Effects of microendoscopy-assisted reduction and screw fixation through a single mini-incision on posterior cruciate ligament tibial avulsion fracture.
There are various surgical approaches for the treatment of posterior cruciate ligament (PCL) injury-associated tibial fracture avulsion, including arthroscopy-assisted surgery and open posterior surgery. However, none of these treatments are perfect. We have established a simple procedure with microendoscopy-assisted reduction and cannulated screw fixation for the treatment of this disease through a single mini-incision. In this study, we delineated the effects of this surgical approach for patients with PCL tibial avulsion fracture. ⋯ Increased stability, functional improvement, and few complications were observed in patients of PCL injury-associated tibial fracture avulsion treated with the microendoscopy-assisted reduction and cannulated screw fixation through a single mini-incision.

Tibial tubercle advancement osteotomy with bone allograft for patellofemoral arthritis: a retrospective cohort study of 50 knees.
Forty consecutive patients (21 females and 19 males) in a single centre underwent 50 tibial tubercle advancement osteotomy procedures for patellofemoral arthritis between January 1993 and April 2007. Twenty knees with patellar maltracking also underwent medialisation of the tibial tubercle (6-12 mm) in addition to the standard 10-15 mm elevation. Femoral head bone allograft blocks were utilised in all cases, and all patients achieved bony union without further surgery. Forty-five knees had previously undergone arthroscopy, 18 with arthroscopic lateral releases. ⋯ Tibial tubercle advancement osteotomy can be an effective treatment for anterior knee pain and for patients with arthroscopic evidence of patellar chondral damage. It can provide excellent/good long-term functional results in the majority of patients, with very high satisfaction levels and sustained improvement in pain symptoms. The use of femoral head bone allograft is both effective in obtaining bony union and by definition avoids the donor-site morbidity. Knees with patellar malalignment may also undergo individualised medialisation of the tibial tubercle such that the patella lies in the centre of the femoral trochlea, and may benefit from lateral trochleaplasty surgery in the presence of trochlear dysplasia. However, the major operative complication rate is high at 12%, and fracture of the tibial tubercle is associated with a poorer outcome. One can expect 10% of operated knees to have had some clinical deterioration in the patellofemoral joint by a mean follow-up of 93 months.

Virtual Bernese osteotomy using three-dimensional computed tomography in hip dysplasia.
Accurate assessment of acetabular morphology and its relationship to the femoral head is essential for planning a periacetabular osteotomy. We observed the acetabular coverage after virtual Bernese osteotomy using computer-aided technique. ⋯ Computer-aided virtual surgery technique based on three-dimensional computed tomography information enabled acetabular coverage to be quantified preoperatively in Bernese osteotomy. Lateral rotation of osteotomized acetabular fragments improved anterior and posterior coverage as well as lateral coverage.

Clinical characteristics and surgical outcome of the symptomatic ossification of ligamentum flavum at the thoracic level with combined lumbar spinal stenosis.
Retrospective study. ⋯ Thoracic OLF with LSS will show a more severe clinical manifestation than that without LSS. In this study, we clearly indicated that the coexisting LSS in thoracic OLF will have adverse effects on the surgical results in thoracic OLF.

Single-stage anterior debridement and fusion with autografting and internal fixation for pyogenic lumbar spondylodiscitis.
Patients with pyogenic lumbar spondylodiscitis can be successfully treated by non-operative methods. However, the typical operation for this condition includes debridement of the infected site, bone grafting and internal fixation to stabilize the spine. Single-stage anterior debridement and fusion with autografting and internal fixation of one spinal segment were performed on nine patients with pyogenic lumbar spondylodiscitis. This operative procedure is rarely documented for pyogenic lumbar spondylodiscitis. ⋯ Based on the limited population studied, it suggested that this technique may be a safe and effective operative procedure for appropriate pyogenic lumbar spondylodiscitis in patients.
