NCT06712394

Brief Summary

Interspace between the Popliteal Artery and Capsule of the posterior Knee (IPACK) block involves ultrasound-guided local anesthetic infiltration of the space between the popliteal artery and the posterior knee joint capsule. The purpose of the study; To investigate the effectiveness of this block applied to knee osteoarthritis in clinical practice. In this study, patients who underwent IPACK block by the practitioner; Demographic data, medications used, block success, block characteristics and block-related complications will be recorded observationally. Before and after the block procedure, patients' pain was measured with the Numeric Rating Scale (NRS) at 1st and 3rd months, their disability levels were measured with The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire and Short Form-12 (Short Form). Quality of life will be measured with the -SF-12) survey.

Outcome Measures

Primary Outcomes (2)

  • Pain assessment

    The Numeric Rating Scale (NRS) is a frequently used tool for assessing and monitoring the severity of pain. The pain scale measures on an 11-point rating system, where 0 indicates the absence of pain and 10 represents the most severe pain one can imagine. Patients are requested to assess their pain on a scale ranging from 0 to 10. The physician obtained from measurements at each visit by directly questioning the patient.

    1st and 3rd month after the procedure

  • Functional status

    The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of knee osteoarthritis. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: pain, stiffness, and physical function. The questionnaire evaluates activities of daily living and functional mobility. The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for pain, 0-8 for stiffness, and 0-68 for physical function. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.
