Background

Readmission following any total joint arthroplasty has become a closely watched metric for many hospitals in the United States because financial penalties imposed by CMS for excessive readmissions occurring within thirty days of discharge has occurred since 2015. The purpose of this study was to identify both preoperative comorbidities associated with and postoperative reasons for readmission within thirty days following primary total joint arthroplasty in the lower extremity.

Background

Readmission following any total joint arthroplasty has become a closely watched metric for many hospitals in the United States because financial penalties imposed by CMS for excessive readmissions occurring within thirty days of discharge will be forthcoming in 2015. The purpose of this study was to identify both preoperative comorbidities associated with and postoperative reasons for readmission within thirty days following primary total joint arthroplasty in the lower extremity.

Purpose: The purpose of this randomised controlled trial was to compare outcomes of operative and non-operative management of Achilles tendon ruptures.

Method: Patients with acute complete Achilles tendon ruptures were randomised to receive open suture repair followed by graduated rehabilitation or graduated rehabilitation alone. The primary outcome measure was re-rupture rate. Assessments at three and six months, and one and two years included a modified Leppelhati score (no strength data), range of motion, calf circumference, and isokinetic strength at one and two years. We report the two year findings.

Results: Two centres randomized 145 patients (118 males and 27 females), mean age 40.9±8.8 years (22.5 – 67.2) to operative (n=73) and non-operative (n=72) treatment. Fourteen were lost to follow-up. Re-rupture occurred in three patients in both groups. The mean modified Lep-pelhati score (out of 85) was 78.2±7.7 in the operative group and 79.7±7.0 in the non-operative group, which was not significant (−1.5 95%CI −6.4 to 3.5, p=0.55). Mean side-to-side difference in plantar flexion and calf-circumference in the operative group was −2.0±3.2° and −1.4±1.2cm, and in the non-operative group −0.9±3.0°and −1.6±1.8cm respectively. Mean isokinetic plantar flexion strength was 62.4±24.2 for the operative and 56.7±19.3 for the non-operative group, which was not significant (5.7, 95%CI −3.1 to 14.5, p=0.20). There were a greater number of serious adverse events in the operative group, including pulmonary embolus in one patient, deep vein thrombosis in one and deep infections requiring irrigation and debridement in three.

Conclusion: This study suggests that non-operative management of Achilles tendon ruptures utilizing an accelerated rehabilitation programme may produce comparable results with fewer adverse events.
