ABSTRACT
Objective To investigate the clinical efficacy of a needle knife in treating knee meniscus injury. Methods One hundred patients with knee meniscus injury (112 knee joints) were randomly allocated to treatment and control groups, 50 cases each. The treatment group received needle knife therapy and the control group, an injection of sodium hyaluronate injectio into knee joint cavity. The main clinical symptoms and signs around the knee joint were observed and the knee function score was recorded in the two groups before and after treatment. the clinical therapeutic effects were evaluated in the two groups. Results There were statistically significant differences in pre-/post-treatment main clinical symptom and sign index (pain score, swelling score, activity score and tenderness index score) difference values between the two groups (P<0.05). There were statistically significant differences in the main clinical symptom and sign index difference values at follow-up compared with before treatment between the two groups (P<0.05). There was a statistically significant differences in the knee function score after treatment and at follow-up compared with before treatment in the two groups (P<0.01,P<0.05). There was a statistically significant differences in the knee function score between the treatment and control groups after treatment and at follow-up (P<0.05). Post-treatment excellence rate and total efficacy rate were 94.0%and 100.0%, respectively, in the treatment group and 72.0%and 98.0%, respectively, in the control group. There was a statistically significant differences in post-treatment excellence rate between the two groups (P<0.05). Follow-up excellence rate and total efficacy rate were 96.0% and 100.0%, respectively, in the treatment group and 76.0% and 98.0%, respectively, in the control group. There was a statistically significant differences in follow-up excellence rate between the two groups (P<0.05). Conclusion Needle knife therapy is an effective way to treat knee meniscus injury.
ABSTRACT
ObjectiveTo observe andanalyze the clinical efficacy of needle knife treatment for knee meniscus injury from improving knee biomechanical balance and to provide a therapeutic basis and method for clinical practice.MethodOne hundred patients (112 knees) with knee meniscus injury meeting the inclusion criteria were allocated, in order of visits, to observation and control groups, 50 cases each. They were treated with a needle knife and an injection of sodium hyaluronate injectio into knee joint cavity, respectively. Changes in the indices were observed and assessed in the two groups by recording the plantar pressure analysis score and the knee function score before and after treatment and at follow-up. The clinical therapeutic effects were evaluated in the two groups.ResultThemaximum load, time integral difference value and load ratio around the knee joint decreased significantly in both observation and control groups after treatment and at follow-up (P<0.05). The regulating effect on knee joint force balance was better in theneedle knife group than in the control group (P<0.05). The improving effect on knee joint function was significantly better in the observation group than in the control group (P<0.01). The excellence rate was significantly higher in the observation groupthan in the control group after treatment and at follow-up (P<0.05).ConclusionNeedle knife treatment restores the function of the knee joint by loosing focal soft tissues around the knee joint, improving knee joint load imbalance and correcting the mechanical equilibrium around the knee joint in patient with knee meniscus injury. It has a definite curative effect on the disease.
