, What is the pathophysiology of osteoarthritis? - 🧠 ANSWER ✔✔when
cartilage becomes damaged it starts to lose elasticity, making it more
susceptible to injury. With increasing stress and wear the bone starts to
become affected causing thickening of bone and formation of bone spurs
and osteophytes. Abnormal bone formations can break loose with cartilage
fragments and float within joint space. Debris cause synovium to mount
and inflammatory response to break down cartilaginous debris.

increase? - 🧠 ANSWER ✔✔the breakdown of remaining healthy cartilage,
leading to further degeneration
Osteoarthritis symptoms: - 🧠 ANSWER ✔✔pain that is exacerbated with
activity and better with rest (early dz), stiffness, swelling, pain and stiffness
