OBJECTIVES To examine the genetic contribution to common, apparently sporadic, radiographic knee chondrocalcinosis (CC) and pyrophosphate arthropathy (PA). METHOD (1). DESIGN radiographic sibling study. Comparison of the prevalences of knee CC and PA in siblings of index cases with PA with those in the community. (2). SUBJECTS 80 index cases with PA listed for total knee replacement; 122 ...
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 ...
Background and Objective: Muscle weaknesse particularly in association with quadriceps muscle is known as a risk factor in the development and progression of knee osteoarthritis (KOA). The objective of this study was to compare quadriceps muscle strength (QMS) between asymptomatic controls and KOA patients and to elucidate its relationship with knee pain and radiographic changes. Materials a...
Background: There are not many reports regarding the treatment approaches of congenital dislocation of the knee in the literature. Therefore, the preferred method of treatment of this rare congenital disease is still controversial. Hereby, we report the treatment outcome of 29 patients admitted in Shafa Yahyaian Hospital during 40 years. Methods: In this retrospective study done in Shafa Yahya...
The purpose of current study was to investigate the spatio-temporal gait parameters and knee varus angle during walking at different speeds in young with knee varus. 18 subjects with varus deformity classified at grade 3 of bowleg and 17 healthy subjects, volunteered to participate in this study. The following variables include stance, swing, double support and cycle time, cadence, stride le...
In this report we describe a 78-year-old man whose total knee arthroplasty showed the symptoms of infection with brucella with radiographic signs of loosening 5 years after the index surgery. The patient was treated successfully after a 2-stage revision arthroplasty surgery along with using rifampicin and doxycycline for 8 weeks.
Objective Osteoarthritis is a degenerative disease of joints that causes degeneration and corrosion of joint surface. Because of osteoarthritis, the smooth and even movemvement of joints get interrupted. Osteoarthritis is the most common kind of arthritis and its prevalence is 19.3% in Iran. Patients with knee osteoarthritis usually have geno varum and hyperpronation of foot. The...
For prosthesis users, knee units can range from simple devices costing $2000 up to $45,000 for high-end, microprocessor-controlled systems. These higher-end electronic knees provide significant advantages in stability, gait, and metabolic rate compared their passive or mechanical counterparts. However, the high cost of such systems makes them inaccessible most amputees. In this study, it was hy...
BACKGROUND Arthrofibrosis is a postoperative complication of intra-articular knee surgery that can be difficult to treat. Evidence suggests that maximizing knee range of motion may improve outcomes in patients with arthrofibrosis who undergo arthroscopic debridement. HYPOTHESIS Patients who achieve greater knee range of motion will have better subjective scores. STUDY DESIGN Retrospective c...
BACKGROUND Football puts athletes at risk for knee injuries such meniscus and anterior cruciate ligament (ACL) tears, which are associated with the development of osteoarthritis (OA). Previous knee surgery, player position, and body mass index (BMI) may be associated with knee OA. HYPOTHESIS In elite football players undergoing knee magnetic resonance imaging at the National Football League's...
