Purpose:
The purpose of this study was to compare non-fiducial based surface registration technique (DigiMatch) with the conventional locator pin-based registration technique in performing cementless total hip arthroplasty (THA) using ROBODOC system.
Methods:
Eighty-one THA were performed using pin-based technique and forty-three were performed using the DigiMatch technique. The average follow-up term was 38 months.
Results:
Postoperatively, the Japanese Orthopedic Association hip scores were significantly better in the DigiMatch group than in pin-based group. The accuracy of postoperative stem alignment of the DigiMatch technique was comparable with that of pin-based method.
Conclusions:
No need for prior pin implantation surgery and no concern for pin related knee pain were the advantages of DigiMatch technique. Short-term follow-up clinical results showed that DigiMatch ROBODOC THA was safe and effective.
