Which OKC are you using in the early lower limb rehabilitation?
New study 🔰The Effect of Open vs Closed Kinetic Chain Exercises on Anterior Tibial Laxity, Strength, and Function Following Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis.
Perriman A, et al. J Orthop Sports Phys Ther. 2018.🔰
➡️494 participants, (Mean age 19-34 year)
➡️ N=10 studies compared CKC exercises with either
- solely OKC exercises (seven studies)
- a combination of OKC and CKC exercises (three studies).
- OKC (or combined OKC and CKC) exercises were introduced early (less than six weeks) (6 studies)
- 4 studies they were introduced OKC later (greater than six weeks)
4 reported on adverse events.
- 1 study reported no adverse events.
- 1 study (100 participants) reported 2 graft failures in the early OKC group less than 3 months postoperatively) (see the CKC and OKC protocol),
- 1 one study reported 2 graft failures in each group.
- 1 study reported the requirement for 2 follow up 340 arthroscopes but were not clear in which groups these adverse events occurred

There was limited to moderate evidence of no significant difference in clinically important anterior tibial laxity, strength, patient reported function or physical function with the early introduction of OKC exercises in the ACLR population when compared to CKC exercises at all follow up time points. The hamstrings graft may potentially be more vulnerable to laxity than the patellar graft, but this is based on limited evidence.
✅Exercise protocols which made up the interventions varied between studies (online Appendix 2). However for both groups there was some common exercises.
