When the second design project was introduced, Dr. McDonald introduced many different methods of inserting a hip prosthesis into a patient’s hip. He talked about many periods where it was crucial to operate and suitable patients.

Therefore, when my team received our patient profile, I was very ready to assess which type of hip failure could relate to which area and start the process. However, our patient already had a hip prothesis, what was to occur then?

Our team was given a goal to create a solution for a patient experiencing pain in the area surrounding their previous hip prothesis. The diagnosis was determined to be aseptic loosening as a result of **[osteolysis](https://pubmed.ncbi.nlm.nih.gov/15552150/#:~:text=Osteolysis is defined as the,bone or cement-bone interface.)**.

We aimed to create an innovative design using spikes on the acetabular cup to increase surface area and a “wall-plug” design to allow ease of insertion while ensuring a secure fit.
