Application of minimally invasive arthroscopy in knee joint injuries caused by longitudinal impact of military training / 重庆医学

ABSTRACT

Objective To explore the applicationof minimally invasive arthroscopy in the knee joint injuries caused by longitudinal impact of military training.Methods A total of 538 consecutive soldier outpatients diagnosed as knee joint injuries caused by longitudinal impact of daily military training in our hospital from January 2006 to January 2015 were retrospectively analyzed.According to the Principles about Diagnosis and Treatment of Military Training Injury,the general condition,injuries types and injury subject were performed the statistical analysis.The grading diagnosis and treatment strategy of impact injuries was proposed at first time according to the MRI examination results,injury type and severity.The patients needing operative therapy were screened out for conducting the arthroscopic operation according to this strategy.All the patients receiving surgeries were evaluated by the Lysholm scoring before and after operation.The subjective evaluation satisfaction investigation was performed.Results Seventy six cases received the arthroscopic surgeries,and all the cases were followed up successfully.The duration of following-up ranged 12-35 months.The Lysholm scores before operation was[46.3 ± 5.3]which were lower than [83.7±3.8] after operation,the difference was statistically significant(P＜0.01).The wounds healed at the first stage,and no complications of nerve and blood vessel injury,infections,etc.occurred.The patients subjectively felt that the knee joint function was significantly improved,71 cases satisfied with the arthroscopic operation effect,the satisfactory rate was 93.4％.All the cases went back to the normal training life after surgeries.Conclusion For the knee joint injuries caused by longitudinal impact of military training,the prevention is the key role.On the basis of preliminary diagnosis by the physical examination and imaging examination,the treatment should be combined with the grading diagnosis.and treatment strategy.In the operation therapy,the minimally invasive arthroscopy as an examination and treatment means can more comprehensively evaluate the knee injury condition,timely repair injured meniscus and conduct the ligament reconstruction,which has small trauma and recovers rapidly,the patient can recover the routinemilitary training as soon as possible.The arthroscopy is the first choice of treatment scheme for the patients with grade Ⅲ or more injury.
