Minimally Invasive Surgery

Minimally invasive surgery for orthopaedic conditions allow a more rapid return to normal function, and reduces the load on the body after surgery. In general, minimally invasive surgery is more technically demanding, but can result in a more rapid rehabilitation. The concept of minimally invasive techniques for hip and knee surgery is not new. For decades, orthopaedic surgeons have been looking for ways to improve the outcomes of patients by reducing the areas that need to heal after surgery.

For arthritis, total hip replacements, and total knee replacements can be performed via minimally invasive approaches. These are not commonly used often as they can be more difficult to perform, and have a learning curve that is longer than other methods. Some studies show benefits whilst others do not. Once trained and competent, these techniques can yield benefits above and beyond what other methods can.

Dr Chien-Wen Liew is a true believer of minimally invasive surgery, and has trained in techniques on hip and knee arthritis, sports injury, as well as in trauma surgery. For surgery to be minimally invasive, it is what occurs under the skin that is more important than the size of the skin incision. In most cases, muscles and nerves should be respected (i.e. using tissue planes that go between areas supplied by different nerves), and bleeding should be reduced. A decrease in blood loss may also reduce infection risk as there is less haematoma under the skin to act as a nidus for infection. Orthopaedic surgeons can utilise a multitude of approaches to the hip and knee, and often it is the one that they perform most frequently that has the best outcomes in their hands.

In total hip replacements, the Direct Anterior Approach uses a muscle plane that goes between muscles of the hip, avoiding cutting them from bone. The recovery and rehabilitation after a total hip replacement performed via a Direct Anterior Approach is in general, fast.

For total knee replacements, Dr Liew performs a medial parapatellar approach. A lateral skin incision is often used now to improve post operative kneeling. The VMO (Vastus Medialis) remains attached to the quadriceps mechanism.

Dr Chien-Wen Liew gives regular patient and doctor talks on performing the Direct Anterior Approach for total hip replacements and Patient Specific Technology for Total Knee Replacements.
