Aim. Over the last 15 years there has been a series of publications reporting the beneficial effects of elbow arthrolysis, with considerable variation in operative technique and post-operative management. Many advocate the use of passive stretching techniques in the early post-operative period if range of motion fails to improve satisfactorily. The purpose of this study was to assess our results of open elbow arthrolysis in patients who did not receive any passive stretching after discharge from hospital. Methods. Prospectively collected data of 55 patients with a minimum follow-up of 1 year after arthrolysis were analysed. All procedures were performed by the same surgeon (LR), achieving as much improvement in elbow motion as possible at operation. All patients had continuous brachial plexus blocks and continual passive motion for 2-3 days post-operatively but none received any passive stretching after discharge. At review, a senior physiotherapist (BD) formally assessed all the patients. Results. All patients' arc of movement improved from 68 degrees to 104 degrees (flexion 18 degrees/extension 23 degrees). Upper limb function (Disabilities of the Arm, Shoulder and Hand score) improved by 50%. Pain decreased from 20 to 9, measured with a Visual Analogue Score. The greatest improvement in motion was obtained in the stiffest elbows - 7 patients with an arc of 30 degrees or less pre-operatively achieved an arc of 100 degrees by the time of the last review. Conclusions. Good results of open arthrolysis for post-traumatic elbow stiffness can be achieved with continuous brachial plexus blocks and continual passive motion for 2-3 days post-operatively. There appears to be little evidence to support treatment with passive stretching techniques after discharge from hospital, as our results are similar to other reported series

Stiffness after TKR is a frustrating complication that has many possible causes. Though the definition of stiffness has changed over the years, most would agree that flexion > 75 degrees and a 15-degree lack of extension constitutes stiffness. This presentation will focus upon the potential causes of a stiff TKR, intra-operative tips, the post-operative evaluation and management, and the results of revision for a stiff TKR. The management of this potentially unsatisfying situation begins pre-operatively with guidance of the patient's expectations; it is well-known that pre-operative stiffness is strongly correlated with post-operative lack of motion. At the time of surgery, osteophytes must be removed and the components properly sised and aligned and rotated. Soft-tissue balancing must be attained in both the flexion/extension and varus/valgus planes. One must avoid overstuffing the tibio-femoral and/or patello-femoral compartments with an inadequate bone resection. Despite these surgical measures and adequate pain control and rehabilitation, certain patients will continue to frustrate our best efforts. These patients likely have a biological predisposition for formation of scar tissue. Other potential causes for the stiff TKR include complex regional pain syndrome or joint infection. Close followup of a patient's progress is crucial for the success in return of ROM. Should motion plateau early in the recovery phase, the patient should be evaluated for manipulation under anesthesia. At our institution, most manipulations are performed within 3 months post-operative under an epidural anesthetic; patients will stay overnight for continuous epidural pain relief and immediate aggressive PT. The results of re-operations for a stiff TKR are variable due to the multiple etiologies. A clear cause of stiffness such as component malposition, malrotation or overstuffing of the joint has a greater chance of regaining motion than arthrofibrosis without a clear cause. Although surgical treatment with open arthrolysis, isolated component or complete revision can be used to improve TKR motion, results have been variable and additional procedures are often necessary
