Tendinitis of left quadriceps tendon

Last edited: 4/15/2026

Overview

Tendinitis of the left quadriceps tendon involves inflammation or irritation of the tendon connecting the quadriceps muscle to the patella, often causing pain and functional impairment in the anterior knee region 1.

Diagnosis

  • Clinical Presentation: Pain localized to the anterior knee, exacerbated by activities like knee extension and resisted flexion.
  • Physical Examination: Tenderness over the quadriceps tendon, particularly at the patellar insertion, and decreased range of motion.
  • Imaging: Ultrasound or MRI may be used to rule out other conditions such as tears or bursitis 1.
  • Management

  • Immobilization: Initial knee flexion to 120 degrees for 24 hours to reduce swelling and pain 1.
  • Activity Modification: Avoid activities that exacerbate symptoms; gradual return to normal activities as tolerated.
  • Physical Therapy: Includes quadriceps strengthening exercises and stretching once acute symptoms subside 1.
  • Special Populations

  • No Specific Guidance Provided: The provided abstract does not cover special populations such as pregnancy, pediatrics, elderly, or comorbidities 1.
  • Key Recommendations

  • Immediate Immobilization: Flex knee to 120 degrees for 24 hours post-injury to manage acute symptoms effectively (Evidence: Weak) 1.
  • Gradual Return to Activity: Advise a gradual reintroduction to physical activities following immobilization to prevent re-injury (Evidence: Expert opinion) 1.
  • Physical Therapy: Incorporate quadriceps strengthening and flexibility exercises post-acute phase to restore function (Evidence: Expert opinion) 1.
