Randomized Controlled Trial Comparative Study
[Comparative study on impacted high tibial osteotomy and conventional high tibial osteotomy for the treatment of flexional medial knee osteoarthritis in aged patients].
To compare the therapeutic effect of impacted high tibial osteotomy and conventional high tibial osteotomy for the treatment of flexional medial osteoarthritis of knee joint in aged patients. ⋯ Compared with conventional high tibial osteotomy, impacted high tibial osteotomy can significantly shorten the bone healing period, improve the knee flexion, varus deformity, and the knee function.

A total of 29 consecutive knee joint arthroplasties in 24 patients who underwent previous high tibial osteotomy (HTO) for medial unicompartment osteoarthritis of the knee and followed up for a mean of 97 months were compared with a control group of 28 patients with 29 primary total knee arthroplasty (TKA) without previous HTO. Results for the osteotomy group were satisfactory in 96.5% of cases. ⋯ Three patients underwent a further operation of secondary patella resurfacing for patella pain. The group without osteotomy reported a similar percentage of satisfactory results.

The decrease of patellar height following opening-wedge proximal tibial osteotomy can affect function, and subsequent total knee arthroplasty may be more difficult and give poorer results. ⋯ Retrospective, level IV.

Case Reports
[Marjolin's ulcer: malignant transformation of a crural ulcer due to posttraumatic chronic osteomyelitis].
We report on the case of an 81-year-old female patient who developed a squamous cell carcinoma in a long-lasting therapy-resistant crural ulcer of the lower leg due to posttraumatic chronic osteomyelitis. Eventually the lower leg had to be amputated because of massive destruction of soft tissue and the tibia bone. ⋯ The amputation stump had completely healed 6 months after surgery and the patient is fitted with an artificial limb ensuring independent mobility even outside the home. Up to the present there is no evidence of any tumor recurrence or progression.

Comparative Study
Facilitated tendon-bone healing by local delivery of recombinant hepatocyte growth factor in rabbits.
This study was performed to evaluate the therapeutic effect of hepatocyte growth factor (HGF) on tendon-bone healing in a rabbit model. ⋯ Application of HGF may be considered as a new therapeutic approach to accelerate healing and rehabilitation after ligament reconstruction.
