Distal femoral resection in total knee arthroplasty (TKA) is commonly performed using intramedullary jigs with a pre-operatively planned valgus cut angle (VCA). For valgus knees with lateral femoral condyle hypoplasia, the method of determining the accurate VCA has not been clarified. The aim of the present study is to introduce a method that can accurately determine the distal femoral VCA in the valgus knee arthroplasty. ⋯ Level IV.

The influence of chondromalacia patellae (CMP) on post-operative anterior knee pain (AKP) following total knee arthroplasty (TKA) remains controversial, and few studies have focused on the relationship between them. The purpose of this study was to determine whether different CMP grades affect the incidence of AKP after TKA without patellar resurfacing. ⋯ The findings may suggest no relevant influence of CMP grading on the incidence of AKP after TKA without patellar resurfacing.

We report the oncological and functional results of limb salvage for bone sarcomas involving the distal tibia using hybrid surgical technique of resection arthrodesis by bone transport then plating. ⋯ In carefully selected patients with primary distal tibial sarcomas, this hybrid method can effectively eliminate tumor lesion, reconstruct function, and shorten the length of wearing an external fixator by a meticulous conversion to internal fixator.

Comparative Study
A biomechanical comparison of different fixation techniques for fractures of the acetabular posterior wall.
This study aimed to evaluate the biomechanical stability of different fixation techniques for fractures of the acetabular posterior wall. The hypothesis was that a reconstruction plate, combined with compression screw fixation and a plate placed lateral to the screws, would achieve a higher peak load to failure and stiffness and reduced gapping during cycle loading than other fixation techniques. ⋯ Fixation using a reconstruction plate and compression screws placed lateral to the screws may address acetabular posterior wall fractures in a more appropriate manner than techniques using only plates or screws. However, this study does not provide evidence to support the fact that placing the plate lateral to the screws is advantageous in comparison with other techniques.

Randomized Controlled Trial
The efficacy and safety of two low-dose peri-operative dexamethasone on pain and recovery following total hip arthroplasty: a randomized controlled trial.
To evalute the efficacy and safety of two low-dose peri-operative dexamethasone on pain and recovery following total hip arthroplasty (THA). ⋯ I.
