Centralization reduces meniscal extrusion, improves joint mechanics and functional outcomes in patients undergoing meniscus surgery: A systematic review and meta-analysis.

PURPOSE: To perform a systematic review and meta-analysis of the existing literature on meniscal centralisation procedures, analysing its impact on meniscal extrusion, joint biomechanics and clinical and radiological outcome measures. METHODS: The Cochrane Controlled Register of Trials, PubMed (MEDLINE) and Embase were used to perform a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Biomechanical studies on healthy animal or human cadaveric knee joints that assessed meniscal extrusion or tibiofemoral contact mechanics (contact area and pressure) following centralization for meniscal pathologies were included. For clinical studies, those that prospectively or retrospectively assessed patient-reported outcome measures (PROMs), postoperative knee motion, complications and radiological extrusion following centralization for meniscal pathologies were included. RESULTS: Fifteen studies were included in the analysis, comprising eight biomechanical, six clinical and one both. There were 92 knee specimens for biomechanical testing, of which 40 were human cadaveric and 52 porcine models. Biomechanical data revealed centralization to be commonly performed for posterior meniscal root tears and significantly reduced extrusion and contact pressure whilst improving contact area following a tear (p < 0.00001). Centralization restored extrusion to that of the native knee at all flexion angles described (0-90°, p = 0.25) and, compared to the torn state, brought tibiofemoral contact mechanics 3.2-5.0 times closer to the native state. Clinical data showed that 158 patients underwent centralization for extrusion. It improved postoperative Knee Injury and Osteoarthritis Outcome score (KOOS) (p = 0.006) and Lysholm scores (p < 0.00001) at 25.0 months, maintained extrusion reduction at 17.1 months (p < 0.00001) and preserved knee motion. CONCLUSION: Centralisation for various meniscal injuries associated with extrusion can reduce meniscal extrusion and improve joint biomechanics, along with clinical and radiological outcomes. Existing evidence is still scarce and exhibits a notable amount of methodological heterogeneity. LEVEL OF EVIDENCE: Systematic review of Level IV evidence.

A Comparative Study of Mini-Scarf Versus Standard Scarf Osteotomy for Hallux Valgus Correction.

Scarf osteotomy is widely used for hallux valgus treatment. More recently, a trend has begun toward the use of minimally invasive techniques, including the mini-scarf osteotomy, in which the diaphyseal cut is shortened. We compared the mini-scarf and traditional scarf osteotomy to determine whether the mini-scarf osteotomy is as effective as the scarf osteotomy in correcting mild to moderate hallux valgus and improving clinical function. We reviewed the cases of 37 consecutive patients during a 2-year period. A total of 21 (56.8%) patients had undergone scarf osteotomy and 16 (43.2%) had undergone mini-scarf osteotomy. The intermetatarsal, hallux valgus, and distal metatarsal articular angles and medial sesamoid position of the 2 groups were measured at 12 weeks postoperatively. The Manchester Oxford Foot Questionnaire scores and patient satisfaction were recorded at 28 months postoperatively. All radiologic parameters and Manchester Oxford Foot Questionnaire scores had significantly improved in both groups (p < .05 and p < .01 for mini-scarf and scarf, respectively). The medial sesamoid position had improved in all patients, with similar satisfaction between the 2 procedures (p = .43). The results of the present study have shown that the mini-scarf osteotomy for mild to moderate hallux valgus is as effective as the standard approach, with the potential benefit of a smaller scar and less soft tissue disruption.

A systematic review and network meta-analysis of outcomes after total wrist arthroplasty in inflammatory and non-inflammatory arthritis.

This systematic review analysed the available evidence on the clinical outcomes of total wrist arthroplasty (TWA) in patients with inflammatory and non-inflammatory arthritis. After screening, 12 studies met the inclusion criteria. They involved 359 patients with 378 TWA implants. The results showed that TWA significantly improved Disabilities of the Arm, Shoulder and Hand (DASH)/Quick-DASH scores and pain visual analogue scale scores in both arthritis groups compared with preoperative values. However, there was no statistically significant difference in the outcome scores between the two groups. Three studies reported Patient-Rated Wrist Evaluation (PRWE) scores, and TWA significantly improved PRWE scores in non-inflammatory arthritis but not in inflammatory arthritis, with no significant difference in postoperative outcome scores between the two groups. Although the included studies have limitations, the review suggests that TWA may be a successful treatment for wrist pain in individuals with either inflammatory or non-inflammatory arthritis. However, further high-quality trials are needed to confirm these findings.

The Role of Anterolateral Ligament Reconstruction or Lateral Extra-articular Tenodesis for Revision Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis of Comparative Clinical Studies.

BACKGROUND: After its success in restoring rotational stability and reducing failure rates in primary anterior cruciate ligament reconstruction (ACLR), lateral extra-articular tenodesis (LET) or anterolateral ligament reconstruction (ALLR) has been endorsed for use in revision ACLR surgery, where failure rates are historically higher. PURPOSE: To perform a systematic review and meta-analysis on whether the addition of a LET or ALLR results in superior clinical outcomes and stability compared with isolated revision ACLR (iACLR). STUDY DESIGN: Meta-analysis; Level of evidence, 4. METHODS: The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review and meta-analysis of comparative studies using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: ("extra-articular" OR "tenodesis" OR "anterolateral ligament" OR "iliotibial") AND ("anterior cruciate ligament") AND ("revision" OR "re-operation"). Data pertaining to all patient-reported outcome measures (PROMs), rotational stability, and postoperative complications were extracted from each study. RESULTS: After abstract and full-text screening, 10 clinical comparative studies were included. There were 793 patients, of whom 390 had an iACLR while 403 had an ACLR augmented with a LET or an ALLR (augmented ACLR [aACLR]). The mean time for assessment of PROMs was 35 months. The aACLR group had superior International Knee Documentation Committee (IKDC) scores (standardized mean difference [SMD], 0.27; 95% CI, 0.01 to 0.54; P = .04), rotational stability (odds ratio [OR], 2.77; 95% CI, 1.91 to 4.01; P < .00001), and lower side-to-side difference (OR, -0.53; 95% CI, -0.81 to -0.24; P = .0003) than those without the augmentation. Furthermore, they were less likely to fail (OR, 0.44; 95% CI, 0.24 to 0.80; P = .007). Subgroup analysis in the higher-grade laxity cohort (grade ≥2) revealed an even greater IKDC score (SMD, 0.51; 95% CI, 0.16 to 0.86; P = .005) and an improved Lysholm score (SMD, 0.45; 95% CI, 0.24 to 0.67; P < .0001) in the aACLR group. CONCLUSION: Revision aACLR with a LET or an ALLR can improve subjective IKDC scores, restore rotational stability, and reduce failure rates compared with iACLR. Although controversy remains on the necessity of augmenting all revision ACLRs, the present meta-analysis advocates adding a lateral procedure, particularly in those with a higher-grade pivot shift.

Modified Mason-Allen vs Two Simple Stitch Fixation for Medial Meniscus Posterior Root Tears: A Systematic Review and Meta-analysis.

BACKGROUND: Various suture configurations are available for medial meniscus posterior root tear (MMPRT) repair. The modified Mason-Allen (MMA) technique has been proposed as a refixation technique for MMPRT instead of the conventional 2 simple stitches (TSS). This is in view of its superior biomechanical characteristics. PURPOSE: To perform a systematic review and meta-analysis to compare MMA and TSS configuration techniques for MMPRT repair and identify any differences between the 2 techniques in terms of clinical outcomes, medial meniscal extrusion (MME), and postoperative healing. STUDY DESIGN: Meta-analysis; Level of evidence, 4. METHODS: The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase databases were used to perform a systematic review and meta-analysis using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: ("meniscus" OR "meniscal injuries") AND ("Mason-Allen" OR "simple stitch" OR "suture techniques"). Data pertaining to all patient-reported outcome measures, postoperative complications, MME, postoperative healing, cartilage degeneration, and progression of knee osteoarthritis were extracted from each study. The pooled outcome data were analyzed using random- and fixed-effects models. RESULTS: After abstract and full-text screening, 6 clinical studies were included. In total, there were 291 patients; 160 underwent MMA fixation, and 131 underwent the TSS technique. The majority of studies had similar surgical techniques regarding repair technique, suture material, tibial fixation, and number and position of tibial tunnels. There were no differences between the groups in terms of patient-reported outcome measures at 14.2 months. Both techniques were also similar in the degree of postoperative MME and meniscal healing. CONCLUSION: Both suture configurations were equivalent in terms of clinical outcomes, the extent of meniscal extrusion, and postoperative healing. The TSS technique may offer advantages in terms of faster learning curve and shorter operative time. However, randomized controlled trials with large sample sizes, longer follow-up and assessment of chondral degeneration, and presence of knee osteoarthritis are required to assess whether a true difference exists, as the majority of included studies were limited by their retrospective design.

Assessment of meniscal extrusion with ultrasonography: a systematic review and meta-analysis.

BACKGROUND: Magnetic resonance imaging (MRI) is the imaging of choice for meniscal extrusion (ME). However, they may underappreciate the load-dependent changes of the meniscus. There is growing evidence that weight-bearing ultrasound (WB US) is more suitable, particularly in revealing occult extrusion. We therefore perform a systematic review and meta-analysis on the validity and reliability of US in diagnosing extrusion. Furthermore, we explored whether it detects differences in extrusion between loaded and unloaded positions and those with pathological (osteoarthritis and meniscal injury) and healthy knees. METHODS: The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Data pertaining to intra- and interrater reliability of US in measuring meniscal extrusion (ME), its correlation with magnetic resonance imaging (MRI), and head-to-head comparison of potential factors to influence ME were included [loading versus unloading position; osteoarthritis (OA) or pathological menisci (PM) versus healthy knees; mild versus moderate-severe knee OA]. Pooled data were analyzed by random or fixed-effects models. RESULTS: A total of 31 studies were included. Intraclass correlation coefficients (ICC) for intra- and interrater reliability were minimum 0.94 and 0.91, respectively. The correlation between US and MRI was (r = 0.76). US detected ME to be greater in the loaded position in all knees (healthy, p < 0.00001; OA, p < 0.00001; PM, p = 0.02). In all positions, US detected greater extrusion in OA (p < 0.0003) and PM knees (p = 0.006) compared with healthy controls. Furthermore, US revealed greater extrusion in moderate-severe OA knees (p < 0.00001). CONCLUSIONS: This systematic review suggests ultrasonography can play an important role in the measurement of meniscal extrusion, with results comparable to that of MRI. However, to what extent it can differentiate between physiological and pathological extrusion requires further investigation, with an absolute cutoff value yet to be determined. Nevertheless, it is an appropriate investigation to track the progression of disease in those with meniscal pathologies or osteoarthritis. Furthermore, it is a feasible investigation to evaluate the meniscal function following surgery. LEVEL OF EVIDENCE: IV, Systematic review of level III-IV evidence.

Fibular- Versus Tibiofibular-Based Reconstruction of the Posterolateral Corner of the Knee: A Systematic Review and Meta-analysis.

BACKGROUND: Fibular- and tibiofibular-based reconstructions are the gold standard treatment for posterolateral corner (PLC) injuries of the knee. Despite comparable outcomes in biomechanical studies, clinical results comparing these constructs remain elusive with no consensus reached regarding the best treatment option. PURPOSE: To perform a systematic review and meta-analysis to compare fibular- and tibiofibular-based techniques for posterolateral corner reconstruction. We aimed to identify whether any differences existed between the 2 techniques in terms of clinical outcomes and rotational and varus stability. STUDY DESIGN: Meta-analysis; Level of evidence, 4. METHODS: The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review and meta-analysis using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms ("posterolateral corner" OR "fibular collateral ligament" OR "lateral collateral ligament" OR "popliteus tendon" OR "popliteofibular ligament") AND ("reconstruction" OR "LaPrade" OR "Larson" OR "Arciero"). Data pertaining to all patient-reported outcome measures (PROMs), postoperative complications, and valgus and rotational stability were extracted from each study. The pooled outcome data were analyzed by random- and fixed-effects models. RESULTS: After abstract and full-text screening, 6 clinical studies were included. In total, there were 183 patients, of which 90 received fibular-based and 93 tibiofibular-based reconstruction. The majority of studies used similar surgical techniques regarding tunnel orientation, attachment sites, and graft fixation sequence. There were no differences between the groups in terms of PROMs and subjective knee scores at a mean of 20.3 months. The techniques were equally effective in restoring varus and rotational stability. Subgroup analysis revealed that the stability of a posterior cruciate ligament reconstruction postoperatively was not affected by either construct. CONCLUSION: Both constructs had comparable clinical outcomes and were equally effective in restoring varus and rotational stability for PLC knee injuries. The fibular-based technique may offer advantages in view of being less technically demanding and invasive and requiring fewer grafts with a quicker operative time. However, higher quality studies are required to reinforce or refute such conclusions, as the majority of studies in this review were poor to fair quality.

Medial Ulnar Collateral Ligament Repair With Augmentation: A Systematic Review and Meta-analysis of Preclinical Studies.

Background: Reconstruction is the gold standard treatment for medial ulnar collateral ligament (MUCL) injuries. However, recent studies show a successful and renewed interest in direct suture repair, particularly in young athletes. Repair augmentation with a suture tape may provide greater stability, enabling healing of the MUCL while protecting the repair at higher valgus loads. Purpose: To perform a systematic review and meta-analysis on whether MUCL repair with augmentation provides a similar biomechanical profile to the traditional MUCL reconstruction. Study Design: Systematic review. Methods: The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review and meta-analysis using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: ("ulnar collateral ligament" OR "medial ulnar collateral ligament") AND ("internal brace" OR "augmentation" OR "suture tape"). Data pertaining to certain biomechanical properties (gap formation, failure to torque [ultimate load to failure], stiffness, degree of valgus opening, and modes of failure) were extracted. The pooled outcome data were analyzed by random- and fixed-effects models. A total of 203 abstracts were identified through the aforementioned databases. Results: After abstract and full-text screening, 6 biomechanical studies were included. All were on cadaveric elbows, with 53 repairs with augmentation and 53 reconstructions compared. There were no differences between the 2 in regard to ultimate load to failure (standard mean difference [SMD], -0.34 N·m; 95% CI, -1.36 to 0.68; P = .51) and rotational stiffness (SMD, 0.26; 95% CI, -1.14 to 1.66; P = .72). Despite a trend in resistance to gapping with augmented repair, this was not significant (SMD, -0.53; 95% CI, -1.08 to 0.01; P = .06). Augmented repairs were more likely to fail by pullout or at the suture-tendon/anchor-suture interface (odds ratio [OR], 12.19; 95% CI, 4.17 to 35.62; P < .00001), while failure by fracture was more common with reconstruction (OR, 5.75; 95% CI, 2.07 to 15.99; P = .0008). Conclusion: MUCL augmented repair establishes the required time-zero structural properties without the need for a tendon graft. However, future clinical studies are necessary to determine its true effectiveness as well as its success at higher levels of professional sport.

Hexapod Circular Frame Fixation for Tibial Non-union: A Systematic Review of Clinical and Radiological Outcomes.

Introduction: Tibial non-unions present with complex deformities, bone loss, infection, leg length discrepancy (LLD), and other features which influence function. Circular frame-based treatment is popular with the hexapod system used increasingly. This systematic review aims to determine the clinical and radiological outcomes of hexapod fixation when used for tibial non-unions. Materials and methods: The review was performed in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The search strategy was applied to MEDLINE and Embase databases on 15 December 2021. Studies reporting either clinical or radiological outcomes following hexapod fixation on tibial non-unions were included. Primary outcomes were radiological union and patient-reported outcome measures (PROMs). Secondary outcomes included LLD, tibial alignment deformity (TAD), return to pre-injury activity and post-operative complications. Results: After the abstract and full-text screening, 9 studies were included; there were 283 hexapod frame fixations for tibial non-unions. Infection (46.6%) and stiff hypertrophic non-union (39.2%) accounted for most non-unions treated. The average age and mean follow-up were 42.2 years and 33.1 months, respectively. The average time to union was 8.7 months with a union rate of 84.8%. A total of 90.3% of patients had TAD below 5° in all planes, with an LLD ≤1.5 cm of the contralateral leg in 90.5%. Bony and functional results were at least good in over 90% of patients when using the Association for the Study of the Method of Ilizarov (ASAMI) criteria. A total of 84% of patients returned to pre-injury activities. There were complications as follows: a total of 34% developed pin-site infection, almost 9% experienced half-pin breakage and 14% developed an equinus ankle contracture. Conclusion: Hexapod frames for the treatment of tibial non-unions produce favourable functional outcomes. Complication rates are present and need to be discussed when this modality of treatment is proposed. Further comparative studies will allow for this option to be evaluated against that of the traditional Ilizarov frame and other methods of non-union surgery.

Morphological characteristics and management of greater tuberosity fractures associated with anterior glenohumeral joint dislocation: A single centre 10-year retrospective review.

Introduction: Greater tuberosity (GT) fractures associated with anterior gleno-humeral (GH) dislocations are unstable, with inadequate treatment leading to displacement, malunion, stiffness and functional disability. We explored its morphological characteristics to ultimately optimize their management. Methods: We retrospectively reviewed all shoulder radiographs with GT fractures associated with anterior GH dislocations in a university hospital between December 1, 2009 and December 31, 2019. Special considerations were given to fracture morphology, presence and site of comminution, degree of displacement and need for surgical intervention. Results: 133 patients were identified. Most of the fracture-dislocations were multi-fragmentary (86.5%) and located antero- or postero-superiorly (68.7%). Superiorly comminuted GT fractures were twice as likely to displace compared to other sites of comminution (43% vs. 21%, p = 0.03), and require surgery (p = 0.03). Undisplaced comminuted GT fragments, particularly superior patterns, could undergo secondary migration if conservatively treated (p = 0.01). GT fractures fixed with interfragmentary screw suffered more secondary migration but those treated with double-row suture anchors (DRSA) did not on follow-up x-rays at two months. Conclusion: GT fractures with anterior GH dislocations are frequently comminuted. Those with superiorly situated comminution should have a low threshold for surgical fixation, particularly with DRSA which can prevent secondary fragment migration.

Platelet-Rich Plasma in acute Achilles tendon ruptures: A systematic review and meta-analysis.

BACKGROUND: Platelet Rich Plasma (PRP) is known to exert multi-directional biological effects favouring tendon healing. However, conclusions drawn by numerous studies on its clinical efficacy for acute Achilles tendon rupture are limited. We performed a systematic review and meta-analysis to investigate this and to compare to those without PRP treatment. METHODS: The Cochrane Controlled Register of Trials, Pubmed, Medline and Embase were used and assessed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: ('plasma' OR 'platelet-rich' OR 'platelet-rich plasma' or 'PRP') AND ('Achilles tendon rupture/tear' OR 'calcaneal tendon rupture/tear' OR 'tendo calcaneus rupture/tear'). Data pertaining to biomechanical outcomes (heel endurance test, isokinetic strength, calf-circumference and range of motion), patient-reported outcome measures (PROMs) and incidence of re-ruptures were extracted. Meta-analysis was performed for same outcomes measured in at least three studies. Pooled outcome data were analysed by random- and fixed-effects models. RESULTS: After abstract and full-text screening, 6 studies were included. In total there were 510 patients of which 256 had local PRP injection and 254 without. The average age was 41.6 years, mean time from injury to treatment 5.9 days and mean follow-up at 61 weeks. Biomechanically, there was similar heel endurance, isokinetic strength, calf circumference and range of motion between both groups. In general, there were no differences in patient reported outcomes from all scoring systems used in the studies. Both groups returned to their pre-injured level at a similar time and there were no differences on the incidence of re-rupture (OR 1.13, 95% CI, 0.46-2.80, p = 0.79). CONCLUSION: PRP injections for acute Achilles tendon ruptures do not improve medium to long-term biomechanical and clinical outcomes. However, future studies incorporating the ideal application and biological composition of PRP are required to investigate its true clinical efficacy.

Use of Suture Tapes Versus Conventional Sutures for Arthroscopic Rotator Cuff Repairs: A Systematic Review and Meta-analysis.

BACKGROUND: Various suture materials are available for arthroscopic rotator cuff repair. More recently, suture tapes have become popular as they are perceived to be easier to use with less soft tissue irritation. However, little is known about their biomechanical and clinical properties compared with conventional sutures in rotator cuff repairs. PURPOSE: To perform a systematic review and meta-analysis on whether suture tapes are biomechanically superior to conventional sutures in arthroscopic rotator cuff repairs and whether this translates to superior functional outcomes and a lower incidence of retears. STUDY DESIGN: Meta-analysis. METHODS: The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review and meta-analysis using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: (rotator cuff repair OR arthroscopic rotator cuff repair) AND ("tape" OR "wire" OR "cord" OR "suture"). Data pertaining to certain biomechanical properties (contact area, contact pressure, gap formation, load to failure, and stiffness), retears, and patient-reported outcome measures (PROMs) were extracted. The pooled outcome data were analyzed by random- and fixed-effects models. RESULTS: After abstract and full-text screening, 7 biomechanical and 6 clinical studies were included. All biomechanical studies were on animals, with 91 suture tapes and 91 conventional sutures compared. Suture tapes had higher contact pressure (mean difference [MD], 0.04 MPa; 95% CI, 0.01-0.08; P = .02), higher load to failure (MD, 52.62 N; 95% CI, 27.34-77.90; P < .0001), greater stiffness (MD, 4.47 N/mm; 95% CI, 0.57-8.38; P = .02), and smaller gap formation (MD, -0.30 mm; 95% CI, -0.45 to -0.15; P < .0001) compared with conventional sutures. From the clinical analysis of the 681 rotator cuff repairs treated with a suture tape (n = 380) or conventional suture (n = 301), there were no differences in retear rates between the groups (16% vs 20% suture tape and wire, respectively; P = .26) at a mean of 11.2 months. Qualitatively, there were no differences in PROMs between the groups at a mean of 36.8 months. CONCLUSION: Although biomechanically superior, suture tapes showed similar retear rates and postoperative function to conventional sutures. However, higher-quality clinical studies are required to investigate whether there are no true differences.

Intra-articular steroid injections in large joint arthritis: A survey of current practice.

INTRODUCTION: Intra-articular corticosteroid injections are widely used as a management modality for mild large joint osteoarthritis (OA). In contrast, there is little guidance or consensus on the use of steroids in moderate to severe disease. The aim of this study is to explore the current practice of surgeons in relation to the use of therapeutic intra-articular steroid injections in patients awaiting large joint arthroplasty for OA. METHODS: An anonymous questionnaire was distributed to consultants performing large joint arthroplasty in four National Health Service Trusts. Participants were questioned on their use of intra-articular therapeutic steroid injections in patients listed for elbow, shoulder, hip or knee arthroplasty. Data was collected over 6 months and analysed using Microsoft Excel. RESULTS: A total of 42 surgeons were included in the study with the majority performing lower limb arthroplasty (73%). About 21 (50%) surgeons indicated they would perform injections in the patient group of interest. Two would perform an unlimited number of injections, whilst the remainder would perform between one and three injections. Respondents most commonly indicated they would tell patients that an injection would provide between 6 and 12 weeks of benefit (14 of 39 surgeons, 36%). Most injecting surgeons (88%) leave 4 months between an injection and subsequent arthroplasty due to increased risk of infection if surgery is performed sooner. CONCLUSION: This study demonstrates variation in practice in the use of intra-articular steroids in the analysed patient group, and the way surgeons council their patients. National or specialist society guidelines may help to reduce this variation in practice.

Total hip arthroplasty in Parkinson's disease - A systematic review of the current evidence.

This systematic review assessed the efficacy, survivorship, and complications of Total Hip Replacement (THR) in Parkinson's Disease (PD). Databases were searched according to the Preferred Reporting Items for Systematic Reviews. PD patients had higher wound infections, dislocations, peri-prosthetic fractures, and revision surgery compared to their non-PD counterparts. They also had inferior functional outcomes, and longer and expensive hospital admissions. Dual-mobility (DM) implants had the lowest survival rate. THR in PD patients is associated with significant surgical complications and peri-operative challenges. Despite the use of DM implants to minimize instability, there is insufficient evidence on its effectiveness and long-term survivorship.

Dorsal bridge plating versus. Transarticular screw fixation for lisfranc injuries: A systematic review and meta-analysis.

Lisfranc injuries are relatively uncommon but carry devastating consequences if left untreated. Although many surgical techniques have been proposed for best operative management, there is an ongoing debate over which procedure is superior. We performed a systematic review and meta-analysis comparing the outcomes of transarticular screw fixation and dorsal bridge plating in management of Lisfranc injuries. Ovid MEDLINE, Ovid Embase and Cochrane Central Register of Controlled Trials (CENTRAL) were searched to identify randomised controlled trials (RCTs) and cohort studies comparing the outcomes between screw and dorsal plate fixation. The pooled outcome data were calculated by random and fixed effect models. One prospective cohort and three retrospective studies were identified with a total of 210 patients with mean follow up of 40.6 months. All papers were analysed for quality using the modified Newcastle Ottawa score. The results show that dorsal bridge plating is associated with better American Orthopaedic Foot and Ankle Society score (AOFAS) compared with transarticular screw fixation (OR - 0.71, 95% CI -1.31 to -0.10, p = 0.02). Dorsal plating may also be associated with fewer cases of arthritis, although this was not significant (OR 2.46, 95% CI 0.89 to 6.80, p = 0.08). We found no significant differences between the groups in terms of Foot Function Index (FFI), post traumatic arthritis and failure of hardware material. Although our results suggest dorsal bridge plating may provide superior functional outcomes, there is a scarcity of literature with little robustness to make definitive conclusions. High quality randomised trials are required.

Balanitis xerotica obliterans: has its diagnostic accuracy improved with time?

OBJECTIVES: We observed whether general practitioners are referring more appropriately for balanitis xerotica obliterans in regards to circumcision, especially at a time of clinical concern, and whether their discriminative abilities were affected by age. We also aimed to explore if balanitis xerotica obliterans was over-diagnosed by surgeons potentially leading to unnecessary circumcisions of healthy foreskins. DESIGN: Cross-sectional descriptive study. SETTING: Leicester Royal Infirmary. PARTICIPANTS: All children less than 16 years of age were included and were subsequently split into two categories: those less than or equal to five years and those above five years. Circumcision was justified if surgeon found pathology under foreskin commissioning guidelines set by the Royal College of Surgeons of England. After clinical diagnosis of balanitis xerotica obliterans, the pathological database was searched for histological confirmation. MAIN OUTCOME MEASURES: Has diagnostic accuracy improved amongst general practitioners for balanitis xerotica obliterans and is there a high clinical to histological confirmation. RESULTS: Of the total patients, 14.5% were diagnosed clinically with balanitis xerotica obliterans. Only 66.7% of cases were histologically confirmed with chronic inflammation found in the rest; 5.5% of all boys referred had balanitis xerotica obliterans on histology; and 8.2% of children <5 had clinical balanitis xerotica obliterans with 1.7% confirmed histologically. This was in contrast with 18.1% and 9.2% found in the older cohort. CONCLUSION: There remains a high diagnostic inaccuracy amongst general practitioners when referring for balanitis xerotica obliterans. This is greatest in those under five years. Although balanitis xerotica obliterans was over-diagnosed, no healthy foreskin underwent unnecessary circumcision.
