What Is Patellar Tendonitis?
Patellar tendonitis, also known as jumper’s knee, is an overuse injury affecting the patellar tendon that connects the kneecap (patella) to the shinbone (tibia). The condition develops when repetitive stress causes irritation, inflammation, or small tears within the tendon.
Patellar tendonitis commonly affects athletes who participate in sports involving frequent jumping, running, or sudden directional changes. The condition may also develop gradually from repetitive strain and overuse during physical activity.
At Delaware Orthopaedic Specialists, our fellowship-trained knee and sports medicine specialists provide comprehensive diagnosis and treatment options designed to relieve pain, improve strength, and help patients return safely to activity.
Symptoms of Patellar Tendonitis
- Pain just below the kneecap
- Tenderness along the patellar tendon
- Pain during jumping, running, or squatting
- Stiffness in the knee joint
- Swelling or inflammation near the tendon
- Weakness during activity
- Pain that worsens with repetitive movement
Causes & Risk Factors
Patellar tendonitis develops from repetitive stress placed on the patellar tendon.
- Frequent jumping or landing activities
- Sports such as basketball, volleyball, and track
- Sudden increases in training intensity
- Muscle tightness or imbalance
- Poor conditioning or biomechanics
- Overtraining without adequate recovery
- Previous knee injuries
Diagnosis
At Delaware Orthopaedic Specialists, diagnosis begins with a detailed evaluation of the knee and patellar tendon.
- Physical examination of the knee
- Assessment of tenderness, strength, and mobility
- Review of symptoms and activity level
- Evaluation of movement mechanics and flexibility
- X-rays or MRI imaging when needed
Accurate diagnosis helps determine the severity of tendon damage and guides the most effective treatment plan.
Treatment Options for Patellar Tendonitis
Non-Surgical Treatment
Most cases of patellar tendonitis improve with conservative treatment. Non-surgical treatment options may include:
- Rest and activity modification
- Ice therapy and anti-inflammatory medications
- Physical therapy and strengthening exercises
- Stretching and flexibility programs
- Patellar tendon bracing or support straps
- Biomechanical and movement correction
- Gradual return-to-sport programs
Surgical Treatment
Surgery is less commonly required but may be recommended for severe or chronic tendon damage that does not improve with conservative treatment. Surgical options focus on repairing damaged tendon tissue and restoring knee function.
Recovery & Rehabilitation
Recovery timelines vary depending on symptom severity and the treatment approach used.
- Mild cases may improve within several weeks with rehabilitation
- Physical therapy is important for restoring strength and flexibility
- Gradual return to sports helps reduce reinjury risk
- Chronic tendon injuries may require longer recovery periods
Early treatment and proper rehabilitation can help prevent ongoing tendon damage and chronic knee pain.
