Exclusion criteria

  • Valgus deformity
  • History of inflammatory arthroplathy
  • Previous fracture or open surgery on the same knee
  • History of patellar instability

Treatment and study plan

Total knee arthroplasty

Procedure

A surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses)

Patellar Denervation

Procedure

circumpatellar electrocautery with monopolar coagulation diathermy

Primary outcomes

  1. Change of post-operative anterior knee pain

    Time frame: Change from baseline Visual Analog Scale for anterior knee pain at 3 months, 6 months, and 12 months after surgery

    Visual Analog Scale for anterior knee pain (minimum 0, maximum 10) Do higher values represent a worse outcome

Secondary outcomes

  1. range of motion of knee

    Time frame: Change from baseline range of motion of knee at 3 months, 6 months, and 12 months after surgery

    degree of motion of the knee after surgery

  2. Knee Society and Knee Society function score

    Time frame: Change from baseline Knee Society and Knee Society function score at 3 months, 6 months, and 12 months after surgery

    Knee Society and Knee Society function score (minimum 0, maximum 200)

  3. New patellar score (Bartlett score)

    Time frame: Change from baseline new patellar score at 3 months, 6 months, and 12 months after surgery

    New patellar score or Bartlett score (minimum 0, maximum 30)

  4. Oxford knee score

    Time frame: Change from baseline Oxford knee score 3 months, 6 months, and 12 months after surgery

    Oxford knee score (minimum 0, maximum 48)

  5. patellar shift index

    Time frame: Change from baseline 3 months, 6 months, and 12 months after surgery

    The estimation of patellar position relative to the trochear

  6. prevalence of anterior knee pain

    Time frame: Change from baseline prevalence of anterior knee pain at 3 months, 6 months, and 12 months after surgery

    Percent of anterior knee pain

  7. activity of daily living

    Time frame: Change from baseline activity of daily living at 3 months, 6 months, and 12 months after surgery

    activity of daily living score (minimum 0, maximum 20)

  8. post-operative complication

    Time frame: Number and type of post-operative complication at 3 months, 6 months, and 12 months after surgery

    Number and type of post-operative complication
