RESUMEN
PURPOSE: The cumulative effect of hyper-coagulative COVID-19 disease and using steroids leads to increased avascular necrosis (AVN) hip incidence. This study aims to correlate the various factors of COVID-19 infection with the occurrence of AVN hip. METHODS: It is a retrospective cross-sectional study of non-traumatic AVN hip patients with a history of COVID-19 infection. A total number of 50 patients satisfied the inclusion criteria. The following details were obtained: (a) patient's demographics, (b) COVID-19: interval of infection and groin pain, duration of symptoms, severity, steroid intake, (c) AVN hip: involved side, Ficat-Arlet staging. RESULTS: The mean age was 36.3 years (range: 20-60), and body mass index (BMI) was 25.13 kg/m2 (range: 18.50-31.50). There were 45 males and five females. Sixty percent (30) of patients managed at home, 24% (12) required admission into the ward, 2% (1) were in ICU only, and 14% (7) admitted to both ICU and ward. The mean interval of COVID-19 infection and onset of hip pain was 359.02 days (range: 10-822 days). Thirty-eight percent (19) patients required steroids (injection and oral), 46% (23) took steroids (oral only), whereas 16% (8) recovered without steroids. The stage of AVN correlated with the severity of COVID-19 infection (p-value -0.038) and significant improvement in VAS and HHS after treatment in each stage. The mean follow-up was 9.79 months (6-19 months). CONCLUSION: A low-dose steroid intake with moderate to severe COVID-19 infection produces an additive effect on the development of AVN hip. Most affected individuals were adult males, and stage II AVN was the most common, managed with bisphosphonates and core decompression for short intervals.

INTRODUCTION: Arthroscopic debridement of the knee is usually considered a safe procedure. There are no case reports of medial patellofemoral ligament (MPFL) injury leading to habitual dislocation of the patella following this procedure in the literature. CASE PRESENTATION: A 35-year-old male presented with complaints of habitual dislocation of the left patella, which he noticed after multiple arthroscopic surgeries of the left knee performed elsewhere. He had a history of septic arthritis of the knee following anterior cruciate ligament reconstruction, for which he underwent arthroscopic debridement of the knee twice. After a detailed evaluation, we noticed MPFL medial patellofemoral ligament injury. CONCLUSION: The MPFL medial patellofemoral ligament injury occurred as a result of extensive resection of the medial joint capsule while operating for septic arthritis. This rare grave surgical complication emphasizes the care one should take during arthroscopic debridement of the knee.
RESUMEN
PURPOSE: We have consistently observed a connective tissue lining over the intercondylar notch's roof (CTLINR) during arthroscopic surgeries of the knee joint. As there is a strong association of the intercondylar fossa with the anterior cruciate ligament (ACL), we believe that this tissue must be having some role in the functioning of the ACL. The purpose of this pilot study was to investigate the anatomic characteristics of the CTLINR. METHODS: In this observational anatomical study, we have investigated the gross anatomical and histological features of the CTLINR in four knees of two fresh frozen non-embalmed cadavers. We have also studied its ultrastructural characteristics by obtaining an arthroscopic biopsy of the tissue from a patient undergoing ACL reconstruction. RESULTS: At gross examination, the CTLINR had a typical glistening white surface with transversely oriented fibres. It entirely covered the roof of the intercondylar notch and was soft to touch. Histological examination with haematoxylin-eosin stain revealed fibro-collagenous tissue with intervening blood vessels. Transmission electron microscopy manifested loosely arranged collagen fibres of variable diameter. CONCLUSION: The histological and electron microscopic characteristics of the tissue differentiate it from the ACL and its femoral enthesis, suggesting that it was a distinct anatomical structure. As it entirely covered the roof of the intercondylar fossa and had a smooth surface and soft consistency, it may protect the reconstructed ACL from graft abrasion. Furthermore, as it had a characteristic arthroscopic appearance, future research can investigate its role in femoral tunnel positioning.

There is a paucity of literature regarding a neglected shoulder dislocation, as it is unusual to miss it clinically due to the apparent deformity. Nevertheless, in some cases, particularly those who received the primary treatment from a local bonesetter, present with neglected dislocation. No high-level studies comparing different treatment modalities in such a situation are available. Therefore, most of the treatment recommendations are based on level four studies and the literature for recurrent dislocation of the shoulder. We herewith describe two cases of neglected anterior dislocation of the shoulder, which we have managed by open reduction and Latarjet procedure in one and Bankart surgery in the other patient. Both of our patients after one-year follow-up had a painless joint with improved yet limited range of motion. This case discussion helps in learning the approach towards the treatment of these patients. It also suggests a sub-optimal functional outcome in them.
RESUMEN
Femoral tunnel preparation during the anterior cruciate ligament reconstruction is a technically demanding step. The anteromedial (AM) portal technique necessitates knee hyperflexion during the femoral tunnel reaming. In a hyperflexed knee, the arthroscopic visualization of the laser markings on the femoral tunnel reamer becomes obscured. Thus, the calculation of the depth of the femoral tunnel becomes difficult. Our technique helps in femoral tunneling reliably without the need for arthroscopic visualization using the AM portal as a reference point to calculate the depth while drilling. This technique can be performed without the need for a second assistant to hold the arthroscope. Furthermore, this technique does not require any specific instruments, and there is no obligation for an additional incision.
RESUMEN
We herewith report a case of a 22-year-old man who suffered from a transverse laceration of the quadriceps muscle. The patient presented to us after 3 months of the injury with an inability to extend the knee. We undertook a surgical repair of the muscle tear using the modified Mason-Allen technique and a polypropylene mesh augmentation. To the best of our knowledge, the use of polypropylene mesh for repair augmentation of mid-substance tear of quadriceps muscle has never been described in the literature. The patient had achieved a full active knee extension at 9 months following the surgery. At 3 years of follow-up, the patient has maintained the movements and strength of the knee. He has no functional limitations and is satisfied with the outcome. Thus, the middle term results are good and the treatment is promising.

Introduction: Madura foot is a rare infective granulomatous foot disease. The burden of this disease has significantly declined in recent years due to better generalized living conditions. Hence, the diagnosis can be quite often missed by the new generation orthopedic surgeon for other more similar conditions. Early diagnosis and prompt treatment is crucial for better outcome and limb survival. We here present the clinical picture of three such Madura foot cases. Case Series: In this study, three Indian males aged between 40 and 60 years of rural background presented to our department with chronic multiple discharging sinuses of the foot. They were initially treated for several months in their local health centers without any improvement. Finally, they came to our institution where they were thoroughly inspected and underwent various investigations such as magnetic resonance imaging (MRI) and histopathological examination. They were referred across various departments such as dermatology, general surgery and orthopedics, and eventually got correct diagnosis. Treatment was promptly started with oral itraconazole, an antifungal drug, and one patient undergoing additional surgical debulking of the disease which lead to gradual healing of the disease as evident by disappearance of sinuses and return of normal skin in 6-12 months. Conclusion: Madura foot is very characteristic, although it may mimic more prevalent infectious conditions. The characteristic multiple discharging sinuses with extrusions of sulphur granules and MRI findings of "dot in circle" should clinch the diagnosis quickly. Medical therapy should be continued for at least 12 months even if there is resolution of disease in the early or mid-phase of treatment. Debulking of the disease will aid in early recovery and reduce abnormal swelling or appearance of the foot.
RESUMEN
Fibroblasts and myofibroblasts have been known to be present in both ruptured and intact human anterior cruciate ligament (ACL), and although their relevant histology and immunochemistry have been studied in the past, ultrastructural features of these cells are largely lacking. Therefore, we aim to characterise the ultrastructural details of these cells with the help of transmission electron microscopy (TEM) and to study the changes and their significance with duration of injury. Samples from 60 ruptured human ACL undergoing surgery were obtained and categorised according to duration of injury and observed under TEM with main focus on the following ultrastructural features: cellular morphology, presence of rough endoplasmic reticulum, Golgi apparatus, lamina, myofilaments, and presence of myofibroblasts. These features were further correlated with the duration of injury and association, if any, determined using appropriate statistical analysis. A total of 54 male and 6 female patients with mean duration of the injury of 23.01 ± 26.09 weeks (2-108 weeks) were included in the study and categorised into five groups based on duration of injury as follows: I (< 6 weeks), II (7-12 weeks), III (13-20 weeks), IV (21-50 weeks) and V (> 50 weeks). There was a significant association between the above-mentioned ultrastructural features and the duration of injury (p < 0.05) except for the presence of ovoid fibroblast cells (p = 0.53). Furthermore, number of myofibroblasts and cells with Golgi apparatus and rough endoplasmic reticulum was seen to peak at 13-20 weeks following injury. We describe ultrastructural features of fibroblast of different morphology along with myofibroblasts in the ligaments following injury, the changes in which might have a potential bearing on ligament healing.

AIM: To compare the results of arthroscopic capsular release with intra-articular steroid injections in patients of frozen shoulder. METHODS: Fifty-six patients with frozen shoulder were randomised to one of two treatment groups: Group 1, complete 360 degree arthroscopic capsular release and group 2, intra-articular corticosteroid injection (40 mg methyl prednisolone acetate). Both groups were put on active and passive range of motion exercises following the intervention. The outcome parameters were visual analogue scale (VAS) score for pain, range of motion and Constant score which were measured at baseline, 4, 8, 12, 16 and 20 wk after intervention. RESULTS: All the parameters improved in both the groups. The mean VAS score improved significantly more in the group 1 as compared to group 2 at 8 wk. This greater improvement was maintained at 20 wk with P value of 0.007 at 8 wk, 0.006 at 12 wk, 0.006 at 16 wk and 0.019 at 20 wk. The Constant score showed a more significant improvement in group 1 compared to group 2 at 4 wk, which was again maintained at 20 wk with P value of 0.01 at 4, 8, 12 and 16 wk. The gain in abduction movement was statistically significantly more in arthroscopy group with P value of 0.001 at 4, 8, 12, 16 wk and 0.005 at 20 wk. The gain in external rotation was statistically significantly more in arthroscopy group with P value of 0.007 at 4 wk, 0.001 at 8, 12, and 16 wk and 0.003 at 20 wk. There was no statistically significant difference in extension and internal rotation between the two groups at any time. CONCLUSION: Arthroscopic capsular release provides subjective and objective improvement earlier than intra-articular steroid injection.
RESUMEN
BACKGROUND: Double bundle (DB) anterior cruciate ligament (ACL) reconstruction has been proposed to recreate the natural anatomy of ACL. Reconstruction of the anatomy of both the bundles of ACL has been thought to be able to restore the rotational stability of the knee joint. Nevertheless, it remains unclear whether DB reconstruction has better functional outcome than single bundle (SB) ACL reconstruction. PURPOSE: To evaluate the clinical outcomes, patient satisfaction and manual laxity tests of knee in patients treated with DB ACL reconstruction in Indian population. METHODS: We prospectively followed 25 patients with an isolated ACL injury operated for DB ACL reconstruction after applying the inclusion and exclusion criteria. Patients were evaluated pre-operatively and in the post-operative period at regular intervals with the minimum follow up of 4 years. Clinical stability was assessed by anterior drawer test, Lachman test and pivot shift test. Functional outcome was assessed by IKDC, Lysholm and Modified Cincinnati scores. RESULTS: At the end of 4 years, functional outcome in terms of all subjective scores was satisfactory. Graded stability results of the Lachman, Anterior drawer and pivot shift tests were almost near to that in normal knee. No complication occurred post-operatively. CONCLUSION: Anatomical DB ACL reconstruction seems to offer satisfactory results in terms of subjective scores and stability tests to patients with ACL tear. It has been found to be associated with no obvious complications and no failures. However a larger patient pool is desired for conclusive results.
RESUMEN
BACKGROUND: Despite a number of studies comparing postoperative stability and function after anatomic single bundle and double bundle anterior cruciate ligament reconstruction, it remains unclear whether double bundle reconstruction has better functional outcome than single bundle anterior cruciate ligament reconstruction. PURPOSE: To compare the subjective functional outcome as well as clinical stability in patients treated with either anatomic single bundle or anatomic double bundle anterior cruciate ligament (ACL) reconstruction. We hypothesized that there would be no difference in the postoperative functional outcome and clinical stability between anatomical double bundle anterior cruciate ligament reconstructions when compared to single bundle anterior cruciate ligament reconstructions. METHODS: We prospectively followed 40 patients out of which, 20 patients were operated for anatomic single bundle ACL reconstruction and other 20 patients underwent anatomic double bundle ACL reconstruction. Patient evaluation using the laxity tests and outcome scales was done preoperatively and at 12, 24 and 48 months after the surgery. Clinical stability was assessed by Lachman test, Pivot shift test and Delhi active test. Functional outcome was assessed by International Knee Documentation Committee (IKDC), Lysholm and Modified Cincinnati scores. Patients in both groups were evaluated at regular intervals for a minimum period of 48 months (mean 51 months, range 48-56 months). RESULTS: For all subjective scores, double bundle group patients reported statistically significant higher scores compared to single bundle group patients. Graded stability results of the Lachman, and Pivot shift tests were significantly higher in the anatomically reconstructed double bundle patient group. CONCLUSION: We suggest that functional outcome and clinical stability may be better with anatomical double bundle anterior cruciate ligament reconstruction as compared to anatomical single bundle anterior cruciate ligament reconstruction.

Anterior cruciate ligament (ACL) reconstruction with preservation of either the remnant or the tibial stump is performed with the hope of improving the vascularization and proprioceptive function of the graft. Remnant preservation is technically difficult because it hinders the visualization of the intra-articular tunnel site. Taking a cue from the concept of tibial stump preservation, we have modified our ACL reconstruction technique to preserve a sleeve of the soft tissue and ACL stump attached to the femoral condyle, in addition to tibial stump preservation, while still allowing adequate visualization of the femoral ACL insertion site. We describe our modification in this article and hypothesize that this should further improve graft vascularization and ligamentization.
RESUMEN
Ochronotic arthropathy is a rare condition found in patients with alkaptonuria, which is a hereditary metabolic disease associated with deposition the of homogentisic acid derivatives in various connective tissues of the body. We present the case of a 30-year-old woman in whom arthroscopic examination of the left knee prior to meniscectomy for bucket handle tear of medial meniscus revealed brown-black discoloration of the articular cartilage and menisci leading to the diagnosis of alkaptonuria by further laboratory evaluation. After medical and surgical treatment, patient's complaints were alleviated and no further complaints were registered, during the next follow-up.
RESUMEN
Breakage of K-wires and stainless steel wires which are used for fracture fixation is not uncommon, but migration is rare. We report a case of migration of broken K-wire used for patella tension band wiring to the popliteal fossa. The broken hardware was removed surgically. We would like to suggest that K-wire and wire fixation used for treatment of patellar fractures can migrate into the posterior compartment of the knee and cause clinical symptoms. Close clinical and radiological follow-up after internal fixation to identify the presence of hardware breakage or movement and removal of wires once fracture has united can avert such complications.

BACKGROUND: Tears of the medial meniscus posterior root can lead to progressive arthritis, and its management has no consensus. The aim of our study was to evaluate the effect of supervised exercise therapy on patients with medial meniscus posterior root tears. MATERIALS AND METHODS: Between January 2005 and May 2007, 37 patients with this tear verified by magnetic resonance imaging (MRI) and osteoarthritis grade 1-2 by radiographic examination were treated by a short course of analgesics daily for up to 6 weeks and then as required during follow-up, as well as a 12-week supervised exercise program followed by a home exercise program. Final analysis was performed for 33 patients, average age 55.8 (range 50-62) years and average follow-up of 35 (range 26-49) months. Patients were followed up at 3, 6, and 12 months and yearly thereafter using the Lysholm Knee Scoring Scale, Tegner Activity Scale (TAS), and visual analog scale (VAS). The analysis was performed using one-way analysis of variance (ANOVA) and Pearson's correlation coefficient to determine the relationship between Lysholm score and body mass index (BMI). RESULTS: Patients showed an improvement in Lysholm score, TAS, and VAS, which reached maximum in 6 months and later was accompanied by a decline. However, scores at the final follow-up were significantly better than the pretherapy scores. There was also a progression in arthritis as per Kellgren and Lawrence radiographic classification from median 1 preintervention to median 2 at the final follow-up. A correlation between BMI and Lysholm scores was seen (r = 0.47). CONCLUSION: Supervised physical therapy with a short course of analgesics followed by a home-based program results in symptomatic and functional improvement over a short-term follow-up; however, osteoarthritis progression continues and is related to BMI.

PURPOSE: Tubercular infection has not been described, to our knowledge, in the literature after anterior cruciate ligament (ACL) reconstruction, and, hence, the purpose of our case series was to describe our experience, evaluate the clinical and laboratory findings, and assess the treatment outcome. METHODS: We performed a retrospective analysis of 1,152 cases of arthroscopic ACL reconstruction with autografts performed at our institution between January 1998 and May 2007. Tubercular infection was considered to be present in the setting of recurrent negative bacterial cultures but a positive result on microscopy, culture, histopathology, or polymerase chain reaction (PCR). All patients underwent arthroscopic lavage and synovectomy, followed by antitubercular therapy for 12 months. RESULTS: We identified 8 patients (0.69%) with infection. Bone-patellar tendon-bone graft was used in 1 and hamstring graft in 7. All patients were immunocompetent. The mean time from surgery to presentation was 64.4 days (range, 23 to 152 days). Aspirate fluid staining and culture for acid-fast bacilli was negative in all cases, synovial tissue culture was positive in 3, characteristic histopathology was positive in 7, and PCR was positive in 6. A mean of 1.25 surgeries (range, 1 to 2) were performed. The mean length of follow-up in our series was 43.6 months (range, 25 to 73 months), with no reinfections. The mean postoperative Lysholm knee score was 80. CONCLUSIONS: Tubercular infection as a complication after arthroscopic ACL reconstruction, though rare, should be kept in mind as a possible cause of infection in immunocompetent patients in zones endemic for tuberculosis. It should also be kept in mind in nonendemic areas, among immigrants from endemic areas, and in cases with persistent swelling and discharge, effusion with minimal inflammatory signs, and negative cultures. We recommend deoxyribonucleic acid-PCR testing for early diagnosis of tuberculosis. Arthroscopic debridement and antitubercular chemotherapy together are the mainstay of treatment.
