Salvaging a failed proximal interphalangeal (PIP) joint implant arthroplasty remains a considerable technical and rehabilitation challenge. Experienced arthroplasty surgeons have reported 70% survival of revision PIP implants at 10 years with 25% of patients requiring subsequent revision surgery. At this time, there is no consensus surgical approach or implant proven superior for revision implant arthroplasty of the PIP joint. Secondary arthrodesis or amputation may be required to salvage the failed PIP implant arthroplasty with compromised bone stock or soft tissue envelopes that are inadequate for implant arthroplasty.
挽救失败的近端指间（PIP）关节置换术仍然是一项颇具技术难度和康复挑战的工作。经验丰富的关节置换外科医生报告称，翻修PIP植入物在10年时的生存率为70%，25%的患者需要后续翻修手术。目前，对于PIP关节翻修植入物置换术，尚无经证实的、被普遍认可的手术方法或植入物。对于骨量不足或软组织包膜不足以进行植入物置换术而导致PIP植入物置换术失败的情况，可能需要进行二期关节融合术或截肢来挽救。
