Om icke operativ behandling beslutas skall patienten överväga att modifiera sin aktivitetsnivå. Undvika snabba stopp och vridningar

Reflex Inhibition Smärta och svullnad medför inhibition av voluntär muskelaktivitet. Mål: Minska smärta och svullnad.

Tidig rörelseträning? Animal studies have shown that physical training affects the characteristics of ligaments Tensile Strength Elastic Stiffness Total weight of ligamentous tissue Message: Improved biomechanical properties of the ligament-bone junction by exercise Tipton 1984

Motion studies: Human subjects (Woo, et al 1982) Answer: In principle, motion should start as early as possible, as it improves both the structural and mechanical properties

Should early motion be allowed in ACL reconstructed patients? T. Häggmark and E. Eriksson (1978 ): Early motion is possible and even beneficial after ACL surgery Answer: Yes

ACL Rehabilitation What motions are safe to carry out post-operatively without compromising ACL graft integrity and healing?

ACL strain pattern during open kinetic chain - active flexion-extension

Closed kinetic chain exercise - Squatting with and without Sport Cord

ACL Rehabilitation Study at our department showed that doing only functional exercises during ACL rehabilitation can lead to muscular weakness i.e. not regaining full strength. Conclusion: CKC should be combined with OKC (Mikkelsen, Werner ESSKA Journal 2001)

Rehabilitation Exercise Peak Strain Isometric quads contraction @ 15 o (30 Nm) 4.4 (0.6)% 8 Squatting w/ Sport Cord 4.0 (1.7)% 8 Active flexion-extension w/ 45 N weight boot 3.8 (0.5)% 9 Lachman test (150 N; 30 o flexion) 3.7 (0.8)% 10 Squatting 3.6 (1.3)% 8 Active flexion-extension of the knee (no weight boot) 2.8 (0.8)% 18 Simultaneous quads and hams contraction @ 15 o 2.8 (0.9)% 8 Isometric quads contraction @ 30 o (30 Nm) 2.7 (0.5)% 18 Anterior drawer (150 N; 90 o flexion) 1.8 (0.9)% 10 Stationary Bicycling 1.7 (1.9)% 8 Isometric hams contraction (-10 Nm; 15 o flexion) 0.6 (0.9)% 8 Quads and hams co-contraction (30 o flexion) 0.4 (0.5)% 8 Passive flexion-extension of the knee 0.1 (0.9)% 10 Isometric quads contraction (30 Nm; 60 o flexion) 0.0% 8 Isometric quads contraction (30 Nm; 90 o flexion) 0.0% 18 Quads and hams co-contraction (60 o flexion) 0.0% 8 Quads and hams co-contraction (90 o flexion) 0.0% 8 Isometric hams contraction (-10 Nm; 30 o, 60 o & 90 o ) 0.0% 8 n

The use of FKB- a summary Biomechanics: FKB have some stabilizing effect on the knee during lower loads Proprioception: Some enhancing effects Clinical: --FKB are not needed after ACL surgery --FKB seem to be beneficial for ACL deficiency Conclusion: There is a role for FKB in the management of knee instability

Aggressive rehabilitation after ACL surgery - Any risks? Human Studies Aggressive early rehabilitation after surgery using the hamstring tendons had increased risk of residual laxity compared to the B-PT-B. (Muneta et al, Journ. Orthop. 22, 1998) Aggressive rehabilitation resulted in increased laxity and swelling after three months as compared to conventional rehabilitation. (Johnson, Beynnon, Renström et al. 1999)

Take home message Effects of inactivity and immobiliztion are devastating for recovery Early motion and loading are important for recovery of the musculo- skeletal tissues after injury A well designed goal-oriented program is the only way for a speedy and safe recovery after injury

Take home message ACL injuries are still the greatest problem in Orthopedic Sports Medicine!! Surgery of knee ligaments injuries is not only surgery--rehabilitation is as important!! ACL reconstruction will not restore the knee to normal!! Management of knee injuries is a team work!! Many questions remain to study to get answers!!

Final words: We must know what we are doing Our actions must be based on science combined with long term experience More Science is needed!

Senskador Tendinopathy is the combination of tendon pain, swelling and impaired performancce indicates the clinical diagnosis tendinopahy Paavola et al 2002, Maffuli et al 2002

Ålderns betydelse 8-18 years Muscle-tendon junction problems 18-55 years Increasing incidence after 30-35 years 55 år Decrease in ultimate strain and load, tensile strength, and an increase in stiffness (Banks et al 1999). The rate of degeneration with a age can be reduced by regular activity (Jozsa, Kannus 1997) Shoulder injury increasingly common with age --18%

Riskfaktorer extrinsic factors: - felaktig träning - underlag intrinsic factors: - malalignments - muskelsvaghet -ålder Kom ihåg! Ont om bra studier

Extrinsic factors It is clinically accepted that a change in load, training errors (linked to a change in load), changes in the environment, and change or faults with equipment can result in onset in tendon symptoms (Kannus, 1997). Other extrinsic factors have little evidence to support them and further research is required.

Proven intrinsic factors Do they need biomechanical corrections?? Intrinsic factors associated with Achilles tendinopathy are Malalignment of lower leg in 60% of Achilles disorders Increased forefoot pronation ( Nigg 2001) Increased hindfoot inversion, decreased dorsiflexion with the knee in extension and varus deformity of the forefoot (Kaufmann et al.2000) Limited mobility of the subtalar joint and rom of the ankle (Kvist 1991) Conclusion: Biomechanical abnormalities should be corrected but may not be important (Åström 1997)

Pathology?? Is inflammation present? No or minimal (3-5%) inflammation Arner 1959, Puddu 1976 Alfredson et al 2000, Zamora & Marini, 1988 But it is important to note that the absence of inflammatory modulators at end stage disease does not mean that they are not present in early stage disease Tendinosis is degenerative process of tendons, seen as hyaline and mucoid degeneration, lipomatous infiltration of tendon, fibrillation of collagen fibres Puddu et al 1976

What should these overuse tendon conditions be called? Conclusion: Tendinits is wrongly usually used for chronic tendons conditions that in reality are tendinosis This leads the athletes to underestimate the proven chronicity of the problem Maffuli, Kahn, Puddu 1998 Suggestion: Let us call these chronic painful degenerative tendon conditions for tendinopathy

Behandling Successivt ökad ffa excentrisk träning Sklerosering av blodkärl ESWL Akupunktur Kortison??? undvik! Sjukgymnastik Om konservativ behandling misslyckas får man överväga operation

Excentrisk träning Hypotes: Stärker senor genom stimulering av mekanoreceptorer i tenocyter som i sin tur producerar kollagen

Excentrisk träning The idea of eccentric exercise in treating tendinopathy was introduced by Curwin and Stanish in 1984 In a prospective randomized study on Achilles chronic tendinopathy verified by ultrasound eccentric training was shown to be effective (Alfredson et al 2001, 2003)

Effects of exercise Relative changes from rest to exercise Tendon Muscle Blood flow 3-7 fold 10-20 fold Oxygen uptake 3-6 fold 20-30 fold Glucose uptake 2-3 fold 5-15 fold

Acupuncture- effective? Effective through Analgesia Improvement of circulation Immunological response (KM Chan 2003)

Extracorporal Shock Wave Therapy (ESWT) Longitudinal studies: great --ESWT is reported effective (Rompe 1996,Ogden 2001). Comparative study (CJSM): good --It shows comparable outcome to surgery of patellar tendinopathy (Peers et al 2003) Could be indicated in insertional tendinopathy after other consevative treatment failed Be aware: More research is needed!!

Sclerosing therapy Material Mid-portion n=58 elite athletes n=11 injections:n=146 Distal n=18 elite athletes n=4 injections n=56 Results promising but there is reason for caution Alfredson et al Knee Surg, Sports Traumatol, Arthrosc, 2003

Surgery some background Remember: An incision gives a strong healing response Surgical technique is probably not very important. Observations: We do not know the physiological and biological bases for the effect of surgery. The relationship operative treatment and healing is not well understood (Jozsa, Kannus 1997).

Surgical management of Achilles and patellar tendinopathies There are no validated surgical protocols Technique: Needling, Coblation, Percutaneous (ultrasound guided) tenotomy, Percutaneous paratenon stripping, Open tenotomy and paratenon stripping, Tendon grafting Arthroscopic debridement (tendoscopy) is slowly taking over Surgery is not difficult technically but experience is need to decide what to do.

Return to sports after surgery for tendinopathy may take long time!!!! Rule of thumb for return to sport: When there is no increase of symptom Chronic injury may require 4-6 months for Achilles tendinopathy 6-12 months for patellar tendinopathy 8-14 months for rotator cuff
