[PMID: 38408714 DOI: 10.1016/j.arth.2024.02.057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 02/15/2024] [Accepted: 02/19/2024] [Indexed: 02/28/2024] Open
Abstract
BACKGROUND Recent literature has suggested that knee arthroscopy (KA) following ipsilateral primary total knee arthroplasty (TKA) may be associated with an increased risk of periprosthetic joint infection (PJI). However, prior studies on this subject have relied on insurance databases or have lacked control groups for comparison. This study aimed to evaluate the risk of PJI in patients undergoing ipsilateral KA after primary TKA at a single institution. METHODS Our total joint registry was queried to identify 167 patients (178 knees) who underwent ipsilateral KA for any indication other than infection following primary TKA (KA + TKA group). The average time from TKA to KA was 2.1 ± 2.3 years. The average follow-up from primary TKA and from KA was 8.4 ± 5.4 years and 6.3 ± 5.4 years, respectively. The mean patient age was 63 ± 11 years, the mean body mass index was 31 ± 5, and 64% were women. The most common indications for KA were patellar clunk or patellofemoral synovial hyperplasia (66%) and arthrofibrosis (16%). Patients in the KA + TKA group were matched to 523 patients who underwent TKA without subsequent KA (TKA group) based on age, sex, date of surgery, and body mass index. The primary outcome measure was survivorship free from PJI. RESULTS There was no statistical difference in the overall rate of PJI between the KA + TKA group (n = 2, 1.1%) compared to the TKA group (n = 3, 0.6%) (hazard ratio 2.0, 95% confidence interval 0.3 to 12.0, P = .4). At 5 and 10 years after TKA, there was no difference in survivorship free of PJI between the 2 groups (P = .8 and P = .3, respectively). CONCLUSIONS A PJI is a rare complication of KA after TKA. The rate of PJI in patients undergoing KA following TKA is not significantly increased. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND The relationship between inferior patellar mobility (IPM) and knee flexion angle has yet to be elucidated. This study aimed to develop quantitative IPM measurement methods and clarify the relationship between IPM and knee flexion angle in community-dwelling older females. METHODS This was a cross-sectional study. Overall, 128 healthy older women (age 65-79 years) were recruited from the community to evaluate the relationship between IPM and knee flexion angle. This study was performed between May 2015 and December 2017. The reference value of and sex differences in IPM were evaluated in 205 healthy young adults aged between 19 and 21 years. IPM was compared between healthy older and young women and was objectively measured using our specially designed patellofemoral arthrometer (PFA). Patellar mobility was calculated by normalization to body height. IPM reliability was assessed before all measurements. RESULTS Intraclass correlation coefficients for intratester and intertester reliabilities varied from 0.87 to 0.99. The normal range based on two standard deviations of inferior patellar displacement/body height was 5.9-13.5% (young men), 5.1-14.3% (young women), and 1.2-8.8% (older women). IPM was significantly lower in older than young women (P < 0.001). There was a significant positive correlation (r = 0.72 and P < 0.01) between IPM and knee flexion angle in healthy older women unable to flex the knee joint fully. CONCLUSIONS Our PFA has good intratester and intertester reliability. The results suggest that IPM decreases with aging in women. IPM and knee flexion angle are correlated among older women unable to flex the knee joint fully. CLINICAL TRIAL REGISTRATION Not applicable.

High Complication Rate Associated With Arthroscopic Lysis of Adhesions Versus Manipulation Under Anesthesia for Arthrofibrosis After Total Knee Arthroplasty. J Am Acad Orthop Surg 2023; 31:e216-e225. [PMID: 36728979 DOI: 10.5435/jaaos-d-22-00430] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Accepted: 10/09/2022] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Arthrofibrosis after total knee arthroplasty (TKA) is often treated by arthroscopic lysis of adhesions (ALAs) or manipulation under anesthesia (MUA). This study compared the 2-year complication rates of ALA and MUA and range-of-motion (ROM) outcomes for ALA, early MUA (<3 months after TKA), and delayed MUA (>3 months after TKA). METHODS This retrospective cohort study included 425 patients undergoing ALA or MUA after primary TKA from 2001 to 2018. Demographics, clinical variables, and complication rates were collected from clinical records and compared using Student t -tests and Kaplan-Meier log-rank tests. Multivariable logistic regressions were used for adjusted analysis. ROM data were analyzed using fixed and mixed-effects models. RESULTS ALA patients were younger (55.2 versus 58.9 years, P < 0.001) and underwent surgery later from the index TKA (12 versus 1.9 months, P < 0.001). The Charlson Comorbidity Index was higher in the MUA group. Preoperative ROM was significantly worse in the MUA cohort, but did not differ between groups after the procedure (117°, P = 0.27) or at 2 years. Demographics and ROM outcomes were equivalent between early MUA and delayed MUA ( P = 0.75). The incidence of repeat arthrofibrosis (7.1%) and revision arthroplasty (2.4%) was similar between ALA and MUA cohorts while ALA patients had significantly more surgical site infections (3.8%) compared with MUA patients (0.47%, P = 0.017). DISCUSSION Equivalent ROM outcomes were seen between ALA, early MUA, and delayed MUA for the treatment of arthrofibrosis after TKA. However, this study demonstrated a markedly higher complication rate, particularly surgical site infection, after ALA, suggesting that MUA may be the preferred option for treating arthrofibrosis at both early and late time points.

Abstract
Total knee arthroplasty (TKA) results in substantial improvement for most patients with end-stage arthritis of the knee; however, approximately 20% of patients have an unsatisfactory result. Although many problems contributing to an unsatisfactory result after TKA are best addressed by revision TKA, some problems may be effectively addressed with arthroscopic treatment. The categories of pathology that can be addressed arthroscopically include peripatellar soft-tissue impingement (patellar clunk syndrome and patellar synovial hyperplasia), arthrofibrosis, and popliteus tendon dysfunction. Recognizing these disease entities and the role of arthroscopic surgery in the treatment of these lesions may be helpful in achieving a good outcome in certain patients who are unsatisfied with their knee arthroplasty.

Abstract
Introduction Most patients undergoing total knee arthroplasty (TKA) experience favorable outcomes. Some patients, however, experience prolonged post-operative knee pain and tenderness at the joint line. This has been attributed in some cases to soft tissue impingement due to pseudomeniscus. The purpose of this study is to evaluate patient outcomes for arthroscopic excision of pseudomeniscus for persistent knee pain after TKA and to perform a review of literature for pseudomeniscus after knee arthroplasty. Methods A retrospective analysis of patients undergoing arthroscopy to remove soft tissue causing persistent knee pain after previous TKA was performed. Outcome scores were asked at three time points: prior to knee arthroplasty, prior to arthroscopy, and post-arthroscopy at final follow-up. Subjective satisfaction with surgery and willingness to repeat procedures were also recorded. A two-tailed distribution paired t-test was used to determine statistical significance (p < 0.05). We also performed a review of the literature for pseudomeniscus complications for comparison. Results Nine out of eleven patients were considered eligible to be assessed for post-operative satisfaction. Seven out of nine patients reported complete satisfaction and eight participants stated they would undergo the procedures again if they have to. Among 9 included patients, five patients have successfully completed the clinical score evaluation survey. The mean age of the patients with clinical score evaluation at the time of TKA was 61 years (range, 53-72) and the time between TKA and undergoing arthroscopy was 8 months (range, 5-13). The average follow-up period for patient-determined assessment after the arthroscopic procedure was 71 months (range, 16-115). All 5 patients reported improved Oxford Knee Scores (p=0.017), Western Ontario and McMaster Universities Osteoarthritis Index (p=0.023), and pain scores (p=0.018) comparing pre-arthroscopy to post-arthroscopy at follow-up. Conclusion Arthroscopic removal of pseudomeniscus after TKA provides promising results in patients who experience persistent knee joint line pain and tenderness. Considering our results and review of literature, we recommend including pseudomeniscus in the differential for post arthroplasty knee pain. Study design Case series with a review of literature.

Abstract
Background Arthroscopic lysis of adhesions is a treatment option for patients with painful, stiff knees as a result of arthrofibrosis following knee arthroplasty, in whom prior manipulation under anesthesia (MUA) has failed. Typically, nonoperative treatment in these patients has also failed, including aggressive physiotherapy, stretching, dynamic splinting, and various pain-management measures or medications. Range of motion in these patients is often suboptimal, and any gains in flexibility will likely have hit a plateau over many months. The goal of performing lysis of adhesions is to increase the range of motion in patients with knee stiffness following total knee arthroplasty, as well as to reduce pain and restore physiologic function of the knee, enabling activities of daily living. Description This is a straightforward surgical technique that can be performed in a single stage. The preoperative range of motion is documented after induction of general anesthesia. The procedure begins with the establishment of standard medial and lateral parapatellar arthroscopic portals. A blunt trocar is introduced into the knee, and blunt, manual lysis of adhesions is performed in the suprapatellar pouch and the medial and lateral gutters with use of a sweeping motion after piercing and perforating the scarred adhesive bands or capsular tissue. Next, the arthroscope is inserted into the knee, and a diagnostic arthroscopy is performed. Bands of fibrous tissue are released and resected with use of electrocautery and a 4.0-mm arthroscopic shaver. Next, the posterior cruciate ligament (PCL) is visualized in full flexion. If PCL tightness is observed, the PCL can be released from its femoral origin until the flexion gap is increased. This portion of the procedure can include either partial or full release of the PCL, as indicated. Next, the arthroscope is removed and the ipsilateral hip is flexed to 90° for a standard MUA. Gentle force is applied to the proximal aspect of the tibia, and the knee is flexed. After completing the MUA, immediate post-intervention range of motion of the knee is documented, and the patient is provided with a continuous passive motion (CPM) machine set to the maximum flexion and extension achieved in the operating room. Alternatives Nonoperative treatment of a stiff knee following total knee arthroplasty is well documented in the current literature. Range of motion has been shown to increase in patients undergoing proper pain management, aggressive physical therapy, and closed MUA in the acute postoperative setting. Additionally, more severe cases of established arthrofibrosis despite prior MUA can be treated with an open lysis of adhesions1-3. Rationale Arthroscopic lysis of adhesions with PCL release versus resection has been well described previously. This procedure has been shown to benefit patients in whom initial nonoperative treatment has failed. Additionally, this procedure is not limited to the immediate acute postoperative period like standard MUA3. To our knowledge, no technique video has been published outlining arthroscopic lysis of adhesions for a stiff knee following total knee arthroplasty. Expected Outcomes This procedure has been shown to provide an immediate and lasting improvement in the flexion and extension arc of the knee, as well as improved functional outcomes. Patients should be educated that improvements gained in the operating room must be sustained through physical therapy. In a study of 32 patients who underwent arthroscopic lysis of adhesions for moderately severe arthrofibrosis following a total knee arthroplasty, Jerosch and Aldawoudy reported a mean postoperative flexion of 119° in the operating room and 97° at the time of the latest follow-up. Eight patients with extensor lag showed improvement from 27° to 4°. Average Knee Society scores improved from 70 points preoperatively to 86 points at the time of the latest follow-up4. Their article showed that arthroscopic treatment of stiffness following total knee arthroplasty is a safe and effective form of treatment. Important Tips Perform manual lysis of adhesions with a trocar prior to inserting the arthroscope in order to improve visualization and access.Utilize all portals and accessory portals interchangeably in order to improve access.Prescribe physical therapy with or without CPM machine immediately following surgery in order to maintain correction.Utilize pump inflow in order to help distend the tightened capsule.Protect the prosthetic surface from scratches during portal establishment.Loss of flexion implies scarring in the suprapatellar pouch and/or intercondylar notch, or PCL tightness.Loss of extension implies a tight posterior capsule, posterior osteophytes, or scarring of the PCL stump.A motorized shaver is the best tool for treatment of dense fibrous tissue, but be sure not to scratch metal total knee components.

Abstract
Arthrofibrosis following total knee arthroplasty (TKA) is a debilitating condition typically diagnosed based on clinical findings. To gain insight into the histopathologic immune cell microenvironment of arthrofibrosis, we assessed the extent of tissue fibrosis and quantified immune cell populations in specific tissue regions of the posterior capsule. We investigated specimens from three prospectively-collected, matched cohorts, grouped as patients receiving a primary TKA for osteoarthritis, revision TKA for arthrofibrosis, and revision TKA for non-arthrofibrotic, non-infectious reasons. Specimens were evaluated using hematoxylin and eosin staining, picrosirius red staining, immunofluorescence, and immunohistochemistry with Aperio®-based digital image analysis. Increased collagen deposition and increased number of α-SMA/ACTA2 expressing myofibroblasts were present in the arthrofibrosis group compared to the two non-arthrofibrotic groups. CD163 + macrophages were the most abundant immune cell type in any capsular sample with specific enrichment in the synovial tissue. CD163 + macrophages were significantly decreased in the fibrotic tissue region of arthrofibrosis patients compared to the patients with primary TKA, and significantly increased in adipose tissue region of arthrofibrotic specimens compared to non-arthrofibrotic specimens. Synovial CD117 + mast cells were significantly decreased in arthrofibrotic adipose tissue. Together, these findings inform diagnostic and targeted therapeutic strategies by providing insight into the underlying pathogenetic mechanisms of arthrofibrosis.

Abstract
INTRODUCTION Arthrofibrosis develops in 3-10% of knees after total knee arthroplasty (TKA), which may result in pain and restricted range-of-motion. Treatment options include manipulation under anaesthesia, arthroscopic debridement, and quadricepsplasty, but there is little consensus on their efficacy for treatment of unexplained pain after TKA. The purpose of this study was to report the prevalence and characteristics of unexplained pain after TKA as revealed by arthroscopic exploration, and assess the efficacy of arthroscopic procedures to relieve pain. MATERIALS AND METHODS From a consecutive series of 684 TKAs, 11 patients (1.6%) had unexplained pain at 7-48 months after TKA. Causes of pain remained unidentified after systematic and differential assessment, but arthroscopic exploration revealed fibrotic tissues, which were debrided during the same procedure. Patients were assessed first at 6-61 months and last at 90-148 months, with pain on a visual analog scale (pVAS) and range-of-motion recorded during both assessments, but Oxford Knee Score (OKS) and Forgotten Joint Score (FJS) only during the last assessment. Residual pain was classified as little or no pain (pVAS, 0-1), moderate pain (pVAS, 2-4), and severe pain (pVAS, 5-10). RESULTS At first follow-up (n = 11) pVAS improved by 4.1 ± 1.1 (p < 0.001), and range-of-motion improved by 5.0° ± 7.1° (p = 0.041). Seven patients (64%) had little or no residual pain, while four (36%) had moderate residual pain. At final follow-up (n = 9) pVAS improved by 3.2 ± 2.9 (p < 0.001), and range-of-motion improved by 4.4° ± 8.5° (p = 0.154). Six patients (67%) had little or no residual pain, while one (11%) had moderate and two (22%) had severe residual pain. CONCLUSION Arthroscopic exploration revealed that all 11 knees with unexplained pain had fibrotic tissues, the removal of which alleviated pain in only 67%, while moderate to severe pain persisted in 33% which merits further scrutiny.

Abstract
Fixed flexion deformity also called flexion contracture is relatively rare, but a very demanding functional limitation that both surgeons and patients may have to deal with. The purpose of the present study was to evaluate the functional outcomes after posteromedial capsular release in case of fixed flexed deformity > 15 o . Between June 2011 and November 2018, 15 patients (6 males and 9 females) were treated with open posterior capsular release through medial approach for fixed flexion deformity of the knee > 15 o and prospectively followed with a minimum follow-up of 2 years. Primary outcome was knee extension measured with a manual goniometer and secondary outcome treatment related complications. All patients reported inability to walk and clinical semiology of pain and swelling. The mean age of the study population at surgery was 61.7 years with a mean BMI of 30.9 kg/m2. Complete data were recorded for all patients. Statistically significant improvement was found in clinical and functional assessment tools analyzed from baseline to the latest follow-up (p<0.05). More precisely, the mean postoperative fixed flexion deformity was decreased from 23.57 o to 2.86 o . No adverse effect or major complications were recorded during follow-up.
Posterior open release via posteromedial was shown to be an efficient and safe salvage procedure to deal with persistent fixed flexion deformity of more than 15 o following TKA at two years follow-up. However, future studies with a higher number of participants and longer follow-up should be conducted to validate our data.

Abstract
PURPOSE There is currently no consensus regarding the optimal treatment for stiffness following total knee arthroplasty (TKA). With the increased utilization of value-based models, it is important to determine the most effective treatments that will reduce the need for further intervention and additional expenditure. A systematic review was performed to compare the outcomes of manipulation under anaesthesia (MUA), arthroscopic lysis of adhesions (aLOA), and revision TKA (rTKA) for arthrofibrosis and stiffness following TKA. METHODS PubMed and MEDLINE databases were reviewed for articles published through October 2020. Studies were included if they reported patient-reported outcome measures (PROMs) following MUA, aLOA, or rTKA. The primary endpoint was PROMs, while secondary outcomes included range of motion and the percentage of patients who pursued further treatment for stiffness. RESULTS A total of 40 studies were included: 21 on rTKA, 7 on aLOA, and 14 on MUA. The mean or median post-operative arc ROM was > 90° in 6/20 (30%) rTKA, 5/7 (71%) aLOA, and 7/10 (70%) MUA studies. Post-operative Knee Society (KSS) clinical and functional scores were the greatest in patients who underwent MUA and aLOA. As many as 43% of rTKA patients required further care compared to 25% of aLOA and 17% of MUA patients. CONCLUSION Stiffness following TKA remains a challenging condition to treat. Nonetheless, current evidence suggests that patients who undergo rTKA have poorer clinical outcomes and a greater need for further treatment compared to patients who undergo MUA or aLOA.

Abstract
Aims Outcomes of current operative treatments for arthrofibrosis after total knee arthroplasty (TKA) are not consistently positive or predictable. Pharmacological in vivo studies have focused mostly on prevention of arthrofibrosis. This study used a rabbit model to evaluate intra-articular (IA) effects of celecoxib in treating contracted knees alone, or in combination with capsular release. Methods A total of 24 rabbits underwent contracture-forming surgery with knee immobilization followed by remobilization surgery at eight weeks. At remobilization, one cohort underwent capsular release (n = 12), while the other cohort did not (n = 12). Both groups were divided into two subcohorts (n = 6 each) – one receiving IA injections of celecoxib, and the other receiving injections of vehicle solution (injections every day for two weeks after remobilization). Passive extension angle (PEA) was assessed in live rabbits at 10, 16, and 24 weeks, and disarticulated limbs were analyzed for capsular stiffness at 24 weeks. Results IA celecoxib resulted in greater mean PEA at ten weeks (69.6° (SD 4.6) vs 45.2° (SD 9.6), p = 0.004), 16 weeks (109.8° (SD 24.2) vs 60.9° (SD10.9), p = 0.004), and 24 weeks (101.0° (SD 8.0) vs 66.3° (SD 5.8), p = 0.004). Capsular stiffness was significantly reduced with IA celecoxib (2.72 Newton per cm (N·cm)/° (SD 1.04), p = 0.008), capsular release (2.41 N·cm/° (SD 0.80), p = 0.008), and capsular release combined with IA celecoxib (3.56 N·cm/° (SD 0.99), p = 0.018) relative to IA vehicle (6.09 N·cm/° (SD 1.64)). Conclusion IA injections of a celecoxib led to significant improvements in passive extension angles, with reduced capsular stiffness, when administered to rabbit knees with established experimental contracture. Celecoxib was superior to surgical release, and the combination of celecoxib and a surgical release did not provide any additional value. Cite this article: Bone Joint Res 2022;11(1):32–39.

Abstract
Stiffness after total knee arthroplasty (TKA) remains a clinical challenge for health care professionals. Historically, arthroscopic arthrolysis is a treatment modality that has been reserved for patients that have failed other conservative modalities, including manipulation under anesthesia. However, a systematic review of the literature evaluating the clinical efficacy and complications of arthroscopic arthrolysis for stiffness after TKA has not been performed. A systematic review of medical databases (PubMed, EMBASE, Cochrane Library) was undertaken for articles published from January 1980 to October 2018. A descriptive and critical analysis of the results was performed. From 1,326 studies, 7 studies met the inclusion criteria for this study. A total of 160 patients who underwent arthroscopic arthrolysis for arthrofibrosis following TKA were included for analysis. The quality of the evidence for the included studies ranged between moderate and high. Overall, patients had significant increased range of motion and flexion by 32.5 and 26.7 degrees, respectively following arthroscopic arthrolysis. Functional outcome scores also significantly improved for patients who underwent arthroscopic arthrolysis after TKA. Arthroscopic arthrolysis is an efficacious modality for treatment of stiffness following TKA. The greatest benefit is seen among patients that present with significant loss of flexion. Arthroscopic arthrolysis should be reserved for patients that have previously failed more conservative modalities.

Abstract
Background: To clarify the changes in the echo intensity (EI) in the prefemoral fat pad (PFP) and identify the relationship between the PFP and clinical features of knee osteoarthritis (OA). Methods: Twenty-six women with knee OA (mean age: 76 years) and 17 healthy women (mean age: 73 years) were enrolled. The Kellgren and Lawrence grading scale was used for the radiographic evaluation of knee OA. The EI of the PFP was measured as grayscale values. The change ratio of the anteroposterior PFP length during quadriceps contraction was measured. Knee range of motion and pain (100-mm visual analog scale) were evaluated. Results: The EI was significantly higher in the OA group than in the healthy group (P < 0.001). The change ratio of the PFP in the OA group was significantly lower than that in the healthy group (P < 0.001). The ranges of knee flexion and extension were correlated with the EI of the PFP (both P < 0.01) and the change ratio of the PFP (both P < 0.01). There was no significant correlation observed with knee pain. Conclusion: Hyperechoic changes and a decreased change ratio of the PFP were observed in the patients with knee OA. High EI and decreased morphological PFP changes were associated with decreased ranges of motion.

Abstract
BACKGROUND Outcomes of knee arthroscopy (KA) after total knee arthroplasty (TKA) have been limited to small case series with short-term follow-up. The purpose of this study is to report the outcomes of patients who undergo a KA after a TKA using a large longitudinal database. METHODS The PearlDiver Medicare database was queried for patients who underwent a KA procedure after a TKA on the ipsilateral extremity. A randomly selected control group was created by matching controls to cases in a 3:1 ratio based on age, gender, year of procedure, and Elixhauser Comorbidity Index. Revision for infection and all-cause revision were used as end points. RESULTS A total of192 TKA patients who underwent a subsequent KA (TKA + KA group) were compared to 571 TKA patients who did not have a subsequent KA (TKA - KA group). The incidence of revision for infection was 6.3% in the TKA + KA group compared to 2.2% in the TKA - KA group (odds ratio, 2.87; P = .009). The incidence of all-cause revision was 18.8% in the TKA + KA group compared to 5.1% in the TKA - KA group (odds ratio, 4.34; P < .001). CONCLUSION KA after TKA was associated with increased infection-related and all-cause revision. The association between KA and subsequent infection requires further investigation.

Abstract
Background Arthrofibrosis is a known complication of total knee arthroplasty (TKA). Closed manipulation is the treatment of choice for arthrofibrosis within 90 days of TKA. Treatment for arthrofibrosis that has failed prior interventions remains controversial, and the role for arthroscopic lysis of adhesions has not been examined for late-presenting arthrofibrosis. Methods A retrospective analysis of patients who underwent arthroscopic lysis of adhesions (LOAs) with manipulation for post-TKA arthrofibrosis was performed. Chart review included patient characteristics, time from TKA, prior interventions, and range of motion (ROM) data. Knee extension, flexion, and total ROM were recorded preoperatively, intraoperatively, and throughout follow-up. Knee ROM was compared at the different time intervals using Wilcoxon signed-rank tests. Results A total of 13 patients (6 male and 7 female) with a mean age of 66.3 years were included. Average time since index TKA was 57.2 months (3.7-209.5). Ten of 13 patients had undergone prior interventions for arthrofibrosis, which included closed manipulation under anesthesia, open LOA, and revision arthroplasty. The mean preoperative knee flexion and extension values for the cohort were 76.5 ± 17.4 and −4.6 ± 6.1 degrees, respectively. Postoperative improvements in knee ROM were significant at all time points, with mean improvements of 17.2 ± 16.3 degrees at 1 week (P = .022), 17.2 ± 13.2 degrees at 4 weeks (P = .001), 19.2 ± 16.0 degrees at 8 weeks (P = .004), and 25.2 ± 13.1 degrees at 12 weeks (P = .005). No complications were recorded. Conclusions Arthroscopic LOAs with manipulation achieves significant improvements in knee ROM for late-presenting arthrofibrosis after TKA.

Abstract
Background: The development of contractures after total knee replacement is most often associated with arthrofibrosis and makes up 1.3% - 5.7% of the total number of cases of joint replacement. Conservative treatment is ineffective. Arthrolysis is pathogenetically substantiated (arthroscopic or open).
Aims: assessment of the effectiveness of arthrolysis as a method of treating knee joint contractures after arthroplasty, comparison of the results of arthroscopic and open arthrolysis, analysis of complications.
Materials and methods: Compare two groups. In group 1, 57 patients underwent arthroscopic arthrolysis. In group 2, 54 patients underwent open arthrolysis. The operations were performed from 2015 to 2019, the observation period ranged from one year to three years. As criteria for the result of treatment, KSS data were used (general and functional assessment of the knee joint), as well as separately the amplitude of movements in the joint before surgery and at different times after it.
Results: One of the results of this work was the optimization of arthroscopic arthrolysis technique. Improved surgical access and joint revision sequence. According to the KSS scale and range of motion, the best results were obtained in group 1. Especially important is the lesser number of complications in comparison with the 2nd group requiring repeated interventions, including revision arthroplasty. In the 1st group of such cases there were 3 (5.3%), in the 2nd group - 7 (13.0%).
Conclusions: Arthroscopic arthrolysis is a less traumatic and more effective treatment for arthritis of the knee. It seems appropriate to gradually displace open arthrolysis by arthroscopic.

Abstract
The most frequent indications for arthroscopy in patients with total knee arthroplasty (TKA) are soft-tissue impingement, arthrofibrosis (knee stiffness), periprosthetic infection and removal of free bodies or cement fragments. When performing a knee arthroscopy in a patient with a symptomatic TKA, look for possible free/retained bone or cement fragments, which can be anywhere in the joint. Patellar tracking should be evaluated and soft-tissue impingement under the patella or between the femoral and tibial prosthetic components should be ruled out. Current data suggest that knee arthroscopy is an effective procedure for the treatment of some patients with symptomatic TKA. The approximate rates of therapeutic success vary according to the problem in question: 85% in soft-tissue impingement; 90% in arthrofibrosis; and 55% in periprosthetic infections. More clinical studies are needed to determine which patients with symptomatic TKA can be the best candidates for knee arthroscopy.

Abstract
Patellofemoral cartilage degeneration is a potential complication of anterior cruciate ligament reconstruction (ACLR) surgery. Hypomobility of the patella in the coronal plane is often observed after ACLR. Few studies, however, have examined the relationship between cartilage degeneration in the patellofemoral joint and mobility after ACLR. The present study investigated 1) the coronal mobility of the patella after ACLR, 2) the relationship between patellar mobility and cartilage degeneration of the patellofemoral joint, and 3) the relationship between patellar mobility and knee joint function after ACLR. Forty patients who underwent medial hamstring-based ACLR participated in the study. Lateral and medial patellar displacements were assessed with a modified patellofemoral arthrometer, and the absolute values of the displacements were normalized to patient height. The International Cartilage Repair Society (ICRS) cartilage injury classification of the patellar and femoral (trochlear) surfaces, and the Lysholm Knee Scoring Scale were used to evaluate knee function. Lateral and medial patellar displacements were reduced compared with the non-operated knee at the second-look arthroscopy and bone staple extraction operation (second operation; 24.4 ± 7.9 months after ACLR, P<0.01). The ICRS grades of the patellofemoral joint (patella and trochlea) were significantly worse than those pre-ACLR. Neither lateral nor medial patellar mobility, however, were significantly correlated with the ICRS grade or the Lysholm score. Although patellar mobility at approximately 2 years after ACLR was decreased compared to the non-operated knee, small displacement of the patella was not related to cartilage degeneration or knee joint function at the time of the second operation.

Abstract
BACKGROUND Minimally invasive surgery in knee arthroplasty can reduce postoperative pain and the rehabilitation period. The goal of this study was to explore the therapeutic effect of minimally invasive arthrolysis in post-traumatic knee stiffness. METHODS From March 2002 to March 2016, a prospective investigation was performed on seventy post-traumatic knee stiffness patients treated with minimally invasive knee arthrolysis or conventional knee arthrolysis. Curative effect was evaluated according to Judet's criteria. Operative time, incision length, blood loss, the angle of intraoperative release and the final postoperative joint mobility in two groups were compared using the student's t-test. RESULTS The mean follow up time was 15.37 ± 4.93 months (ranged from 6 months to 2 years).The excellent and good rate was significantly higher in minimally invasive group (95.0%) than conventional arthrolysis group (73.33%) (P < 0.05). Minimally invasive arthrolysis group had shorter operative time (29.38 ± 4.84 vs. 86.00 ± 9.77 min), smaller incision length (6.59 ± 0.86 vs. 20.47 ± 2.91 cm), less intraoperative blood loss (93.25 ± 15.26 vs. 473.33 ± 79.58 ml) and better postoperative final joint activity (104.75 ± 17.87° vs. 90.67 ± 19.64°) compared to conventional arthrolysis group (P < 0.001). CONCLUSIONS The findings suggest that minimally invasive knee arthrolysis is a much better option for the treatment of post-traumatic knee stiffness due to its advantages such as shorter operative time, little trauma, less blood loss and better postoperative final joint activity. Further studies with a long term of follow-up are wanted.

Abstract
BACKGROUND Reduced flexion following knee arthroplasty (TKA) may compromise patient's function and outcome. The timing of manipulation under anaesthesia (MUA) has been controversial. We present our experience in a high volume practice and analyse the impact of timing. METHODS All TKA patients requiring MUA from February 1996 to June 2015 under the care of a single surgeon were analysed. MUA was offered to patients who had ≤ 75° of flexion post-op, providing that they had 30° more flexion preoperatively. To address the impact of timing from primary surgery to MUA on flexion gain we looked at 3 groups: Group I ≤ 90 days, Group II 91-180 days and Group III > 180 days. RESULTS Sixty two out of 7,423 (0.84%) underwent MUA. The MUA patients were significantly younger than the overall TKA cohort 61.2 vs 70.5 years (p = < 0.01). The median duration between arthroplasty and MUA was 3.9 months (IQR 3.4, Range 1.6-72.5 months). Overall flexion gained at 6-12 Weeks and 1 year post MUA showed significant improvements of 20.9° (p = <0.01) and 25° respectively (p = < 0.01). The flexion gain in group I (≤ 90 days) was significantly better than group III ( > 180 days) both at 6 weeks and 1 year following MUA but not better than group II (90-180 days). CONCLUSIONS MUA is an effective treatment for reduced flexion following TKA and should be the first line of management after failed physiotherapy. It can still have benefit beyond 6 months but the gains become less effective with time.

Abstract
BACKGROUND Arthrofibrosis in the suprapatellar pouch and anterior interval can develop after knee injury or surgery, resulting in anterior knee pain. These adhesions have not been biomechanically characterized. METHODS The biomechanical effects of adhesions in the suprapatellar pouch and anterior interval during simulated quadriceps muscle contraction from 0 to 90° of knee flexion were assessed. Adhesions of the suprapatellar pouch and anterior interval were hypothesized to alter the patellofemoral contact biomechanics and increase the patellofemoral contact force compared to no adhesions. RESULTS Across all flexion angles, suprapatellar adhesions increased the patellofemoral contact force compared to no adhesions by a mean of 80 N. Similarly, anterior interval adhesions increased the contact force by a mean of 36 N. Combined suprapatellar and anterior interval adhesions increased the mean patellofemoral contact force by 120 N. Suprapatellar adhesions resulted in a proximally translated patella from 0 to 60°, and anterior interval adhesions resulted in a distally translated patella at all flexion angles other than 15° (p < 0.05). CONCLUSIONS The most important finding in this study was that patellofemoral contact forces were significantly increased by simulated adhesions in the suprapatellar pouch and anterior interval. Anterior knee pain and osteoarthritis may result from an increase in patellofemoral contact force due to patellar and quadriceps tendon adhesions. For these patients, arthroscopic lysis of adhesions may be beneficial.

Abstract
A stiff total knee arthroplasty (TKA) can manifest as pain and decreased range of motion (ROM). When conservative management including physical therapy and manipulation under anesthesia fails, arthroscopic lysis of adhesions (LOA) is frequently pursued. The authors examined the efficacy of LOA for the stiff TKA. They retrospectively reviewed the records of 18 patients who underwent LOA for stiff TKA between April 2013 and June 2016 and who failed to meet 90° ROM at 6 weeks postoperatively. They recorded patient demographics, ROM prior to TKA, and incidence of manipulation under anesthesia between initial TKA and LOA as well as pre- and postoperative outcomes of ROM, pain, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores. The mean time from TKA to LOA was 117 days, with a mean follow-up of 449 days. Mean improvements in ROM flexion contracture, flexion, and arc were 6.11° (P<.05), 29.45° (P<.001), and 35.56° (P<.001), respectively. Range of motion improved for 17 of 18 patients. The WOMAC was completed by 15 of 18 patients, with a mean improvement in scores of 32.23% (P<.001); all 15 patients with available WOMAC scores improved. Pain score improved by a mean of 2.17 (P<.001), with 14 of 18 patients reporting decreased pain. Improvements in flexion contracture, flexion, ROM arc, WOMAC scores, and pain were all statistically significant (P<.05). Age, weight, body mass index, and time to LOA were found to be statistically significant predictors of outcome. Finally, pre-TKA and pre-LOA ROM parameters were found to be statistically significant predictors of post-LOA ROM outcomes. [Orthopedics. 2017; 40(6):e1062-e1068.].

Abstract
Objective: We compared gains in range of motion in patients who underwent manipulation within 12 weeks of total knee arthroplasty (TKA) and after this period. We also evaluated maintenance of the arc obtained from knee manipulation in late follow-up, along with factors associated with poorer outcomes. Method: The study was divided into two groups according to the time after TKA; the surgeries took place between January 2008 and December 2014. Results: When comparing the range of motion between early and late manipulations, the group that underwent manipulation within 12 weeks of the TKA exhibited better outcomes, but these were not statistically significant. We observed that 14.3% of cases retained the same range attained at the time of manipulation. In late evaluation after manipulation, 47.7% of the sample had a range of less than 90 degrees. The significant risk factors for recurrence of knee stiffness in the long term are poor range of motion before TKA and before manipulation, female sex, and secondary arthritis. Conclusion: Women previously diagnosed with secondary osteoarthritis and poor range of motion before TKA or manipulation are at higher risk for late stiffness.

Abstract
BACKGROUND Arthrofibrosis is a debilitating postoperative complication of total knee arthroplasty (TKA). It is one of the leading causes of hospital readmission and a predominant reason for TKA failure. The prevalence of arthrofibrosis will increase as the annual incidence of TKA in the United States rises into the millions. METHODS In a narrative review of the literature, the etiology, economic burden, treatment strategies, and future research directions of arthrofibrosis after TKA are examined. RESULTS Characterized by excessive proliferation of scar tissue during an impaired wound healing response, arthrofibrotic stiffness causes functional deficits in activities of daily living. Postoperative, supervised physiotherapy remains the first line of defense against the development of arthrofibrosis. Also, adjuncts to traditional physiotherapy such as splinting and augmented soft tissue mobilization can be beneficial. The effectiveness of rehabilitation on functional outcomes depends on the appropriate timing, intensity, and progression of the program, accounting for the patient's ability and level of pain. Invasive treatments such as manipulation under anesthesia, debridement, and revision arthroplasty improve range of motion, but can be traumatic and costly. Future studies investigating novel treatments, early diagnosis, and potential preoperative screening for risk of arthrofibrosis will help target those patients who will need additional attention and tailored rehabilitation to improve TKA outcomes. CONCLUSION Arthrofibrosis is a multi-faceted complication of TKA, and is difficult to treat without an early, tailored, comprehensive rehabilitation program. Understanding the risk factors for its development and the benefits and shortcomings of various interventions are essential to best restore mobility and function.

Abstract
BACKGROUND Intra-articular adhesion is the commonest complication that is faced by orthopedic surgeons after knee surgery. Thus, the present investigation evaluates the effect of daidzein on intra-articular adhesion in rabbits. MATERIAL AND METHODS All the rabbits were separated in to four different groups each group carries ten rabbits. Cancellous bone was exposed in each rabbit by removing cortical bone from both side of the femoral condyle. Following daidzein (2.5, 5 and 10 mg/ml) was topically applied for the duration of 10 min to the decorticated areas. Thereafter for the period of 4 week surgical limb was fixed. Effect of daidzein on intra articular adhesion was estimated by visual score through macroscopic examination, histopathology study, hydroxyproline content, fibroblast and collage density. RESULTS Data obtained in the study suggest that topical application of daidzein (5 and 10 mg/ml) loose the collagen and significantly decreases the adhesion at the decorticated areas. Moreover there were significant reduction in the fibroblast density, hydroxyproline content and optical density of collagen tissue in daidzein (5 and 10 mg/ml) treated group than control. CONCLUSION Thus present study concludes that topical application of daidzein reduces intra-articular adhesion around the knee.

Abstract
AIMS The aim of this consensus was to develop a definition of post-operative fibrosis of the knee. PATIENTS AND METHODS An international panel of experts took part in a formal consensus process composed of a discussion phase and three Delphi rounds. RESULTS Post-operative fibrosis of the knee was defined as a limited range of movement (ROM) in flexion and/or extension, that is not attributable to an osseous or prosthetic block to movement from malaligned, malpositioned or incorrectly sized components, metal hardware, ligament reconstruction, infection (septic arthritis), pain, chronic regional pain syndrome (CRPS) or other specific causes, but due to soft-tissue fibrosis that was not present pre-operatively. Limitation of movement was graded as mild, moderate or severe according to the range of flexion (90° to 100°, 70° to 89°, < 70°) or extension deficit (5° to 10°, 11° to 20°, > 20°). Recommended investigations to support the diagnosis and a strategy for its management were also agreed. CONCLUSION The development of standardised, accepted criteria for the diagnosis, classification and grading of the severity of post-operative fibrosis of the knee will facilitate the identification of patients for inclusion in clinical trials, the development of clinical guidelines, and eventually help to inform the management of this difficult condition.

Abstract
Topical application of 10-hydroxycamptothecin (HCPT) can reduce intra-articular scar adhesion after knee surgery, but the effect of HCPT on wound healing has not yet been elucidated. The study investigates the effect of the topical application of HCPT on wound healing after knee surgery in rabbits. Forty New Zealand white rabbits were divided into five groups: 2.0, 1.0, 0.5, and 0.1 mg/ml HCPT groups and control group. Approximately 10 mm × 10 mm of the cortical bone was removed from both sides of the femoral condyle, and the underneath of the cancellous bone was exposed. HCPT in various concentrations or saline was applied to the decorticated sites. Two weeks after surgery, the intra-articular adhesion was evaluated by Masson's trichrome staining. The blood vessel density and the fibroblast counting were evaluated by hematoxylin-eosin staining. The Vascular endothelial growth factor (VEGF) expression was evaluated by immunohistochemical staining and mRNA measurement. The recovery of all rabbits was stable after surgery. Topical application of HCPT could reduce intra-articular adhesion after 2 weeks. The blood vessel density, the number of fibroblast, and the level of VEGF expression in 2.0 and 1.0 mg/ml HCPT groups were lower than those of 0.5 mg/ml HCPT group, 0.1 mg/ml HCPT group, and the control group. However, there was no difference in multiple parameters between 1.0 and 2.0 mg/ml HCPT groups. Topical application of HCPT could reduce intra-articular scar adhesion in rabbits, but HCPT with concentrations above 1.0 mg/ml may affect the wound healing process by inhibiting the angiogenesis and fibroblast proliferation.

Abstract
The purpose of this study was to evaluate the effectiveness of intermittent femoral and sciatic nerve blocks combined with an in-house physiotherapy protocol for treating postoperative knee stiffness. Sixty-eight patients with postoperative knee stiffness were evaluated for passive knee flexion and extension at different time points, beginning preoperatively and continuing throughout a median 10-month follow-up after mobilization intervention. Sciatic and femoral nerve catheters were activated 1 hour prior to each physiotherapy session, which was performed twice per day and supported by a continuous passive range of motion machine. Median time from admission to catheter removal was 4 days (range, 1-8 days). Mean hospital length of stay was 7 days (range, 2-19 days). Overall mean flexion increased significantly from pretreatment (74°) to discharge (109°; P<.01). There was no significant difference in mean flexion at 6-week follow-up compared with that at discharge (108°; P=.764), but there was a significant increase in flexion at final follow-up (120°; P=.002). Overall mean knee extension lag decreased significantly from pretreatment (5°) to discharge (0.4°; P=.001). There was no significant increase in mean extension lag from discharge to final follow-up (1°; P=.2). Overall, 11 patients underwent revision surgery for persistent stiffness. This novel protocol for continuous knee mobilization under perineural blocks is a valuable alternative to knee manipulation under anesthesia for this select group of procedures. The 2 techniques produced a similar early range of motion gain, but the reported protocol resulted in less range of motion loss at follow-up and fewer possible complications.

Abstract
BACKGROUND The formation of intraarticular adhesion is a common complication after total knee arthroplasty or anterior cruciate ligament reconstruction. Previously, little research was reported regarding whether the local application of rapamycin (RAPA) could reduce intraarticular adhesion following knee surgery. In our present study, we determined the therapeutic effect of RAPA by local application on the reduction of intraarticular adhesion following knee surgery in rabbits. METHODS In this study, we built the model of knee surgery according to a previous study. The decorticated areas of the cortical bone were exposed and covered with cotton pads soaked with different concentrations of RAPA or physiological saline for 10 min. All of the rabbits were euthanized 4 weeks after the surgery. Macroscopic evaluation of the hydroxyproline content, the histological morphological analysis and collagen density and fibroblast density were used to evaluate the effect of RAPA on reducing intraarticular adhesion. RESULTS The results shown that RAPA could significantly inhibit the proliferation of fibroblasts and reduce collagen synthesis; in the rabbit model of knee surgery, there were weak scar tissues around the decorticated areas in the 0.2 mg/ml RAPA group; moderate scar tissues were found in the 0.1 mg/ml RAPA group. However, severe fibrous adhesions were found in the 0.05 mg/ml RAPA group and the control group. The hydroxyproline content and the fibroblast density in the 0.2 mg/ml and 0.1 mg/ml RAPA groups were significantly less than those of the control group. CONCLUSIONS We concluded that the local application of RAPA could reduce intraarticular adhesion after knee surgery in the rabbit model; this effect was mediated by inhibition of fibroblast proliferation and collagen synthesis, which may provide a new method for reducing intraarticular adhesion after clinical knee surgery.

Abstract
Unexplainable knee pain may follow knee replacement surgery. The popliteal tendon should be evaluated as a possible cause of lateral knee pain and dysfunction after knee arthroplasty. The tendon can snap over or impinge on lateral osteophytes or prominent femoral components and produce mechanical symptoms and pain. Ultrasound-guided injections may confirm the diagnosis and provide symptomatic relief in some patients. Those who respond well to injections and in whom conservative management ultimately fails may be offered arthroscopic release of the popliteal tendon. We present the arthroscopic technique for popliteal tendon release in a symptomatic patient whose pain resolved immediately postoperatively. We recommend the use of an anterolateral viewing portal and an accessory lateral working portal to access the posterolateral knee. There can be extensive scar tissue overlying the popliteal tendon after arthroplasty. Arthroscopic tendon transection and excision comprise a reliable procedure for popliteal tendon impingement after knee arthroplasty without compromising knee stability.

Abstract
BACKGROUND Intra-articular adhesion post knee surgery is a common and serious complication. It is a challenge problem for orthopedic surgeon. Verapamil (VP), a widely applied calcium channel blocker, has been proved to be able to prevent synthesis/secretion of extracellular matrix molecules. The object of this study was to investigate the effects of VP on the prevention of joint adhesion in post-surgery rabbits. MATERIAL/METHODS A controlled double-blinded study was conducted in 40 healthy New Zealand white rabbits divided randomly into 4 groups according to the treatment method, with 10 in each group: 1) 1 mg/ml VP treatment group; 2) 2.5 mg/ml VP treatment group; 3) 5 mg/ml VP treatment group; 4) control group. Rabbits underwent surgery through the medial parapatellar approach and both lateral sides and the medial of the femoral condyle were surgically exposed. After treatment, the surgical limbs were subjected to extra-articular knee-joint immobilization in the full flexed position employing Kirschner wires for 4 weeks. RESULTS The knee surgery was successfully performed on all rabbits. The rabbits were killed 4 weeks post-operatively. The histological evaluation, hydroxyproline content, visual score, fibroblasts density, and vimentin expressional levels were conducted to assess the effect of VP on preventing joint adhesion. CONCLUSIONS In our rabbit model of knee surgery, intra-articular application of VP was able to decrease intra-articular adhesion formation after surgery. VP could prevent rabbit intra-articular adhesion in a dose-dependent manner and the highest concentration used in the study (5 mg/ml) proved to be the most effective.

Abstract
The management of the stiff knee after total knee arthroplasty is controversial. Manipulation under anesthesia and open lysis of adhesions are techniques that can theoretically address the fibrous scar tissue, but their efficacy has been shown to be variable. We describe the technique of arthroscopic lysis of adhesions for the stiff knee after total knee arthroplasty. The advantages of this technique include minimally invasive debridement of scar tissue within defined compartments of the knee and evaluation for the presence and treatment of focal lesions (e.g., loose bodies or impinging synovial or soft tissue). The total arc of motion can be improved with a systematic arthroscopic approach.

Abstract
The aim of this study was to investigate the efficacy of topical application of colchicine in reducing intraarticular adhesion in rabbits. Thirty-six rabbits were randomly and equally divided into three groups. An approximately 10 × 10 mm2 area of cortical bone was removed from both sides of the left femoral condyle, and the cancellous bone underneath was exposed. Cotton pads soaked with different concentrations of colchicine or saline were applied to the decorticated areas for 10 minutes. The surgical limb was fixed in a flexed position for 4 weeks postoperatively. To evaluate knee intraarticular adhesion, we performed macroscopic evaluation, histological and collagen density analyses, hydroxyproline content determination, fibroblast counting and densitometric analyses. The results showed that loose collagen tissues with little or no adhesion were present around the decorticated areas in the group treated with 0.5 mg/ml colchicine. The intraarticular adhesion score, hydroxyproline content, number of fibroblasts and densitometric value in this group were also significantly lower than those in the other groups. There was moderate intraarticular adhesion in the group treated with 0.1 mg/ml colchicine. However, dense scar tissue with dense adhesions was found in the control group. In conclusion, topical application of 0.5 mg/ml colchicine may reduce knee intraarticular adhesion.

Abstract
Arthrofibrosis after total knee arthroplasty (TKA) is a potentially devastating complication, resulting in loss of motion and function and residual pain. For patients in whom aggressive physical therapy and manipulation under anesthesia fail, lysis of adhesions may be the only option to rescue the stiff TKA. The purpose of this study is to report the results of arthroscopic lysis of adhesions after failed manipulation for a stiff, cruciate-substituting TKA. This retrospective study evaluated patients who had undergone arthroscopic lysis of adhesions for arthrofibrosis after TKA between 2007 and 2011. Minimum follow-up was 12 months (average, 31 months). Average total range of motion of patients in this series was 62.3°. Average preoperative flexion contracture was 16° and average flexion was 78.6°. Statistical analysis was performed using Student's t test. Pre- to postoperative increase in range of motion was significant (P<.001) (average, 62° preoperatively to 98° postoperatively). Average preoperative extension deficit was 16°, which was reduced to 4° at final follow-up. This value was also found to be statistically significant (P<.0001). With regard to ultimate flexion attained, average preoperative flexion was 79°, which was improved to 103° at final follow-up. This improvement in flexion was statistically significant (P<.0001). Patients can reliably expect an improvement after arthroscopic lysis of adhesions for a stiff TKA using a standardized arthroscopic approach; however, patients achieved approximately half of the improvement that was obtained at the time of surgery.

Abstract
The goal of this study was to evaluate the efficacy of arthroscopic lysis of adhesions after total knee arthroplasty (TKA) in improving range of motion (ROM) and providing an improvement in knee function. The authors retrospectively examined 19 patients who underwent arthroscopic lysis of adhesions following TKA due to poor ROM. The criterion for lysis was the inability to flex to 90° at 3 months. All patients were followed for at least 2 years after lysis. Patient demographics, postoperative and follow-up ROM,number of prior surgeries, Knee Society Scores, and Western Ontario and McMaster Universities Arthritis Index (WOMAC) functional scores were collected. Average ROM increased from 75.37° preoperatively to 98.95° postoperatively. The authors found an association between preoperative knee score and change in ROM between pre-arthroscopic lysis and ROM at final follow-up (P=.0188). When the authors examined the relationship between patient body mass index (BMI) and change in ROM,they found that patients with a BMI higher than 30 kg/m2 had a change of 26.44° compared with patients with a BMI lower than 30 kg/m2, who had a change of only 8.75°. A strong association was found between patient height and change in ROM and final ROM achieved (P=.0062 and .0032, respectively). The authors report a successful outcome among study patients. Furthermore, they found an association between patient height, BMI, and preoperative knee score and the improvement achieved after arthroscopic lysis of adhesions following TKA. The current study's results are comparable with those of published results. The authors recommend arthroscopic lysis of adhesions as a treatment option for stiff knees after TKA that fails after at least 3 months of nonoperative treatment.

Abstract
Treatment options for arthrofibrosis following total knee arthroplasty include manipulation under anesthesia, open or arthroscopic arthrolysis, and revision surgery to correct identifiable problems. We propose preoperative low-dose irradiation and Constrained Condylar or Rotating-hinge revision for severe, idiopathic arthrofibrosis. Irradiation may decrease fibro-osseous proliferation while constrained implants allow femoral shortening and release of contracted collateral ligaments. Fourteen patients underwent fifteen procedures for a mean overall motion of 46° and flexion contracture of 30°. One patient had worsening range of motion while thirteen patients had 57° mean gain in range of motion (range 5°-90°). Flexion contractures decreased by a mean of 28°. There were no significant complications at a mean follow up of 34 months (range 24 to 74 months).

Abstract
Intraoperative range of motion (ROM) assessment can be challenging during total knee arthroplasty (TKA) surgery. As computer assisted surgery is costly and not readily available to many surgeons, we have developed a simple, cost-effective intraoperative device to precisely measure knee flexion and extension. A simple knee goniometer system was constructed consisting of a digital level mounted to a base that rigidly attaches two standard needles. The needles are pushed through the overlying soft tissue of the distal femur. The device is then applied to the proximal tibia, where an angle measurement of the knee is registered. A validation study for this device was conducted on two pairs of intact cadaveric lower limbs at 0 deg, 10 deg, 15 deg, 20 deg, 25 deg, and 30 deg. Two orthopedic surgeons experienced with the system performed three measurements at each angle. Systematic error, defined as the goniometer reading at 0 deg flexion anatomically as determined by the navigation system, ranged from −9.1 deg to 3.0 deg, consistent for each operator on every case. Measurement error, defined as the variability in repeated, fixed angle measurements made with the goniometer, was 1.5 ± 1.0 deg across all surgeons, cases, and prescribed flexion angles. For both surgeons and all imposed flexion angles, measurement errors were below the 4 deg clinical threshold. The simple knee goniometer system generated accurate, repeatable measures of changes in flexion angle intraoperatively with measurement error comparable to errors obtained using the commercial navigation system (1 deg–2 deg). However, the knee goniometer is less complex, less time intensive, and less costly than currently available computer assistive devices. Taken together, our results are very promising for the continued development of this device.

Abstract
AIM The aim of the study was to systematically evaluate the outcome of four main modalities of treatment for arthrofibrosis that develops subsequent to a total knee arthroplasty (TKA), namely manipulation under anesthesia (MUA), arthroscopic debridement, open surgical release and revision TKA. MATERIALS AND METHODS A computerised search was conducted for relevant studies published from 1975 onwards in all the major databases and various search engines. A total of twenty-five studies were selected, representing a total of 798 patients. Studies that passed the inclusion criteria were then subjected to quality assessment using the Newcastle-Ottawa Scale. On assessment, the 25 studies scored a total of 77 stars out of a possible 125. Two studies were prospective in design, while the remaining case series were retrospective in nature. The primary outcome measures assessed were increase in range of movement (ROM) and the Knee Society Score (KSS) at final follow-up. RESULTS Our results showed that manipulation under anesthesia (MUA) had a mean increase in ROM of 38.4°, arthroscopic release had a mean increase of 36.2°, open surgical release had a mean increase of 43.4° and revision TKA had a mean increase of 24.7°. No significant differences were found in the KSS of the four treatment modalities. Our analysis suggests that open surgical release would be the most beneficial option for patients who are fit to undergo secondary surgery if their lifestyle requires a higher ROM for activities of daily living. However, there were methodological limitations as majority of the papers were case series, which decreased the quality of the evidence available.

Abstract
INTRODUCTION Stiffness following total knee arthroplasty (TKA) is a disabling problem resulting in pain and reduced function. OBJECTIVE The aim of our study was to evaluate the natural course of fixed flexion deformity (FFD ) following primary total knee arthroplasty. METHODS Prospective review of 1626 patients undergoing primary TKA from 2001 to 2006 with a minimum of 4 year follow up. Demographic data included post-operative range of motion; type of prosthesis used, treatment modalities for stiffness and the final range of motion were recorded. FFD was defined as class 1(5-15 degrees) and Class 2 (> 15 degrees). Patients with a pre-operative FFD of >15, infection, stiffness treated with manipulation or revision surgery were excluded from the study. RESULTS Of the 1626 patients evaluated, 170 (10.5%) presented with a FFD. 18 patients were excluded from the study and 16 were lost to follow up. 124 (91.2%) were class 1 and 12 (8.8%) were class 2. FFD improved from a mean of 8.8 degrees to 0.4 degrees (p<0.0001) in 11.4 months. In 94.1% patients the FFD completely resolved (i.e. < 5 degrees) at a mean of 10.8 months (p<0.0001). In the remaining 5.9% of patients, FFD improved from a mean of 16.4 to 6.9 degrees at a mean follow up of 21.5 months (p<0.0001). CONCLUSION A gradual improvement in the FFD can be expected up to 2 years and a small residual flexion contracture does not cause functional deficit.

Abstract
Arthrofibrosis after total knee arthroplasty (TKA) is difficult to treat, as its aetiology remains unclear. In a previous study, we established a connection between the BMP-2 concentration in the synovial fluid and arthrofibrosis after TKA. The hypothesis of the present study was, therefore, that the limited range of motion in arthrofibrosis is caused by BMP-2 induced heterotopic ossifications, the quantity of which is dependent on the BMP-2 concentration in the synovial fluid. Eight patients with arthrofibrosis after TKA were included. The concentration of BMP-2 in the synovial fluid from each patient was determined by ELISA. Radiologically, digital radiographs were evaluated and the grey scale values were determined as a measure of the tissue density of defined areas. Apart from air, cutis, subcutis and muscle, the soft-tissue density in the area of the capsule of the suprapatellar pouch was determined. The connection between the BMP-2 concentration and the soft-tissue density was then investigated. The average BMP-2 concentration in the synovial fluid was 24.3 ± 6.9 pg/ml. The density of the anterior knee capsule was on average 136 ± 35 grey scale values. A linear correlation was shown between the BMP-2 concentration in the synovial fluid and the radiological density of the anterior joint capsule (R=0.84, p = 0.009). We were able to show that there is a connection between BMP-2 concentration and soft-tissue density in arthrofibrosis after TKA. This opens up the possibility of conducting a prophylaxis against arthrofibrosis in risk patients by influencing the BMP-2 pathway.

Abstract
We sought to compare the preventive effects of mitomycin-C(MMC) and chitosan on intraarticular adhesion after knee surgery in rabbits. For this purpose, 48 New-Zealand rabbits were randomly and equally divided into MMC, chitosan, and control groups. Approximately 10 × 10 mm(2) of the cortical bone was removed from both sides of left femoral condyle and the cancellous bone underneath was exposed. The decorticated areas were topically treated with MMC and chitosan while control group was treated with physiological saline. The lower left limb was fixed in flexed position with Kirschner-wire for 4 weeks postoperatively. After 4 weeks, gross and histopathological examination, biochemical analysis, and fibroblast counts were performed on knee intraarticular adhesion in each group. The data show mild membrane-like fibrous intraarticular adhesion, presented in loose, in MMC group. There was moderate intraarticular adhesion in chitosan group while in controls; there was large-size compact fibrous tissue adhesion. Hydroxyproline contents and fibroblast quantity of MMC and chitosan groups were lower (P < 0.05) than that of control group. We, therefore, concluded that MMC and chitosan could prevent intraarticular adhesion of the knee in rabbits by inhibiting fibroblast proliferation and reducing collagenous fiber formation while MMC had a better preventive effect than that of chitosan.

Abstract
BACKGROUND Arthrofibrosis is an uncommon but potentially debilitating complication following total knee replacement which can result in chronic pain and poor recovery of range of motion. The treatment of this condition remains difficult and controversial. QUESTIONS/AIMS OF STUDY: We reviewed our results of arthroscopic arthrolysis of arthrofibrosis of the knee after total knee replacement to assess the potential for this technique to improve range of motion and provide improvement in knee function and pain as measured by the Knee Society Score (KSS). METHODS Eight patients were treated for arthrofibrosis after total knee replacement with arthroscopic management. The patients included five females and three males. The average age was 67.4 years. Initial rehabilitation efforts, which included manipulation under anesthesia, had failed. Arthroscopic arthrolysis was performed to release fibrous bands in the suprapatellar pouch and to reestablish the medial and lateral gutters. Lateral release of the patellar retinaculum was performed. Intensive physiotherapy and continuous passive motion began immediately post-operatively. The average follow-up was 37.4 months. The KSS was used for assessment of pain and function before arthroscopy and at the latest follow-up. RESULTS Six of the eight patients experienced improvement in the KSS. The average functional score showed improvement from 68 points pre-operatively to 86 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. CONCLUSIONS Arthroscopic management can be beneficial for patients suffering from arthrofibrosis following total knee replacement. Pain and KSS clinical scores can markedly improve.

Abstract
Diminished range of motion (ROM) of the knee joint after total knee arthroplasty (TKA) is thought to be related to reduced patellar mobility. This has not been confirmed clinically due to a lack of quantitative methods adequate for measuring patellar mobility. We investigated the relationship between patellar mobility by a reported quantitative method and knee joint ROM after TKA. Forty-nine patients [osteoarthritis--OA: 29 knees; rheumatoid arthritis--RA: 20 knees] were examined after TKA. Respective medial and lateral patellar mobility was measured 1 and 6 months postoperatively using a patellofemoral arthrometer (PFA). Knee joint ROM was also measured in each of those 2 sessions. Although the flexion and extension of the knee joints improved significantly from 1 to 6 months after TKA, the medial and lateral patellar displacements (LPDs) failed to improve during that same period. Moreover, only the changes in knee flexion and medial patellar displacement (MPD) between the two sessions were positively correlated (r = 0.31, p < 0.05). However, our findings demonstrated that medial and lateral patellar mobility had no sufficient longitudinal relationship with knee ROM after TKA.

[PMID: 20087698 PMCID: PMC2835585 DOI: 10.1007/s11999-010-1230-y] [Citation(s) in RCA: 102] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2009] [Accepted: 01/05/2010] [Indexed: 01/31/2023]
Abstract
BACKGROUND Multiple modalities have been used to treat the stiff TKA, including manipulation under anesthesia (MUA), arthroscopy, and open arthrolysis. QUESTIONS/PURPOSES We reviewed the literature to address three questions: (1) How many degrees of ROM will a stiff TKA gain after MUA, arthroscopy, and open arthrolysis? (2) Does the timing of each procedure influence this gain in ROM? (3) What is the number of clinically important complications for each procedure? METHODS We performed a PubMed search of English language articles from 1966 to 2008 and identified 20 articles, mostly Level IV studies. RESULTS For patients who have arthrofibrosis after TKA, the gains in ROM after MUA and arthroscopy (with or without MUA) are similar. Open arthrolysis seems to have inferior gains in ROM. MUA is more successful in increasing ROM when performed early but still may be effective when performed late. Arthroscopy combined with MUA still is useful 1 year after the index TKA. The numbers of clinically important complications after MUA and arthroscopy (with or without MUA) are similar. CONCLUSIONS Stiffness after TKA is a common problem that can be improved with MUA and/or arthroscopic lysis of adhesions with few complications. The low quality of available literature makes it difficult to develop treatment protocols. LEVEL OF EVIDENCE Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Arbuthnot JE, Brink RB. Arthroscopic arthrolysis for the treatment of stiffness after total knee replacement gives moderate improvements in range of motion and functional knee scores. Knee Surg Sports Traumatol Arthrosc 2010; 18:346-51. [PMID: 19649615 DOI: 10.1007/s00167-009-0878-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2009] [Accepted: 07/03/2009] [Indexed: 10/20/2022]
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
Fibrosis represents a major global disease burden, yet a potent antifibrotic compound is still not in sight. Part of the explanation for this situation is the difficulties that both academic laboratories and research and development departments in the pharmaceutical industry have been facing in re-enacting the fibrotic process in vitro for screening procedures prior to animal testing. Effective in vitro characterization of antifibrotic compounds has been hampered by cell culture settings that are lacking crucial cofactors or are not holistic representations of the biosynthetic and depositional pathway leading to the formation of an insoluble pericellular collagen matrix. In order to appreciate the task which in vitro screening of antifibrotics is up against, we will first review the fibrotic process by categorizing it into events that are upstream of collagen biosynthesis and the actual biosynthetic and depositional cascade of collagen I. We point out oversights such as the omission of vitamin C, a vital cofactor for the production of stable procollagen molecules, as well as the little known in vitro tardy procollagen processing by collagen C-proteinase/BMP-1, another reason for minimal collagen deposition in cell culture. We review current methods of cell culture and collagen quantitation vis-à-vis the high content options and requirements for normalization against cell number for meaningful data retrieval. Only when collagen has formed a fibrillar matrix that becomes cross-linked, invested with ligands, and can be remodelled and resorbed, the complete picture of fibrogenesis can be reflected in vitro. We show here how this can be achieved. A well thought-out in vitro fibrogenesis system represents the missing link between brute force chemical library screens and rational animal experimentation, thus providing both cost-effectiveness and streamlined procedures towards the development of better antifibrotic drugs.

Abstract
Stiffness is a relatively uncommon complication after total knee arthroplasty. It has been defined as a painful limitation in the range of movement (ROM). Its pathogenesis is still unclear even if some risk factors have been identified. Patient-related conditions may be difficult to treat. Preoperative ROM is the most important risk factor, but an association with diabetes, reflex sympathetic dystrophy, and general pathologies such as juvenile rheumatoid arthritis and ankylosing spondylitis has been demonstrated. Moreover, previous surgery may be an additional cause of an ROM limitation. Postoperative factors include infections, arthrofibrosis, heterotrophic ossifications, and incorrect rehabilitation protocol. Infections represent a challenging problem for the orthopaedic surgeon, and treatment may require long periods of antibiotics administration. However, it is widely accepted that an aggressive rehabilitation protocol is mandatory for a proper ROM recovery and to avoid the onset of arthrofibrosis and heterotrophic ossifications. Finally, surgery-related factors represent the most common cause of stiffness; they include errors in soft-tissue balancing, component malpositioning, and incorrect component sizing. Although closed manipulation, arthroscopic and open arthrolysis have been proposed, they may lead to unpredictable results and incomplete ROM recovery. Revision surgery must be proposed in the case of well-documented surgical errors. These operations are technically demanding and may be associated with high risk of complications; therefore they should be accurately planned and properly performed.

Abstract
According to literature, knee arthroscopy is a minimal invasive surgery performed for minor surgical trauma, reduced morbidity and shortens the hospitalization period. Therefore, this type of surgery before total knee arthroplasty (TKA) could be considered a minor procedure with minimum postoperative complication. A retrospective and cohort series of 1,474 primary TKA was performed with re-assessment after a minimum follow-up period of 2 years: 1,119 primary TKA had no previous surgery (group A) and 60 primary TKA had arthroscopic debridement (group B). All the patients underwent a clinical and radiological evaluation as well as IKS scores. Statistical analysis of postoperative complications revealed that group B had a higher postoperative complication rate (P < 0.01). In this group, 30% of local complications were re-operated and 8.3% of these cases underwent revision TKA (P < 0.01). The mean interval between arthroscopy and primary TKA was 53 months. However, statistical analysis did not reveal a direct correlation between arthroscopy/primary TKA interval and postoperative complications/failures (P = 0.55). The Kaplan-Meier survival curves showed a survival rate of 98.1 and 86.8% at 10 years follow-up for groups A and B, respectively. Our data allow us to conclude that previous knee arthroscopy should be considered a factor related to postoperative primary TKA outcomes as demonstrated by the higher rate of postoperative complications and failures (P < 0.001) as well as a worse survival curve than group A.
