To explore the clinical outcomes of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF). ⋯ Both the methods can obviously relieve pain and completely or partly recover daily life function in treating OVCF. But PKP has advantages of recovery of anterior height of responsibility vertebra and correction of Cobb angle, especially for serious compression.

To solve the problem of screw penetrating the joint surface easily by determining the angle of inclination and the mean longth screw plated on the posterior column. ⋯ When using the fixation technique of acetabular posterior column plate, the angles of screw-posterior column are 40 degrees to 60 degrees, 60 degrees to 75 degrees, 75 degrees to 90 degrees and 90 degrees to the angle of parallel to the square area respectively on the region of outer 1/4,outer-middle 1/4,inner-middle 1/4 and inner 1/4 of the acetabulum region, and the screw length is 30 mm.

Total knee arthroplasty (TKA) identified as an effective treatment for ultimate knee joint disease can effectively relieve pain, correct deformity, improve knee function and enhance the quality of life of patients. Patient satisfaction has been increasingly considered as an important factor in evaluating the success of primary TKA. Anterior knee pain that usually appears in the region of the anterior knee is a recognized complaint for primary TKA and has a strong impact on the improvement of knee function and patient satisfaction of primary TKA. ⋯ However, none of the past treatment such as patellar resurfacing, patellar denervation without patellar resurfacing or a mobile-bearing prosthesis has a good and affirmative effect on it. The prevention and treatment of anterior knee pain following primary TKA still is a difficult solved problem. To address this problem, we need further researches about the cause of anterior knee pain, knee joint prosthesis and biomechanics of patellofemoral joint, as well as lots of randomized controlled trials.

Randomized Controlled Trial
[Case-control study on earlier medial tibial pain after total knee arthroplasty].
To compare the difference of anterior knee pain after total knee arthroplasty (TKA) between the ways using periosteal dissector and electric scalpel to release medial collateral ligament and pes anserinus. ⋯ Compared with using electric scalpel,using periosteal dissector used to release medial collateral ligament and pes anserinus may cause more anterior knee pain after total knee arthroplasty.
