Phase4 (12~16weeks)

Phase3 (8~12weeks)

⇒ Remodeling repair tissue does not reach maximal tensile strength for a minimum of 12~16 weeks post repair

* Dynamic activity(after 10wks)

* AROM activity

* Avoid ER/IR band exe(only large & massive tear: at least 16wks)

Isotonic periscapular & CKC exercise

Phase1 (1~4weeks)

⇒ Avoided end range stretch (first 6 weeks), active exe

● Avoided pulley exe

● Avoided elevation from 30 to 60° (more 2 tendon injury, subscapularis injury)

Phase1 (1~4weeks)

▣ collagen deposition and growth factors increase, with a peak increase around 10 days after surgery

▣ repair should not be exposed to the excessive forces inposed by active motion

▣ Pressure at the end range (stretching) should be avoided for the first 6 weeks

▣ PROM is progressed with caution

□ Started periscapular activation

- isolated scapular depression, retraction performed and has shown to exhibit minimal posterior RC cuff activity

□ Approximately 20~30° of scapular plane

- preventing decreased blood flow in the supraspinatus

- increasing the subacromial space

회전근개에 문제가 생겨 재봉합하는 수술

재활의 목적 > 통증완화와 가동범위 회복, 기능 회복

합병증 보통 1.5% ~ 2.7%로 환자들의 어깨 움직임시 뻣뻣함 호소 > 치료시 신경써야한다.

재활가이드라인

회복 초기는 조직의 회복과 염증 통증감소 수술부위의 보호가 가장 중요.

수술 직후 4~6 주까지는 팔을 고정해주는 것이 중요하며 수술 후 어깨의 뻣뻣함 줄이기 위해 적절한 ROM운동이 필요하다.

회복과정은 3가지 단계로 구분

1 염증기 2 회복기 3재형성기

Operative treatment

Retear time rate

□ 22 patients with large or massive tears (>3cm)

- immobilization 4 week, strengthening 12 weeks

□ 66% retears, occurred within 3 months

□ 33% tetears, occurred after 6 months

□ No retears from 6 to 24 months

ROM gains

□ Type 1 : small tears (1cm, very good tissue quality)

- Full AROM 6~8 weeks

□ Type 2 : large tears ( <3~5cm, adequate tissue)

- Full AROM 8~12 weeks

□ Type 3 : large massive tears ( 3~5cm<, poor tissue, retracted tissue)

- Full AROM 12~16 weeks

Rotator cuff tensile strength

□ Ablilty to tolerate up to 100 N/mm of tensile strength

□ However, the tendons' endurance of compressive and shear forces is much less

□ Irritation and inflammation of the subacromial bursa which is rich in nerve fibers

Bursa

□ protection from shearing forces

□ contribute to the blood supply

□ healing of the rotator cuff particularly

□ preservation of the tissue

□ Bursectomy

- lead to rotator cuff tears or adhesions of the tendons of capsule

Tendon Healing Potential

□ Partial -thickness, small full thickness tears of the rotator cuff may heal spontaneously.

□ Most small tears will enlarge if not surgically repaired

Rotator cuff healing stage

염증기 > 증식기 > 재형성기

염증기

* Following surgical tendon-to-bone fixation

* Occurs first 7 days

* The release of histamine and bradykinin increases vascular permeability

* Inflammatory cells followed by platelets and fibroblasts migrate into the repair site

* Cellular proliferation and matrix deposition of this phase is thought to be regulated by several growth factors and initially yields primarily type 3 collagen.

증식기

* When next 2~3 weeks, begin to proliferate or repair

* This tissue replaces, which occurs 2 to 3 weeks after tendon ingury or repair

* Combine with capillary buds and nascent extracellular matrix to form granulation tissue.

재형성기

* During the following week(after 4weeks), this repair tissue grows stronger during the transition to the maturation phase.

* Scar tissue organizes through extracellular matrix turnover.

* The initial type 3 collagen deposition is slowly replaced by type 1

collagen, continuing until mature scar tissue is formed

* Remodeling repair tissue does not reach maximal tensile strength for a minimum of 12~16 weeks post repair, returned to maximal failure loads after only 26 weeks of healing.

Fisk factors of stiff shoulder after cuff repair

□ Calcific tendinitis

□ Adhesive capsulitis

□ PASTA type repair

□ Concomitant SLAP repair

□ Single tendon repair

Effect of immobilization

□ Postoperative immobilization can minimize the tension on rotator cuff repairs and may lead to improved collagen orientation and visco-elastic properties as compared to immediate postoperative exercise treatment

□ Immobilization of the shoulder for 4-6 weeks in a slightly abducted position may minimize tension and maximize vascularization of the repair

신장분사 치료

□ post-surgically to decrease pain, swelling, muscle spasm, and minimize the inflammatory response

□ authors recommend the use of a home cryotherapy device for 10-14 days after surgery

관절 가동술

□ 30도 abduction in the scapular plane

- anterior and posterior translational glides do not significantly alter stress on repaired supraspinatus tendons with the arm in resting position.

□ Especially, posterior translational glides have shown to significantly increase external rotation range of motion in patients with stiff shoulders.

□ Progressed ROM to 4-6 weeks after surgery

정적요소

only 25~30% of the humeral head is in contact with the glenoid fossa.

Dynamic factors

●Rotator cuff

▷increase joint stability

▷increase joint compression

▷steering

▶ Exernal rotation is important for clearance of the greater tuberosity during elevation

Effect of external rotation during elevation

▷increase humeral external rotation at scapular plane than sagittal and coronal plane.

▷Exernal rotation

its associated tissues as it passes under the coracoacromial arch

Effect of humeral ER

GH Joint Kinematics

● Subscapularis teres minor, infraspinatus contribute to depression of the humeral in the glenoid cavity more than does the supraspinatus. And/or provides dynamic stability to the GH joint during deltoid activation.

Subacromial space

● Height of the subaromial space

▷ 1~1.5cm

● At 90 elevation(healthy)

▷ 4.1mm

● Shoulder impingement

▷ 1.4mm

⇒ 6mm Superior displacement of humeral head if rotator cuff tear space effect
