ABSTRACT

Background: Knee pain is a prevalent condition affecting individuals of all age groups, often resulting from injuries, arthritis, infections, gout, or repetitive strain. The knee joint, composed of bones, ligaments, tendons, and muscles, is essential for mobility and stability. Strengthening exercises and physical therapy play a critical role in enhancing knee joint function, reducing pain, and preventing further injury by improving biomechanical efficiency. Methodology: A total of 30 participants diagnosed with Grade 2 knee osteoarthritis were enrolled and randomly divided into two equal groups (n = 15). Pain and functional status were assessed using the Numeric Pain Rating Scale (NPRS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) before and after a four-week intervention. Group A performed Terminal KneeExtension (TKE) exercises with a tension band, while Group B performed Wall Sits (WS). Both groups followed a five-day-per-week regimen. Results: Both interventions yielded significant improvements in pain and functional scores (p < 0.05). Group A (TKE with tension band) showed superior effectiveness in pain reduction, whereas Group B (WS) demonstrated greater improvements in functional capacity. Despite these variations, overall performance between the two groups was found to be statistically comparable. Conclusion: The study concludes that both TKE with a tension band and wall sits are effective in managing knee osteoarthritis symptoms. TKE is more effective in pain relief, while wall sits offer greater functional enhancement. Keywords: Terminal knee extension (TKE), Wall sits, Osteoarthritis knee, closed kinetic chain (CKC) exercises
