ALCARE Made in Japan Knee Support Cast - Size L This was purchased at the hospital when a family member injured their knee about two weeks ago. New ones are expensive, so I hope this can be useful for someone who needs it. The tape's adhesive strength is not an issue. There is a feeling of use, but it is still in a condition where it can be used. Please purchase if you understand that this is a used item. I cannot answer specialized questions. There is no original box. ALCARE's "Knee Brace FX (Size L)" is a medical support (cast substitute) that firmly fixes the knee joint in a slightly flexed position (approximately 10°). It is ideal for post-operative and ligament injury fixation, and uses long belts compatible with icing and comfortable cotton pile fabric. It supports a thigh circumference of 47-54cm and reduces pressure with side pads.
