1. Onset is usually before the age of 55 years
2. There is clear history of previous trauma
3. In most cases, single joint is affected
Select the correct answer using the code given below:
This section analyzes the key characteristics of early onset osteoarthritis (OA) based on the provided statements.
This statement is considered false in the context of the correct answer. While OA occurring at younger ages is termed "early onset," the specific age threshold can vary, and it is not universally defined as *usually* before 55. Other factors often define it more significantly.
This statement is considered true. Early onset osteoarthritis is often linked to specific predisposing factors, with a history of previous joint injury or significant trauma being a common contributor, particularly in younger individuals.
This statement is considered true. When early onset OA is associated with specific causes like localized trauma or mechanical issues, it frequently affects a single joint initially, differentiating it from generalized OA patterns.
Based on the analysis, statements 2 and 3 accurately describe common features associated with early onset osteoarthritis, especially when considering specific causative factors.
Therefore, the correct option includes only statements 2 and 3.
