ACL Surgery
Once torn, it doesn’t heal. Reconstruction does not make it normal – posttraumatic osteoarthritis can occur regardless of management
Surgical vs non-surgical management
- RCT of 121 “young active adults”
- Rehab (plus delayed surgery if needed) vs rehab plus early surgery
- 5 year follow up: no differences in ability to return to sport, knee function, or rate of meniscal injury
- 50% crossover (50% in rehab group crossed over to surgery)
- Take-away: 50% can be managed non-operatively
- In my opinion we don’t know if those other 50% eventually managed operatively would have better outcomes than sham surgery
Subsequent OA and Meniscal Tears
- Metanalysis 2019, comparing surgery vs non-surgical treatment with 10 year follow up
- Patient reported outcomes the same
- Higher rate of radiographic knee OA
- Lower rate of secondary meniscal injury and meniscal surgery
- Reduced laxity
- Significant methodological flaws in the included studies and heterogeneity
Copers vs non-copers
- Copers – use neuro-musculo-skeletal strategies to dynamically stabilise their ACL-deficient knee even with pivoting
- Non-copers – knee instability, higher rates of surgery
- Not possible to classify this early on
- in one study 70% of those initially classified as non-copers, were copers after 1 year of non-operative management. And only 60% of potential copers were true copers.
ACL Reconstruction
- Indications??
- Recurrent instability
- Associated tear when amenable to repair
- Associated ligament injury especially posterolateral corner
- Professional and elite players
- High-risk occupation (where instability could cause harm)
- ?Adolescents, risk of instability, ?protect against future meniscal and chondral damage.
- Delay surgery until normal range of motion, effusion largely resolved and able to walk comfortably (to reduce risk of athrofibrosis i.e. stiffness)
ACL Graft Selection
- Bone-Patella-Bone
- possible earlier graft fixation and stability due to included portion of bone
- anterior knee pain up to 1 year
- possible higher rate of OA.
- Hamstring
- Initial fixation may be slower and weaker (no bone), but quadruple strand is stronger than B-P-B
- Donor site pain resolves by 3 months
- hamstring strength normal by 12 months.
- Other: Allografts, quadriceps graft,
ACL Postoperative
[4] Graft re-rupture (from surgical failure or re-trauma) Outcomes worse for revision ACL repair Increased risk tear contralateral knee – 7% cumulative incidence 5770 reconstructed knees – 60% returned to pre-injury level, and 44% returned to competitive sport. Professional players – 90% return to play by 12 months, sensible?? Shorter careers.
Unknown Unknowns
- Cultural norms in professional sport and other areas
- ?Uncertainty of non-operative treatment
- Loss of option of early ACL repair
- ACL-deficient sport ?future meniscal and cartilage injury
- What is success, return to pivoting sport? What is in the athlete’s best interest?
- “Doing nothing” is hard
Rehabilitation for Athletes
- Protection and controlled mobilisation
- Controlled training
- More intensive training
- Return to play (many months)
