Minimally Invasive Knee Replacement: Benefits and Recovery

Minimally Invasive Total Knee Replacement Surgery overcomes the potential drawbacks of conventional knee replacement surgeries.

Knee replacement surgery can help older adults who have severe knee pain or arthritis. However, many patients worry about the surgery. They may wonder if they will be able to walk without pain after surgery, whether the pain will come back, and how long recovery will take. They may also be concerned about regular doctor visits and physiotherapy during recovery.

Minimally invasive total knee replacement surgery is designed to reduce some of these concerns. It uses a smaller surgical approach and aims to cause less damage to the surrounding tissues. This may help support recovery and improve the overall surgical experience.

Why Is Minimally Invasive Knee Replacement Considered Less Painful?

Knee replacement surgery can cause some discomfort during the early stages of recovery. Pain management is therefore an important part of the procedure. Traditionally, epidural anesthesia may be used to reduce pain during and after surgery. However, it can temporarily cause numbness and weakness in the legs, which may delay walking until the effect wears off.

With minimally invasive total knee replacement surgery, an adductor canal block may be used as part of the pain management plan. The adductor canal is a passage in the thigh that contains important nerves and blood vessels. A local anesthetic is injected into this area to reduce pain signals from the knee and lower leg.

Because the effect of a local anesthetic can wear off sooner than an epidural, some patients may experience less numbness and be able to begin walking earlier after surgery. Pain levels can vary from person to person, but appropriate pain management can make the early recovery period more comfortable.

Minimally Invasive Knee Replacement: Minimal Stitches and No Muscle Cutting

Minimally invasive total knee replacement surgery uses a surgical approach designed to reduce damage to the surrounding tissues. One technique is the subvastus approach, in which the quadriceps muscle is moved aside rather than cut to access the knee joint.

In a traditional knee replacement approach, a larger incision may be made over the knee, and the quadriceps muscle may be divided to reach the joint. The muscle is then repaired after the replacement is completed, which can contribute to the recovery process.

With the subvastus approach, the quadriceps muscle is moved to the side to provide access to the knee joint without cutting through the muscle. After the knee replacement is completed, the muscle is returned to its original position.

Because the muscle is preserved, this approach may help support earlier movement and recovery in suitable patients. However, the incision size, surgical approach, and recovery time can vary depending on the patient’s condition and the surgeon’s technique.

Recovery After Minimally Invasive Knee Replacement

Recovery after minimally invasive total knee replacement surgery can vary from patient to patient depending on overall health, age, fitness, and other factors. Some patients may be able to start walking with assistance within a few hours after surgery, depending on their condition and the surgeon’s advice.

As recovery progresses, patients may gradually become more independent with activities such as walking and using the bathroom. Physiotherapy and regular exercises are important to help improve knee movement, strength, and mobility.
