Effect of Selected Kinesiology Taping Applications on Reducing Pain and Accelerating Rehabilitation in Children with Osgood-Schlatter Disease

Introduction: Osgood-Schlatter disease (OSD) is a very common disease in children and youth during the adolescent period. This condition is characterised by pain and significant swelling along with deformity of the tibial tuberosity region, which often results in the disorder of correct gait and decreased level of physical activity.

Evaluation of posterior tibial slope relationship with common knee pathologies in pediatric and adolescent age groups in the Turkish population.

Anterior cruciate ligament rupture (ACLR), tibial eminence fracture (TEF), and Osgood-Schlatter disease (OSD) have been linked to a steep posterior tibial slope (PTS) in children and adolescents. This study aims to examine and compare these associations. 418 patients aged 8-18, 237 males and 181 females with knee pain between 2010 and 2019 were included and the patients belonged to the Turkish population. They consisted of ACLR (n = 47), TEF (n = 22), OSD (n = 51), and a control group (n = 298). The study and control groups were compared for PTS, sex, and age, with ACLR, TEF, OSD, retrospectively. The ACLR, OSD, and TEF groups had higher PTS values than the control group (P < 0.001). There was no significant difference in ACLR-OSD, ACLR-TEF, and OSD-TEF comparisons (P = 0.22, P = 0.99, and P = 0.99, respectively). PTS increase was linked to ACLR, TEF, and OSD in the multinomial regression analysis, (P < 0.001). Increase in PTS was associated with ACLR, TEF, and OSD for both males and females (independently of other factors; ACLR: P < 0.001, P < 0.001, OR: 1.59, OR: 2.63, TEF: P = 0.001, P < 0.001, OR: 1.98, OR: 1.44; OSD: P = 0.001, P < 0.001, OR: 1.49, OR: 1.28 for males and females respectively). ACLR, TEF, and OSD are associated with increased PTS in the pediatric and adolescent age groups, and there are differences between these pathologies in terms of the amount of PTS increase, age, and sex. Consideration of age and gender in pediatric and adolescent patients with increased PTS may be useful in predicting pathologies associated with increased PTS. Level of evidence: III retrospective comparative study.

Correlation of Tibial Tubercle Overgrowth With Increased Posterior Tibial Slope: A Novel Radiographic Assessment.

An elevated posterior tibial slope (PTS) is associated with an increased risk for anterior cruciate ligament and meniscal injury. Recent evidence suggests that the PTS is elevated in patients with Osgood-Schlatter disease. To determine whether there is an association between objective measures of anterior tibial tubercle growth and PTS. Cross-sectional study; Level of evidence, 3. A total of 100 radiographs were randomly selected from a sample of patients who had received a lateral knee radiograph that captured at least 15 cm of the tibia distal to the knee joint line at a single institution between December 2020 and March 2022. The PTS was measured, and tibial tubercle growth was quantified with 2 novel measurements. For these measurements, a line was drawn on the radiograph from the most anterosuperior point on the tibia to the point on the anterior cortex of the tibia 10 cm distal from the starting point. The tibial tubercle height (TTH) was measured as the perpendicular distance from this line to the most prominent portion of the anterior tibia. The anterior tibial tubercle angle (TTA) was measured as the angle between the endpoints of the line made previously and the most prominent portion of the tibial tubercle, with a more acute angle indicating a more prominent tibial tubercle. The relationship between TTA, TTH, and PTS was evaluated using a univariate linear regression model. The mean patient age was 33.1 ± 14.1 years. The mean TTA was 158.6°± 4.7°, the mean TTH was 8.8 ± 2.0 mm, and the mean PTS was 9.7°± 2.6°. A significant correlation was found between PTS and TTA (r = -0.46; β = -0.46; P < .001) as well as TTH (r = 0.43; β = 0.43; P < .001). Objective measures of anterior tibial tubercle overgrowth correlated with an elevated PTS. Every 2.2° of anterior TTA deviation from the mean and every 2.3 mm in TTH deviation from the mean correlated with a 1° difference in the PTS. This suggests a link between the development of the tibial tubercle and PTS, and it potentially helps to explain why the PTS is elevated in certain patients.

Relationship between coordination variability and Osgood-Schlatter disease in male junior youth soccer players -cross-sectional study using an inertial measurement unit-

BackgroundOsgood-Schlatter disease is a common overuse injury, and motor coordination is discussed as a risk factor; however, no reports have examined motor coordination in young soccer players with Osgood-Schlatter disease. This study aimed to investigate the difference in motor coordination between Osgood-Schlatter disease-affected and non-affected soccer players on a junior youth soccer team. MethodsThis cross-sectional study investigated 35 young soccer players of 12–15 years of age, who completed a self-administered questionnaire covering general information, injury history, and athletic experience. An inertial measurement unit was attached to the participant's thoracic spine, lumbar spine, pelvis, thigh, and lower leg. The sagittal plane tilt angle of each body segment during squatting was analyzed. The continuous relative phase was calculated using the sagittal plane tilt angle. The mean absolute relative phase and continuous relative phase variabilities were calculated and compared between Osgood-Schlatter disease-affected and non-affected players. FindingsThe sagittal plane tilt angle of each body segment during static standing and maximum flexion did not differ between the two groups. However, the Osgood-Schlatter disease group had significantly less continuous relative phase variability between the lumbar spine and pelvis (P < 0.01, Cohen's d = 0.91). The Osgood-Schlatter disease group had significantly fewer participants with other sports experience (P = 0.032, φ = 0.36). InterpretationDysfunctional lower trunk and hip muscles may be leading to Osgood-Schlatter disease. It is suggested that a variety of physical activities should be performed in the junior age group to allow players to acquire a variety of movement patterns.

Pilot development of diagnostic tools for lower limb apophyseal injuries in children and adolescents.

Lower limb apophyseal injuries commonly occur in children and adolescents with unknown incidence and prevalence. These conditions are considered benign, but impact children and adolescents quality of life and can lead to sport withdrawal at a crucial time. The primary aim of this research was to develop self-administered tools for two of the most common apophyseal injuries. The secondary aim was to test the sensitivity and specificity of the tools. Study 1 used a three round online Delphi panel (n = 8), with expert consensus supported by robust literature. This panel developed a self-administered screening tool for calcaneal (Sever's disease) and tibial tuberosity (Osgood-Schlatter's disease) apophysitis. Study 2 tested the sensitivity and specificity of these developed tools with parents and children (n = 63) with concurrent clinical examination by a health professional. An initial sample size for Study 2 was set at 155 children however this was impacted by COVID-19 and recruitment was halted. Both tools had excellent diagnostic accuracy with an area under the curve of 83% (95% confidence interval = 0.70 to 0.95) for the posterior heel (calcaneal apophysitis) tool and 93% (95% confidence interval = 0.80 to 1.00) for the anterior of knee (tibial tuberosity apophysitis) tool using the pilot data from the 63 children. These tools may also enhance opportunities for clinicians and health service providers with pre-clinical screening to reduce wait list time and encourage low cost, self-administered management where indicated. These findings may enable large epidemiological studies to identify populations and calculate incidence and prevalence of these conditions using self report.

Real-Time Virtual Sonography-Guided Ossicle Removal in Unresolved Osgood-Schlatter Disease

Osgood-Schlatter disease (OSD) reduces participation in sports activities for adolescents, and, in unresolved cases of the disease in which daily life or sports activity after skeletal maturity are affected, surgical intervention to remove the ossicle is performed to alleviate symptoms. We present a real-time virtual sonography (RVS)–guided ossicle removal in unresolved OSD. The knee joint angle is set at 20°, which is the same position used in magnetic resonance imaging. A 1.5-cm longitudinal skin incision is made at the medial side of the tuberosity. An ultrasound probe covered with a sterile sleeve is then placed longitudinally at the level of tuberosity. The forceps is inserted to peel the patellar tendon off the posterior side of the ossicle. Then the anterior side of the ossicle is peeled off in both the transverse and longitudinal views. When the ossicle is unstable enough, forceps are used to grasp the ossicle and carefully remove it. RVS can see magnetic resonance imaging information in the surrounding area beyond what can be detected by the ultrasound probe, and RVS enables easy determination of the anatomical position of the ossicle, and removal of the ossicle is achieved with low invasiveness.

Treatment of Osgood-Schlatter disease in an adolescent athlete with liquid platelet-rich fibrin and heat-coagulated albumin gel: a case report

Background: Knee pain is one of the most frequent musculoskeletal symptoms in young physically active males. In some cases, it is very painful, can be hard to treat, and often leads to heterotopic ossification of the patellar tendon. To the best of our knowledge, there are no reported cases of remission of ossification after clinical intervention. Case Presentation: A 13-year-old Swedish boy with a 3-year anamnesis of severe Osgood-Schlatter with significant ossification of the patellar tendon at the point of tuberositas tibiae, was treated with injections of liquid platelet-rich fibrin concentrated platelet rich fibrin and heat coagulated albumin platelet rich fibrin gel (ALB-PRF) using a horizontal centrifuge system. He recovered and presented a near complete remission of ossification of the patellar tendon 2 months after treatment and could return to sport after a 3-year break. Conclusion: This case raises the hypothesis that liquid ALB-PRF gel may be an effective intervention in the treatment of Osgood-Schlatter disease. Further research is required to test this theory.

Maturation-dependent patterns of knee injuries among symptomatic pediatric soccer players on MRI.

To systematically investigate the prevalence of knee MRI findings among symptomatic pediatric soccer players with respect to skeletal maturity and to identify predictors of surgery. This IRB-approved, HIPAA-compliant retrospective study included soccer players (< 18 years of age) who underwent MRI examinations in the past 5 years (2018-2023). Two radiologists retrospectively and independently reviewed all examinations to categorize skeletal maturity and toidentify osseous and soft tissue findings. Findings were compared between maturation groups, and logistic regression models were used to identify predictors of surgery. Ninety-seven players (45 boys, 52 girls) included 39 skeletally immature, 21 maturing, and 37 mature knees. Kappa coefficient for interobserver reliability ranged between 0.65 and 1.00. Osgood-Schlatter disease (OSD) was more common among immature than maturing and mature knees (25% vs 14% and 5%, p = 0.04); anterior cruciate ligament (ACL) injurywas more common among maturing and mature than immature knees (59% and 48%, vs 15%, p < 0.01); and meniscal tears were more commonamong mature than immature and maturing knees (medial, 41% vs 18% and 14%, p = 0.03; lateral, 43% vs 21% and 19%, p = 0.04). Players in the mature group were more likely to undergo surgery (p = 0.01). The presence of an effusion (OR = 19.5, 95% CI 2.8-240.9, p = 0.01), ACL injury (OR = 170.0, 95% CI 1.3-6996.9, p < 0.01), and lateral meniscal tears (OR = 10.8, 95% CI 1.8-106.1, p = 0.02) were independent predictors of surgery. Differential patterns of injury were found among symptomatic pediatric soccer players; the presence of an effusion, ACL injury, and lateral meniscal tears were independent predictors of surgery, likely contributing to the higher rates of surgery among skeletally mature players.

Enhanced Pain Relief and Function Improvement in Children with Osgood-Schlatter Disease: Leukocyte-Rich Platelet-Rich Plasma (LR-PRP) as a Complementary Treatment to Standard Conservative Therapy.

BACKGROUND Osgood-Schlatter disease (OSD) causes pain and loss of function of the knee in growing children. This study aimed to evaluate pain and function of the knee joint in 152 growing children with chronic OSD before and after treatment with LR-PRP when used with standard conservative treatment. MATERIAL AND METHODS Treatment efficacy was evaluated using the VAS, Tegner, Lyshom, and KOOS scales. Patient satisfaction, post-surgery athletic performance, and X-ray assessment were also used to determine the success of the procedure. RESULTS We found that 75% of the subjects were satisfied with the results of the treatment, and 72% of the subjects returned to full physical activity. The analysis showed a significant decrease in the median VAS score after treatment compared to the pre-treatment score (P<0.05), and an increase in the median scores of the Tegner, Lysholm, and KOOS scales compared to the pre-treatment score (P<0.05; P<0.05; P<0.05, respectively). The results showed that the shorter the duration of the disease, the better the treatment results were received. Return to activity and patient satisfaction were highest in the study group previously rehabilitated. CONCLUSIONS LR-PRP injection of the tibial tuberosity in patients with chronic OSD with open growth cartilage is an effective and uncomplicated method. We did not observe any adverse effects, which suggests the relatively high safety of the procedure. The use of PRP in the earlier phase of the disease and additional rehabilitation before treatment significantly increases the effectiveness of treatment.

Adult Knee Pain - The Diagnostic Dilemma

Knee pain is one of the frequent reasons adult patients seek care in primary care clinics. The cause of knee pain varies, from overuse syndrome to inflammatory diseases. The Osgood-Schlatter Disease (OSD) is one of the overuse syndromes, a condition of proximal tibial apophysitis commonly seen among physically active boys, particularly young athletes aged 10-14 years, during the highest growth spurt. The common presenting symptoms are intermittent or continuous knee pain while walking or playing the sport that involves jumping or running. This condition is self-limiting, resolves within 6-18 months after the growth plates close, and responds well with conservative treatment. However, few patients might have long term sequelae that persist into adulthood. The case report presents a case of recurring knee pain in a 35-year-old man upon his re-engagement with active sports. Clinical assessment and radiological investigation confirm his condition to be consistent with OSD. The diagnosis of OSD in this patient may be another rare case of the recurrence of the childhood condition in a skeletally mature adult.&#x0D; &#x0D; Keywords: Osgood-Schlatter Disease, adult, knee pain.

ENPP1 downregulation and FGF23 upregulation in growth-related calcification of the tibial tuberosity in rats.

During tibial tuberosity growth, superficial and deep portions can be observed; however, the deep portion is not observed after the growth period, as it develops into bone tissues. Calcification in vivo is known to be constitutively suppressed by ectonucleotide pyrophosphatase/phosphodiesterase-1 (ENPP1) but promoted by tissue-nonspecific alkaline phosphatase (TNAP). FGF23 promotes calcification of enthesis. Gene expression of FGF23 increased rapidly at 13W in this study. Therefore, the tibial tuberosity is speculated to develop via Enpp1 downregulation and Tnap upregulation; however, the understanding of these processes remains unclear. Hence, in the present study, we aimed to explore the age-related structural changes and underlying gene expression changes in the tibial tuberosity of rats. Male Wistar rats were divided into three groups (3-, 7-, and 13-week-old; eight each). The tibial tuberosity superficial and deep portions were clearly observed in 3- and 7-week-old rats, but the presence of the deep portion was not confirmed in 13-week-old rats. The extracellular matrix of hypertrophic chondrocytes was calcified. Furthermore, the Enpp1 expression was the highest in 3-week-old rats and decreased with growth. The TNAP expression did not differ significantly among the groups. The deep portion area was significantly lower in 3-week-old rats than in 7-week-old rats. Generally, the extracellular matrix of the immature chondrocytes is not calcified. Therefore, we speculated that the cartilaginous tibial tuberosity calcifies and ossifies with growth. The Enpp1 expression decreased with growth, whereas the Tnap expression remained unchanged. Thus, we surmise that the tibial tuberosity calcifies with growth and that this process involves Enpp1 downregulation and FGF23 upregulation. As Osgood-Schlatter disease is closely related to the calcification of the tibial tuberosity, these findings may help clarify the pathogenesis of this disease.

Anterior knee pain in young athletes: Osgood Schlatter or Sinding-Larsen-Johansson disease?

Osgood-Schlatter disease (OSD) and Sinding-Larsen-Johansson disease (SLJD) are commonly diagnosed conditions in young, athletic patients who present with anterior knee pain. Despite the familiarity many clinicians have with OSD because of its frequent diagnosis, it does not differ much from SLJD in clinical presentation. Although these diseases generally are self-limiting, diagnostic imaging studies can help clinicians make the correct diagnosis, helping patients avoid progressing to advanced disease states that would require extended rest time, prolonged pain, and potential surgical intervention.

Acute traumatic patellar tendon rupture and simultaneous fracture of the tibial tubercle avulsion in a premature soccer player

Bone-tendon junctions are prone for acute trauma due to its structural weakness, especially in premature males. For the lower limb, the most eminent area is the tibial tubercle apophysis. Osgood Schlatter disease (OSD) due to repetitive trauma or epiphyseal fractures due to one trauma is well described in literature and known in pediatric practice. Traumatic distal patella tendon ruptures on the other hand are a typical injury of the knee extensor mechanism of mature patients in the fourth decade. Here, the very rare condition of fracture of the tibial tubercle apophysis with simultaneous rupture of the distal patellar tendon of a 15 year old soccer player with previous history of OSD is presented including a review of the recent literature.

Методы лечения болезни Осгуда–Шлаттера у детей раннего подросткового возраста в отечественной медицинской практике

Osgood–Schlatter disease is an osteochondropathy of the tibial tuberosity that develops in children aged 12–15 years, more often in boys than in girls (the ratio between them ranges from 3:1 to 7:1), and developes without complications. Recovery occurs in 1–1.5 years from the moment of the first clinical manifestations. It is assumed that the difference is due to the greater participation of boys in sports and risky activities than girls. It was found that the main cause of morbidity is regular exercise and shortening of the rectus femoris muscle in adolescents. For most patients, conservative treatment is effective because painful symptoms stop, but if they persist, surgical treatment is recommended. The study of minimally invasive methods of treating Osgood–Schlatter disease described in the national literature revealed only a few works on various methods of treatment with a description of clinical cases. Objective Review of existing methods of minimally invasive treatment of Osgood–Schlatter disease in children of early adolescence, comparison of their effectiveness from the standpoint of modern evidence requirements. Materials and methods When preparing the review, electronic databases eLibrary, PubMed were used. Results In this review, a comparative analysis of the effectiveness of various minimally invasive methods of treatment is carried out. The main advantages of the methods, as well as their disadvantages, which are due to the complications and difficulties arising from their implementation, are considered. Conclusions The undesirability of surgical treatment of osteochondropathy due to the danger of closing the growth zone is a good reason to develop a new method.

The development of an informative leaflet for children and adolescents suffering from Osgood-Schlatter disease.

The mainstay in the treatment of Osgood-Schlatter Disease (OSD) is guidance on activity modification alongside exercises. The purpose of this study was to create an informative leaflet for patients with OSD, based on evidence and stakeholders perspectives. A synthesis of the literature, including national reference work, clinical research, and systematic reviews informed the initial leaflet. Twelve children with OSD and four clinical experts provided feedback through semi-structured interviews. After incorporating stakeholder input, the leaflet 'Osgood-Schlatter-Information and guidance' was developed. This provides a resource to assist the provision of information and translation of the current evidence.

Efficacy of platelet rich plasma treatment in a young athlete with osgood schlatter disease and patellar tendinopathy, suffering from familiar mediterranean fever A case report

Background Osgood-Schlatter Disease OSD is one of the most common causes of anterior knee pain in children and adolescents. It is a condition with a tendency to self-resolve, and as a result, treatment is symptomatic.

Analysis of Quadriceps Muscle Tightness as a Risk Factor for Osgood-Schlatter Disease: A Prospective Cohort Study.

The prevalence of Osgood-Schlatter disease (OSD) is unknown. Tightness of the quadriceps femoris has been reported to be a risk factor for OSD. Quadriceps muscle tightness would not contribute to the development of OSD. Cohort study; Level of evidence, 2. We enrolled 150 Japanese male junior high school soccer players (N = 300 knees), with a mean age at first examination of 12.5 years (range, 12-13 years). All players were assessed annually and evaluated for 2 years. Ten players (n = 14 knees) had a history of OSD before the first medical examination. After excluding these 10 players (n = 20 knees), the remaining 140 players (n = 280 knees) were included in this prospective analysis. Age at the time of starting soccer, history of injury (including OSD and time missed), height, weight, annual increase in height, body mass index (BMI), straight-leg raise angle, heel-buttock distance (HBD), and ultrasound images of the tibial tuberosity (maturity and morphology) were compared between players who developed OSD and those who did not. OSD was identified in 8 knees of 6 players, with an incidence of 2.9% of knees (8/280) and 4.3% of players (6/140). Univariate analysis revealed significant differences between the OSD and non-OSD groups regarding BMI (17.1 ± 1 kg/m2 vs 18.5 ± 1.6 kg/m2, respectively; P = .018), HBD (1.5 ± 1.6 cm vs 4.8 ± 4.5 cm; P < .001), and stage of tibial tuberosity maturity (P < .001). The maturity of the tibial tuberosity was the only independent risk factor for the development of OSD in multivariate logistic regression analysis (odds ratio, 9.848 [95% CI, 3.297-29.41]; P < .001). Study findings indicated that quadriceps muscle tightness did not contribute to the development of OSD.

Do adolescents with Osgood-Schlatter display nociplastic pain manifestations compared to controls: A cross-sectional study.

Osgood-Schlatter disease is an overuse musculoskeletal pain condition. The pain mechanism is considered nociceptive, but no studies have investigated nociplastic manifestations. This study investigated pain sensitivity and inhibition evaluated through exercise-induced hypoalgesia in adolescents with and without Osgood-Schlatter. Cross-sectional study. Adolescents underwent a baseline assessment comprising clinical history, demographics, sports participation, and pain severity rated (0-10) during a 45-second anterior knee pain provocation test, consisting of an isometric single leg squat. Pressure pain thresholds were assessed bilaterally at the quadriceps, tibialis anterior muscle, and the patella tendon before and after a three-minute wall squat. Forty-nine adolescents (27 Osgood-Schlatter, 22 controls) were included. There were no differences in the exercise-induced hypoalgesia effect between Osgood-Schlatter and controls. Overall, an exercise-induced hypoalgesia effect was detected at the tendon only in both groups with a 48 kPa (95 % confidence interval 14 to 82) increase in pressure pain thresholds from before to after exercise. Controls had higher pressure pain thresholds at the patellar tendon (mean difference 184 kPa 95 % confidence interval 55 to 313), tibialis anterior (mean difference 139 kPa 95 % confidence interval 24 to 254), and rectus femoris (mean difference 149 kPa 95 % confidence interval 33 to 265). Higher anterior knee pain provocation severity was associated with lower exercise-induced hypoalgesia at the tendon (Pearson correlation = 0.48; p = 0.011) in participants with Osgood-Schlatter. Adolescents with Osgood-Schlatter display increased pain sensitivity locally, proximally, and distally but similar endogenous pain modulation compared to healthy controls. Greater Osgood-Schlatter severity appears to be associated with less efficient pain inhibition during the exercise-induced hypoalgesia paradigm.

Poster 361: Prolotherapy in the Treatment of Sports-Related Tendinopathies: A Systematic Review

Objectives: Prolotherapy (PrT) involves the injection of a proliferant in order to irritate a microenvironment and promote healing via the inflammatory cascade. PrT has become an increasingly popular nonoperative treatment in orthopedics. However, numerous prolotherapy solutions exist and varying applications and results have been described. The purpose of this study is to review high-quality randomized controlled trials (RCTs) that analyzed efficacy and safety profiles of prolotherapy (PrT) treatments for the most common sports-related tendinopathies. Methods: All RCTs published in English between January 1st 1980 and July 30th 2021, reported in Embase, Medline, and Web of Science databases, were queried with search terms including sclerotherapy, prolotherapy, sports medicine, sports injuries, tendinopathies, and musculoskeletal pain/injuries. PRISMA guidelines were used. Studies analyzing tendinopathies using a RCT design were included, while case controls, reviews, and observational studies were excluded. Duplicates were eliminated through Endnote. The remaining articles were screened by titles, followed by abstract and then by full text analysis. The Cochrane collaboration tool was used to assess for risk of bias. Two researchers independently performed the screening and conflicts were resolved using Rayyan © software (Rayyan Systems Inc., Cambridge, MA, USA). Graphical representations were created using SPSS version 28.00. Results: Application of the inclusion and exclusion criteria yielded 20 RCTs (fig. 1): 6 studies on lateral epicondylitis (LE); 6 on rotator cuff tendinopathy (RC); 5 on plantar fasciitis (PF); 2 on Osgood-Schlatter disease (OSD); 1 on Achilles tendinosis. Most of the trials used dextrose injections over P2G or hypertonic glucose (fig. 2), and the most common studied conditions were LE and RC (fig.3). The average follow-up period was 12 weeks. No significant adverse effects were reported, and the most common outcome measures were visual analog scale (VAS), patient rated tennis elbow evaluation (PRTEE), quick- disabilities of the arm, shoulder, and hand (Q-DASH), and symptoms relief. For the treatment of LE, dextrose PrT was associated with significant improvement in VAS pain score at rest and PRTEE compared to normal saline (p&lt;0.041, p&lt;0.013 respectively). Additionally, compared to hyaluronic acid and lifestyle modifications, PrT showed significant improvement in VAS pain score with activity, Q-DASH, and PRTEE scores (p&lt;0.04, p&lt;0.04, p&lt;0.05 respectively). For the treatment of RC, dextrose PrT was found superior to physiotherapy in the shoulder disability index (p&lt;0.001). Finally, dextrose PrT demonstrated significant improvements in foot function index (p&lt;0.001) for the treatment of PF, and reduction of symptoms in OSD (p&lt;0.024) compared to physical therapy and lidocaine controls. Patients with AT had a more rapid improvement in symptoms in the combined PrT/eccentric loading exercises protocols compared to dextrose PrT alone (p&lt;0.007). A graphical representation of the results is reported in figure 4. Conclusions: This systematic review summarized high quality RCTs and found PrT injections to be overall safe and effective in the treatment of sports-related tendinopathies. Further RCTs with larger sample sizes and comparisons to orthobiologics would add to the literature. Based on the current findings, sports medicine professionals may safely pursue PrT as an additional component of conservative treatment before surgery.
