Femoral tunnel position on conventional magnetic resonance imaging after anterior cruciate ligament reconstruction in young men: transtibial technique versus anteromedial portal technique.

Purpose: The purpose of this study was to compare clinical outcomes after single-bundle anterior cruciate ligament (ACL) reconstruction with a free Achilles tendon allograft using either a transtibial or an anteromedial portal technique and then to quantify the difference in femoral tunnel position between these 2 approaches. This assessment was to be performed with a new method using conventional magnetic resonance imaging (MRI) with a digital imaging system.

Methods: In this prospective randomized comparative study, 53 young male patients with ACL rupture underwent ACL reconstruction with the transtibial technique (group 1) or the anteromedial portal technique (group 2).

Single-bundle anterior cruciate ligament reconstruction in active young men using bone-tendon achilles allograft versus free tendon achilles allograft.

Purpose: The purpose was to prospectively compare the outcomes of anterior cruciate ligament (ACL) reconstruction using bone-tendon Achilles allograft with those of free tendon Achilles allograft in 2 groups of active young men.

Methods: We enrolled 72 subjects in the study. Of these, 33 subjects who had ACL reconstruction with Achilles allograft with calcaneal bone block on its end (group I) and 34 who had ACL reconstruction with free tendon Achilles allograft (group II) were followed up for a minimum of 2 years.

Outcomes of operative treatment of unstable ankle fractures: a comparison of metallic and biodegradable implants.

Background: Biodegradable implants for internal fixation of ankle fractures may overcome some disadvantages of metallic implants, such as imaging interference and the potential need for additional surgery to remove the implants. The purpose of this study was to evaluate the outcomes after fixation of ankle fractures with biodegradable implants compared with metallic implants.

Methods: In this prospectively randomized study, 109 subjects with an ankle fracture underwent surgery with metallic (Group I) or biodegradable implants (Group II).

Hybrid tibial fixation for anterior cruciate ligament reconstruction with Achilles tendon allograft.

Purpose: To compare clinical outcomes of tibial fixation between a biodegradable interference screw only and a biodegradable interference screw supplemented by a post-tie using a washer screw in single-bundle anterior cruciate ligament (ACL) reconstruction with 2-strand free tendon Achilles allograft in active young men.

Methods: A prospective study was performed in 80 subjects who underwent single-bundle ACL reconstruction. A 2-strand free tendon Achilles allograft fixed with an EndoButton (Smith & Nephew, Andover, MA) in the femoral tunnel and with a Bio-Interference screw (Arthrex, Naples, FL) in the tibial tunnel was used in group I.

Anterior cruciate ligament reconstruction using 4-strand hamstring autograft: conventional single-bundle technique versus oval-footprint technique.

Purpose: The purpose of this study was to compare short-term results of conventional anterior cruciate ligament (ACL) reconstruction with oval-footprint (modified) single-tunnel ACL reconstruction with 4-strand hamstring autograft.

Methods: A prospective comparative study was performed in 74 consecutive subjects who underwent ACL reconstruction with the conventional technique (group I, 40 cases) or the modified technique (group II, 34 cases), in which the entrances of the femoral and tibial tunnels were more elongated, by use of 4-strand hamstring tendon. The Lachman test, pivot-shift test, range of motion, International Knee Documentation Committee classification, Lysholm score, and side-to-side differences were evaluated preoperatively and at the last follow-up.

Synovialization on second-look arthroscopy after anterior cruciate ligament reconstruction using Achilles allograft in active young men.

Purpose: This study is to assess the relationship between clinical outcomes and the extent of synovialization through second-look arthroscopy for anterior cruciate ligament (ACL) reconstruction using Achilles allograft in active young men.

Methods: Ninety-five subjects were diagnosed with ACL rupture and underwent reconstruction with Achilles allograft. Median age was 22 years old (range, 17-40).

Outcome of the functional treatment of first-time ankle inversion injury.

Background: Avulsion fractures of the lateral malleoli in ankle inversion injuries are often undetected on routine radiographs. Undetected avulsion fractures have been managed as ankle sprain, which may affect the outcome of the treatment of the ankle sprain. The purposes of this study are to compare the outcomes of functional treatment between the first-time severe ligament injury and avulsion fracture of the lateral ankle, and to investigate how the anterior talofibular ligament (ATFL) view or the calcaneofibular ligament (CFL) view affects the diagnosis of the avulsion fracture and outcome of functional treatment of the ankle inversion injury.
