Septic arthritis is an infection of the joint space that can lead to joint destruction, disability, and death. Mortality risk is increased by old age, comorbidities such as decreased kidney function, and involvement of multiple joints. We report a rare case of bilateral septic arthritis of the wrists in a 101-year-old woman who recovered without complications. This case illustrates the necessity of monitoring pain in other joints in cases of monoarticular septic arthritis to rule out polyarticular involvement to prevent long-term complications, morbidity, and mortality.

A 23-year-old man presented to the orthopaedic clinic with chronic thigh pain 5 years after a sprinting injury with weakness and deformity. He was found to have a distal rectus femoris tendon rupture with 20 cm of retraction. An onlay reconstruction was performed using peroneus longus and achilles allografts, and the patient regained full strength and range of motion 1 year postoperatively. Chronic ruptures of the rectus femoris tendon are poorly described in the literature. Retraction may require use of allograft tissue to improve extensor mechanism function. Although outcomes may be improved postoperatively, expectation management is paramount for high demand patients.

A 66-year-old woman, former bodybuilder with right sternoclavicular (SC) arthritis managed with a 4-cm proximal clavicle (PC) resection, that led to scapulothoracic abnormal mobility (STAM), severe loss of shoulder function, and pain. A novel reconstruction involving a humeral allograft with a semitendinosus allograft for SC stabilization was performed. A 3-year follow-up is presented with satisfactory outcome. PC overresection in the management of SC joint pathology without ligament reconstruction may lead to severe STAM. Restoring clavicular length with a cortical allograft combined with a tendon reconstruction of the SC joint can yield a successful outcome.

An 88-year-old woman presented with worsening right hip pain over 2 years. Radiographs were unremarkable, but magnetic resonance imaging identified a femoral neck lesion. A computed tomography-guided biopsy revealed a zellballen pattern of cells positive for chromogranin and synaptophysin. Further workup, including a metaiodobenzylguanidine scan confirmed focal uptake at the right femoral neck. After multidisciplinary discussion, and shared decision-making with the patient, conservative management was chosen. Primary intraosseous paragangliomas are rare, with this case representing only the second reported in femur and third in the appendicular skeleton. It underscores the importance of a multimodal diagnostic approach, individualized treatment plans, and multidisciplinary collaboration.

An 11-year-old girl presented with left knee pain after a fall. Imaging revealed bilateral superior osteochondrosis of the patella with a superimposed fracture of the superior third portion of the left patella. The patient underwent open reduction and internal fixation of the fracture. At the 1-year follow-up, imaging showed healing of the left patella fracture and near resolution of the osteochondrosis. There was minimal ossification and continued pain symptoms in the right knee during physical activity. This case highlights the presentation and subsequent management of a rare pediatric superior osteochondrosis of the patella, not previously accounted for in classification schemes.

We present a case of an intra-articular transverse glenoid fracture in an 11-year-old boy who fell while doing a handstand. An arthroscopic shoulder approach was used to reduce and fixate the fracture with 2 knotless anchors and a headless compression screw. The patient achieved full range of motion within 6 weeks and resumed sports activities at 2 months after the procedure. Fracture-dislocation of the glenoid fossa is an uncommon injury that can be effectively treated by arthroscopic fixation. To our knowledge, there are no reported cases of arthroscopic fixation of a glenoid fracture of a pediatric patient.

This case discusses the reimplantation of a comminuted osteochondral fracture of the lateral talar dome with 1 large extruded fragment in a 19-year-old man after a low-energy motor vehicle accident. The fragment transport and decontamination protocols are detailed and the patient's return to full, pain-free range of motion at 18-month follow-up with no radiographic signs of arthritis. To our knowledge, this is the only case describing reimplantation of an extruded osteochondral fracture fragment that also provides a surgical technique and anticipatory guidance for patients and providers in regard to short-term postoperative outcomes.

A 59-year-old man presented 18 months following bilateral total hip arthroplasty (THA) with ceramic-on-polyethylene bearings through the direct anterior approach, with progressive bilateral groin pain and swellings around his upper thighs since 2 months. He was advised surgery considering the possibility of a periprosthetic joint infection. Intraoperatively, large pedunculated periprosthetic synovial cysts were noted bilaterally. They were excised en masse, and the resulting defects were repaired. At 15 months following surgery, he had no recurrence of symptoms. The possibility of periprosthetic cystic lesions must be considered in the differential diagnosis of inexplicable pain following THA.

A 75-year-old woman underwent cruciate retaining total knee arthroplasty (TKA) for osteonecrosis of the knee, converted from unicompartmental arthroplasty due to an intraoperative medial tibial plateau fracture. Four years later, she experienced persistent knee pain. Computed tomography revealed tibial malalignments in 2 planes. In vivo kinematic analysis using single-plane fluoroscopy, which can visualize the femorotibial contact, indicated varus thrust with lateral subluxation of the tibial component and the femoral component recessing into the polyethylene insert. Revision TKA affirmed the polyethylene insert breakage. Malalignment might have caused mechanical failure, and in vivo kinematic analysis was useful to visualize abnormal kinematics in TKA.

We report a rare case of successful reimplantation of a 35-cm extruded femoral bone segment, including the articular portion, following trauma, which is the largest reported reimplanted bone segment to date. Meticulous debridement and soaking in antibiotics prepared the bone for reimplantation and preserved the bone's osteoinductive properties, which may have played a role in structural and functional recovery. This case highlights the feasibility of reimplanting large bone segments with articular components, offering a viable approach for orthopaedic reconstructions.
