NCT04235283

Brief Summary

The purpose of this study is to conduct a prospective randomized clinical trial to compare the accuracy of prosthesis, radiographic alignment, total blood loss, the risk of venous thromboembolism between pinless-navigated total knee arthroplasty (TKA) and traditional TKA.

    The anatomic alignment (AA): an angle between the axis of the femoral shaft and the tibial shaft axis

Study Arms (2)

Group I

EXPERIMENTAL

Primary total knee replacement by pinless navigation and minimally invasive technique

Device: Primary total knee replacement by pinless navigation (Orthomap Express,Stryker, Michigan)

Group II

ACTIVE COMPARATOR

Primary total knee replacement by traditional jig and minimally invasive technique

Procedure: Primary total knee replacement by traditional jig and minimally invasive technique

Interventions

The varus/valgus, extension/flexion, thickness of distal cut of femur was determined and done by pinless navigation system. After cutting, the instant information of resection level can show on the display screen. If the alignment is satisfying, the anterior/posterior femoral cut, chamfer cut and box resection were done by conventional jig

Group I

The femoral alignment was determined by intramedullary guide. The femoral alignment jig was set to 5-7 degree valgus dependent on the preoperative radiograph. A bone plug is impacted into the entry hole of femoral medullary canal before prosthesis placement.

Group II

Masking Details
This study proposed 1:1 randomization into pinless navigation and conventional technique. Each patient who enrolled in this study will be given sequence study number, and the chief surgeon will draw lots to decide which group will be assigned in. The patient and the independent reviewer are kept blinded

Intervention Model
PARALLEL
Model Details: Enroll 100 patients who plan to undergo unilateral primary MIS-TKA and will be randomly assigned into two groups. The first group (50 patients) will be treated by pinless-navigation (Stryker, OrthoMap Express Knee Navigation) MIS-TKA, and the second group (50 patients) will undergo traditional MIS-TKA.
