Abstract

Background: Variation in the shape of the femur and tibia has been shown to influence hip–kneeankle-axis angle (HKAA) and bears a role in reconstructive surgeries such as total knee arthroplasty (TKA). However, data on the axial alignment of the lower extremity specific to sex largely remains unavailable. Thus, we conducted a study with an aim to measure alignment and calculate differences in both the sexes in Indian population. Materials and Methods: The following radiological parameters were measured from weight-bearing long leg radiographs of 966 limbs of Indian subjects via a morphometric software (Matlab R2009a) (1) Hip–Knee–Ankle angle (HKAA), (2) femoral bowing, (3) tibial bowing, (4) condylar plateau angle (CPA). The knees were classified according to the Kellegren and Lawrence grading and the differences between both the sexes were calculated with appropriate statistical tests. Results: 56.04% of the subjects were female. An increase in the mean age was observed for both the genders with an increase in the severity of OA. Height did not show any significant association with the alignment of the limb. The mean HKAA observed was − 5.88° ± 0.35° in females and − 4.99° ± 0.41° in males. The overall mean femoral bow and tibial bow was − 1.26° ± 0.24°, − 1.60° ± 0.18° in females and − 1.09 ± 0.28, − 1.47° ± 0.21° in males. The mean condylar plateau angle was higher in females − 2.67 ± 0.34 as compared to males − 2.35° ± 0.39°. A greater lateral bow was seen in males at higher grades of OA for femur and at lower grades of OA for tibia. Conclusion: This study provides gender-based differences in the various axial radio-graphic parameters in a long leg radio-graphs in Indian population which might help in a better understanding of the etiopathogenesis of osteoarthritis and also help planning and execution of reconstructive surgeries such as TKA.

Abstract

Patellar tendinopathy is also known as “Jumper’s knee” and is a common cause of impaired function in athletes who participate in sports that require jumping and running activities. The exact etiology of disease is still unknown and several theories have been postulated for its pathogenesis. It usually presents as anterior knee pain that is related to the sports activity and might lead to decreased sports participation. USG and MRI are the main modality of investigation that aids in the diagnosis. Non-operative therapy forms the main stay of treatment in form of rest, brace, physical therapy and anti-inflammatory medications. Other adjuncts such as cryotherapy, corticosteroids injection, platelet -rich plasma injections and electrical therapy like TENS or ESWT have been used with some success. Operative intervention in form of open or arthroscopic procedures are reserved for chronic and refractory cases.

Abstract

Peroneal nerve injuries have been reported in association with various causes around the knee such as traumatic varus injury, traumatic dislocation, upper tibial osteotomy, knee arthroscopy and total knee arthroplasty. Two instances of varus arthritic knee associated with a peroneal nerve palsy have been reported so far. One presented with gradual onset peroneal nerve palsy that recovered with time and the other with sudden onset peroneal nerve palsy that did not recover. We describe the case of a 63-year-old man who presented with a symptomatic varus arthritic knee and sudden onset peroneal nerve palsy with synovial cysts over the lateral aspect of the knee. We performed a total knee arthroplasty with decompression of the synovial cyst in the same patient. Three months following the surgery the patient was walking pain free with a completely recovered nerve palsy.

24. An Unusual Case of Huge Tophaceous Pseudogout Mimicking as a Tumor-Like Lesion around the Ankle Joint: A Case Report and Literature Review

Abstract

Pseudogout or calcium pyrophosphate dihydrate deposition disease (CPPD) primarily affects the joints and the periarticular tissues. Tophaceous or tumoral pseudogout is a rare form of this disease which is seen around the joints of extremities. It can be misdiagnosed as a neoplastic condition because of its clinicoradiological similarities, and thus, a proper histopathological examination is indispensable. We report one such case of extra-articular deposition of the CPPD crystals in a 65-year-old man who presented with an asymptomatic swelling around the left ankle. Radiographs showed a dense homogenous calcification, and FNAC revealed dense calcium deposits with numerous rhomboid-shaped crystals. It was managed by en bloc excision, and postoperative biopsy reports confirmed the diagnosis. Possibility of pseudogout should be kept as a differential diagnosis in patients presenting with calcified soft tissue swellings and should be subjected to a detailed histopathological examination for confirmation.

Abstract

Purpose: This study aimed to investigate the alignment based on deformity in knees affected by osteoarthritis (OA) at different stages and evaluate its association with OA., Material and Methods: The following radiological parameters were measured from weight bearing long leg radiographs of 966 legs in the Indian subjects via a morphometric software (Matlab R2009a) (1)Hip-Knee-Ankle angle (HKAA), (2) Femoral bowing, (3) Tibial Bowing, (4) Condylar Plateau angle (CPA). The knees were classified according to the Kellegren and Lawrence grading and these parameters were evaluated with OA for its association using appropriate statistical tests., Results: The mean HKAA angle was 174.5° ±6.5°, 65.8% of the limbs were in found to be in varus (<177°) and 3.8% in valgus (>183°). The mean femoral and tibial bowing was -1.19 ± 4.95° and -1.54 ± 3.58° respectively. 55.8% of femorae and 41.4% of the tibia were observed to have varus bowing while 24.12% of femorae and 12.11% the tibia were observed to have valgus bowing. An increase in odds of disease severity was observed with femoral and tibial bowing >2°. With an increase in the grades of OA a significant increase in the lateral bow of both femur and tibia was observed. The mean condylar plateau angle was observed to be -2.53° ±7.9°. Positive association was seen between the varus CPA, HKA and OA (p < 0.01 )., Conclusion: This study describes the various radiological parameters in Indian patients at different grades of OA and might elucidate the role of these factors in OA initiation and progression., Competing Interests: All authors have no potential conflicts of interest, including financial interests, activities, relationships, and affiliations, to disclose., (© 2019 Professor P K Surendran Memorial Education Foundation.
