Abstract:
Three-dimensional printed patient-specific instrumentation (3D-PSI) provides a precise and individualized treatment solution for unicompartmental knee arthroplasty (UKA). Currently, this technology is being applied in clinical practice and has demonstrated certain potential. Compared to conventional instrumentation (CI), 3D-PSI offers a broader range of indications, higher-quality preoperative planning, shorter surgical time, a smoother learning curve, more precise osteotomy and prosthesis placement, and better postoperative functional recovery. However, it still has limitations in the rotational alignment of the tibial component. Additionally, the higher cost for patients and increased hospital equipment investment make it less beneficial for surgeons already proficient in CI techniques. Further reliable evidence is needed to compare 3D-PSI with computer navigation and robotic technologies. This review summarizes the advantages and limitations of 3D-PSI assisted UKA and compares 3D-PSI with different auxiliary technologies.
