The aim of the article is to identify demographic and intraoperative factors that predict patient-oriented outcomes as measured by knee-specific and general quality of life (QoL) questionnaires for chronic, unilateral primary anterior cruciate ligament (ACL) tears following surgical reconstruction. A total of 69 patients were prospectively evaluated using the Medical Outcomes Study 36-item Short Form (SF-36), modified Lysholm, Tegner activity level, and subjective portion of the International Knee Documentation Committee (IKDC) questionnaires. The surveys were administered preoperatively and postoperatively with a minimum 2-year follow up. ⋯ QoL and knee function were improved following ACL reconstruction for chronic ACL tears. Independent predictors of poorer outcome were identified in the PF, bodily pain, and physical component score (PCS) of the SF-36. Increasingly, severe articular cartilage injury to the medial and patellofemoral compartments, as well as the presence of a lateral meniscal tear were predictive of poorer outcomes.

Patellofemoral instability can be a disabling problem. Numerous techniques are employed for its treatment. Medial patellofemoral ligament (MPFL) reconstruction in combination with other procedures has been explored by many orthopedic surgeons. ⋯ The series mean IKDC scores at follow-up was 76.3 ± 19.2 (range, 30-99), and Tegner activity scores were 5.6 ± 2.5. MPFL reconstruction is an option for treating the symptoms of patellar instability, preventing recurrent dislocation, and returning patients near to their preinjury level of activity. The level of evidence is IV.

Methods of tibial plateau fracture fixation have evolved over the last decades; however the techniques used to reduce these fractures have remained relatively unchanged. Balloon tibioplasty, a minimally invasive novel technique used in the reduction of depressed tibial plateau fractures, has been gaining popularity. ⋯ Although an attractive option, as with all novel techniques there is a learning curve. The purpose of this article is to briefly describe our technique of balloon tibioplasty, potential contraindications, and to illustrate some possible complications, and provide some tips and tricks we have found useful to avoid them.

Tumors of the peripheral nerve sheath including schwannomas are known for their rarity and can present with neurological deficit. We report an interesting case of schwannoma of the infrapatellar branch of saphenous nerve presenting with anteromedial knee pain and proximal tibial metaphyseal defect. A 26-year-old man presented with pain and swelling (for the past 2 months) in the anteromedial aspect of knee. ⋯ Histopathological examination confirmed benign schwannoma and the patient became symptom-free after the surgery. Schwannoma of the infrapatellar branch of saphenous nerve can present with anteromedial knee pain. In patients with an eccentrically placed metaphyseal defect of the anteromedial tibia with sclerosed smooth margins, the possibility of nerve sheath tumors should always be considered.

Primary or revision total knee arthroplasties (TKAs) may be associated with a marked amount of intraoperative or postoperative blood loss that potentially may lead to the need for blood transfusions. However, Jehovah's Witnesses usually refuse blood transfusions because of their religious beliefs. ⋯ In this report, we provide an overview of various potential preoperative, intraoperative, and postoperative blood management measures that may be used for the care of Jehovah's Witnesses who undergo knee arthroplasty procedures. In addition, we review reported outcomes of primary and revision TKAs in these patients.
