Primary tendon healing: A review

https://doi.org/10.1016/S0363-5023(77)80023-3Get rights and content

Clinical and experimental studies on primary tendon healing are reviewed and correlated. Emphasis is placed on the importance of blending the extratendinous and intratendinous elements of tendon healing to obtain optimal functional results. Studies which demonstrate the ability of tendon cells to metabolize, proliferate, and secrete collagen when isolated from paratendinous tissue are cited along with those which demonstrate the importance of the microcirculation of the tendon in tendon healing. Those factors which interfere with intratendinous healing are discussed, such as invasive suture techniques, tension on the area of repair, and interference with segmental blood supply within zone II. The importance of the synovial sheath and synovial fluid in nourishing tendon cells and the effect of ischemia in stimulating the ingrowth of adhesions are brought out. Discussion includes such factors involved in the postoperative management of tendon repairs as those which affect the strength of tendon repairs and quantitative and qualitative methods of modifying adhesion formation.

      Although different anti-adhesion strategies including nonsteroidal anti-inflammatory drugs (NSAIDs) and adhesion barriers are used to reduce the risk of adhesion formation during the tendon healing process, the prevention of surgical adhesions is still a main challenge for orthopedic surgeons [5–7]. In tendon healing procedures, large amounts of immune/inflammatory cells and fibroblasts are recruited to the site of injury [8]. Fibroblasts have a significant role in tendon repair via secretion of various collagen types, restoring the continuity of collagen fibers in the tendon structure.

      However, the real efficiency of sutures performed using this fixing method is still questioned, in comparison with the traditional techniques.1,3,16 For a long time, the idea that tendon reinsertion should be made as resistant as possible by multiple sutures has been advocated, with the tendon fixed using trans-osseous stitches in a spongy bone bed4,6,21; however, multiple stitches may reduce the microcirculation of the tendon and impair healing.8 Some authors have attempted to demonstrate which type of repair is better (ie, in the spongy bone bed [for trans-osseous suture] or in the cortical bone bed [for suture using anchors]), by investigating whether these types of repair have different biomechanical properties over the course of the phases of healing.
