BACKGROUND: Greater trochanter decortication is frequently performed at the time of abductor tendon repair to theoretically increase healing potential. No previous studies have determined the effect that greater trochanter decortication has on the pullout strength of suture anchors. Hypothesis/Purpose: The purpose of this study is to determine whether greater trochanter decortication and bone mineral density affect suture anchor pullout strength in abductor tendon repair. The authors hypothesize that both will have a significant detrimental effect on suture anchor pullout strength...

Biomechanical studies have shown the use of suture anchors (SA) to be superior to the traditional transosseous sutures (TS) in the repair of quadriceps tendon rupture (QTR). This study aimed to analyze and compare the functional outcomes of patients treated for quadriceps tendon ruptures using suture anchors or transosseous sutures. Patients having undergone suture anchor repair or transosseous suture repair for quadriceps tendon rupture between 2010 and 2015 at one of the two participating hospitals were included...

Anterior cruciate ligament (ACL) tears are usually managed by reconstruction with autograft or allograft, but primary repair in carefully selected patients is a reasonable option. Proximal avulsions presenting early with excellent tissue quality are amenable to repair and healing. Restoration of native ACL preserves its proprioceptive and kinematic functions. A repair is less invasive and avoids graft-related problems, and faster rehabilitation is possible. Protection for the repair in the early stages will allow better healing...

There are multiple etiologies for recurrent patellar instability. While patella alta, an elevated tibial tubercle trochlear groove distance, and prior lateral patellar dislocations with medial patellofemoral ligament (MPFL) insufficiency have been shown to be risk factors for recurrent patellar instability, trochlear dysplasia can result in a significant impediment to normal patellar tracking. With the adequate identification of risk factors, appropriate surgical treatments can be individually tailored to the patient...

Latissimus dorsi tendon transfer is an effective option for young and active patients with massive irreparable posterosuperior rotator cuff tears and intact subscapularis tendon. This approach has been shown to relieve pain and improve shoulder function in both the short and long term. We describe a surgical technique using an acromial osteotomy to better expose the greater tuberosity for the tendon transfer without disrupting the deltoid muscle. The latissimus dorsi tendon is reinforced with a human dermal collagen matrix (GraftJacket; Wright Medical Group) for additional augmentation of the muscle to gain more excursion for the tendon transfer to the greater tuberosity...

The lateral collateral ligament (LCL) complex of the elbow plays a crucial role in the stability of the elbow joint, especially to varus loads. Deficiency of particularly the lateral ulnar collateral component of the LCL can lead to chronic posterolateral rotatory instability, which can be functionally debilitating and can lead to a rapid onset of early degenerative arthritis. Commonly, in the setting of acute rupture of the LCL, the ligament is repaired using an open technique with suture anchor fixation to the lateral epicondyle insertion point...

PURPOSE: With the aim of implementing good projection of the three-dimensional frame (auriculo-cephalic angle) and maintaining projection, a significant issue during the stage of auricular elevation for avoiding the potential for dislodging the cartilage blocks remains. Herein we present an innovative and technically simple method of transcutaneous fixation of the costal cartilage block during the stage of auricular elevation. MATERIALS AND METHODS: After elevation of ear frame from the basement, two suspension stitches on the surface of the elevated ear were used to fix the embedding cartilage block into the auriculo-cephalic sulcus at the upper (bifurcation point of the anti-helix where the inferior and superior crus meet to form the triangular fossa) and lower (projection point of the concha wall, parallel to the level of the tragus) ones...

Fibular head avulsion fractures are rare injuries determined by traction of the fibular attachment of the lateral collateral ligament (LCL). Surgical treatment is often recommended with different techniques such as tension band fixation or lag screws stabilization. In this article, we describe a fixation technique of fibular head fractures obtained through the use of anchors. A 45-year-old athletic patient came to our attention in our traumatologic service after a motorcycle accident. He reported a complex injury of the posterolateral corner with an avulsion fracture of the left fibular head...

We report a case of a partial rupture of the distal biceps tendon that was surgically treated using a palmaris longus tendon graft. A 58-year-old man complained of increasing pain with resisted elbow flexion and supination in the antecubital fossa. Magnetic resonance imaging revealed the irregularity of a distal attachment of the biceps brachii and peripheral signal changes. We diagnosed a partial rupture of the distal biceps tendon. Because conservative treatment failed, surgical treatment was performed through a single anterior approach...

BACKGROUND: Weight regain after Roux-en-Y gastric bypass affects up to 30% of individuals. A dilated gastrojejunostomy contributes to regain through decreased restriction. Endoscopic gastrojejunostomy revision is a safe alternative to revisional surgery. There is evidence that technique affects outcome, but the mechanical properties of various sutured repairs have not been evaluated. OBJECTIVE: To compare different suture patterns for endoscopic gastrojejunostomy revision using an ex vivo porcine model...

PURPOSE: The aim of this study was to observe the surgical outcomes of suture globe fixation to the orbital wall for patients with complicated strabismus. MATERIALS AND METHODS: The medical records of patients with complicated strabismus who were treated at the Zhongshan Ophthalmic Center of Sun Yat-sen University, Guangzhou, China, from January 2010 to June 2015 were retrospectively reviewed. Routine strabismus surgery was not possible in these cases. Eyes were anchored to the orbital wall by simple strong anastomosis of the extraocular muscle and orbital wall tissues using silk suture, which resulted in slight overcorrection of the ultimate ocular position after anchoring...

Numerous suture techniques and covering flaps have been described to minimize complications related to sutures in otoplasty. The split postauricular fascial flap is one of such techniques, and it has been used to pad otoplasty suture. The aim of this study was to evaluate complications related to nonabsorbable cartilage sutures in otoplasty, using a variation of the split postauricular fascial flap. In this retrospective case series, we analyzed otoplasty patients in whom simplified split postauricular fascial flap was utilized...

BACKGROUND: Knotless barbed sutures are monofilament sutures with barbs cut into them. These sutures self-anchor, maintaining tissue approximation without the need for surgical knots. OBJECTIVE: The hypothesis of this study was that knotless barbed suture could be used on the myometrium to close the hysterotomy at cesarean delivery. The objective was to compare uterine closure time, need for additional sutures, and blood loss between this and a conventional suture...

The aim of this study was to assess the efficacy and safety of a novel magnesium-based resorbable bone cement (OsteoCrete, Bone Solutions Incorporated) for anchor and tendon fixation. Cadaveric humeral testing involved straight pull-to-failure of rotator cuff suture anchors; OsteoCrete was injected through one anchor, and a second anchor served as the uninjected control. Testing was conducted 15 minutes post-injection. A canine preclinical model was used to evaluate the safety of the following parameters: Rotator cuff repair: A double-row technique was used to repair transected infraspinatus tendons; OsteoCrete was injected through both anchors in one limb, and the contralateral limb served as the uninjected control...

CASE: A snapping biceps femoris tendon, a rare etiology for symptomatic pain in the lateral aspect of the knee, has been reported infrequently. We report 2 cases of an acutely symptomatic unilateral snapping biceps femoris tendon with an intraoperatively intact anomalous insertion onto the tibia, which were treated with anatomic repositioning and "pie-crust" lengthening via a single suture anchor. CONCLUSION: Anatomic repositioning and lengthening is a novel technique that successfully resolved the painful snapping and allowed full return to competitive sports by 6 months postoperatively, with maintenance of improvement at ≥14 months postoperatively...
