Introduction: Synovial chondromatosis of the knee is an unusual, rare, benign metaplastic neoplasm of the synovium, characterized by the formation of focal cartilaginous nodules in the synovium. It predominantly involves the anterior compartment of knee and extensive, disseminated involvement is rarely reported. Diagnosis is usually established with clinicoradiological imaging and confirmed by histology. The paucity of literature on the management of synovial chondromatosis puts an orthopedician in dilemma regarding the optimal surgical intervention. Case Report: We report a case of 50-year-old male who presented with severe pain and swelling in his left knee associated with functional incapacitation. Magnetic resonance imaging demonstrated diffuse proliferation of synovium with mild effusion displaying multiple, disseminated calcific nodules. We managed the case by open removal of loose bodies and radical synovectomy through combined anterior and posterior approach. At 4 years follow-up, there are no clinical or radiological signs of recurrence. Conclusion: Extensive involvement of the knee with calcific nodules is extremely rare. Treatment is controversial which usually includes removal of loose bodies combined with an open or arthroscopic synovectomy. Our case report recommends single stage, open retrieval of loose bodies combined with radical synovectomy to decrease the incidence of recurrence in extensive synovial chondromatosis. To the best of our knowledge, disseminated synovial chondromatosis of the knee, managed by open, combined approach, has been reported only once in the literature.

Background Lateral elbow tendinopathy (LET) has an array of modalities described for its management. The present study analyzed two modalities used for managing the condition. Methods The present study included 64 non-athletes with LET who failed conservative treatment that included avoiding strenuous activities, ice-fomentation, non-steroidal anti-inflammatory drugs, bracing, and physiotherapy for 6 months. A random allocation of the participants was done, with one group injected with platelet-rich plasma (PRP) and the other group with corticosteroids. The procedure was performed by the same blinded orthopedic surgeon after localizing the pathology using ultrasound. Visual analog scale (VAS) scores, disabilities of the arm, shoulder and hand (DASH) scores, Patient-Rated Tennis Elbow Evaluation (PRTEE) scores, and handgrip strengths were recorded by blinded observers other than the surgeon administering the injection. Results The average age of the patients was 40 years. The mean VAS score at the latest follow-up of 2 years in the PRP group was 1.25 and it was significantly better than the score of 3.68 in the steroid group ( p < 0.001). The mean DASH score at the latest follow-up of 2 years in the PRP group was 4.00 and it was significantly better than the score of 7.43 in the steroid group ( p < 0.001). The mean PRTEE score at the latest follow-up of 2 years in the PRP group was 3.96 and it was significantly better than the score of 7.53 in the steroid group ( p < 0.001). The scores were better in the steroid group at a short-term follow-up of 3 months ( p < 0.05), while they were better in the PRP group at a long-term follow-up of 2 years ( p < 0.05). Hand-grip strength was comparable in the PRP group (84.43 kg force) and steroid group (76.71 kg force) at the end of the 2-year follow-up with no statistically significant difference ( p = 0.149). Conclusions Corticosteroid injections alleviated symptoms of LET over short-term follow-up providing quicker symptomatic relief; however, the effect faded off over the long term. PRP injections provided a more gradual but sustained improvement over the long-term follow-up, indicating the biological healing potential of PRP.

Introduction: Hibernoma is an uncommon benign tumor composed of multivacuolated brown adipocytes described in the literature a decade back. Intraosseous hibernomas are extremely rare with propensity to affect axial skeleton. Involvement of appendicular skeleton has been reported only twice in the literature till date. Case Report: We present a case of solitary, painless mass in the left proximal tibia mimicking neoplasm in a 35-year-old male. The plain radiographs revealed a lytic lesion with well-defined margin at the junction of metaphyseal-diaphyseal region of the left proximal tibia. The lesion was hyperintense on T2 and hypointense on T1 with heterogenous enhancement on contrast imaging. FDG-PET showed high uptake of fluorodeoxyglucose. Histopathological examination revealed the presence of multivacuolated cytoplasm with abundant mitochondria suggestive of hibernoma. On immunohistochemistry, the cells were positive for S-100. Conclusion: The findings of imaging modalities are non-specific and histopathological examination is required to confirm the diagnosis of hibernoma. Intraosseous hibernoma needs to be considered as a differential diagnosis of sclerotic bone lesion. Further, evaluation with regular follow-up with imaging will be required if the mass undergoes any clinical changes. Both radiologists and pathologists, need to be aware of this rare entity to avoid misdiagnosis of the uncommon lesion.

Background: We analyzed the clinical and radiological parameters influencing functional outcomes and neurological recovery in patients with cervicothoracic junctional tuberculosis (TB). Methods: This was a retrospective analysis of 16 cases of cervicothoracic junction (CTJ) spinal TB; 11 patients were managed operatively, while five were managed conservatively. Patients’ outcomes were assessed at 1 month, 1 year, and yearly thereafter and included an analysis of multiple outcome scores, various radiographic parameters, and sensitivity or resistance to anti-tubercular therapy. Results: Patients averaged 25.94 years of age, and typically had three-level vertebral involvement. They were followed for a mean duration of 24 months, and the duration of anti-tubercular therapy averaged 17 months. Patients demonstrated clinical improvement on Japanese Orthopedic Association score and Neck disability index (P < 0.005) starting from 1 month following initiation of treatment which continued in subsequent follow-up, along with change in radiological parameters consisting of mean segmental kyphotic angle from 18.98° to 15.13°, C2–C7 SVA from 16.13 mm to 22.61 mm, T1 slope from 22.80° to 14.66°, thoracic inlet angle from 75.35° to 63.25°, neck tilt from 51.81° to 48.33°, and cervical lordosis from 4.66° to −0.44° (P > 0.05) at the end of 1 year. Conclusion: Tuberculous affection of the dynamic CTJ is a challenging scenario in clinical practice and its management involves consideration of disease extent, neurological status, and effort toward restoration of normal alignment of spine in sagittal and coronal plane to get favorable clinical outcomes.
