROUND Successful total knee replacement (TKR) requires accurate component placement and coronal plane malalignment of greater than 3o varus/valgus from the mechanical axis has been shown to predispose to early failure.1–3 An extramedullary alignment jig is most commonly used to identify the mechanical axis. The distal end of the jig should be centred over the ankle mortise, which can be di...

This case report describes a rare case of recurrent dislocation of the patella which was accompanied with trochlear dysplasia and malalignment of the patella in a 15-year-old girl. She complained of hemoarthrosis and recurrent patellar dislocation in the early knee flexion phase. Plain radiography and computed tomography (CT) showed patellar malalignment (quadriceps angle 20°) and severe dyspla...

The goal of computer-assisted navigation (CAN) is to increase surgical accuracy and reduce the chance of malposition of implants. For total knee arthroplasty (TKA), malalignment is commonly defined as a variation of greater than 3° from the targeted position. Proper implant alignment is believed to be an important factor for minimizing long-term wear, risk of osteolysis, and loosening of the pr...

OBJECTIVE To investigate the association between knee pain during gait and 4 clinical phenotypes based on static varus alignment and varus thrust in patients with medial knee osteoarthritis (OA). METHODS Patients in an orthopedic clinic (n = 266) diagnosed as having knee OA (Kellgren/Lawrence [K/L] grade ≥1) were divided into 4 phenotype groups according to the presence or absence of static v...

In relation to your comment, I fully agree that the routine use of magnetic resonance imaging in the study of anterior knee pain can increase the expenditure of healthcare systems. Nevertheless, the article does not aim to establish the use of magnetic resonance imaging as a dogma or guideline; rather, the intention is to assess the usefulness of this test in the diagnosis of patellar malalignm...

Navigated total knee arthroplasty (TKA) is promoted as a means to improve limb and prosthesis alignment. This study involved a systematic review and meta-analysis for all randomized controlled trials in the literature from 1986 to 2009 comparing alignment outcomes between navigated and conventional TKA. Alignment outcomes were pooled using a random-effects model, and heterogeneity was explored....
