At the time point of examination, the tendon graft condition was classified morphologically as follows: a grade I—good condition (no atrophy, clearly demarcated from the rest of the joint structures); b grade II—atrophic (decrease of the transplant diameter); c grade IIIa—distinctly atrophic (clear decrease of the transplant diameter, transparent); d grade IIIb—distinctly atrophic and in part highly covered fibrinously, difficult to delimit from the surrounding soft tissues)
