Correlation Analysis Between MSTS Score And Gaitogram In Patients With Tumors Around The Knee Joint After Surgery

Research background and purposeThe knee joint is the most common site for bone and soft tissue tumors.With the advancement and development of imaging technology,comprehensive treatment,and surgical techniques,limb salvage surgery has gradually become the main surgical method for treating tumors around the knee joint.After resection of tumors around the knee joint,the recovery of knee joint function is related to many factors.Reported factors included age,patient’s sex,body mass index,tumor size,tumor location,and tumor nature.Evaluation of the medial or lateral approach to the tumor resection incision,the reconstruction scheme,and the application of microwave ablation has not been studied so far.The first purpose of this study is to analyze the influencing factors of postoperative function of tumors around the knee joint,and provide a scientific basis for formulating targeted postoperative clinical intervention plans and promoting postoperative functional recovery.There are many surgical approaches for the knee joint,which can be mainly divided into medial incision,lateral incision,anterior median incision,or posterior median incision,etc.,and the appropriate approach for resection is mainly selected according to the extent of the tumor,the site of the previous biopsy,and the function of the affected limb.The second objective of this study was to investigate the difference in postoperative kinematic function recovery in patients with tumors around the knee who underwent medial and lateral approaches.Enneking et al.developed the Musculoskeletal Tumor Society scoring system for subjective assessment of functional assessment in patients with bone and soft tissue tumors of the extremities,while the gait chart is less susceptible to patient emotions and may be a useful assessment of motor function after surgery for tumors around the knee potential complementary or alternative approaches.The third aim of this study was to investigate the relationship between gait analysis results and MSTS scores,and to explore whether gait charts could be used as an objective,quantitative supplementary or alternative method.MethodsA total of 40 patients were included in this study for postoperative follow-up.1.Using MSTS score and gaitogram as the functional prognosis results,analyze the influencing factors of postoperative function.2.Divide patients into medial approach group and lateral approach group,collect postoperative gait,and analyze kinematic differences between the two groups.3.The postoperative MSTS score and gaitogram were used for correlation analysis.Result1.Taking MSTS score and gaitogram score as the functional prognosis results,through analysis and testing,there are statistical differences in postoperative complications,postoperative time and postoperative functional exercise.2.In the degree of freedom of internal/external rotation of the knee joint,the lateral approach group exhibited a small external rotation value at 38-45%of the gait cycle and internal rotation at 61-85%of the gait cycle.In terms of proximal/distal displacement degrees of freedom,the lateral approach exhibits distal displacement at 49-50%of the gait cycle.3.MSTS total score was statistically correlated with gaitogram total score,maximum knee flexion angle and gait speed;while gaitogram total score was correlated with MSTS total score,limb daily function,postoperative satisfaction,walking function and walking form There is a statistical correlation.In the subgroup analysis,the MSTS total score and each sub-item of the affected limb were significantly positively correlated with the gait speed of the affected limb;the daily function of the limb,the walking function of the limb,and the walking form of the limb in the MSTS total score and the sub-item were positively correlated with the maximum flexion and extension angle.ConclusionThis study reveals that postoperative complications,postoperative time,and postoperative functional exercise have an important impact on the postoperative functional recovery of patients with tumors around the knee joint.When it comes to surgery for patients with tumors around the knee,the functional recovery of the surgical approach in patients with tumors around the knee should be considered,and the gait chart shows that the lateral approach may be better than the road.The results of the gait chart are highly correlated with the MSTS score and are a supplement to the objective assessment of postoperative functional outcomes and the MSTS score,helping to improve rehabilitation programs for individual functions.
