“…Niki reported that the arthroscopic radiofrequency cleaning of the joint capsule and the radial wrist short extensor joint can resume work in an average of 2.2 weeks after the operation, and the grip strength can reach 96% of the contralateral side [ 10 ]. Kambara proposed that arthroscopic surgery can directly observe the diseased tissues of the joints and loosen them under direct vision, making the operation more intuitive and accurate, avoiding the blindness of percutaneous release, and cleaning the degenerated tissues on the joint surface at the same time [ 11 ]. The above studies are mostly in the detection stage, and they are blind in treatment, and the cost is high and the recurrence rate is high.…”

The incidence of inverted knee osteoarthritis is slowly increasing, there are technical limitations in the treatment, and the operation is difficult. In this article, we will study the benefits and costs of arthroscopic cleaning treatments based on intelligent electronic medicine. This article focuses on knee osteoarthritis patients in the EL database. There are 12 male patients, accounting for 66.67%, and 6 female patients, accounting for 33.33%. The average body mass index (BMI) of the patients was 28.08, the average time from first knee discomfort to surgery was 28.44 months, and the average time of arthroscopic debridement treatment for patients with VKOH knee osteoarthritis was 143.11 minutes. One case of perioperative complication occurred within 35 days after operation, which was a soleus muscle intermuscular venous thrombosis. After immobilization and enhanced anticoagulation for 1 week, it was stable without risk of shedding. The average postoperative study time was 20.00 months. The electronic medical arthroscopy cleaning treatment plan in this article can greatly improve the quality of life of patients and can check the pathological state in time, with low cost. In the course of treatment, comprehensive treatment costs can be saved by 45%. Arthroscopic clean-up treatment can not only reduce knee pain and other uncomfortable symptoms, restore normal knee joint function, and improve the quality of life of patients, but also correct the unequal length of the lower limbs, thereby avoiding spinal degeneration caused by knee instability. Therefore, it is the first choice for the treatment of advanced knee osteoarthritis in patients with VKOH.

“…2 This may be particularly important in ACLR via the outside-in technique, as the intra-articular aperture is more acute in the outside-in technique compared with the transportal technique. 3 A common complication after ACLR with hamstring autografts is bone tunnel enlargement. [4][5][6] The presence of large tunnels often severely complicates revision ACLR surgery and may necessitate staged reconstruction and additional operative procedures that are associated with marked costs.…”

Purpose: The correlation between the graft bending angle (GBA) of the anteromedial bundle and posterolateral bundle after anterior cruciate ligament reconstruction (ACLR) and postoperative tunnel enlargement was evaluated. Methods: Two hundred fifty-eight patients (137 males, 121 females; mean age 27.3 years) who had undergone doublebundle ACLR were included. Computed tomographic scans of the operated knee were obtained at 2 weeks and 6 months postoperatively. The area of the tunnel aperture for femoral anteromedial tunnel (FAMT) and femoral posterolateral tunnel (FPLT) was measured; the area at 2 weeks after ACLR was subtracted from the area at 6 months after ACLR and then divided by the area at 2 weeks after ACLR. The femoral tunnel angles were obtained with Cobb angle measurements. The femoral tunnel angle in the coronal plane was measured relative to the tibial plateau (coronal GBA). On the median value, the patients were divided into two groups in each of FAMT and FPLT; those with a coronal GBA of FAMT of !27 were classified as group A, while those with a coronal GBA of <27 were classified as group B, those with a coronal GBA of FPLT of !23 were classified as group C, while those with a coronal GBA of<23 were classified as group D. Results: Group A included 129 knees, while group B included 129 knees. Groups A and B did not significantly differ regarding FAMT enlargement. Group C included 133 knees, while group D included 125 knees. The percentage of FPLT enlargement in group C was significantly smaller than that in group D (p ¼ 0.001). Conclusions: A steep coronal GBA of the FPLT after ACLR results in greater FPLT enlargement. The present findings suggest that surgeons should avoid creating a steep GBA of the FPLT in the outside-in technique.
