[The distally based adipofascial sural artery flap for the reconstruction of distal lower extremity defects].
Problematic tissue defects in the distal one-third of the lower leg represent a special challenge for the operative therapy. The distally based adipofascial sural artery flap is a safe and effective modification of the classical fasciocutaneous sural artery flap technique and makes the reconstruction in this problematic area more feasible. The surgical aim is soft tissue reconstruction with local tissue avoiding free tissue transfer. ⋯ Between 1997 and 2012, this technique was used in 104 consecutive patients with soft tissue defects in the distal one-third of the lower leg. Flap survival was achieved 91 patients. In 2 patients amputation of the lower leg was necessary at the mid tibia level. In 3 cases flap necrosis occurred, requiring free tissue transfer.

Soft tissue defect reconstruction by transposition of well-vascularized muscle tissue with a muscle flap and as an osteomuscular flap together with a fibular bone segment for combined skeletal and soft tissue defects. ⋯ Reliable, excellent functional and aesthetic results with very low donor site morbidity.

Replacement of full thickness soft tissue defects in the lower leg and ankle, appropriate to the defect and following the course of blood vessels feeding the skin of a distally hinged fasciocutaneous flap most reliably based on the individual anatomy of distal perforators of the posterior tibial artery. ⋯ Retrospective uncontrolled study with over 70 saphenous perforator flaps from 1995-2011. Full soft tissue defects 62 times with osteomyelitis, 3 times with endoprothesis, 3 times with fractures, 2 times with exposed tendons. From 1995-2006, 44/50 (88 %) flaps healed completely or at least to 3/4 without the necessity of further flaps; from 2007-2011, 13/20 (65 %) flaps healed completely and 6/20 (30 %) flaps healed at least to 3/4 without the necessity of further flaps, loss of one flap (5 %).

[Anatomic reconstruction of the anterior cruciate ligament in single bundle technique].
Restore the knee stability by ACL reconstruction of the anterior cruciate ligament. ⋯ In a prospective study, we have examined 21 patients treated with an anatomic anterior cruciate ligament reconstruction in single-bundle technique, after two years. As graft the semitendinosus was used. The postoperative MRI diagnosis showed that all tunnels were positioned anatomically. KT 1000 measurement showed that the difference of anterior translation decreased from an average of 6.4-1.7 mm. A sliding pivot shift phenomenon was detected in only one patient. The postoperative Lysholmscore was 94.2 points.
