Relationship of Acl Injury With Posterior Tibial Slope, Intercondylar Notch Width Ratio, Age, and Sex

Abstract

Posterior tibial slope (PTS) has been proposed as a potential risk factor for ACL injury; however, studies that examined this relationship have provided inconclusive and sometimes contradictory results. Further characterization of this relationship may enable the medical community to identify individuals at greater risk for ACL injury and possibly characterize an anatomic target during surgical reconstruction. Medical records of 20 patients who underwent MRI of the knee and athroscopy procedure between August 2016 and March 2017 were reviewed. Patients were separated into 2 groups: a study group of those subjects who had undergone surgery for ACL injury (n =10) and a control group of patients diagnosed without ACL Injury (n = 10). Demographic data were collected, and MRI images from both groups were analyzed using protactor android imaging software to obtain PTS measurements. Data then analyzed using SPSS v20. Data analysis demonstrated that the ACL injury group had significantly greater values for PTS (14.4 SD ± 3.5) compared with controls (10.1 SD ± 2.6). After stepwise elimination of non significant variables, the final t test independent determined that PTS (p value 0.08; p < 0.1) had statistically significant relationships with ACL injury. INW ratio, age, and sex were not demonstrated to be significant predictors of ACL injury in this final model. This study showed a relationship between increased PTS and ACL injury, which corroborates the findings of previously published studies. INW ratio, sex, and age showed no significant relationship with ACL injury.

Profile of Knee MRI Morphometric Risk Factors for Anterior Cruciate Ligament Tear at Dr. Soetomo General Academic Hospital

“…This finding is consistent with a study from Han et al, Andrade et al, Zeh et al, Shen et al, Volkan et al, Huang et al, Bayer et al, Priono et al study, where they reported a significant correlation between an increase in MTPS value with ACL tear incidence. 2,[9][10][11]13,15,18,26 They also found that the case group had a mean MTPS value of more than 14.4 degrees. 8 Between total and partial tear groups, it was found that NW, NWI, Q-angle and MTPS values were smaller in total tear group than in partial tear group.…”

“…Anterior Cruciate Ligament (ACL) tear is one of the most common knee ligament abnormalities found in athletes, its incidence ranges from 29-38 per 100,000 people. [1][2][3] As a result, in the short term it might cause instability and in the long term it might cause degenerative process of knee joint. The most common type of ACL injury mechanism is non-contact type, due to pivoting movement, when the knee is slightly flexed and in valgus position then the femur undergoes external rotation as in foot maneuver movement during ball dribbling.…”

“…However, various measurement techniques and methods of these anatomical factors are still debatable. 1,2,[9][10][11]13,[15][16][17]18 This study aims to provide an overview of anatomical risk factor characteristics in knee joint MRI study.…”

Perbandingan Efektivitas Pemberian Kinesio Tape Lutut Terhadap Knee Valgus pada Gerak Cutting Atlet Basket Tingkat SMA di Kota Malang

“…Selama cutting, atlet wanita menunjukan penurunan sudut fleksi hip, sudut knee valgus lebih besar daripada dengan pria. Hal ini menunjukan bahwa wanita lebih beresiko cedera ACL dibandingkan pria (Priono et al, 2018).…”

“…Karakteristik berdasarkan gender pada penelitian ini juga menunjukan tidak ada perbedaan yang signifikan knee valgus mempengahruhi risk of injury responden. Hal ini berlawanan dengan hasil penelitian sebelumnya bahwa wanita lebih beresiko terkena knee injury dibandingkan laki-laki dilihat dari biomekanika anggota gerak bawah ketika melakukan cutting manuver (Priono et al, 2018). IMT berdasarkan hasil yang didapat dalam penelitian ini menunjukan tidak terdapat pengaruh yang signifikan juga.…”
