Summary

A case of patellar subluxation after medial plica excision is presented. Thorough preoperative evaluation is crucial for patients with symptomatic plica to prevent such complications.

Area of Science:

  • Orthopedic surgery
  • Biomechanics
  • Knee joint anatomy

Background:

  • Medial plica syndrome can cause knee pain and mechanical symptoms.
  • Surgical excision is a treatment option for symptomatic plica.
  • The biomechanical role of the medial plica in patellar stability is not fully understood.

Observation:

  • A case of patellar subluxation occurred postoperatively after medial plica excision.
  • The patient presented with instability and abnormal patellar tracking.
  • This complication highlights a potential iatrogenic effect of plica surgery.

Findings:

  • The medial plica exerts a biomechanical influence on patellar tracking.
  • Incomplete preoperative assessment may overlook factors predisposing to patellar instability.
  • Excision of the medial plica can alter the knee's biomechanical environment.

Implications:

  • Emphasizes the importance of comprehensive preoperative evaluation for symptomatic plica.
  • Suggests considering patellar stability during preoperative assessment.
  • Highlights potential risks associated with medial plica excision and the need for careful surgical technique.
