Healthy knee kinematics during dynamic full flexion were evaluated using 3D-to-2D model registration techniques. Continuous knee motions were recorded during full flexion in a lunge from 85° to 150°. Medial and lateral tibiofemoral contacts and femoral internal-external and varus-valgus rotations were analyzed as a function of knee flexion angle. The medial tibiofemoral contact translated anter...

A prospective study was performed on 24 patients to evaluate the early results of our experience with minimally invasive distal metatarsal osteotomy to treat mild-to-moderate hallux valgus deformities in adults. After failure of conservative treatment and persistence of footwear-related pain, a percutaneous distal first metatarsal osteotomy was performed, stabilized by a Kirschner wire, followe...

We performed a randomised, prospective study of 80 mobile-bearing total knee arthroplasties (80 knees) in order to measure the effects of varus-valgus laxity and balance on the range of movement (ROM) one year after operation. Forty knees had a posterior-cruciate-ligament (PCL)-retaining prosthesis and the other 40 a PCL-sacrificing prosthesis. In the balanced group (69 knees) in which the diff...

A multi-centre clinical trial of ICLH (Freeman-Swanson) arthroplasty has been in progress since 1971. In this paper the results up to two years after operation are reported in seventy-one knees displaying at least 30 degrees of fixed flexion, 25 degrees of valgus or 20 degrees of varus, before operation. It has been found that knees displaying 70 degrees of fixed flexion, 70 degrees of valgus, ...

Objective: Presentation of clinical and radiological outcome of a case series of scarf osteotomy. Patients and Methods: The study involved 20 patients with 24 feet affected with symptomatic moderate to severe hallux valgus. Clinical assessment was done using American Orthopedic Foot and Ankle Society (AOFAS) score. Radiological assessment utilized measurement of hallux valgus angle (HVA), inter...

We report a prospective case-controlled study which compared the outcome of knee replacement in seriously deformed and slightly deformed knees. There were 51 knees with varus or valgus deformity greater than 20 degrees matched for age, gender, disease, type of prosthesis and time of operation with a control group in which the alignment of the leg was within 5 degrees of normal. The clinical out...

Hallux valgus deformity combined with dorsal dislocation of the second metatarsophalangeal joint is frequently observed in rheumatoid arthritis cases. However, hallux valgus deformity without lesser toe dislocation is also seen in rheumatoid cases. Dislocated second toe cause the loss of the lateral support on the hallux, suggesting the importance to confirm the state of lesser toe MTP joint wh...

Nondriving intersegmental knee moment components (i.e., varus/valgus and internal/external axial moments) are thought to be primarily responsible for the etiology of overuse knee injuries such as patellofermoral pain syndrome in cycling because of their relationship to muscular imbalances. However the relationship between these moments and muscle activity has not been studied. Thus the four pri...

Female athletes are substantially more susceptible than males to suffer acute non-contact anterior cruciate ligament injury. A limited number of studies have identified possible biomechanical risk factors that differ between genders. The effect of fatigue on the biomechanics of landing has also been inadequately investigated. The objective of the study was to examine the effect of gender and fa...
