Patellar Tendinitis Surgery

Overview of Patellar Tendinitis

  • Patellar tendinopathy causes activity-related anterior knee pain and affects both athletes and non-athletes, commonly resulting from repetitive loading of the patellar tendon, particularly in jumping athletes 2
  • Pain is typically located at the inferior pole of the patella and is exacerbated by activities such as navigating stairs and prolonged sitting 2
  • Physical examination reveals pain at the inferior pole of the patella with the leg fully extended during resisted leg extension 2
  • A decline squat test places increased load on the patellar tendon and often reproduces the patient's pain 2

Surgical Indications

  • Patellar tendinitis surgery is an effective treatment option that should be reserved for patients who have failed conservative therapy for 3-6 months 1
  • Surgery becomes an option when conservative treatment has failed after 3-6 months 1
  • Patient continues to experience significant pain affecting quality of life 1
  • Patient is unable to return to desired activity level despite appropriate non-surgical management 1

Non-Surgical Management Before Considering Surgery

  • Relative rest and reduced activity to prevent further damage 1
  • Eccentric strengthening exercises to reduce symptoms and promote tendon healing 2
  • Deep transverse friction massage for pain reduction 2
  • Cryotherapy for acute pain relief 1
  • Short-term use of NSAIDs for pain management (though they don't affect long-term outcomes) 1

Surgical Techniques

  • Excision of abnormal tendon tissue 3
  • Performance of longitudinal tenotomies to release areas of scarring and fibrosis 3
