Managing of Post-traumatic Knee Arthritis by Total Knee Arthroplasty: Case Report and Literature Review

Abstract

Introduction: Post-traumatic knee osteoarthritis (PTOA) develops rapidly after injuries from sports, accidents, or falls. Unlike primary osteoarthritis, PTOA escalates quickly, causing severe joint damage and impairments. Early intervention is crucial to alleviate pain, restore function, and prevent further deterioration. Delayed treatment worsens symptoms and increases the need for invasive procedures like total knee arthroplasty (TKA). Case Presentation: A 29-year-old patient with a year of left knee pain, swelling, and difficulty straightening had no history of rheumatic or autoimmune diseases. Examination showed osteophytes, indicating osteoarthritis. He underwent TKA with no complications, achieving a satisfactory outcome: good range of motion, improved quality of life, and an Oxford Knee Score of 42. Discussion: PTOA typically follows trauma to the joint surface, with severity often correlating with the impact intensity. In this case, the patient’s rapid development of osteoarthritis, despite his young age and lack of pre-existing conditions, may suggest a genetic predisposition. Knee arthroplasty was chosen to restore function, aligning with research showing comparable outcomes for post-traumatic and primary osteoarthritis patients, though post-trauma cases can have higher complication rates due to comorbidities. Conclusion: Effective management of PTOA is crucial due to its rapid progression and significant impact on joint function and quality of life. Early intervention is key to preventing severe damage and reducing the need for invasive treatments. While TKA can be effective, its success depends on the severity of the condition. Timely management and preventive strategies are vital to improving outcomes and maintaining joint health.
