A complex TKA in a post-traumatic arthritic knee with a significant bone loss: A case report and literature review

INTRODUCTION: Total knee arthroplasty is an effective procedure that aims at restoring function and relieving pain. While most surgeons are familiar with primary TKA, some secondary cases are unique and might create a challenge. CASE PRESENTATION: A young 30-year-old male with no comorbidities had a gunshot injury to his knee. He developed knee arthritis later, which was treated with modular TKA and a cement-screws technique for substitution for bone loss. DISCUSSION: Complex cases of TKA demand innovative solutions, many options exist now for dealing with various challenges, but they are expensive and not always available, so other choices must be utilized to afford the best possible outcome. CONCLUSION: Post-traumatic TKA could be technically challenging, and screws buttressing the cement could effectively handle bone defects when other options are unavailable.
