In CPM, which value could be within the initial 20-40 degree range?

• A. 15 degrees
• B. 25 degrees
• C. 45 degrees
• D. 60 degrees

Answer: (B)

Continuous Passive Motion devices aim to protect healing tissues by starting with a conservative knee range of motion after surgery. The initial setting is kept within a modest window, often around 20–40 degrees, to reduce stress on tissues while still promoting movement. A value of 25 degrees falls inside that 20–40 degree range, making it a suitable initial setting. The other options are either below the lower limit (15 degrees) or above the typical initial window (45 and 60 degrees), so they wouldn’t be used as the starting range.
