Comparing Early Outcomes of Standard and Subvastus Approach in Mobile Bearing Cruciate Retaining Total Knee Arthroplasty in BMA General Hospital ; A Randomized Controlled Trial Study

Phase 3

Completed

• Conditions: Secondary osteoarthritis from Inflammatory arthritis ,Infective arthritis , Posttraumatic arthritis , previious knee surgery, age more than 90 yrs, BMI more than 38; Early outcome, Subvastus approach,Standard approach in Mobile bearing cruciate retaining total knee arthroplasty

• Registration Number: TCTR20221223002
• Lead Sponsor: Bangkok metropolitan administration general hospital

Brief Summary

TKA using mobile bearing with cruciate retaining design by subvastus approach have less operative time than medial parapatellar approach. Maybe due to the design of MB prosthesis that have less steps of operation, furthermore, the less operative and tourniquet times conducts less blood loss. Subvastus approach probably increase the angle of active straight leg raising, presuming improvement in quadricep muscle function.
