Meniscal injuries are one of the most common intra-articular knee injuries. Different treatments are presented depending on the symptoms and duration of meniscus tears, such as arthroscopic partial meniscectomy, physiotherapy, or even pharmacological treatment. The purpose was to investigate the effect of a concentric isokinetic knee muscle strengthening program on strength, joint range of motion, physical performance, quality of life and pain tolerance in overweight/obese women with chronic meniscal lesions. Twenty-four overweight/obese women were randomized into two groups. A control group (CG) performed a usual rehabilitation program plus isokinetic muscle strengthening (IMS) in the continuous passive motion mode and measured with an isokinetic dynamometer. An experimental group (EG) performed the same program in combination with IMS in the isokinetic active mode. The peak torque of the knee extensors (PTE) and flexors (PTF), sit-to-stand test, stair climb test, joint amplitude, heel-to-buttock distance, Thessaly test, KOOS questionnaire of pain and quality of life were measured pre- and post-protocol. After the intervention, the sit–stand number for both groups was significantly higher (p < 0.001) and the time to climb stairs was significantly reduced for the EG (p < 0.001). A significant improvement in joint range of motion, life quality (p < 0.001), relief in knee pain (p < 0.001) and in the post-program evaluation at the EG (p < 0.05) was noted. There was no significant difference in PTE and PTF between groups at 60°/s and 180°/s. The IMS in the active mode could be an effective therapeutic modality in managing middle-aged patients suffering from a degenerative meniscal tear.

Around the world, chronic diseases have impacted the health and quality of life of many individuals. These chronic non-communicable diseases (NCDs), such as cancer, diabetes, cardiovascular disorders, and lung disease, are expensive to treat, frequently require lifelong care, and worsen drastically if treatment is postponed or of poor quality. This phenomenon will place pressure on healthcare systems to adjust to meet these evolving demands by creating efficient preventive strategies. One of the key epidemiological trends of the current times is the rise of chronic and degenerative diseases. This study will provide an overview of chronic diseases and helps to provide a more detailed image of pain and coping strategies. This requires adapting health systems and health policies and a shift from disease-centered to people-centered approaches and population health measures.
