Quadriceps weakness associates with greater T1 ρ relaxation time in the medial femoral articular cartilage 6 months following anterior cruciate ligament reconstruction

ConclusionsThe association between weaker quadriceps and greater T1 ρ relaxation times in the MFC suggests deficits in lower extremity muscle strength may be related to cartilage composition as early as 6 months following ACLR. Maximizing quadriceps strength in the first 6 months following ACLR may be critical for promoting cartilage health early following ACLR.Level of evidencePrognostic level 1.
