What is patella tip syndrome?

Patella tip syndrome is a chronic inflammation of the patellar tendon’s insertion point on the kneecap. It usually occurs after excessive strain and can be accurately diagnosed because the pain is clearly located at the lower patella tip and can be easily reproduced during an examination.

Patella tip syndromeis divided into four levels. At the first level, pain occurs exclusively after heavy strain. At the second level, pain occurs at the beginning of and after strain. At the third level, the pain is constant. At the fourth level, the patellar tendon will tear.

Patella tip syndrome is the most common knee condition in elite athletes and aspiring amateur athletes. Sports with high tensile loads on the patellar tendon, such as during jumping or shock absorbing, are particularly prone to patella tip syndrome. In addition to high jump and long jump, this also includes ball sports such as volleyball and basketball as well as weight lifting and endurance running on hard surfaces.

Location of the pain

Patella tip syndrome is an inflammation of the tendon that connects the thigh muscle with the shin (tibia) via the kneecap (patella). It occurs at the lower end of the kneecap directly on the transition between patellar tendon and patella.

Patella tip syndrome has many names

Most people probably know patella tip syndrome (PTS) by the colloquial description “jumper’s knee.” The technical terms patellar tendinitis, patellar tendinosis, enthesiopathy and patellar tendinopathy are also used.

Causes of patella tip syndrome

Patella tip syndrome is caused by chronic excessive strain on the tendon insertion point. The strain is strongest when the knee is bent because the tendon insertion point is flexed and tensed.

Three areas can generally be involved in triggering patella tip syndrome: the active musculoskeletal system (muscles and tendons), the passive musculoskeletal system (bones, joints and ligaments) and the individual body posture.

Excessive strain

Especially when landing after a jump, a maximum tensile load is applied to the kneecap In addition to the intensity, the frequency of the strain and the individual’s physical condition play an important role.

Tensile forces caused by imbalances

A congenital ligament weakness, shortened or hardened thigh muscles, a shorter leg or other physical imbalances can increase the tensile forces that are exerted on the patellar tendon.

High-riding patella

In the case of high-riding patella, also known as patella alta or high-riding kneecap, the kneecap has shifted upwards, thus exerting increased tensile forces on the patellar tendon when the knee is bent. High-riding patella can be congenital or acquired.

Misalignment (of the patella)

If the kneecap shifts outwards, additional strain is applied, which can result in problems.

Comprehensive treatment of patella tip syndrome

To lay the foundation for successful treatment of patella tip syndrome, it’s firstly important to stop whatever is causing the strain. Depending on the intensity, a break of six to twelve weeks is recommended before starting to train again.

Treatment with medical products

In the case of chronic or acute pain, a patella strap, such as the JuzoFlex Patella Xtra, helps to guide and stabilise the kneecap. The massage effect exerted by the nubs promotes blood circulation and therefore the healing process. If the cause of patella tip syndrome is a foot misalignment, orthopaedic insoles can compensate for imbalances. In severe cases, an orthosis such as the JuzoPro Patella Xtec provides additional stability, making it even more effective.

Treatment with the JuzoFlex Patella Xtra

The best treatment for patella tip syndrome

The JuzoFlex Patella Xtra is used in the conservative treatment of patella tip syndrome. Its main aims are pain reduction and support of the regeneration process. A pad centres the kneecap, therefore improving its guidance. The stimulating and massaging effect of the nubs boosts the healing process.

Treatment of patella tip syndrome can take up to 16 weeks. It requires a lot of patience and co-operation from the patient. If the treatment of patella tip syndrome is prematurely discontinued, the condition can become chronic. That’s why consistent treatment with the JuzoFlex Patella Xtra, supplementary measures and exercises for rehabilitation are essential.

Physical therapy

Depending on the level, pain pattern and indication, various types of physical therapy are used for patella tip syndrome. In addition to massages and physiotherapy, other options are thermotherapy, electrotherapy, ultrasound and shock wave therapy. The individual measures can be arranged and combined depending on the cause.

Movement

In order to reduce strain on the tendon insertion point, sporting activities that feature jumps or other extreme or frequent tensile loads should be avoided. To strengthen the supporting muscles, you and your doctor should discuss switching to gentler exercises, such as cycling or aqua jogging. Regularly stretching of the thigh muscles can reduce tension on the kneecap, while other targeted exercises can compensate for imbalances.

Eccentric exercises are particularly suitable during training. They contract the muscle quickly. Muscle tension generated in this way is relieved slowly and in a controlled manner during the eccentric phase.

Exercises for strengthening and prevention

The patella strap improves the physiological guidance of the patella, thus promoting pain-free mobility. Tailor-made exercises help to strengthen the supporting muscles and compensate for imbalances. Juzo has collated the following selection of exercises in cooperation with therapists.

Level 1: Movement control

Exercise 1: Step-up

A woman standing in front of an aerobics step — **Step-up: Step 1**

A woman putting her right leg on an aerobics step — **Step-up: Step 2**

A woman standing on an aerobics step with both legs — **Step-up: Step 3**

Stand with your feet hip-width apart, in front of an exercise step or a similar stable object (ca. 20 cm). With a controlled movement, climb onto the step. Ensure that the knee doesn’t go further than your toes.

3 x approx. 15 to 20 repetitions on each side

Exercise 2: Seated diagonal movement

A woman, with one leg bent, sitting on a chair — **Seated diagonal movement: Step 1**

A woman, with one leg extended, sitting on a chair — **Seated diagonal movement: Step 2**

Sit on a chair, with your legs bent at a 90° angle. Raise one leg towards your chest, with your toes rotated inwards. Extend your leg and rotate your toes as far outwards as possible.

3 x approx. 15 to 20 repetitions on each side

Level 2: Co-ordination

Exercise 1: Squats with different leg angles

A woman standing upright with arms in front of her chest — **Squats with different leg angles: Step 1**

A woman doing squats with arms in front of her chest — **Squats with different leg angles: Step 2**

Stand with your legs about shoulder-width apart, feet slightly turned outwards. Important: Your knees and toes must always point
in the same direction. Bend your knees slowly (your buttocks move backwards) and then return to the starting position.

3 x 10 to 15 repetitions

Exercise 2: Split-squats

A woman doing a lunge forwards on a soft cushion — **Split-squats: Step 1**

A woman doing a lunge, lowering her back leg to just above the ground — **Split-squats: Step 2**

Take a big step forwards in a straight line. Bend the back knee. Ensure that the knee doesn’t go further than your toes.

3 x 10 to 15 repetitions on each side

Level 3: Strengthening

Exercise 1: Wall-sit

A woman leaning upright against a wall with an exercise ball — **Wall-sit: Step 1**

A woman leaning against a wall with an exercise ball, doing a squat with one leg extended — **Wall-sit: Step 2**

Stand with your back against a wall (ideally with a soft ball). Slowly squat down whilst extending one leg forwards in a flowing movement.
