Patient Satisfaction Following Total Knee Arthroplasty: Comparison of Short-Term Results in Rheumatoid Arthritis and Osteoarthritis.

Arch Bone Jt Surg 2019 Jan;7(1):61-66

Background: Due to the obvious differences in the natural course of rheumatoid arthritis (RA) and osteoarthritis (OA), different functional outcomes might be expected after Total Knee Arthroplasty (TKA) in these distinct patients. Although several studies have reported the objective outcome of TKA in RA and OA patients, few studies have compared post-operative patient-satisfaction levels.

Methods: In this clinical cohort study 171 patients (RA: n=33, OA: n=138) who underwent TKA with posterior stabilizing knee prosthesis were included. The Knee Injury and Osteoarthritis Outcome Score (KOOS) and Oxford Knee Score (OKS) were used to evaluate and compare patients' satisfaction 6 and 12 months after TKA relative to their preoperative state and to make an assessment between two groups.

Results: Both of patient-reported scoring systems showed a statistically significant improvement for OA and RA patients at 6 and 12 months after surgery, relative to their preoperative scores. The results of the OKS and KOOS did not show statistically significant improvement from 6 to 12 months n RA patients. Unlike RA group, OKS and KOOS revealed further improvement between 6 and 12 months for the osteoarthritic patients.

Conclusion: OA patients had continuous improvement in their satisfaction in the first year after TKA with a gentle upward curve. In contrast, in RA patients, recovery was faster and greater in the first six months after surgery and slowed down in the second six months. Patient-reported outcome scores were not significantly different between two groups at the end of the first year.

Revision anterior cruciate ligament (ACL) reconstruction is a technically demanding enterprise. Management of widened or previously malpositioned tunnels is challenging and often requires innovative approaches. The purpose of this study was to evaluate the function and clinical results of revision single-stage ACL surgery using an anterolateral tibial tunnel (ALTT). A consecutive series of knees with arthroscopic ACL revision surgery were analyzed prospectively between April 2012 and September 2015. Among the 93 patients presented with revision ACL reconstruction, 25 patients met the study inclusion criteria for the ALTT technique and were followed up for a minimum of 2 years (range: 24-51 months). The clinical results were evaluated by means of the Lysholm score, International Knee Documentation Committee (IKDC) score, and Tegner activity level scale, and the knee stability was assessed by the Lachman test, pivot shift test, and anterior drawer test. Magnetic resonance imaging (MRI) of the index knee before the surgery and 2 years after revision surgery was assessed. The mean IKDC subjective score, mean Tegner activity level scale, and mean Lysholm score significantly improved in all study participants. This study showed that ACL revision surgery with ALTT can reliably restore stability and provide fair functional outcomes in patients with ACL retear. One could expect acceptable lateral tibial tunnel length compared with medial tibial tunnel in classic ACL revision, intact bony surround, and good graft fixation. This technique is clinically relevant in that making an anterolateral tunnel in one-stage ACL revision surgery had a good subjective result with low complication rate in midterm follow-up.
