Early Versus Delayed Mobilization Post-Operative Protocols for Primary Lateral Ankle Ligament Reconstruction: A Systematic Review and Meta-Analysis. Kans J Med 2021; 14:141-148.

Abstract
Introduction Lateral ankle instability represents a common orthopaedic diagnosis. Nonoperative treatment through focused physical therapy provides satisfactory results in most patients. However, some patients experience persistent chronic lateral ankle instability despite appropriate nonoperative treatment. These patients may require stabilization, which can include primary lateral ligament reconstruction with a graft to restore ankle stability. Optimal post-operative rehabilitation of lateral ankle ligament reconstruction remains unknown, as surgeons vary in how long they immobilize their patients post-operatively. The aim of this review was to provide insight into early mobilization (EM) versus delayed mobilization (DM) post-operative protocols in patients undergoing primary lateral ankle ligament reconstructions to determine if an optimal evidence-based post-operative rehabilitation protocol exists in the literature. Methods Following PRIMSA criteria, a systematic review/meta-analysis using the PubMed/Ovid Medline database was performed (10/11/1947 – 1/28/2020). Manuscripts that were duplicates, non-lateral ligament repair, biomechanical, and non-English language were excluded. Protocols were reviewed and divided into two categories: early mobilization (within three weeks of surgery) and delayed mobilization (after three weeks of surgery). Functional outcome scores (American Orthopedic Foot and Ankle Society Score (AOFAS), Karlsson scores), radiographic measurements (anterior drawer, talar tilt), and complications were evaluated using weighted mean differences (pre- and post-operative scores) and mixed-effect models. Results After our search, twelve out of 1,574 studies met the criteria for the final analysis, representing 399 patients undergoing lateral ankle reconstruction. Using weighted mean differences the DM group showed superior AOFAS functional scores compared to the EM group (28.0 (5.5) vs. 26.3 (0.0), respectively; p < 0.001), although sample size was small. Conversely, no significant differences were found for Karlsson functional score (p = 0.246). With regards to radiographic outcome, no significant differences were observed; anterior drawer was p = 0.244 and talar tilt was p = 0.937. A meta-analysis using mixed-effects models confirmed these results, although heterogeneity was high. Conclusions While there are some conflicting results, the findings indicated the timing of post-operative mobilization made no difference in functional outcomes or post-operative stability for patients undergoing lateral ankle ligament reconstruction. Because heterogeneity was high, future studies are needed to evaluate these protocols in less diverse patient groups and/or more consistent techniques for lateral ankle ligament reconstruction.

Abstract
Arthrofibrosis is a common, but often overlooked, condition that imparts significant morbidity following injuries and surgery to the foot and ankle. The most common etiologies are related to soft tissue trauma with subsequent fibrotic and contractile scar tissue formation within the ligaments and capsule of the ankle. This leads to pain, alterations in gait, and ankle dysfunction. Initial treatment often includes extensive physical therapy, however, if severe enough surgical options exist. Although the literature regarding ankle arthrofibrosis is scarce, this review article provides a greater understanding of the pathogenesis of arthrofibrosis and describes the current and future therapeutic options to treat fibrotic joints. Level of Evidence: Level V, expert opinion.

Abstract
BACKGROUND Range of motion restriction following immobilization is spontaneously recovered at least in part by remobilization. However, the mechanisms underlying how muscles change with range of motion recovery are poorly understood. This study aimed to reveal morphological and biomechanical changes in the knee flexor semitendinosus muscle that contribute to knee joint contracture following the relief of immobilization. METHODS To induce flexion contracture, we immobilized rat right knees by an external fixator at a flexed position for three weeks. After removal of the fixator, the joints were allowed to move freely (remobilization) for up to 14 days. We obtained muscle length and passive stiffness of the isolated semitendinosus muscles after measuring passive knee extension range of motion. FINDINGS Three weeks of immobilization induced range of motion reduction, as well as changes in morphological and biomechanical properties of the semitendinosus muscle, such as reduced muscle length and increment of passive stiffness leading to myogenic contracture. Joint immobilization-induced reduction of range of motion, representing flexion contracture, was partially reduced by 14 days of remobilization. Concomitantly, both muscle length and muscle stiffness returned to levels not significantly different from those in the contralateral side during this period. INTERPRETATION These results suggest that improvement of myogenic contracture during the early phase of remobilization occurs via both morphological and biomechanical adaptations.

Abstract
This study tested whether cell cycle inhibitor mitomycin C (MMC) prevents arthrogenic contracture progression during remobilization by inhibiting fibroblast proliferation and fibrosis in the joint capsule. Rat knees were immobilized in a flexed position to generate flexion contracture. After three weeks, the fixation device was removed and rat knees were allowed to freely move for one week. Immediately after and three days after fixator removal, rats received intra-articular injections of MMC or saline. The passive extension range of motion (ROM) was measured before and after myotomy of the knee flexors to distinguish myogenic and arthrogenic contractures. In addition, both cellularity and fibrosis in the posterior joint capsule were assessed histologically. Joint immobilization significantly decreased ROMs both before and after myotomy compared with untreated controls. In saline-injected knees, remobilization increased ROM before myotomy, but further decreased that after myotomy compared with that of knees immediately after three weeks of immobilization. Histological analysis revealed that hypercellularity, mainly due to fibroblast proliferation, and fibrosis characterized by increases in collagen density and joint capsule thickness occurred after remobilization in saline-injected knees. Conversely, MMC injections were able to prevent the remobilization-enhanced reduction of ROM after myotomy by inhibiting both hypercellularity and joint capsule fibrosis. Our results suggest that joint capsule fibrosis accompanied by fibroblast proliferation is a potential cause of arthrogenic contracture progression during remobilization, and that inhibiting fibroblast proliferation may constitute an effective remedy.

Abstract
Shortly after joint remobilization, inflammation is induced in the joint and aggravates joint contracture via subsequent fibrosis. However, the mechanisms involved in remobilization-induced inflammation are not yet fully understood. We hypothesized that joint immobilization followed by remobilization induces hypoxia/reoxygenation, initiating inflammatory reactions through nitric oxide (NO) production via NO synthase 2 (NOS2). This study aimed to investigate whether: 1) administration of the NOS inhibitor L-NG-nitroarginine methyl ester (l-NAME) can attenuate remobilization-induced joint inflammation; and 2) hypoxia/reoxygenation is induced by joint immobilization and followed by remobilization. Unilateral knee joints of rats were immobilized using external fixators for three weeks. After removal of the fixation device, knees were allowed to move freely for one day (remobilization) with or without l-NAME administration. Without l-NAME administration, inflammatory reactions including joint swelling and inflammatory cell infiltration, edema, and upregulation of inflammatory mediator genes in the joint capsule were detected following upregulation of the NOS2 gene after remobilization. These remobilization-induced inflammatory reactions were partially attenuated by administration of l-NAME. Therefore, NOS2/NO elevation has potential as a novel treatment for remobilization-induced joint inflammation. Gene expression of the hypoxia marker hypoxia inducible factor-1α was upregulated after one day of remobilization, rather than after immobilization. These results suggest that upregulation of NOS2 by remobilization might be not due to hypoxia/reoxygenation.

Abstract
This study investigated the effects of treadmill walking during remobilization on range of motion (ROM) and histopathology in rat knee joints, which were immobilized for 3 wk in a flexed position. After fixator removal, rats were divided into a no-intervention (RM) group and a group forced to walk on a treadmill daily at 12 m/min for 60 min (WALK group). Passive knee extension ROMs were measured before (m-ROM) and after (a-ROM) knee flexor myotomy on the first and last day of a 7-day remobilization period, with m-ROM mainly reflecting myogenic factors and a-ROM reflecting arthrogenic factors. Knee joints were histologically analyzed and gene expression of inflammatory or fibrosis-related mediators in the posterior joint capsule were examined. m-ROM and a-ROM restrictions were established after immobilization. m-ROM significantly increased following the remobilization period both in RM and WALK groups compared with that of immobilized (IM) group. Conversely, a-ROM decreased following the remobilization period in both RM and WALK groups compared with that of IM group. Importantly, a-ROM was smaller in the WALK group than the RM group. Remobilization without intervention induced inflammatory and fibrotic reactions in the posterior joint capsule after 1 and 7 days. Treadmill walking promoted these reactions and also increased the expression of fibrosis-related TGF-β1 and collagen type I and III genes. While free movement after immobilization improved myogenic contracture, arthrogenic contracture worsened. Treadmill walking further aggravated arthrogenic contracture through amplified inflammatory and fibrotic reactions. Thus active exercise immediately after immobilization may not improve immobilization-induced joint contracture. NEW & NOTEWORTHY In clinical practice, it is widely accepted that facilitation of joint movements is effective in improving immobilization-induced joint contracture. However, whether active exercises improve arthrogenic contracture is not known. In this study, we revealed that treadmill walking further promoted remobilization-induced progression of arthrogenic contracture. To our knowledge, this is the first study demonstrating no favorable effect of active exercise on immobilization-induced arthrogenic contracture.

Abstract
This study aimed to elucidate how rats recover from immobilization-induced knee joint contracture. Rats' right knees were immobilized by an external fixator at a flexion of 140° for 3 weeks. After removal of the fixator, the joints were allowed to move freely (remobilization) for 0, 1, 3, 7, or 14 days (n = 5 each). To distinguish myogenic and arthrogenic contractures, the passive extension range of motion was measured before and after myotomy of the knee flexors. Knee joints were histologically analyzed and the expression of genes encoding inflammatory or fibrosis-related mediators, interleukin-1β (1L-1β), fibrosis-related transforming growth factor-β1 (TGF-β1), and collagen type I (COL1A1) and III (COL3A1), were examined in the knee joint posterior capsules using real-time PCR. Both myogenic and arthrogenic contractures were established within 3 weeks of immobilization. During remobilization, the myogenic contracture decreased over time. In contrast, the arthrogenic contracture developed further during the remobilization period. On day 1 of remobilization, inflammatory changes characterized by edema, inflammatory cell infiltration, and upregulation of IL-1β gene started in the knee joint posterior capsule. In addition, collagen deposition accompanied by fibroblast proliferation, with upregulation of TGF-β1, COL1A1, and COL3A1 genes, appeared in the joint capsule between days 7 and 14. These results suggest the progression of arthrogenic contracture following remobilization, which is characterized by fibrosis development, is possibly triggered by inflammation in the joint capsule. It is therefore necessary to focus on developing new treatment strategies for immobilization-induced joint contracture. © 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Abstract
The toe flexor muscles maintain body balance during standing and provide push-off force during walking, running, and jumping. Additionally, they are important contributing structures to maintain normal foot function. Thus, weakness of these muscles may cause poor balance, inefficient locomotion and foot deformities. The quantification of metatarsophalangeal joint (MPJ) stiffness is valuable as it is considered as a confounding factor in toe flexor muscles function. MPJ and ankle joint stiffness measurement is still largely depended on manual skills as current devices do not have good control on alignment, angular joint speed and displacement during measurement. Therefore, this study introduces an innovative dynamometer and protocol procedures for MPJ and ankle Joint torque measurement with precise and reliable foot alignment, angular joint speed and displacement control. Within-day and between-day test-retest experiments on MPJ and ankle joint torque measurement were conducted on ten and nine healthy male subjects respectively. The mean peak torques of MPJ and ankle joint of between-day and within-day measurement were 1.50±0.38Nm/deg and 1.19±0.34Nm/deg. The corresponding torques of the ankle joint were 8.24±2.20Nm/deg and 7.90±3.18Nm/deg respectively. Intraclass-correlation coefficients (ICC) of averaged peak torque of both joints of between-day and within-day test-retest experiments were ranging from 0.91 to 0.96, indicating the innovative device is systematic and reliable for the measurements and can be used for multiple scientific and clinical purposes.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVES To compare early ankle movement versus ankle immobilization after surgery for ankle fracture on clinical and patient-reported outcomes. BACKGROUND A significant proportion of patients undergoing surgery for ankle fracture experience postoperative complications and delayed return to function. The risks and benefits of movement of the ankle in the first 6 weeks after surgery are not known, and clinical practice varies widely. METHODS We searched bibliographic databases and reference lists to identify eligible trials. Two independent reviewers conducted data extraction and risk-of-bias assessments. RESULTS Fourteen trials (705 participants) were included in the review, 11 of which were included in the meta-analysis. The quality of the trials was universally poor. The pooled effect of early ankle movement on function at 9 to 12 weeks after surgery compared to immobilization was inconclusive (standardized mean difference, 0.46; 95% confidence interval: -0.02, 0.93; P = .06; I(2) = 72%), and no differences were observed between groups at 1 year. The odds of venous thromboembolism were significantly lower with early ankle movement compared to immobilization (Peto odds ratio = 0.12; 95% confidence interval: 0.02, 0.71; P = .02; I(2) = 0%). Deep surgical site infection (Peto odds ratio = 7.08; 95% confidence interval: 1.39, 35.99; P = .02; I(2) = 0%), superficial surgical site infection, fixation failure, and reoperation to remove metalwork were more common after early ankle movement compared to immobilization. CONCLUSION The quality of evidence is poor. The effects of early movement after ankle surgery on short-term functional outcomes are unclear, but there is no observable difference in the longer term. There is a small reduction in risk of postoperative thromboembolism with early ankle movement. Current evidence suggests that deep and superficial surgical site infections, fixation failure, and the need to remove metalwork are more common after early ankle movement.

Abstract
BACKGROUND Rehabilitation after ankle fracture can begin soon after the fracture has been treated, either surgically or non-surgically, by the use of different types of immobilisation that allow early commencement of weight-bearing or exercise. Alternatively, rehabilitation, including the use of physical or manual therapies, may start following the period of immobilisation. This is an update of a Cochrane review first published in 2008. OBJECTIVES To assess the effects of rehabilitation interventions following conservative or surgical treatment of ankle fractures in adults. SEARCH METHODS We searched the Specialised Registers of the Cochrane Bone, Joint and Muscle Trauma Group and the Cochrane Rehabilitation and Related Therapies Field, CENTRAL via The Cochrane Library (2011 Issue 7), MEDLINE via PubMed, EMBASE, CINAHL, PEDro, AMED, SPORTDiscus and clinical trials registers up to July 2011. In addition, we searched reference lists of included studies and relevant systematic reviews. SELECTION CRITERIA Randomised and quasi-randomised controlled trials with adults undergoing any interventions for rehabilitation after ankle fracture were considered. The primary outcome was activity limitation. Secondary outcomes included quality of life, patient satisfaction, impairments and adverse events. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, assessed risk of bias and extracted data. Risk ratios and 95% confidence intervals (95% CIs) were calculated for dichotomous variables, and mean differences or standardised mean differences and 95% CIs were calculated for continuous variables. End of treatment and end of follow-up data were presented separately. For end of follow-up data, short term follow-up was defined as up to three months after randomisation, and long-term follow-up as greater than six months after randomisation. Meta-analysis was performed where appropriate. MAIN RESULTS Thirty-eight studies with a total of 1896 participants were included. Only one study was judged at low risk of bias. Eight studies were judged at high risk of selection bias because of lack of allocation concealment and over half the of the studies were at high risk of selective reporting bias.Three small studies investigated rehabilitation interventions during the immobilisation period after conservative orthopaedic management. There was limited evidence from two studies (106 participants in total) of short-term benefit of using an air-stirrup versus an orthosis or a walking cast. One study (12 participants) found 12 weeks of hypnosis did not reduce activity or improve other outcomes.Thirty studies investigated rehabilitation interventions during the immobilisation period after surgical fixation. In 10 studies, the use of a removable type of immobilisation combined with exercise was compared with cast immobilisation alone. Using a removable type of immobilisation to enable controlled exercise significantly reduced activity limitation in five of the eight studies reporting this outcome, reduced pain (number of participants with pain at the long term follow-up: 10/35 versus 25/34; risk ratio (RR) 0.39, 95% confidence interval (CI) 0.22 to 0.68; 2 studies) and improved ankle dorsiflexion range of motion. However, it also led to a higher rate of mainly minor adverse events (49/201 versus 20/197; RR 2.30, 95% CI 1.49 to 3.56; 7 studies).During the immobilisation period after surgical fixation, commencing weight-bearing made a small improvement in ankle dorsiflexion range of motion (mean difference in the difference in range of motion compared with the non-fractured side at the long term follow-up 6.17%, 95% CI 0.14 to 12.20; 2 studies). Evidence from one small but potentially biased study (60 participants) showed that neurostimulation, an electrotherapy modality, may be beneficial in the short-term. There was little and inconclusive evidence on what type of support or immobilisation was the best. One study found no immobilisation improved ankle dorsiflexion and plantarflexion range of motion compared with cast immobilisation, but another showed using a backslab improved ankle dorsiflexion range of motion compared with using a bandage.Five studies investigated different rehabilitation interventions following the immobilisation period after either conservative or surgical orthopaedic management. There was no evidence of effect for stretching or manual therapy in addition to exercise, or exercise compared with usual care. One small study (14 participants) at a high risk of bias found reduced ankle swelling after non-thermal compared with thermal pulsed shortwave diathermy. AUTHORS' CONCLUSIONS There is limited evidence supporting early commencement of weight-bearing and the use of a removable type of immobilisation to allow exercise during the immobilisation period after surgical fixation. Because of the potential increased risk of adverse events, the patient's ability to comply with the use of a removable type of immobilisation to enable controlled exercise is essential. There is little evidence for rehabilitation interventions during the immobilisation period after conservative orthopaedic management and no evidence for stretching, manual therapy or exercise compared to usual care following the immobilisation period. Small, single studies showed that some electrotherapy modalities may be beneficial. More clinical trials that are well-designed and adequately-powered are required to strengthen current evidence.

Abstract
BACKGROUND Ankle stiffness is a common complication after ankle fracture, reconstructive surgery or total ankle replacement, and the usual limitation is in dorsiflexion. There are few articles in the literature concerning this frequent problem, and furthermore they are not recent and tend to be controversial. The purpose of this anatomical study was to evaluate and quantify the effect of ankle collateral ligament release on dorsiflexion, specifically the amount of increase in ankle dorsiflexion following section of the two ligaments most often implicated in ankle stiffness: the deep posterior tibiotalar ligament (dPTTaL, or posterior deep deltoid) and the posterior talofibular ligament (PTaFL). METHODS We dissected 18 adult fresh cadaveric ankle joints, and with an electronic goniometer combined with an electronic dynamometer measured their mobility in dorsiflexion before and after transection of each ligament separately, and the two ligaments combined. RESULTS The results showed a significant difference between the two groups of ankles with section of the dPTTaL resulting in a greater increase in ankle dorsiflexion than section of the PTaFL (mean 7.45° vs. 3.5°, respectively; p<0.001). Combined section of both ligaments improved the gain in ankle dorsiflexion more than isolated section of each ligament, but was not statistically significant (p=0.88). CONCLUSION If after gastrocnemius recession or Achilles tendon lengthening persistent restriction remains in ankle dorsiflexion, the results of our study demonstrate that the next step should be release of the dPTTaL.

Abstract
Background Ankle fractures are common. Management of ankle fractures generally involves a period of immobilisation followed by rehabilitation to reduce pain, stiffness, weakness and swelling. The effects of a rehabilitation program are still unclear. However, it has been shown that important components of rehabilitation programs may not confer additional benefits over exercise alone. The primary aim of this trial is to determine the effectiveness and cost-effectiveness of an exercise-based rehabilitation program after ankle fracture, compared to advice alone. Methods/Design A pragmatic randomised trial will be conducted. Participants will be 342 adults with stiff, painful ankles after ankle fracture treated with immobilisation. They will be randomly allocated using a concealed randomisation procedure to either an Advice or Rehabilitation group. Participants in the Advice group will receive verbal and written advice about exercise at the time of removal of immobilisation. Participants in the Rehabilitation group will be provided with a 4-week rehabilitation program that is designed, monitored and progressed by a physiotherapist, in addition to verbal and written advice. Outcomes will be measured by a blinded assessor at 1, 3 and 6 months. The primary outcomes will be activity limitation and quality-adjusted life years. Discussion This pragmatic trial will determine if a rehabilitation program reduces activity limitation and improves quality of life, compared to advice alone, after immobilisation for ankle fracture.

Abstract
BACKGROUND Rehabilitation after ankle fracture can begin soon after the fracture has been treated by the use of different types of immobilisation which allow early commencement of weight-bearing or exercise. Alternatively, rehabilitation may start following the period of immobilisation, with physical or manual therapies. OBJECTIVES To compare the effectiveness of rehabilitation interventions following ankle fracture in adults. SEARCH STRATEGY We searched two Specialised Registers of The Cochrane Collaboration, electronic databases (including MEDLINE, EMBASE and CINAHL), reference lists of included studies and relevant systematic reviews, and clinical trials registers to September 2007. SELECTION CRITERIA Randomised and quasi-randomised controlled trials with adults undergoing any interventions for rehabilitation after ankle fracture were considered. The primary outcome was activity limitation. Secondary outcomes included impairments and adverse events. DATA COLLECTION AND ANALYSIS Two reviewers independently screened search results, assessed methodological quality, and extracted data. Relative risk and 95% confidence intervals (95% CI) were calculated for dichotomous variables, and weighted or standardised mean difference and 95% CI were calculated for continuous variables. A meta-analysis was performed where appropriate. MAIN RESULTS Thirty-one studies were included. Clinical and statistical heterogeneity prevented meta-analyses in most instances. After surgical fixation, commencing exercise in a removable brace or splint significantly improved activity limitation, pain and ankle range of motion, but also led to a higher rate of adverse events. Early commencement of weight-bearing during the immobilisation period improved ankle range of motion after surgical fixation. Where it was possible to avoid ankle range of motion after surgical fixation, the use of no immobilisation compared to cast immobilisation also improved ankle range of motion. After the immobilisation period, manual therapy was beneficial in increasing ankle range of motion. There was no evidence of effect for electrotherapy, hypnosis, or stretching. AUTHORS' CONCLUSIONS There is limited evidence supporting the use of a removable type of immobilisation and exercise during the immobilisation period, early commencement of weight-bearing during the immobilisation period, and no immobilisation after surgical fixation of ankle fracture. There is also limited evidence for manual therapy after the immobilisation period. Because of the potential increased risk, the patient's ability to comply with the use of a removable type of immobilisation and exercise is essential. More clinical trials that are well-designed and adequately-powered are required to strengthen current evidence.
