Capsular Healing in Interportal and Periportal Capsulotomy Methods of Hip Arthroscopy.

Objective: To evaluate the midterm outcomes and the capsular healing in patients who had interportal capsulotomy versus periportal capsulotomy of hip arthroscopy.

Methods: Retrospectively reviewed 33 patients with labral tear received hip arthroscopy, with an average age of 41 (27-67) years, including 13 cases of Cam deformity and three cases of Pincer deformity. All patients had positive sign of flexion adduction internal rotation or flexion abduction external rotation.

Effect of low-dose X-ray irradiation and Ti particles on the osseointegration of prosthetic.

Low-dose irradiation (LDI) exhibits a positive effect on osteoblasts and inhibitory effect of inflammation. Here, we test the hypothesis that LDI can promote osseointegration and inhibit the inflammatory membrane formation in the presence of titanium (Ti) particles. Endotoxin-free titanium particles were injected into rabbit, prior to the insertion of a Ti6-Al-4-V sticks pre-coated with hydroxyapatite.
