Where it strikes

Medical treatment

  • Prehabilitation then ACL reconstruction in pivoting athletes
  • conservative rehab works for many
  • meniscal repair over removal
  • 9–12 month return to sport
  • bridge-enhanced ACL repair (BEAR implant) — FDA-authorised 2020; long-term results still few

Natural & lifestyle

  • Neuromuscular training programmes prevent 50% of ACL tears
  • quadriceps and hamstring strengthening
  • landing technique
  • graded return

Emerging & experimental

  • Meniscal scaffolds
  • cross-bracing protocol (healing without surgery)

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • Collagen with vitamin C before rehabilitation sessions — small studies of better ligament repair early / small studies
  • Stem-cell injections for a torn ACL — marketed widely; unproven anecdotal / traditional
