INTRODUCTION Assessment of soft-tissue balance by the gap technique in Total Knee Arthroplasty (TKA) impacts femoral component rotation positioning. Proper femoral component rotation is a critical factor in TKA, both for adequate patellar tracking and in achieving a symmetrical flexion gap. Soft tissue balance assessment and gap measurements are performed at 90° flexion and with the patella eve...

INTRODUCTION Locked vertical patellar dislocations are rare and pose a therapeutic challenge. This case is more unusual, as the patient was a known case of recurrent patellar dislocation and presented with an atraumatic locked and vertically rotated patellar dislocation. This type of presentation has never been reported in literature to the best of our knowledge. CASE PRESENTATION A 14-year-o...

In recent years, the medial patellofemoral ligament (MPFL) has been considered as the primary restraint of the medial patellar stabilizers [1]. Clinical reports have revealed that MPFL injury occurs in almost all patients with traumatic patellar dislocation, and attention has been focused on the repair and reconstruction of the MPFL in recurrent patellar dislocation and patellar subluxation [2]...

: Intrusion is the most severe luxation injury, resulting in soft and hard tissue damage. Treatment depends on root development stage tooth intrusion degree. Lateral describes displacement any direction other than axial. The prognosis of luxated teeth emergency treatment elapsed time. This paper reports an 11-year-old boy who sustained central lateral incisors into nasal cavity, his left canine...

Avulsion and intrusive luxation are two severe and complicated types of dental trauma. Combination of these two types of injury is rare in the literature because they vary in terms of underlying mechanism of occurrence. This case report describes the management of an unusual traumatic injury of two permanent maxillary central incisors with avulsion and intrusive luxation concomitantly. The pati...

Patellar tendon rupture is a catastrophic complication following total knee arthroplasty (TKA). Though revision TKA has been suspected of being a predisposing factor for the occurrence of patellar tendon rupture, there are few reports on patellar tendon rupture after revision TKA. Here, we present a case of acute patellar tendon rupture that occurred after TKA revision. In the patient, the pate...
