A prosthetic knee joint is an artificial knee replacement that is used to replace a damaged or diseased knee joint. It is designed to mimic the natural movement and function of a real knee joint, allowing individuals to walk and perform other activities with greater ease and comfort. Prosthetic knee joints come in various types, including total knee replacement (TKR) and partial knee replacement (PKR). In a TKR, the entire knee joint is replaced with an artificial implant, while in a PKR, only the damaged or diseased portion of the knee is replaced. The materials used in prosthetic knee joints are typically made of metal, plastic, or ceramic components, and are designed to be durable and long-lasting. The success of the surgery and the longevity of the implant depends on several factors, such as the patient's age, weight, and overall health, as well as the skill of the surgeon performing the procedure. Physical therapy and rehabilitation are often necessary after a prosthetic knee joint surgery to help the patient regain strength and mobility in the affected leg.

KNOW YOUR ACTIVITY LEVEL : Level One(K1) The patient has the ability or potential to use a prosthesis for transfers or ambulation on level surfaces at fixed cadence. This is typical of a household ambulator or a person who only walks about in their own home. Level Two(K2) The patient has the ability or potential for ambulation with the ability to traverse lowlevel environmental barriers such as curbs, stairs or uneven surfaces. This is typical of the limited community ambulator. Level Three(K3) The patient has the ability or potential for ambulation with variable cadence. A person at level 3 is typically a community ambulator who also has the ability to traverse most environmental barriers and may have vocational, therapeutic or exercise activity that demands prosthetic use beyond simple locomotion. Level Four(K4) The patient has the ability or potential for prosthetic ambulation that exceeds basic ambulation skills, exhibiting high impact, stress or energy levels. This is typical of the prosthetic demands of the child, active adult or athlete.
