BACKGROUND This study aims to explore the technique of soft tissue balance and joint tension maintenance in total knee arthroplasty (TKA) for the rheumatoid arthritis (RA) patients with flexion contracture of the knee. METHODS This retrospective study reviewed flexion contracture deformity of RA patients who underwent primary TKA and ligament and soft tissue balancing. Based on the flexion co...

Accurate rotation of the femoral component in total knee arthroplasty is important for normal patella tracking, symmetrical patellofemoral joint contact, neutral varus-valgus positioning in flexion, correct rotational alignment of the tibia in extension and the avoidance of anterior femoral notching . Internal rotation of the femoral component causes a shift into valgus alignment with flexion a...

Reliability theory is used to assess the sensitivity of a passive flexion and active flexion of the human lower leg Finite Element (FE) models with Total Knee Replacement (TKR) to the variability in the input parameters of the respective FE models. The sensitivity of the active flexion simulating the stair ascent of the human lower leg FE model with TKR was presented before in [1,2] whereas now...

BACKGROUND Hemophiliacs have extrinsic tightness from quadriceps and flexion contractures. We sought to examine the effect of a focused physical therapy regimen geared to hemophilic total knee arthroplasty. METHODS Twenty-four knees undergoing intensive hemophiliac-specific physical therapy after total knee arthroplasty, at an average age of 46 years, were followed to an average 50 months. ...

Electromyographic activity of the erector spinae was studied in 25 healthy, young individuals during forward bending and then coming back to erect posture. Sudden onset of electrical silence called the flexion-relaxation phenomenon was seen to occur in all at 57% of the maximum hip flexion and at 84% of the maximum vertebral flexion. Abrupt re-commencement of the activity was seen at almost sim...

Flexor pronator muscles (FPMs) play a key role in stabilizing the elbow joint against valgus forces. However, no studies have investigated the in vivo kinematics of FPMs against these forces on the elbow. This study aimed to clarify the in vivo contribution of each FPM as a dynamic stabilizer in a clinical situation.Twelve healthy volunteers participated in this study. Verbal informed consent w...

purpose: the purpose of this study was to investigate the effect of kinesio-taping on the range of motion of cervical lateral flexion point in subjects with trigger point in upper trapezius muscle. methods: a total of 32 subjects with myofascial trigger point in upper trapezius participated in this randomized controlled trial (rct). the subjects were randomly assigned to two groups: kinesio-tap...

background: low back pain (lbp) is the second most common medical complaint. it’s estimated that about 70-85% of the population will suffer at least one episode of lbp during their life. the aim of present study was to compare the effects of massage and modality in patient with sub-acute and chronic non-specific lbp methods: in this clinical trial study 30 women (meanage: 33.96±10.93) with sub-...

BACKGROUND There have been several reports that partial ulnar transfer (PUNT) is preferable for reconstructing elbow flexion in patients with upper brachial plexus injuries (BPIs) compared with intercostal nerve transfer (ICNT). The purpose of this study was to compare the recovery of elbow flexion between patients subjected to PUNT and patients subjected to ICNT. METHODS Sixteen patients (13...
