RESUMEN

Background: In addition to other variables associated with PRP injections for Knee Osteoarthritis (OA), some confusion exists about the role of exogenous activators. The current study looks at matched groups getting PRP injections with or without activator (Calcium gluconate) in early knee OA patients. Methods: Patients of early OA knee meeting inclusion criteria were randomly divided into 2 groups; Group A (43 patients) received 8 ml PRP injection alone, and Group B (48 patients) received 8 ml PRP along with 2 ml Calcium gluconate as activator. The patients were evaluated at baseline, 6 weeks, 3 months and 6 months for WOMAC Pain and Total WOMAC scores; secondary variables assessed were VAS score and patient satisfaction. Results: The baseline characteristics of both groups were comparable. Leucocyte-depleted PRP with 5 times concentration and average absolute platelet numbers of 7.144 billion per knee was injected. Mean Pain WOMAC scores decreased in both groups from baseline (group A-8.68, group B-9.09) to final follow-up (group A-4.67, group B-5.11). Similarly, Mean Total WOMAC scores decreased from baseline (group A-37.81, group B-37.41) to (group A-21, group B-21.36) at the final follow-up in both groups. There was no significant difference between both groups, and both showed similar trends. Similar findings were noted for VAS scores. Patient satisfaction was also not different (group A, 90.69%, group B, 89.58%) at the end of 6 months. Conclusion: Our study concluded doubtful role of adding exogenous activator to PRP preparation.

RESUMEN

Purpose of the Study: The evaluation of anti-apoptotic and chondroprotective properties of a single injection of PRP using immunohistochemistry (IHC). Methods: This was a placebo-controlled blinded experimental study. Ten healthy Dunkin Hartley guinea pigs were selected. One knee of each animal was injected with a single injection of PRP (Group A); the contralateral knee acted as a control and was injected with a single injection of normal saline (Group B). These groups were further divided into A3 and B3 based on the timeline of animal sacrifice (3 months) and A6 and B6 (6 months). The formalin-preserved articular cartilage blocks were subjected to IHC to stain Aggrecan, Caspase-3, and Collagen-2. Results: The mean IHC score was significantly low for Caspase-3 (p-0.029) in intervention group (A3) in comparison to placebo control group (B3) pointing towards decreased apoptosis. The mean IHC values were significantly higher for Collagen II (p-0.011) for intervention group (A6) in contrast to control group (B6); values were also significantly low for Caspase-3 (p-0.029) in A6 as compared to B6. The mean Caspase-3 values were significantly higher in A6 as compared to A3 (p-0.029). Conclusion: The impact of a solitary injection of PRP on upregulation of anabolic pathways inside cartilage is relatively slower as compared to its effect on downregulation of apoptotic pathways. Even a single PRP injection holds the potential to change cartilage microenvironment, but the effects are not long lasting.

RESUMEN

Background: It is well known that the implementation of the WHO surgical safety checklist (SSC) leads to improved operating room team coordination and reduced perioperative complication and mortality rates. Although it is proven to be beneficial worldwide, its awareness and usage need to be evaluated in a diverse country like India. As orthopaedic surgeries involve implants and tourniquet usage, it is important to evaluate the applicability of WHO SSC specifically to orthopaedic surgeries, and whether any modifications are needed. Materials and Methods: A web-based cross-sectional survey was conducted among Indian Orthopaedic Surgeons with a pre-defined questionnaire regarding awareness, usage and suggestions to modify the existing WHO SSC (2009) for orthopaedic surgeries. Results: 513 responses were included for final analysis. 90.3% of surgeons were aware of the surgical safety checklist; however, only 55.8% used it routinely in their practice. The awareness of SSC availability was 1.85 times more among younger surgeons (< 20 years of experience) than among those with > 20 years of experience. 17% of surgeons thought the usage of SSC was time-consuming and 52.4% of participants felt a need to modify the existing WHO SSC (2009) for orthopaedic surgeries. 34.5% recommended the inclusion of the patient blood group in the "Sign-in" section, 62.77% proposed the inclusion of details about the tourniquet, whereas only 6.63% suggested adding about surgical implant readiness in the "Time-out" section and 72.7% suggested including a check to make sure the tourniquet was deflated, removed and also recording of the total usage time during the "Sign-out" section. Conclusion: Despite high (90%) awareness among Indian Orthopaedic surgeons, they have limited usage of the WHO SSC in their practice. Identifying barriers and considering modifications for orthopaedic surgeries, like details about tourniquet usage during the "Time-out" section and a check to ensure it was removed during the "Sign-out" section, will improve patient safety and outcomes.

RESUMEN

BACKGROUND: Clinical outcomes after fixation of distal humerus intraarticular fractures are directly related to the quality of reduction. The use of three-dimensional (3D)-printed fracture models can benefit preoperative planning to ensure good reduction. This review aims to determine if surgery performed with 3D printing assistance are faster and result in fewer complications and improved clinical outcomes than conventional methods. We also outline the benefits and drawbacks of this novel technique in surgical management of distal humerus fractures. METHODS: A systematic literature search was carried out in various electronic databases. Search results were screened based on title and abstract. Data from eligible studies were extracted into spreadsheets. Meta-analysis was performed using appropriate computer software. RESULTS: Three randomized controlled trials with 144 cases were included in the final analysis. The 3D-printed group had significantly shorter mean operating time (mean difference, 16.25 minutes; 95% confidence interval [CI], 12.74-19.76 minutes; P<0.001) and mean intraoperative blood loss (30.40 mL; 95% CI, 10.45-60.36 mL; P=0.005) compared with the conventional group. The 3D-printed group also tended to have fewer complications and a better likelihood of good or excellent outcomes as per the Mayo elbow performance score, but this did not reach statistical significance. CONCLUSIONS: Three-dimensional-printing-assisted surgery in distal humerus fractures has several benefits in reduced operating time and lower blood loss, indirectly decreasing other complications such as infection and anemia-related issues. Future good-quality studies are required to conclusively demonstrate the benefits of 3D printing in improving clinical outcomes. Level of evidence: I.

RESUMEN

BACKGROUND: The Chaput fragment, a bony avulsion of the anterolateral margin of the distal tibia, is a less commonly discussed fracture pattern in ankle injuries. Its significance in ankle fractures and the optimal fixation technique remains unclear due to limited literature. This study aims to describe the morphology of ankle fractures with Chaput fragment and introduce a new classification system. MATERIALS AND METHODS: We retrospectively analyzed 33 patients with ankle fractures with associated Chaput fragment treated at our institute over a 3-year period. Data on patient demographics, fracture classification, surgical approach, and fixation method were collected, and a novel classification system for Chaput fragments was proposed. RESULTS: Four distinct morphological types of Chaput fragment were identified (types 1-4), and three newer variants of trimalleolar fractures were identified (anterior, lateral, and medial variants). Type 1 refers to a small avulsion fragment attached to the anterior-inferior tibiofibular ligament; Type 2 is an anterolateral oblique type; Type 3 refers to an anterolateral fragment with extension into the medial malleolus and Type 4 is a comminuted Chaput fragment. Type 1 Chaput fragment was the most prevalent (60.6%), followed by Type 2 (24.3%), Type 4 (9.1%), and Type 3 (6.1%). The fixation methods ranged from screw fixation, plate fixation, and suture fixation to combinations of these techniques or even indirect stabilization with syndesmotic screws. CONCLUSION: Our new classification system based on morphology includes all possible variants of Chaput fracture. This preliminary data needs to be corroborated by more studies and validated by a larger number of observers.

RESUMEN

Background: Confusion persists regarding the ideal dosage of platelet-rich plasma (PRP) injection for knee osteoarthritis (OA). Purpose/Hypothesis: The purpose of the study was to compare the efficacy of 2 different single-injection PRP dosages in patients with early knee OA-a conventional 4 mL dose and a superdose of 8 mL. It was hypothesized that 8 mL of PRP would be superior to 4 mL of PRP in this patient population. Study Design: Randomized clinical trial; Level of evidence, 1. Methods: Patients with early knee OA (Kellgren-Lawrence grades 1 and 2) who met the inclusion criteria were randomly divided into 2 groups: Group A (n = 50 knees) received a 4-mL PRP injection, and group B (n = 49 knees) received an 8-mL PRP injection, both prepared using the same procedure. Patients were evaluated at the baseline, 6 weeks, 3 months, and 6 months using the Western Ontario and McMaster Universities Arthritis Index (WOMAC), the WOMAC-Pain subscale, the visual analog scale for pain, the Knee injury and Osteoarthritis Outcome Score, and patient satisfaction, and results were compared between the groups. Results: The baseline characteristics of the 2 groups were comparable (group A: mean age, 51.96 ± 6.93 years; group B: mean age, 49.12 ± 9.8 3 years). Leucocyte-depleted PRP with 3.5 times concentration (final product platelet concentration, 706.74 × 103-µL) was injected. The mean absolute platelet count injected was 2.82 ± 0.0012 billion in group A and 5.65 ± 0.0022 billion in group B. All patient-reported outcome scores improved significantly in both groups from the baseline to the final follow-up (P < .001), with overall trends and results significantly better in group B than in group A (P < .001). Patient satisfaction at the 6-month follow-up was also better in group B (96%) compared with group A (68%). Short (2 to 7 days) self-limiting complications, such as pain and stiffness, occurred more often in group B (P < .001). Conclusion: Patients with early knee OA had significantly better improvement in pain and function when treated with an 8-mL injection of PRP compared with a 4-mL injection of PRP. The larger dose of PRP had approximately twice the number of platelets. Registration: CTRI/2020/02/023403 (Clinical Trials Registry-India identifier).

RESUMEN

SETTING: Diagnosing osteoarticular tuberculosis (OATB) and detecting drug resistance is a challenge in an endemic country like India. OBJECTIVE: Truenat MTB Plus assay (TruPlus), a chip-based portable machine, was compared with GeneXpert Ultra (GxUltra) for diagnosing drug-resistant OATB. DESIGN: 115 synovial fluid and pus specimens [22 culture-positive confirmed, 58 culture-negative clinically-suspected, 35 non-TB controls] processed between 2017 and 2023 were subjected to TruPlus, GxUltra and multiplex-PCR for diagnosing OATB. They were further screened for rifampicin resistance using TruRif chip. The performance was evaluated against composite reference standard, phenotypic drug susceptibility testing and rpoB gene sequencing. RESULTS: TruPlus, GxUltra and MPCR detected 77.5 %, 71.25 %, and 83.75 %, cases of OATB, respectively. TruPlus detected five additional cases missed by GxUltra. The performance of TruPlus was comparable to GxUltra (p = 0.074) and to MPCR (p = 0.074), while performance of GxUltra was significantly inferior to MPCR (p = 0.004). The overall agreement with reference standard was substantial for TruPlus and MPCR and moderate for GxUltra. Both TruRif and GxUltra reported 4 cases as rifampicin resistant. CONCLUSION: TruPlus along with TruRif offers better sensitivity than GxUltra. Its compact and portable platform allows wider application in peripheral settings, thus making it a pragmatic solution for diagnosing OATB and its drug resistance.

RESUMEN

Purpose: Graft rupture is the most prevalent complication following pediatric anterior cruciate ligament reconstruction (ACLR). The hamstring tendon (HT) autograft is frequently employed, while the quadriceps tendon (QT) autograft has garnered increased attention recently. This study aims to perform a systematic review to assess the complication rates and functional outcomes associated with these two widely used autografts in skeletally immature patients - comparing HT versus QT autografts. Research question: Is QT autograft better than HT autograft for ACLR in skeletally immature cohorts? Methodology: Three electronic databases (PubMed/Medline, Scopus, and Ovid) were comprehensively searched to identify pertinent articles reporting the outcomes of HT and QT autografts in pediatric ACLR with a minimum 2-year follow-up. Data on the outcome parameters, such as graft rupture rates, contralateral ACL injury rates, functional outcomes, and growth disturbances rates, were extracted. Meta-analysis was performed using OpenMeta Analyst software. Results: Twelve studies were included for meta-analysis (pooled analysis) with 659 patients (QT: 205; HT: 454). The analysis showed that QT autografts had a significantly lesser graft rupture rate than HT autografts (3.5 % [95 % CI 0.2, 6.8] and 12.4 % [95 % CI 6.1, 18.7] respectively, p < 0.001). The graft rupture rates between QT with bone and without bone block showed no statistically significant difference (4.6 % [95 % CI 0.8, 1.0] and 3.5 % [95 % CI 2.0, 8.9] respectively, p = 0.181). The overall contralateral ACL injury rate was 10.2 %, and the subgroup analysis revealed no statistically significant difference between the QT and HT groups (p = 0.7). Regarding functional outcome scores at the final follow-up, the mean Lysholm score demonstrated a significant increase in the QT group compared to the HT group (p < 0.001). There were no significant differences between the two groups concerning growth disturbances at the final follow-up. Return to sports (RTS) varied between 6 and 13.5 months after surgery. Conclusion: QT autografts demonstrate encouraging outcomes, showcasing lower graft rupture rates, better functional outcomes, and comparable contralateral ACL injury rates and growth disturbances relative to the commonly used HT autograft in skeletally immature patients undergoing ACLR.

RESUMEN

PURPOSE: A locking plate (LP) or non-locking plate (NLP) can be used for distal fibula fracture fixation. However, the advantages of LP over NLP in patients with distal fibula fractures are not clear. In terms of indications, the role of the two plates probably differs; however, to draw comparative conclusions, we conceptualized this systematic review and meta-analysis of studies that directly compared the two plates, wherein both groups' indications and baseline parameters were similar. METHODS: An electronic literature search was performed using PubMed/Medline, Embase, Scopus, and Cochrane Library databases for studies comparing the LP versus NLP fixation for the lateral malleolus fracture. A total of 18 studies were included in qualitative and quantitative analysis. A subgroup analysis was performed for patients aged < 55 years and patients aged > 55 years. The statistical analysis was performed by Review Manager Software version 5.4.1. RESULTS: A meta-analysis of 4243 fractures was performed across 18 studies. The rate of fracture union and overall complication rates did not differ between the two fixation groups with an OR of 0.71 (95% CI 0.26, 1.96, p = 0.51 and 1.11 (95% CI 0.84, 1.47, p = 0.47, respectively. There is no difference in the reoperation rate due to minor or major complications between the two groups. There was no difference in functional outcome (MD -0.85, with 95% CI -5.63, 3.93, p = 0.73), but NLP has a shorter surgical duration (MD 3.0, with 95% CI 0.26, 5.75, p = 0.03). A leave-one-out sensitivity analysis performed for overall complications affected the final outcome of the meta-analysis. CONCLUSION: This meta-analysis demonstrates no clear benefit in selecting LP over NLP for the fixation of lateral malleolus fractures.

RESUMEN

Background: Amputation of a limb is equivalent to loss of a person's life. Psychological aspects are essential factors in dealing with the disability and functional outcome is a significant concern. Longitudinal studies have not examined the experience and determinants of common mental health problems and functional outcome in lower limb amputees. Materials and Methodology: A total of 103 lower limb amputees were recruited and followed up for 6  months. Patients were assessed on Hospital Anxiety and Depression Scale (HADS) and Social Functioning (SF-36) Quality of life, semi-structured clinical interview for psychiatric disorders and phantom limb at baseline (in hospital), at 2 weeks, 3 months and 6 months, respectively after discharge. Holistic care was provided through psychological counselling, supportive sessions, medications if required, rehabilitation counselling, prosthesis implantation, and treatment as usual. Results: Holistic care resulted in a statistically significant reduction in anxiety, depression and overall psychiatric morbidity as measured on HADS (p < 0.001). There was a significant improvement in all the domains of SF-36 (p -< 0.001) except the role of limitation due to physical activity. The intervention also resulted in a statistically significant reduction in the presence of phantom limbs. Conclusion: Amputees should be provided holistic care under one roof, which was found to be very useful in treating psychiatric morbidity, social functioning and quality of life.

RESUMEN

Background: An increase in the on-field intensity in modern cricket, results in an increased number of player injuries. Integration and easy access to professional physiotherapy, technology, rehab protocols, and mental/physical conditioning aid in early return to sports in the injured; however, at the grassroots, these facilities may not be available with untrained support staff and limited funds. Injuries can go unnoticed and, therefore, there is a need for an easy process of identification and documentation of such injuries. We devised a questionnaire-based survey to evaluate its effectiveness at the junior level of professional cricket. Materials and Methods: An Online self-administered questionnaire was prepared and the link was given to active Union Territory Cricket Academy (UTCA), Chandigarh, cricketers of any gender between 15 and 35 years of age, through different online platforms like WhatsApp, Telegram and emails, for the submission of their responses. Results: The questionnaire was administered to 98 participants out of which 77 participants' responses were evaluated (41 males and 36 females). 74/77 participants were below 30 years of age. There were 18 wicketkeepers, 33 bowlers and 26 batsmen as per their major role in the team. 37/77 cricketers (20 males, 17 females) had injuries during the previous 2 years; this included 17 bowlers, 11 batsmen and 9 wicketkeepers. The most common body part injured in the survey were fingers (12) followed by the back (7). The amount of training time lost, reported in the survey ranged from a week up to 1 year. Conclusion: Online surveys could be the first step to accumulating data and making initial player profiles, starting even at junior levels of cricket. Further detailed evaluations may be performed after this, and coaches and administrators could potentially profile cricket injuries and identify chronic issues. Supplementary Information: The online version contains supplementary material available at 10.1007/s43465-023-00995-3.

RESUMEN

Purpose: The aim of this study was to determine the ideal forearm position that allows maximum upper-limb function. In certain congenital/acquired upper-limb disorders, the management boils down to sacrificing rotatory movements of the forearm. The position of fusion that facilitates maximum upper-limb function is a topic of debate and is decided upon by personal preferences and assumptions. Although the literature has many level five evidence reports, there is a lack of well-designed research to answer the same question and we intended to study it both in dominant and non-dominant limbs. Methods: 15 healthy adolescent volunteers were fitted with a custom adjustable brace that simulated forearm arthrodesis in five rotatory positions. They were asked to carry out a series of activities as per Sollerman's hand function test, and each activity was scored using the standardized scoring system. The test was carried out with the brace fitted first in the dominant side, followed by the non-dominant side, and finally in both the upper limbs together. Results: We found that the mid-prone position allowed for the best function overall in both dominant and non-dominant upper limbs, and if both upper limbs required simultaneous fusion, our results suggest that fixing the dominant side in mid-prone and non-dominant side in 45° supination would be ideal. Conclusions: For unilateral forearm arthrodesis, the ideal position of fusion is the same irrespective of the dominance of the limb, whereas, for bilateral arthrodesis, limb dominance is to be taken into consideration. Level of Evidence: Level III quasi-experimental study.

RESUMEN

Background: Musculoskeletal infections are a major source of morbidity for orthopedic and trauma patients, are associated with prolonged treatment times, and, unfortunately, suffer from poor functional outcomes. Further complicating the issue, antimicrobial resistance (AMR) is increasingly impacting the treatment of musculoskeletal infections with a diminishing repertoire of effective antibiotic agents for some highly resistant pathogens. Most orthopedic surgical procedures involve implants, and the formation of bacterial biofilms on these implants is now recognized as a major factor contributing to the failure of antibiotic therapy in orthopedic surgery. Methods: This review presents an overview of the types, structure, formation, and pathogenesis of biofilms as they pertain to musculoskeletal infections. Furthermore, it describes the key concepts in the management of biofilms and future perspectives for the better treatment of patients with biofilm-related musculoskeletal infections. Results: A bacterial biofilm is a dynamic, living conglomerate of bacteria encased in an extracapsular polysaccharide matrix (EPS). Biofilms are a natural mode of survival for virtually all bacterial species, including both Grampositive and Gram-negative bacteria, as well as fungi. The biofilm model of growth confers resistance by several well-defined mechanisms regardless of the species of the microorganism. In most cases, biofilm management often necessitates radical measures to ensure eradication including both surgical and medical interventions. Conclusions: Orthopedic surgeons should be aware of the key concepts pertaining to biofilms, and the impact that these can have on clinical practice.

RESUMEN

The study evaluated real-time quantitative polymerase chain reaction (qPCR) and high-resolution melt-curve analysis (HRM) for simultaneous diagnosis of osteo-articular tuberculosis (OATB) and drug resistance. Two hundred and fifty synovial fluid and pus specimens (20 confirmed OATB by culture, 130 suspected OATB, and 100 controls) processed in the Department of Medical Microbiology, PGIMER were subjected to qPCR using rpoB, MPB64, and IS6110 genes. All OATB positive specimens were subjected to HRM for detecting resistance to rifampicin and isoniazid. qPCR detected 129/150 OATB cases with a sensitivity of 86% (95% for confirmed and 84.6% for suspected OATB cases) and specificity of 100%. rpoB and MPB64 genes had higher sensitivity than IS6110 (86% vs. 74.6%). HRM reported eight multidrug resistant (MDR), two mono-rifampicin, and five mono-isoniazid resistant cases, all were concordant with gene sequencing. qPCR followed by HRM analysis offer a simple, accurate, and rapid platform for simultaneous detection of OATB and MDR.

RESUMEN

OBJECTIVES: Bone tuberculosis (TB) is the third most common types of extrapulmonary tuberculosis. It is critical to understand mycobacterial adaptive strategies within bone lesions to identify mycobacterial factors that may have role in disease pathogenesis. METHODS: Whole genome microarray was used to characterize the in-vivo transcriptome of Mycobacterium tuberculosis (M.tb) within bone TB specimens. Mycobacterial virulent proteins were identified by bioinformatic software. An in vitro osteoblast cell line model was used to study the role of these proteins in bone TB pathogenesis. RESULTS: 914 mycobacterial genes were significantly overexpressed and 1688 were repressed in bone TB specimens. Pathway analysis of differentially expressed genes demonstrated a non-replicative and hypometabolic state of M.tb, reinforcement of the mycobacterial cell wall and induction of DNA damage repair responses, suggesting possible survival strategies of M.tb within bone. Bioinformatics mining of microarray data led to identification of five virulence proteins. The genes encoding these proteins were also upregulated in the in vitro MC3T3 osteoblast cell line model of bone TB. Further, exposure of osteoblast cells to two of these virulence proteins (Rv1046c and Rv3663c) significantly inhibited osteoblast differentiation. CONCLUSION: M.tb alters its transcriptome to establish infection in bone by upregulating certain virulence genes which play a key role in disturbing bone homeostasis.

RESUMEN

BACKGROUND: Intracapsular femoral neck fractures are challenging to treat, with outcomes depending on the quality of reduction, and the stability of fixation. Cannulated cancellous screws (CCS) are the most commonly used implants to fix these fractures, but failure rates are significant. The recently introduced femoral neck system (FNS) may be a better option than CCS fixation and this review attempts to compare the results. METHODS: Four electronic databases were searched for eligible articles that had comparative data on the outcomes of fixation of adult femoral neck fractures with FNS and CCS. Data on various outcome parameters were collected. Meta-analysis was conducted using a random-effects model with 95% confidence intervals. RESULTS: Eight studies with 509 cases having a mean age of 50.8 years were included for final analysis. FNS was found to be associated with significantly reduced complication rates (p < 0.001), decreased incidence of postoperative femoral neck shortening (p < 0.001), quicker time to fracture union (p = 0.002), and better functional outcome scores (p < 0.001) compared to cannulated screws. FNS was also associated with a shorter operating time (mean difference 6.65 min) although not statistically significant (p = 0.24). CCS group had significantly reduced mean blood loss (p < 0.001). CONCLUSION: The available literature supports FNS as a better option for adult femoral neck fractures, with a lower complication rate, quicker union, and better clinical outcomes. LEVEL OF EVIDENCE: Level 3.

RESUMEN

Background/Purpose: Since badminton has emerged as a frequently played non-contact recreational sport in India, it is essential to document the injury patterns and incidence. However, there is no existing literature on this topic among Indian players. Materials and Methods: A web-based questionnaire was circulated among recreational badminton players across North India, enquiring about demographic details, injury characteristics, and factors associated with an injury like BMI, warm-up practice, and physical training. Results: Data of 237 eligible participants revealed an injury incidence rate of 57.1%. The ankle and dominant-side shoulder were the most common anatomical regions affected. The most common injury types were ligament sprain and muscle/tendon strain. Factors like age, frequency, duration of play, type of footwear, BMI, prior warm-up, court surface, and physical training were significantly associated with injury incidence on univariate logistic regression analysis. On multivariate logistic regression analysis, we found male gender, a lack of prior warm-up, inadequate physical training, and age group between 26 and 30 years to be four independent risk factors for injury. Conclusion: The recreational badminton player of India had a relatively higher incidence of injury compared with the limited published data from other countries. Modifiable factors like a proper warm-up before the game, regular physical fitness training, and injury awareness programs can reduce the injury rates.

RESUMEN

BACKGROUND: Trimalleolar fractures are generally considered to have inferior outcomes among ankle injuries. Historically, emphasis was placed on the size of the posterior malleolar fracture (PMF) to guide surgical decision-making and predict outcomes. Recent studies have suggested that the morphology of the PMF fragment is more important than its size. The aim of this systematic review was to determine if the outcomes of trimalleolar fractures depend on the morphology of the PMF as per the Haraguchi classification system after surgical fixation. METHODS: A systematic literature search was conducted in the electronic databases of PubMed, Embase, Scopus, and Ovid. Title and abstracts were screened, and data from eligible studies were extracted. Meta-regression and pooled analysis was performed using appropriate computer software. RESULTS: 11 studies with 597 patients were included in the final analysis. Pooled mean AOFAS score was 87.43 (95% CI 84.24-90.62) after a mean follow-up of 31.6 months. Univariate and multivariate meta-regression analysis demonstrated that as the percentage of Haraguchi type 1 patients increased, there was a statistically significant improvement in outcome scores. A similar trend was noted for Haraguchi type 3 fractures, and a reverse trend was observed for Haraguchi type 2 injuries, although neither were statistically significant. CONCLUSION: Our review suggests that the outcomes of trimalleolar fractures after surgical fixation may depend on the morphology of the PMF, with Haraguchi type 1 fractures having overall superior functional outcomes than Haraguchi type 2 and 3 injuries. Future studies need to done to conclusively prove or refute these findings.
