Manual Techniques for the Knee
A "Hands On" Approach to Restoring Function
Katie Cusack, PT, MHS, CMP
Manual Therapy
· Considered by many orthopedic physical therapists to be an important component in the evaluation and treatment of musculoskeletal disorders disorders. · Benefits have been documented in the literature supporting the use of manual therapy in conjunction with joint mobility and strengthening exercises.
Manual Therapy
· A term that encompasses a broad range of techniques. · Manual therapeutic techniques are used to relieve pain and to increase joint mobility mobility. · Such techniques may include soft tissue mobilization, massage, myofascial release, passive range of motion, joint mobilization, and manipulation.
Considerations
· Good understanding of the anatomy of the knee · Knowledge of knee joint biomechanics · Have already performed a complete evaluation of the knee. · Checked for any contra-indications
Anatomy
· Tibiofemoral Joint · Patellofemoral Joint · Superior Tibiofibular Joint

Osteokinematics
· Total range of motion in the healthy knee is from about 5-10 degrees of hyperextension to 140-150 degrees of extension
Tibiofemoral Arthrokinematics
During Knee Extension Open kinetic chain tibia glides anteriorly on the femur Closed kinetic chain femur glides posteriorly on the tibia.
During Knee Flexion Closed kinetic chain Open kinetic chain tibia glides posteriorly on femur glides anteriorly on the tibia. the femur
Screw Home Mechanism
From 20o knee flexion to full extension Open kinetic chain Closed kinetic chain tibia externally rotates femur rotates internally on a stable tibia From full knee extension to 20o flexion Open kinetic chain Closed kinetic chain tibia internally rotates femur rotates externally on a stable tibia
Patellofemoral Arthrokinematics
· During flexion at the tibiofemoral joint, the posterior motion of the tibia causes ligamentum patellae to pull the patella posteriorly and distally · During extension, the patella is pulled upward along the patellofemoral groove by the quads.
Superior Tib-fib Arthrokinematics
· The exact function of this joint is not fully understood and often overlooked. · As the knee moves into extension in an open kinetic chain position, the fibular head is p p pulled posterior as the lateral collateral ligament and biceps femoris becomes taut. · Knee flexion produces an anterior movement due to the relaxation of the lateral collateral ligament and biceps femoris tendon
Patella mobilizations
· Patient position: Supine in slight flexion · Technique: Therapist q p stands to the side of the patient and gently mobilizes the patella superiorly/inferiorly direction as well as medially/ laterally

Sidelying Medial Patella glide
· Patient position: Sidelying with knee flexed 200 or less · Technique: Place the q heel of your hand over the lateral border of the patella and glide medially
Sidelying Medial Patella Tilt
· Patient position: Sidelying with knee flexed · Technique: Place the q heel of your hand over the medial ½ of the patella and tilt the medial border posteriorly.
Mulligan Technique
· Mobilization with Movement (MWM) was developed by Brian Mulligan · Mulligan proposes that minor positional faults occur during injury or strain resulting in movement restrictions and/or pain · MWM is almost always performed at right angles to the plane of movement taking place.
Principles
· During assessment the therapist will identify one or more objective signs · A passive accessory joint mobilization is applied · Continuously monitor the patient's reaction to ensure no pain is recreated. · While sustaining the mobilization, the patient is asked to perform the objective sign
Principles
· The application of overpressure at the end of the available range is necessary for lasting improvement. · The patient undertakes 3 sets of 10 pain painfree reps of the previously provocative movement. · If there is no improvement, the therapist is performing the technique incorrectly or the technique is not indicated.
Knee Flexion MWM
Rotation in the Open Kinetic Chain Mobilization: Internal rotation of the tibia on the femur Movement: Knee flexion
Page 4 of 9
Knee Flexion MWM
Rotation in Closed Kinetic Chain Mobilization: Internal rotation of the tibia in CKC Movement: Knee flexion
Knee Flexion MWM
Side glide with belt assistance in prone Mobilization: Medial or lateral glide of the tibia through the mobilization belt Movement: Knee flexion
Knee Flexion MWM
Posterior Glide in Supine Mobilization: Posterior glide of the tibia Movement: Knee flexion
Knee Flexion MWM
Superior Tibiofibular Joint in CKC Mobilization: Anterior glide of fibula on stabilized tibia Movement: Knee flexion in partial weight bearing
Knee Extension MWM
Rotation in OKC Mobilization: External rotation of the tibia on stabilized femur Movement: Knee extension
Knee Extension MWM
Side glide in OKC Mobilization: Side glide g of the tibia on a stabilized femur Movement: Knee extension

Superior Tibiofibular glide in OKC Mobilization: Posterior glide of fibula on a stabilized tibia Movement: Knee extension
Knee Extension MWM

Conclusion
· There are numerous techniques used by physical therapists. · Manual therapy can be a beneficial adjunct to the treatment of the knee when attempting to increase range of motion or decrease pain.
