Kobe Bryant has returned to Germany for medical treatment on his right knee, not on his surgically-repaired Achilles’ tendon.

Bryant will undergo platelet-rich plasma treatment, Yahoo’s Adrian Wojnarowski reports. He had PRP, also known as Orthokine or Regenokine, on his right knee and left ankle in 2011. The Los Angeles Lakers said they expect Bryant back early next week and that his Achilles’, which was surgically repaired last April, will not be treated.

“I don’t think it’s a surprise,” Coach Mike D’Antoni said (via ESPN). “I think he had it programmed, and just the way it was, he knew he had time because he’s not getting on the court yet. So I don’t think it’s a big deal, and I don’t think it caught him by surprise. Instead of doing it in August, he’s doing it now.

“There’s no concern whatsoever.”

PRP involves taking blood from a patient, spinning it in a centrifuge to separate platelet-rich plasma and injecting it into the targeted site. Platelets stimulate growth and blood flow to the area of injury or discomfort.
