“…Kang et al, 2012, reported that isokinetic strength, isokinetic endurance, and squat strength improved significantly after both interventions ( p < 0.05), but changes in isokinetic strength and isokinetic endurance of the extensor muscles were significantly greater in the OKC group than the CKC group ( p < 0.05) [ 12 ]. In contrast Morrisey et al, 2000, found no difference between groups [ 11 ].…”

Background There is no consensus on whether closed kinetic chain (CKC) or open kinetic chain (OKC) exercises should be the intervention of choice following an anterior cruciate ligament (ACL) injury or reconstruction. Methods A systematic search identified randomized controlled trials of OKC versus CKC exercise training in people who had undergone ACL reconstructive surgery. All published studies in this systematic review were comparisons between OKC and CKC groups. Results Seven studies were included. Lysholm knee scoring scale was not significantly different between OKC and CKC exercise patients: MD: −1.03%; CI: −13.02, 10.95; p value = 0.87 (Chi2 = 0.18, df = 1, and p value = 0.67). Hughston clinic questionnaire scores were not significantly different between OKC and CKC exercise patients: MD: −1.29% (−12.02, 9.43); p value = 0.81 (Chi2 = 0.01, df = 1, and p value = 0.93). Conclusions While OKC and CKC may be beneficial during ACL surgical rehabilitation, there is insufficient evidence to suggest that either one is superior to the other.

“…Isokinetic strength and endurance were measured using a CSMI isokinetic dynamometer (CSMI Medical solution, Stoughton, MA, USA). Knee strength was measured through the range of 0 to 90° at an angular speed of 60°/sec, with four repetitions completed at an angular speed of 180°/sec, with 20 repetitions completed to calculate average power 10 ) . The highest peak torque value for each velocity was compared with the uninjured side and described as percent of strength deficit.…”

[Purpose] After an anterior cruciate ligament injury and subsequent reconstruction, quadriceps muscle weakness and disruption of proprioceptive function are common. The purpose of this study was to examine the effects of a 4 weeks preoperative exercise intervention on knee strength power and function post-surgery. [Subjects and Methods] Eighty male patients (27.8±5.7 age), scheduled for reconstruction surgery, were randomly assigned to two groups, the preoperative exercise group (n=40) and a no preoperative exercise group (n=40). The preoperative exercise group participated in a 4-week preoperative and 12-week post-operative programs, while the no preoperative exercise group participated only in the 12-week postoperative exercise program. Isokinetic measured of quadriceps strength were obtained at 4 weeks before and 3 months after surgery. [Results] The knee extensor strength deficits measured at 60°/s and 180°/s was significantly lower in the preoperative exercise group compared with the no preoperative exercise group. At 3 months after surgery, the extensor strength deficit was 28.5±9.0% at 60°/sec and 23.3±9.0% at 180°/sec in the preoperative exercise group, whereas the no preoperative exercise group showed extensor strength deficits of 36.5±10.7% and 27.9±12.6% at 60°/sec and 180°/sec, respectively. The preoperative exercise group demonstrated significant improvement the single-leg hop distance. [Conclusion] Four week preoperative exercise may produce many positive effects post reconstruction surgery, including faster recovery of knee extensor strength and function, as measured by single-leg hop ability.

“…A previous study indicated that both open and closed chain exercises improved the subjective and clinical outcomes of patients with patellofemoral pain, and that the closed chain exercise was a little more effective than the open chain exercise in functional results according to the tested parameters 20 ) . Although, open chain exercise was beneficial for the development of strength and endurance of the knee extensor mechanism following anterior cruciate ligament reconstruction, and could be used effectively in a rehabilitation program 21 ) , closed kinetic chain exercise seems to be more effective at improving dynamic balance ability than open kinetic chain exercise within a six-week training period 22 ) .…”

[Purpose] To compare the effects of open-chain exercise (OCE) and closed-chain exercise (CCE) for patients after medial patellofemoral ligament (MPFL) reconstruction. [Subjects and Methods] Forty patients after MPFL reconstruction were randomly divided into an OCE group and a CCE group. All the patients were evaluated at four different time points. [Results] The mean change of thigh circumference decrease in the CCE group was lower than that in the OCE group at both the 3rd and 6th month after surgery. The Lysholm score of the CCE group was higher than that of the OCE group at both the 3rd and 6th month. At the 3rd month after surgery, the visual analog scale score of the CCE group was lower than that of the OCE group. [Conclusion] CCE is better than OCE for both short and long term outcomes of patients after MPFL reconstruction.
