Although the severity of knee osteoarthritis (OA) usually is assessed using different measures of joint structure, function, and pain, the relationships between these measures are unclear.
All-Polyethylene Tibial Components in Obese Patients Are Associated With Low Failure at Midterm Followup
In the United States, the obese population has increased markedly over the last four decades, and this trend continues. High patient weight places additional stress on TKA components, which may lead to increased polyethylene wear, osteolysis, radiolucencies, and clinical failure. Metal-backed tibial components and all-polyethylene tibial components in the general population have comparable osteolysis and failure, but it is unclear whether these components yield similar osteolysis and failure in obese patients.
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.
Early studies in the literature reported relatively high early minor reintervention rate for the mobile-bearing unilateral knee arthroplasty (UKA) compared with short- and midterm survivorship after fixed- or mobile-bearing UKA. However, whether the long-term function and survivorship are similar is unclear.
Decreased Length of Stay After TKA Is Not Associated With Increased Readmission Rates in a National Medicare Sample
There is a trend toward decreasing length of hospital stay (LOS) after TKA although it is unclear whether this trend is detrimental to the overall postoperative course. Such information is important for future decisions related to cost containment.
Young, active, skeletally mature patients have higher failure rates after various surgical procedures, including stabilization for shoulder instability and primary ACL reconstruction. It is unclear whether young, active, skeletally mature patients share similarly high failure rates after revision ACL reconstruction.
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.
We developed the rectangular tunnel ACL reconstruction (RT ACLR) using a 10-mm wide bone-patellar tendon-bone (BTB) graft through rectangular tunnels with a rectangular aperture to reduce tunnel size: the cross-sectional area of the tunnels of 50 mm(5 × 10 mm) in RT ACLR is less than that of 79 mmin a conventional 10-mm round tunnel technique presuming the technique would be more suitable in revision ACLR with previous improperly placed tunnels.
Surgical Technique: Medial Collateral Ligament Reconstruction Using Achilles Allograft for Combined Knee Ligament Injury
Previous approaches for medial collateral ligament (MCL) reconstruction have been associated with extensive exposure, risk of donor site morbidity with autografts, loss of motion, nonanatomic graft placement, and technical complexity with double-bundle constructs. Therefore, we implemented a technique that uses Achilles allograft, small incisions, and anatomic insertions to reconstruct the MCL.
Single- versus Double-bundle ACL Reconstruction: Is There Any Difference in Stability and Function at 3-year Followup?
Despite a number of studies comparing postoperative stability and function after anatomic double-bundle and single-bundle anterior cruciate ligament reconstruction (ACLR), it remains unclear whether double-bundle reconstruction improves stability or function.
