Understanding Patellar Tendonitis
Before delving into patellar tendonitis treatment options, it's essential to understand what patellar tendonitis is, its causes, and how it progresses.
Definition and Causes
Patellar tendonitis, also commonly known as jumper's knee, is an overuse injury that often affects athletes involved in sports requiring frequent jumps like basketball and volleyball. It occurs due to repeated stress on the patellar tendon, leading to tiny tears that cause inflammation and weakening of the tendon. However, individuals not participating in jumping sports can also develop patellar tendinitis.
This condition is caused by inflammation or irritation of the patellar tendon tissue due to overuse, particularly through repeated jumping motions that strain the tendon, as is common in professional basketball and volleyball athletes [2]. The strain gradually wears down the patellar tendon over time.
Symptoms and Progression
Typically, the first sign of patellar tendonitis is knee pain, which can range from mild to severe depending on the extent of the damage. Over time, the condition may progress to patellar tendinopathy if the tendon damage extends beyond a few weeks [1].
At onset, the discomfort may only occur during physical activity, like playing sports. As the condition worsens, pain can persist even during everyday activities like climbing stairs or sitting for long periods. It's important to seek medical advice if you experience persistent knee pain, as early diagnosis and treatment can prevent further damage and help speed up recovery.
If left untreated, patellar tendonitis can make it difficult to perform movements that require bending the knee, such as jumping, running, or even walking. This is why understanding the causes and symptoms is crucial to managing the condition and exploring appropriate patellar tendonitis treatment options.
Treatment Approaches for Patellar Tendonitis
When it comes to managing patellar tendonitis, an array of treatment options is available. These range from conservative therapies to physical therapy techniques and injection treatments. The main objective of these patellar tendonitis treatment options is to help manage symptoms and strengthen the knee's soft tissues.
Conservative Therapies
Conservative therapies are usually the first line of treatment for patellar tendonitis. These treatments aim to reduce pain and inflammation and typically include rest, avoiding activities that exacerbate the injury, applying ice, and taking over-the-counter anti-inflammatory medications.
In the case of small or partial tears of the patellar tendon, rest and rehabilitation exercises are recommended. For more serious injuries, the use of a knee brace for 3–6 weeks might be necessary to immobilize the joint and allow the tendon to heal.
Conservative treatment options for patellar tendinopathy might also include therapeutic exercises (such as eccentric training), and extracorporeal shock wave therapy (ESWT) [4].
Physical Therapy Techniques
Physical therapy plays a vital role in the treatment of patellar tendonitis. Therapeutic exercises, particularly eccentric training, are often considered the treatment of choice for patients suffering from this condition [4].
Extracorporeal shockwave therapy (ESWT) is a promising physical therapy treatment for patients with chronic patellar tendinopathy, especially when combined with eccentric training.
Physical therapy is also recommended to restore movement gradually, with strengthening and stretching exercises to be done at home.
Injection Treatments
Injection treatments have also shown promise in the treatment of patellar tendinopathy. These treatments include platelet-rich plasma (PRP), sclerosing polidocanol, steroids, aprotinin, autologous skin-derived tendon-like cells, and bone marrow mononuclear cells.
However, it's important to note that while these injection treatments show promise, more high-quality studies are needed to determine their efficacy.
In conclusion, the treatment of patellar tendonitis typically begins with less invasive treatments such as medications and physical therapy techniques before considering more invasive options. The severity of the injury, the patient's overall health, and the patient's personal goals and lifestyle all play a role in determining the best course of treatment.
Advanced Treatment Options
When conservative therapies do not produce satisfactory results in the treatment of patellar tendonitis, advanced treatment methods may be considered. These include Platelet-Rich Plasma Therapy, Autologous Blood Injection, and surgical interventions.
Platelet-Rich Plasma Therapy
Platelet-Rich Plasma (PRP) Therapy has been recognized as an effective treatment for chronic patellar tendinopathy. PRP involves the use of injections filled with a concentration of the patient's own platelets to accelerate the healing of injured tendons. A systematic review and meta-analysis involving 70 studies and 2530 patients found that multiple PRP injections demonstrated the best results at long-term follow-up (≥6 months), outperforming eccentric exercise and extracorporeal shockwave therapy (ESWT).
Autologous Blood Injection
Autologous Blood Injection (ABI) is another advanced treatment option for patellar tendonitis. It is a similar procedure to PRP therapy, in which a patient's own blood is injected into the affected area to stimulate healing. More research is required to evaluate the effectiveness of ABI compared to other treatments, but it offers another potential avenue for patients seeking relief from chronic patellar tendinopathy.
Surgery Considerations
If non-surgical treatments have been thoroughly explored without satisfactory results, surgical intervention may be considered. Surgery is typically recommended for patients who have diligently pursued conservative treatment without success for more than 3-6 months. Surgical treatment options include longitudinal splitting of the tendon, excision of abnormal tissue (tendonectomy), resection and drilling of the inferior pole of the patella, and closure of the paratenon. Arthroscopic techniques may also be employed, such as shaving of the dorsal side of the proximal tendon, removal of the hypertrophic synovitis around the inferior patellar pole with a bipolar cautery system, and arthroscopic tendon debridement with excision of the distal pole of the patella [4].
It's crucial for patients to discuss their specific case with a medical professional to assess the potential benefits and risks associated with each of these advanced patellar tendonitis treatment options. The chosen course of treatment should align with the patient's individual needs, lifestyle, and recovery goals.
Recovery and Rehabilitation
The road to recovery from patellar tendonitis can vary greatly depending on the severity of the condition and the individual's overall health. It's essential to follow a structured rehabilitation plan and adhere to professional medical advice to ensure proper healing and prevent re-injury.
Rehabilitation Timeline
Recovery time for patellar tendonitis varies based on the severity of the injury, overall health, and age of the individual, and the chosen treatment approach. Mild cases may allow a return to normal activities in 3 weeks, while severe cases may take 3 months or longer to recover. Persistent tendonitis can lead to ongoing knee pain that may limit certain activities.
Small or partial tears of the patellar tendon may require rest and rehabilitation exercises, while more serious injuries may necessitate the use of a knee brace for 3–6 weeks to immobilize the joint and allow the tendon to heal.

Importance of Physical Therapy
Physical therapy plays a vital role in the recovery process by restoring movement gradually, with strengthening and stretching exercises to be done at home. Physical therapists can help prevent re-injury by identifying the cause of the tendonitis, such as weak hips leading to the knees taking more impact during running or jumping, causing pain. By examining movement patterns, therapists can determine why tendons are being overloaded and recommend appropriate measures [3].
Recovery from patellar tendonitis can vary in duration and depends on individual factors. While some may start feeling better after a few weeks of rest, others with more severe cases may struggle with chronic pain. Rushing recovery can further damage weakened tendon tissues, so it's essential to allow enough time for healing.
In managing patellar tendonitis, initial treatments focus on symptom management and strengthening the soft tissues in the knee. Rest is often recommended as a conservative therapy, and in more severe or chronic cases, ultrasound and MRI imaging may be used to observe structural damage to the patellar tendon.
Overall, the key to a successful recovery is patience and dedication to the rehabilitation process. It's crucial to follow your doctor's instructions and work closely with your physical therapist to ensure you're not pushing yourself too hard and risking further injury. The right balance of rest, exercise, and therapy can help you regain strength and mobility, allowing you to return to your regular activities safely.
Preventing Patellar Tendonitis
While exploring patellar tendonitis treatment options is essential, prevention is always better than cure. Understanding the risk factors and implementing prevention strategies can help avoid the onset of patellar tendonitis, also known as jumper's knee.
Risk Factors
Patellar tendonitis is most commonly associated with sports that involve frequent jumping, such as basketball and volleyball. Repeated jumping motions can gradually strain the patellar tendon over time, leading to the condition. As a result, professional basketball and volleyball athletes are particularly susceptible to developing patellar tendonitis.
However, it's not just athletes who are at risk. According to the Mayo Clinic, individuals not participating in jumping sports can also develop patellar tendonitis. Any activity that puts stress on the knee, such as repeated jumping or knee flexion, can increase the risk of developing this condition.
Prevention Strategies
Preventing patellar tendonitis involves taking steps to reduce strain on the patellar tendon and keep the knee joint healthy. Here are some strategies recommended by the Mayo Clinic:
- Warming up properly: A proper warm-up before exercise prepares the muscles and tendons for the activity, reducing the chance of injury.
- Engaging in strength training: Regular strength training can help maintain leg flexibility and strength, providing better support for the knee joint.
- Using proper footwear: Wearing shoes that provide adequate support and cushioning can reduce the impact on the knee joint during high-impact activities.
- Avoiding sudden changes in training intensity: Gradually increasing the intensity and duration of training sessions can help the body adapt to the increased strain, reducing the risk of injury.
- Incorporating proper cool-downs and stretching: Cooling down after exercise and regular stretching can help maintain flexibility and prevent muscle tightness, which can contribute to knee strain.
By being mindful of these risk factors and implementing preventive measures, one can reduce the likelihood of developing patellar tendonitis.
