When should I consider knee replacement surgery?

When your xray shows bone on bone changes, this means that the cartilage covering the ends of your bones in your knee is damaged and worn out. The underlying bone is exposed. If the cartilage is worn out on both bones in your knee, the result is bone on bone changes. This generally results in pain and swelling and instability when you walk. If your activities of daily living are affected, or you experience pain at night and you start limiting your activities because of pain, you should consider knee replacement surgery.

Where is the incision made for  knee replacement surgery?
​The implant can be inserted several ways. The incision may be made in the middle of the knee, the most common way or on either side of the kneecap. The advantage of making an incision on the side of the knee is that the muscles are not cut. However, the incision on the outer side of the knee has some disadvantages; certain knee implants cannot be easily used; the knee may be feel unstable. ie slips out when you walk and seeing the entire knee is more difficult. Choosing which side to make the incision is a conversation to have with your surgeon.
