Purpose: Anterior Cruciate Ligament (ACL) injury is the most common knee ligament injury during exercise, with a frequency of 36.9 per 100000 individuals. The characteristics of this injury are proprioception dysfunction. The present study aimed to investigate the knee proprioception after the reconstruction of ACL in soccer players. Methods: The study sample of this study was 20 elite male soccer players with an ACL injury experiencing post-reconstruction. The knee joint position sense of the study subjects was measured by Isokinetic (Gymnex model) at 30°, 45°, and 60° between the operated and non-operated knee. An Independent Samples t-test was used to compare the mean scores of the measured variables at the significance level of P≤0.05. Results: The obtained results suggested that the mean value of the angle reproduction test at 30° on the operated knee was significantly more than that of the non-operated knee (P=0.003). Moreover, the mean value of a passive angle reproduction test was significantly more than that of the active angle test in the operated knee (P=0.001). There was no significant difference between the mean value of 45° angle repair results in the non-operated and operated knee (P=0.99). The difference between active and passive tests in the operated knee on 45° was significant; the study subjects demonstrated higher mean scores in the active test (P=0.02). Additionally, the half-value in angle reproduction in 60° in the operated knee was significantly less than that of the non-operated knee (P=0.01). Eventually, there was no significant difference between the results of the test at this angle in the passive and active angle reproduction in the affected knee (P=0.22). Conclusion: The obtained data revealed that the knee joint position sense of the operated knee joint, compared to the non-operated knee in elite soccer players, along with the reconstruction of the ACL, was weaker than those of the non-operated knee.

Research  background  and  hypothesis.  Proprioception  is  important  in  the  prevention  of  injuries  as  reduced proprioception  is  one  of  the  factors  contributing  to  injury  in  the  knee  joint,  particularly  the  ACL.  Therefore, proprioception appears not only important for the prevention of ACL injuries, but also for regaining full function after ACL reconstruction.Research aim. The aim of this study was to understand how proprioception is recovered four and five months after anterior cruciate ligament (ACL) reconstruction.Research methods. The study included 15 male subjects (age – 33.7 ± 2.49 years) who had undergone unilateral ACL reconstruction with a semitendinosus/gracilis (STG) graft in Kaunas Clinical Hospital. For proprioceptive assessment, joint position sense (JPS) was measured on both legs using an isokinetic dynamometer (Biodex), at knee flexion of 60° and 70°, and at different knee angular velocities of 2°/s and 10°/s. The patients were assessed preoperatively and after 4 and 5 months, postoperatively.Research results. Our study has shown that the JPS’s (joint position sense) error scores  to a controlled active movement is significantly higher in injured ACL-deficient knee than in the contralateral knee (normal knee) before surgery and after four and five months of rehabilitation.  After 4 and 5 months of rehabilitation we found significantly lower values in injured knees compared to the preoperative data. Our study has shown that in injured knee active angle reproduction errors after 4 and 5 months of rehabilitation were higher compared with the ones of the uninjured knee. Proprioceptive ability on the both legs was  independent of all differences angles for target and starting position for movement. The knee joint position sense on both legs depends upon the rate of two different angular velocities and the mean active angle reproduction errors at the test of angular velocity slow speed was the highest compared with the fast angular velocity. Discussion and conclusions. In conclusion, our study shows that there was improvement in mean JPS 4 and 5 months after ACL reconstruction, but it did not return to normal indices.Keywords: knee joint, joint position sense, angular velocity, starting position for movement.

This study evaluated knee joint position sense in the ACL-reconstructed and contralateral normal knees of 48 male and female subjects (M age 27.6 ± 6.9 yrs). Subjects were blindfolded and tested on their ability to actively reproduce five passively placed knee positions at 5° intervals between 35 and 15° of knee flexion. Mean algebraic target angle error and mean absolute error values were measured in degrees. The grand mean absolute error for the postsurgical knees at all positions was 5.4 ± 3.2°, compared with 5.2 ± 2.7° for the normal contralateral knees. There were no significant differences in knee joint position sense between the postsurgical and normal contralateral limbs at any of the five positions tested. Pivot shift, anterolateral rotatory instability, and Lachman test results were poorly correlated with knee joint position sense. The results suggest that if knee joint position sense was indeed disrupted by ACL injury and reconstructive surgery, related sensory mechanisms compensated for any proprioceptive loss prior to the minimum 2-yr postsurgical follow-up period employed in our study.

It is estimated that approximately 350,000 individuals undergo anterior cruciate ligament (ACL) reconstruction surgery in each year in the US. Although ACL-reconstruction surgery and postoperative rehabilitation are successfully completed, deficits in postural control remain prevalent in ACL-reconstructed individuals. In order to assist the lack of balance ability and reduce the risk of retear of the reconstructed ACL, physicians often provide a functional knee brace on the patients’ return to physical activity. However, it is not known whether use of the functional knee brace enhances knee-joint position sense in individuals with ACL reconstruction. Thus, the effect of a functional knee brace on knee-joint position sense in an ACL-reconstructed population needs be critically appraised. After systematically review of previously published literature, 3 studies that investigated the effect of a functional knee brace in ACL-reconstructed individuals using joint-position-sense measures were found. They were rated as level 2b evidence in the Centre of Evidence Based Medicine Level of Evidence chart. Synthesis of the reviewed studies indicated inconsistent evidence of a functional knee brace on joint-position improvement after ACL reconstruction. More research is needed to provide sufficient evidence on the effect of a functional knee brace on joint-position sense after ACL reconstruction. Future studies need to measure joint-position sense in closed-kinetic-chain fashion since ACL injury usually occurs under weight-bearing conditions.

Objectives: The purpose of this study was to design and assess the outcomes of the new lightened rehabilitation program after anterior cruciate ligament reconstruction (ACL-R). Methods: Thirty-two of the 57 patients with ACL-R using tibialis anterior grafts completed the study. The patients in the lightened rehabilitation program were compared with patients in standard rehabilitation program. The two groups were assessed using International Knee Documentation Committee (IKDC) and Lysholm scores, isokinetic knee muscle strength, knee joint position sense, and hop test. Results: There were no significant differences in muscle strength of the quadriceps and hamstring at 60°/s, 180°/s, and 330°/s between the operative and non-operative side in the lightened rehabilitation group while there was significant difference in muscle strength of the quadriceps and hamstring at 60°/s between the operative and non-operative side in the standard rehabilitation group. There were significant differences in muscle strength of the quadriceps and hamstring at 330°/s and joint position sense at 75°, 45°, and 15°between the operative side of the patients in lightened rehabilitation group and operative side of the patients in standard rehabilitation group. There was no difference in the knee joint position sense at 15°, 45°, and 75°, between the operative and non-operative side in the both groups. Conclusion: Clinical relevance of this study is that the new lightened rehabilitation program should be also succeeding as much as standard rehabilitation program after ACL-R. It is suggested that future studies might evaluate the effects of the new lightened rehabilitation program for different grafts and professional athletes.
