Objective:
To summarize the principle, classification, and treatment methods of knee extension device disruption after total knee arthroplasty (TKA).
Methods:
By extensively consulted the relevant domestic and abroad literature, the principle, classification, and treatment methods of injury according to different parts of the knee extension device after TKA were summarized and analyzed.
Results:
The knee extension device disruption after TKA mainly occurs in the quadriceps tendon, patella tendon, and patella. Once the knee extension device is injured, it will seriously affect the functional recovery of the patient after surgery, resulting in delayed knee extension, limited range of motion, difficulty walking, and joint pain, etc. The current treatment methods are diverse, including conservative treatment and surgical treatment. Surgical treatment includes direct suture repair (traditional perosseous fixation and suture anchoring techniques), reconstruction and reinforcement repair (reconstruction using synthetic patches, autografts, and allografts). For the treatment of different parts, it is necessary to comprehensively consider the patient's knee joint tissue condition, the presence or absence of underlying diseases, and the presence or absence of donors.
Conclusion:
There is no uniform conclusion on the treatment of knee extension device disruption after TKA. Different injury situations need to be considered comprehensively to choose the appropriate treatment method.
