Tibial Fixation Properties of a Continuous-Loop ACL Hamstring Graft Construct with Suspensory Fixation in Porcine Bone

J Knee SurgDOI: 10.1055/s-0034-1394167The aim of this article is to compare tibial fixation strength of suspensory fixation for a quadrupled semitendinosus continuous loop all-inside anterior cruciate ligament (ACL) construct versus a doubled semitendinosus and gracilis graft fixated with an interference screw. Biomechanical testing was conducted using human hamstring allografts and porcine tibias. Constructs were cycled from 50 to 250 N for 500 cycles followed by a pull to failure. The average load to failure of tibial suspensory fixation of the all-inside continuous loop construct (1,012 N) was statistically different compared with the tibial interference screw group (612 N) (p

AbstractPurposeTo study the effect of age, duration of injury, type of graft and concomitant knee injuries on return to sports after anterior cruciate ligament (ACL) reconstruction.MethodOne-hundred and sixteen athletes underwent ACL reconstruction using either bone –patellar tendon–bone graft (BPTB;n = 58) or semitendinosus-gracilis graft (n = 58), depending upon their random number sequences. Five variables were analyzed in terms of their effect on return to sports-age, type of graft, time interval between injury and surgery, chondral damage and meniscal tears.ResultsFifty-three ou...

Anterior cruciate ligament (ACL) rupture is one of the most common types of knee joint sports injury. Patients with a rupture of the ACL may lead to swelling, pain, instability, mechanical dysfunction, and non-surgical treatment will also increase the risk of further meniscus injury and degenerative joint disease [1,2]. The most frequently used auto-grafts for ACL reconstruction (ACLR) are bone-patellar tendon-bone (BPTB) and four-strand hamstring tendon (4S-HT), but significant controversy exists about which graft is better.

AbstractThe anterolateral ligament (ALL) and capsule of the knee are anatomical structures involved in rotational stability and pivot-shift control. As such, it has been demonstrated that the extra-articular anterolateral procedures improve clinical outcome when performed as an augmentation of the anterior cruciate ligament (ACL) reconstruction in specific groups of patients. This review describes the postoperative imaging findings of two techniques used to perform these procedures, using magnetic resonance imaging (MRI), computed tomography (CT), and radiography. The first technique described is the lateral extra-articula...

This study aimed to assess the clinical and radiographic outcomes of BPTB and gracilis (G) composite autografts for primary double-bundle ACL reconstruction in Asian athletes. Thirty-two Asian patients undergoing double-bundle ACL reconstruction with 7.0 to 7.5 mm of BPTB and 5.0 to 5.5 mm of G composite grafts were compared with 43 double-bundle ACL reconstruction with hamstring graft cases. The BPTB graft was used for the anteromedial bundle (AMB), with the G graft for the posterolateral bundle (PLB). Percentage of femoral bone tunnel enlargement compared with the original size was determined by computed di...

Authors: Sevimli R, Gormeli G, Polat H, Kilinc O, Turkmen E, Aslantürk O Abstract AIM: The present study investigates time until revision and revision rates, and their relationship with gender and age, among 267 patients with anterior cruciate ligament tears treated with autograft and allograft reconstructions. MATERIALS AND METHODS: A retrospective evaluation was carried out based on data collected on 269 knees (bone-patellar tendon-bone autograft in 25, gracilis-semitendinosus autograft in 136, quadriceps autograft in two, allograft in 106) belonging to 267 patients who underwent an anterior cruciate lig...

Authors: Hunnicutt JL, Slone HS, Xerogeanes JW Abstract The quadriceps tendon (QT) has become increasingly used by orthopaedic surgeons as an alternative autograft choice in anterior cruciate ligament reconstruction. As its use increases, athletic trainers and other rehabilitation clinicians will treat a greater number of patients with this autograft type. The recently developed, minimally invasive technique for harvest of the all-soft tissue autograft has many benefits, including versatility, decreased donor-site morbidity, and enhanced cosmesis. Early clinical trials revealed that the QT autograft resulted in dec...

J Knee Surg DOI: 10.1055/s-0040-1702164The ideal procedure for anterior cruciate ligament (ACL) reconstruction is one that can achieve anatomical restoration for a better ACL function. This retrospective comparative study was conducted to evaluate the objective and subjective clinical results of the conventional single-bundle femoral round (SBR) tunnel technique, the single-bundle femoral oval (SBO) tunnel technique, and the double-bundle (DB) surgical technique for anatomical ACL reconstruction with hamstring tendon autografts. Patients who underwent the SBO, SBR, and DB ACL reconstructions from January 2016 to August 201...

ConclusionsSeptic arthritis following ACL reconstruction can be significantly reduced (or even eliminated) by soaking ACL autografts in a 5  mg/ml vancomycin solution. Of note, this strategy seems to be more effective in the setting of hamstring tendon autograft use, since the risk of postoperative knee infection is significantly higher when this type of graft is used.
