The enhanced workflow was used in all cases providing intra-operative feedback regarding broach and stem version, combined anteversion and guiding neck resection. Robotic arm assistance was used to perform reaming in the desired plane with the utilisation of stereotactic boundaries. The acetabular cup was also positioned with the assistance of the robotic arm and the haptic tunnel that maintains the planned orientation during implantation. In this prospective cohort study, all patients received a cementless femoral stem (Accolade II; Stryker, Mahwah, NJ, USA) and a peripheral self-locking porous acetabular shell (Trident PSL shell; Stryker).
Trident psl shell
Manufactured by Stryker
Sourced in United States
The Trident PSL shell is a component designed for use in Stryker's joint replacement products. It serves as a critical part of the implant system, facilitating the secure attachment of the implant to the patient's bone. The Trident PSL shell is engineered to provide a stable and durable interface between the implant and the patient's anatomy.

From November 2018 to April 2022, 457 THA procedures were performed in our hospital. Institutional review board approval was obtained before initiation of the study, and written informed consent was obtained from all included patients. Among these procedures, we included 56 hips of 54 patients who underwent primary THA using the Trident HA acetabular system (Stryker, USA) for osteoarthritis and osteonecrosis of the femoral head, and who agreed to participate in this study (Figure 1 ). Patient characteristics are shown in Table I .
Because use of the Trident PSL shell (Stryker) was our first-choice protocol, and the Trident hemispheric multi-hole cup was used with a different operative protocol (2 mm under-reaming) when the surgeons judged the patient to be at high risk of initial fixation failure, hips that underwent treatment with the Trident hemispheric multi-hole cup were excluded from this study. Moreover, any hips in which press-fit fixation was reattempted after initial failure were excluded from the analysis because of the possibility of procedural heterogeneity.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
