Effectiveness of Muscle Energy Technique on Patellofemoral Osteoarthritis: A Systematic Review

Paturu Swathi, Sindhura K Prasanth

Abstract: Significant functional restrictions result from patellofemoral osteoarthritis (PFOA), a prevalent degenerative disorder of the knee joint that is characterised by anterior knee discomfort, stiffness, and decreased mobility. Pharmacological, surgical, and physiotherapeutic procedures are all part of conventional management. Muscle Energy approach (MET) is a popular physiotherapy approach that uses active muscle contractions against controlled resistance to improve flexibility, alleviate discomfort, and restore joint mechanics. to assess how well Muscle Energy Technique (MET) works for people with patellofemoral osteoarthritis in terms of pain relief, range of motion, and functional performance. In accordance with PRISMA criteria, 100 papers that examined the impact of manual therapy and MET treatments on knee osteoarthritis that were published between 2008 and 2025 were analysed in a systematic review. Studies included randomized controlled trials, pre?post interventional designs, and systematic reviews. Databases were searched using keywords such as "Muscle Energy Technique", "patellofemoral osteoarthritis", "manual therapy", "quadriceps strengthening", and "pain reduction." MET also increased knee range of motion and hamstring flexibility, thereby improving joint biomechanics. When combined with quadriceps strengthening and patellar mobilization, MET yielded superior clinical outcomes compared to isolated strengthening or stretching exercises. The evidence indicates MET as a safe, non-invasive, and effective conservative approach for managing PFOA symptoms. Muscle Energy Technique is an effective manual therapy intervention for patients with patellofemoral osteoarthritis. It significantly reduces pain, increases flexibility, and improves knee joint function. Incorporating MET with strengthening and mobilization exercises provides a comprehensive, low-risk, and cost-effective physiotherapy approach. Further large-scale randomized controlled trials are recommended to standardize treatment parameters and validate the long-term benefits of MET in PFOA rehabilitation.
