Background: Chondromalacia patella is the most common cause of mechanical knee pain in young women. Q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. Objective: To identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and Q angle with age at onset of disease. Methods: All pa...

Purpose: Given the high prevalence of varus malalignment of the knee and the consequences of walking on different surfaces on this malalignment, the aim of the present study was to investigate the effect of walking inclination on knee angle in the frontal plane of patients with varus malalignment. Methods: 18 male subjects with varus malalignment classified at grade 3 bowleg, within the a...

Background Knee malalignment and variations in foot posture and function affect the forces transmitted through the knee joint and are associated with knee pain and medial tibiofemoral cartilage damage [1]. However, it is unclear whether altered foot posture and function are a compensatory mechanism to accommodate knee malalignment. Therefore, this study investigated changes in foot posture and ...

Malalignment is associated with an increased rate of loosening of knee prostheses. We present a case of primary knee replacement failure due to pre-existing tibial deformity. Correction of the deformity and associated malalignment was undertaken using the Ilizarov osteotomy method prior to full knee revision surgery.

The treatment of combined knee pathology is a challenging problem that requires careful attention to all aspects of the underlying disease. This is true of the interplay among malalignment and meniscal or articular cartilage restoration in the knee. Optimal outcomes are contingent on a comprehensive preoperative evaluation of patient-specific factors (patient expectations, patient age, and acti...

[Purpose] We evaluated the relationship between knee alignment and the electromyographic (EMG) activity of the vastus medialis (VM) to the vastus lateralis (VL) muscles in patients with knee osteoarthritis (OA) in a cross-sectional study. [Subjects and Methods] Forty subjects with knee OA were assessed by anatomic radiographic knee alignment and the VM/VL ratio was calculated. Surface EMG from ...

The progression of gonarthrosis results in reduction of physical activity. One of the factors that increase the risk of osteoarthrosis may be joint overload related to the malalignment of the mechanical axis of the lower extremity. The medial compartment (MC) of the knee is particularly susceptible to overload due to the external knee adduction moment (EKAM). Varus knee malalignment contributes...

OBJECTIVE To investigate in which way body mass index (BMI) and alignment affect the risk for knee osteoarthritis (OA) progression. METHODS Radiographs of 181 knees from 155 patients (85% female, mean age 60 years) with radiographic signs of OA were analyzed at baseline and after 6 years. Progression was defined as 1-point increase in joint space narrowing score in the medial or lateral tibio...

Lower limb alignment is an important contributing factor to the development of knee arthritis, and it is related to the articular cartilage wear pattern (1). Osteotomies around the knee are a well-recognized treatment for symptomatic unicompartmental knee arthritis associated to lower limb malalignment in young and active patients, with the attempt to preserve the native knee joint and delay kn...
