Due to the pathoanatomical changes in hallux valgus feet, the plantar flexion moment of the first metatarsophalangeal joint is reduced. Therefore, load bearing of the hallux is decreased during push-off. We assessed loading parameters in hallux valgus feet. Based on dorsal-plantar weight bearing radiographs of 61 feet, the intermetatarsal-, hallux valgus-, distal metatarsal articulation-angle, ...

OBJECTIVE The purpose of this study was to compare the clinical outcomes between patients with a valgus or varus deformity undergoing minimally invasive total knee arthroplasty through the medial approach. METHODS The patients were classified into 2 groups according to the preoperative femorotibial angle measured on an anteroposterior long leg roentgenogram. The valgus group comprised of 26 k...

BACKGROUND The Cochrane review of hallux valgus surgery has disputed the scientific validity of hallux valgus research. Scoring systems and surrogate measures such as x-ray angles are commonly reported at just one year post operatively but these are of dubious relevance to the patient. In this study we extended the follow up to a minimum of 8 years and sought to address patient specific concern...

BACKGROUND There are no unified theories as to the anatomical changes that occur with hallux valgus, we investigated the radiological characteristics and anatomical risk factors for hallux valgus deformity in Chinese adults. METHODS We reviewed 141 patients with hallux valgus (206 feet; 15 males, 126 females; mean age, 58.5 years). These patients attended Peking University People's Hospital f...

Background: The maintenance of deformity in the ankle and hindfoot after correction of knee deformity following kneearthroplasty may cause abnormal tension in the knee and patient dissatisfaction. The aim of this study was to determinethe effect of knee arthroplasty on the hindfoot alignment in patients with severe genu varum and valgum.Methods: A total of 84 patients with pri...

BACKGROUND The amount of medial compartment opening for medial knee injuries determined by valgus stress radiography has not been well documented. The purpose of this study was to develop clinical guidelines for diagnosing medial knee injuries using valgus stress radiography. HYPOTHESIS Measurements of medial compartment gapping can accurately differentiate between normal and injured medial s...

Medial collateral ligament (MCL)injury, is one of the most common ligament injuries of the knee,mostly results from a valgus force.Restoration of function and going back to the pre-injury level of function is the aim of treatment in ligament injuries of the knee. There are multiple soft tissue structures in medial side that play an important role in connection with each other to retain medial s...

Introduction: The most common cause of ankle osteoarthritis (OA) is posttraumatic, with around 80% of all cases, followed by primary and secondary ankle OA. Patients often present wit asymmetric involvement of the tibiotalar joint, resulting in valgus or varus deformity of the ankle and hindfoot. The etiology of asymmetric arthritic ankles can be divided into 2 main etiologic and morphologic gr...

A total of 20 pairs of fresh-frozen cadaver femurs were assigned to four alignment groups consisting of relative varus (10 degrees and 20 degrees) and relative valgus (10 degrees and 20 degrees), 75 composite femurs of two neck geometries were also used. In both the cadaver and the composite femurs, placing the component in 20 degrees of valgus resulted in a significant increase in load to fail...

Results: The overall injury distribution was valgus–external rotation (32.9%), phantom foot (22.5%), hyperextension (19.0%), boot induced (7.8%), collision (2.2%), and other (15.6%). The phantom foot mechanism was most common in ages 30 to 40 years (36.3% of all injuries within this mechanism; P < .01). Children and adults showed no significant difference in distribution of injury mechanism. Of...
