Rotational Shortening of Collateral Ligament in TKR With Severe Deformity.

Instability of the knee joint after total knee replacement (TKR) is one of the most important reasons for revision TKR. Inadequate release or tightening of the collateral ligaments in the knee joint may cause instability and early failure. This study presents a case series study of a new technique for ligament balancing wherein the collateral ligament is detached from its origin and rotated (twisted) around its longitudinal axis to tighten the ligament before the origin is reattached to its original position.

Koebner phenomenon induced by failed revisional orthopedic surgery but remitted with bone union: A case report.

Rationale: Trauma or surgical incision might cause Koebner phenomenon (KP) in patients with cutaneous diseases, but seldom studies reported KP induced by repeated orthopedic surgery.

Patient Concerns: The 22-year-old man did not have any prior histories of cutaneous diseases. Two months after the revision surgery for nonunion of the left femoral shaft fracture, KP was noted by psoriasis presented at the surgical scar, left thigh, scalp, and trunk.

Lung cancer with solitary bone metastasis in the radius.

We present a 73-year-old man with a new diagnosis of right upper lung adenocarcinoma. Right elbow x-ray and Tc-99m MDP whole body bone scan were performed due to a reddish, swollen, and painful right forearm for 1 week. X-ray, performed on March 25, 2008, showed an osteolytic lesion in the proximal right radius with surrounding soft tissue swelling.
