2. Injuries in Younger Patients Why are kids tearing their ACLs at such a young age?
Increasing number of children playing organized sports at a younger age
Correlates with the increasing number of ACL injuries
3. Treatment Options Conservative treatment:
Bracing
Physical therapy to strengthen the quadriceps and hamstrings
Counseling
Activity modification
4. Treatment Options Conservative treatment:
Various authors have reported poor outcomes with non-operative treatment
Bracing may not prevent instability
Further episodes of instability will most likely result in new meniscus tears and early arthritis
5. Treatment Options Primary repair:
May be attempted if ligament is avulsed from femoral or tibial insertions – may heal to provide temporary stability
Repair of midsubstance tears has resulted in persistent instability and decreased activity level
6. Treatment Options Extraarticular tenodesis:
May provide anterior tibial stability and eliminate the pivot shift
Not an anatomic reconstruction
Overloaded lateral joint compartment may undergo premature degenerative changes
7. Treatment Options Intra-articular reconstruction:
Should be avoided in young patients with open growth plates
Involves drilling through growth plates, which may cause physeal injury and growth arrest
8. The Million $$$ Question: What is the best option for a patient with a torn ACL and open growth plates?
ACL Repair with Semitendinosus Augmentation
9. The New Technique Semitendinosus is detached proximally, remains intact at the insertion
Passed under the intermeniscal ligament, running alongside the remaining stump of the ACL
Passed over the top of the femur
Held in place with screw and ligament washer proximal to physis
10. The New Technique
Clinical Orthopaedics, George A. Paletta, and Carl L. Stanitski; Ch. 63, p.779
11. The New Technique
Three #1 PDS sutures are passed through the remaining stump of the ACL
12. The New Technique ACL stump is freed up from adhesions to PCL, to increase excursion
13. The New Technique
Gaffe is introduced into the lateral portal, passed intra-articularly to locate the over-the-top position
Skin incision made over the gaffe
IT band is split
14. The New Technique Double-looped passing suture is placed through the gaffe and brought out through the medial portal
15. The New Technique
Sutures from the ACL are then brought out through a cannula placed in the medial portal
ACL sutures are then passed through the double-looped passing suture to the over-the-top position
16. The New Technique Incision is made over the hamstrings, semitendinosus is harvested
17. The New Technique 2-0 Ticron is placed through the detached proximal end of the semitendinosus
A 60° suture passer containing the Tycron is placed through the incision and under the intermeniscal ligament into the knee joint
18. The New Technique
19. The New Technique The harvested semitendinosus is then pulled through the knee joint, also to the over-the-top position alongside the remaining stump of the ACL
20. The New Technique The graft and sutures are tied down over a 6.5mm screw and spiked ligament washer
21. The New Technique Graft in full extension:
22. After Surgery Typically 3-5 days on crutches
Physical therapy is initiated as soon as possible after surgery
Most patients report less pain after ACL repair with semitendinosus augmentation than with traditional intra-articular ACL reconstruction
23. Results Since 1993, 13 patients have undergone this procedure
No growth arrest or angular deformity is present post-operatively
100% of patients have returned to pre-injury activities
24. X-rays Pre-op Post-op
25. Graft at Later Arthroscopy Initial surgery 1 year later
26. Case Study 12-year old female gymnast falls off balance beam, tears her ACL
Growth plates wide open on x-ray
Undergoes successful ACL repair with semitendinosus augmentation
27. Case Study Same female, now age 14, tears her ACL in opposite knee running bases
Growth plates are now closed
Undergoes traditional ACL reconstruction with bone-tendon-bone autograft
28. Comparative X-rays 12 years old 14 years old
29. Case Study Comparing knees, patient reports:
Easier recovery and quicker return to activity with repair
Equal strength bilaterally
Full range of motion bilaterally
Equal stability bilaterally
30. Summary
ACL repair with semitendinosus augmentation is a safe and effective procedure in patients with a torn ACL and open growth plates
