Jannik Sinner is struggling with a knee injury; his doctor speaks out

In recent days, Jannik Sinner visited a clinic in Milan to undergo tests on his knee, which had already been treated in recent weeks at J Medical in Turin. Initially, it appeared to be a routine visit; in reality, the tests were not scheduled, but at this time, there is no cause for alarm.

Andrea Bernetti, full professor of Physical and Rehabilitation Medicine at UniSalento and secretary general of SIMFER (Italian Society of Physical and Rehabilitation Medicine), also commented on the world No. 1’s condition: “While we cannot comment on the specific condition of the athlete, we can say that when a tennis player experiences a knee problem without having suffered an acute injury—as appears to be the case with Sinner—we are likely dealing with an overuse injury,” he told Adnkronos Salute.

“The overload could be caused by the constant stress, jumping, sudden stops, sliding, and abrupt changes in direction required by modern tennis. His staff’s decision appears to be the right precaution to avoid overloading the knee, thereby allowing him, on the one hand, to manage the load and, on the other, to undergo a dedicated therapeutic protocol to reach the best possible condition,” the doctor continued.

Regarding treatment options, Professor Bernetti suggested “hydrokinetic therapy (therapeutic exercise in water), instrumental physical therapy (focal shock waves, pulsed electromagnetic fields, laser therapy), and infiltration therapy using hyaluronic acid, platelet-rich plasma (PRP), collagen, or ozone therapy. All of these options must be evaluated on a case-by-case basis according to the diagnosis and characteristics of each individual athlete.”
