In the last 30 years there have been improvements in how rotator cuff tendon are reattached to the bone, and the tools used to accomplish this, but there have been limited improvements in the healing of the tendon to the bone (Ricchetti, E.T., et al., Scaffold devices for rotator cuff repair. Journal of Shoulder and Elbow Surgery, 2012. 21(2): p. 251-265.).
All Bone/Tendon interface injuries face common challenges:
They heal by scar tissue formation with inferior mechanical properties
The healing time is often 3 to 6 months or more to achieve full function
Scar tissue weakens the quality of the repair
The Rotium™ Bioresorbable Wick is used with suture anchors for the reattachment of tendon to bone in rotator cuff repairs. It is a non-woven, microfiber matrix comprising biodegradable polymer fibers that mimic the extracellular matrix structure.
Rotium™ supports cellular infiltration and migration, and facilitates functional tissue regeneration. The Rotium™ Wick is designed to be fully absorbed within 3-4 months and is replaced by neo-native tissue.
The Rotium™ scaffold is placed on the humeral head and under the tendon during open or arthroscopic procedures and is compatible with all brands/types of anchors. The biodegradable polymer nanofiber scaffold assists the migration of cells into the bone/tendon interface replicating the structure of the native extracellular matrix. Designed to improve Sharpey fiber formation and completely resorb after 3-4 months, the result is significantly improved repair strength and faster return to normal function.
Rotium™ benefits payors and providers by providing a lower overall cost per procedure, with greater benefit (i.e. wick retention and strength) compared to similar devices. Alternative scaffold products cost upwards of $3,500, whereas Rotium™ costs $1150.
Rotium™ is FDA indicated to be used in conjunction with over 40 commonly used anchors. Similar products on the market only have 1 suture anchor product configuration.
Ease of use allows for incorporation into existing repair techniques without adding time.
No change is required in placement configuration for existing anchors or procedures - no special instrumentation is required.
Rotium™ can be used in open or arthroscopic procedures.
Rotium™ provides over 9 times the surface area coverage than comparable products, with a surface area of 400 sq. mm.
Rotium™ provides optimum coverage of the supraspinatus footprint of 368 sq. mm.
Rotium™ benefits patients, surgeons, and insurers by providing a lower overall cost per procedure than comparable products while offering greater benefits, such as increased wick retention and strength.
