Synovial Elevator - AR-8853 SN# 152018. The coring reamer system is designed to harvest a cylinder of cancellous bone while simultaneously creating the tibial tunnel. to harvesting the hamstring tendons. The harvested bone core can then be used to fill the patellar tendon harvest site, pack into bone funnels construct a bone-hamstring tendon-bone autograft, or bone graft opening wedge HTO procedures. Purpose: The purpose of this study was to determine if there was a difference in the clinical results of anterior cruciate ligament (ACL) reconstruction when using the semitendinosus tendon (ST) alone versus the semitendinosus and gracilis (STG) construct. Thereby, a spongy bone plug approximately 6 mm in diameter and 25–28 mm in length was harvested (Fig. 7 An additional advantage of the QT graft is a more dependable graft size: As is the case with the BPTB graft, the surgeon can select … Knee Surg Sports Traumatol Arthrosc (2010) 18:1625 DOI 10.1007/s00167-010-1241-y LETTE R T O T HE EDI T ORS Augmentation of autologous hamstring graft during anterior cruciate ligament reconstruction using the bone chip technique … Traditional bone-patellar tendon-bone and hamstring tendon ACL grafts are not without limitations. Hamstring curls ... Measure thickness at midsagital patella and 3 cm proximal to the proximal pole. Partial thickness harvest is preferred (tendon thickness >8 mm) to full thickness ... With firm tension on the sutures, use the Arthrex stripper/cutter to strip the tendon proximally and to the desired graft length. Minimally invasive approaches are one of the many advantages to the quad tendon graft. For a less invasive option, harvest the tendon using the minimally invasive hamstring harvest technique and instruments described in technique guide LT0124. During hamstring harvest, ... (Arthrex) suture and sized for the typical 5-mm to 6-mm diameter of doubled graft. The aim of this study is to evaluate results of anterior cruciate ligament reconstruction (ACL) using an All-Inside Full Thickness Quadriceps Reconstruction technique at 5 years follow up. The 6-strand hamstring tendon graft was significantly stiffer compared with the quadriceps tendon (1147.65 vs 808.65 N/mm; P¼ .04). Arthroscopy and Sports Medicine. Once fixation at the femoral and tibial tunnels is complete, the knee is taken through a full range of motion, while the Lachmann and Pivot-Shift tests are performed to verify proper reconstruction.

Graft Harvesting Retractor AR-1420 CENTERING CYLINDERS Centering Cylinders provide a simple alternative to collared pins in conjunction with Coring Reamers to harvest a round bone graft when creating the tibial tunnel during ACL reconstruction, without removing the tibial guide pin. The drill footprint was used to guide a 7-mm rounded tube harvester (AR-1980-07, OATS® Set, Arthrex) into the femur, which was advanced 30 mm, rotated and extracted. Minimally Invasive Graft Harvesting Set (AR-1279S) Obesity, misalignment, physical inactivity as well as sports injuries can lead to joint problems and restricted movement. drilling the tibial tunnel or harvesting hamstring tendons. Conclusion: The 6-strand hamstring tendon and quadriceps tendon graft had similar biomechanical properties with respect to ultimate load to failure and load at 3 mm of displacement in 6 matched cadaveric specimens. Both the kneecap and the hamstring are critical to normal knee function, and damaging these structures can cause problems with rehabilitation. Arthrex – Hamstring Donor Site Delivery Tube with Anterior Hamstring Harvest. The aim of this study was to compare the biomechanics of a four-strand hamstring graft with a tripled semitendinosus graft, with and without adjustable extra-cortical button fixation, in a cadaveric model. 152 views.

One of the issues with a small incision is assuring appropriate proximal closure. FEATURING Mirco Herbort , Robert Smigielski , Abermann Elisabeth , Christian Fink , Rainer Siebold. The QT graft was introduced in 1979 by Marshall et al. Hamstring harvest. Abstract. While graft harvesting is done in a way to minimize collateral damage, some people want to avoid this altogether. ARTHREX: AR-1229S. The distal tunnel should be drilled up to a depth of 10 mm, with a cannulated drill that is 1 mm larger in diameter than the selected coring reamer, prior to collared pin insertion. The gracilis tendon is often used as an autograft for ligament or tendon reconstruction. A marking pen is also used to identify the superior pole of the patella on the QT and the medial border of the planned QT harvest, leaving a 1- to 2-mm cuff of tendon between the graft and the VMO. After the examination under anesthesia, a padded ... Arthrex) is used to release each tendon from its prox-imal musculotendinous attachment. The ACL-reconstruction quadrupled hamstring graft involves tensioning the graft before final suturing of the construct. Semitendinosus hamstring tendon harvest for ACL reconstruction through a single posterior incision harvest technique from a left knee, with the foot to the right and the hip to the left. With the knee at 90° of flexion, the Arthrex (Naples, FL) triple-blade harvest knife is used to incise the tendon starting just proximal to the superior pole of the patella, advancing toward the musculotendinous junction of the rectus femoris, which is identified by the mark previously placed on the anterior skin (Fig. arthrex transtibial acl reconstruction system for btb grafts probe, hook 3.4mm tip w/5mm ma insert 2.4 mm obturator, 3.5 mm drill, 8mm cannulated drill, 9mm cannulated drill, 10mm cannulated drill, 11mm cannulated guide sleeve, parallel 2.4mm p offset drill guide, 3.5mm offset drill guide, pin, 3.5mm tunnel plug stripper semitendinosus, 7mm Hamstring Harvest and Graft Preparation. 12.8). This is a Retrospective cohort study of patients undergoing ACL reconstruction. Many minimally invasive techniques can now be performed in joint surgery thanks to modern arthroscopy. Femoral fixation was secured by transfixion (Transfix; Arthrex, Naples, CA) and tibia fixation by a biodegradable interference screw and 2 staples. 11 A recent systematic review revealed that the QT graft had knee stability, functional outcomes, and rerupture rates comparable with HT and BPTB but decreased rates of numbness and anterior knee pain. An Arthrex 9-, 10-, or 11-mm parallel quadriceps harvest … Semitendinosis Harvesting and GraftLink Preparation In most cases only the semitendinosis is needed to create the GraftLink construct. Significant hamstring strength deficits at low and high speed after harvest for ACL reconstruction were present at 6 months. The quad tendon has increasingly became a very common option for anterior cruciate ligament reconstruction. The purpose of this study is to clinically evaluate hamstring tendon anterior cruciate ligament (ACL)-reconstruction using femoral fixation with bioresorbable interference screws and with a bioresorbable transfixation device. There is no difference between quadriceps- and hamstring tendon autografts in primary anterior cruciate ligament reconstruction: A 2-year patient-reported outcome study. Dilator, Small - AR-8851 SN# 3420839. 2a). A growing body of anatomic, biomechanical and clinical data has demonstrated the utility of quadriceps tendon autograft in arthroscopic knee ligament reconstruction. Type of study: Prospective randomized study. Dilator, Large - AR-8852 SN# 3420839. While maintaining the knee in this position, the hamstring autograft is fixed into the tibial tunnel using a 9 × 25-mm bioabsorbable interference screw (Arthrex) . Although hamstring strength improved at 1 year, it was still significantly less at low speeds.Figure 5 is at 1 year showing persistent atrophy in the semitendinosus and gracilis. ARTHREX AR-3030AW HD Endoscope, 30°, 4 x 177 mm, Storz Style. Centerline Endoscopic Carpal Tunnel Release System - AR-8850S. Augmentation of autologous hamstring graft during anterior cruciate ligament reconstruction using the bone chip technique. The purpose of the study was the histological examination of tendon-bone healing of hamstring grafts after anterior cruciate ligament (ACL) reconstruction. ACL Reconstruction Using a Ribbon Like Graft, Rectangular Femoral Tunnel and C-shaped Tibial Bone Tunnel. trajectory of planned QT harvest. ACL Reconstruction with Hamstring Tendon Transportal Technique Using Arthrex Tightrope. Between 3 and 20 months after surgery, we performed 12 hamstring tendon biopsies (in 9 men and 3 women; mean age, 29 years). Knee Surg Sports Traumatol Arthrosc, 26 (2018), pp. Centerline Endoscopic Carpal Tunnel Release Instrument Case - AR-8850DC. During five arthroscopies done 6–14 months after ACL reconstructions, biopsies of the wall of the former drilled femoral canal were obtained. 605-614. The graft is wrapped in saline-soaked sponge. Tal S. David, MD, (San Diego, CA) demonstrates how the Hamstring Donor Site Block Delivery Tube is used to deliver a bolus of medication to a hamstring harvest site for pain management. 1. choose to harvest a hamstring tendon (gracilis or semitendi-nosus) from either the ipsilateral leg or contralateral leg, similar to an anterior cruciate ligament reconstruction (ACLR).1,28 The ipsilateral leg is commonly known as the drive or lag leg while the contralateral leg is known as the landing or lead leg. Therefore, the Fig 1. ST & G tendon prepared with internal bracing done using fibretape .
