#1
Susumu Tokunaga, Yoshihiro Abe
Collateral ligaments are difficult to repair due to large amount of fraying in detached ligaments and attenuated stumps that may not provide enough strength after the repair. Although strong locking sutures are used to repair the ligament with proper tension, these damages can cause pull-out failure or relaxation of the repaired ligaments even from undersized load that may extend postoperative splinting or casting time. Furthermore, current suture techniques can repair varus or valgus instability of the elbow and radial or ulnar instability of the fingers, but these techniques do not offer rotatory stability of these areas...

OBJECTIVE: The goal of this operation technique is a stable refixation of the triangular fibrocartilage complex (TFCC) to the fovea ulnaris. The stability of the distal radio-ulnar joint (DRUJ) should be re-established. The patients pain and the feeling of instability should be reduced. INDICATIONS: Lesions of the foveal component of the TFCC resulting in DRUJ instability. Combined lesions of both components of the TFCC. Complete detachment of the TFCC from the ulna either without fracture of the styloid process of the ulna or with fracture (floating styloid)...

BACKGROUND: Rotator cuff tears are of increasing clinical impact in the physically active elderly patients. Recent research revealed, that a high percentage of these patients present with significant loss of bone mineral density at the insertion site of the rotator cuff, thereby compromising suture anchorage for operative repair. We therefore hypothesized that augmentation of suture anchors improves biomechanical properties in low bone quality. METHODS: 28 osteoporotic humeral heads were included in this biomechanical study...

PURPOSE: The use of graft tissue fixation using bioabsorbable interference screws (BISs) in anterior cruciate ligament (ACL) reconstruction offers various advantages, but limited pullout strength. Therefore, additional tibial fixation is essential for aggressive rehabilitation. We hypothesized that additional graft tissue fixation using bioabsorbable suture anchors (BSA) would provide sufficient pull-out strength. MATERIALS AND METHODS: Twenty four fresh frozen porcine distal femur and patellar tendon preparations were used...

Chronic insertional tendinopathy of the Achilles tendon is a frequent and disabling pathologic entity. Operative treatment is indicated for patients for whom nonoperative management has failed. The treatment can consist of the complete detachment of the tendon insertion and extensive debridement. We biomechanically tested a new operative technique that uses buttons for fixation of the Achilles tendon insertion on the posterior calcaneal tuberosity and compared it with 2 standard bone anchor techniques. A total of 40 fresh-frozen cadaver specimens were used to compare 3 fixation techniques for reinserting the Achilles tendon: single row anchors, double row anchors, and buttons...

Complete distal biceps tendon rupture causes a considerable loss of supination and flexion strength, and thus, surgical repair is indicated in active individuals. To reduce the risk of injury to the radial nerve in the confined space where the distal biceps inserts into the radius, several surgical methods have been reported, such as, pull out sutures, two-incision techniques, and the use of suture anchors. Here, we describe our modified single-incision distal biceps tendon repair technique using three suture anchors, which widens the bone-tendon contact surface and simplifies tensioning of the tendon attachment...

PURPOSE: To quantify the strength of suture fixation of knotless suture anchors in relation to the anchors' pullout strength and to compare these results with the static friction between different sutures and anchor materials. METHODS: Suture slippage within the anchor and pullout strength of 4 different knotless suture anchor models were assessed in a bovine bone model. Furthermore, the peak force before onset of slippage of different sutures trapped between increasingly loaded 4-mm rods made of commonly used anchor material (polyetheretherketone, poly-L-lactide acid, metal) was assessed...
