Abstract: [Objective] To explore the clinical outcomes of total knee arthroplasty (TKA) for Charcot arthropathy of knee.[Methods] A retrospective study was conducted on 15 patients (19 knees) who received TKA from September 2007 to December 2018 for Charcot arthropathy of knee. Of them, 6 patients (8 knees) had TKA performed with semi-restrictive prosthesis (SR) , 8 patients (9 knees) were with rotating hinge knee prosthesis (RHK) , and one patient (2 knees) was with the each above prosthesis on each knee. The perioperative, follow-up and radiographic documentations were compared between the two groups of prosthetic type. [Results]All the patients had TKA performed smoothly without serious complications, and with on statistically significant differences between the two groups regarding operative time, incision length, intraoperative blood loss, postoperative drainage, time to return ambulation and hospitalization days (P>0.05) . During follow-up period lasted for 8~120 months with an average of (39.21±33.81) months, no adverse event happened in anyone of the SR group, whereas in the RHK group 1 patients got femoral neck fracture of the affected side 1 year after operation and was treated conservatively, 1 patient suffered from prosthetic subluxation 1 year later, and had the insertion and axis components changed, 1 patient had patellar tendon tear which healed after repair. The HHS score significantly increased at the latest follow up in both groups compared with those before operation (P< 0.05) . The SR group was marked higher HHS score than the RHK group at the latest follow up regardless of no a statistical significance between them (P>0.05) . In addition, the SR group got a significant ROM increases at the follow up compared with that before operation (P<0.05) , whereas the RHK group had no significant change in ROM between the two time points (P>0.05) , therefore the SR group was significantly superior to the RHK group in ROM at the latest interview (P< 0.05) . Regarding to radiographic assessment, the SR group had significantly less hip-knee-ankle angle (HKA) than the RHK group postoperatively (P<0.05) , despite of no significant differences in coronal femoral angle (CFA) , coronal tibial angle (CTA) and posterior tibial slope (PTS) between them (P>0.05). [Conclusion] Both semi-restrictive and RHK prosthesis can be used in TKA for Charcot arthropathy of knee, and achieve good short and medium-term clinical consequences.
