Cruciate Retaining (CR) Total Knee Replacement Surgery
A Cruciate Retaining (CR) Total Knee Replacement Surgery is an advanced knee replacement surgery technique in which the posterior cruciate ligament (PCL) is preserved, provided it is healthy and functioning properly. By retaining the PCL, this type of total knee replacement surgery helps maintain more natural knee movement, better stability, improved balance, and enhanced proprioception (the body's ability to sense joint position). Patients often experience significant pain relief, improved mobility, and better long-term function after knee surgery.
During the knee replacement surgery, the orthopedic surgeon carefully evaluates the condition, strength, and balance of the PCL. If the ligament is found to be weak, damaged, or unable to provide sufficient stability, it is in the patient's best interest to convert to a Posterior Stabilized (PS) total knee replacement surgery. This decision is made during the procedure to ensure optimal knee stability, proper alignment, improved joint function, and long-lasting implant performance. The choice between a Cruciate Retaining (CR) and Posterior Stabilized (PS) implant is always personalized based on the patient's knee condition, with the primary goal of achieving the safest and most successful outcome.
Today, robotic knee replacement surgery has transformed the way knee surgery is performed. When combined with advanced robotic-assisted technology, both CR and PS knee replacement surgery procedures offer highly accurate implant positioning, precise soft-tissue balancing, improved joint alignment, reduced tissue damage, faster recovery, and excellent long-term outcomes. Robotic knee replacement surgery also enhances surgical precision, helping patients regain mobility more confidently while improving the overall success of total knee replacement surgery.
Whether a patient requires a Cruciate Retaining or Posterior Stabilized implant, the ultimate objective of every knee replacement surgery is to relieve pain, restore knee function, and help patients return to an active, comfortable lifestyle.
