Brief Summary

Genicular nerve block (GNB) is a novel and promising interventional method for pain in knee osteoarthritis (KOA). However ,it contains afferent fibers that receive impulses from proprioceptive and deep sensory receptors located in the joint capsule, ligaments, muscles, tendons and periosteum. These proprioceptive stimuli are effective on joint position and biomechanics, protect the joint from injuries and help maintain balance. This study aims to evaluate Pproprioception and static balance after ultrasound-guided GNB in patients with knee osteoarthritis.

Conditions

Osteoarthritis; Osteoarthritis, Knee; Proprioceptive Disorders; Balance; Distorted

Outcome Measures

Primary Outcomes (2)

• Visual analog scale (VAS)

  Ten-cm VAS was used as a self-report measure for knee joint pain. Turkish Validity and Reliability of scale was published. 0 indicates no pain and 10 indicates unbearable pain. As it approaches 10, the pain becomes more severe.

  24 hours

• HUR SmartBalance®: HUR SmartBalance®

  provides both balance assessments and rehabilitative training programs. Training programs are used in vertigo rehabilitation, balance training in mild gait disorders and fall prevention in elderly. Balance scores allow assessments and comparison in terms of static balance, proprioception disturbance, visual dependency and vestibular dominant proprioception . It consists of Balance Trainer, Support Rail, SmartBalance Software, Touchscreen Computer and Foam surface

Genicular blocks

OTHER

Genicular blocks were applied bilaterally by another physiatrist who was experienced in ultrasonographic (US) interventional procedures more than 5 years. Total of 6mL solution consisting of 0.5 mg/2mL dexamethazone and 4mL %1 lidocaine for three branches of genicular nerves (superomedial, superolateral and inferomedial branches) was divided into three branches for each knee. Total of 12 mL solution was applied for each patient. Antiseptic precautions were taken, sterile environment was prepared. A 5-12 MHz linear probe (Loqiq P5, GE Medical systems) was used for all US evaluations. The probe was positioned in line with the femur shaft. Firstly to find the superomedial genicular nerve, probe was moved to the junction of femur shaft and medial femoral condyle. Color doppler was used to clarify superomedial genicular artery and 2mL injection solution was applied around the pulsatile artery region.
