“…Meanwhile, skeletal muscle and ligament injuries cause a shortage of oxygen supply and damage to the adjacent capillaries, which leads to QF atrophy ( 37 , 38 ). Previous studies showed an interaction between joint pain and QF atrophy, which might worsen with each other ( 39 , 40 ). In the present study, the patients who underwent MHI received frequent training reminders, which led to better performance in reducing QF atrophy.…”

ObjectiveThis study aimed to assess changes in joint range of motion (ROM) and knee joint function between patients who received the mobile health-based intervention and those who received regular care at 2 and 6 weeks after anterior cruciate ligament (ACL) reconstruction to provide better interventions in the future.MethodsPatients who underwent ACL reconstruction were randomized into the experimental [Mobile health-based intervention (MHI); n = 62] and control (CON) groups (n = 63). The CON group underwent home-based rehabilitation exercise following the paper rehabilitation schedule, while the intervention group received additional mobile health-based education at weeks 1–6 after surgery. ROM, thigh circumference difference, and flexion pain were the primary outcomes. The secondary outcomes were the international knee documentation committee knee evaluation form (IKDC) scores and rehabilitation compliance scores. All the outcomes were measured 1 day before surgery as references and at 2 and 6 weeks after surgery.ResultsThere was no statistical difference in the patients' ROM, thigh circumference difference, and VAS scores at the 2-week follow-up. At the 6-week follow-up, the ROM of the affected leg was (118.1 ± 20.5)° in the CON group and (126.6 ± 20.5)° in the MHI group, and the difference was statistically significant (P = 0.011). The difference in thigh circumference was 3.0 (2.0, 3.5) cm in the CON group and 2.5 (1.0, 3.0) cm in the MHI group. The difference was statistically significant (P < 0.001). The VAS score in the CON group was 3.0 (2.0, 4.0), and the MHI group was 2.5 (1.0, 3.0). The difference was statistically significant (P < 0.05). At the 6-week follow-up, the compliance score of patients in the MHI group was significantly higher than that in the CON group (P = 0.047, β = 2.243, 95%CI: 0.026–4.459). There is no statistically significant difference in IKDC scores.ConclusionMobile health-based intervention positively affected patients undergoing ACL reconstruction surgery, particularly in improving the clinical outcome indicators of the knee joint.

“…This study is one of the first studies investigating the relationship between single-bundle hamstring autograftused ACL reconstruction and patellofemoral balance (10)(11)(12)(13)(14)(15)28). The strength and most important finding of our study is the low incidence of patellofemoral problems in the one-year follow-up of patients after single-bundle On the other hand, the very low rate of the decrease in IS index (from 1.08 to 1.02) raises doubts about whether our finding, although statistically significant, will be clinically effective.…”

“…Although the relationship between ACL reconstructions and many different conditions such as meniscal tears, cartilage degeneration, and trochlear dysplasia has been investigated in the literature, the relationship between ACL reconstruction and patellar height disorders has been studied only in a limited number of studies, to the best of our knowledge (10)(11)(12)(13). On the other hand, considering the important role of the anterior cruciate ligament in the balance of the knee and the effects of autografts used in ACL reconstruction on patellar or quadriceps tendon lengths, it is a reasonable hypothesis that there is a relationship between ACL reconstruction and patellar height (14,15).…”

Background: Considering the critical role the anterior cruciate ligament (ACL) plays in knee biomechanics, it is a logical hypothesis that ACL reconstruction (ACLR) will have positive effects on knee kinematics, and stability. Our objective was to investigate the effect of single-bundle ACLR on patellar height, and patellofemoral balance radiologically and clinically. Methods: In this prospective study, 87 patients operated with hamstring autograft-used single-bundle ACLR were analyzed. History of dislocation, stability-related physical examination findings, Tegner-Lysholm Knee Scoring Scale, and Kujala Anterior Knee Pain Scale were used for functional assessment. All patients underwent pre-and post-operative magnetic resonance imaging and Insall-Salvati (IS) Index, Caton Deschamps Index, Blackburne-Peel Index, and Patella-patellar tendon (P-PT) angles were measured on T1-weighted sagittal section images. Results: A total of 79 patients (90.8%) achieved excellent or good result, according to Tegner-Lysholm Knee Scoring Scale, and the patients' postoperative 1st year mean Kujala Anterior Knee Pain Score was calculated as 90.4 (Range: 79.1 – 96.4). On physical examination, increased passive patellar translation was observed in 2 patients (2.3%), but the J sign was appeared to be negative in all the patients. While all patellar height indices decreased after reconstruction, only the decrease in IS index was statistically significant (p=0.007). Moreover, the P-PT angle was found to be significantly lower after ACLR (p

“…The changes in contact pressure in the tibiofemoral and patellofemoral joints depend on the ACLR surgical technique [19] and on the presence of a meniscal injury [16], which could subsequently cause cartilage degeneration. In addition, rehabilitation without sufficient quadriceps muscle strength can cause patellofemoral maltracking, which can further result in cartilage microdamage [4]. The factors associated with joint effusion after ACLR need to be evaluated from a multidisciplinary perspective, and include surgical factors, intra‐articular lesions, muscle strength, and rehabilitation goals.…”

Purpose To evaluate whether joint efusion at 3 months after anterior cruciate ligament (ACL) reconstruction is associated with ACL reinjury. Methods The medical records of 227 consecutive patients who underwent single-bundle ACL reconstruction between 2015 and 2018 were reviewed in this retrospective single-center study. Demographic data such as sex and age at surgery, as well as data on preinjury Tegner activity scale score, time from injury to surgery, presence of meniscus and cartilage injuries, and the occurrence of ACL reinjury within 2 years, were collected. Joint efusion was deined as grade 3 (range 0-3) according to the ACL Osteoarthritis Score by magnetic resonance imaging at 3 months postoperatively. Multivariate logistic regression analysis was performed to control for potential confounders. Results A total of 176 patients (mean age 22.5 ± 9.9 years) were included. Among these patients, 18 (10.2%) had ACL reinjury. At the multivariate logistic regression analysis, higher Tegner activity scale (odds ratio [OR] 3.12; 95% conidence interval [CI] 1.61-6.04; p < 0.001) and presence of joint efusion (OR 34.5; 95% CI 6.63-179.7; p < 0.001) increased the odds of ACL reinjury, and older age (OR 0.68; 95% CI 0.51-0.92; p = 0.012) decreased the odds of ACL reinjury. Conclusions Joint efusion with a larger luid volume at 3 months postoperatively was one of the risk factors for ACL reinjury independent of confounders, such as age and activity level. This result suggests the possibility of postoperative intervention for ACL reinjury. Level of evidence III.
