“…All patients had consecutive MRI scans of their operated knee and comparison scans of their bilateral knees and thighs, at least in two different periods post‐operatively. Our results show lower or similar incidence of medial hamstrings regeneration compared to other studies [2, 9–14, 19, 21, 25, 29, 31, 33, 35]. The gracilis tendon demonstrated a smaller number of “complete” regenerations (36 %) compared to the semitendinosus tendon (64 %).…”

Background: The treatment of anterior glenohumeral instability with a Bankart repair combined with a capsular plication is a frequently used arthroscopic technique. Latarjet created an open bone block procedure in 1954 for the treatment of anteroinferior glenohumeral instability. This procedure has been further developed by Lafosse in 2003 for arthroscopic surgery. The aim of this study is to evaluate the clinical outcome and complications of the latter procedure, most notably infection rate and nerve damage. Materials and Methods: 132 shoulders (106 males/19 females, 68 right/64 left) were included in this retrospective study. Patients were included if treatment was performed for anterior instability and if the patient's instability severity index score was at least 4, or if a revision procedure was performed after a prior unsuccessful arthroscopic or open capsule and labral repair. Treatment included the arthroscopic transfer of the coracoid process for the anterior stabilization of the shoulder joint. The disabilities of the arm, shoulder, and hand score were evaluated postoperatively in 76 patients and compared with the results found in the literature. Mean followup was 20.1 [±14.09] months. Results: The rate of recurrent glenohumeral instability which needed revision surgery after the arthroscopic Latarjet procedure was 6.1% ( n = 8). There were no severe neurovascular complications seen in our cohort. In 32 cases, re-operation was performed due to subjective discomfort because of screw impingement or postoperative shoulder stiffness. Conclusion: The all-arthroscopic Latarjet procedure developed by Lafosse is a valid and reliable method for the treatment of shoulder instability. Our favorable results indicating that this procedure can prevent chronic shoulder luxation are repeatable, and the rate of postoperative recurrence is low.

ObjectivesThe objective of this study was to determine if the use of fascia lata as a tendon regeneration guide (placed into the tendon canal following harvesting the semitendinosus tendon) would improve the incidence of tissue regeneration and prevent fatty degeneration of the semitendinosus muscle.Materials and MethodsBilateral semitendinosus tendons were harvested from rabbits using a tendon stripper. On the inducing graft (IG) side, the tendon canal and semitendinosus tibial attachment site were connected by the fascia lata, which was harvested at the same width as the semitendinosus tendon. On the control side, no special procedures were performed. Two groups of six rabbits were killed at post-operative weeks 4 and 8, respectively. In addition, three healthy rabbits were killed to obtain normal tissue. We evaluated the incidence of tendon tissue regeneration, cross-sectional area of the regenerated tendon tissue and proportion of fatty tissue in the semitendinosus muscle.ResultsAt post-operative week 8, the distal end of the regenerated tissue reached the vicinity of the tibial insertion on the control side in two of six specimens. On the IG side, the regenerated tissue maintained continuity with the tibial insertion in all specimens. The cross-sectional area of the IG side was significantly greater than that of the control side. The proportion of fatty tissue in the semitendinosus muscle on the IG side was comparable with that of the control side, but was significantly greater than that of the normal muscle.ConclusionsTendon tissue regenerated with the fascia lata graft was thicker than naturally occurring regenerated tissue. However, the proportion of fatty tissue in the semitendinosus muscle was greater than that of normal muscle.Cite this article: K. Tabuchi, T. Soejima, H. Murakami, K. Noguchi, N. Shiba, K. Nagata.

Semitendinosus Regrowth

Abstract: Hamstring tendon regrowth may have a dramatic impact on postoperative function of patients who undergo anterior cruciate ligament reconstruction with these tendons. Further modulation of this regeneration may further reduce graft harvesting morbidity.
