Abstract
INTRODUCTION Patients with total knee arthroplasty occasionally develop postoperative abnormalities such as posttraumatic knee stiffness and arthrofibrosis, which may affect activities of daily living. However, there are no clear assessment methods or interventions for knee stiffness. Musculoskeletal ultrasound imaging enables real-time evaluation of mobility and flexibility of tissues. The purpose of this case report was to describe the use of musculoskeletal ultrasound imaging for evaluating the optimal location and methods of passive manipulation. CASE DESCRIPTION The patient was an 82-year-old woman who had undergone total knee arthroplasty. She was unable to climb stairs due to limited knee flexion. Based on the results of musculoskeletal ultrasound imaging assessment, we hypothesized that the knee flexion limitation was caused by decreased sliding movement of the suprapatellar pouch. Hence, we performed passive manipulation on the tissue with decreased sliding under musculoskeletal ultrasound guidance. OUTCOMES The patient's knee flexion angle increased from 90° to 110° within 1 week of intervention, and her gait speed improved from 16.48 to 13.2 s per 10 m. Furthermore, after the intervention, she was able to climb 10 steps using a handrail. DISCUSSION Ultrasound imaging is important because it allows the examination of tissues with mobility changes such as in arthrofibrosis. Our work highlights the use of musculoskeletal ultrasound imaging for identifying the target region for therapy and for providing guidance during passive manipulation.

Abstract
OBJECTIVES Although nonsurgical and surgical management of knee arthrofibrosis has been reported in the literature, there is little information on the effect of procedural treatment modalities of refractory arthrofibrosis on clinical outcomes. The purpose of this case report is to describe the intervention of refractory knee arthrofibrosis after anterior cruciate ligament reconstruction and investigate long-term clinical outcomes after procedural intervention. METHODS A 27-year-old male presented with decreased range of motion (ROM), patellar mobility, strength, and knee joint function following anterior cruciate ligament reconstruction of his left knee. After failed conservative management, the patient underwent manipulation under anesthesia (MUA) to release scar tissue. Following MUA, the emphasis of comprehensive physiotherapy was on decreasing inflammation, relieving pain, and maintaining patellar mobility while increasing knee joint ROM and strength. Knee ROM, patellofemoral motion, gait, and quadriceps recruitment were measured 3, 6, 12, and 24 months after MUA. RESULTS At 2-year follow-up after MUA, the patient continued to present with decreased ROM and quadriceps strength compared to the contralateral knee, but had returned to a running program and reported knee joint dysfunction no longer interfered with his daily activities. CONCLUSIONS This case report demonstrates signs and symptoms that could indicate knee arthrofibrosis and introduces procedural intervention for refractory arthrofibrosis after anterior cruciate ligament reconstruction.

Abstract
Objective Patellofemoral kinematics and contact mechanics are important measurements for the assessment of patellofemoral joint (PFJ) problems. Simultaneously measuring PFJ contact pressures and kinematics is a challenging task. The purpose of this study was to simultaneously measure the kinematics and mean/peak contact pressures in the PFJs of cadaveric knees. Methods This was a comparative study performed on fresh cadaveric knees. The kinematic data was acquired for nine cadaveric knees using an optical tracking system. Data about the contact pressure and contact area in the PFJ was obtained at knee flexion angles of 0°, 30°, 60°, 90°, and 120° using a pressure sensor. Intraclass correlation coefficients (ICCs) and minimal detectable differences (MDDs) of six degrees of freedom (6 DOF) in the PFJs were calculated. ICCs and the MDDs of contact pressure, peak pressure, and contact area in the PFJs were also analyzed. We also compared the kinematics of the cadaveric knees before and after the insertion of the pressure sensor. Results All ICC values of 6 DOF in the PFJs were found to be greater than or equal to 0.924. Regarding medial–lateral rotation, the patellar showed a simplified movement pattern that demonstrated progressive lateral rotation of 4.8° ± 3.4° at 120° of knee flexion. While for patellar tilting, the patella showed medial tilting that peaked at 7.2 ± 2.5° at 30° of knee flexion. Whereas no significant differences in PFJ kinematics were found between with and without the placement of the pressure sensor at all knee flexions (P > 0.05). Most of the ICC values for contact pressure, peak contact pressure, and contact area ranged from 0.8 to 0.9. The MDDs for rotational displacement were 0.9° and 0.6 mm for translational displacement. No statistical differences in patellar kinematics were found before and after the insertion of the pressure sensor. Conclusions The setup in the present study enables researchers to simultaneously and synchronously collect real‐time PFJ kinematics and tibiofemoral joint (TFJ) biomechanical kinematic data with high reliability. The low MDDs enabled the researchers to obtain an accurate interpretation of the kinematic and contact mechanics measurement using the experimental setting used in the present study.

Abstract
OBJECTIVE The purpose of this study is to evaluate the difference of patellofemoral kinematics between weightbearing and non-weightbearing conditions in the arthrofibrotic knee after anterior cruciate ligament (ACL) reconstruction. METHODS Twenty patients with arthrofibrosis after ACL reconstruction were included in the study. Computed tomography scanner and dual fluoroscopic imaging techniques were used to compare patellofemoral kinematics of the affected knee between weightbearing knee flexion and non-weightbearing knee flexion. In both positions, patellofemoral kinematics in six degrees-of-freedom (6 DOF) were measured respectively. RESULTS The patellar lateral tilt angle (p = 0.007) and medial patellar translation (p = 0.043) under the weightbearing condition were significantly decreased compared to the non-weightbearing task between 5° and 15° of knee flexion. The lateral patellar translation during a non-weightbearing task was significantly decreased between 60° and 75° of knee flexion (p = 0.005), and the inferior patellar translation under the weightbearing condition was significantly increased between 45° and 75° of knee flexion (p = 0.040). CONCLUSION These results indicate that patellofemoral kinematics during non-weightbearing positions do not sufficiently represent the patellar tracking during functional weightbearing activities. Our findings of this study establish the clinical relevance and significance of assessing the patellofemoral kinematics under the weightbearing condition when evaluating patients with arthrofibrosis after ACL reconstruction.

Abstract
Multiligament knee injuries (MLKIs) are debilitating injuries that increasingly occur in young athletes. Return to sport (RTS) has historically been considered unlikely due to the severity of these injuries. Reporting in the literature regarding objective outcomes following MLKI, including RTS, is lacking, as are clear protocols for both rehabilitation progressions and RTS testing. RTS following MLKI is a complex process that requires an extended recovery duration compared to other surgery types. Progressions through postoperative rehabilitation and RTS should be thoughtful, gradual, and criterion based. After effective anatomic reconstruction to restore joint stability, objective measures of recovery including range of motion, strength, movement quality, power, and overall conditioning guide decision-making throughout the recovery process. It is important to frame the recovery process of the athlete in the context of the severity of their injury, as it is typically slower and less linear. Improved reporting on objective outcomes will enhance our understanding of recovery expectations within this population by highlighting persistent deficits that may interfere with a full recovery, including RTS.

Abstract
Context: Arthrofibrosis after anterior cruciate ligament (ACL) reconstruction can be detrimental to the knee joint function and patient outcomes. However, the effects of arthrofibrosis on the in vivo tibiofemoral and patellofemoral joint kinematics after ACL reconstruction remain unclear. Objective: The objective of this study was to quantify the in vivo knee kinematics during a dynamic lunge task in the knee with arthrofibrosis after ACL reconstruction. Methods: Eleven patients with arthrofibrosis in one knee after ACL reconstruction participated in this study. Computed tomography and dual fluoroscopic imaging were used to evaluate in vivo kinematics of affected and contralateral knees during a lunge task. Differences in 6 degrees of freedom tibiofemoral kinematics and patellar tracking between limbs were assessed via repeated-measures analysis of variance. Results: Internal tibial rotation (5.2° vs 7.5°, respectively; P < .001) and inferior patellar shift (24.6 mm vs 28.9 mm, respectively; P < .001) were significantly lower in the arthrofibrotic knee compared with the contralateral knee from 15° to 75° of knee flexion. The patella in the arthrofibrotic knee significantly less flexed by 9.1° (P = .009) throughout the measured ROM and less laterally tilted by 3° (P = .017) compared with the contralateral knee from 30° to 75° of knee flexion. Conclusions: A significant superior shift and medial tilt of the patella were found in the affected knee compared with those in the contralateral knee during the dynamic lunge. Decreased internal tibial rotation and patellar flexion were found in knees with arthrofibrosis following ACL reconstruction; whether these kinematic changes are caused by arthrofibrosis need further investigation.

Abstract
Background Knowledge of tibiofemoral and patellofemoral joint kinematics is important for understanding gender-related dimorphism in developing knee arthrofibrosis and advancement of related treatments. The objective of our study was to investigate gender differences existing in tibiofemoral kinematics and patellar tracking in patients with arthrofibrosis after anterior cruciate ligament (ACL) reconstruction during weight-bearing knee flexion. Methods The tibiofemoral and patellofemoral joint kinematics were measured in 30 patients (15 male and 15 female) with arthrofibrosis after ACL reconstruction during a lunge task, using computed tomography and dual fluoroscopic imaging system. These data were analyzed for gender differences. Results The range of tibial rotation, patellar inferior shift, tilt, and flexion were significantly decreased in the affected knee compared to the contralateral knee from 15° to 75° of knee flexion (P ≤ 0.04). Statistically significant difference was detected for medial tibial translation between male and female patients at 60° (P = 0.04) and 75° of knee flexion (P = 0.02). The tibial rotation was significantly decreased at 60° (P = 0.03) and 75° of knee flexion (P < 0.01) in females. The inferior patellar shift in females was significantly lower than that in males at 15° (P = 0.04) and 30° of knee flexion (P = 0.01). The patellar tilt was significantly lower at 60° (P = 0.02) and 75° of knee flexion (P < 0.01) in females compared to males. Conclusions The results indicated a significant effect of gender on knee kinematics in patients with arthrofibrosis after ACL reconstruction during weight-bearing knee flexion. These gender differences in tibiofemoral kinematics and patellar tracking may warrant further investigations to determine implications for making gender-specific surgical treatments and rehabilitation programs.

Abstract
Aim: Pathologic hyperplasia of fibroblast is responsible for the progression of intraarticular fibrosis. Laminin α4 (LAMA4), a subunit of laminin macromolecule family, was found to be overexpressed in various fibrotic tissues. However, the role of LAMA4 in knee arthrofibrosis remains elusive. Therefore, the aim of this study was to investigate the effect and mechanism of LAMA4 on fibroblast proliferation and migration. Materials and methods: Following knee surgery, LAMA4 expression was detected in intraarticular fibrous tissues in rabbits at week 2 and week 4, respectively. In lentivirus-mediated LAMA4-overexpressed fibroblasts, cellular proliferation was assessed by EdU labeling and cell cycle analysis, cellular migration was evaluated using Transwell assay, and the expressions of key components in Shh/Gli1 signaling were detected by qRT-PCR, western blot and immunofluorescence analysis. Additionally, canonical Shh cascade was further blocked in LAMA4-overexpressed fibroblasts by cyclopamine, and the changes in cellular proliferation and migration were investigated. Results: LAMA4 expression was positively correlated with the severity of knee arthrofibrosis. Functional studies demonstrated that LAMA4 overexpression facilitated proliferation, cell cycle progression and migration in fibroblasts. Mechanically, LAMA4 activated the canonical Shh/Gli1 signaling and promoted the nuclear translocation of Gli1 to upregulate expression of genes associated with cellular proliferation and migration. Intriguingly, blockage of Shh/Gli1 signaling with cyclopamine reversed the promoting effects of LAMA4 on proliferation and migration of fibroblasts. Conclusions: LAMA4 positively regulated cellular proliferation and migration in fibroblasts via activating the Shh/Gli1 signaling. LAMA4/Shh/Gli1 signaling axis might be a potential therapeutic target for the prevention of surgery-induced intraarticular fibrosis.

Knee Extensor Mechanism Strength and Its Relationship to Patellofemoral Kinematics in Individuals With Arthrofibrosis Within 6 Months After Anterior Cruciate Ligament Reconstruction. J Sport Rehabil 2021; 30:1138-1143. [PMID: 34111841 DOI: 10.1123/jsr.2020-0468] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 04/05/2021] [Accepted: 04/25/2021] [Indexed: 11/18/2022]
Abstract
CONTEXT Performance in strength and assessment of patellar tracking is important for patients with arthrofibrosis after anterior cruciate ligament (ACL) reconstruction. OBJECTIVE The study was to examine the difference of patellofemoral kinematics between the affected and the contralateral limb and to evaluate the relationship between knee extensor strength and patellofemoral kinematics in patients with arthrofibrosis after ACL reconstruction. DESIGN Cohort study (diagnosis); level of evidence, 3. SETTING Laboratory. PATIENTS A prospective cohort of 20 patients with arthrofibrosis after ACL reconstruction was recruited. INTERVENTIONS A total of 20 patients who underwent arthroscopic reconstruction of the double-bundle ACL with a hamstring tendon autograft received standardized patellofemoral kinematics testing and knee extensor strength testing within 6 months after primary ACL reconstruction. Computed tomography and dual fluoroscopic imaging were used to evaluate in vivo patellofemoral kinematics of affected and contralateral knees during a lunge task. Knee extensor mechanism strength was measured using a handheld dynamometer. MAIN OUTCOME MEASURES A limb symmetry index of knee strength and patellar mobility was calculated and satisfactory performance defined as ≥90%. RESULTS There was a statistically significant decrease in the range of patellar inferior shift (P = .020; d = 0.81), flexion (P = .026; d = 0.95), lateral tilt (P = .001; d = 1.04), and lateral rotation (P < .001; d = 0.89) in the affected knee compared with the contralateral knee from 15° to 75° of knee flexion. There was a strong positive linear correlation between knee extensor strength and patellar inferior shift (r = .747; P = .008). A knee extensor strength limb symmetry index <90% was 89% sensitive and 9% specific for limited patellar inferior shift. CONCLUSIONS Patients with arthrofibrosis after ACL reconstruction presented decreased patellar mobility in the arthrofibrotic knee compared with the contralateral knee. The strong correlation between knee extensor strength and patellar inferior shift of the arthrofibrotic knee demonstrates the importance of knee extensor strength in the diagnosis and treatment of patients with knee arthrofibrosis. The knee extensor mechanism strength has high sensitivity but low specificity in identifying a decrease in patellar inferior shift in patients with arthrofibrosis after ACL reconstruction.

Abstract
BACKGROUND The occurrence of Patellofemoral Pain Syndrome (PFPS) is often found in daily medical care. Rehabilitation is usually applied with good results. However, patients often do not respond to standard rehabilitation, suggesting there may be some undetected factors that standard treatments cannot address. It is known that post-traumatic adhesive capsulitis in the knee often shows symptoms similar to those of PFPS, but idiopathic adhesive capsulitis (IAC) has seldom been mentioned as a possible cause of PFPS. Adhesive capsulitis in the shoulder joint causes frozen shoulder (FS), and hydraulic distension (HD) is often applied to FS effectively. PURPOSE The purpose of this study was to investigate and report on the clinical application of HD to treat PFPS non-responsive to rehabilitation treatment. PATIENTS AND METHODS HD was applied to 72 knees that had resisted regular conservative treatments for PFPS. Follow-up data (e.g. visual analogue scale) was collected immediately after HD, and at periods of 1, 3 and 6 months later. RESULTS Of the 72 patients, 64 patients obtained pain relief after HD. Pain was relieved for at least 6 months for 33 of the 64 patients. No benefit was received for 8 patients. CONCLUSIONS HD could be an additional conservative option for some PFPS that resisted rehabilitation. Assuming that the mechanisms of action for HD in the knee are the same as those in FS, there is evidence to suggest that IAC might play a role in the development of PFPS for some patients.

Abstract
Postoperative scarring is one of the complications after arthroscopic knee surgery, which is usually treated with manual therapy or arthroscopic debridement. The incidence of symptomatic scarring requiring surgery within six months postoperatively has been reported to be approximately 0.06-6.00%. We treated a patient after arthroscopic surgery with a new "ultrasound-guided hydrorelease" procedure and we describe it. A 50-year-old woman with a history of arthroscopic anterior cruciate ligament reconstruction of the right knee presented to our clinic 10 months ago with a complaint of right anterior knee pain. Ultrasound imaging showed an infrapatellar fat pad (IPFP) scarring and sliding defects. The pre-treatment Kujala scale was 62 points and the visual analogue scale was 72. The inferolateral side of the patella was palpated to identify the scarring after arthroscopy at the IPFP area. An ultrasound probe was applied vertically to identify the site of adhesion of interest. Ultrasound-guided hydrorelease was performed using 7.0mL saline injected by needle (22G, 60mm) directed at the site with hypoechoic changes in the IPFP. After the procedure, the normalization of the IPFP sliding was confirmed by an ultrasound image. Four weeks after this procedure, the patient improved, with a Kujala scale of 82 points and a visual analogue scale of 28. The most important finding from this patient's course is that her chief complaint of anterior knee pain improved by ultrasound-guided hydrorelease into the IPFP scarring after arthroscopic knee surgery. The procedure should be considered as a treatment for scarring after arthroscopic knee surgery.

Abstract
Postoperative scarring is a known complication after arthroscopic anterior ligament reconstruction of the knee. The anterior interval of the knee has been previously identified as a common location for anterior scar formation. The anterior interval is defined as the space between the infrapatellar fat pad and the anterior border of the tibia. Patients with anterior interval scarring often present with lack of terminal knee extension, anterior knee pain, decreased patellar mobility, and quadriceps atrophy. The goal of this paper is to describe the technique for anterior interval release of the knee.
