Study summary

Through this cohort study, previous clinical data can be systematically reviewed and supplemented through clinical follow-up. Prospective enrollment and follow-up observation of subsequent patients can also be carried out to build a retrospective-prospective two-way cohort study. The intraoperative, perioperative, clinical follow-up and health economics of surgical robot, computer navigation, personalized osteotomy guide and other digital technologies and traditional TKA were comprehensively and objectively compared, the results and conclusions of the center were summarized and reported, and the effectiveness and safety of digital assistive technology applied to TKA were explored, providing references for clinical diagnosis and follow-up research.

Eligibility

Primary outcome measure(s)

• mechanical axis — Postoperative day 3
  The postoperative HKA Angle was measured, that is, the Angle between the center of the hip joint and the center of the knee joint and the center of the knee joint and the center of the ankle joint on the full-length X-ray film of the lower limb. The target Angle was defined as 0°, the Angle was positive when the knee was varus, the Angle was negative when the knee was varus, and the acceptable range was ±3°, beyond which the line deviation was defined.
