Hi, thanks for writing to HCM.
The options for your problem are many depending upon your expectations and the condition of your soft tissues around the joint and extent of damage to the intra articular structures.
Now a days no body is accepting a knee fusion unless the joint is grossly damaged by infection.
* If you are an elderly person with very limited physical demands and you need a stable painless joint , then consider ARTHRODESIS
* If you are a middle aged person, then TOTAL KNEE REPLACEMENT
(TKR) is a better option. The prerequisite for TKR is that no infection should be present in the knee and the collateral ligaments of the joint should be intact.
So you need a detailed clinical evaluation to offer you a surgical procedure that gives you a reasonable range of movement to your knee joint.
Hope this information is helpful. Good day
