Primary Outcome Measures:
  • Proprioceptive acuity in Knee Joint. Proprioceptive acuity (difference between the knee angles at the target and reproduced positions) was assessed by active repositioning of the lower limb after injection or no injection. [ Time Frame: within one hour after intervention ]

Enrollment: 40
Study Start Date: May 2009
Study Completion Date: January 2010
Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Infusion
20cc saline infusion into the knee joint
Procedure: Normal saline
20 cc normal saline injection into the knee joint
No Intervention: No infusion Procedure: Normal saline
20 cc normal saline injection into the knee joint

Detailed Description:

Proprioception is a sensory modality that provides feedback on the internal status of the body and enables us to perceive joint position and motion.

Osteoarthritis (OA), also called degenerative joint disease, is a major musculoskeletal condition characterized by loss of articular cartilage that leads to pain and loss of function. The most commonly affected joint is the knee, and OA may result in changes that affect not only intracapsular tissues, but also periarticular tissues, such as ligaments, capsules, tendons, and muscles. Many studies have examined the proprioceptive status of knee OA, and subjects with knee OA are known to have impaired proprioception compared with age-matched controls.

Joint effusion is a common symptom associated with chronic degenerative joint condition, but the effects of effusion on knee joint proprioception have not been investigated in detail.

A volume of 20 mL of normal saline was injected into the knee joint cavity of subjects in the experimental group under ultrasonographic guidance. Proprioceptive acuity was assessed by active repositioning of the lower limb using an electrogoniometer to measure knee joint position sense (JPS) under both non-weight-bearing and weight-bearing conditions twice, with a 20-min rest interval.
