Outcome Measures

Primary Outcomes (1)

  • Short-term clinical outcomes of patellofemoral arthroplasty

    The clinical outcomes will be determined by comparing the preoperative questionnaire data collected with the 2 and 3-year follow-up data.

    3 years

Secondary Outcomes (2)

  • Comparison clinical outcomes of patellofemoral arthroplasty with historical controls

    3 years

  • Comparison of complications, reoperation, and failures rates of patellofemoral arthroplasty with historical controls

    3 years

Study Population

The population will include 60 patients (men and women) who undergo patellofemoral arthroplasty by one surgeon.

You may qualify if:

  • Arthroscopically demonstrated localized and isolated full-thickness articular cartilage lesions (Grade 2B or 3A-B as defined by Noyes \& Stabler9) on the patellofemoral joint.
  • Lesion is symptomatic as defined by pain, swelling, locking, or catching that affects daily activities.
  • Patient provides informed consent.
  • Patient agrees to comply with postoperative rehabilitation program.

You may not qualify if:

  • Obesity (body mass index greater than 35).
  • Arthroscopically demonstrated full-thickness articular cartilage lesions (Grade 2B or 3A-B) in the other compartments of the knee.
  • Uncorrected varus or valgus malalignment
  • Uncorrected knee joint instability
  • Knee arthrofibrosis
  • Patient unwilling to comply with postoperative rehabilitation
  • Significant muscular atrophy and weakness that does not respond to rehabilitation
  • History of alcohol or drug abuse within 3 years of the operation.
  • Disabling or widespread osteoarthritis or other joint disease in any other joint.
  • Presence of a significant connective tissue disease, autoimmune disease, HIV-positive, or immune deficiency syndrome.
  • Any contraindications to surgery or other medical disorder that in the opinion of the principal investigator would interfere with the conduct of the study.
