We observed a 75.9% increase in joint space width with SKETS therapy at the end of 3–4 weeks after starting therapy. The study by Jain et al. (2021) reports the mean medial and lateral joint space width of healthy Indian adult knee joints to be 5.34 (1.26) mm and 5.21 (1.04) mm respectively on the left side, and similar JSW measurements on the right side. In our study, the mean (SD) joint space width was narrowed to 2.57 (0.83) mm in joints affected with OA. This width increased (p < 0.001) by 1.77 (1.31) mm to 4.34 (1.59) at the end of 3-week therapy. Thus, SKETS therapy was able to regenerate cartilage repair and increase JSW to near normal.
SKETS therapy significantly improved (p < 0.001) the cartilage damage in 77.6% (132/170) joints at the end of therapy. Also, there was significant improvement in the composite symptom scores (sum of scores for joint pain, swelling, stiffness and tenderness)
