The Subvastus Approach in Total Knee Arthroplasty

The Subvastus Approach in Total Knee Arthroplasty

The purpose of this study is to determine if the observed benefits of minimally invasive total knee arthroplasty, namely decreased hospital stay and increased range of motion, can be achieved with standard knee arthroplasty using the subvastus approach.

Inclusion Criteria:

• You are willing to take part in the study, including signing this form after carefully reading it.
• You are available for follow-up for a minimum of 24 months (2 years).
• You have no medical conditions that prevent you from having surgery.

• You are fluent in English and are able to understand your responsibilities in this study.

Exclusion Criteria:

• Active, local or systemic infection
• Fibromyalgia or other chronic pain syndrome
• Inability to follow the study requirements
• Had this knee replaced before
• Had a previous surgery on this knee that would interfere with the MIS approach (examples are femoral-femoral bypass, femoral-popliteal bypass, and quadricepsplasty)
• Body Mass Index (BMI) > 35, as you would not be eligible for the MIS approach.
