Abstract
Arthrofibrosis is a challenging complication associated with knee injuries in both children and adults. While much is known about managing arthrofibrosis in adults, it is necessary to understand its unique aspects and management strategies in the pediatric population. This paper provides an overview of arthrofibrosis in pediatric orthopedic surgery, focusing on its causes, implications, classifications, and management. This paper is a comprehensive review of the literature and existing research on arthrofibrosis in pediatric patients. Arthrofibrosis is characterized by excessive collagen production and adhesions, leading to restricted joint motion and pain. It is associated with an immune response and fibrosis within and around the joint. Arthrofibrosis can result from various knee injuries in pediatric patients, including tibial spine fractures, ACL and PCL injuries, and extra-articular procedures. Technical factors at the time of surgery play a role in the development of motion loss and should be addressed to minimize complications. Preventing arthrofibrosis through early physical therapy is recommended. Non-operative management, including dynamic splinting and serial casting, has shown some benefits. New pharmacologic approaches to lysis of adhesions have shown promise. Surgical interventions, consisting of arthroscopic lysis of adhesions (LOA) and manipulation under anesthesia (MUA), can significantly improve motion and functional outcomes. Arthrofibrosis poses unique challenges in pediatric patients, demanding a nuanced approach that includes prevention, early intervention with non-operative means, and improvements in surgical techniques. Modern pharmacological interventions offer promise for the future. Customized interventions and research focused on pediatric patients are critical for optimal outcomes.

Knee Surg Sports Traumatol Arthrosc 2024; 32:608-615. [PMID: 38341628 DOI: 10.1002/ksa.12073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 01/17/2024] [Accepted: 01/22/2024] [Indexed: 02/12/2024]
Abstract
PURPOSE The purpose of this study is to identify the rate and risk factors for a reoperation for arthrofibrosis following primary anterior cruciate ligament (ACL) reconstruction. METHODS Prospective data recorded in the New Zealand ACL Registry were cross-referenced with data from the Accident Compensation Corporation (ACC). Primary ACL reconstructions performed between April 2014 and May 2021 were analysed. The ACC database was used to identify patients who underwent a reoperation for a diagnosis of arthrofibrosis. Multivariable survival analysis was performed to compute adjusted hazard ratios (aHR) and 95% confidence intervals. RESULTS A total of 12,296 primary ACL reconstructions were analysed, of which 230 underwent a reoperation for arthrofibrosis (1.9%) at a mean follow-up of 3.6 years. A higher risk of arthrofibrosis was observed in females (aHR = 1.76, p = 0.001), patients with a history of previous knee surgery (aHR = 1.82, p = 0.04) and when a transtibial drilling technique was used (aHR = 1.53, p = 0.03). ACL reconstruction >6 months after injury had the lowest rate of arthrofibrosis (1.3%, aHR = 0.45, p = 0.01). There was no difference in risk between early surgery within 6 weeks versus delayed surgery between 6 weeks and 6 months after injury (2.9% versus 2.1%, aHR = 0.78, not significant). CONCLUSION Female sex, previous knee surgery and a transtibial drilling technique increased the risk of reoperation for arthrofibrosis. Early surgery within 6 weeks of injury was not associated with an increased risk when compared with surgery between 6 weeks and 6 months after injury. LEVEL OF EVIDENCE Level III.

Abstract
Introduction Knee arthrofibrosis is a disabling complication after anterior cruciate ligament reconstruction (ACLr). Different risk factors have been studied but are still controversial because of a diagnosis made only during reoperations for the treatment of the stiffness, which underestimates the occurrence rate. We aimed to confirm risk factors of arthrofibrosis after ACLr in case of clinically made diagnoses. Methods Ninety-two athletes with clinically diagnosed arthrofibrosis, complicating a primary ACLr, were compared to 482 athletes with ACLr without any complications. Usually considered risk factors were studied: age under 18, female, Body Mass Index (BMI ≥ 25), high sport level, time from ACL injury to ACLr < 1 month, Bone-Patella-Tendon-Bone surgical procedure (BPTB), meniscal repair, and intensive rehabilitation. Binary logistic regression was carried out to confirm or refute these risk factors. Results Female, time from ACL injury to ACLr < 1 month, BPTB procedure, meniscal repair, and BMI ≥ 25 were not confirmed as risk factors. Previous competitive sport level assessed by Tegner score was the only risk factor identified, OR: 3.56 (95%IC: 2.20-5.75; p = 0.0001). Age < 18, OR: 0.40 (95%IC: 0.19-0.84; p = 0.015) and inpatient rehabilitation program, OR: 0.28 (95%IC: 0.17-0.47; p = 0.0001), were protective factors. Discussion Competitive athletes are at risk of arthrofibrosis after ACLr and should benefit from protective inpatient rehabilitation program.

Localized Anterior Arthrofibrosis After Soft-Tissue Quadriceps Tendon Anterior Cruciate Ligament Reconstruction Is More Common in Patients Who Are Female, Undergo Meniscal Repair, and Have Grafts of Larger Diameter. Arthroscopy 2022; 39:1472-1479. [PMID: 36585324 DOI: 10.1016/j.arthro.2022.11.027] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Revised: 11/12/2022] [Accepted: 11/13/2022] [Indexed: 12/29/2022]
Abstract
PURPOSE To determine factors associated with localized anterior arthrofibrosis (cyclops lesion), such as graft size, warranting early reoperation for lysis of adhesions after anterior cruciate ligament reconstruction (ACLR) with all-soft tissue quadriceps tendon (ASTQT) autograft. METHODS All primary ASTQT autograft ACLRs within a single surgeon's prospectively collected registry with minimum 6-month follow-up were included. Patients who underwent multiligament knee reconstruction or cartilage restoration procedures were excluded. Localized anterior arthrofibrosis was defined as the requirement for a second procedure to achieve debridement and lysis of adhesions owing to the inability to regain terminal extension within 6 months of ACLR. The sex-specific incidence of arthrofibrosis was evaluated relative to age, weight, femoral and tibial tunnel sizes, meniscal repair, and meniscectomy by a binary logistic regression. RESULTS This study included 721 patients (46% female patients). There were 52 cases of localized anterior arthrofibrosis (7.2%). Female patients had a greater incidence of arthrofibrosis than male patients. Male patients with a femoral tunnel diameter of 9.25 mm or greater had an increased incidence of arthrofibrosis compared with those with a diameter of less than 9.25 mm, whereas a similar cutoff was not found to be statistically significant for female patients. Concomitant meniscal repair was associated with an increased risk of arthrofibrosis. CONCLUSIONS Female sex and concomitant meniscal repair were associated with an increased localized anterior arthrofibrosis incidence. Furthermore, ASTQT with a femoral tunnel diameter of 9.25 mm or greater in male patients was associated with an increased incidence of arthrofibrosis. LEVEL OF EVIDENCE: Level III, retrospective, comparative prognostic trial.

Abstract
Therapeutic approaches to treat joint contracture after anterior cruciate ligament (ACL) reconstruction have not been established. Arthrofibrosis accompanied by joint inflammation following ACL reconstruction is a major cause of arthrogenic contracture. In this study, we examined whether anti-inflammatory treatment using low-level laser therapy (LLLT) can prevent ACL reconstruction-induced arthrogenic contracture. Rats underwent ACL transection and reconstruction surgery in their right knees. Unoperated left knees were used as controls. After surgery, rats were reared with or without daily LLLT (wavelength: 830 nm; power output: 150 mW; power density: 5 W/cm2; for 120 s/day). We assessed the passive extension range of motion (ROM) after myotomy at one and two weeks post-surgery; the reduction in ROM represents the severity of arthrogenic contracture. ROM was markedly decreased by ACL reconstruction at both time points; however, LLLT partially attenuated the decrease in ROM. One week after ACL reconstruction, the gene expression of the proinflammatory cytokine interleukin-1beta in the joint capsule was significantly upregulated, and this upregulation was significantly attenuated by LLLT. Fibrotic changes in the joint capsule, including upregulation of collagen type I and III genes, shortening of the synovium, and thickening were caused by ACL reconstruction and seen at both time points. LLLT attenuated these fibrotic changes as well. Our results indicate that LLLT after ACL reconstruction could attenuate the formation of arthrogenic contracture through inhibition of inflammation and fibrosis in the joint capsule. Thus, LLLT may become a novel therapeutic approach for ACL reconstruction-induced joint contracture.

Significant risk of arthrolysis after simultaneous anterior cruciate ligament reconstruction and treatment of dislocated bucket-handle meniscal tear. Orthop Traumatol Surg Res 2022; 108:103252. [PMID: 35183759 DOI: 10.1016/j.otsr.2022.103252] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 11/15/2021] [Accepted: 12/07/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Postoperative stiffness is a feared complication after anterior cruciate ligament (ACL) reconstruction. In case of associated dislocated bucket-handle meniscal tear (BHMT), reduction is urgent, with ligament reconstruction in the same surgical step. HYPOTHESIS Treatment of associated dislocated BHMT in ACL reconstruction incurs increased risk of arthrolysis for stiffness in flexion and/or extension. MATERIAL AND METHODS A retrospective exposure/non-exposure study included 208 patients undergoing ACL reconstruction between January 2009 and December 2018. Those showing dislocated medial or lateral BHMT at surgery (group A) were compared versus those free of meniscal lesions (group B). The main objective was to assess the risk of surgical revision for arthrolysis within 12 months. Group A included 69 patients: 40 male (58%), 29 female (42%); mean age, 29.0±11.2 years. Group B included 139 patients: 68 male (49%), 71 female (51%); mean age, 30.0±10.4 years. Patients were classified according to age of ACL tear, as acute (<6 weeks), subacute (6 weeks to 6 months), or chronic (>6 months). RESULTS Risk of revision surgery for arthrolysis was greater in Group A than in Group B, with 7 (10.1%) and 4 (2.9%) cases respectively (p=0.044), with 12-month arthrolysis-free survival of 89.7% (95% CI, 82.7-97.2) and 97.1% (95% CI, 94.3-99.9) respectively (p=0.023). Stiffness in flexion and extension was more frequent in Group A at 6 weeks and at 6 months (p>0.05). Risk of arthrolysis did not significantly differ according to accident-to-surgery time in the overall series (p=0.421) or specifically in Group A (p=0.887). The BHMT was sutured in 39 cases (56.5%), including 3 failures (7.7%) at 12 months' follow-up. Arthrolysis was required in 6 patients treated by meniscal suture (15.4%) and just 1 patient treated by meniscectomy (3.3%) (p=0.128). CONCLUSION The present study confirmed increased risk of surgical revision for arthrolysis after ACL reconstruction in case of dislocated BHMT treated in the same surgical step. Age of ACL tear and type of BHMT treatment (suture or meniscectomy) showed no impact on postoperative stiffness. LEVEL OF EVIDENCE IV, retrospective exposure/non-exposure cohort study.

Abstract
Knee arthrofibrosis is a common complication of knee surgery, caused by excessive scar tissue, which results in functional disability. However, no curative treatment has been established. E8002 is an anti-adhesion material that contains L-ascorbic acid, an antioxidant. We aimed to evaluate the efficacy of E8002 for the prevention of knee arthrofibrosis in a rat model, comprising injury to the surface of the femur and quadriceps muscle 1 cm proximal to the patella. Sixteen male, 8-week-old Sprague Dawley rats were studied: in the Adhesion group, haemorrhagic injury was induced to the quadriceps and bone, and in the E8002 group, an adhesion-preventing film was implanted between the quadriceps and femur after injury. Six weeks following injury, the restriction of knee flexion owing to fibrotic scarring had not worsened in the E8002 group but had worsened in the Adhesion group. The area of fibrotic scarring was smaller in the E8002 group than in the Adhesion group (p < 0.05). In addition, the numbers of fibroblasts (p < 0.05) and myofibroblasts (p < 0.01) in the fibrotic scar were lower in the E8002 group. Thus, E8002 reduces myofibroblast proliferation and fibrotic scar formation and improves the range of motion of the joint in a model of knee injury.

Abstract
Knee joint contracture is often induced by anterior cruciate ligament reconstruction (ACLR). However, the temporal and spatial arthrofibrotic changes following inflammatory events, which occur in parallel with the formation of joint contractures after ACLR, are unknown. This study aimed to reveal: (a) time-dependent changes in myogenic and arthrogenic contractures; and (b) the process of arthrofibrosis development after ACLR. ACLR was performed on knees of rats unilaterally. Passive ranges of motions (ROMs) before and after myotomy, as well as inflammatory and fibrotic reactions, were examined before and after the surgery at various periods up to 56 days. Both ROMs before and after myotomy exhibited their lowest value on day 7 and increased thereafter in a time-dependent manner; nevertheless, significant restrictions remained by day 56. Myotomy partially increased ROMs at all time points, indicating contribution of the myogenic component to ACLR-induced contracture. Inflammatory and fibrotic reactions peaked on day 7. Arthrofibrosis, characterized by the thickening of the joint capsule and the shortening of the synovial length, was established by day 7 and was not completely resolved by day 56. Our results indicate that: (a) both myogenic and arthrogenic contractures generated through ACLR develop maximally by day 7 after surgery and subside thereafter, but persist at least until day 56; and (b) arthrofibrosis is established by day 7 after surgery and is not completely resolved by day 56. These findings suggest that treatment and intervention for preventing joint contracture after ACLR should be performed within the first 7 days after surgery.

Abstract
Background Joint stiffness is a common complication after anterior cruciate ligament (ACL) reconstruction, which seriously affects the efficacy of the operation and patient satisfaction. After ACL reconstruction, the identification of joint stiffness’ risk factors can help its prevention. This meta-analysis was conducted to evaluate joint stiffness’ risk factors and incidence after ACL reconstruction and provide guidance on its prevention. Methods PubMed, Embase, and Cochrane Library were searched to obtain relevant studies. The odds ratios (ORs) with 95% confidence intervals (CIs) for all potential risk factors were analyzed using fixed or random-effects meta-analysis in RevMan 5.2. Results In total, there were 37 studies and 113,740 patients that were included in this study. After ACL reconstruction, joint stiffness’ incidence negatively correlated with the studies publication time (R = −0.62, P = 0.0094). After ACL reconstruction, the joint stiffness overall pooled incidence was 3% (95% CI, 3-4%). Gender (OR, 0.51; 95% CI, 0.38-0.68; P < 0.00001) was identified as a risk factor. Potential risk factors, such as trauma to surgery time interval, graft type, and concomitant surgery with meniscus injury, have no significant correlation with joint stiffness after ACL reconstruction. Conclusion This study indicated that joint stiffness’ incidence after ACL reconstruction is 3% and that gender is a risk factor for joint stiffness after ACL reconstruction.

Reduction of adhesion formation after knee surgery in a rat model by botulinum toxin A. Biosci Rep 2017; 37:BSR20160460. [PMID: 28115594 PMCID: PMC5398255 DOI: 10.1042/bsr20160460] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2016] [Revised: 01/20/2017] [Accepted: 01/23/2017] [Indexed: 11/17/2022] Open
Abstract
Adhesion of the knee is a major concern after knee surgery, the treatment of which is difficult. Botulinum toxin A (BTX-A) injection is demonstrated as efficient in treating knee adhesion after surgery. However, the treatment outcomes and the mechanism of action are not yet determined. The aim of the present study was to examine the effects and molecular mechanism of a BTX-A treatment in preventing adhesion of the knee. Twenty-four Wistar rats were randomly divided into a BTX-A treatment group and a control group. BTX-A or saline was injected into the cavity of the knee in the BTX-A treatment or control group respectively. Gross and histopathological examinations of interleukin 1 (IL-1) and fibroblast growth factor (FGF) levels, as well as fibroblast cell numbers, were assessed in the knee intra-articular adhesions in each group 6 weeks after recovery from the surgery. Macroscopic observations showed a significant reduction in adhesion severity in the BTX-A treatment group compared with the control group. In addition, the levels of IL-1 and FGF were lower and the number of fibroblasts was smaller in the BTX-A treatment group compared with those in the control group. BTX-A prevented intra-articular adhesion of knee in the rats, which might be associated with reduced expressions of IL-1 and FGF.

Abstract
BACKGROUND Postoperative extension deficits following anterior cruciate ligament (ACL) reconstruction can cause major limitation during daily life. The purpose of this study was to evaluate the efficiency of an all-arthroscopic approach and posterior capsule release for the treatment of persistent knee extension deficits following ACL reconstruction. METHODS Between 2009 and 2013 a total of 10 patients with knee flexion contractures after ACL reconstruction were assessed following an all-arthroscopic approach and posterior capsulotomy. The clinical outcomes were reviewed using the range of motion (ROM), Tegner Activity Level, Lysholm score and visual analogue pain scale (VAS). RESULTS Four women and six men with a median age of 34years (range: 17 to 49years) were included in the study. The median follow-up period was 25months (range: 14 to 69months). The median preoperative extension deficit was 15° (range: 10 to 20°) compared to the normal contralateral knee. Postoperatively at final follow-up the median extension deficit was one degree (range: 0 to five degrees) (P<0.01). The median preoperative Lysholm score improved from 52 (range: 32 to 67) to 92 (range: 84 to 100) postoperatively (P<0.01), while the median Tegner Activity Level improved from three (range: two to six) to six (range: three to seven) respectively (P<0.02). The median VAS status for pain decreased from five (range: one to 10) to one (range: 0 to three) (P<0.01). No complications were observed. CONCLUSIONS Arthroscopic posterior capsulotomy is a safe and effective additional procedure in the treatment of persistent knee extension deficits following ACL reconstruction with excellent results regarding ROM and subjective outcomes. LEVEL OF EVIDENCE Level IV.

Abstract
OBJECTIVES To assess the impact of cyclops lesions with MRI in patients treated for anterior cruciate ligament (ACL) tears on clinical outcome. METHODS In 113 patients (age 29.8 ± 10.5y; 55 females; BMI 24.8 ± 3.7 kg/m2) with complete ACL tear, 3 T-MRI scans were obtained before, 6-months, 1-year (n = 75) and 2-years (n = 33) after ACL reconstruction. Presence and volume of cyclops lesions were assessed. Clinical outcomes were measured using the Knee injury and Osteoarthritis Outcome Score (KOOS) and differences between time points (∆KOOS) were calculated. Changes of KOOS subscales were compared between patients with and without cyclops lesion. KOOS was also correlated with lesion volume. RESULTS Cyclops lesions were found in 25% (28/113), 27% (20/75) and 33% (11/33) of patients after 6-months, 1- and 2-years, respectively. The lesion volume did not change significantly (P > 0.05) between time points, measuring 0.65 ± 0.59, 0.81 ± 0.70 and 0.72.9 ± 0.96 cm3, respectively. Clinical outcomes based on KOOS subscales were not significantly different in patients with cyclops lesions compared to those without cyclops lesions (each comparison P > 0.05), and no significant associations of clinical outcomes with lesion volume were found (P > 0.05). CONCLUSIONS Neither presence nor size of cyclops lesions within the first 2-years after ACL surgery were associated with inferior clinical outcome. KEY POINTS • Cyclops lesions had a prevalence of 25% in patients after ACL reconstruction. • Subjects with cyclops lesions did not have an inferior clinical outcome. • Cyclops lesions developed within the first 6 months after surgery. • The size of cyclops lesions did not significantly change over a period of 2 years.

Abstract
BACKGROUND Post-traumatic stiffness after open reduction and internal fixation of fractures about the knee can have dramatic effects on function. Traditionally, open quadricepsplasty has been the treatment of choice, but is associated with significant morbidity. PURPOSE The purpose of this study is to examine the immediate and sustainable range of motion (ROM) changes after surgical arthroscopic lysis of knee adhesions (SALKA) for post-traumatic knee stiffness after open reduction internal fixation (ORIF). METHODS We retrospectively reviewed a consecutive series of patients at a single institution who underwent SALKA for knee stiffness after intra-articular fractures about the knee treated with ORIF from 2009 to 2015. Pre-operative and immediate post-operative total ROM was assessed while patients were sedated during the SALKA procedure. Total ROM was assessed in the office pre-operatively and compared to the latest post-operative follow-up visit. Immediate post-operative ROM was also compared to the latest post-operative follow-up visit. Two-tailed paired Student's t test was calculated for analysis. RESULTS Of the 14 patients included in the study, 10 (71 %) had tibial plateau ORIF, 3 (21 %) had patella ORIF, and 1 (8 %) had intra-articular distal femur ORIF. The mean time between ORIF and SALKA was 244 days. The mean follow-up time after SALKA was 135 days. Under sedation during SALKA, the mean total ROM increased from 72° to 127° immediately post-operatively (p < 0.01). The mean pre-operative in-office total ROM was 73° and increased to 104° at the latest follow-up visit (p < 0.01). The mean immediate post-operative ROM was 127° and decreased to 104° at the latest follow-up visit (p = 0.01). CONCLUSION Lysis of adhesions utilizing SALKA after ORIF about the knee improves knee ROM immediately post-operatively and in the short-term follow-up. However, there is a decrease in the gains in the range of motion over time. Patients should be counseled as such. Lysis of adhesions utilizing arthroscopic techniques may provide a favorable alternative to open quadricepsplasty.

Abstract
Knee pain is one of the most frequent complaints evaluated by orthopedic surgeons. It encompasses a broad range of pathology and can present in a variety of ways. Most of this pain can be attributed to essential structures of the knee, including the menisci, cruciate or collateral ligaments, and articular cartilage. However, there are underrecognized structures in and around the knee that can frequently be a cause of knee pathology and pain. Knee pain stemming from these structures may be missed or incorrectly diagnosed, and these patients often present for second and third opinions because of failure to diagnose and treat the underlying pathology. The synovial plica, suprapatellar pouch, lateral retinaculum, infrapatellar fat pad, and infrapatellar branch of the saphenous nerve are less common but still significant causes of knee pain. Although initial treatment involves various nonoperative modalities, operative treatment is often warranted. Operative and nonoperative management of these soft tissue structures may occur in isolation or with concomitant procedures, including knee ligament reconstruction, total knee arthroplasty, tibial tuberosity osteotomy, or lysis of adhesions. With proper recognition of the role of these structures in knee pain, the orthopedic surgeon can offer a valuable primary or adjunctive treatment option for patients with knee pain, especially those without localizing signs of meniscal, ligamentous, or cartilage damage.

Abstract
Synovial fibrosis is often found in OA, contributing heavily to joint pain and joint stiffness, the main symptoms of OA. At this moment the underlying mechanism of OA-related synovial fibrosis is not known and there is no cure available. In this review we discuss factors that have been reported to be involved in synovial fibrosis. The aim of the study was to gain insight into how these factors contribute to the fibrotic process and to determine the best targets for therapy in synovial fibrosis. In this regard, the following factors are discussed: TGF-β, connective tissue growth factor, procollagen-lysine, 2-oxoglutarate 5-dioxygenase 2, tissue inhibitor of metalloproteinase 1, A disintegrin and metalloproteinase domain 12, urotensin-II, prostaglandin F2α and hyaluronan.

Abstract
The aim of this study was to report the incidence of arthrofibrosis of the knee and identify risk factors for its development following a fracture of the tibial plateau. We carried out a retrospective review of 186 patients (114 male, 72 female) with a fracture of the tibial plateau who underwent open reduction and internal fixation. Their mean age was 46.4 years (19 to 83) and the mean follow-up was16.0 months (6 to 80). A total of 27 patients (14.5%) developed arthrofibrosis requiring a further intervention. Using multivariate regression analysis, the use of a provisional external fixator (odds ratio (OR) 4.63, 95% confidence interval (CI) 1.26 to 17.7, p = 0.021) was significantly associated with the development of arthrofibrosis. Similarly, the use of a continuous passive movement (CPM) machine was associated with significantly less development of arthrofibrosis (OR = 0.32, 95% CI 0.11 to 0.83, p = 0.024). The effect of time in an external fixator was found to be significant, with each extra day of external fixation increasing the odds of requiring manipulation under anaesthesia (MUA) or quadricepsplasty by 10% (OR = 1.10, p = 0.030). High-energy fracture, surgical approach, infection and use of tobacco were not associated with the development of arthrofibrosis. Patients with a successful MUA had significantly less time to MUA (mean 2.9 months; sd 1.25) than those with an unsuccessful MUA (mean 4.86 months; sd 2.61, p = 0.014). For those with limited movement, therefore, performing an MUA within three months of the injury may result in a better range of movement. Based our results, CPM following operative fixation for a fracture of the tibial plateau may reduce the risk of the development of arthrofibrosis, particularly in patients who also undergo prolonged provisional external fixation.

Abstract
Arthrofibrosis is a major complication of tibial spine fracture treatment in children, potentially resulting in knee pain, quadriceps weakness, altered gait, decreased function, inability to return to sports, and long-term osteoarthritis. Thus, prevention rather than treatment of arthrofibrosis is desirable. The purpose of this study was to evaluate an aggressive postoperative rehabilitation and early intervention approach to prevent permanent arthrofibrosis after tibial spine fracture treatment and to compare epiphyseal and transphyseal screws for fixation. A consecutive series of 24 patients younger than age 18 with displaced type II and III tibial spine fractures who underwent arthroscopic reduction and screw fixation between 2006 and 2011 were retrospectively reviewed. Final range of motion was compared between patients with epiphyseal (n=12) and transphyseal (n=9) screws. One-third (4 of 12) of patients with epiphyseal screws underwent arthroscopic debridement and screw removal approximately 3 months postoperatively; 3 patients lacked 5° to 15° of extension, 1 experienced pain with extension, and 1 had radiographic evidence of screw pullout, loss of reduction, and resultant malunion. In the transphyseal screw group, 3 patients had 10° loss of extension, and all corrected after arthroscopic debridement and screw removal. The two groups did not significantly differ in time to hardware removal or return to sports or final range of motion. No growth disturbances were identified in patients after transphyseal screw removal. An aggressive approach of postoperative rehabilitation and early intervention after arthroscopic reduction and screw fixation of tibial spine fractures in children was successful in preventing permanent arthrofibrosis.

Abstract
Purpose To assess the results of arthroscopic adhesiolysis for arthrofibrosis of the knee and to investigate possible prognostic factors. Materials and Methods Among the patients who developed arthrofibrosis after knee joint surgery, 68 patients who underwent arthroscopic adhesiolysis and were available for at least one-year follow-up were evaluated with regard to the Lysholm knee score, International Knee Documentation Committee (IKDC) subjective knee score, patient satisfaction, and range of motion (ROM) of the knee. The influence of possible prognostic factors including the cause of arthrofibrosis, duration of disease, and age of the patient on the postoperative ROM was analyzed. Results Sixty-one patients (89.7%) obtained an average increase of 48.6° in ROM; however, the remaining seven patients (10.3%) did not show any increase at the final follow-up. The Lysholm knee score and IKDC subjective knee score increased significantly at the final follow-up. Patient satisfaction was high or very high in 89.7% of the patients at the final follow-up. There was no association between the cause of arthrofibrosis and the increase in postoperative ROM. The duration of disease was significantly related to the postoperative recovery of ROM. Age had no significant influence on the postoperative recovery of ROM. Conclusions We believe that arthroscopic adhesiolysis is effective for the treatment of intraarticular arthrofibrosis. In particular, the duration of the disease had significant influence on the postoperative outcome.

Abstract
BACKGROUND Arthrofibrosis is a postoperative complication of intra-articular knee surgery that can be difficult to treat. Evidence suggests that maximizing knee range of motion may improve outcomes in patients with arthrofibrosis who undergo arthroscopic debridement. HYPOTHESIS Patients who achieve greater knee range of motion will have better subjective scores. STUDY DESIGN Retrospective case series analysis. METHODS A review of records was performed for 33 patients with arthrofibrosis who underwent knee arthroscopy and scar resection coupled with perioperative rehabilitation to maximize knee range of motion. Patient demographics and preoperative and postoperative range of motion measurements were extracted from the records. The International Knee Documentation Committee (IKDC) Subjective Knee Form was administered to assess pain, activity, and knee function. Patients performed a preoperative and postoperative rehabilitation program utilizing a knee extension device to maximize knee extension. RESULTS According to the IKDC range of motion criteria, 27 of 33 patients achieved normal knee extension, and 14 of 33 achieved normal knee flexion at a mean of 8.6 months after surgery. Patients with normal knee motion had a mean IKDC Subjective Knee Form score of 72.6 ± 13.6, which was significantly higher than patients who did not achieve normal motion (P = .04). Overall, mean IKDC Subjective Knee Form scores improved from 45.3 ± 16.7 preoperatively to 67.1 ± 18.0 postoperatively (P < .01) at a mean of 14.7 months after surgery. CONCLUSIONS Perioperative rehabilitation that emphasizes restoration of normal knee range of motion appears to improve outcomes in patients with arthrofibrosis who undergo arthroscopic scar resection. In support of our hypothesis, patients who achieved greater knee range of motion had better subjective knee scores.

Abstract
The infrapatellar fat pad (IFP), also known as Hoffa's fat pad, is an intracapsular, extrasynovial structure that fills the anterior knee compartment, and is richly vascularized and innervated. Its degree of innervation, the proportion of substance-P-containing fibres and close relationship to its posterior synovial lining implicates IFP pathologies as a source of infrapatellar knee pain. Though the precise function of the IFP is unknown, studies have shown that it may play a role in the biomechanics of the knee or act as a store for reparative cells after injury. Inflammation and fibrosis within the IFP, caused by trauma and/or surgery can lead to a variety of arthrofibrotic lesions including Hoffa's disease, anterior interval scarring and infrapatellar contracture syndrome. Lesions or mass-like abnormalities rarely occur within the IFP, but their classification can be narrowed down by radiographical appearance. Clinically, patients with IFP pathology present with burning or aching infrapatellar anterior knee pain that can often be reproduced on physical exam with manoeuvres designed to produce impingement. Sagittal MRI is the most common imaging technique used to assess IFP pathology including fibrosis, inflammation, oedema, and mass-like lesions. IFP pathology is often successfully managed with physical therapy. Passive taping is used to unload or shorten an inflamed IFP, and closed chain quadriceps exercises can improve lower limb control and patellar congruence. Training of the gluteus medius and stretching the anterior hip may help to decrease internal rotation of the hip and valgus force at the knee. Gait training and avoiding hyperextension can also be used for long-term management. Injections within the IFP of local anaesthetic plus corticosteroids and IFP ablation with ultrasound guided alcohol injections have been successfully explored as treatments for IFP pain. IFP pathology refractory to physical therapy can be approached through a variety of operative treatments. Arthroscopic partial resection for IFP impingement and Hoffa's disease has showed favourable results; however, total excision of the IFP performed concomitantly with total knee arthroplasty (TKA) resulted in worse results when compared with TKA alone. Arthroscopic debridement of IFP fibrosis has been successfully used to treat extension block following anterior cruciate ligament reconstruction, and arthroscopic anterior interval release has been an effective treatment for pain associated with anterior interval scarring. Arthroscopic resection of infrapatellar plicae and denervation of the inferior pole of the patella have also been shown to be effective treatments for refractory infrapatellar pain.

Abstract
INTRODUCTION Arthrofibrosis is a known complication after anterior cruciate ligament (ACL) reconstruction. ACL reconstruction is being performed with increased frequency in the pediatric population. The purpose of this study was to determine the prevalence of arthrofibrosis in children and adolescents and to identify risk factors for arthrofibrosis. METHODS The study design was a retrospective case series. Medical records for 1016 consecutive ACL reconstructions in patients aged 7 to 18 years old between 1995 to 2008 at a major tertiary care children's hospital were reviewed to identify cases of postoperative arthrofibrosis. Arthrofibrosis was defined as a loss of 5 degrees or more extension compared with the contralateral knee that required a follow-up procedure or a loss of 15 degrees or more flexion compared with the contralateral knee that required a follow-up procedure. Patient data were recorded and analyzed using bivariate models to identify predictors for arthrofibrosis. Further, we reviewed the clinical course of patients with treated arthrofibrosis to assess functional outcomes of this complication. RESULTS Nine hundred two patients with 933 knees met the inclusion criteria for this study, of which 60% were female. The mean age at the time of surgery was 15 years (range, 7 to 18 y), and the average follow-up from original ACL reconstruction was 6.3 years (range, 1.6 to 14.2 y). The overall prevalence of arthrofibrosis in our cohort was 8.3%, with 77 of the 933 knees had at least 1 procedure to treat arthrofibrosis after ACL reconstruction. Risk factors for arthrofibrosis were female sex (11.1% females, P = 0.0001), patients aged 16 to 18 years [11.6%; odds ratio (OR) 3.51; P = 0 .007], patellar tendon autograft (OR, 1.7; P = 0.026), and concomitant meniscal repair (OR, 2.08; P = 0.007). Prior knee surgery and ACL reconstruction within 1 month of injury were not significantly associated with arthrofibrosis after ACL reconstruction. Fifty-three patients had a minimum of 6 months clinical follow-up after the procedure for arthrofibrosis. Of these, 46 patients (86.8%) had full range of motion at follow-up. Thirty-two patients (60.4%) were asymptomatic at final follow-up. Eleven patients (20.8%) complained of some persistent pain. CONCLUSIONS The rate of arthrofibrosis after ACL reconstruction in children and adolescents is 8.3%. Risk factors for arthrofibrosis are female sex, older adolescents, concurrent meniscal repair, and reconstruction with patellar tendon autograft. Surgical treatment for arthrofibrosis after ACL reconstruction in pediatric patients can satisfactorily regain motion in the reconstructed knee; however functional outcome may be compromised. LEVEL OF EVIDENCE Level 4.

Abstract
PURPOSE Clinical outcome following surgical treatment and intensive physiotherapy was evaluated in patients with arthrofibrosis as a complication to varying knee-ligament reconstructions. METHODS From 2003 to 2007, 31 patients underwent surgery for arthrofibrosis as a postoperative complication following knee-ligament reconstruction. Treatment for reduced range of motion consisted of forced manipulation or arthroscopic arthrolysis followed by intensive physiotherapy. Twenty-seven patients (12 men and 15 women; median age 35(12-70) years) were followed up. Objective examination, Pain, KOOS and Tegner scores were used to evaluate the clinical outcome at follow-up. RESULTS Fourteen patients were treated with forced manipulation alone, and the remaining thirteen were treated with forced manipulation and arthroscopic arthrolysis. The patients' median follow-up was 51 months (19-73 months). Median interval between primary surgery and surgical release was 4 (1-32) months. Median range of motion (ROM) improved from -0°(0 to 20) to 0°(+2-9) in extension deficit and from 90°(40-145) to 130°(90-155) in flexion. Mean KOOS score were symptoms 63, pain 72, ADL 77, sport 42, QOL 45. Median Tegner score was 4 (2-9). CONCLUSION Surgical arthrolysis combined with intensive physiotherapy improved range of motion to nearly normal values. Subjective outcome scores revealed relatively poor outcome levels compared to uncomplicated knee-ligament reconstruction. Predictors of poor outcome were global arthrofibrosis and greater than 6-month time interval from primary reconstruction and surgical release. LEVEL OF EVIDENCE Retrospective clinical case series, Level IV.

Mechanics of the anterior interval of the knee using open dynamic MRI. Clin Biomech (Bristol, Avon) 2010; 25:433-7.

Abstract
BACKGROUND The anterior interval of the knee has been defined as the space between the infrapatellar fat pad and patellar tendon anteriorly, and the anterior border of the tibia and the transverse meniscal ligament posteriorly. Investigation of the normal kinematics of this region is necessary as we begin to appreciate the significant impact that pathologic processes of the anterior interval have on the knee. METHODS Non-weight bearing and weight bearing dynamic MRIs of 20 healthy knees were evaluated at 30 degrees intervals from 0 degrees to 120 degrees flexion. The angle subtended by the patellar tendon and the anterior tibia was measured at each interval of flexion by three independent observers. The amount of angular change over each interval of flexion was also evaluated and the differences between the relative weight bearing conditions were statistically evaluated. FINDINGS The angle formed by the anterior tibia and the patellar tendon decreases with knee flexion (45.2 degrees (SD 10.1 degrees ) at full extension vs. 1.2 degrees (SD 2.1 degrees ) at full flexion). The average patellar tendon-tibial angle excursion was significantly reduced with full-weight bearing, 43.1 degrees (SD 11.2 degrees ) from 0 degrees to 120 degrees of flexion, compared to non-weight bearing, 30.9 degrees (SD 6.1 degrees ) over the same range of motion (P<0.001). Full-weight bearing decreased the angle excursion by 28% compared to non-weight bearing. INTERPRETATION The observed changes in the anterior interval are influenced by multiple factors including load, knee architecture, tendon elasticity and tibio-femoral and patello-femoral kinematics. The impact of load on the mechanics of the anterior interval is most pronounced between 0 degrees and 30 degrees of flexion.

Abstract
Twenty-two total knee replacements (TKR's) were treated for stiffness with arthroscopy and arthrolysis. The median follow-up was 38 months. No patients were lost to follow up. Extensive scarring was found and debrided in all of the knees. The mean Oxford Knee Score improved from 42.6 (+/-7.5) to 36.3 (+/-8.5) (P < 0.05) with TKR and from 36.3 (+/-8.5) to 29.3 (+/-9.0) (P < 0.05) with arthroscopic arthrolysis. The mean arc of motion improved from 8-69 degrees post-TKR to 3-105 degrees on table, but declined slightly to 4-93 degrees (P < 0.05) at most recent review. Arthroscopic arthrolysis compares well with other methods of treatment for stiffness with regard to improvements in range of motion and functional knee scores.

Abstract
BACKGROUND Patients with a history of knee trauma or previous surgery may exhibit pain in the infrapatellar region that is refractory to conservative care. This may be due to subtle scarring of the anterior interval. HYPOTHESIS Arthroscopic release of a scarred anterior interval will lead to improvement in anterior knee pain. STUDY DESIGN Case series; Level of evidence, 4. METHODS Twenty-five consecutive patients with isolated scarring of the anterior interval, confirmed with both magnetic resonance imaging (MRI) and arthroscopic examination, were included. All 25 patients had refractory anterior knee pain that was unimproved after a minimum of 6 months of physical therapy and nonsteroidal anti-inflammatory medications and pain during knee extension. All patients had a minimum of 2 previous surgical procedures, and 11 (44%) of the patients had a previous anterior cruciate ligament (ACL) reconstruction. All 25 (100%) patients had an apparent decrease in the cranial excursion of the patella and had a positive Hoffa test result. Fourteen (56%) patients had a preoperative flexion contracture of at least 5 degrees . All patients underwent an isolated arthroscopic anterior interval release. RESULTS All patients were evaluated by physical examination and standardized scoring instruments with an average follow-up of 4.0 years (range, 2.0-7.2). Twenty-one patients had full range of motion of the patella in all directions and a negative Hoffa test finding at final follow-up. All 14 (100%) patients with preoperative flexion contractures (>5 degrees ) experienced a full return of extension. The average Lysholm score improved from 59 preoperatively to 81 postoperatively (P < .0001). The average International Knee Documentation Committee (IKDC) score improved from 49 to 70 (P < .001). There were no complications. Four patients (16%) had failed results and required a second surgical release. Patients with failures had significantly lower preoperative Lysholm scores (score = 40) than those who did not (score = 58) (P = .022). Three of the failures were workers' compensation cases. CONCLUSION Scarring of the anterior interval changes the mechanics of the anterior structures of the knee and may lead to refractory anterior knee pain. Arthroscopic anterior interval release successfully provides pain relief in this patient population.

Abstract
PURPOSE To determine factors that cause reoperation after anterior cruciate ligament (ACL) reconstruction and determine which cause of reoperation can be addressed to help to improve technical aspects of the initial procedure. METHODS Between 1988 and 1998, 436 patients underwent an ACL reconstruction by a single surgeon. We analyzed all 207 patients who had a bone-patellar tendon-bone reconstruction (BPTB). The same technique was used in all operations, which consisted of the 1-incision endoscopic approach with autologous central third patellar-tendon graft. Of these patients, 196 were available for full evaluation. Evaluation included: a detailed history, physical examination, functional knee ligament testing, KT-1000 arthrometer testing, One-leg-hop testing, Lysholm score, Tegner score, and the International Knee Documentation Committee standard evaluation form. All technical surgical aspects concerning the index operation and the reoperations were collected and evaluated in detail to detect predictors for failure or improvement. Position of the graft was measured radiographically using the Amis circle and Taylor score. RESULTS The average age of the 196 patients at the time of the operation was 34 years, and the mean duration of follow-up was 7.4 years. Seventy-seven reoperations were performed in 54 (27.6%) patients during a period of 83 months postsurgery. Reoperations were done between day 22 and 83 months post-ACL reconstruction. Indications for reoperations were: pain caused by fixation material (n = 25); meniscal lesions (n = 24); cyclops lesion (n = 16); donor site morbidity (n = 5); re-rupture of the ACL (n = 5); posterior cruciate ligament rupture (n = 1); and a medial collateral ligament lesion (n = 1). A more ventral position of the graft on the femur (Amis <60%) was correlated with a higher frequency of meniscal lesions and cyclops lesions (P < .01). Patients who had a meniscal lesion after an ACL reconstruction had significantly lower Lysholm (P < .05) and Tegner scores (P < .01). CONCLUSIONS A large percentage of the patients (27.6%) required additional surgical procedures after patellar tendon autograft ACL reconstruction. A poor position of the graft resulted in cyclops and meniscal lesions. Analyzing the reasons for reoperations gives information about how to improve our surgical technique. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
Better understanding of surgical timing, improved surgical technique, and advanced rehabilitation protocols has led to decreased incidence of motion loss after anterior cruciate ligament injury and reconstruction. However, motion loss from high-energy, multiligament injuries continues to compromise functional outcome. Prevention, consisting of control of inflammation and early motion, remains the key element in avoiding motion loss. However, certain techniques, such as manipulation under anesthesia in conjunction with arthroscopic lysis of adhesions, are reliable treatment options. Open surgical débridement is rarely necessary and should be considered only as a salvage procedure. A greater understanding of the pathogenesis of arthrofibrosis and related inflammatory mediators may result in novel therapies for treating the patient with motion loss.

Abstract
The aim of the study was to see if delay in anterior cruciate ligament (ACL) reconstruction affects post-reconstruction outcome in recreational athletes. Sixty-two recreational athletes who had arthroscopic ACL reconstructions using quadruple hamstring grafts between 1997 and 2000 were retrospectively evaluated. Patients with less than 2 years' follow-up, those with multi-ligament injuries, reconstructions for previous failed repairs, those whose injury date was unknown, those with pre-injury Tegner activity level greater than 7 (competitive athletes) and those lost to follow-up were all excluded. Forty-six patients (38 males) were entered. The mean follow up was 38 months and the mean time from injury to index ACL reconstruction was 27 months. Apart from two revisions there were no other significant complications. Forty-one (89%) patients were evaluated in a review clinic. There was a significant improvement in the post-reconstruction Lysholm scores and an improvement in the Tegner scores. The Spearman's correlation coefficient between postoperative Lysholm score and the delay until surgery was -0.18 and the correlation coefficient between postoperative Tegner scores and the delay until surgery was 0.14. Thirty-five patients returned to sporting activity. Thirty-seven rated their knee as being normal or nearly normal and 35 said that their knee function was as they had expected it to be. Late ACL reconstruction does not adversely affect the outcome in recreational athletes. ACL reconstruction should be offered to these patients as there is a significant improvement in the knee function and patients are satisfied with the results.

Abstract
The management of motion loss of the knee is challenging. A clear understanding of the pathoanatomic causes of motion loss is necessary to establish a careful and rational approach to treatment. Early recognition and physical therapy are effective for the majority of patients, but when these conservative measures fail, operative intervention is indicated. The purpose of this article is to outline a comprehensive approach to the arthroscopic evaluation and treatment of the arthrofibrotic knee. This technique is designed to allow the surgeon to systematically address the numerous causes of motion loss of the knee.

Abstract
It has been our observation that post-operative anterior cruciate ligament (ACL) braces together with the post-operative bandages do not always allow the knee to reach full extension. In ten uninjured knees with known hyperextension, the knees were bandaged in the same way as after an ACL-reconstruction. The knees were then studied radiologically in a Hypex brace set at 0 degrees, -5 degrees and -10 degrees of knee extension. Not a single knee was found to be straight in the brace set at 0 degrees. At -5 degrees most of the knees were straight or in slight hyperextension. It took -10 degrees to get all knees straight or in hyperextension. In a prospective randomised study 44 patients who underwent an arthroscopic ACL-reconstruction with a bone patellar tendon bone graft were randomised to use either a brace set at -5 degrees or a straight brace (0 degrees ) for at least the first three postoperative weeks. Before and three months after surgery range of motion was determined, using a goniometer with long arms, and sagittal knee laxity was measured with a KT-2000 arthrometer at manual max. Pre- and post-operative pain was evaluated with the Visual Analogue Scale (VAS). The same examiner (blindfolded to what type of brace was used) performed all the measurements. At three months, two of the 22 patients with the brace set at -5 degrees and twelve of the 22 patients with the straight brace had a loss of full extension of 2 degrees or more ( p<0.001). No significant differences were found between the groups in terms of knee flexion, sagittal knee laxity or post-operative pain. Although extension deficit after ACL-reconstruction can be prevented also in other ways, a Hypex brace set at -5 degrees seems to be an easy way of ensuring full knee extension.

Abstract
Eighty patients with acute anterior cruciate ligament (ACL) reconstruction were compared to 80 patients with chronic ACL reconstruction. Before reconstruction, all patients had 0 degrees-120 degrees active motion, performed a straight leg raise without loss of extension, and demonstrated good quadriceps control. At 3 months, 4 acute patients had decreased range of motion (<10 degrees-120 degrees), but none at 6 or 12 months, and did not require repeat surgery. One chronic patient had decreased range of motion at 3 and 6 months and 1 patient had decreased range of motion at 1 year; both patients required operative intervention. Using these specific preoperative criteria, no increased incidence of decreased range of motion was found when an ACL reconstruction was performed within 3 weeks of injury.

Abstract
PURPOSE To describe the magnetic resonance (MR) imaging appearance of anterior cruciate ligament (ACL) stump entrapment in patients who presented with decreased knee extension after rupturing the ACL. MATERIALS AND METHODS MR images in 15 patients who had presented with a block to terminal knee extension after sustaining an ACL tear were retrospectively reviewed. The MR imaging appearances of entrapped ACL stumps were defined and correlated with arthroscopic and histologic findings. RESULTS The entrapped ACL stumps had two distinct appearances. Type 1 stumps (n = 11) were characterized by a nodular mass located at the anterior aspect of the intercondylar notch, interposed between the lateral femoral condyle and tibia. Type 2 stumps (n = 4) were characterized by a tonguelike free end and angulation of the stump. Histologic evaluation of the resected specimens showed distorted ACL fibers intermixed with variable fibrosis and inflammation. CONCLUSION Entrapment of an ACL stump can limit knee extension. The two observed appearances of entrapped ACL stumps likely represent two points along a spectrum of appearances, which possibly includes the cyclops lesion.

Abstract
Motion loss continues to be a difficult complication after ligament injury and surgery to the knee. A better understanding of the pathoanatomic causes of motion loss can lead to improved prevention and treatment strategies. When motion loss does occur, early recognition and appropriate treatment can be expected to restore motion and improve function in most patients. Treatment options, although varied, should improve outcome when implemented appropriately. This article is composed of two parts. The first part reviews the current concepts on definitions, incidence, and causes of motion loss. In the second part, to be published later, current strategies on prevention and treatment of motion loss after ligament injury to the knee are reviewed. Emphasis is placed on risk factors and prevention as well as on diagnosis and treatment. The article summarizes the latest information from the basic sciences as well as clinical studies on the problem of motion loss of the knee and attempts to provide a rational approach to these difficult clinical problems.

Abstract
Cyclops syndrome has been defined as a loss of knee extension due to impingement of a pedunculated proliferative tissue mass after anterior cruciate ligament reconstruction. We describe four patients who were operated on for progressive loss of knee extension after minor knee injury. During the arthroscopic procedure, the consistent finding was a fibrous pedunculated nodule adhering to the anterolateral aspect of the original anterior cruciate ligament, obstructing extension by impingement in the anterior aspect of the knee. At least part of the anterior cruciate ligament was intact in all cases. These patients were compared with seven patients who developed cyclops syndrome after anterior cruciate ligament reconstruction. Clinical and arthroscopic findings were the same in both groups. An arthroscopic excision of the nodule, performed an average of 12 weeks after knee trauma or after reconstruction, gave very good results. Histologic examination of the excised nodules from both groups showed fibroelastic connective tissue proliferation, thromboangiitis, and areas of necrotic bone and foreign body giant cell granuloma. On the basis of our observations, we conclude that formation of a fibrous pedunculated nodule may occur after an anterior cruciate ligament injury as well as after surgical reconstruction of the anterior cruciate ligament.

Abstract
Cyclops syndrome is one of the specific causes of loss of extension of the knee following anterior cruciate ligament (ACL) reconstruction. The syndrome is manifested by progressive loss of extension associated with pain and audible clunk at terminal extension caused by a pedunculated nodule of fibrovascular proliferative tissue usually arising from the graft. The entity has been described recently and has been reported exclusively as a complication of ACL reconstructions. We report the case of a patient with symptoms and arthroscopic and histological findings compatible with cyclops syndrome that developed after a partial ACL rupture that was not treated by surgical reconstruction. A different etiology and classical histological and immunohistological microscopic analysis of the nodule presented in this report may further clarify the pathogenesis of the cyclops syndrome.

Abstract
OBJECTIVE Localized anterior fibrosis (cyclops lesion) is a known cause of extension loss of the knee after anterior cruciate ligament (ACL) reconstruction. We describe MR imaging as a noninvasive diagnostic tool to examine cyclops lesions. SUBJECTS AND METHODS Thirty-three MR studies of 31 patients with residual persistent extension loss after ACL reconstruction using patellar tendon autograft were reviewed and compared with results of second arthroscopy. We used MR imaging to describe the ACL graft signal intensity and course, tibial and femoral tunnel placement. quantitative measurements of notch size and shape, and the presence or absence of cyclops lesions. When a cyclops lesion was revealed on MR imaging, the signal-intensity characteristics, location, and size were documented. Preoperative MR imaging findings were then correlated with findings at arthroscopy. RESULTS The sensitivity, specificity, and accuracy of revealing a cyclops lesion on MR imaging were 85.0%, 84.6%, and 84.8%, respectively. We found no statistically significant differences in the size of intercondylar notches for patients with and patients without cyclops lesions. CONCLUSION MR imaging was sensitive, specific, and accurate in revealing cyclops lesions in a subgroup of patients with extension loss after ACL reconstruction.

Abstract
Four patients presented with persistent diminution of knee motion after rupture of the anterior cruciate ligament with a novel lesion as the cause. Each had participated in an aggressive rehabilitation program for a minimum of 2 months with emphasis on regaining full range of knee motion. Because chronic impairment of knee extension can be disabling, in those who did not regain full range of motion, arthroscopy of the knee ensued. All had a lesion in the intercondylar notch near the tibial insertion of the anterior cruciate ligament that acted as a mechanical obstruction to full knee extension. Grossly and histologically, these were similar to the cyclops lesion that also has been shown to cause loss of knee extension after anterior cruciate ligament reconstruction. Arthroscopic debridement of the cyclops lesion and manual manipulation of the knee under anesthesia lead to restoration of full knee extension in all knees. In 1 other knee with chronic instability after anterior cruciate ligament rupture, the cyclops lesion was present but was very small and was not associated with diminished knee extension. When loss of full extension persists for 2 months after anterior cruciate ligament disruption despite aggressive rehabilitation, the presence of a cyclops lesion should be considered.

Abstract
Postoperative loss of knee motion is a well-recognized phenomenon. This paper reports our results with open debridement and soft tissue release as a salvage procedure in the treatment of patients with severe arthrofibrosis on whom arthroscopic surgical techniques had failed. Eight knees (eight patients) were identified retrospectively. There were four men and four women; mean age was 29 years. All had severely restricted motion with extensive intraarticular and periarticular fibrosis. Range of motion averaged 62.5 degrees preoperatively (flexion 81 degrees, loss of extension 18.8 degrees). Patients underwent open debridement and soft tissue release to restore motion. There were no complications. Motion improved to an average of 124 degrees after surgery. Average flexion improved from 81 degrees to 125 degrees . Loss of extension improved from 18.8 degrees to 1.25 degrees. Functional outcome was good, with Lysholm II scores averaging 79. Patient satisfaction was high. There was a high incidence of patellofemoral arthritis at follow-up. Furthermore, the patellar tendon shortened approximately 6 mm over time. While we do not advocate open debridement and soft tissue release as a first-line treatment for arthrofibrosis, we do conclude that it can be effective as a salvage procedure to restore motion in the profoundly arthrofibrotic knee.

Abstract
Patients with displaced bucket-handle (DBH) meniscal tears in anterior cruciate ligament (ACL)-deficient knees are prone to flexion contracture following meniscal repair and simultaneous ACL reconstruction. It has been suggested that ACL reconstruction be delayed until full range of motion has returned after the meniscal repair. A retrospective analysis was performed comparing the return of extension in patients undergoing simultaneous ACL reconstruction and repair of DBH tears (group A) versus a control group of patients with non-DBH tears (group B). Age, sex, body mass index, duration of time from injury to surgery, and preoperative extension were also compared between groups and evaluated for their significance as risk factors. Patients in group A achieved recovery to -5 degrees and 0 degrees of extension 22% and 35% more slowly, respectively, when compared with group B. These differences were not statistically significant. Female patients tended to heal more rapidly in both groups. We conclude that a one-stage procedure is sufficient in allowing patients with DBH tears in ACL-deficient knees to regain a functional knee to within 5 degrees of full extension.

Abstract
The most common complication of anterior cruciate ligament (ACL) reconstruction is loss of extension, which is often functionally worse for patients than their preoperative instability. Many preventable surgical and nonsurgical etiologic factors have been identified. Accurate placement of the tibial tunnel, adequate notchplasty, and the routing of the femoral side of the graft are all critical factors. Several studies report that early range-of-motion therapy emphasizing immediate postoperative "hyperextension" and avoiding immobilization in flexion reduces the rate of loss of extension. Initial studies investigating the effect of acute versus chronic ACL reconstruction suggested that acute reconstruction is associated with a higher rate of loss of extension. However, the authors of two recent studies in which modern techniques were used have disputed this conclusion. It is likely that the loss of extension historically seen with acute ACL reconstructions was related to tibial tunnel placement and postoperative immobilization. It is possible that the timing of acute ACL reconstruction has less of an effect than originally postulated. On the basis of the results of several biomechanical studies, it appears that ACL reconstruction may be performed with the knee in full extension during graft placement with excellent results and a very low rate of loss of extension. Use of the descriptive term "loss of extension" is preferred to the often misleading terms "arthrofibrosis" and "flexion contracture."

Abstract
Health care reform will quite possibly change the delivery of physical therapy by demanding physical therapists to be more accountable for providing appropriate, yet cost-effective treatment. The purpose of this study was to retrospectively compare the results after anterior cruciate ligament (ACL) reconstruction between two groups of patients with different numbers and frequencies of physical therapy visits postoperatively. Two random samples of 100 patients from a total of 1,345 patients identified as undergoing ACL reconstruction from 1990 through 1993 were included. Group A patients attended physical therapy regularly and participated in a home exercise program, while patients in Group B attended limited physical therapy visits and also performed a prescribed home exercise program. Both groups followed the same postoperative rehabilitation program for early range of motion, early weight bearing, and muscle control. The outcome variables measured 1, 6, and 12 months postoperatively included the number of structured visits to physical therapy, range of motion, isokinetic strength testing, and subjective rating. Group A averaged 20 visits in the first 6 months while Group B averaged seven visits. The results revealed no significant difference for flexion, isokinetic strength, or subjective rating. There was a significant difference for hyperextension (Group A, 2 degrees; Group B, 6 degrees). The results of this investigation indicated that by following a structured physical therapy program postoperatively, it is possible for patients to achieve a successful outcome with a limited number of routine physical therapy visits.
