BACKGROUND: Intraoperative fracture during primary Total Knee Arthroplasty (TKA) is very rare and there is little literature available which has defined the possible reasons for the occurrence of these fractures. Further, no study till date has defined the various management options available to treat these fractures. This study aims to define (1) the possible reasons for different fracture patterns occurring intraoperatively, (2) the ideal management options for each type of fracture geometry, (3) whether this intraoperative complication affects the physiotherapy protocol and long term outcomes.
METHODS: Out of 3168 primary TKA done between 2010 and 2017, 19 patients developed intraoperative fracture, whose data was evaluated retrospectively. Patients were assessed radiologically to determine the time to union and clinical outcomes were assessed using Knee Society Score.
RESULTS: Out of the 19 intraoperative fractures, 19 were in Tibia and 4 in Femur. Majority of fractures occurred during cementing and final implantation (8 cases), followed by exposure and bone preparation (6 cases) and the least during trialing (4 cases). Out of 15 Tibia fracture, 9 fractures involved the Tibial cortex which were managed with screws (4 cases), sutures and bone cement (5 cases). Stemmed tibial component was used for all Plateau type fracture patterns (6 cases). Out of 4 distal femur fractures, condylar type fracture pattern were fixed with plates and screws (3 cases) and epicondyle avulsion with screws alone (1 case). All the cases showed union (average union time 8.9 weeks) and good KSS scores which remained till their last follow-up. None of the patient developed any other complications or required revision surgery.
CONCLUSIONS: Intraoperative fracture during TKA, although rare but a significant complication which can affect the outcome, if not managed properly. We have shown methods of management for such cases, which have given excellent results.
