- The exact manufacturer's chart is labeled Fusion OA Plus. It includes M+ as a separate stock size.
- The manufacturer's published inch and centimeter values are retained without recalculation; the published 6-inch measurement location is also labeled 15 cm.
- The chart states that brace length starts at 13.5 inches and varies by size; individual size lengths are not supplied.
- Size codes are the XX suffixes in the manufacturer's prefabricated part-number families, not public variant identifiers.
- The supplied page lists separate left and right prefabricated configurations. It does not publish different left/right circumference ranges.
- Separate women's and custom configurations are listed on the source page, but no separate circumference chart for them is verified here. This table is not a custom-size chart and is not transferred to the separate women's model.
- Adjacent ranges share endpoints. The manufacturer chart does not specify a boundary rule or a rule for measurements falling in different size rows.
- This chart documents the current OA Plus model on the supplied page, not a verified legacy non-Plus Fusion OA chart or the separate Fusion ligament and Lateral OA models.
