Posterior stability in posterior-stabilized vs medially congruent total knee replacement: A radiological comparison of two polyethylene designs in a single model
Objective:The purpose of this radiological study was to assess the posterior laxity of a single model of a total knee arthroplasty design (TKA) having a medially constrained (MC) or a Posterior-Stabilized (PS) polyethylene insert using a well-documented stress x-ray. To the authors knowledge, this is the first report evaluating MC TKA outcomes according to the “kneeling view.”Materials and Methods:Sixty patients with non-traumatic primary knee osteoarthritis undergoing TKA were first matched by age, sex, BMI and diagnosis and then divided in two groups: group A (37 knees) received a MC TKA and group B (23 knees) a PS implant made by the same manufacturer. In all cases the posterior cruciate…
Intramuscular tramadol versus ketorolac in patients with orthopedic and traumatologic postoperative pain: a comparative multicenter trial
This 3-day, multicenter, open-label, randomized, controlled trial was undertaken to assess the postoperative analgesic effect and therapeutic safety of intramuscular tramadol compared with intramuscular ketorolac in 48 patients undergoing orthopedic surgery and having postoperative pain assessed as 75 mm or more on a 100-mm visual analogue scale. Tramadol (100 mg/2 mL ampules) was administered as needed to a maximum of 400 mg/d, and ketorolac (30 mg/1 mL ampules) was given as needed up to 90 mg/d. Nine patients who received tramadol and six who received ketorolac needed only one dose of medication to achieve satisfactory analgesia. Tramadol had a more pronounced analgesic effect than did ke…
