Abstract Background and Purpose. Nondistally fixated (ie, what is often referred to as “open kinetic chain” [OKC]) knee extensor resistance training appears to have lost favor for some forms of rehabilitation due partly to concerns that this exercise will irritate the extensor mechanism. In this randomized, single-blind clinical trial, nondistally fixated versus distally fixated (ie, often called “closed kinetic chain” [CKC]) leg extensor training were compared for their effects on knee pain. Subjects. Forty-three patients recovering from anterior cruciate ligament (ACL) reconstruction surgery (34 male, 9 female; mean age=29 years, SD=7.9, range=16–54). Methods. Knee pain was measured at 2 and 6 weeks after ACL reconstruction surgery using visual analog scales in a self-assessment questionnaire and during maximal isometric contractions of the knee extensors. Between test sessions, subjects trained 3 times per week using either OKC or CKC resistance of their knee and hip extensors as part of their physical therapy. Results. No differences in knee pain were found between the treatment groups. Discussion and Conclusion. Open kinetic chain and CKC leg extensor training in the early period after ACL reconstruction surgery do not differ in their immediate effects on anterior knee pain. Based on these findings, further studies are needed using different exercise dosages and patient groups.

Background. At a time of innovative medical technologies development, it is paramount that medical services be evaluated with regard to their effectiveness. Research in physical medicine and rehabilitation, as well as the specialty itself, is relatively young; however, the number of publications in the field has recently been increasing. The main aim of this article is to evaluate the effectiveness of cryotherapy, including local cryostimulation, after anterior cruciate ligament reconstruction. Material and methods. The present paper reviews scientific publications extracted from the Medline Embase, Cochra­ne Library, and PEDro databases according to a pre-designed search strategy. The review analysed publications where the authors indicated cryotherapy as an intervention in patients after ACL reconstruction and the study endpoints referred to analgesic or anti-oedema effects. Results. As a result of selection, 16 publications were chosen for the analysis, including 1 meta-analysis, 2 systematic reviews and 13 RCTs. Only the results of randomised studies are presented. Endpoints referring to analgesic effects were present in all of the studies in the analysis, while endpoints referring to anti-oedema effects were present in five studies. Statistically significant results constituted 62% of the results for analgesic effects and 60% for anti-oedema effects. Conclusions. 1. The currently limited evidence from randomised studies is not sufficient to draw final conclusions on the effectiveness of cryotherapy in patients after anterior cruciate ligament reconstruction. 2. It seems that cryotherapy can serve as an adjunct analgesic treatment in the early period after arthroscopic ACL reconstruction, while there is no notable improvement in patients after this procedure in reducing oedema.

Background: Anterior cruciate ligament (ACL) injuries are common. A goal of rehabilitation is to restore functional capacity. Currently, there are contrary opinions regarding the effectiveness of using either closed or open kinetic chain exercises (CKC, OKC) only, or a combination of both, following ACL injury, to obtain the most effective outcome. The debate also reflects the approach which places the least force on the ACL itself. Objective: To identify the evidence of effectiveness of closed versus open kinetic chain exercises, or a combination of both, in anterior cruciate ligament rehabilitation. Methods: A systematic review was undertaken of experimental studies published since 1990. Included studies were on humans with ACL injury. The ACL ligament could be healthy, ruptured, deficient or reconstructed. Studies on animals and cadavers were excluded. The methodological quality of included studies was appraised with the PEDro tool. Studies were graded according to hierarchy level, methodological quality, statistical significance, effect size, and clinical relevance. Recommendations were made on the strength of the body of evidence. The outcome measure of interest was force on the ACL during exercise. Results: 23 eligible studies were included. The majority of studies reflected lower level experimental designs with moderate methodological quality. Three studies showed a significant difference in ACL force comparing CKC and OKC exercises, 11 demonstrated trends towards significant differences in outcome and nine showed no significant differences. Conclusion: There is moderate evidence to recommend CKC exercises or a combination of CKC and OKC exercises, rather than OKC exercises alone, for ACL rehabilitation when considering forces on the ACL.

Rehabilitation following anterior cruciate ligament reconstruction with hamstring graft allows the patient to regain his functional capacities and to support him in the resumption of sports activities. Rehabilitation also aims to minimize the risk of recurrence, which is why it ensures that the patient's muscular capacities develop properly until they return to sport. Isokinetics helps strengthen and assess the strength of muscle groups in the thigh, but controversy exists as to its use by resistance to the open kinetic chain knee extension that would cause the transplant to distend. The objective of this study is to determine the influence of isokinetic muscle strengthening on the possible laxity of the anterior cruciate ligament and to be able to determine risk factors. The study relates to a population having benefited from anterior cruciate ligament reconstruction with hamstring graft from 3 to 6 months after surgery. Two groups are differentiated, one group exposed to isokinetism during rehabilitation, the other group, named unexposed, undergoes rehabilitation without the use of isokinetism. An anterior knee laxity test is performed 6 months postoperatively using the GNRB® machine for all subjects according to the same protocol. The test results were statistically analyzed to determine a relative risk of transplant distension for each group in the study. Comparison of the results of each group by univariate analysis did not reveal any significant result. Multivariate analysis showed interactions in the two strata of the study. It was argued that the use of isokinetics seems to have no effect on the risk of developing distension for the majority of subjects in the exposed group. A tendency towards transplant protection was perceived for each variable except the age under 25 years (RRa = 1.07). The use of isokinetics does not appear to be a cause of transplant distension in patients undergoing an anterior cruciate ligament reconstruction when this method is introduced 3 months postoperatively.


Background: There are various protocols for pain management after anterior cruciate ligament (ACL) reconstruction surgery. Objective: This study aimed to compare two blocking protocols, including femoral nerve block (FNB) and infrapatellar nerve block (IPNB) in terms of pain severity, patient satisfaction, and muscle force preservation. Materials and Methods: This single-blind clinical trial study investigated the patients who underwent elective knee arthroscopic ACL surgery randomly either by ultrasound-guided FNB or IPNB. Subsequently, the patients were evaluated 1, 3, 6, 12, and 24 h following NB for pain severity, patient satisfaction level, and muscle force. Results: The pain score (both at rest and in flexion) was significantly lower in the first three h after the intervention in the FNB group. Moreover, the mean score of the patients’ satisfaction in the first hours was significantly higher in the FNB group after the procedure. Additionally, the IPNB group obtained a significantly faster mean time required for the first dose of opioid request. The mean dose of used opioids over 24 h was significantly lower in the FNB group. There was a significant difference between the groups in terms of the muscle strength score within 24 h; moreover, the FNB group obtained a significantly greater delay in muscle recovery. Conclusion: The FNB is associated with greater pain relief and satisfaction in patients who underwent arthroscopic ACL reconstruction surgery, compared to the IFNB technique. However, a further delay in the recovery of quadriceps muscle force is evident in the FNB group.

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.
