Hip arthroscopy is performed under general anaesthetic and through small incisions using a camera to visualize the inside of the hip joint. Using traction to pull the hip slightly out of joint and using a few small incisions (about 1 centimeter each) your surgeon will insert a camera into one incision, and small instruments through the other incisions.
What is the benefit of hip arthroscopy compared to open surgery?
It is much less invasive than traditional hip surgery. This means: smaller incisions, earlier rehabilitation, short hospital stay, early return to work and sport. Unfortunately, the range of conditions able to be treated by hip arthroscopy are limited, but there is a definite place for the procedure amongst the range of treatment options available for hip disease.
What conditions can be treated with hip arthroscopy?
Tear: the labrum of the hip is a cuff of thick tissue that surround the rim of
the hip socket. The labrum helps to support the hip joint, lubricates it and
acts as bumper between the ball and socket as the hip bends. When a labral
tear of the hip occurs, a piece of this tissue can become pinched in the joint
causing pain and catching sensations.
Pincer Hip Impingement: when the front edge of the hip socket overlaps the front of the hip joint too far, the ball can catch against the edge of the socket causing labral damage and damage to the cartilage at the edge of the hip socket. This is more common in women than men and may be able to be treated using hip arthroscopy in some cases.
Loose Bodies: loose bodies are pieces of cartilage that form within the joint. They look like small marbles floating within the joint space. These loose bodies can become caught within the hip during movements.
Hip Syndrome: snapping hip syndrome has several causes, some of which can be
treated with hip arthroscopy. If something is catching within the hip joint,
hip arthroscopy can be used to relieve this snapping. Also, hip arthroscopy can
be used to perform a psoas tendon release in cases of internal snapping hip
Damage: in patients with focal cartilage damage, meaning not widespread
arthritis, hip arthroscopy may be helpful. These patients may sustain an injury
causing a piece of cartilage to break away from the surface of the bone. These
patients may benefit from removal of that piece of cartilage.
Early Arthritis: this is a controversial topic, as patients who have arthritis pain generally will not benefit from a hip arthroscopy. The patients who tend to benefit have specific finding of impingement (pinching) within the hip joint, and may benefit from removal of the bone spurs causing this impingement. This is only possible in the very early stages of arthritis, and even then may not offer relief of symptoms.
What are the possible complications from hip arthroscopy?
The most concerning complications of hip arthroscopy have to do with several important nerves and blood vessels that surround the joint. Nerve injury is uncommon, but can be a significant problem. The most commonly affected nerves include the sciatic nerve, the femoral nerve, the lateral femoral cutaneous nerve (sensation to the thigh), and the pudendal nerve. Injury to any of the nerves can cause pain and weakness as well as other problems.Other possible complications from hip arthroscopy include potential injury to normal structures within the hip joint, infection, and continued pain after the surgery.
of these complications is low, but patients need to understand the potential
prior to undergoing a hip arthroscopy.It is estimated that 10% of patients will
have a complication or undergo an unsuccessful hip arthroscopy.
The benefit of hip arthroscopy is that the recovery is much simpler than for open hip surgery. Patients can typically put as much weight as tolerated on the hip immediately following surgery unless specifically restricted by your surgeon.In the first weeks after surgery, patients’ work on regaining motion around the joint, and gentle strengthening exercises. Typically, patients work with a physical therapist for assistance with these exercises and stretches.Most patients can begin light activities (cycling, swimming) within a few weeks. Athletes most often take about 12 weeks for recovery but there are specific procedures that may require a more lengthy rehabilitation.
Arthroscopy Rehabilitation Protocolhase
I - Initial phase
Goal: Regain range of motion within tolerance, decrease pain and swelling, neutralize muscle atrophy. Day of burgery: isometric gluteal sets, ankle pumps, heel slides.
Post-operative days 1-7, weight bearing with crutches, isometric quadriceps, gluteals, hamstrings, adductors and abductors, active assist range of motion all planes, hip mobilization and gentle joint distraction techniques, closed chain bridging, balance drills.
Phase II - Intermediate phase
Goal: Regain and build muscle strength, focus on symmetry/core strength. Post-operative weeks 2-3, wean crutches and normalize gait pat tern, increase range of motion limits, gentle progressive resistive exercises, closed chain single leg bridging, open chain hip 4-way, mobilization with movement, proprioceptive/balance work, stationary bike/aqua therapy.
Phase III - Advanced phase
Goal: Improve functional strength and endurance, core strength & stability. Post-operative weeks 4-6, continue flexibility exercises, progressively increase resistive and functional strengthening exercises, initiate sport specific exercises, gradual return to sport.
Note: Weight bearing may be limited after some surgical procedures with a hip arthroscopy, including: labral repair, Iliopsoas release, microfracture, capsulorraphy. Individual rehabilitation protocols will vary by patient and procedure, this information is simply a guide to the rehabilitation following hip arthroscopy in some patients.
