In the robot-assisted reduction group, there were 13 males and 17 females, with a median age of 59.00 (53.50, 61.75) years. Patients in this group underwent closed reduction of distal radius fractures assisted by a robotic system. The system utilizes X-ray imaging to perform intelligent diagnosis of fracture types and generates an automated reduction plan. After physician review, the operator manipulates the joystick on the control console to guide the robotic arm, achieving visualization, precision, and standardization during fracture reduction. Following reduction, the limb was immobilized using small splints. In the manual reduction group, there were 12 males and 18 females, with a median age of 59.00 (55.00, 63.75) years. Patients underwent reduction using the &lt;i&gt;Wumen&lt;/i&gt; Medical School technique for distal radius fractures. The procedure involved massaging the palmar and dorsal muscle groups of the wrist to mobilize displaced fracture fragments, followed by counter-traction to correct shortening displacement. Subsequently, lifting and pressing maneuvers, along with compression, were applied to correct dorsal-palmar and lateral displacement. After reduction, small splints were used for immobilization.

KOA rabbit animal model was established by fixing and immobilizing left hind limb of rabbits in an extended position with a plaster cast for 6 weeks, following the modified Videman method. The control group was not immobilized. Both of control group and model group were not intervened. The needle knife group received needle knife intervention once a week for 4 weeks. One week later, Kellgren-Lawrence(K-L) grading and Magnetic Resonance Knee Osteoarthritis Score (MOAKS) were used to evaluate bone spurs, joint space, cartilage smoothness and effusion on the left knee joint of rabbits; Lequesne MG score was used to evaluate effects of acupuncture knife on symptoms, signs and functional activities of rabbit's knee joint. After killing rabbits, cartilage morphology of left knee joint was observed;pathological changes of cartilage on the left knee joint of rabbits were examined by hematoxylin O-eosin staining under a light microscope;TdT-mediated dUTP nick end labeling (TUNEL) staining technique was used to detect apoptosis rate of chondrocytes on the left knee joint of rabbits. Real-time quantitative polymerase chain reaction (RT-PCR) and Western blot were used to detect autophagy of chondrocytes on the left knee joint and expressions of regulatory molecules for cartilage matrix degradation, including myosin-like bcl2 interacting protein (Beclin-1), light chain 3 (LC3), miR-107, cysteine aspartate-specific protease 1 (Caspase-1), interleukin-1β (IL-1β), collagen typeⅡ(CollagenⅡ), matrix metalloproteinase-3 (MMP-3), and matrix metalloproteinase-13 (MMP-13), at mRNA and protein levels.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Compared with blank group, the surface of left knee joint cartilage in model group showed defects, with unclear structure, reduced matrix staining, disordered cell arrangement, mostly in clustered distribution, significantly reduced in quantity, and chaotic and unclear marginal lines;the apoptosis rate of chondrocytes increased, while K-L grading level, MOAKS score, Lequesne MG score rose, and visual assessment score also increased. The expressions of Caspase-1, IL-1β, MMP-3, and MMP-13 mRNA and proteins in cartilage tissue were upregulated, and all the differences were statistically significant (&lt;i&gt;P&lt;/i&gt;&lt;0.01). The expressions of Beclin-1, LC3, miR-107, CollagenⅡmRNA, as well as Beclin-1, LC3Ⅱ/Ⅰ, and CollagenⅡproteins in cartilage tissue were all decreased, and the differences were statistically significant (&lt;i&gt;P&lt;/i&gt;&lt;0.01).

In control group (Sherman type Ⅲ/ Ⅳ), there were 32 patients, including 20 males and 12 females;aged from 17 to 58 years old with an average of (34.88±11.40) years old;treated with single-bundle hamstring tendon reconstruction using residual tibial portion of ACL, and the retained residual part formed a sleeve-like covering for the reconstructed ligament.
