Case: A 76-year-old man presented with periprosthetic tibial plateau fracture (TPF), with a completely loosened tibial component 3 weeks after cementless unicompartmental knee arthroplasty (UKA). Internal fixation by buttress plating was performed, and the tibial component was retained and left in situ primarily as a spacer. Revision was planned after fracture consolidation, but at 3 months, the patient was able to walk without support, without pain, and with full range of motion. At 1 year, he is free of complaints. The initial loosened tibial component reintegrated.
Conclusion: Internal fixation combined with preserving the loosened tibial component may be a treatment option for TPF involving a cementless UKA.

Background: Ultracongruent (UC) total knee replacement (TKR) designs, serving as alternatives to posterior stabilized (PS) and cruciate retaining (CR) designs, lack conclusive evidence regarding posterior femoral rollback. This study aimed to compare intraoperative posterior femoral rollback and maximal knee flexion between UC and PS inserts, addressing the paucity of literature on femoral rollback achieved with UC designs in total knee replacement.
Methods: A consecutive cohort of 20 patients undergoing robotic-assisted primary total knee replacement, posterior femoral rollback and maximal intraoperative knee flexion were assessed.

Large bone defects are a major clinical challenge in bone reconstructive surgery. 3D printing is a powerful technology that enables the manufacture of custom tissue-engineered scaffolds for bone regeneration. Electrical stimulation (ES) is a treatment method for external bone defects that compensates for damaged internal electrical signals and stimulates cell proliferation and differentiation.

Medium chained triglycerides (MCT) ketogenic diet is being extensively investigated for its neuroprotective effects against adverse effects associated with aging and neurodegenerative disorders. Aging is a common risk factor for the development of both osteoporosis and neurological disorders. Hence, suppression of aging and age-related neurodegeneration might contribute to delaying skeletal aging.

Purpose: Unicompartmental knee arthroplasty (UKA) is a viable option for localized osteoarthritis (OA) or avascular osteonecrosis with several advantages over total knee arthroplasty (TKA). UKA implants may feature a tibial component either all-polyethylene (AP) or metal-backed (MB). This study aims to retrospectively compare the clinical outcomes and survivorship of 74 UKAs over 16 years, focusing on comparing the results and survivorship of MB versus AP tibial tray.

Background: Unicompartmental knee arthroplasty (UKA) procedures have become much more common in the United States in recent years, with >40,000 UKAs performed annually. However, it is estimated that 10% to 40% of UKAs fail and thus require conversion to total knee arthroplasty (TKA). In the field of total joint arthroplasty, robotic-assisted surgeries have demonstrated advantages such as better accuracy and precision of implant positioning and improved restoration of a neutral mechanical axis.
