Artrhoplasty, Knee Replacement


Introduction: The purpose of this study was to describe the characteristics among total knee replacement (TKR) patients in St. Carolus Hospital from year 2016-2020 as the surrogate model for the non-existing National Joint Registry.

Methods: Data were extracted from the TKR registry data of a single institution from 2016-2020. Patient demographic data were collected. Intraoperative characteristics were defined as: (1) Utilization of computer navigation system; (2) Type of implants; (3) Type of tibial component; (4) Implant name. Post-operative characteristics were defined as: (1) Length of hospitalization (days); (2) Complication rate (%); (3) Revision event (%). The complication rate included: (1) Deep vein thrombosis; (2) Prosthetic joint infection; (3) Periprosthetic fracture.

Results: A total of 784 primary TKR procedures were performed in 5 years. The average age of the patients was 68.2 years. The metal back tibial component was used more (64%) compared to all polyethylene tibia, meanwhile cruciate-retaining was the most frequent type of implant (74%). The utilization of computer navigation systems was 67%. The average length of hospitalization was 4.3 days. The complication rate was low (6.2%) and the revision rate was 0.3%.

Conclusion: The complication and revision rate following primary TKR was low at our institution’s joint registry. Our data provides the characteristic of TKR in Indonesia as the mini joint registry of the country, thus necessitate collaboration with multiple centres to achieve a comprehensive national joint registry.
Level of Evidence: Descriptive study, level III
