Epidural administration of ropivacaine and midazolam is superior to intra-articular administration as postoperative analgesia after isolated arthroscopic anterior cruciate ligament reconstruction with hamstrings autograft: a randomized controlled clinical trial.

Objective: Reconstructive surgery of the anterior cruciate ligament (ACL) is quite common, previous studies have documented that adequate pain control in the early phases of the postoperative period translates into early mobility and a rapid start of rehabilitation. Therefore, the search for new strategies for postoperative pain control is justified. The aim of this study was to compare intra-articular to the epidural administration of ropivacaine and midazolam as postoperative analgesia after arthroscopic ACL reconstruction with hamstring autograft (HA).

Tibial tuberosity avulsion-fracture associated with complete distal rupture of the patellar tendon: A case report and review of literature.

Background: Few cases of avulsion fractures of the tibial tuberosity with simultaneous rupture of the patellar tendon have been reported in the literature. Therefore, its mechanism and incidence have not been determined conclusively. This type of fracture is considered a serious injury that requires prompt diagnosis and early surgical repair.

Anterior cruciate ligament injuries treated with quadriceps tendon autograft versus hamstring autograft: A randomized controlled trial.

Background: One of the most common grafts used to repair anterior cruciate ligament (ACL) rupture is the hamstring tendon (HT) autograft. However, another proposed option to repair the ACL is the quadriceps tendon (QT) autograft. This study aimed to compare the pain and clinical results between patients with ACL injury treated with QT autograft and with HT autograft.

Intraarticular injection of platelet-rich plasma in knee osteoarthritis: single versus triple application approach. Pilot study.

Objective: To compare the clinical effectiveness of the triple intra-articular injection of platelet-rich plasma (PRP) with respect to the single injection in patients with mild osteoarthritis of the knee.

Methods: A total of 35 patients with a clinical and radiographic diagnosis of osteoarthritis grade I and II were analyzed. They were randomized into two groups: single application (18 patients) and triple application (17 patients).

Clinical, biomechanical and morphological assessment of anterior cruciate ligament Kevlar®-based artificial prosthesis in rabbit model.

Background: The aim of this study was to evaluate the clinical, biomechanical and morphological characteristics of a Kevlar®-based prosthetic ligament as a synthetic graft of the anterior cruciate ligament (ACL) in an experimental animal model in rabbits.

Methods: A total of 27 knees of rabbits randomly divided into 3 groups (control, ACL excision and ACL replacement with a Kevlar® prosthesis) were analyzed using clinical, biomechanical and morphological tests at 6, 12 and 18 weeks postprocedure.

Results: The mean displacement in mechanical testing was 0.
