Comparative evaluation of posterior cruciate ligament in total knee arthroplasty.
It has been realized that for osteoarthritis (OA) knee with varus deformity, posterior cruciate ligament (PCL) release resulted in the increase of the flexion gap without significant effect on the extension gap. While the effect of release on gap angle is still obscure. On the other hand, gap distance and varus angle measured under different distraction forces suggest different patterns. ⋯ Our study indicated that the sacrifice of PCL will decrease the varus deformity at both extension and flexion, but with the exception under low distraction force at flexion. A proper distraction tension is of great importance in gap balancing during TKA. Sufficient attention of varus differences should be paid to the gap balance technique when choosing from different techniques, PCL-retained TKA or PCL-sacrificed TKA, as well as and an appropriate distract tension during measurement.

Randomized Controlled TrialUse of tranexamic acid in dynamic hip screw plate fixation for trochanteric fractures.
To evaluate perioperative blood loss and blood transfusion requirement in patients who underwent dynamic hip screw plate fixation for a stable trochanteric fracture with or without preoperative intravenous tranexamic acid (TXA). ⋯ TXA is safe and effective in reducing blood loss in dynamic hip screw plate fixation for stable trochanteric fractures.

Acetabular revision with bone grafting and cementation for aseptic loosening after primary Charnley low-friction hip arthroplasty with structural bulk autografts.
To review the outcome of acetabular revision with bone grafting and cementation for aseptic loosening after primary Charnley low-friction hip arthroplasty with structural bulk autografts in 15 patients. ⋯ The medium-term outcome of acetabular revision with bone grafting and cementation is satisfactory. Repeat bone grafting is required to restore the anatomic acetabular position and bone loss secondary to acetabular loosening.

Frequent small distractions with a magnetically controlled growing rod for early-onset scoliosis and avoidance of the law of diminishing returns.
To assess the effect of frequent small distractions with a magnetically controlled growing rod (MCGR) on spinal length gain and achieved distraction length in children with early-onset scoliosis (EOS), and to determine whether the law of diminishing returns applies to this group of patients with MCGR. ⋯ Frequent small distractions with the MCGR for EOS enable T1-S1 and achieved distraction length gain without significant reduction in gain after repeated lengthening.
