Introduction

There is no consensus on the optimal treatment of partial tears in the anterior cruciate ligaments (ACL). Radiofrequency (RF) has been used to treat ACL partial tears. This treatment can be detrimental to ACL strength.

Objective

To evaluate the ultimate failure at maximum load (UFML) of porcine ACL with partial tears.

Methods

Two groups were evaluated, N = 40, A control and B treated with RF. Samples were placed in a PASCO^庐 universal traction machine and axial continuous tension was applied until failure; documenting necessary strength in Newtons (N) to produce UFML.

Results

UFML for A: 1951,9 N (1144-2688) and B: 1457,1 N (1070-2025) (P鈮?001).

Conclusion

RF use for single bundle ACL partial tears treatment compromises the UFML when compared to single bundle ACL parcial tears without RF.
