Comparative Study
No difference in tibial lengthening index by use of Taylor spatial frame or Ilizarov external fixator.
Different methods and devices are used to perform lengthening and deformity reconstruction in the tibia. Recently, the Taylor spatial frame (TSF) has been introduced as a computer-assisted and versatile external ring fixator. Lengthening index (LI) and complications are important result parameters, and the aim of this study was to review our first 20 tibial segments operated with the TSF and to compare the results with our experience of using the traditional Ilizarov external fixator (IEF). ⋯ We found no difference between the TSF and IEF frames regarding LI and complication rate. However, rotational, translational, and residual deformity correction is easier to perform with the TSF.

Altering the tibial slope in an anterior cruciate ligament-deficient knee has been shown to affect anterior-posterior tibial translation. The effects on articular contact pressure of altering tibial slope during a high tibial osteotomy are unknown. ⋯ In knees with chronic anterior cruciate ligament deficiency, posteromedial compartment degeneration is observed. Inadvertent redistribution of contact pressure into this area may be a cause of pain and premature clinical failure after medial opening wedge tibial osteotomy.

Case Reports Comparative StudyMedial fibula transport with the Ilizarov frame to treat massive tibial bone loss.
Massive segmental tibial bone loss from trauma, tumor, or infection is a limb-threatening situation. It is a considerable surgical challenge, especially when associated with extensive skin and soft tissue damage. Amputation was the only solution in the past, but current limb-salvage options include contralateral or ipsilateral microvascularized or free-fibular transfer. However, these methods are not without risks and disadvantages. We report seven patients with massive tibial bone loss treated by gradual medial transport of the ipsilateral fibula using an Ilizarov traction apparatus with olive wires after proximal and distal fibular osteotomies. This method has the advantages of avoiding surgery on the contralateral limb while allowing early weightbearing because of the stability of the Ilizarov frame. Hypertrophy of the transported fibula accompanied by full weightbearing and satisfactory joint motion occurred in all patients. All patients were satisfied with the results, and none thought amputation would have been a better treatment. The minimum followup was 5 years. We think the Ilizarov frame for ipsilateral fibular gradual transport is a reasonable alternative for limb salvage in patients with massive tibial bone loss. ⋯ Therapeutic Study, Level IV (case series).

Medial hemisoleus muscle flap: a reliable flap for soft tissue reconstruction of the middle-third tibial wound.
Although the medial hemisoleus muscle has been considered a local reconstructive option for soft-tissue reconstruction of the middle-third tibial wound, its reliability and usefulness has been debated among plastic surgeons. This study reports one surgeon's experience with medial hemisoleus muscle flaps and shows their application for soft tissue reconstruction of middle-third tibial wounds. Over the past 2 years, 10 patients underwent soft tissue reconstruction of a middle-third tibial wound with a medial hemisoleus muscle flap and skin graft. ⋯ The tibial wounds of all patients subsequently healed with excellent cosmetic outcome during follow-up. The results from this study indicate that the medial hemisoleus muscle flap is reliable for soft-tissue reconstruction of a middle-third tibial wound. Meticulous flap elevation with the preservation of perforators to the flap is the key for such success.

Limitations to the range of motion of the knee reduce knee function and life quality. Flexion deficits inhibit using stairs and shoe closure, and may cause social deprivation. We present a pathophysiological concept of arthrolysis of the knee for flexion deficit. Our concept divides into intra- and extra-articular factors involving knee stiffness. Extra-articular problems can be located proximally in the quadriceps mechanism and distally in the patellar tendon. ⋯ A strict postoperative protocol is obligatory for pain control and physiotherapy. In 19 cases treated with this algorithm there was a mean flexion gain of 26 degrees. The AOSSM subjective outcome score was excellent in ten and good in seven cases after a mean follow-up of 8.2 months. This treatment protocol allows improvement in flexion, even in difficult revision cases.
