Why is the ACL removed in total knee replacement?
The goal of TKA is to approximate the function of a normal knee. The retention of the ACL allows for better knee, kinematics, improved proprioception, increased maximum flexion and an overall improvement in the knee function.
Are ligaments cut during total knee replacement?
In traditional knee replacement surgery, the surgeon makes a long incision over the middle of the knee and cuts muscles, tendons and ligaments to get to the knee joint.
What muscles tendons ligaments are cut during total knee replacement?
The standard approach to knee replacement involves cutting the quadriceps tendon. If the quadriceps tendon is cut, patients typically need walking aids for 3 to 6 weeks to allow this cut to heal. Also, cutting the quadriceps causes more pain and delays the recovery from the operation.
Is the bursa removed during knee replacement?
As the bursa could be decompressed entirely from an anterior midline incision, it was decided by the surgeon that the bursa would be removed at the same time as the total knee arthroplasty.
What is removed during a total knee replacement?

Is the patella removed in total knee replacement surgery?
This procedure is a patella (knee cap) replacement. It involves removing a portion of the front of the lower end of the femur. This is the surface that contacts the underside of the patella. The underside of the patella is then shaved off and is fitted with a polymer plastic implant.
Is the meniscus removed during total knee replacement?
With this type of tear, surgical intervention is usually necessary to trim the torn areas. An orthopedic surgeon will use arthroscopy to cut out the meniscus’ torn section if surgery is indicated. However, this surgery may not completely eliminate the pain, catching, and clicking symptoms.
What is cut during knee replacement?
Traditional total knee replacement entails cutting into the quadriceps tendon, which connects the large quadriceps muscle group on the front of the thigh to the kneecap. The surgeon then moves the kneecap out of the way to access the arthritic joint.
Can you get tendonitis after knee replacement?
An estimated 20% of patients with total knee arthroplasty will report pain following the procedure. Careful examination of the structures around the knee can reveal tendonitis, bursitis, and soft tissue pain that respond to usual care.
