肩袖撕裂是常见的引起肩关节疼痛、活动受限和功能障碍的原因，肩袖撕裂导致一系列的肩关节炎症并影响日常生活质量，如肩关节疼痛，并由肩关节疼痛引起的夜间不能睡觉、不能梳头以及女性患者不能脱胸罩等。针对其治疗方案有一系列的手术方法比如肌肉肌腱移植、上关节囊重建或者反肩置换手术等，但是，肌肉肌腱移植会破坏正常的结构，破坏解剖；反肩置换价格昂贵，且技术难度大不易普及；而上关节囊重建科学证据有待加强。
现有的市场上存在一种生物可降解的肩锋垫，将其植入肱骨和肩锋之间，允许其无摩擦的滑行以恢复肩关节生物力学，但是，该肩锋垫内填充液体，长时间使用时由于重力影响会下滑至人体其他部位，引发人体其他不适。且该肩锋垫受力时容易发生变形，变形的肩锋垫会挤压肩部其他组织，导致患者疼痛加重。进一步地，该肩锋垫采用可生物降解的材料制成，导致该肩锋垫长期使用后会在肩关节内掉落异物，引发其他炎症。
