Background/Purpose: Patellar tendinopathy, or jumpers knee, is very common among elite athletes who participate in sports that involve jumping and quick directional changes. Several different therapies and modalities have been experimented with to increase the healing of the tendon. The purpose of this case study and review is to evaluate the effectiveness of platelet-rich plasma injection therapy on treating refractory long-term patellar tendinopathy. Case Description: Subject is a 28y/o male with an 11-year history of knee pain with confirmed patellar tendinopathy via MRI. He is currently active military with high activity job requirements. Subject has previously undergone extensive physical therapy including a series of cortisone injections. Subject experienced temporary relief, but symptoms continue to return. He considered decompression surgery of the patellar tendon, but instead opted for the platelet-rich plasma (PRP) injection treatment. Outcomes: At initial physical therapy evaluation 3 weeks post injection, patient reported that he has avoided any type of running, jumping, and resistance training since the injection and estimated an 80% improvement in his function and pain. Patient has now undergone physical therapy for 5 weeks and has returned to his physician for a 2-month follow-up. The MRI results showed a decrease in irregularity of the tendon and the subject reported a complete resolution of pain and has been released to begin higher intensity physical therapy training. Discussion: The symptoms of patellar tendinopathy can be life altering and hindering. There are many different types of conservative treatment methods. However, most of these methods are poorly researched. PRP injection treatment looks to be a promising intervention for the healing process of the patellar tendon resulting in a decrease in pain and allowing for an increase in function.
