Pre and Post-Operative Physiotherapy in Knee Arthroscopy Surgeries




Knee arthroscopy from a physios perspective
¢  Young patient
¢  Active lifestyle
¢  Traumatic injury
¢  Athlete
¢  Functional Goal Setting: Patient may need to attain functional independence in BADL’s and also in relation to work demands and rarely to attain the sports activities being played.

Indications for Arthroscopic Repair/ Reconstruction:
¢  Injured ligament (different healing capabilities)
¢  Location & size of lesion
¢  Degree of instability experienced by patient
¢  Other associated injury – meniscal tear, articular damage etc
¢  Patients desired level of function
¢  Risk of re-injury
¢  Prevention of future impairment

Arthroscopy – Physiotherapist’s consideration
Indication for ligament surgery –
            Failed conservative management, early degenerative changes seen, pain/ loss of function.
Type of ligament surgery:
            Intra articular, extra articular, combined procedures
Grafts used:
            Autograft, allograft, synthetic, area of harvesting etc.

Pre-operative physiotherapy
¢  Deficits in pre-operative quadriceps strength influence function 6 months after ACL reconstruction
            David Logerstedt et al, The Knee, 2013

Pre-operative management & goals
‘Injuries around the Knee’ Symposium: Sancheti Parag et al, Br J Sports Med, 2010
¢  Oedema Control
¢  Minimize muscular atrophy
¢  Maintain ROM as much possible
¢  Protected ambulation
¢  Patient education
¢  Restoration of joint stability & motion
¢  Pain free & stable weight bearing
¢  Sufficient post-operative strength & endurance to meet functional demands
¢  Ability to return to pre injury activities
           
Post-operative management
  1. Maximum protection phase  – Weeks 1 – 4
  2. Moderate protection phase – Weeks 4 – 8
  3. Minimum Protection phase – Weeks 8 & beyond

Maximum protection phase – weeks 1 – 4
            TREATMENT GOALS:
¢  Protect healing tissues
¢  Prevent reflex inhibition of muscles
¢  Reduce joint effusion
¢  ROM 0 – 110°
¢  Active control of ROM
¢  Weight bearing 75% to tolerance (depends on specificity of tissue repaired)
¢  Early controlled weight bearing does not compromise knee joint stability and provides a better outcome in terms of VMO function
            Tyler TF Clin Orthop Relat Res, 1998

Intervention
Early: Days 1 – 14

¢  RICE
¢  Gait training – crutches PWB
¢  Passive to active ROM (with range limiting braces if required)
¢  Using CPM for ROM does not offer any additional benefits
Rosen MA Am J Sports Med, 1992
¢  Patellar mobilization
¢  Muscle setting exercises – Quads, hams, adductors at multiple angles
¢  Assisted SLR in supine (with brace when needed)
¢  Ankle pumps


Late: weeks 2 – 4
¢  Continue previous exercises
¢  Full weight bearing & closed chain exercises for hip & knee muscles (with permission)
            (Not in meniscal injuries)
¢  Low resistance PRE in open chain activities
¢  Core stabilisation exercises
¢  Aerobic conditioning – static cycles
¢  Physiotherapy is equally effective as arthroscopic partial menisectomy for meniscal tears and OA knees
            Katz et al. Engl J Med. 2013
¢  In a RCT, home exercise program alone was better versus arthroscopy in addition to home exercise program for chronic patello-femoral pain syndrome
            Kettunen et al Br J Sports Med. 2012
¢  Post-operative physical therapy accelerated rehab in arthroscopic partial menisectomy: Systemic Review with Metanalysis
            Dias et al J Orthop Sports Phys Ther 2013
¢  Electromyographic feedback along with conventional exercise therapy speeds up the rehab process
            Akkaya N et al Clin Rehabil. 2012
      
     
BRACING
¢  Using a functional brace or a neoprene sleeve post arthroscopic repair helps in improving joint position sense in early rehab phase
            Beynnon BD, J Orthop Sports Phys Ther, 2002;
                Brandson S et al Scand J Med Sci Sports, 2001

Moderate protection phase weeks 4 – 10
TREATMENT GOALS:
¢  Full pain free ROM
¢  Strength Gr. 4/5
¢  Dynamic joint (knee) control
¢  Improved kinaesthetic awareness
¢  Normalise gait pattern & ADL function
¢  Home exercises program

Intervention
            Early – weeks 5 – 6:
¢  Multiple angle isometrics
¢  Advanced closed chain strengthening & PRE
¢  Stretching exercises
¢  Endurance training
¢  Proprioceptive training – single leg, tilt board
¢  Stabilization exercises with elastic bands


Proprioceptive training and core strengthening
¢  Both form important aspects of phase 2 rehabilitation.
            Lephart SM Am J Sports Med, 1997
¢  Lack of core strengthening and proprioceptive training post arthroscopic cruciate reconstruction have been found to be associated with reduced stability and performance in patients
            Cinar-Medeni O, Am J Phys Med Rehabil, 2014

Intervention
            Late – weeks 7 – 10:
¢  Continue with previous exercises
¢  Advance strengthening (PNF patterns)
¢  Endurance & flexibility training
¢  Advanced proprioceptive training
¢  Walking/ jogging
¢  Initiate plyometric training (with permission in athletes)



Minimum protection phase weeks 11 - 24:
TREATMENT GOALS:
¢  Increase strength, power & endurance
¢  Improve neuromuscular control, dynamic stability & balance
¢  Improve cardio pulmonary fitness

Joint stability achieved by neuro musculoskeletal system


Intervention
¢  Continue stretching program
¢  Advanced PRE. Initiate isokinetic training if desired.
¢  Advanced close chain exercises & plyometric drills.
¢  Advanced proprioceptive training.
¢  Progressive agility drills (fig of 8, specific drills)
¢  Progress running program



Return to activity phase – 6 months & beyond
TREATMENT GOALS:
¢  Increase strength, power & endurance
¢  Regain ability to function at highest desired level
¢  Maintenance program
¢  Reduce risk of re-injury

Balance and Proprioceptive Training

Plyometric Training (Sports Specific)


Intervention
¢  Progress PRE & flexibility exercises
¢  Advanced agility drills
¢  Sports or occupation specific drills
¢  Need of protective bracing prior to return to work or sports.



Current trends in rehabilitation
¢  Shift towards individually tailored/ modified programs depending on functional requirement of the individual
¢  Functional training programs – exercises similar to ADL’s of the individual
¢  Limited Use of CPM machines
¢  Cryotherapy pre-op/ post-op beneficial to control pain and swelling
¢  Functional Testing to assess joint stability
¢  Emphasis on Proprioceptive Training
¢  Patient Perceived joint stability most important criteria for Prognosis
¢  Time not a major factor in determining treatment progression
¢  ROM, muscle strength and patient perceived joint stability most important criteria for exercise progression
¢  Delayed Surgery – faster strength recovery
            Wasilewski  et al 1993 , Shelbourne and Foulk 1995

Things to remember!
¢  No fixed Protocol for rehab
¢  Modify Exercises by regular patient evaluation
¢  Task Specific and Functional Exercises more effective
¢  Rehabilitation greatly influenced by level of motivation of the patient and compliance to the exercise program
