Single trabecular titanium Cup-Cage for acetabular bone defects during revision hip arthroplasty: Mid-term outcomes

The Delta TT system offers a reliable and biologically favorable solution for managing severe acetabular defects in rTHA. Its porous trabecular titanium structure and modular design promote durable fixation, radiographic stability, and significant functional recovery, with low complication rates. These mid-term results support its role as a valuable reconstructive option in complex revision hip arthroplasty. Long-term and comparative studies are warranted to further validate durability and outcomes.
