OBJECTIVE: To observe the efficacy of distal tibial tuberosity high tibial osteotomy in treating medial compartment osteoarthritis of the knee. In the experiment, a medical image enhancement algorithm based on shear wave domain improved Gamma correction was implemented to process medical images in order to diagnose patients more effectively.
METHODS: Sixty-five patients (13 males and 52 females) were included in the study who were treated with distal tibial tuberosity high tibial osteotomy, and the mean age of the patients was 63±6 years (range 49-73). All patients received X-Ray and MRI before surgery. We carefully studied and analyzed the findings, MRI findings and medical characteristics after using the shearlet domain to improve the Gamma correction method in order to enhance diagnostic accuracy. The improved image help us to judge the damage of the medial and lateral compartment more accurately. Weight bearing line (WBL) and femora-tibial Angle (FTA) were measured to evaluate the lower limb alignment before and 12 months after surgery. Visual analogue scale (VAS) scores, Hospital for Special Surgery (HSS) scores, the Westrn Ontario and Mcmaster Universities (WOMAC) scores were recorded to evaluate knee pain and function before surgery, 3 months and 6 months after surgery.
RESULTS: The X-Ray and MRI scans of the patients were analyzed. After the shear wave shearlet domain is implemented, the image effect is significantly improved. 12 months after surgery, WBL was improved from 16.34±2.18% to 60.32±2.89% (p<0.05), FTA was improved from 171.17±1.87° to 179.83±2.14° (p<0.05). At 3 months and 12 months after surgery, VAS, HSS and WOMAC scores were significantly improved compared with baseline (p<0.05).
CONCLUSION: Distal tibial tuberosity high tibial osteotomy is able to correct varus deformity, relieve knee pain and the functional dysfunction, indicating which had a significant short-term efficacy. The shear wave shearlet domain incorporates the Gamma correction method to effectively preserve the image details, which to achieve a more accurate diagnosis, and help us to judge the damage of the medial and lateral compartment more accurately.
