Using a Markerless Motion Capture System to Identify Preinjury Differences in Functional Assessments.

Functional assessments identify biomechanical issues which may indicate risk for injury and can be used to monitor functional recovery after an injury or surgery. Although the gold standard to assess functional movements is marker-based motion capture systems, these are cost prohibitive and have high participant burden. As such, this study was conducted to determine if a markerless motion capture system could detect preinjury differences in functional movements between those who did and did not experience a noncontact lower extremity injury (NCLEI).

Minimally Invasive Knee Lateral Collateral Ligament Reconstruction Using Partial Biceps Femoris Tendon Autograft.

Lateral collateral ligament (LCL) is known as an important ligament to restrain varus force of the knee, especially in 30° knee flexion. From the anatomical study, the insertion of LCL at proximal fibula is intimately close to the insertion of biceps femoris (BF) tendon. Since LCL is infrequently injured in isolation, and with limitation in availability of autograft and allograft, this study proposes the partial anterior BF tendon as an alternative autograft source to reconstruct the LCL.

Hybrid Inside-Out-Outside-In Meniscal Repair Through a Small Skin Incision.

Although the updated generation of all-inside devices for meniscal repair is more convenient to deploy and can provide comparable clinical outcomes with those of the inside-out procedure, the latter is still a very useful technique, giving many advantages over the former. The critical drawback of the conventional inside-out technique is the need for preparation of the accessory incision to prevent the risk of soft-tissue entrapment and neurovascular injury while retrieving the exiting meniscal needles, especially at the posterior corner of the knee. To minimize the space volume of the incision, a small, bluntly dissected track guided by the first exiting meniscal needle is sufficient in our hybrid inside-out-outside-in technique.

A comparative study comparing area of extension of posterior knee capsule via posteromedial injection: a cadaveric study.

Background: Periarticular multimodal drug injection (PMDI) has gained popularity as common postoperative pain protocols in knee arthroplasty. PMDI sites can vary, but posterior capsule (PC) is a common injection site because of its abundance of pain nociceptors.

Purpose: To prove the hypothesis whether posteromedial drug injection alone is sufficient to provide enough effect covering the PC in order to reduce risks of neurovascular injury.

Prognostic and risk factors in patients with metastatic bone disease of an upper extremity.

Background: The aim of this study was to evaluate survival of metastatic bone disease of an upper extremity, and to identify the prognostic factors that influence survival.

Methods: Patients with metastatic bone disease of an upper extremity between 2008 and 2015 were reviewed from the database of a tertiary university hospital.

Results: Of 102 patients, 48 males and 54 females with a median age of 61 (range, 28-82 years), the humerus (64.
