INTRODUCTION: Combined anterior cruciate ligament (ACL) and posterolateral corner (PLC) reconstruction are a rare clinical entity in orthopedic literature, whose management requires different types of tendon grafts. Missed PLC injury leads to the failure of ACL repair due to the joint instability. PRESENTATION OF CASE: We are presenting a case of posttraumatic right ACL, PLC and lateral meniscus injury. The patient was taken to theatre for arthroscopic meniscectomy, ACL and PLC reconstruction...

Sung-Min Rhee, Nam Yun Chung, Hyeon Jang Jeong, Joo Han Oh
BACKGROUND: Subacromial pain pumps are used for analgesia after arthroscopic rotator cuff surgery. However, there is controversy about myotoxic or tendinotoxic effects of local anesthetics. HYPOTHESIS: Ropivacaine administered via a subacromial pain pump would have no adverse effect on rotator cuff tendon healing, fatty degeneration, strength, or functional outcomes after arthroscopic repair. STUDY DESIGN: Cohort study; Level of evidence, 3...

Brown syndrome is characterised by impaired supraduction worse in adduction due to a restricted superior oblique tendon passing through the trochlea. A few reports have previously described Brown syndrome after upper eyelid surgery, including blepharoplasty and ptosis repair. The authors describe two additional cases of Brown syndrome following ptosis repair. The first case is a 65-year-old woman with new-onset vertical binocular diplopia following bilateral levator advancement surgery. Ocular motility examination demonstrated moderate impairment of elevation in adduction...

BACKGROUND: Basic science studies suggest that platelet-rich therapies have a positive effect on tendon repair. However, the clinical evidence is conflicted on whether this translates to increased tendon healing and improved functional outcomes. PURPOSE: To perform a systematic review of randomized controlled trials (RCTs) in the literature to ascertain whether platelet-rich plasma (PRP) or platelet-rich fibrin (PRF) improved patient outcomes in arthroscopic rotator cuff repair...

G Rahmani, J Martin-Smith, P Sullivan
Accidental self-inflicted knife injuries to digits are a common cause of tendon and nerve injury requiring hand surgery. There has been an apparent increase in avocado related hand injuries. Classically, the patients hold the avocado in their non-dominant hand while using a knife to cut/peel the fruit with their dominant hand. The mechanism of injury is usually a stabbing injury to the non-dominant hand as the knife slips past the stone, through the soft avocado fruit. Despite their apparent increased incidence, we could not find any cases in the literature which describe the "avocado hand"...

PURPOSE: To develop a clinically relevant, robust murine model of rotator cuff tendon repair to examine cellular and molecular mechanisms of healing. METHODS: Sixty C57BL/6 male mice underwent rotator cuff transection and repair using microsurgical techniques. A modified Kessler suturing technique was used prior to tendon detachment. Sutures were passed through 2 intersecting bone tunnels that were made at the tendon attachment site. Mice were sacrificed at 2 and 4 weeks with subsequent biomechanical, histologic, micro-CT, and gene expression evaluations...

We report outcomes in 29 patients with flexor tendon repairs in 32 digits (five thumbs and 27 fingers) with our modified protocols. We repaired the lacerated flexor digitorum profundus tendons with core suture repairs using the 6-strand M-Tang method and without circumferential sutures. We divided the pulleys as much as needed to allow excursion of the repaired tendons, including complete division of the A4 or A2 pulleys when necessary. In nine fingers, we repaired one slip of the flexor digitorum superficialis tendon and resected the other half...

This study compared the biomechanical performance of a novel 6-strand asymmetric flexor tendon repair with the modified Lim-Tsai technique using cyclic testing. Two groups of ten porcine tendons each were repaired and tested. Gap formation at every 100 cycles was measured. Survival was defined as maximum gap formation below 2 mm. All the repairs survived Stage I. With increased cyclic load in Stage II, the mean gap formation of modified Lim-Tsai repairs exceeded 2 mm at the 600th cycle and reached 4.2 mm (SD 1...

PURPOSE: To compare the biomechanical properties of single-row repair with triple-loaded (TL) anchor repair versus a knotless rip stop (KRS) repair in a rotator cuff repair model. METHODS: Rotator cuff tears were created in 8 cadaveric matched-pair specimens and repaired with a TL anchor or KRS construct. In the TL construct, anchors were placed in the greater tuberosity and then all suture limbs were passed through the rotator cuff as simple sutures and tied. In the KRS construct, a 2-mm suture tape was passed through the tendon in an inverted mattress fashion, and a free suture was passed medial to the suture tape to create a rip-stop...

BACKGROUND: Achilles tendon insertional sleeve avulsions occur when the Achilles distal tendon sleeve ruptures off of its insertion into the calcaneal tuberosity, sometimes with a small bony fragment from calcific tendinosis. Little evidence exists describing the outcomes and rerupture rate after operative management of Achilles tendon sleeve avulsions. METHODS: A retrospective chart review was performed to identify patients who sustained an Achilles sleeve avulsion injury treated with operative repair between October 2005 and July 2014...

BACKGROUND: Open Achilles tendon surgery with the patient in the supine position potentially avoids the complications of the prone position, but the safety and viability of the supine position for this procedure are not known. The aim of this study was to test the hypothesis that supine positioning for open repair of acute Achilles tendon ruptures would be safe, with low wound and neurologic complication rates. METHODS: Supine position safety in acute Achilles tendon repair was investigated...

James M Paci, Amanda Pawlak
Quadriceps tendon ruptures disrupt the extensor mechanism of the knee and require urgent surgical management. Traditional repair techniques have had mixed biomechanical and clinical results risking weakness and extensor lag. We describe a novel technique using tape suture and knotless anchors, which has performed superiorly during biomechanical testing and yielded terrific early clinical results.

Brianne K Connizzo, Alan J Grodzinsky
Tendinopathy is a significant clinical problem thought to be associated with altered mechanical loading. Explant culture models allow researchers to alter mechanical loading in a controlled in vitro environment while maintaining tenocytes in their native matrix. However, current models do not accurately represent commonly injured tendons, ignoring contributions of associated musculature and bone, as well as regional collagen structure. This study details the characterization of a mouse rotator cuff explant culture model, including bone, tendon, and muscle (BTM)...

BACKGROUND: Rotator cuff tears are rare injuries in adolescents but cause significant morbidity if unrecognized. Previous literature on rotator cuff repairs in adolescents is limited to small case series, with few data to guide treatment. HYPOTHESIS: Adolescent patients would have excellent functional outcome scores and return to the same level of sports participation after rotator cuff repair but would have some difficulty with returning to overhead sports. STUDY DESIGN: Case series; Level of evidence 4...

Arthroscopic repair of the long head of the biceps (LHB) is performed to treat various biceps pathologies yet the choice between tenotomy or tenodesis remains controversial. Although tenotomy is simpler and quicker, tenodesis results in fewer complications, and there are several techniques available using various fixation devices and sites. This Technical Note describes an all-arthroscopic, suprapectoral tenodesis technique using a bioresorbable interference screw, without motorized devices to create the humeral tunnel in the bicipital groove...

Kengo Harato, Shu Kobayashi, Kazuhiko Udagawa, Yu Iwama, Ko Masumoto, Hiroyuki Enomoto, Yasuo Niki
Although surgical treatment is the gold standard for chronic patellar tendon rupture, the technique of patellar tendon reconstruction is still difficult. Basically, good clinical results of surgical repair for acute patellar tendon rupture have been reported. However, the results of reconstructive surgery for chronic patellar tendon rupture are still inconsistent. Some surgical options have been previously reported. For example, surgeons need to choose between 1- and 2-stage reconstruction. Furthermore, contralateral bone-tendon-bone graft, ipsilateral semitendinosus tendon graft, Achilles tendon allograft, and an artificial ligament have been used to reconstruct the patellar tendon...

INTRODUCTION: Traumatic non-iatrogenic vascular injuries in children are rare and rarely discussed in literature. Paediatric vascular injuries pose a set of challenges mainly because of continued growth and development in a child or adolescent. The purpose of the study is to characterize management strategies and outcomes in these cases. PATIENTS AND METHODS: Single-centre retrospective review of patients less than age 18 years (paediatric age) with acute, non-iatrogenic traumatic vascular injuries between January 2009 and December 2015...

Revascularization after extremity vascular injury has long been considered an important skill among trauma surgeons. Increasingly, some trauma surgeons defer vascular repair in response to training or practice patterns. This study was designed to document results of extremity revascularization surgery to evaluate trauma surgeon outcomes and judicious referral of more complex injuries to vascular surgeons (VAS). The trauma registry of an urban level I trauma center was used to identify all patients from 2003 to 2013 who underwent an early (<24 hours) procedure for urgent management of acute injury to extremity vessels...
