Total knee arthroplasty (TKA) is widely used to treat end-stage knee disorders, but its role in ankylosed knees has long been debated due to the technical complexity and heightened risk of complications. A recent study has provided important insights, showing that although patients with ankylosed knees experience lower recovery of range of motion (ROM) and face higher complication rates compared with conventional osteoarthritis cases, Total knee arthroplasty still delivers meaningful improvements in function, mobility, and quality of life. In this retrospective analysis, researchers evaluated outcomes of patients with ankylosed knees who underwent Total knee arthroplasty. Preoperatively, most patients had severely restricted or no motion, limiting independence and quality of life. After surgery, despite achieving less ROM than patients with non-ankylosed knees, participants reported significant improvements in flexion, extension, walking ability, and pain reduction. These functional gains translated into higher satisfaction levels and improved performance in daily living activities. However, the study also highlighted the elevated risk profile of Total knee arthroplasty in this population. Complications such as periprosthetic fractures, wound healing problems, prosthetic loosening, and infections occurred more frequently. Recovery of knee mobility was often incomplete, with gains falling short of those seen in routine arthroplasty. The findings emphasize the need for realistic preoperative counseling, careful surgical planning, and close postoperative monitoring. Despite these challenges, the clinical impact of Total knee arthroplasty in ankylosed knees was substantial. Even modest improvements in knee motion allowed patients to regain independence, reduce reliance on assistive devices, and improve psychosocial well-being. The study suggests that Total knee arthroplasty can be considered a viable and effective treatment option in patients with ankylosed knees, provided that both patients and surgeons are aware of the potential risks and limitations. Overall, this research reinforces the view that while Total knee arthroplasty in ankylosed knees carries higher complexity and complication rates, it remains a transformative intervention, improving mobility, functional independence, and quality of life in a patient group that otherwise faces profound disability.
