Lateral unicompartmental knee arthroplasty relieves pain and improves function in posttraumatic osteoarthritis.
Posttraumatic arthritis secondary to lateral tibial plateau fracture malunion causes pain and limited function for patients. It is sometimes technically challenging to correct malalignment in these patients with advanced arthritis using osteotomies. Lateral unicompartmental knee arthroplasty (UKA) may be an option to treat such patients. ⋯ Despite the limited number of indications and technical considerations, our observations suggest lateral UKA is a reasonable option for treating lateral arthritis secondary to malunited fractures.

Incidence of deep vein thrombosis and pulmonary embolism after Achilles tendon rupture.
The use of venous thromboembolism prophylaxis after an Achilles rupture is controversial. The rates of reported deep vein thrombosis (DVT) range from 6.3% to 34%. There is no agreement regarding prophylactic therapy after an Achilles tendon rupture. ⋯ We found the overall incidence of symptomatic DVT and PE to be low after an Achilles tendon rupture and believe routine use of anticoagulation might be unwarranted.

Comparative StudyPatient-related risk factors for postoperative mortality and periprosthetic joint infection in medicare patients undergoing TKA.
The impact of specific baseline comorbid conditions on the relative risk of postoperative mortality and periprosthetic joint infection (PJI) in elderly patients undergoing TKA has not been well defined. ⋯ We believe this information important when counseling elderly patients regarding the risks of mortality and PJI after TKA and risk-adjusting publicly reported TKA patient outcomes.

Comparative StudyPreoperative patient education reduces in-hospital falls after total knee arthroplasty.
Inpatient hospital falls after orthopaedic surgery represent a major problem, with rates of about one to three falls per 1000 patient days. These falls result in substantial morbidity for the patient and liability for the institution. ⋯ Inpatient falls after TKA may be associated with major complications. Our preoperative patient education reduced these falls and is now mandatory for patients undergoing TKA at our institution.

Comparative StudyRestoration of the distal femur impacts patellar height in revision TKA.
Restoring patellar height is important in revision TKA for normal knee function and kinematics. Alteration in patellar height after revision TKA is associated with inferior extensor mechanism function. ⋯ Surgeons can maintain normal patellar height and improve patella baja by preserving bone stock and using distal femoral augments to restore the distal joint line during revision TKA.
