Quadriceps tendon ruptures are a rare but debilitating injury resulting in loss of knee extension necessitating surgical intervention. Currently, multiple different surgical techniques and rehabilitation programs are utilized by surgeons. Researchers have been unable to determine the best surgical technique with respect to function and complication rate; certain techniques are more cost-effective than others. Early vs. late motion rehabilitation programs are utilized; recent evidence suggests that less aggressive initial rehabilitation may lead to decreased extensor lag and fewer additional surgeries. The goal of our study is to determine the treatment practices of orthopaedic surgeons across Canada. Our study was completed anonymously via . SurveyMonkey.com. (Palo Alto, California). Based on current literature, a 26-question survey was distributed. E-mail invitations were be sent to all members of the Canadian Orthopaedic Association. Participation is voluntary. Currently, 104 surveys have been completed. 78% of respondents utilize transosseous drill holes, 13% utilize suture anchors and 9% utilize a combined surgical technique. The majority of surgeons begin range of motion (ROM) at 2 weeks (42%) or 6 weeks (24%); ROM is then commonly progressed in a step-wise fashion at 2-week intervals (58%). Approximately half of respondents have performed revision surgery for quadriceps re-rupture. Surgical management of quadriceps tendon ruptures is fairly consistent amongst Canadian orthopaedic surgeons. However, wide variation exists regarding rehabilitation, favoring early initiation and progression of ROM despite some evidence recommending a longer period of immobilization

Abstract. Source of Study: London, United Kingdom. This intervention study was conducted to assess two developing protocols for quadriceps and hamstring rehabilitation: Blood Flow Restriction (BFR) and Neuromuscular Electrical Stimulation Training (NMES). BFR involves the application of an external compression cuff to the proximal thigh. In NMES training a portable electrical stimulation unit is connected to the limb via 4 electrodes. In both training modalities, following device application, a standardised set of exercises were performed by all participants. BFR and NMES have been developed to assist with rehabilitation following lower limb trauma and surgery. They offer an alternative for individuals who are unable to tolerate the high mechanical stresses associated with traditional rehabilitation programmes. The use of BFR and NMES in this study was compared across a total of 20 participants. Following allocation into one of the training programmes, the individuals completed training programmes across a 4-week period. Post-intervention outcomes were assessed using Surface Electromyography (EMG) which recorded EMG amplitude values for the following muscles: Vastus Medialis, Vastus Lateralis, Rectus Femoris and Semitendinosus. Increased Semitendinosus muscle activation was observed post intervention in both BFR and NMES training groups. Statistically significant differences between the two groups was not identified. Larger scale randomised-controlled trials are recommended to further assess for possible treatment effects in these promising training modalities

Background:. The aim of this study was to investigate the outcome after ACL reconstruction between a group of patients receiving a standardized supervised physiotherapy guided rehabilitation program and a group of patients who followed an un-supervised, home-based rehabilitation program. Methods:. 40 patients with isolated anterior cruciate ligament injuries were allocated to either a supervised physiotherapy intervention group or home-based exercise group. Patients were investigated by an independent examiner pre-operative, 3, 6, 9 and 12 months post-surgery using the following outcome measures: Lysholm Score and Tegner Activity Scale, functional hopping tests, isometric and isokinetic strength assessments. Results:. Both groups improved significantly (p=0.01–0.04) following 12 months after surgery. The median Lysholm score increased from 57 (34–90) to 94 (90–100) in the supervised group and 60 (41–87) to 97 (95–100) in the unsupervised group. The median Tegner Activity Scale increased from 3 (2–8) to 6 (3–8) in the supervised group and 4 (2–8) to 5 (3–10) in the unsupervised group. The combined mean symmetry indices for the hopping tests improved from 77.3+ 18.7 to 86.8+11.1 (supervised) and from 78.1+30.5 to 88.3+10.9 (unsupervised). Isometric and isokinetic strength symmetry indices for knee extension improved from 68.9+23.5 to 82.8+11.9 resp. 63.7+22.8 to 82.7+15.1 in the supervised group and from 73.6+20.5 to 76.5+17.9 resp. 69.5+24.3 to 76.9+16.9 in the unsupervised group. Eccentric strength symmetry indices for knee extension improved from 67.9+27.7 to 87.8+6.8 in the supervised group and from 71.3+17.8 to 82.6+15.6 in the unsupervised group. Conclusion:. This study could not demonstrate a benefit in a rehabilitation program supervised by a physiotherapist in our population compared to an unsupervised cohort

Abstract. Objectives. This study aims to evaluate the functional outcomes of early weight-bearing in a functional orthosis for conservatively managed, complete AT ruptures. Also we tried to evaluate the patient reported outcome with this form of treatment. Design. In this prospective study, we have analysed data from 41 patients with ultrasound diagnosed compete AT ruptures, with a gap of less than 5 cm. Every patient was treated in a functional weight-bearing orthosis (VACOped®) for 8 weeks with early weight-bearing following a specific treatment protocol, followed by rehabilitation with a trained physiotherapist. Methods. Patients were followed up with foot and ankle trained physiotherapist for at least 1 year post-injury. At final follow up, the followings were measured: calf girth, single-leg heel raise height and repetitions. Furthermore, ATRS score and a patient feedback were taken on this final visit. Result. The mean ATRS score was 82.1, with a re-rupture rate of only 2% as compared to 5% in normal orthosis. The average calf bulk difference was 1.6 cm, the average heel raise height difference was 1.8cm and a heel raise repetition difference of 6. There was a statistically significant correlation between ATRS score and calf muscle girth (p=0.02). However, there was no significant correlation between ATRS and heel raise height or heel raise repetitions. Conclusion. Early weight-bearing in a functional orthosis provides excellent functional outcomes for conservatively managed, complete AT ruptures, and is associated with very low re-rupture rates. A multidisciplinary approach with a guided rehabilitation programme is essential for optimising functional outcome

There are longstanding debates regarding surgical versus conservative management of Achilles tendon ruptures, however there is limited focus on rehabilitation. A specific rehabilitation programme was initiated in 2008 to unify management and improve patient outcomes. We present the results at three and a half years. In October 2008 management was streamlined under the foot and ankle surgeons and a dedicated physiotherapy service. Operative management used mainly the Achillon device (Integra) and VACOped boot with a specific rehabilitation protocol. We prospectively collected data on all patients with Achilles tendon ruptures from October 2008 to March 2012. There were 246 patients in total with four lost to follow up. 80 were treated with the Achillon system, 18 had an open repair and 144 were treated conservatively (of which 56 were partial or musculocutaneous junction tears). Three patients sustained re-rupture (1.2%), all initially treated conservatively. There were two operative complications (2%), both wound breakdowns. Two patients suffered PE's (0.8%), confirmed on VQ scan or CTPA (one operative, one conservative). One non-compliant patient healed functionally long and required a shortening procedure. The authors experience has been that using the VACOped boot with our custom rehabilitation programme in dedicated physiotherapy clinics has produced excellent results

The management of acute tendo-Achilles (TA) rupture still divides orthopaedic opinion. The advent of minimally invasive endoscopic or percutaneous techniques is thought to allow faster rehabilitation. We report the outcome of 30 patients with acute TA ruptures that have undergone percutaneous repair followed by an accelerated rehabilitation programme with early weight-bearing. A single centre, prospective cohort study was undertaken. 30 patients (21 men, 9 women; mean age: (40±9 years) with an acute TA rupture were enrolled and followed-up for an average of 12.5±2.9 months. All operations were performed under local anaesthesia, using a modified percutaneous technique, within 2 weeks of injury. Following surgery, patients were immobilised in an equinus cast for only 2 weeks then allowed to weight bear through a walker boot with 3 heel wedges, which were removed sequentially over a 6-week period. A standardised physiotherapy programme was started 2 weeks post-operatively and continued until 4 months. The primary outcome measure was the TA re-rupture rate and the Achilles tendon Total Rupture Score (ATRS) at 3 and 6 months. There were no re-ruptures in the study group. The mean 3- and 6-month ATRS was 57.75 and 86.95 respectively. This improvement was statistically significant (p<0.001). All patients were able to fully weight bear on the operated leg by the eighth week, without the walker boot. At the 6-month follow-up, the average satisfaction rate was 87±7.5%. Patients returned to their pre-rupture sports at an average of 10.4±3 months. The results of this study demonstrate that minimally invasive repair of acute TA ruptures, combined with an accelerated rehabilitation programme provides a safe and reproducible treatment option

There are a few papers in the literature to indicate the likely functional outcome of conservatively managed sportsmen in whom primary outcome cruciate ligament [ACL] healing occurs. We reviewed 298 sportsmen presenting with isolated ACL rupture that were conservatively managed with a rehabilitation programme, based on regaining proprioceptive and hamstring control, and aimed at achieving primary ACL healing. All were protected in a hinged brace. In 50 patients, the ACL was determined as having healed clinically; these patients underwent instrumented laximetry testing with KT 1000 arthrometry and were determined: IKDC A [Normal] or IKDC B [nearly normal]. An MRI was also performed which confirmed healing in 39 patients with ACL fibres parallel to Blumenstat's line. In 11 patients the ACL stump had healed to the PCL. The 50 patients were followed up for an average 16 months [range, 14 to 17 months]. 56% of patients suffered recurrent instability when they returned to their preinjury level of contact or pivoting sport. For competitive athletes, 76.5% suffered further instability on return to sport despite the four-month rehabilitation and independent arthrometry score or MRI findings. However, for occasional, recreational athletes only 7% suffered recurrent instability. This study suggests that a rehabilitation programme aimed at primary ACL healing affords satisfactory results for the occasional, recreational athlete but does not achieve the quality of restraint sufficient for contact or pivoting sports in competitive athletes. These patients suffer high levels of recurrent instability and are exposed to the risk of secondary chondral and meniscal injury

It is unclear why ACL rupture increases osteoarthritis risk, regardless of ACL reconstruction. Our aims were: 1) to establish the reliability and accuracy of a direct method of determining tibiofemoral contact in vivo with UO-MRI, 2) to assess differences in knees with ACL rupture treated nonoperatively versus operatively, and 3) to assess differences in knees with ACL rupture versus healthy knees. We recruited a convenience sample of patients with prior ACL rupture. Inclusion criteria were: 1) adult participants between 18–50 years old; 2) unilateral, isolated ACL rupture within the last five years; 3) if reconstructed, done within one year from injury; 4) intact cartilage; and 5) completed a graduated rehabilitation program culminating in return to sport or recreational activities. Participants were excluded if they had other ligament ruptures, osteoarthritis, an incompletely rehabilitated injury, were prohibited from undergoing MRI, or had a history of ACL re-rupture. Using the UO-MRI, we investigated tibiofemoral contact area, centroid location, and six degrees of freedom alignment under standing, weightbearing conditions with knees extended. We compared patients with ACL rupture treated nonoperatively versus operatively, and ACL ruptured knees versus healthy control knees. We assessed reliability using the intra-class correlation coefficient, and accuracy by comparing UO-MRI contact area with a 7Tesla MRI reference standard. We used linear mixed-effects models to test the effects of ACL rupture and ACL reconstruction on contact area. We used a paired t test for centroid location and alignment differences in ACL ruptured knees versus control knees, and the independent t test for differences between ACL reconstruction and no reconstruction. Analyses were performed using R version 3.5.1. We calculated sample size based on a previous study that showed a contact area standard deviation of 13.6mm2, therefore we needed eight or more knees per group to detect a minimum contact area change of 20mm2with 80% power and an α of 0.05. We recruited 18 participants with ACL rupture: eight treated conservatively and 10 treated with ACL reconstruction. There were no significant differences between the operative and nonoperative ACL groups in terms of age, gender, BMI, time since injury, or functional knee scores (IKDC and KOOS). The UO-MRI demonstrated excellent inter-rater, test-retest, and intra-rater reliability with ICCs for contact area and centroid location ranging from 0.83–1.00. Contact area measurement was accurate to within 5% measurement error. At a mean 2.7 years after injury, we found that ACL rupture was associated with a 10.4% larger medial and lateral compartment contact areas (P=0.001), with the medial centroid located 5.2% more posterior (P=0.001). The tibiae of ACL ruptured knees were 2.3mm more anterior (P=0.003), and 2.6° less externally rotated (P=0.010) relative to the femur, than contralateral control knees. We found no differences between ACL reconstructed and nonreconstructed knees. ACL rupture was associated with significant mechanical changes 2.7 years out from injury, which ACL reconstruction did not restore. These findings may partially explain the equivalent risk of post-traumatic osteoarthritis in patients treated operatively and nonoperatively after ACL rupture

Hinged elbow orthoses (HEO) are often used to allow protected motion of the unstable elbow. However, biomechanical studies have not shown HEO to improve the stability of a lateral collateral ligament (LCL) deficient elbow. This lack of effectiveness may be due to the straight hinge of current HEO designs which do not account for the native carrying angle of the elbow. The aim of this study was to determine the effectiveness of a custom-designed HEO with adjustable valgus angulation on stabilizing the LCL deficient elbow. Eight cadaveric upper extremities were mounted in an elbow motion simulator in the varus position. An LCL injured (LCLI) model was created by sectioning of the common extensor origin, and the LCL. The adjustable HEO was secured to the arm and its effect with 0°, 10°, and 20° (BR00, BR10, BR20) of valgus angulation was investigated. Varus-valgus angles and ulnohumeral rotations were recorded using an electromagnetic tracking system during simulated active elbow flexion with the forearm pronated and supinated. We examined 5 elbow states, intact, LCLI, BR00, BR10, BR20. There were significant differences in varus and ER angulation between different elbow states with the forearm both pronated and supinated (P=0 for all). The LCLI state with or without the brace resulted in significant increases in varus angulation and ER of the ulnohumeral articulation compared to the intact state (P 0.05). The difference between each of the brace angles and the LCLI state ranged from 1.1° to 2.4° for varus angulation and 0.5° to 1.6° for ER. Although there was a trend toward decreasing varus and external rotation angulation of the ulnohumeral articulation with the application of this adjustable HEO, none of the brace angles examined in this biomechanical investigation was able to fully restore the stability of the LCL deficient elbow. This lack of stabilizing effect may be due to the weight of the brace exerting unintentional varus and torsional forces on the unstable elbow. Previous investigations have shown that the varus arm position is highly unstable in the LCL deficient elbow. Our results demonstrate that application of an HEO with an adjustable carrying angle does not sufficiently stabilize the LCL deficient elbow in this highly unstable position and varus arm position should continue to be avoided in the rehabilitation programs of an LCL deficient elbow

Surgeries for reverse total shoulder arthroplasty (RTSA) significantly increased in the last ten years. Initially developed to treat patients with cuff tear arthropathy (CTA) and pseudoparalysis, wider indications for RTSA were described, especially complex proximal humerus fractures. We previously demonstrated in patients with CTA a different sequence of muscular activation than in normal shoulder, with a decrease in deltoid activation, a significant increase of upper trapezius activation and slight utility of the latissimus dorsi. There is no biomechanical study describing the muscular activity in patients with RTSA for fractures. The aim of this work is to describe the in vivo action of RTSA in patients with complex fractures of the proximal humerus. We conducted an observational prospective cohort study comparing 9 patients with RTSA for complex humerus fracture (surgery more than 6 months, healed tuberosities and rehabilitation process achieved) and 10 controls with normal shoulder function. Assessment consisted in a synchronized analysis of range of motion (ROM) and muscular activity on electromyography (EMG) with the use of 7 bipolar cutaneous electrodes, 38 reflective markers and 8 motion-recording cameras. Electromyographic results were standardized and presented in muscular activity (RMS) adjusted with maximal isometric contractions according to the direction tested. Five basic movements were evaluated (flexion, abduction, neutral external rotation, external rotation in 90° of abduction and internal rotation in 90° of abduction). Student t-test were used for comparative descriptive analysis (p < 0,05). The overall range of motion with RTSA is very good, but lower than the control group: flexion 155.6 ± 10 vs 172.2 ± 13.9, p<0.05, external rotation at 90° 55.6 ± 25 vs 85.6 ± 8.8, p<0,05, internal rotation at 90° 37.8 ± 15.6 vs 52.2 ± 12, p<0,05. The three heads of the deltoid are more stressed during flexion and abduction in the RTSA group (p. The increased use of the 3 deltoid chiefs does not support the hypothesis proposed by Grammont when the RTSA is performed for a complex proximal humerus fracture. This can be explained by the reduced dispalcement of the rotation center of the shoulder in these patients compared to those with CTA. These patients also didn't present shoulder stiffness before the fracture. The maximal muscle activity of the trapezius in flexion and of the latissimus dorsi in flexion and abduction had not been described to date. These new findings will help develop better targeted rehabilitation programs. In addition, the significant role of the latissimus dorsi must question the risks of its transfer (L'Episcopo procedure) to compensate for external rotation deficits

There has been growing interest in the literature regarding evaluation of functional outcomes in patients undergoing total knee arthroplasty (TKA) and total hip arthroplasty (THA) while suffering from depression and using selective serotonin reuptake inhibitors (SSRI). Previous literature has shown that these patients have lower post-operative functional scores compared to those without SSRI use and with multiple musculoskeletal co-morbidities. This might be the result of potentially suboptimal motivation and participation in the post-operative rehabilitation programs. One recent study from a single center has suggested a reduction in adverse events in patients undergoing arthroplasty while on SSRI. The purpose of this study is to evaluate the post operative functional scores of patients on SSRI and compare them with the patients not prescribed SSRIs. A retrospective data analysis was performed on patients who had primary TKA and primary THA between 1st June 2014 and 31st May 2017. The patients into two groups. In the first, patients received SSRI for at least one year before the surgery while in group two, patients did not receive SSRI. Outcome measures included Western Ontario and McMaster university osteoarthritis index (WOMAC) and EQ5D5L scores at pre surgery, three months and 12 months post surgery. Chi-square and t test was used to compare categorical variables and continuous variables respectively. Multivariate linear regression was conducted to compare the change of scores between the two groups and was adjusted for age, gender, and comorbidities. These outcome scores were analyzed separately for TKA and THA. In the TKA group, there were 1,452 patients using SSRI and 15,981 not using SSR. In the THA group there were 851 patients using SSRIs and 10,102 patients without SSRIs. The baseline WOMAC for TKA patients was 45.6 for the controls and 41.8 for those patients on SSRIs (p < 0 .001). The baseline EQ5DL was 0.53 and 0.46 in the same groups (p < 0 .001). The baseline WOMAC for THA patients was 39.1 for the controls and 36.2 for patients using SSRIs (p < 0 .001). The baseline EQ5DL scores were 0.43 and 0.37respectively, again indicating patients on SSRI therapy had lower baseline scores (p < 0 .001). There was improvement in WOMAC and EQ5DL scores in all patient groups at 3 months and 12 months. After adjusting for gender, age, comorbidities and baseline score, THA patients not using SSRI showed a greater improvement in their WOMAC and EQ5DL scores than those prescribed SSRIs, WOMAC (p=0.008), EQ5DL (p=0.001). TKA patients showed a similar outcome but only the EQ5DL was statistically significant, WOMAC (p=0.12), EQ5DL (p=0.036). Our results show that patients on SSRI have lower preoperative WOMAC and EQ5DL scores at baseline when compared to patients not undergoing treatment for depression or anxiety with SSRIs. After arthroplasty, patients using SSRIs show significant improvement at 12 months but the improvement is smaller than the group not using SSRIs

Acute metatarsal fractures are a common extremity injury. While surgery may be recommended to reduce the risk of nonunion or symptomatic malunion, most fractures are treated with nonoperative management. However, there is significant variability between practitioners with no consensus among clinicians on the most effective nonoperative protocol, despite how common the form of treatment. This systematic review identified published conservative treatment modalities for acute metatarsal fractures and compares their non-union rate, chronic pain, and length of recovery, with the objective of identifying a best-practices algorithm. Searches of CINAHL, EMBASE, MEDLINE, and CENTRAL identified clinical studies, level IV or greater in LOE, addressing non-operative management strategies for metatarsal fractures. Two reviewers independently screened the titles, abstracts, and full texts, extracting data from eligible studies. Reported outcome measures and complications were descriptively analyzed. Studies were excluded if a rehabilitation program outlining length of immobilization, weight-bearing and/or strengthening approaches was not reported. A total of 12 studies (8 RCTs and 4 PCs), from the 2411 studies that were eligible for title screening, satisfied inclusion criteria. They comprised a total of 610 patients with acute metatarsal fractures, with a mean age of 40.2 years (range, 15 – 82). There were 6 studies that investigated avulsion fractures, 2 studies on true Jones fractures, and 4 studies with mixed fracture types. Studies assessed a variety of treatment modalities including: WB and NWB casts, elasticated support bandages, hard-sole shoes, plaster slippers, metatarsal shoe casts, and air cast boots. Most studies investigated the outcomes of NWB casts and elasticated support bandages. The NWB short leg cast had no reported non-unions, delayed-unions, or refractures for avulsion fractures. In true Jones fractures, there was an average non-union rate of 23.6% (range, 5.6 – 27.8%), delayed-union rate of 11.8% (range, 5.6 – 18.8%), and refracture rate of 3% (range, 0 – 5.6%). Overall, the average AOFAS score was 87.2 (range, 84 – 91.7) and the average VAS score was 83.7 (range, 75 – 93). The elasticated support bandage had an average non-union rate of 3.4% (range, 0 – 12%), and delayed-union rate of 3.8% for acute avulsion fractures, with no reported refractures. No included study arm investigated outcomes of elasticated support bandages for the true Jones fracture. The average AOFAS score for elasticated support bandages was 93.5 (range, 90 – 100). The average VAS score was 88.9 (range, 90 – 100). Most acute metatarsal fractures heal well, with good-to-excellent functional outcomes and moderate-to-high patient satisfaction. Conservative strategies for avulsion fractures are highly successful and based on this data the authors recommend patients undergo a schedule that involves 3 – 4 weeks in an elasticated support bandage, short leg cast, or equivalent, and WB thereafter as tolerated, with return-to-activity after clinical union. Despite poorer conservative outcomes for true Jones fractures, patients should undergo 8 weeks in a NWB short leg cast, followed by a walking cast or hard-sole shoe for an additional 4 – 6 weeks, or until clinical union. However, surgical consultation is recommended

Introduction. Gait laboratory measurement of whole-body kinematics and ground reaction forces during a wide range of activities is frequently performed in joint replacement patient diagnosis, monitoring, and rehabilitation programs. These data are commonly processed in musculoskeletal modeling platforms such as OpenSim and Anybody to estimate muscle and joint reaction forces during activity. However, the processing required to obtain musculoskeletal estimates can be time consuming, requires significant expertise, and thus seriously limits the patient populations studied. Accordingly, the purpose of this study was to evaluate the potential of deep learning methods for estimating muscle and joint reaction forces over time given kinematic data, height, weight, and ground reaction forces for total knee replacement (TKR) patients performing activities of daily living (ADLs). Methods. 70 TKR patients were fitted with 32 reflective markers used to define anatomical landmarks for 3D motion capture. Patients were instructed to perform a range of tasks including gait, step-down and sit-to-stand. Gait was performed at a self-selected pace, step down from an 8” step height, and sit-to-stand using a chair height of 17”. Tasks were performed over a force platform while force data was collected at 2000 Hz and a 14 camera motion capture system collected at 100 Hz. The resulting data was processed in OpenSim to estimate joint reaction and muscle forces in the hip and knee using static optimization. The full set of data consisted of 135 instances from 70 patients with 63 sit-to-stands, 15 right-sided step downs, 14 left-sided step downs, and 43 gait sequences. Two classes of neural networks (NNs), a recurrent neural network (RNN) and temporal convolutional neural network (TCN), were trained to predict activity classification from joint angle, ground reaction force, and anthropometrics. The NNs were trained to predict muscle and joint reaction forces over time from the same input metrics. The 135 instances were split into 100 instances for training, 15 for validation, and 20 for testing. Results. The RNN and TCN yielded classification accuracies of 90% and 100% on the test set. Correlation coefficients between ground truth and predictions from the test set ranged from 0.81–0.95 for the RNN, depending on the activity. Predictions from both NNs were qualitatively assessed. Both NNs were able to effectively learn relationships between the input and output variables. Discussion. The objective of the study was to develop and evaluate deep learning methods for predicting patient mechanics from standard gait lab data. The resulting models classified activities with excellent performance, and showed promise for predicting exact values for loading metrics for a range of different activities. These results indicate potential for real-time prediction of musculoskeletal metrics with application in patient diagnostics and rehabilitation.

Background. Total knee arthroplasty (TKA) is offered to patients who have end-stage knee osteoarthritis to reduce pain and improve functional performance. Knee edema and pain deteriorate the patients' outcomes after TKA at early period. By quantifying the patients' early outcome deficits and their potential relationships to edema and pain may assist in the design of in-patient rehabilitation programs. Objectives. The aim of this study was to investigate of the effect of knee swelling on early patients' outcomes after primary TKA. Design and Methods. The study group consisted of 61 patients (10 males, 51 females), who underwent primary TKR because of knee arthrosis were included in the study with mean age 65.2±9 years. Patients were evaluated regarding knee circumference (10 cm superior of midpoint of patella, midpoint of patella, 10 cm distal of midpoint of patella), pain (Numeric Pain Rating Scale (NPRS)), knee range of motion (ROM), the day of active straight leg raise, knee function score (Hospital for Special Surgery (HSS)), Functional activities were evaluated using the Iowa Level of Assistance Scale (ILAS) and walking speed was evaluated using the Iowa Ambulation Velocity Scale (IAVS). Results. There were moderate significant correlation between knee circumference (10 cm superior of midpoint of patella; r=0.328, p=0.001, midpoint of patella; r=0.310, p=0.002, 10 cm distal of midpoint of patella; r=0.300, p=0.003) and IAVS. While, significant low correlation was found between pain level and knee ROM (r=−0.272, p=0.008), there was strong significant correlation between pain level and HSS (r=0.866, p<0.001). There was not significant correlation between knee swelling and all the other measurement, and also between pain and all the other measurement (p>0.05). Conclusion. The moderate correlation between knee swelling and IVAS, low correlation between pain and knee ROM, and also strong correlation between pain and HSS suggests that improved postoperative knee swelling and pain could be important to enhance the potential benefits of TKA in early stage. With improvement in knee swelling and pain the patient may obtain good functional outcomes and knee score

The goals of any rehabilitation protocol should be to control pain, improve ambulation, maximise range of motion, develop muscle strength, and provide emotional support. Over 85% of TKA patients will recover knee function regardless of which rehabilitation protocol is adopted but the process can be facilitated by proper pain control, physical therapy, and emotional support. The remaining 15% of patients will have difficulty obtaining proper knee function secondary to significant pain, limited preoperative motion, and/or the development of arthrofibrosis. This subset will require a special, individualised rehabilitation program, which may involve prolonged oral analgesia, continued physical therapy, more diagnostic studies and occasionally manipulation. Controlling pain is the mainstay of any treatment plan. The program described herein has been used at Ranawat Orthopaedics over the last 10 years in more than 2000 TKAs

The etiology of the flexion contracture is related to recurrent effusions present in a knee with end-stage degenerative joint disease secondary to the associated inflammatory process. These recurrent effusions cause increased pressure in the knee causing pain and discomfort. Patients will always seek a position of comfort, which is slight flexion. Flexion decreases the painful stimulus by reducing pressure in the knee and relaxing the posterior capsule. Unfortunately, this self-perpetuating process leads to a greater degree of contracture as the disease progresses. Furthermore, patients rarely maintain the knee in full extension. Even during the gait cycle the knee is slightly flexed. As their disease progresses, patients limit their ambulation and are more frequently in a seated position. Patients often report sleeping with a pillow under their knee or in the fetal position. All of these activities increase flexion contracture deformity. Patients with excessive deformity >40 degrees should be counseled regarding procedural complexity and that increasing constraint may be required. Patients are seen preoperatively by a physical therapist and given a pre-arthroplasty conditioning program. Patients with excessive flexion contracture are specifically instructed on stretching techniques, as well as quadriceps rehabilitation exercises. The focus in the postoperative physiotherapy rehabilitation program continues toward the goal of full extension. Patients are instructed in appropriate stretching regimes. Patients are immobilised for the first 24 hours in full extension with plaster splints, such as with a modified Robert Jones dressing. This dressing is removed on postoperative day one. The patient is then placed in a knee immobiliser and instructed to wear it at bed rest, during ambulation and in the evening, only removing for ROM exercises. In cases of severe flexion deformity >30 degrees, patients are maintained in full extension for 3–4 weeks until ROM is begun. Patients are encouraged to use a knee immobiliser for at least the first 6 weeks postoperatively. Treating patients with flexion contracture involves a combination of bone resection and soft tissue balance. One must make every effort to preserve both the femoral and tibial joint line. In flexion contracture the common error is to begin by resecting additional distal femur, which may result in joint line elevation and mid-flexion instability. The distal femoral resection should remove that amount of bone being replaced with metal. Attention should be directed at careful and meticulous balance of the soft tissues and release of the contracted posterior capsule with re-establishment of the posterior recess, which will correct the majority of flexion contractures. Inability to achieve ROM after TKA represents a frustrating complication for both patient and surgeon. Non-operative treatments for the stiff TKA include shoe lift in contralateral limb, stationery bicycle with elevated seat position, extension bracing, topical application of hand-held instruments to areas of soft tissue-dysfunction by a trained physical therapist over several outpatient sessions, and use of a low load stretch device. Manipulation under anesthesia is indicated in patients after TKA having less than 90 degrees ROM after 6 weeks, with no progression or regression in ROM. Other operative treatments range from a downsizing exchange of the polyethylene bearing to revision with a constrained device and low-dose irradiation in cases of severe arthrofibrosis

The goals of any rehabilitation protocol should be to control pain, improve ambulation, maximise range of motion, develop muscle strength, and provide emotional support. Over 85% of TKA patients will recover knee function regardless of which rehabilitation protocol is adopted but the process can be facilitated by proper pain control, physical therapy, and emotional support. The remaining 15% of patients will have difficulty obtaining proper knee function secondary to significant pain, limited preoperative motion, and/or the development of arthrofibrosis. This subset will require a special, individualised rehabilitation program, which may involve prolonged oral analgesia, continued physical therapy, more diagnostic studies and occasionally manipulation. Controlling pain is the mainstay of any treatment plan. The program described herein has been used at Ranawat Orthopaedics over the last 10 years in more than 2000 TKAs

Bowel management following joint replacement is often neglected leading lot of patient distress, with the advent of the enhanced orthopedic rehabilitation program, there is a need of a guideline to ensure prompt and quick recovery of bowel habits before discharge. Our aim was to identify the incidence of constipation in joint replacement patients, to evaluate the current practice of bowel management and formulate a protocol for management of constipation to improve the practice. We conducted a prospective study of 50 patients who underwent joint replacement procedures at our institute between September and October 2015. Following initial audit, we formulated a protocol for bowel management, and performed a re-audit by collecting a prospective data of 50 patients. The statistical analysis was done and calculating the mean and standard deviation for continuous variable and Fischer's exact test was used and significance level was set at 0.05. Incidence of constipation was 88% and laxatives were prescribed in 42%. More importantly, there was no correlation between constipation and pre operative fasting (p Value 0.33), post operative fasting (p Value 0.1822), type of surgery (p value 1.00) and type of anaesthesia (p Value 0.27). Following introduction of bowel protocol the laxative prescription increased to 98% (Prophylactic in 81%), consequently the incidence of constipation reduced to 18%. Implementing bowel protocol significantly will improve the patient care and reduce the rate of complications

The goals of any rehabilitation protocol should be to control pain, improve ambulation, maximise range-of-motion, develop muscle strength and provide emotional support. Over 85% of TKR patients will recover knee function regardless of which rehabilitation protocol is adopted but the process can be facilitated by proper pain control, physical therapy and emotional support. The remaining 15% of patients will have difficulty obtaining proper knee function secondary to significant pain, limited pre-operative motion and/or the development of arthrofibrosis.
