Minimally invasive total knee arthroplasty: Suspended leg approach and arthroscopic-assisted techniques

Abstract

Minimally invasive total knee arthroplasty relates to techniques and approaches due to reduce the overall soft tissue exposure and perform TKA. Often, this is defined as different types of muscle sparing approach. Additional techniques such as mobile window have been utilized to enhance exposure. We described techniques using a suspected leg i.e. patients leg supported in the leg holder and distracted by gravity to enhance exposure as adjunct to MIS technique. To improve visualization, the surgeon can be seated and variably flex and extend the knee. If additional visualization is required, arthroscopic assistance in either dry environment or fluid environment can enhance visualization and exposure, ligament balancing, tissue release, tissue, bone, cement removal as an adjunct in the procedure. With suspected leg and arthroscopic assistance, it enhances MIS techniques and may improve recovery.
