Geriatric care is a specialized field of medicine and healthcare focused on the unique health needs of older adults, generally defined as those 65 and older. This comprehensive approach addresses the physiological changes, complex conditions, and physical, functional, emotional, and social needs of the elderly, aiming to prevent illness, treat age-related diseases, maintain independence, and enhance their quality of life. Geriatric care is provided by geriatricians and geriatric nurses, who offer tailored support to help seniors age with dignity.

Spine surgery involves preparing for the operation by understanding patient expectations, optimizing health, and avoiding food/drink before surgery, and then focusing on post-operative care which includes managing pain with medication, gradually resuming activities as directed by doctors, wearing braces, participating in physical therapy to regain strength and mobility, and avoiding bending, lifting, or twisting to protect the surgical site and promote healing.

Knee injury pain can stem from injuries to the bones, ligaments, tendons, or cartilage, with common causes including ligament tears (like ACL), meniscus tears, tendinitis, bursitis, and patellofemoral syndrome. Other causes include fractures, dislocations, and arthritis.
