Tendon surgery

I was doing some research on tendon surgery today and came across this, which is a good description of the surgery I'll be having on the 14th:

"Surgery should include diagnostic arthroscopy to exclude any intra-articular pathology. If arthroscopy reveals no intra-articular derangement, then an incision is made directly over the direct head insertion of the semimebranosus tendon. The semimembranosus tendon is dissected free from surrounding tissue and the sheath is opened. Any areas of necrosis or degenerative tissue should be excised. Several longitudinal tenotomies are performed. In addition, the insertion site is drilled with a small Kirschner wire to promote a healing vascular response. Tendon rerouting or suturing the semimembranosus to the posterior aspect of the medial collateral ligament has also been proposed if friction between the tendon and the tibial plateau exists. In one report, the results of surgery were good in 9 of 10 patients, and allowed return to sporting activities at an average of 12 months postoperatively."
