Abstract:

BACKGROUND: Total knee arthroplasty is one of the most effective and successful operations for the treatment of various end-stage or severe knee diseases. However, there is no consensus about routine patella resurfacing in total knee arthroplasty.

 
OBJECTIVE: To investigate the efficacy of patellar arthroplasty in one-stage bilateral total knee arthroplasty for the treatment of knee osteoarthritis.
METHODS: Patients undergoing bilateral total knee arthroplasty were selected from the Department of Orthopedic Surgery, Affiliated Hospital of Qingdao University in China between February 2013 and February 2014. They were randomly assigned to two groups. Patellar resurfacing group received patellar arthroplasty. Non-patellar resurfacing group did not receive patellar arthroplasty.
RESULTS AND CONCLUSION: At 3, 6 and 12 months following the surgery, no significant difference in Knee Society Score and range of motion of knee joint was detected between the two groups (P > 0.05). 12 cases experienced anterior knee pain, including 4(13%) of the patellar resurfacing group and 8(27%) of the non-patellar resurfacing group. There were no complications such as prosthesis fracture, loosening, displacement, patellar fracture or patellar necrosis, and patellar prosthesis revision. Results verified that patellar arthroplasty and non-patellar arthroplasty have the same short-term effectiveness in one-stage bilateral total knee arthroplasty for osteoarthritis.
