CASE
A 47-year-old male with swelling over the patella and associated pain, subsiding with medicines but recurring after a few days. Diagnosed as prepatellar bursitis by the family physician, it eventually turns out to be osteomyelitis of the patella. Treated with curettage, biopsy, and placement of bio-composite mixed with antibiotics. Intra-operative findings and histopathology confirmed tuberculosis of the patella. On follow-up after 6 years and the completion of anti-tuberculosis treatment, the patient showed full functional and radiological recovery without recurrence.
CONCLUSION
Early treatment with antibiotics and surgery gives excellent results. Identifying it as a tuberculous osteomyelitis is challenging when the condition is closely resembles pre-patellar bursitis.

The thickness change ratio and preservation ratio of the infrapatellar fat pad are related to anterior knee pain in patients following medial patellofemoral ligament reconstruction.
BACKGROUND
The infrapatellar fat pad (IPFP) lies extrasynovial and intracapsular, preserving the joint cavity and serving as a biochemical regulator of inflammatory reactions. However, there is a lack of research on the relationship between anterior knee pain (AKP) and the IPFP after medial patellofemoral ligament reconstruction (MPFLR). Pinpointing the source of pain enables clinicians to promptly manage and intervene, facilitating personalized rehabilitation and improving patient prognosis.
METHODS
A total of 181 patients were included in the study. These patients were divided into the AKP group (n = 37) and the control group (n = 144). Clinical outcomes included three pain-related scores, Tegner activity score, patient satisfaction, etc. Imaging outcomes included the IPFP thickness, IPFP fibrosis, and the IPFP thickness change and preservation ratio. Multivariate analysis was used to determine the independent factors associated with AKP. Finally, the correlation between independent factors and three pain-related scores was analyzed to verify the results.
RESULTS
The control group had better postoperative pain-related scores and Tegner activity score than the AKP group (P < 0.01). The AKP group had lower IPFP thickness change ratio and preservation ratio (P < 0.001), and smaller IPFP thickness (P < 0.05). The multivariate analysis revealed that the IPFP thickness change ratio [OR = 0.895, P < 0.001] and the IPFP preservation ratio [OR = 0.389, P < 0.001] were independent factors related to AKP, with a significant correlation between these factors and pain-related scores [|r| > 0.50, P < 0.01].
CONCLUSIONS
This study showed the lower IPFP change ratio and preservation ratio may be independent factors associated with AKP after MPFLR. Early detection and targeted intervention of the underlying pain sources can pave the way for tailored rehabilitation programs and improved surgical outcomes. LEVEL OF EVIDENCE LEVEL III.

Comparative Study
[Comparison of effectiveness of tibial intramedullary nailing fixation via suprapatellar approach and medial parapatellar approach in treatment of multiple tibial fractures].
OBJECTIVE
To compare the effectiveness of intramedullary nailing fixation via suprapatellar approach and medial parapatellar approach in semi-extended position in the treatment of multiple tibial fractures.
METHODS
The clinical data of 43 patients with multiple tibial fractures treated with intramedullary nailing fixation between July 2018 and December 2022 were retrospectively analyzed, including 23 patients treated with suprapatellar approach in semi-extended position (group A) and 20 patients with medial parapatellar approach in semi-extended position (group B). There was no significant difference in gender, age, cause of injury, time from injury to operation, AO/Orthopaedic Trauma Association (AO/OTA) classification, preoperative visual analogue scale (VAS) score, and range of motion (ROM) of the knee joint between the two groups ( >0.05). The operation time, intraoperative blood loss, incision length, intraoperative fluoroscopy frequency, and fracture healing time were recorded and compared. The VAS score and ROM of the knee joint were analyzed at 4, 8, and 12 weeks after operation, and the incidence of postoperative complications was observed; knee function was evaluated by Lysholm score at last follow-up.
RESULTS
The operations were successfully completed in both groups, and there was no complication such as nerve and blood vessel injury during operation, and all incisions healed by first intention. There was no significant difference in operation time, intraoperative blood loss, and intraoperative fluoroscopy frequency between the two groups ( >0.05), but the incision length in group B was significantly longer than that in group A ( <0.05). Patients in both groups were followed up 12-30 months, with an average of 21.1 months. The VAS score decreased and ROM increased gradually in both groups with time after operation, showing significant differences between different time points ( <0.05). The VAS score of group B was significantly lower than that of group A at 4 and 8 weeks after operation ( <0.05); there was no significant difference in VAS score and ROM between the two groups at other time points ( >0.05). There was no significant difference in fracture healing time between the two groups ( >0.05). During the follow-up, there was no complication such as internal fixator loosening, breakage, and loss of fracture reduction. At last follow-up, the Lysholm score in group B was significantly better than that in group A ( <0.05).
CONCLUSION
Both the suprapatellar approach and the medial parapatellar approach in semi-extended position can achieve satisfactory results in the treatment of multiple tibial fractures. The medial parapatellar approach has lower symptoms of early knee pain and better long-term function.

Articular cartilage defects are common injuries of the knee. The defects often progress in size and produce significant clinical symptoms due to the lack of intrinsic repair or regenerative capacity of articular cartilage. With the failure of nonoperative treatment options, surgical treatment is indicated and includes palliative, reparative, and regenerative options. For large defects of the femoral condyles, trochlea, or patella, autologous chondrocyte implantation can provide successful and long-lasting results. Presented is the case of a 37-year-old male with an 18-year follow-up to autologous chondrocyte implantation for extensive left knee articular cartilage defects of the medial and lateral femoral condyles. Recovery from articular cartilage defects is shown through both clinical improvement of the patient and arthroscopic photographs of robust autologous articular cartilage on the medial femoral condyle. This case supports the long-term benefits of autologous chondrocyte implantation as a surgical intervention for large, full-thickness articular cartilage defects of the knee.

INTRODUCTION
Patella fractures account for 1 % of all skeletal fractures, and can interrupt the knee's extensor apparatus. They can also be serious if associated with a cutaneous opening. We report the case of a fracture of the tip of the patella with a large loss of cutaneous substance.
CASE REPORT
A 22-year-old man was admitted for the management of a left knee trauma following a motorcycle accident. Clinical examination revealed a large loss of skin substance on the anteromedial aspect of the knee, with exposed bone, pain and lack of extension of the left knee. Standard X-ray of the left knee showed an avulsion fracture of the tip of the patella. The patient underwent patellar tendon reconstruction using transosseous stitches, reinforced by a quadricipital tendon reversal plasty, and protected by steel-wire patellotibial cerclage. A medial gastrocnemius flap was used to cover the loss of skin substance. After a functional rehabilitation protocol, the functional results were satisfactory, with a full return to activity after six months.
CONCLUSION
The stability of osteosynthesis using quadricipital tendon reversal plasty and patellotibial cerclage allows mobilization and immediate weight-bearing. This may lead to better clinical results.

PURPOSE
Patellar cartilage lesions are a frequent and challenging finding in orthopaedic clinical practice. This study aimed to evaluate a chitosan-based scaffold's mid-term clinical and imaging results patients with patellar cartilage lesions.
METHODS
Thirteen patients (nine men, four women, 31.3 ± 12.7 years old) were clinically evaluated prospectively at baseline, 12, 24 and at a final minimum follow-up of 60 months (80.2 ± 14.7) with International Knee Documentation Committee (IKDC) subjective, Knee Injury and Osteoarthritis Outcome Score and Tegner scores. A magnetic resonance analysis was performed at the last follow-up using the Magnetic resonance Observation of CArtilage Repair Tissue (MOCART) 2.0 score.
RESULTS
An overall significant clinical improvement in the scores was observed from baseline to all follow-ups, with stable clinical results from 24 months to the mid-term evaluation. The IKDC subjective score passed from 46.3 ± 20.0 at baseline to 70.1 ± 21.5 at the last follow-up ( = 0.029). Symptoms' duration before surgery negatively correlated with the clinical improvement from baseline to the final follow-up ( = 0.013) and sex influenced the improvement of activity level from the preoperative evaluation to the final follow-up, with better results in men ( = 0.049). In line with the clinical findings, positive results were documented in terms of cartilage repair quality with a mean MOCART 2.0 score of 72.4 ± 12.5.
CONCLUSIONS
Overall, the use of this chitosan-based scaffold provided satisfactory results with a stable clinical improvement up to mid-term follow-up, which should be confirmed by further high-level studies to be considered a suitable surgical option to treat patients affected by patellar cartilage lesions.

INTRODUCTION
Central hip dislocations are rare orthopedic injuries, and their concomitant occurrence with ipsilateral knee dislocations is an even rarer phenomenon. We present a unique case of central hip dislocation along with ipsilateral knee dislocation and additional fractures involving the lateral condyle of the left tibia and patella. This complex injury pattern resulted from a severe road traffic accident, necessitating operative management to address the multiple musculoskeletal injuries. Ultimately, femoral head avascular necrosis (AVN) developed, leading to the need for total hip replacement (THR).
CASE REPORT
A 28-year-old male was involved in a high-impact road traffic accident, leading to central hip dislocation, ipsilateral knee dislocation, and fractures of the lateral condyle of the left tibia and patella. The patient was promptly assessed, and operative intervention was initiated. Closed reduction and internal fixation with K-wires were performed for the fractures of the lateral condyle of the left tibia and patella. For the central hip dislocation, open reduction was achieved using a 9-hole RECON plate. Following the procedures, a long leg slab was applied for 6 weeks to facilitate optimal healing.Postoperatively, at the 6-week mark, K-wires were removed, and the patient commenced physiotherapy with partial weight-bearing permitted. However, during the rehabilitation phase, the patient reported instability in his left knee. Magnetic resonance imaging revealed an avulsion fracture of the posterior cruciate ligament (PCL) from its tibial attachment site and a complete anterior cruciate ligament (ACL) tear. It was observed that the femoral head had developed AVN. This complication necessitated further intervention, leading to the performance of a THR.
DISCUSSION
This case underscores the challenges and complexities associated with managing central hip dislocation and ipsilateral knee dislocation with multiple fractures. The post-operative instability of the knee, diagnosed as an avulsion fracture of the PCL and complete ACL tear, necessitated additional intervention. The patient subsequently underwent PCL reconstruction using a semitendinosus graft, highlighting the importance of a comprehensive approach to address the diverse musculoskeletal injuries resulting from high-impact trauma.
CONCLUSION
The successful management of central hip dislocation and ipsilateral knee dislocation with associated fractures requires a multidisciplinary approach, incorporating timely surgical intervention, rigorous rehabilitation, and vigilant post-operative monitoring to address potential complications. This case emphasizes the need for ongoing clinical assessment and imaging studies to identify and manage secondary injuries that may manifest during the recovery phase. In addition, it highlights the development of femoral head AVN, ultimately leading to the necessity for THR.

Periosteal sleeve fractures, or avulsions of cartilage and/or periosteum with or without an osseous fragment in skeletally immature individuals, are notoriously easy to miss and a high index of suspicion is necessary for accurate diagnosis and treatment. While periosteal sleeve avulsion fractures are classically reported in the patella, they have also been reported in the shoulder, clavicle, and elsewhere in the knee. However, no published reports exist for a periosteal sleeve avulsion fracture in the hand. This case details the first reported instance of such an injury involving a thumb metacarpal in a 3-year-old boy, treated with open reduction and percutaneous pinning of the thumb metacarpal.

OBJECTIVES
Robotic-tools have been developed to improve planning, accuracy and outcomes in total knee arthroplasty (TKA). The purpose of this study was to describe and illustrate a novel technique for assessing the patellofemoral (PFJ) in TKA using an imageless robotic platform.
METHODS
A consecutive series of 30 R-TKA were undertaken by a single-surgeon utilising the described technique. A technique to dynamically assess the PFJ intra-operatively, pre and post implantation was developed. A full set of data from 9 cases was then collected and reviewed for analysis. A series of dynamic PFJ tracks collected intra-operatively pre and post implantation are presented. Furthermore, a full assessment of PFJ over and under-stuffing through a 90° arc of flexion is illustrated. Finally, a pre and post centre of rotation for the PFJ was defined and measured.
RESULTS
The described technique was defined over a series of 30 R-TKA using the described robotic platform. Nine cases were analysed to determine what data could be measured using the robotic platform. Intra-operative real-time data allowed a visual assessment of PFJ tracking through a range of motion of 0° to 90° flexion pre and post-implantation. PFJ over and under-stuffing was also assessed intra-operatively through a range of motion of 0° to 90° flexion. Post operative analysis allowed a more detailed study to be performed, including defining a pre and post implantation centre of rotation (COR) for the patella. Defining the COR allowed the definition of a patella plane. Furthermore, patella mediolateral shift in full extension, and end flexion could be measured.
CONCLUSION
Intra-operative assessment of the PFJ in TKA is challenging. Robotic tools have been developed to improve measurement, accuracy of delivery and outcomes in TKA. These tools can be adapted in novel ways to assess the PFJ, which may lead to further refinements in TKA techniques.

Female gender is one of the commonly mentioned risk factors for anterior knee pain (AKP), among a spectrum of other factors including anatomical, biomechanical, hormonal, behavioral, and psychological elements contributing to its development. Despite the focus on individual risk factors, there's a notable gap in comprehending how gender influences and interacts with other risk factors. The objective of this review was to identify and emphasize the connections between these interactions, gender-related risk factors for AKP, and the potential mechanisms that explain their associations with other risk factors, aiming to aid in the creation of precise prevention and treatment approaches. Gender influences the majority of risk factors for AKP, including anatomical, biomechanical, hormonal, behavioral, and psychological factors. Women have on average smaller patellae, higher patellofemoral cartilage stress and for AKP, disadvantageous trochlear morphology, ligament and muscle composition and unfavorable neuromuscular control pattern. In contrast, men show on average an increased ability to strengthen their hip external rotators, which are both protective against AKP. Particularly in kinetic and kinematic analysis, men have been shown to have a distinctly different risk factor profile than women. Sex hormones may also play a role in the risk of AKP, with estrogen potentially influencing ligamentous laxity, increasing midfoot loading and affecting neuromuscular control of the lower extremities and testosterone positively affecting muscle mass and strength. The higher incidence of AKP in women is likely due to a combination of slightly increased risk factors. Although all risk factors can be present in both men and women and the holistic evaluation of each individual's risk factor composition is imperative regardless of gender, knowing distinctive risk factors may help with focused evaluation, treatment, and implementing preventive measures of AKP.
