Comparison of 1-year outcomes between MAKO versus NAVIO robot-assisted medial UKA: nonrandomized, prospective, comparative study.

Background: We have conducted a prospective cohort study with the aim of comparing operative time, intraoperative blood loss, and radiologic and clinical outcomes between imageless (NAVIO) and image-based (MAKO) robot-assisted unicompartmental knee arthroplasty (UKA) for medial compartment osteoarthritis (OA) of the knee.

Methods: A total of 33 patients with medial compartment OA of the knee were prospectively allocated on alternate operative days of their surgery to MAKO (16 patients) or NAVIO (17 patients) robot-assisted UKA. The primary outcome (Knee Society Score [KSS] and Knee Functional Score [KFS]) and the secondary outcomes (intraoperative time of seven steps [registration of hip and ankle, femur and tibia, ligament tension, implant planning, preparation femur, tibia and trial implant], component alignment [coronal and sagittal of femur, tibia implant], blood loss, complications, and revision at 1 year after surgery) were compared between two groups.

A Ten to Thirteen Years Follow-up and Survivorship Study Cemented Low Contact Stress (LCS) Total Knee Replacement in Thailand.

Objective: The Low Contact Stress (LCS) rotating platform mobile-bearing knee replacement is a leading, worldwide, knee replacement system, but has not been the subject of long-term clinical and/or radiographic follow-up studies evaluating the device in Thailand. The purpose of the present study was to report the 13-year results of a consecutive series of patients who have had primary total knee replacement performed implanting the LCS devices by a single surgeon, Leelasestaporn C.

Material And Method: Between May 1999 and December 2002, the author performed 161 consecutive total knee arthroplasties in 138 patients with LCS rotating-platform device by the Ethic Committee approval.

Prospective non-randomized comparative clinical outcome of computer assisted total knee arthroplasty with and without a minimally invasive approach.

Objective: Compare clinical outcomes of computer assisted total knee arthroplasty using the LCS knee implant with (CAMITKA) and without (CATKA) minimally invasive surgery.

Material And Method: The author prospectively performed 71 computer-assisted total knee arthroplasties (TKA) in group of the present study using the Ci navigation system in a non-randomized manner.

Results: CAMITKA subjects had a mean operation time of 105 minutes, average incision length of 9.

Comparative mechanical axis deviation after TKA between conventional and CAS procedure.

Objective: The purpose of the present study was to report the results of radiographic comparisons made between CAS-TKA and conventional TKA.

Material And Method: The authors retrospectively compared 102 knee radiographs from conventional TKA to 84 knees from CAS-TKA.

Results: The mean mechanical axis deviation was 2.
