Patellar Tendinopathy

This article is a stub.

Pathophysiology

Proximal patellar tendinopathy is much more common than distal.

In some cases there may be a rheumatological cause with insertional patellar tendinopathy especially spondyloarthropathy. In this setting there may be associated bursal changes.

Treatment

PRP

No benefit for leukocyte rich or leukocyte poor PRP injections over saline.

Exercise Therapy

Eccentric Strengthening

One of the most effective and widely used treatments Important considerations

• The exercises are painful, this is normal
• Large numbers of repetitions every day required – between 90-180
• Minimum of 3 months

Eccentric loading squats on a 25 degree decline board (3 x 15, twice daily, for 3 months) Alternatively can ddo gym based “HSR” (heavy slow resistance – eccentric-concentric isotonic)

Isometric Exercises

Possibly reduces pain but original study results (n=20 study) could not be replicated = isotonic as effective (n=21 replication study) . May be useful pre-activity intervention or early on. Silbernagel et al note:

“The argument for the benefit of isometric exercise is that it causes immediate pain relief and the recommendation is that progression to other exercise should not be pursued until pain has settled and the patient is proficient at isometrics.3 This ignores previous evidence in support of using isotonic exercise as the initial stage for tendinopathy treatment. Pain during exercise has not been found detrimental for recovery and to the contrary might even be beneficial”
