Cause Of Residual Pain Research Articles

Влияние баланса разгибательно-сгибательного промежутка при первичном тотальном эндопротезировании колена на функцию сустава

Introduction A poorly balanced, unstable, or stiff joint is a major cause of residual pain, dissatisfaction, and revision after total knee replacement (TKA), but the definition of a well-balanced joint remains debatable. The aim of the study was to explore the influence of the knee space and the extensionflexion gap being accurately restored in primary TKA on the knee function and the quality of life of the patient. Material and methods A prospective, single-center, randomized, controlled study was performed for 41 patients with grade 3-4 knee osteoarthritis. (K-L): the first group (n = 21) underwent primary TKA with the method proposed for precise realignment of the extension-flexion gap, the second group (n = 20) underwent standard arthroplasty. The patients had CT scans of the knee performed preoperatively and postoperatively, and VAS scale pain, knee joint scales: OKS, FJS‑12, KSS (pain and function), SF-36 (parameters: PF, RP, BP, GH, VI, SF, RE, MH) were used at 3, 6 and 12 months. Results Comparison of the standing height of the joint space preoperatively and postoperatively showed a high statistical significance measuring about 20.7 % in frontal plane (group 1: 2.06 ± 2.368, group 2: 2.629 ± 2.455, р < 0.001), 28.2 % in the sagittal projection (group 1: 2.657 ± 2.143, group 2: 3.7 ± 1.717, р < 0.001), i.e., the method proposed allowed for more accurate positioning of the extension gap by 20.7 %, the flexion gap by 28.2 % and more accurate positioning of the knee space level. Preoperative and postoperative VAS, OKS, FJS-12 and SF-36 scores showed significant positive dynamics in both groups with no statistically significant difference between the groups. A statistically significant difference was seen in the functional KSS score in the groups measuring 90.6 ± 3.5 in group 1 - 12 months after surgery - and 85.6 ± 4.2 (p < 0.001) in group 2 - 12 months after surgery. Conclusion The study demonstrated the simple and effective technique proposed for positioning the flexion and extension gap of the knee joint in primary TKA and facilitated more accurate positioning of the implant and improved knee function at standard testing 12 months after surgery.

THE ROLE OF DISCOGENOUS RADICULOPATHIES AND SPONDYLOLYSTHESIS IN THE STRUCTURE OF PAIN SYNDROME AFTER TOTAL HIP ARTHROPLASTY

Resume. In the structure of complications, pain syndrome, which is not associated with instability of the components of the endoprosthesis or infection, remains a serious problem due to difficulties in diagnosis and treatment. The cause of residual pain may be the presence in the patient of discogenic radiculopathy or spon-dylolisthesis of the lumbar spine. The aim of the study. To determine the role of discogenic radiculopathies and spondylolisthesis of the lumbar spine in the structure of pain after hip arthroplasty. Materials and methods. A sample and retrospective analysis of case histories of 138 patients with hip and lumbar syndrome, who under-went hip arthroplasty in the clinic of orthopedics and traumatology of adults SI "ITO NAMS of Ukraine". All patients were examined clinically and radiologically. Additionally, all patients were examined by a neurolo-gist to determine the neurological status of patients, diagnosis. Evaluation of the effectiveness of treatment of patients with residual effects of discogenic radiculopathy and spondylolisthesis after hip arthroplasty was performed on the functional scale of Oswestry. Results. The analysis of the patient database revealed a statisti-cally significant (p≤0.05) predominance of patients with the presence of disc herniation at the level of L3-L4 and hypolordosis. The survey revealed 9 cases of discogenic radiculopathy and 6 cases of spondylolisthesis in patients with PD, which amounted to 6.5% and 4.5% of the total number of examined patients. The high effi-ciency of the developed treatment-and-prophylactic measures in patients with discogenic radiculopathy or spondylolisthesis and lumbar-lumbar syndrome has been determined. Timely appointment of complex conserva-tive and operative methods allowed to achieve satisfactory results in 100% of cases. Conclusions. Studies to determine the role of discogenic radiculopathy and spondylolisthesis of the lumbar spine in the structure of pain after hip arthroplasty will contribute to the further development of clinical, diagnostic and treatment algorithms for patients with hip and lumbar syndrome.

FEATURES OF FORMATION OF CONTRACTURES OF A HIP JOINT AT PATIENTS WITH A HIP-LUMBAR SYNDROME

Resume. With significant destructive changes in the hip joints, endoprosthesis is the main method of surgical treatment of coxarthrosis. However, according to the Swedish and Canadian registries, 17-20% of patients have pain after arthroplasty. The cause of residual pain may be a concomitant lesion of the spine, and the study of issues related to the clinical features of the hip-lumbar syndrome are relevant from a scientific and practical point of view. The purpose of the study: to analyze the clinical and radiological picture of patients with coxarthrosis with concomitant pathology of the spine, to investigate the dependence of the severity of flexion contracture of the hip, variable parameters (pelvic angle RT and lumbar lordosis GLL) from constant angle and angle; to study the features of the clinical course of hip-lumbar syndrome. Materials and methods. An analysis of the results of examination of 150 patients with stage III-IV idiopathic coxarthrosis who under-went hip arthroplasty in the clinic of orthopedics and traumatology of adults of the State Institution "ITO NAMS of Ukraine" was performed. Hip pain and functional impairment were assessed according Harris and Womac scales also before hip arthroplasty and 3 months after surgery. Results. Analysis of the obtained data shows that with an increase in the angle of inclination of the pelvis and flexion contracture, the values of the parameters of the angle of pelvic deviation increase, which causes a statistically significant increase in the angle of lumbar lordosis. The correlation coefficients between the parameters PI-PT and PI-GLL were 0.65±0.15 and 0.74±0.11, respectively. Conclusions. Pain in patients with small contracture of the hip joint is associated with neuro-dystrophic syndrome in osteochondrosis of the lumbar spine, in patients with larger contracture - with spondyloarthritis. In the vertical position of the sacrum - GLL - the smallest, least pro-nounced and flexion contracture of the hip joint. On the contrary, in the horizontal position of the sacrum in patients with hyperlordosis and significant, more than 10 ° contracture in the hip joints.

Complex Regional Pain Syndrome Following Total Knee Arthroplasty.

Complex regional pain syndrome (CRPS) is an uncommon cause of residual pain after total knee arthroplasty (TKA). The presentation is variable, and there is no gold standard diagnostic test. Diagnosis is more difficult after TKA because some classic signs of CRPS may be unreliable and imaging may be difficult to interpret. Early intervention is the most important factor in predicting improvement, necessitating high suspicion in patients with exaggerated pain and stiffness after excluding more common causes. This article reviews the literature regarding CRPS following TKA, explains the diagnosis, and discusses treatment. [Orthopedics. 2020;43(6):e486-e491.].

Management of Painful Shoulder Arthroplasty: A Narrative Review.

Despite the recent advances in surgical techniques, the percentage of painful shoulder arthroplasties is still high (more than 10%). The causes of residual pain after shoulder arthroplasty, and the resulting treatment solutions, are many and different. The most common complications of shoulder prosthesis are infections, aseptic loosening, modular components disassembling, metal hypersensitivity, and instability. There are also implant-related complications such as glenoid wear in hemiarthroplasty, rotator cuff tear in anatomical total shoulder arthroplasty, scapular notching, and acromion fracture in reverse shoulder arthroplasty. Several of these complications can be avoided with a careful selection of the implants, a proper surgical technique and a precise implant positioning. The execution of a more accurate preoperative planning and the possible use of patient-specific implants are expected to translate into better clinical results in the future. We provide the reader with recent evidence on the causes and therapeutic options of this condition.

FCR Interposition Arthroplasty for Concomitant STT and CMC Arthritis.

Arthritis of scaphotrapeziotrapezoid joint is common and can be seen in association with first carpal metacarpal (CMC) arthritis. Untreated scaphotrapeziotrapezoid arthritis may be a cause of residual pain after CMC arthroplasty. There are various treatment options described in the literature ranging from arthrodesis, resection arthroplasty, interpositional arthroplasty, and implant arthroplasty. We describe a novel technique of flexor carpi radialis (FCR) tendon interposition to tackle this condition. Our common treatment for CMC arthritis is trapezium resection with ligament reconstruction and tendon interposition with half of the FCR. With this procedure, through the same exposure, the proximal part of the trapezoid is resected. An anchor is placed into the trapezoid and the sutures are passed through a remnant of the FCR. Thus the FCR is pulled in between the scaphoid and the trapezoid and secured in place. We performed this procedure in 13 hands with average follow-up of 36 months. All patients were satisfied with the procedure and were pain free at their last follow-up. The advantage of this procedure is the use of the FCR, which is already available in the field and requires very little additional procedure.

Diagnostic Algorithm for Residual Pain After Total Knee Arthroplasty.

Although total knee arthroplasty is a successful and cost-effective procedure, patient dissatisfaction remains as high as 50%. Postoperative residual knee pain after total knee arthroplasty, with or without crepitation, is a major factor that contributes to patient dissatisfaction. The most common location for residual pain after total knee arthroplasty is anteriorly. Because residual pain has been associated with an un-resurfaced patella, this review includes only registry data and total knee arthroplasty with patella replacement. Some suggest that the pathogenesis of residual knee pain may be related to mechanical stimuli that activate free nerve endings around the patellofemoral joint. Various etiologies have been implicated in residual pain, including (1) low-grade infection, (2) midflexion instability, and (3) component malalignment with patellar maltracking. Less common causes include (4) crepitation and patellar clunk syndrome; (5) patellofemoral symptoms, including overstuffing and avascular necrosis of the patella; (6) early aseptic loosening; (7) hypersensitivity to metal or cement; (8) complex regional pain syndrome; and (9) pseudoaneurysm. Because all of these conditions can lead to residual pain, identifying the etiology can be a difficult diagnostic challenge. Often, patients with persistent pain and normal findings on radiographs and laboratory workup may benefit from a diagnostic injection or further imaging. However, up to 10% to 15% of patients with residual pain may have unexplained pain. This literature review summarizes the findings on the causes of residual pain and presents a diagnostic algorithm to facilitate an accurate diagnosis for residual pain after total knee arthroplasty.

Improved Visualization of the 70° Arthroscope in the Treatment of Talar Osteochondral Defects

Osteochondral defects (OCDs) of the talus are a common cause of residual pain after ankle injuries. When conservative treatment fails, arthroscopic debridement combined with drilling/microfracturing of the lesion (bone marrow stimulation [BMS] procedures) has been shown to provide good to excellent outcomes. Not uncommonly, talar OCDs involve the borders of the talar dome. These uncontained lesions are sometimes difficult to visualize with the 30° arthroscope, with potential negative effect on the clinical outcome of an arthroscopic BMS procedure. The use of the 70° arthroscope has been described for a multitude of common knee, shoulder, elbow, and hip procedures. The purpose of this article is to show the usefulness of the 70° arthroscope in arthroscopic BMS procedures, pointing out which kinds of talar OCDs can benefit most from its use.

Anterior fibrous bundle: a cause of residual pain and restrictive plantar flexion following ankle sprain

To describe anterior fibrous bundle as an intra-articular residual disorder following ankle sprain. Between January 1998 and January 2009, we performed arthroscopy on 10 patients (7 males, 3 females; median age, 25 years; age range, 17-43 years) who had the uncommon problem of anterior ankle pain accompanied by restriction of plantar flexion following an ankle sprain. Pre-operative magnetic resonance imaging revealed osteochondral lesions (OCLs) of the talar dome in 3 patients, but no other findings that could explain restricted plantar flexion. All patients underwent arthroscopy for investigation and treatment of the cause of symptoms, and the 3 patients with OCL underwent additional arthroscopic drilling. Outcome was measured using the American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS) score, Visual Analogue Scale (VAS) for pain and active plantar flexion angle. In all patients, an anterior fibrous bundle was confirmed under arthroscopic investigation as the cause of symptoms and was resected arthroscopically. Median AOFAS and VAS scores improved significantly from 65 (range 61-82) and 70 (range 50-85) pre-operatively to 95 (range 84-100) and 4 (range 0-15) at final follow-up, respectively (p < 0.001). In addition, median active plantar flexion angle improved significantly from 40° (range 35-40) pre-operatively to 55° (range 45-55), (p < 0.01). An anterior fibrous bundle is one of the intra-articular residual disorders after ankle sprain that can cause restriction of plantar flexion.

Arthroscopic Assessment for Intra-articular Disorders in Residual Ankle Disability after Sprain

Background After ankle sprain, there can be many causes of disability, the origins of which cannot be determined using standard diagnostic tools. Hypothesis Ankle arthroscopy is a useful tool in identifying intra-articular disorders of the talocrural joint in cases of residual ankle disability after sprain. Study Design Cohort study (diagnosis); Level of evidence, 2. Methods The authors gathered the independent diagnostic results of physical examination, standard mortise and lateral radiography, stress radiography of the talocrural joint, and magnetic resonance imaging for 72 patients with residual ankle disability lasting more than 2 months after injury (mean, 7 months after injury). They performed arthroscopic procedures and compared the double-blind results. Results In all cases, the arthroscopic results matched those of other means of diagnosis. In 14 cases, the arthroscopic approach exceeded the capabilities of the other methods. Including duplications, 39 patients (54.2%) had anterior talofibular ligament injuries, 17 patients (23.6%) had distal tibiofibular ligament injuries, 29 patients (40.3%) had osteochondral lesions, 13 patients (18%) had symptomatic os subfibulare, 3 patients (4.2%) had anterior impingement exostosis, and 3 patients (4.2%) had impingement due to abnormally fibrous bands. There were only 2 cases in which the cause of symptoms could not be detected by ankle arthroscopy, compared with 16 cases in which the cause of disability could not be detected using standard methods. In 3 cases (17.6%) of distal tibiofibular ligament injuries, 8 cases (27.6%) of osteochondral lesions, and all 3 cases (100%) of impingement of an abnormal fibrous band, ankle arthroscopy was the only method capable of diagnosing the cause of residual ankle pain after a sprain. Conclusion The present results suggest that arthroscopy can be used to diagnose the cause of residual pain after an ankle sprain in most cases that are otherwise undiagnosable by clinical examination and imaging study.

Scapho-trapezoid arthritis: A cause of residual pain after arthroplasty of the trapezio-metacarpal joint

Scapho-trapezoid osteoarthritis may accompany osteoarthritis of the CM joint of the thumb. If the scapho-trapezoid joint is not excised when performing an excision of the trapezium with ligament reconstruction and interposition of the tendon of the FCR, the procedure may be unsuccessful. We describe three patients with four thumbs in which scapho-trapezoid osteoarthritis was associated with basal joint arthritis. In one patient, it was not recognized pre-operatively and persistent post-operative pain dictated further surgery. In the other patients, the scapho-trapezoid joint was excised primarily, with resolution of the pain. In the pre-operative assessment, the scapho-trapezoid joint should be carefully studied to prevent failure of the procedure.
