- These above-knee ranges are identical in the legacy Knee Skin 4110 catalog and the current Knee Compression Sleeve 4110 sizing chart. Values in each unit are reproduced as published, not converted.
- This table reproduces only the above-knee columns. The legacy catalog also measures at mid-patella, while the current chart instead measures below mid-patella; those different measurement locations are not interchangeable.
- BFY's listing shows S, M, L, XL and XXL. XS and extended sizes are manufacturer-listed; confirm availability and the supplied version with BFY.
