Description
Aim: Comparison of the Therapeutic Efficacy of TENS vs Ultrasound-guided Genicular Nerve Block in Patients with Knee Osteoarthritis. Methods: Total 50 patients were included in this study, 25 each in the TENS group and GNB group, respectively. Primary OA knee, Radiologic K/L (Kellgren-Lawrence Grading Scale) score: 3 and 4, Age: 40–80 years, poorly responding to initial treatments, Patients unwilling or contraindicated for surgical management and Visual acuity scale (VAS) >5 were included in this study. All the subjects recruited in our study underwent some baseline routine blood investigation. The total study population (n = 50) was divided into two groups (25 in each group) randomly. Before starting treatment, basic information like age, sex, and duration of disease were noted and baseline VAS and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were calculated. A short course of acetaminophen tablet, lifestyle modification, and therapeutic exercise regimen was prescribed and followed. Results: All numerical variables were found to be normally distributed by Kolmogorov–Smirnoff goodness-of-fit. The mean age of patients in TENS group (n = 25) was around 54.26 (±7.68) years and in GNB group (n = 25) was 55.63 (±6.97) years. a comparison of the numerical variable VAS for pain between both the groups by Student’s unpaired “t” test shows, after continuous 3 weeks of daily TENS therapy, knee pain improved from a mean VAS of 7.35 (±0.81) at baseline to 3.66 (±1.14) at the end of 1 month. Whereas, with a single sitting of GNB, the mean VAS improved from a baseline value of 7.41 (±0.86) to 2.87 (±0.92) at the end of 1 month. Thus, GNB shows a significantly better result (p < 0.05) in improving knee pain than TENS therapy at 1 month. Although at the end of 3 months, the VAS in both the groups again becomes comparable (p = 0.21). In the TENS group, WOMAC improved from a mean of 47.23 (±6.10) at baseline to 27.44 (±5.87) at the end of 1 month. In the GNB group (group II), the mean WOMAC improved from a baseline value of 46.69 (±5.85) to 24.44 (±4.81) at the end of 1 month. Thus, similar to pain, GNB shows significant better result (p < 0.05) in improving knee stiffness and function than TENS therapy at 1 month. At the end of 3 months, the WOMAC in both the groups again becomes comparable (p = 0.82.). Conclusion: We concluded that GNB is a better choice than TENS in the short-term and comparable in the long term and both add to the OA knee rehabilitation program significantly.
