Longitudinal Tear of the Medial Meniscus Posterior Horn in the Anterior Cruciate Ligament–Deficient Knee Significantly Influences Anterior Stability

Abstract

These findings may help improve the treatment of patients with ACL and MMPH longitudinal tear by suggesting that the medial meniscal repairs should be performed for greater longevity when combined with an ACL reconstruction.

The role of the meniscotibial ligament in posteromedial rotational knee stability

“…Levy et al [6] found that tibial translation was greater in the ACL-deficient knee after total medial meniscectomy. Our results are consistent with the data available in the literature [1,11]. The PHMM seems to play an important role in limiting anterior tibial translation in the ACL-deficient knee [3].…”

Efficacy of Magnetic Resonance Imaging Evaluation for Meniscal Tear in Acute Anterior Cruciate Ligament Injuries

“…Through biomechanical or cadaveric studies, several authors reported that in an ACL-deficient knee, rotatory and shear force on the MMPH was increased with an increase in translation of the medial femoral condyle, which resulted in an MMPH longitudinal tear. [26][27][28][29] According to those studies, a high rate of secondary MMPH tears in patients with ACL deficiency may be possible, and in our study most of the missed MM tears in ACL-injured knees were MMPH tears. In an ACL-deficient knee, the possibility of an MMPH tear should be considered during the operation.…”

Correlation between time from injury to surgery and the prevalence of ramp and hidden lesions during anterior cruciate ligament reconstruction. A new diagnostic algorithm

“…Some Authors have stressed the role of meniscocapsular 13,14 and longitudinal 15 tears of the PHMM on the antero-posterior knee stability in anterior cruciate ligament-deficient knees. Despite its importance, the lack of identification of PH-MM lesions is the most frequent cause of mistakes in arthroscopic surgery of the knee [16][17][18] .…”
