Knee Arthroscopy Rehab

KNEE ARTHROSCOPY:
DEBRIDEMENT, PARTIAL MENISCECTOMY, LATERAL RELEASE

Melanie McNeal, PT, CSCS, CFT
for patients of
David Lintner, MD

Generally, following knee arthroscopy, an aggressive rehab approach can be taken. No major precautions or contra-indications are present and ROM and strength can be progressed as tolerated. This includes the following procedures: partial medial or lateral menisectomy, debridement of cartilage and joint surfaces, removal of a loose body, plica excision, and lateral release.

One primary goal following surgery is to gain full passive knee extension. This, along with neuro-muscular quad control, is the key to facilitate a normal gait pattern. Initially, focus should be on increasing VMO tone. Exercises should be geared toward quad strengthening in a pain-free range. Until swelling is minimal and the patient has a normal gait, prolonged standing and walking activities should be limited.

Patellar mobilizations and scar massage are both necessary to regain full ROM. Advancement of exercises and activities is based on quad tone. Some patients may be back to regular activities at 3-4 weeks while others may take significantly longer. It is important to find out the pre-op status of the patient as this will help determine how fast the patient will progress post-operatively.
Following a lateral release, a slightly longer rehabilitation program is sometimes necessary. It is common for patients to have a persistent, large hemarthrosis at the lateral-superior knee due to the fact that the lateral geniculate artery is often cut during surgery. It is imperative to keep the IT band stretched out post-operatively. The gluteus muscles should also be stretched due to their insertion site at the lateral hip. In addition to stretching and soft tissue mobilization, medial patellar glides are beneficial to prevent excessive scarring at the ITB. Initially, hip abduction may need to be avoided following a lateral release – if it is painful to perform. If the medial patello-femoral ligament was torn and repaired during surgery, restrictions on ROM are necessary. Consult with Dr. Lintner to make sure the proper precautions are taken with these patients.

ATS PROTOCOL
PHASE ONE

Weeks 1-2

Keys during phase one:

  • Gain full knee extension so patient can ambulate with normal gait
  • Neuro-muscular quad control – use biofeedback on VMO
  • Control swelling: Swelling inhibits quad firing and limits ROM; as long as there is a flexed knee gait, the more the patient ambulates, the more swelling will increase; therefore, limit activities and ambulation early in rehab.
  • Normal gait: patients will ambulate with flexed knee gait secondary to no quad control; have patient focus on quad contraction and full knee extension during stance phase of gait.

EXERCISES
STRENGTH AND NM CONTROL

  • Quad sets (10 X 10sec)– the more the better – at least 100/day
  • SLR – 4 way (initially avoid extension with HSG)
  • Multi-hip
  • Calf Raises
  • Shuttle/Total Gym – pain-free range

STRETCHING

  • Hamstring stretch – hold 30 seconds
  • Gastroc stretch with towel – hold 30 seconds
  • ITB stretch
  • Piriformis stretch

ROM

  • Goal during this phase is 0-90°
  • Manual patella mobs – especially superior/inferior
  • Seated heel slides using towel
  • Supine heel slides at wall if needed
  • Prone hangs if needed to gain full extension

BALANCE

  • Weight shifting
  • Single limb stance

GAIT

  • Cone walking – move to single crutch when ready and then d/c crutches when patient ambulates with N gait.

MODALITIES

  • EMS may be needed to facilitate quad if contraction cannot be voluntarily evoked
  • EGS may be needed to help control swelling and increase circulation
  • Ice should be used following exercise and initially every hour for 20 minutes

*Perform HEP 3X/Day

PHASE TWO

Weeks 2-6
By end of this phase, the patient should ambulate with N gait I, have good quad control, controlled swelling, and be able to ascend/descend stairs.

EXERCISES
STRENGTH

  • Quad sets are continued until swelling is gone and quad tone is good
  • SLR (4 way) add ankle weights when ready
  • Shuttle/Total gym – bilateral and unilateral- focus on weight distribution more on heel than toes to avoid overload on Patella tendon
  • Multi-hip – increase intensity as able
  • Closed chain terminal knee extension (TKE)
  • Leg Press
  • Step-ups – forward
  • Step-overs
  • Wall slides
  • Mini-squats – focus on even distribution of weight
  • Calf raises
  • Hamstring curls

CARDIO

  • Bicycle – do not perform until 110° of flexion is achieved – do NOT use bike to gain ROM. Perform daily and increase resistance as able to work quad.

EFX – increase resistance as able

STRETCHING

  • Continue with HS, calf, ITB, and piriformis stretching

ROM

  • Goal is 0-125°
  • Perform scar massage aggressively at portals
  • Prone hangs (do not add weight to ankle) w/BF
  • Heel slides – seated and/or supine
  • Continue with cycling, increasing duration and intensity

BALANCE

  • Single leg stance – even and uneven surface – focus on knee flexion
  • Plyoball – toss
  • Lateral cone walking with single leg balance between each cone
  • Foam roller or BAPS board balance work

GAIT

  • Cone walking – forward and lateral
  • D/C crutches when N gait

MODALITIES

  • Continue to use ice following exercise

*Continue with HEP

PHASE THREE

Weeks 6-12

Goals for this phase are full quad control and good quad tone; patient should be able to perform normal ADLs without difficulty.

Exercises will be advanced in intensity based on quad tone – a patient who continues to have poor quad tone must not be advanced to activities that require high quad strength such as squats and lunges

STRENGTH

  • Continue with above exercises, increasing intensity as able
  • Step-ups – forward and lateral; add dumbbells to increase I; focus on slow and controlled movement during the ascent and descent
  • Squats – Smith press or standing
  • Lunges – forward and reverse; add dumbbells or med ball
  • Hamstring curls
  • Swiss ball and foam roll hamstring exercises – supine bridge with knee flexion, bridge with HS curl
  • T-band hip flexion
  • Single leg squats
  • Russian dead lifts – bilateral and unilateral
  • Single leg wall squats
  • Initiate lateral movements and sports cord: lunges, forward, backward, or side-step with sports cord, lat step-ups with sports cord, step over hurdles.

ROM

  • Goal is 0-140°
  • Work to full ROM – continue with heel slides
  • BALANCE
  • Plyoball – toss – even and uneven surface
  • Squats on balance board/foam roll/airex
  • Steamboats – 4 way; even and uneven surface
  • Strength activities such as step-ups and lunges on airex

CARDIO

  • Cycle – increase intensity; single leg cycle maintaining 80 RPM
  • Jogging/Plyos: Based on quad tone, no swelling, and permission from Dr. Lintner, the patient can begin to jog at a slow to normal pace focusing on achieving normal stride length and frequency. Initiate jogging for 2 minutes, walking for 1 until this is comfortable for the patient and then progress the time as able. Jogging should first be performed on a treadmill or track (only straight-aways) and then progressed to harder surfaces such as grass and then asphalt or concrete. It is normal for the patient to have increased swelling as well as some soreness but this should not persist beyond one day or the patient did too much.
  • Jump rope and line jumps can be initiated when the patient is cleared to jog.
  • This can be done for time or repetitions and should be done bilaterally and eventually progressed to unilateral.

MODALITIES

  • Continue to use ice after exercise

*Continue with HEP at least 3X/week

PHASE FOUR

Weeks 12-24
Exercises for strengthening should continue with focus on high intensity and low repetitions (6-10) for increased strength.

Progress with stretching and strengthening program (2-3X/week)

Progress jogging speed and distance

Progress plyos: Sportsmetric program can be implemented

Bilateral and unilateral plyos on shuttle

Plyos can include squat jumps, tuck jumps, box jumps, depth jumps, 180 jumps, cone jumps, broad jumps, scissor hops

Leg circuit: squats, lunges, scissor jumps on step, squat jumps

Power skipping

Bounding in place and for distance

Quick feet on step – forward and side-to-side – use sports cord

Progress lateral movements – shuffles with sports cord; slide board

Ladder drills

Swimming – all styles

Focus should be on quality, NOT quantity

Landing from jumps is critical – knees should flex to 30° and should be aligned over second toe. Controlling valgus will initially be a challenge and unilateral hops should not be performed until this is achieved.

Initiate sprints and cutting drills.
Progression: Straight line, figure 8, circles, 45° turns, 90° cuts
Carioca
Sports specific drills
Biodex test

Single leg hop test

Biodex goals:

Peak Torque/BW Males Pk T/BS females

60°/s (%) 110-115 80-95

180°/s (%) 60-75 50-65

300°/s (%) 30-40 30-45
