Patellectomy for chondromalacia yielded mixed results, with many patients reporting satisfaction despite poor to fair knee ratings. Long-term outcomes show limited excellent results but significant patient contentment.

Area of Science:

  • Orthopedic Surgery
  • Knee Biomechanics
  • Cartilage Degeneration

Background:

  • Chondromalacia patellae is a common cause of anterior knee pain.
  • Patellectomy is a surgical option for severe chondromalacia.
  • Long-term outcomes of patellectomy require further investigation.

Purpose of the Study:

  • To evaluate the long-term functional outcomes and patient satisfaction after patellectomy for chondromalacia.
  • To assess the correlation between objective knee ratings and subjective patient satisfaction.

Main Methods:

  • A retrospective review of 15 patients who underwent 17 patellectomies for chondromalacia.
  • Average follow-up of 5.5 years.
  • Objective knee function was assessed using a rating scale (excellent, good, fair, poor).

Main Results:

  • No knees were rated as excellent; 5 were good, 9 fair, and 3 poor.
  • Despite functional limitations, 10 out of 15 patients reported satisfaction with the surgical outcome.
  • Bilateral patellectomies were included in the patient cohort.

Conclusions:

  • Patellectomy for chondromalacia can lead to patient satisfaction even with suboptimal objective knee function.
  • The decision for patellectomy should consider patient-reported outcomes alongside functional assessments.
  • Further research is needed to optimize surgical techniques and patient selection for patellectomy.
