"How Long Does It Take For Jumpers Knee To Heal?
This will depend on the degree of damage to the tendon but typically
once the correct treatment has started a period of 2-3 months will allow good tissue healing and strengthening. Even if the tendon hasn’t fully healed by this stage, it should be ready to do some higher impact activity again. In some mild cases, sport can be continued whilst the tendon is being treated and it can be managed carefully without it worsening, but
in more severe cases the tendon will need complete rest and could take as long as 6-9 months to fully heal."
