objectives: skeletal-muscular disorders affect the biomechanics of the human body, especially the lower extremity, with a negative effect on the biomechanics of exercise. the main aim of this study was to evaluate the effect of fatigue on the kinematic variables of knee joints during countermovement jumps in female students of physical education with valgus knee deformity.  methods: fifteen sub...

The goal of arthroscopic partial meniscectomy is to preserve a stable rim of meniscal cartilage, removing only unstable, diseased tissue. As one of the most common orthopedic procedures performed in the United States, arthroscopic partial meniscectomy developed as an alternative to open total meniscectomy that leads to degenerative changes in the knee over time. The short-term results of this m...

Two-stage revision in infected knee arthroplasty is standard practice. One problem during the interim period is soft tissue fibrosis. Attempts have been made to preserve leg length and ligament length by introducing spacers, usually made out of antibiotic-loaded bone cement. We present a new interim prosthesis, which is made intra-operatively out of polymethylmethacrylate (PMMA). Antibiotic-loa...

Aims: Research has shown that most of the elderly suffer from knee osteoarthritis. Massage therapy is one of the non-pharmacological methods that according to studies can be used to relieve the symptoms caused by knee osteoarthritis in the elderly. Therefore, the present study was conducted with the aim of reaching a comprehensive view on massage therapy in relieving the symptoms of knee osteoa...

experiments wee performed to evaluate the contralateral effect of adjuvant induced mono arthritis. in these experiments laser doppler imaging (ldi) was used to investigate changes in blood flow. adjuvant was applied to induce chronic inflammation. temperature and knee diameter increased in the first week after administration in the administrated knee joint.substance p (sp) (a neruokinin with a ...

objective : the aim of this study was to validate the well-recognized outcome measure instruments (medical outcome study short form-sf-36, western ontario and mcmaster university osteoarthritis index-womac, mcmaster toronto arthritis patient preference disability questionnaire -mactar) for patients who had undergone total knee arthroplasty in iran, with its cultural and ethnic differences and c...

Most state-of-the-art bipedal robots are designed to be anthropomorphic, and therefore possess articulated legs with knees. Whilst this facilitates smoother, human-like locomotion, there implementation issues that make walking straight difficult. Many have move a constant bend in the avoid singularity occurring at knee joints. The actuators must constantly work maintain stance, which can result...

osteoarthritis (oa) a common disease of aged population and one of the leading causes of disability. incidence of knee oa is rising by increasing average age of general population. age, weight, trauma to joint due to repetiting movements in particular squatting and kneeling are common risk factors of knee oa. several factors including cytokines, leptin, and mechanical forces are pathogenic fact...
