Abstract
BACKGROUND Knee arthroscopic arthrolysis serves as an effective treatment for knee arthrofibrosis. However, hemarthrosis is the most common complication in arthroscopic surgery, which has potential adverse effects on postoperative rehabilitation. The purpose of this study was to evaluate the effects of topical tranexamic acid (TXA) in knee arthroscopic arthrolysis. METHODS A total of 87 patients with knee arthrofibrosis who underwent arthroscopic arthrolysis from September 2019 to June 2021 were eligible for this retrospective review. Patients in the TXA group (n = 47) received topical administration of TXA (50 mL, 10 mg/mL) at the end of the surgery, and patients in the control group (n = 40) received no TXA. The postoperative drainage volumes, hematologic levels, inflammatory marker levels, knee range of motion (ROM), visual analog scale (VAS) pain scores, Lysholm knee scores and complications were compared between the two groups. The curative effect of each group was calculated according to Judet's criteria. RESULTS The mean drainage volumes on postoperative day (POD) 1 and POD 2, and total drainage volume were significantly lower in the TXA group than in the control group (P < 0.001 for all). The TXA group had significantly lower postoperative CRP and IL-6 levels on POD 1 and POD 2, and at postoperative week (POW) 1 and POW 2 than the control group. The VAS pain scores in the TXA group were significantly lower on POD 1 and POD 2, and at POW 1 and POW 2 than those in the control group (P < 0.001 for all). Patients in the TXA group showed better postoperative ROM and Lysholm knee scores at POW 1 and POW 2. No patient had any complications such as deep venous thrombosis (DVT) or infection. The excellent and good rates of knee arthroscopic arthrolysis were comparable between the two groups at the sixth postoperative month (P = 0.536). CONCLUSIONS Topical administration of TXA in knee arthroscopic arthrolysis can reduce postoperative blood loss and inflammatory response, alleviate early postoperative pain, increase early postoperative knee ROM, and improve early postoperative knee function without increased risks.

Abstract
Open reduction and internal fixation is the gold standard treatment for tibial plateau fractures. However, the procedure is not free of complications such as knee stiffness, acute infection, chronic infection (osteomyelitis), malunion, non-union, and post-traumatic osteoarthritis. The treatment options for knee stiffness are mobilisation under anaesthesia (MUA) when the duration is less than 3 months, arthroscopic release when the duration is between 3 and 6 months, and open release for refractory cases or cases lasting more than 6 months. Early arthroscopic release can be associated with MUA. Regarding treatment of acute infection, if the fracture has healed, the hardware can be removed, and lavage and debridement can be performed along with antibiotic therapy. If the fracture has not healed, the hardware is retained, and lavage, debridement, and antibiotic therapy are performed (sometimes more than once until the fracture heals). Fracture stability is important not only for healing but also for resolving the infection. In cases of osteomyelitis, treatment should be performed in stages: aggressive debridement of devitalised tissue and bone, antibiotic spacing and temporary external fixation until the infection is resolved (first stage), followed by definitive surgery with grafting or soft tissue coverage depending on the bone defect (second stage). Intra-articular or extra-articular osteotomy is a good option to correct malunion in young, active patients without significant joint damage. When malunion is associated with extensive joint involvement or the initial cartilage damage has resulted in knee osteoarthritis, the surgical option is total knee arthroplasty.

Abstract
Posttraumatic arthrofibrosis is a common problem encountered in the orthopaedic setting for which there is no agreement on the optimal management strategy. The literature does not optimally describe the efficacy of arthroscopic lysis of adhesions for arthrofibrosis following tibial plateau fracture. The purpose of this study is to quantify the efficacy of arthroscopic lysis of adhesions with manipulation for the treatment of arthrofibrosis of the knee in patients who previously underwent surgical management of tibial plateau fracture. All patients who underwent arthroscopic lysis of adhesions from a single surgeon since 1999 were retrospectively reviewed. Clinical outcomes were evaluated by flexion, extension, and range of motion (ROM) preoperatively, intraoperatively, and postoperatively at intervals of 1, 4, 8, and 12 weeks, and any additional long-term follow-up. A total of 28 patients who had developed arthrofibrosis following surgical management of a tibial plateau fracture and failed nonsurgical management of knee stiffness were included in this study. There were significant improvements in total ROM following intervention at all time points compared with preoperative values (p < 0.001), with mean improvements of 59.3 degrees intraoperatively, 32.9 degrees (1 week), 37.1 degrees (4 weeks), 41.5 degrees (8 weeks), and 47.6 degrees (12 weeks). There were significant improvements in degrees of knee flexion following intervention at all time points compared with preoperative values (p < 0.001), with mean improvements of 50.8 degrees intraoperatively, 27.3 degrees (1 week), 36.0 degrees (4 weeks), 38.3 degrees (8 weeks), and 43.9 degrees (12 weeks). There were significant increases in degrees of knee extension intraoperatively (8.5 degrees) and at 1 week postoperatively (5.9 degrees) compared with preoperative values (p <0.01). At 12 weeks postoperatively, those who had previously undergone external fixation had significantly greater increases in ROM (p = 0.048). Arthroscopic lysis of adhesions for knee arthrofibrosis following surgical management of tibial plateau fracture significantly improves knee ROM.

Abstract
Arthrofibrosis is a devastating complication after Anterior Cruciate Ligament reconstruction (ACLr) characterized by a muscle weakness secondary to an arthrogenic muscle inhibition process. The loss of knee isokinetic strength due to arthrogenic muscle inhibition may be more important after arthrofibrosis, compared to an ACLr population with no complication. The isokinetic strength deficit [Limb Symmetry Index (LSI) at 60 and 180°/s of angular speed] was measured at 4, 7 and 12 post-operative months. Knee function, return to running and return to sport were evaluated. A comparison of the Quadriceps and the Hamstring LSI between patients with arthrofibrosis and those without post-operative complication was performed according to time and taking into consideration the type of surgical procedure. 539 primary ACLr patients were assessed. The arthrofibrosis group presented at 4, 7 and 12 post-operative months a Quadriceps LSI significantly lower compared to the control group, without influence of the graft procedure (LSI: 38, 53, 68% vs 63, 73, 85% at 60°/s, respectively). The Hamstring LSI was significantly lower at 4 and 7 post-operative months, but comparable at 12 months with an influence of the Hamstring procedure. Knee function was significantly lower at 4 and 7 post-operative months. Few arthrofibrosis ACLr patients returned to running at 7 post-operative months (6.8% vs 69.9%; p < .0001). An important and durable Quadriceps muscle weakness occurred after arthrofibrosis, whatever the type of graft procedure. This is explained by an Arthrogenic muscle inhibition which compromised the return to sport at the same level until 12 post-operative months. HighlightsAn important and durable quadriceps muscle weakness occurred after arthrofibrosis.The arthrogenic muscle inhibition was significant on the operated side independently of the type of the graft procedure.Arthrogenic muscle inhibition compromised the return to sport at the same level until 12 post-operative months.

Abstract
BACKGROUND Knee stiffness after trauma, fracture fixation, arthroscopic surgery, infection, and knee arthroplasty is a known complication, which is challenging to manage and causes significant disability to the patients. METHODS We did a comprehensive search on the stiff knees, in the last week of May 2020, from the search engines of PubMed, SCOPUS, Google Scholar, and Research Gates using the appropriate keywords. RESULTS We found two types of articles related to knees stiffness: (a) following trauma, internal and external fixation of fractures and arthroscopic surgery, and (b) following total knee arthroplasty. Arthroscopic surgery was found to be a favored mode of management of stiff knees in both of the above groups. The Manipulation under Anesthesia (MUA) was also found effective if done carefully and in the early course of the stiffness. CONCLUSION Knee stiffness due to any cause is a trouble proposition to both patients and treating surgeons. Various methods of management have been described to deal with knee stiffness. Amongst the operative treatment, MUA and arthroscopic surgery were found to be the most effective. Arthroscopic surgery offers a good option of release stiff knees in the majority of cases, and it is most valuable and effective if done earlier in the course of the stiffness (preferably between 3 and 6 months).

Abstract
PURPOSE The current study was conducted to evaluate the long-term clinical and radiological outcomes after arthroscopic arthrolysis for arthrofibrosis after anterior cruciate ligament reconstruction (ACLR). METHODS All patients treated with arthrolysis between 1990 and 1998 were included. Indication was arthrofibrosis in at least one knee compartment or a cyclops syndrome limiting range of motion (ROM) by > 5° of extension deficit and 15° of flexion deficit. International Knee Documentation Committee (IKDC) 2000 subjective and objective, Lysholm score, and x-ray evaluation were documented. Statistical analysis and power calculation were performed (P < .05). RESULTS One hundred forty-one patients (follow-up, 71%) were examined at a mean of 18.7 ± 2.6 years after arthroscopic arthrolysis. Mean IKDC 2000 score was 79.49 ± 14.32. IKDC objective was normal in 0%, nearly normal in 6%, abnormal in 56%, and severely abnormal in 38%. One hundred percent of patients showed more than grade II osteoarthritis. ROM improvement after arthrolysis did not change significantly compared with midterm results (t = 4.5 years). Patients with persisting motion deficits (P = .02) and after medial meniscus resection (P < .001) at time of ACLR showed significantly greater progression of osteoarthritis in comparison with patients without these additional disorders. In case of arthrolysis later than 1 year after ACLR, a more severe osteoarthritis grade (4% vs 20% grade III; P = .038) and a lower jump distance (IKDC: 61% A, 25% B vs 39% A, 41% B; P = .028) were obvious compared with patients who underwent arthrolysis within the first year after ACLR. CONCLUSIONS Long-term motion improvement can be achieved by arthrolysis. Persistent loss of motion resulted in a higher degree of osteoarthritis in the study population. Early intervention seems advisable as patients with arthrolysis later than 1 year after index surgery reached worse IKDC objective grading. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
PURPOSE Arthrofibrosis is a rare complication after anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to (1) report a population-based incidence of arthrofibrosis (as defined by manipulation under anaesthesia or surgical lysis of adhesions) following ACL injury and reconstruction, (2) identify risk factors associated with development of arthrofibrosis, and (3) report outcomes of intervention for arthrofibrosis. METHODS This was a historical cohort study performed in Olmsted County, Minnesota. The Rochester Epidemiology Project (REP) was used to identify a population-based cohort of individuals with new-onset, isolated ACL tears between 1 January 1990 and 31 December 2010. The REP database provides access to all medical records for each resident of Olmsted County, regardless of the facility where the care was delivered. A total of 1841 individuals were identified with new-onset, isolated ACL tears and were confirmed with chart review. The intervention incidence for arthrofibrosis was then calculated, and various predictive factors including age, sex, calendar year, and meniscal injury were investigated. RESULTS During follow-up, 5 patients (1.0 %) in the non-operative cohort and 23 patients (1.7 %) in the ACL reconstruction cohort received intervention for arthrofibrosis, corresponding to an incidence of 0.7 per 1000 person-years in the non-operative cohort and 1.9 per 1000 person-years in the ACL reconstruction cohort. Female patients were 2.5 times more likely to have arthrofibrosis than males. The mean preoperative range of motion was -8° to 83° and improved to a mean of -2° to 127° post-operatively. CONCLUSIONS Arthrofibrosis remains a rare but potentially devastating complication after ACL reconstruction, and roughly 2 % of patients had post-operative stiffness that required intervention. Female patients are at higher risk of arthrofibrosis. However, when patients develop severe motion complications after ACL injury, interventions are generally effective in preventing permanent arthrofibrosis.

Abstract
Post-traumatic knee stiffness and loss of range of motion is a common complication of injuries to the knee area. The causes of post-traumatic knee stiffness can be divided into flexion contractures, extension contractures, and combined contractures. Post-traumatic stiffness can be due to the presence of dense intra-articular adhesions and/or fibrotic transformation of peri-articular structures. Various open and arthroscopic surgical treatments are possible. A precise diagnosis and understanding of the pathology is mandatory prior to any surgical treatment. Failure is imminent if all pathologies are not addressed correctly. From a general point of view, a flexion contracture is due to posterior adhesions and/or anterior impingement. On the other hand, extension contractures are due to anterior adhesions and/or posterior impingement. This overview will describe the different modern surgical techniques for treating post-traumatic knee stiffness. Any bony impingements must be treated before soft tissue release is performed. Intra-articular stiff knees with a loss of flexion can be treated by an anterior arthroscopic arthrolysis. Extra-articular pathology causing a flexion contracture can be treated by open or endoscopic quadriceps release. Extension contractures can be treated by arthroscopic or open posterior arthrolysis. Postoperative care (analgesia, rehabilitation) is essential to maintaining the range of motion obtained intra-operatively.

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
Intra-articular inflammation or fibrosis may lead to decreased soft-tissue and capsular compliance, which may result in pain or loss of motion within the knee. Etiology of intra-articular fibrosis may include isolated anterior interval scarring and posterior capsular contracture, as well as fibrosis that involves the suprapatellar pouch or arthrofibrosis that involves the entire synovial space. Initial nonsurgical management, including compression, elevation, and physical therapy, can decrease knee pain and inflammation and maintain range of motion. Surgical management is indicated in the patient who fails conservative treatment. Surgical options include arthroscopic releases of the anterior interval, posterior capsule, and peripatellar and suprapatellar regions. Recent advances in arthroscopic technique have led to improved outcomes in patients with intra-articular fibrosis of the knee.

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 purpose of this study was to document the effect of arthroscopic management in patients with knee stiffness after total knee replacement. We present a case series study, in which 32 patients have been treated for moderate arthrofibrosis of the knee after total knee replacement, with the same regimen. We have excluded all cases of stiffness, because of infection, mechanical mal-alignment, loosening of the implants and other obvious reasons of stiffness of the knee, rather than pure arthrofibrosis. All patients first underwent a trial of conservative treatment before going for arthroscopic management. A pain catheter for femoral nerve block was inserted just before anesthesia for post-operative pain management. Arthroscopic arthrolysis of the intra-articular pathology was performed in a standardized technique with release of all fibrous bands in the suprapatellar pouch, reestablishing the medial and lateral gutter, release of the patella, resection of the remaining meniscal tissue or an anterior cyclops, if needed. Intensive physiotherapy and continuous passive motion were to start immediately post-operatively. All the patients were available for the follow up and they were evaluated using the knee society rating system. A total of 25 of the 32 procedures resulted in an improvement of the patients knee score. All the knees operated upon had intra-articular fibrous bands, hypertrophic synovitis and peri-patellar adhesions. A total of eight patients suffered from an anterior cyclops lesion and six patients showed pseudomenicus. In 19 cases a medial and lateral relapse of the patella was performed; only 5 patients got an isolated lateral release. The mean knee flexion was 119 degrees (100-130) at the end of arthroscopy and was 97 degrees (75-115) at the last follow up. The eight patients with extension lags decreased from 27 degrees (10 degrees-35 degrees) pre-operatively to 4 degrees (0-10) at time of follow up. The average knee society ratings increased from 70 points prior to the arthroscopy to 86 at time of follow up, which was found to be statistically significant (P < 0.01, student's t test). The average function score also showed improvement from 68 points pre-operatively to 85 at the time of final follow up. The average pain scores improved from 30 points pre-operatively to 41 at the time of final follow up. Our results showed that arthroscopic management of knee stiffness following total knee replacement is a safe and efficient method of treatment. Pain and functional knee scores can improve markedly.

Abstract
BACKGROUND To reduce the morbidity of traditional quadricepsplasty for the treatment of severe arthrofibrosis of the knee, we instituted a treatment regimen consisting of an initial extra-articular mini-invasive quadricepsplasty and subsequent intra-articular arthroscopic lysis of adhesions during the same anesthesia session. The purpose of the present study was to determine the results of this technique. METHODS From 1998 to 2001, twenty-two patients with severely arthrofibrotic knees were managed with this operative technique. The mean age of the patients at the time of the operation was thirty-seven years. After a mean duration of follow-up of forty-four months (minimum, twenty-four months), all patients were evaluated according to the criteria of Judet and The Hospital for Special Surgery knee-rating system. RESULTS The average maximum degree of flexion increased from 27 degrees preoperatively to 115 degrees at the time of the most recent follow-up (p < 0.001). According to the criteria of Judet, the result was excellent for sixteen knees, good for five, and fair for one. The average Hospital for Special Surgery knee score improved from 74 points preoperatively to 94 points at the time of the most recent follow-up (p < 0.001). A superficial wound infection occurred in one patient. Only one patient had a persistent 15 degrees extension lag. CONCLUSIONS This mini-invasive operation for the severely arthrofibrotic knee can be used to increase the range of motion and enhance functional outcome.

Abstract
Knee arthrofibrosis, which usually occurs after trauma or surgery, can inhibit joint biomechanics. An elaborated interaction of growth factors and other inflammatory mediators initiates and coordinates this deleterious tissue proliferation. Knowledge of risk factors can aid clinicians in helping patients avoid knee arthrofibrosis. Once the condition is present, a history and examination are imperative to institute the most appropriate treatment regimen. Nonoperative measures can be used as therapy, though surgery is often necessary for optimal results. We have analyzed problems in patient with uncommon evolution of knee arthrofibrosis following ACL recontruction with BTB autograft.

Abstract
INTRODUCTION Arthrofibrosis is a complication that severely influences the clinical outcome after anterior cruciate ligament (ACL) reconstruction. This retrospective clinical study analyses risk factors and outcome after arthrolysis in a large population. MATERIAL AND METHODS Two hundred twenty-three patients who had undergone arthrolysis after ACL reconstruction were examined. Range of motion (ROM) was reduced due to arthrofibrosis of the joint in 70% (n=156). Other reasons, such as cyclops syndrome or osteoarthritis were found in 30% (n=67). The mean time interval between arthrolysis and follow-up was 4.29 years. We recorded timing of surgery, additional injuries, state of the knee before reconstruction, range of motion, pain during rehabilitation, beginning, duration and type of rehabilitation, severity and etiology of joint stiffness and the time between ACL reconstruction and revision. The present state of the knee was documented using the IKDC form. RESULTS A significant correlation of arthrofibrosis and preoperative irritation (p<0.001), preoperative limited ROM (p=0.001), perioperative pain (p=0.046) and early beginning of muscle training (p=0.064) was found. Combination of a remaining loss of extension and development of degenerative joint disease was also significant (p=0.001). The decrease of sports activity compared with the level before ACL injury was highly significant (p<0.001). The criteria to minimize the risk of arthrofibrosis and the optimal timing of arthrolysis are pointed out.

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
This is the second part of a two-part review on motion problems after ligament injuries to the knee. The first part, published in the September/October 2001 issue, discussed normal and abnormal knee motion, terminology, risk factors, and pathoanatomy. The purpose of this article is to review current concepts on prevention and treatment of motion problems, summarizing the recent and pertinent studies that discuss this complicated clinical problem. The first part of this article will discuss the different classification schemes that have been published on motion loss of the knee. Prevention strategies will be discussed next, followed by early recognition. Finally, a discussion of the various treatment options and published results will be presented in detail, together with the authors' nine-step systematic surgical approach to the stiff knee.

Abstract
We present a new surgical subperiosteal endoscopic technique for the release of fibrosis of the quadriceps to the femur caused by gunshot injuries, postsurgical scarring, and fractures, that was developed at the Arthroscopy Group at Hospital Hermanos Ameijeiras in Havana, Cuba. The technique used is a proximal endoscopic subperiosteal extension of the usual arthroscopic intra-articular release of adhesions, using periosteal elevators and arthroscopic scissors placed through medial and lateral superior knee portals to release adhesions and bands of scar tissue beneath the quadriceps mechanism. The technique was used in a prospective case series of 26 male patients aged 19 to 22 years between February 1997 and March 1998 who presented with clinically and ultrasonically documented extra-articular fibrosis resulting in ankylosis of the knee in extension. Only patients who had reached a plateau in their aggressive physiotherapy program with no further progression in knee flexion for 3 months were selected. Those with joint instability, motion-limiting articular surface pathology, and muscle or neurologic injury were excluded. All patients had obtained satisfactory results at 2-year follow-up. The extra-articular release gained at final follow-up was between 30 degrees and 90 degrees of flexion in addition to that obtained at the completion of the standard intra-articular release. Complications included 1 case of deep vein thrombosis, 2 cases of scrotal edema, 5 cases of hemarthrosis, and 2 cases of reflex sympathetic dystrophy. We have found this technique useful in obtaining additional flexion and improved function in a difficult class of patients with ankylosis caused by extra-articular fibrosis of the quadriceps to the femur, allowing immediate aggressive rehabilitation and presenting a useful outpatient alternative with fewer and less severe complications than described with the classic open Thompson's quadricepsplasty.

Abstract
The cyclops lesion is a fibrous nodule with central granulation tissue located anterolateral to the tibial tunnel after intra-articular reconstruction of the anterior cruciate ligament (ACL) that has been shown to be a cause of failure to regain full extension in the early postoperative period. We present the case of a 23-year-old woman who had undergone arthroscopic ACL reconstruction with a patellar tendon autograft 4 years prior to presentation. Following her reconstruction, she regained full range of motion and returned to collegiate cheerleading. At presentation, she complained of a gradual loss of full extension and joint-line pain with terminal extension. On examination, her graft was stable and she lacked 3 degrees of extension. Magnetic resonance imaging documented a 1-cm mass of low signal intensity immediately anterior to the ACL graft within the intercondylar notch. At arthroscopy, a large amount of thick, immobile scar tissue was found immediately anterior to the ACL, consistent with a cyclops lesion. The lesion was debrided and the patient did well postoperatively. Patients who present with delayed-onset loss of extension after ACL reconstruction should undergo careful evaluation including radiographs and magnetic resonance imaging. If a cyclops lesion is diagnosed, arthroscopic resection should be undertaken.

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
We performed quantitative analysis of synovial fibrosis in the infrapatellar fat pad in 26 patients who underwent arthroscopically assisted anterior cruciate ligament reconstructions. Twelve patients underwent reconstruction with patellar tendon autografts, and 14 had reconstructions with semitendinosus and gracilis tendon autografts. Synovial samples were obtained at the time of reconstruction from 10 patients and at second-look arthroscopy from all 26 patients. Sections from quick-frozen samples were stained with either hematoxylin and eosin or Fast green and Sirius red. We used sodium hydroxide in absolute methanol to elute the Fast green and Sirius red stains, and the total collagen content of each section was estimated by measuring the optical density of the eluted solution. The volume of each section was determined on a computer using an imaging program, and collagen content per unit of tissue was calculated. Median collagen content was 15.3 micrograms/mm3 for the preoperative samples, 25.1 micrograms/mm3 for the group with patellar tendon autografts, and 27.1 micrograms/mm3 for the group with hamstring tendons autografts. Analysis of preoperative and postoperative paired samples revealed a significant increase in synovial collagen after anterior cruciate ligament reconstruction. We observed increased fibrosis in patients who had pain on exertion or stiffness in squatting after the reconstructive surgery.

Abstract
We report 72 patients with disabling knee arthrofibrosis who were treated at our clinic. All patients had painful restriction of extension or limitation of both extension and flexion that had persisted despite physical therapy. The level of arthrofibrosis was categorized into one of four types: Type 1 (25 patients), < 10 degree extension loss and normal flexion; Type 2 (16 patients), > 10 degree extension loss and normal flexion; Type 3 (15 patients), > 10 degree extension loss and > 25 degree flexion loss with a tight patella; and Type 4 (16 patients), > 10 degree extension loss, 30 degrees or more flexion loss, and patella infera with marked patellar tightness. All patients were treated with outpatient arthroscopic surgery. Anterior scar resection down to the proximal tibia was required for all patients with Types 2, 3, and 4 arthrofibrosis. Notchplasty was performed when necessary. Medial and lateral capsular releases and knee manipulation were required for patients with Type 3 or 4 arthrofibrosis. Postoperatively, all patients with Types 2, 3, and 4 arthrofibrosis were treated with outpatient serial extension casting. At the time of latest followup (28 to 115 months), the mean improvement of range of motion was as follows: Type 1, 7 degrees of extension; Type 2, 14 degrees of extension; Type 3, 13 degrees of extension and 28 degrees of flexion; and Type 4, 18 degrees of extension and 27 degrees of flexion. Improvement was also found for the mean stiffness, self-evaluation, functional activity, and Noyes knee scores in all groups.

Abstract
We prospectively studied 31 knee arthrolyses performed for loss of motion after intra-articular anterior cruciate ligament (ACL) reconstruction. The arthrolysis was performed on average 10.6 months after the reconstruction (range 4-25). Seven knees were localized forms. They were treated with arthroscopic removal of a fibrous nodule and scar tissue anterior to the ACL, which was preserved. Twenty-four knees were global forms and treated arthroscopically (14) or in open procedure (10). Suprapatellar, medial, and lateral gutter adhesions were sectioned, and fibrous tissue was removed from the anterior compartment. A posteromedial and/or posterolateral capsulotomy was necessary in 7 knees. The ACL graft was nonfunctional and/or malpositioned in 19 knees. The results were evaluated with the IKDC form with an average follow-up of 3.5 years (range 1.5-7). Preoperatively the localized forms had an average extension loss of 11 degrees and an average flexion loss of 14 degrees compared to the opposite knee. At follow-up all the knees were satisfactory for symptoms. All except one achieved a satisfactory motion (within 5 degrees of extension loss and 15 degrees of flexion loss) and a satisfactory final result. Global forms had a greater preoperative flexion loss (average 34 degrees) and extension loss (average 17 degrees). At follow-up 58% were satisfactory for symptoms and 71% for arc of motion. However, the final result was satisfactory in only 37%. In conclusion, local forms have a good prognosis. In global forms motion may be improved by surgery, but the final result is downgraded by symptoms. Arthrolyses performed within 8 months from index operation had a better outcome.
