ABSTRACT

OBJECTIVE: To investigate the expression and clinical significance of serum soluble AXL in patients with radiographic knee osteoarthritis (KOA). METHODS: There were 183 patients with KOA who were selected and divided based on the Kellgren-Lawrence (KL) score into KL 0 subgroups (n = 42), KL I-II subgroups (n = 90), and KL III-IV subgroups (n = 51). Healthy volunteers (n = 170) in our hospital were selected with matched age and gender as the control group. AXL level in serum was detected by enzyme-linked immunosorbent assay. The correlation between serum AXL with severity and clinical indicators of osteoarthritis was analyzed. RESULTS: The level of serum AXL was significantly higher in the osteoarthritis group than that in the control group (P < .05). In the osteoarthritis patients, serum AXL level was increased with the increase of KL score. Serum AXL level was positively correlated with age, body mass index, erythrocyte sedimentation rate, serum C-reactive protein, cartilage oligomeric protein, matrix metalloproteinase-13, and transforming growth factor-ß1 levels. The cut-off value for serum AXL was determined as 33.375 ng/mL by receiver operating curve analysis. CONCLUSION: The level of serum AXL in patients with osteoarthritis is significantly higher than in healthy controls, and is closely related to the severity of radiographic osteoarthritis.

ABSTRACT

BACKGROUND: Currently, total hip arthroplasty is a recognized and preferred method for treatment of adult congenital acetabular dysplasia, however, there were lack of ideal evaluation methods to precisely solve acetabular reconstruction in the process of treatment. OBJECTIVE: To investigate the evaluating effects and biological properties of computer aided technology in adult acetabular dysplasia after total hip arthroplasty.METHODS: The clinical data from 80 patients with adult congenital acetabular dysplasia who received the treatment at Department of Bone and Joint Surgery, Changhai Hospital, Second Military Medical University of Chinese PLA from January 2015 to August 2015 were selected and analyzed. Al the enrol ed patients underwent total hip arthroplasty. Al the patients were randomly divided into control and computer-aided technology groups. CT scanning was conducted in these two groups before replacement. Three-dimensional reconstruction measuring and surgical rehearsal on the acetabular site were conducted using M3D visualization software in the computer-aided technology group. The effects and biological properties of total hip arthroplasty were compared between these two groups. RESULTS AND CONCLUSION: Patients in these two groups primarily healed after replacement. The excel ent and good rate, Harris score after treatment, acetabular component, valgus angle and anteversion in the computer-aided technology group were significantly higher than those in the control group (P < 0.05). The acetabular cup abduction angle offset degrees, acetabular cup anteversion offset degrees, and the incidences of complications after replacement were significantly decreased compared with those in the control group (P < 0.05). These results suggest that the effect of computer-aided evaluation in adult acetabular dysplasia after total hip arthroplasty is ideal, and can accurately grasp the true acetabular anatomical characteristics and the corresponding relationship with the prosthesis, so as to help patients to choose the proper acetabulum and acetabular prosthesis and reconstruction ways and improve the biological performance of acetabulum after replacement, with a high clinical value.
