The elbow joint is critical for positioning the hand to carry out activities of daily living. Deficits in elbow joint range of motion, torque production capabilities, or alterations in elbow joint stiffness affect the ability to successfully carry out feeding, grooming, and other essential activities [1]. Thus quantifying elbow joint stiffness is desirable. Quantifying elbow joint stiffness could help diagnose, monitor and rehabilitate elbow impairments if its relationship to them is known. Ultimately, accurate measurements of joint stiffness can also impact the design of artificial limbs and human motor system control and simulation. The long-term research goal is to quantify how elbow stiffness changes with elbow joint flexion angles, movement speeds, muscle contraction, and injury or disease. The immediate goal was to validate that a recently-modified Stiffness Tester measures elbow stiffness values within the range of those previously reported. The expectation was that muscle contraction level and joint position would influence the elbow stiffness values.

Joint Limitation

Joint stiffness, resulting from a variety of complications after hand injuries, remains a common problem. Prolonged swelling, scar formation and shortening of soft tissue after prolonged period of immobilisation are the major causes leading to the loss of joint range of motion. Treatment used to improve the joint stiffness should be integrative and problem-focused. Pressure therapy, active and passive mobilisation through remedial activities and corrective splinting should be started as soon as problems arise. Applying low-load stress through prolonged periods of time onto the shortened tissue at its maximum tolerable range is the main principle in restoration of passive joint range of motion. The greater the joint limitation becomes, the longer the time the splint should be applied. Therapists should understand the process of tissue healing and different functions of splints before a correct and effective splint can be prescribed properly.

Complex Anatomy

Loss of elbow motion can lead to disability in everyday gestures, recreational activities, and work. Unfortunately, the elbow joint is particularly prone to stiffness because of its complex anatomy and biomechanics. The etiology of elbow stiffness is varied and must be diagnosed accurately in order to allow optimal treatment, which may be challenging for surgeons and physiotherapists. Its treatment can be either conservative, arthroscopic or surgical, with a trend for arthroscopic procedures when conservative treatment fails. There is no consensus on the optimal imaging workup for elbow joint stiffness, which may have an impact on patient management. This article reviews the current classification systems of elbow stiffness and the various imaging techniques used for diagnosis. Report checklists and clarifications on the role of each imaging method, as well as the imaging findings of normal and stiff elbows, are presented, leading to a proposed diagnostic algorithm. The main concern in imaging is to determine the cause of elbow stiffness, as many concomitant abnormalities might be present depending on the clinical scenario.

The role of arthroscopy in incipient and mild arthrosis, even combined with proximal tibial ostetomy, is well known and well documented. On the other hand, its role in the treatment of advanced arthrosis of the large joints, especially the knee, is a subject of controversy. The proponents of the use of arthroscopy in advanced arthrosis claim that meniscectomy, synovectomy, ostophytectomy, chondral lesion stabilization, arthroscopic release, plica and loose body removal greatly improve the quality of life for most patients, especially if followed by the use of viscoelastic injection, by diminishing pain and improving joint range of motion. The opponents claim that, even though the advantages are clear in the cases that refuse arthroplasty, in all the other cases the surgical indication should be total knee arthroplasty, as the clinical relief is temporary, but with all the risks of a surgical intervention. We have conducted an overview of the recent literature, in order to find objective evidence to sustain either point of view. We focused on articles published that included an objective measurement of before and after clinical status through clinical scores and objective measurements. We also focused on the follow-up period and on the evolution of the pathology after arthroscopy.
