Background
Tendon and ligament injuries around joints are common injuries of orthopaedics, and suture anchors are commonly used clinically to fix damaged tendon stumps to bone tissues so as to restore normal structures and joint functions of the tendons, and the purpose of final fixation is achieved through tendon bone healing.
The process of healing of the tendinous bone requires a certain contact area of the tendon with the rough surface of the bone end and firm contact stability. Thus, the fixation strength of the anchor in the bone is the key and basis for the success of the procedure.
Most of the current suture anchors in the current market are provided with a thread structure on the main body of the anchor, and the aim of fixation is achieved by pre-drilling a channel with the diameter slightly smaller than the diameter of the anchor and then screwing in or directly beating into bone through rotation. However, most of the anchors are micro anchors with a diameter of 3.5mm or less, and compression stability generated by threads and bone tissues is limited. The phenomena of anchor loosening and pulling out after the anchor is fixed clinically often occur, such as fixation failure and operation failure, particularly in cases of bone mass reduction or osteoporosis, and joint positions such as large joint movement range, strong tendon force, shoulder and elbow and the like are more likely to occur.
