Randomized Controlled Trial Comparative StudyIs There an Advantage to Knotless Barbed Suture in TKA Wound Closure? A Randomized Trial in Simultaneous Bilateral TKAs.
Effective wound closure is critical to minimizing wound complications and withstanding the forces associated with early knee motion after TKA. Barbed sutures allow for knotless fixation, have been used successfully in other specialties, and may provide for more even distribution of tension along the length of the incision; however, data regarding unidirectional barbed sutures from randomized trials have raised important concerns about their use. Bidirectional barbed sutures offer a potential alternative, but have not been studied extensively in orthopaedic surgery. ⋯ Level I, therapeutic study.

ReviewDoes surgical timing influence functional recovery after lumbar discectomy? A systematic review.
The impact of the duration of preoperative symptoms on outcomes after lumbar discectomy has not been sufficiently answered in a single study but is a potentially important clinical variable. ⋯ Longer symptom duration had an adverse impact on results in most studies after lumbar discectomy. A possible point beyond which outcomes may be compromised is 6 months after symptom onset. Limitations in the literature surveyed, however, prevent firm conclusions.
