Figure Lengend Snippet: Intraoperative fixation and follow‐up radiographs of medial femoral condylar avulsion fracture during total knee arthroplasty. (A) Intraoperative photographs showing fixation of a medial femoral condylar avulsion fracture with three cancellous screws in a 76‐year‐old male patient with right knee osteoarthritis. (B) Preoperative long‐leg radiograph indicating severe varus deformity, with hip‐knee‐ankle angle (HKA = 174°), distal femoral valgus angle (DFVA = 87°), and proximal tibial varus angle (PTVA = 83°). (C and D) Postoperative and 2‐year follow‐up radiographs demonstrating satisfactory fracture healing and stable prosthesis alignment.
Article Snippet: Treatments for femoral condylar avulsion fracture were as follows: (1) medial and lateral coronal stability was assessed, and 3.5 mm cancellous bone screws or No. 2 nonabsorbable sutures (ETHIBOND, Johnson & Johnson, USA) were fixed for patients with bone fragments greater than and less than 5 mm in thickness, separately; (2) after fixation, re‐assessed coronal stability through Bohler's test.
