Randomized Controlled TrialComparison of cementless twin-peg, cemented twin-peg and cemented single-peg femoral component migration after medial unicompartmental knee replacement: a 5-year randomized RSA study.
The component design and fixation method of joint arthroplasty may affect component migration and survival. The aim of this study was to compare fixation of cementless twin-peg (CLTP), cemented twin-peg (CTP) and cemented single-peg (CSP) femoral components of medial unicompartmental knee replacement (UKR). ⋯ At 5-year follow-up, fixation of UKA femoral components with twin-peg was not superior to the single-peg design. Cementless and cemented twin-peg femoral components had similar fixation. A lower flexion angle was correlated with higher component migration.

Randomized Controlled TrialHigher intra-operative narcotic requirements and weakness with quadratus lumborum compared to paravertebral nerve block for total hip arthroplasty.
This was a prospective single-blinded study comparing the peri-operative opioid consumption and motor weakness for patients undergoing total hip arthroplasty (THA) with either a Quadratus Lumborum Type 3 Nerve Block (QLB) or a Paravertebral Nerve Block (PVB). ⋯ III, Non-randomized controlled cohort/follow-up study.

Randomized Controlled TrialOxycodone-acetaminophen versus celecoxib for postoperative pain in knee osteoarthritis patients after total knee arthroplasty: a randomized, controlled study.
Oxycodone-acetaminophen is a synergic combination of semisynthetic opioid agonis and analgesic/antipyretic agent, which improves analgesic efficacy. This randomized, controlled study intended to evaluate the analgesic efficacy and tolerance of oxycodone-acetaminophen compared to celecoxib alone in post-total knee arthroplasty (TKA) knee osteoarthritis patients. ⋯ Oxycodone-acetaminophen exerts superior analgesic efficacy, patients' satisfaction, and similar tolerance compared to celecoxib in post-TKA knee osteoarthritis patients.

Randomized Controlled TrialSingle-injection nerve blocks for total knee arthroplasty: femoral nerve block versus femoral triangle block versus adductor canal block-a randomized controlled double-blinded trial.
Femoral nerve block (FNB) is a well-established analgesic technique for TKA. However, it associates quadriceps weakness. Therefore, femoral triangle block (FTB) and adductor canal block (ACB) were proposed as effective alternative motor-spearing techniques. The primary objective was to compare quadriceps muscle strength preservation between FNB, FTB and ACB in TKA. The secondary objective was to analyze pain control and functional outcomes. ⋯ This study was registered in clinicaltrials.gov (NCT03518450; https://clinicaltrials.gov/ct2/show/NCT03518450 ; submitted March 17, 2018).

Randomized Controlled TrialPostoperative rehabilitation using a digital healthcare system in patients with total knee arthroplasty: a randomized controlled trial.
Digital healthcare systems based on augmented reality (AR) show promise for postoperative rehabilitation. We compared the effectiveness of AR-based rehabilitation and conventional rehabilitation after total knee arthroplasty (TKA). ⋯ The use of a digital healthcare system based on AR improved the functional outcomes, pain, and quality of life of patients after TKA. AR-based rehabilitation may be useful treatment as an alternative to conventional rehabilitation.
