Open reconstruction with autologous spongiosa grafts and matrix-induced chondrogenesis for osteochondral lesions of the talus can be performed without medial malleolar osteotomy.

Purpose: To evaluate complication rates and postoperative outcomes in patients with osteochondral lesions of the talus who underwent an autologous matrix-induced chondrogenesis (AMIC) procedure with autologous spongiosa grafting without malleolar osteotomy.

Methods: A total of 23 patients with a mean age of 35.6 ± 13.

Technique and results of arthroscopic treatment of posterior ankle impingement.

Background: The aim of this study was to investigate the outcome after arthroscopic procedures for treatment of posterior ankle impingement.

Methods: From June 2006 to April 2009 36 patients were treated by hindfoot arthroscopy. Indication was posterior ankle impingement due to symptomatic os trigonum or osteophytes.

[Direct posterior approach for the treatment of posteromedial tibial head fractures].

Objective: Direct posterior approach requiring minimal soft-tissue dissection for the treatment of posteromedial tibial head fractures.

Indications: Posteromedial fractures of the proximal tibia. Bicondylar tibial plateau fractures involving the posteromedial aspect of the tibial plateau.

Femoral fixation of hamstring tendon autografts using the TransFix device with additional bone grafting in an anteromedial portal technique.

Background: The femoral fixation of hamstring tendon grafts by a cross-pin is an established method with excellent biomechanical properties. Until now, this surgical procedure was associated with a transtibial placement of the femoral tunnel and a graft-tunnel diameter mismatch due to the different volumes of the tendon loop and the tendon strands.

Methods: By use of an electrical knee positioning device, the transfixation technique can be performed safely through the anteromedial arthroscopic portal (transarticular technique), reaching the optimal lateral '10:30' position in the intercondylar notch.
