About this trial

This is an interventional treatment trial for Knee Osteoarthritis focused on measuring Knee Osteoarthritis, Total Knee Arthroplasty, Customized Cutting Block, Conventional Intramedullary Cutting Guide

Eligibility Criteria

60 Years - 90 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Age 60-90
  • Diagnosis of osteoarthritis or rheumatoid arthritis of the knee and qualify for surgery, as indicated by one of the following:
  • Painful and disabled knee joint resulting from osteoarthritis where one or more compartments are involved;
  • Correction of varus or valgus.
  • Willing to participate and return for follow-up study visits.

Exclusion Criteria:

  • Vascular insufficiency
  • Previous deep vein thrombosis and pulmonary embolism
  • Previous osteotomy
  • Previous patella fracture or surgery
  • Previous healed tibia or femur fractures
  • Previous joint replacement surgery

Sites / Locations

  • Thammasat University Hospital.

Arms of the Study

Arm 2

Arm Type

Active Comparator

Active Comparator

Arm Label

Standard knee cutting guides

Patient specific cutting guides

Arm Description

Standard cutting guides use traditional instrumentation to determine knee implant positions. During surgery, a rod is placed in the leg bone and the cutting guide is attached to that rod.

Patient specific cutting guides are custom-made for each patient based on Magnetic Resonance Imaging (MRI). Before surgery, MRI of the knee is done and used to create a cutting guide that is formed to the exact shape of the knee. The patient specific cutting guides have platforms that can be attached to the bone, so the rod does not need to be placed in the leg bone.

Outcomes
