Outcome Measures

Primary Outcomes (2)

  • Pain intensity

    Change From Baseline in Maximal and minimal Pain on the 11-point Numeric rating score Pain Scale (NRS 0-11) ;Numeric 11-point rating score is widely accepted self-reported score for measurement of chronic and acute pain in researches.Possible scores range are between 0-free of pain and 10-the worst imaginable pain.

    Baseline ,1 hour,1 month, 3 month and 6 months

  • KOOS

    The Knee injury and osteoarthritis outcome(KOOS) score change in percentage from baseline and 1 month following adductor canal block \[ Time Frame: Baseline and 1 month following adductor canal block \] KOOS is valid,reliable outcome measure in patients with knee osteoarthritis. usually used following knee surgery.This method is recognised as useful also in other and nonsurgical knee treatment.Shortened version widely used in North America is western Ontario and McMaster Universities Index(WOMAC)

    Baseline ,1 hour,1 month, 3 month and 6 months

Secondary Outcomes (5)

  • Maximum voluntary isometric contraction of quadriceps muscle (MVIC)

    Baseline ,1 hour,1 month, 3 month and 6 months

  • Timed up to go test (TUG)

    Baseline ,1 hour,1 month, 3 month and 6 months

  • Satisfaction of patient

    Baseline ,1 hour,1 month, 3 month and 6 months

  • Range of knee motion (ROM)

    Baseline ,1 hour,1 month, 3 month and 6 months

  • 30 seconds stand up chair test (30 s SCT)

    Baseline ,1 hour,1 month, 3 month and 6 months

Study Arms (2)

Canal adductor blockade

After surgical cleaning of the anteromedial thigh, all participants in this group received single shot ultrasound guided canal adductor blockade with 14 ml 0,25% levobupivacaine and 100 mcg clonidine mixed in the same syringe. Investigators previously scanned the adductor canal and chose the middle of the canal as the entry point of the 10 cm echogenic ultrasound needle. After the blockade, all participants were monitored in our ambulance for the next hour.

Procedure: Canal adductor blockade

Pulsed radiofrequency therapy

After surgical cleaning of the anteromedial thigh, all participants in this group received ultrasound-guided pulsed radiofrequency therapy. Investigators previously scanned the adductor canal and chose the middle of the canal as the entry point of the RF 10 cm needle with a 1 cm free tip. After sensory and motor checking all patients have gotten 6 minutes of therapy divided into 3 sequences of 2 minutes of 50 V current and 42. Before starting the PRF therapy all participants have gotten 2 ml 0,25% levobupivacaine through the needle for preventing discomfort during the procedure. After the treatment, all participants were monitored in our ambulance for the next hour.

Procedure: Canal adductor pulsed radio-frequency therapy

Interventions

The same experienced anesthesiologist has performed all blocks. Always after surgical cleaning of the anteromedial thigh, all participants in this group received single shot ultrasound guided canal adductor blockade. After the blockade, all participants were monitored in our ambulance for the next hour.

Sampling MethodProbability Sample
Study Population

All participants included in this study were sent by family physicians to our Pain ambulance and all have already been diagnosed with knee osteoarthritis chronic pain. The diagnosis was confirmed by Orthopedist engaged in our study. Anesthesiologist decides if the patient is appropriate for the study.

You may qualify if:

  • Diagnose of the Knee osteoarthritis confirmed by orthopedic examination
  • K-L grades 3 and 4
  • A sufficient level of education to understand study procedures
  • Be able to communicate with site personnel
  • Age \>45 years

You may not qualify if:

  • Any cardiovascular, hepatic, or renal conditions that would compromise participation, in the opinion of the investigator
  • Severe neurologic conditions interfere with a knee condition
  • Narcotic dependent (opioid intake of more than 3 months and more than 30 mg of daily oral morphine equivalents)
  • Coexisting severe hematological disorder or deranged coagulation parameters
  • Psychiatric illnesses
  • Allergy to any of the drugs used in the study
  • Infection or malignancy at the site of the block
  • Any active systemic infection
  • Implanted electronic devices like spinal cord stimulators, cardiac pacemakers or similar
