膝关节韧带手术比其他普通外科手术产生更多的边缘结果和并发症。前交叉韧带重建术的远期成功率为75%~90%。膝关节手术的目标是恢复膝关节的正常运动学。如果张力过高，关节的活动范围会受到限制，导致关节软骨和半月板受到异常应力，并干扰移植物的血运重建。介绍了用拉曼光谱测量韧带和肌腱张力的方法。拉曼光谱的测量表明，拉曼频率随着外加张力的增加而移动。
More marginal results and complications occur as a result of knee ligament surgery than of other common surgical procedure. Long-term success rates of anterior cruciate ligament reconstruction range between 75 and 90%. The goal of knee surgery is to restore the normal kinematics of the knee. If the tension is too high, the range of motion of the joint is restricted, resulting in abnormal stresses on the articular cartilage and the meniscuses, and interfering with the revascularization of the graft. The use of Raman spectroscopy for the measurement of tension in ligaments and tendons is described. Measurements of the Raman spectrum demonstrate that the Raman frequencies shift with applied tension.
