Quadriceps Tendon Repair Using Double-Row Suture Anchor Fixation

ABSTRACT: Quadriceps tendon ruptures compromise the knee extensor mechanism and cause an inability to ambulate and significant functional limitations. Therefore, the vast majority of quadriceps tendon ruptures are indicated for operative intervention to restore patient mobility and function. Although these injuries were traditionally repaired using a transosseous repair technique, recent literature has shown that suture anchor repair may offer biomechanical advantages. Additionally, research in other areas of orthopaedics has found that a double-row suture anchor construct can offer additional biomechanical strength to tendinous repair. This technical note describes a safe and effective quadriceps tendon repair using a double-row suture anchor construct. Technique Video Video 1 Repair of a right quadriceps tendon rupture with the patient in the supine position. The tear is identified and mobilized, and the superior pole of the patella is prepared with a burr. Two suture anchors double loaded with suture tape (PEEK Corkscrew FT) are placed into the superior pole, and the suture ends are passed through the tendon in Krackow fashion. A double-row construct is then created using 2 sutures from the contralateral anchor and 1 from the ipsilateral anchor loaded into an additional anchor (3.5-mm PEEK SwiveLock) and impacted into the patella to create a double-row construct. This is repeated on both the medial and lateral sides of the patella. The extensor retinaculum is then repaired to complete the fixation.

Double-Row Suture Anchor Repair of Posterolateral Corner Avulsion Fractures.

Project description:Posterolateral corner avulsion fractures are a rare variant of ligamentous knee injury primarily described in the skeletally immature population. Injury is often related to a direct varus moment placed on the knee during sporting activities. Various treatment strategies have been discussed ranging from nonoperative management, to excision of the bony fragment, to primary repair with screws or suture. The described technique is a means for achieving fixation of the bony avulsion using principles familiar to double-row transosseous equivalent rotator cuff repair. Proximal anchors are placed in the epiphysis, and sutures are passed in horizontal mattress fashion. Once tied, the limbs of these same sutures are then passed to more distal anchors. Remaining eyelet sutures can be used to manage peripheral tissue. The final repair provides anatomic reduction and compression of the fragment to its bony bed with minimal extracortical hardware prominence and no violation of the physis. Risks include potential for physeal injury or chondral damage to the lateral femoral condyle through aberrant anchor placement. Postoperative care includes toe-touch weight-bearing restrictions and range of motion restrictions of 0°-90° in a hinged brace for 6 weeks followed by gradual return to activity.

Quadriceps Tendon Repair Using Knotless Anchors and Suture Tape.

Project description:Repair of a torn quadriceps tendon is necessary to restore the extensor mechanism of the knee. Traditional repair involves transosseous sutures tied over bone bridges on the inferior pole of the patella. Suture anchor repair has been shown to be stronger than transosseous repair and facilitates a smaller incision. Suture tape can improve the strength of the suture-tendon interface, and when combined with knotless anchors, leads to a stronger repair construct than even traditional suture anchors and surgeon-tied knots. Here we describe our technique of quadriceps tendon repair using suture tape and knotless anchors.

Arthroscopic Double-Row Suture Anchor Repair of Acute Posterior Bony Bankart Lesion.

Project description:The treatment of anterior shoulder instability is well described with various techniques, including arthroscopic double-row repair, an alternative to open stabilization procedures in high-risk groups. The surgical management of posterior instability in high-risk and athletic populations is a less-explored entity. We describe our technique for an all arthroscopic double-row suture anchor repair of a large posterior bony Bankart lesion. We prefer this technique over percutaneous cannulated screw fixation because the double-row suture technique allows for incorporation of capsular plication with bony fixation in an effort to better restore normal anatomy for capsulolabral complex. Double-row repair capsulolabral repair or fixation of the bony Bankart is performed via a suture-bridge technique. Medial row anchors are placed down the glenoid neck and shuttled around the bony fragment and labrum. The lateral-row anchor is placed at the rim of the native glenoid. This repair technique has been shown to increase the surface area for healing and more closely reconstruct the native anatomic capsulolabral complex footprint, improve force distribution, and potentially impart enhanced posterior stability to the glenohumeral joint.

Biomechanical Testing of Suture Anchor Versus Transosseous Tunnel Technique for Quadriceps Tendon Repair Yields Similar Outcomes: A Systematic Review.

Project description:PurposeTo systematically review the literature to evaluate the biomechanical properties of the suture anchor (SA) versus transosseous tunnel (TO) techniques for quadriceps tendon (QT) repair.MethodsA systematic review was performed by searching PubMed, the Cochrane Library, and Embase using PRISMA guidelines to identify studies that evaluated the biomechanical properties of SA and TO techniques for repair of a ruptured QT. The search phrase used was "quadriceps tendon repair biomechanics". Evaluated properties included ultimate load to failure (N), displacement (mm), stiffness (N/mm), and mode of failure.ResultsFive studies met inclusion criteria, including a total of 72 specimens undergoing QT repair via the SA technique and 42 via the TO technique. Three of 4 studies found QTs repaired with SA to have significantly less elongation upon initial cyclic loading when compared to QTs repaired with the TO technique (P < .05). Three of 5 studies found QTs repaired with SA to have significantly less elongation upon final cyclic loading when compared to QTs repaired with the TO technique (P < .05). The pooled analysis from 4 studies reporting on initial displacement showed a statistically significant difference in favor of the SA group compared to the TO group (P = .03). The pooled analysis from studies reporting on secondary displacement and ultimate load to failure showed no significant difference between the SA and TO groups (P > .05). The most common mode of failure in both groups was suture slippage.ConclusionOn the basis of the included cadaveric studies, QTs repaired via the SA technique have less initial displacement upon cyclic testing when compared to QTs repaired via the TO technique. However, final displacement and ultimate load to failure outcomes did not reveal differences between the two fixation strategies. Knot slippage remains a common failure method for both strategies.

Suture Anchor Repair With Fully Threaded Knotless Anchors for Quadriceps Tendon Rupture Resulted in Favorable Outcomes After 2 Years.

Project description:PurposeTo investigate clinical outcomes over 2 years in cases of quadriceps tendon rupture (QTR) that were surgically treated using fully threaded knotless anchors.MethodsA total of four knees in four male patients with QTR repaired with fully threaded knotless anchors at our hospital from November 2017 to January 2019 were enrolled. Mean patient age at surgery was 65.3 years (range: 61-70 years). Intraoperatively, stability of the sutured site was confirmed by knee flexion to 90°. Full weight walking with the orthosis in extension was commenced on the seventh postoperative day. Surgical findings, pathologies of the ruptured quadriceps tendons, and postoperative clinical outcomes were evaluated in all patients.ResultsThe QTR was complete in three cases and partial in one. Average surgical duration was 58.5 (range: 49-74) minutes. Pathological evaluation revealed hyaline degeneration with granulation of the quadriceps tendon in two cases. No complications, such as infection and rerupture, occurred. Magnetic resonance imaging performed 1 year postoperatively confirmed complete healing of the repaired tendon. The mean follow-up period was 35.5 months (range: 24-46 months). None of the patients had extension lag of the knee, and mean Lysholm score and range of flexion were 95.3 (range: 85-100) and 141.3° (range: 140-145°), respectively, at the final follow-up.ConclusionsClinical outcomes were favorable in all cases, including two cases with pathological degenerative changes. Suture anchor repair with fully threaded knotless anchors can be considered a minimally invasive and effective method for QTR, with sufficient strength to allow early rehabilitation.

Open Repair of Quadriceps Tendon With Suture Anchors and Semitendinosus Tendon Allograft Augmentation.

Project description:Quadriceps tendinopathy in an increasingly recognized diagnosis can lead to quadriceps tendon rupture, especially in the older population. It can be caused by repeated micro trauma or also predisposed by systemic diseases such as diabetes mellitus and connective tissue disorders that can in turn lead to extensor mechanism deficits. Although a trial of conservative treatment is advocated, operative treatment should be performed in cases of persistent pain, extension deficit, or complete rupture of the tendon. The purpose of this Technical Note is to describe in detail a procedure for open repair of a quadriceps tendon, with significant degeneration due to quadriceps tendinopathy, using suture anchors and semitendinosus tendon allograft augmentation.

Suture Bridge Transosseous Quadriceps Tendon Repair for Spontaneous Quadriceps Tendon Rupture in Patients With End-Stage Renal Disease.

Project description:End-stage renal disease with spontaneous quadriceps tendon rupture (QTR) is a specific condition that differs from classic QTR. The tissue quality of the quadriceps tendon (QT), the rupture site, the mechanism of injury, and the pathophysiology of the rupture mechanism all have an effect on conventional QT repair procedures, with a higher likelihood of rerupture or failed repair construction. We believe that our technique provides repair-site stability, strong repair construction, increased contact surface healing, and a reduced chance of rerupture after QT repair. Furthermore, in most patients who have end-stage renal disease with QTR, misdiagnosis and/or underestimation occurs, resulting in proximal retraction of the QT and poor results; however, this technique can be performed with alternative procedures such as augmentation or QT lengthening. The suture bridge transosseous QT repair technique relies on biomechanics knowledge for better stability. Suture bridge repair concept can achieve better healing of all layers of the QT until returning to normal activity with no disability and an improved quality of life.

Gluteus medius repair with double-row fixation.

Project description:The merits of double-row tendon fixation have been well defined in the shoulder and may have greater applicability for gluteus medius tears in the hip, in which protection of the repair site can be even more of a challenge because the hip is a weight-bearing extremity. A detailed technique for double-row fixation with a reliable method and implants is highlighted in the accompanying stepwise-approach video. Standard laterally based peritrochanteric portals are used, including a viewing portal posterior to the vastus lateralis ridge and a working portal distal to the ridge, with anchors placed proximally, perpendicular to the cortex of the trochanter. Proximal fixation is accomplished with double-loaded Healicoil anchors (Smith & Nephew, Andover, MA) by use of sutures placed in a mattress fashion. Distal fixation is accomplished with a Footprint anchor (Smith & Nephew) paired to each Healicoil.

Arthroscopic Suture Bridge Anchor Repair of Comminuted Greater Tuberosity Fracture With Double-Row Biceps Tenodesis in Elderly Osteoporotic Patients.

Project description:Isolated greater tuberosity fractures with displacement require usually open reduction and fixation to prevent poor outcomes, but high levels of morbidity have been reported. Recently, newer techniques describe arthroscopic fixation of greater tuberosity fracture for young patients; however, in elderly patients with comminuted osteoporotic fractures, this entity is more complex. A new arthroscopic technique is described through a minimally invasive approach that allows the evaluation of the glenohumeral joint and the treatment of associated pathology. These comminuted fractures can be treated using suture bridge technique. Postoperatively, rehabilitation consists of a similar regimen to that of a rotator cuff repair. With the appropriate surgical technique, good clinical outcomes can be obtained.

How to Maximize Suture Tension in Double-Row Suture-Bridge Rotator Cuff Repair?

Project description:Double-row suture-bridge technique for rotator cuff repair has been used for rotator cuff tears. In large tears that require 2 or more lateral row anchors, loosening of the suture bridges could occur because of tightening sequence. By retightening suture limbs before deploying the first lateral row anchor, premature loosening could be prevented and enhance the tension of the construct.
