Introduction

Multiligament knee injuries (MLKI) are rare and complex, significantly impacting long-term outcomes, with risks of osteoarthritis, joint stiffness, and reduced activity levels.

Objective

To explore the evolution of MLKI treatment protocols, comparing historical and modern approaches, and to present a patient-tailored, preservation-first algorithm.

Methods

This article reviews the literature on MLKI management, focusing on surgical timing, techniques, and rehabilitation protocols. The proposed algorithm categorizes MLKIs based on tear location and tissue quality, incorporating options, such as primary ligament repair, augmentation, and reconstruction.

Results

The modern preservation-first algorithm provides a tailored approach to MLKI treatment, addressing the complexity and heterogeneity of these injuries, and aims to mitigate risks like postoperative arthrofibrosis.

Conclusion

MLKI management remains complex and controversial. The presented algorithm offers a structured, individualized treatment strategy that integrates modern surgical and rehabilitation advancements.

Lateral extra-articular tenodesis (LET) has shown an upswing in popularity since the role of antero-lateral rotatory instability (ALRI) in ACL tears has become better understood. Its primary aim is to restore antero-lateral rotatory stability and hence reduce stresses placed on the ACL graft in high-risk individuals which should reduce graft failure rates. Many techniques have been described for LET using a variety of fixation methods (screws, anchors, etc.). Most of these techniques rely on a large incision laterally. We describe a novel technique (‘mini-LET’) which uses a 3–4 cm incision, to improve cosmesis.

Background

Continuous compression implants (CCIs) can provide continuous compression across a fracture site. They are mainly used in foot/ankle surgery, with very limited descriptions in the literature of their potential for trauma. The aim of this study was to describe the use and associated outcomes of CCIs in modern day trauma practice.

Methods

This was a single-centred case series with a retrospective analysis of a prospectively maintained database of any patients who were treated with a CCI across 4 years. The primary outcome was to determine the mode of the CCIs and secondary outcomes were unplanned returns to theatre.

Results

60 patients were eligible with a mean age of 44.2 and 122 CCIs were used. 51 patients were treated for acute fractures, 9 were treated for non-unions, and 27 patients had open injuries. 42 of the 122 CCIs were used as definitive fixation (midfoot dislocations, an iliac wing fixation and isolated medial malleolus fixation), and the rest as adjuncts for fixation; of this remainder, 39 were used in reduction mode, 38 for fixation of key fragments, and 3 for compression. Ten patients returned to theatre, two for metalwork failure, two for infection and 6 for non-unions—three were acute fractures and three originally non-unions.

Conclusion

This paper demonstrates a novel technique for the use of CCIs in UK trauma practice as either definitive fixations or in three different modes as adjuncts to fixation. They do not replace tradition implants but do have equivalent rates of complications. They may be a useful tool in the arsenal for trauma surgeons.

Introduction

ACL tears are the most common injuries in kabaddi, an inherently violent high pivoting and high-velocity direct contact sport. Combined ACL and MCL injuries and combined ACL and ALL injuries have been better understood but there is a lacuna of literature on these combined injuries in kabaddi players and no literature on combined AMRI and ALRI injuries. The present prospective cohort study aims to assess knee outcomes and return to sport for these injuries in elite kabaddi players.

Methods

A prospective cohort of 26 elite kabaddi players with clinical and MRI findings of ACL and MCL high-grade partial or complete tears were recruited. After ACL reconstruction and MCL repair, the resultant pivot shift was assessed against the now intact medial pillar and those with high-grade or explosive pivot were addressed using a modified deep Lemaire lateral extra-articular tenodesis. Pain scores (VAS) and knee outcomes (IKDC and Lysholm scores) were assessed pre-operatively and at regular intervals until 1-year follow-up. Return to sport and complications were also assessed.

Results

There was significant improvement in pain and knee scores throughout the study period, with most patients achieving full scores by six months duration. Return to sport was 96% and return to sport at pre-injury level was 77%. Complication rate of the combined triple procedure was low (< 5%), with most complications being minor.

Conclusion

The triple procedure of ACL reconstruction, MCL repair and Lateral extraarticular tenodesis successfully addressed the combined AMRI and ALRI in elite kabaddi players with a high rate of return to sport, excellent knee outcomes and low complication rate.

Introduction

Graft diameters are essential in any ACL surgery, with diameters less than 8mm associated with higher revision rates. Peroneus longus (PL) grafts have garnered much attention recently due to ease of harvest and more reliable graft diameters. The present study aimed to study various anthropometric parameters associated with PL-graft diameters.

Methods

We performed a prospective cohort study of 50 patients undergoing PL harvest for ACL surgery at a tertiary referral hospital. Age, gender, height, weight, length of the lower leg (lateral tibial plateau to the tip of the fibula), circumference at the head of the fibula and girth at the lateral malleolus were measured pre-operatively. The length of the graft doubled and tripled graft diameters were assessed intra-operatively. Pearson correlation coefficient was used to study the association between the pre-operative anthropometric variables and the intra-operative graft diameters and length of graft harvested.

Results

The mean doubled and tripled PL-graft diameter in our study population was 7.7 ± 0.9 mm and 8.7 ± 0.8 mm, respectively. The mean length of the graft was 25.9 ± 3.5 cm. We found no significant correlation between graft diameters and age, gender or height of the patient. We found that the patient's weight significantly correlated (p < 0.001) with graft diameter. We also found that the length of the lower leg (p < 0.0001), circumference at the head of the fibula (p = 0.001) and girth at the lateral malleolus (p = 0.029) showed significant correlation with tripled PL-graft diameter.

Conclusion

We found that weight, length of the lower leg and girth at the head of the fibula showed a strong correlation with tripled PL-graft diameter.

Introduction

Hydatid disease is uncommon in Humans. It rarely affects the bones and joints (0.5–4%). Frequent sites of bony involvement are vertebrae, pelvic bones, upper end of long bones e.g. humerus, femur and tibia.

Material and methods

We report a case of 41-year old female with primary Hydatid cyst of the entire right femur. Patient complaint of severe pain and was non ambulatory since the last 2 months.

Results

Here, single staged Total Right Femur Replacement was done under General Anaesthesia. Patient was discharged after 6 days of hospital stay in a stable condition where physical rehabilitation was initiated after day one of the surgery, progressing to aided walking, standing and active lower limb exercises.

Conclusion

Involvement of the entire femur was a challenging case. There is no consensus/gold standard treatment of severe cases. Given the involvement of the entire Right Femur along with spillage in the neighbouring muscles, patient underwent Total Femur Replacement with Hip and Knee Replacement.

Operating room fires are considered ‘never events’; they are uncommon but can prove to be potentially damaging to the humans involved and the expensive operating room instrumentation. Research indicates that significant knowledge gaps exist in orthopaedic community relating to fire prevention, fire safety and fire management. A 24-year-old male patient with clavicle fracture was planned for surgical fixation. A nerve block procedure was performed. Skin preparation was done with 10% betadine scrub and surgical spirit. The surgical team performed skin incision, and superficial dissection was carried out using electrocautery. A fire broke out, and on noticing the fumes, saline was poured, drapes were removed and the authors observed charring of deeper linen and skin damage. A superficial thermal burn, greenish blue in colour (7 x 1.5 cms) located 1–1.5 cms above the surgical incision was evident (see Fig. 4). The event was later explained to the patient. The surgical scar was healthy, and burn margins became defined and darkish green blue. Dressing was done with megaheal ointment. The burn healed in 4 weeks. As these events are rare, a specific action protocol has not been orchestrated. With newer reports coming in, orthopaedic associations should work out a sustainable plan of action to minimize the occurrence of these events and the damage incurred. Training of orthopaedic and anaesthesia team and operating room personnel remains the most important step in countering a fire event, as more the helping hands, the better is the outcome. Maintaining a high vigil ensures timely action response to maintain patient safety and counter adverse events effectively.

Introduction

Knee osteoarthritis (OA) is a prevalent condition that significantly impacts the quality of life, often leading to the need for knee replacement surgery. Accurate and timely identification of knee degeneration is crucial for effective treatment and management. Traditional methods of diagnosing OA rely heavily on radiological assessments, which can be time-consuming and subjective. This study aims to address these challenges by developing a deep learning-based method to predict the likelihood of knee replacement and the Kellgren–Lawrence (KL) grade of knee OA from X-ray images.

Methodology

We employed the Osteoarthritis Initiative (OAI) dataset and utilized a transfer learning approach with the Inception V3 architecture to enhance the accuracy of OA detection. Our approach involved training 14 different models—Xception, VGG16, VGG19, ResNet50, ResNet101, ResNet152, ResNet50V2, ResNet101V2, ResNet152V2, Inception V3, Inception, ResNetV2, DenseNet121, DenseNet169, DenseNet201—and comparing their performance.

Results

The study incorporated pixel ratio computation and picture pre-processing, alongside a decision tree model for prediction. Our experiments revealed that the Inception V3 model achieved the highest training accuracy of 91% and testing accuracy of 67%, with notable performance in both training and validation phases. This model effectively identified the presence and severity of OA, correlating with the Kellgren–Lawrence scale and facilitating the assessment of knee replacement needs.

Conclusion

By integrating advanced deep learning techniques with radiological diagnostics, our methodology supports radiologists in making more accurate and prompt decisions regarding knee degeneration. The Inception V3 model stands out as the optimal choice for knee X-ray analysis, contributing to more efficient and timely healthcare delivery for patients with knee osteoarthritis.

Background

Multi-ligament Knee Injuries (MLKI) are often caused by a high-energy impact resulting in dislocation of the knee joint. Given the higher degree of instability associated with these MLKIs, surgical fixation with adjunctive internal bracing and the use of suture augmentation have been proposed with the intention of better restoring knee stability and improving the long-term outcomes of surgery. This systematic review seeks to appraise the current literature in relation to the role of internal bracing in the management of MLKI.

Methods

All randomised control trials, observational studies, cohort studies, and cross-sectional studies containing patients with multi-ligamentous knee injuries managed with the use of internal bracing or suture tape augmentation were included in this review. The primary outcomes of interest were re-operation and failure rates, with secondary outcomes focussed on patient-reported outcome measures (PROMs) and examination findings of knee stability.

Results

282 studies were identified for screening, 13 of which were suitable for inclusion and five of these had injuries with Schenck grade III or above. Of the studies identified, failure rates ranged from 0 to 13.6%. Lysholm score was the most commonly utilised PROM tool with scores ranging from 61.8 to 95. Stiffness requiring MUA ± adhesiolysis was a common complication identified across studies.

Conclusions

The use of internal bracing in Multi-ligament Knee Injuries appears to be as effective as not using an internal bracing technique. The post-operative PROMs and relatively low failure rates reflect promising outcomes for the ongoing use of internal bracing in MLKI. However, further prospective studies directly comparing braced versus non-braced ligamentous repairs are required in order to definitively determine if the use of the internal brace does allow for increased joint stability and early rehabilitation.

Background

Average bone healing times of common fractures in adults ranges from 3 to 12 weeks and is location dependent. Platelet Rich Plasma (PRP) stimulates natural healing process through growth factors contained in platelets and has been employed for the same in delayed unions.

Methods

All patients > 18 years and documented delayed union were included in the study. Patients were followed up monthly after each Leucocyte-rich PRP (LR-PRP) injection and a decision for repeat PRP injection was taken on basis of visible impression in radiograph after previous injection.

Results

Total 36 patients were studied in which 5 patients were lost to follow-up. Union was achieved in 28/31 (90.3%). 20 (71.4%) patients required only single PRP injections. 4 (14.3%) patients required 2 PRP injections, 3 (10.7%) patients required 3 PRP injections and 1 (3.6%) patient required 4 PRP injection. There was no significant correlation of number of PRPs to time from 1st PRP-union or time from last PPR- union.

Conclusion

Single/multiple dose percutaneously administered LR-PRP can be used as a fruitful alternative to catalyze union in patients having delayed union irrespective of site of injury.
