What happens to the patella in a total knee replacement?
Your surgeon makes a cut down the front of your knee to expose your kneecap. This is then moved to the side so the surgeon can get to the knee joint behind it. The damaged ends of your thigh bone and shin bone are cut away. The ends are precisely measured and shaped to fit the prosthetic replacement.
How do you fix malalignment of the patella?
Patellar tape and braces are designed to realign the patella within the femoral trochlea . This improves realignment and quadriceps function. Taping across an overly powerfull vastus lateralis can diminish its pull and so stimulate realignment. Another goal of taping is to pull the patella away from a painful area.
What are the signs of a failed knee replacement?
What are the signs of knee replacement failure? The most common symptoms of a failed knee implant are pain, decrease in joint function, knee instability, and swelling or stiffness in the knee joint.
Why does my kneecap hurt after total knee replacement?
Any increase in pain after knee replacement should raise concerns for infection. Most often, the signs of infection are obvious, but subtle infections may be the cause of persistent discomfort. 3 Patellofemoral (kneecap) problems: Kneecap problems are a common cause of knee replacement pain.
How often does patellar dislocation occur after total knee replacement?
The reported incidence of patellar problems after total knee replacement has ranged from 5 to 30 per cent. Patellar dislocation is infrequent but can cause disabling symptoms.
Is the patella always resurface in total knee arthroplasty?
Currently, there are 3 surgical approaches to the patella during primary total knee arthroplasty: always resurface, never resurface, or selectively resurface based upon patient factors such as quality of the articular cartilage and patellofemoral congruence at the time of surgery.
How to prevent patellar maltracking in total knee arthroplasty?
Several factors are crucial to prevent patellar maltracking in TKA: the use of an anatomical femoral component, a meticulous surgical technique, careful dynamic intraoperative assessment of patellar tracking, and, if necessary, the achievement of an adequate lateral release.

Are there any complications after total knee arthroplasty?
Patellar complications are a source of poor total knee arthroplasty (TKA) outcomes that can require re-operation or prosthetic revision. Complications can occur with or without patellar resurfacing. The objective of this work is to answer six questions.
