Significant and lasting improvement in stiff MP and PIP joints can be achieved by operative management. Operative intervention should be considered only after persistence of stiffness after a vigorous program of nonoperative therapy. In our series of 135 such stiff finger joints, capsulotomy increased the range of motion in MP joints by more than 30 degrees in 68 percent of the patients, more than 50 degrees in 57 percent, and more than 70 degrees in 32 percent. The increased range of motion for the PIP joints was more than 30 degrees in 63 percent of the patients, more than 50 degrees in 41 percent, and more than 70 degrees in 25 percent.
通过手术治疗可显著且持久地改善掌指关节（MP）和近端指间关节（PIP）的僵硬状况。仅在积极的非手术治疗方案后僵硬仍持续存在时，才应考虑手术干预。在我们的135例此类僵硬手指关节病例系列中，关节囊切开术使68%的患者掌指关节活动范围增加超过30度，57%的患者增加超过50度，32%的患者增加超过70度。近端指间关节活动范围增加超过30度的患者占63%，增加超过50度的患者占41%，增加超过70度的患者占25%。
