Objective To analyze the cartilage repair effect of Ruanshang Lotion on patients with knee osteoarthritis (KOA). Methods A total of 152 KOA patients admitted to our hospital from May 2020 to March 2025 were randomly divided into two groups (76 cases each) using a random number table. The control group received conventional KOA treatment, while the observation group received Ruanshang Lotion in addition to the conventional treatment. The clinical efficacy, TCM syndrome scores, levels of inflammatory factors, knee joint recovery, deep cartilage repair, and cartilage tissue indicators were compared between the two groups. Results After treatment, 74 cases were included in the observation group and 72 in the control group. The total effective rate in the observation group (89.19%) was higher than that in the control group (76.39%) (P<0.05). The TCM syndrome scores in both groups decreased compared with those before treatment, and were lower in the observation group than in the control group (P<0.05). After 4 weeks of treatment and at the end of treatment, the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in both groups decreased compared with those before treatment (P<0.05), and were lower in the observation group than in the control group (P<0.05). After 4 weeks of treatment and at the end of treatment, the index of severity for osteoarthritis (ISOA), visual analog scale (VAS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in both groups decreased compared with those before treatment, and were lower in the observation group than in the control group (P<0.05). Before treatment, there were no statistically significant differences between the two groups in the levels of C-telopeptide of type Ⅱ collagen (CTX-Ⅱ), cartilage oligomeric matrix protein (COMP), matrix metalloproteinase-13 (MMP-13), or a disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS4) (P>0.05). After 4 weeks of treatment and after 8 weeks of treatment, the levels of CTX-Ⅱ, COMP, MMP-13, and ADAMTS4 in both groups decreased compared with those before treatment; however, there were no statistically significant differences between the two groups in CTX-Ⅱ, COMP, or MMP-13 (P>0.05), while ADAMTS4 in the observation group was lower than that in the control group (P<0.05). After 8 weeks of treatment, the levels of CTX-Ⅱ, COMP, MMP-13, and ADAMTS4 in the observation group were lower than those in the control group (P<0.05). During the treatment period, there was no statistically significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion The application of Ruanshang Lotion in the treatment of patients with knee osteoarthritis can reduce the body's inflammatory response, alleviate cartilage damage, relieve clinical symptoms, improve clinical efficacy, and does not increase the incidence of adverse reactions.
