Aim: To determine and compare the effects of static and proprioceptive neuromuscular facilitation (PNF) hamstring stretching exercises on hamstring flexibility, pain, functional status, and dynamic balance in patients with knee osteoarthritis (KOA). Materials and Methods: A total of 36 symptomatic patients with KOA were randomly assigned to two groups as Static Hamstring Stretching (SHS; n=18) and PNF-Hamstring Stretching (PNF-HS; n=18) and exercises were applied in addition to a standard physiotherapy program consisting of Hot-pack, Ultrasound and TENS for 12 weeks. Outcomes were evaluated with Visual Pain Scale (VAS), Active Knee Extension Test (AKET), The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Timed Up and Go (TUG) test. Results: Both stretching exercises statistically improved knee pain, AKET, WOMAC scores (p
