What prehabilitation actually means before hip arthroscopy

If you have been told you need hip arthroscopy, the weeks before your operation are not simply a waiting period. They are an opportunity to actively prepare — and the evidence supports doing so.

Prehabilitation (prehab) is structured exercise carried out before surgery, with the specific aim of improving hip strength and movement quality ahead of the procedure. It is distinct from general fitness: the focus is on the neuromuscular patterns and muscle groups that will be called on during recovery.

Patients presenting for hip arthroscopy — most commonly for femoroacetabular impingement (FAI) or a labral tear — frequently arrive with pain-inhibited weakness and subtly altered movement habits. Pain changes how the hip is loaded over months, quietly reducing abductor strength and disrupting normal gait. Prehab addresses those deficits before they accompany you into the operating theatre.

The sections that follow cover what the evidence says about specific targets — hip abductor strength, proprioception, and neuromuscular control — and how a structured programme might be structured in practice.

What hip arthroscopy involves and the deficits it leaves behind

Hip arthroscopy accesses the joint through two or three small incisions, each roughly the width of a pencil. A camera and fine instruments are passed into the joint space — the leg is gently distracted to create room — allowing the surgeon to treat pathology inside the hip without the tissue disruption of open surgery.

The most common reason for the procedure is femoroacetabular impingement (FAI): a mismatch in the shape of the femoral head or the acetabular socket that causes the bones to pinch against one another during movement. Over time, this repeated impingement can tear the labrum — the ring of fibrocartilage that deepens the socket, improves joint stability, and distributes load across the hip. Arthroscopy addresses both problems in a single procedure: reshaping the bone and repairing the labrum, which reduces the risk of re-tear.

The functional consequences of living with FAI are cumulative. Pain during hip flexion limits how the joint is loaded, and the hip's neuromuscular system adapts quietly around it. Gluteus medius and gluteus minimus activity is suppressed, gait shifts to off-load the painful arc, and the joint's proprioceptive signals — its sense of position in space — become unreliable. By the time surgery is scheduled, these compensatory changes are often well established. They do not resolve automatically once the structural problem is corrected; that is precisely why prehabilitation has a role.

The evidence for prehabilitation in hip patients

The strongest direct evidence comes from a systematic review and meta-analysis of 48 randomised controlled trials (Punnoose et al. 2023), which found moderate-level evidence that prehabilitation improves outcomes in the pre-operative period for patients undergoing lower-limb orthopaedic surgery. In total hip replacement patients specifically, prehabilitation improved hip abductor strength and health-related quality of life scores before surgery; there is also weak certainty of evidence for reduced pre-operative pain.

A longitudinal dataset by Fortin et al. (2002) adds a different dimension to this picture: where the meta-analysis measures what prehab achieves in the weeks before the operation, the Fortin data captures what happens at the far end of the pathway. Patients with low pre-operative function were five times more likely to require assistance with daily living activities at 24 months post-surgery compared to those arriving at surgery in good functional condition. The two bodies of evidence together establish that the pre-surgical period carries long-term consequences — not just short-term preparation value. That said, the evidence for prehabilitation improving post-operative outcomes, as distinct from pre-operative function, remains less robust in certainty.

One limitation deserves to be stated plainly: the majority of prehabilitation RCTs involve total hip replacement patients, not hip arthroscopy. Direct evidence for arthroscopy-specific prehab protocols is limited. Clinicians applying prehabilitation in this setting draw on adjacent lower-limb evidence and adapt it to the arthroscopic context — accounting, for instance, for pain-limited hip flexion and the need to avoid aggravating impingement. The pre-operative window, however, consistently emerges as a meaningful intervention point across the evidence base, even where procedure-specific data are still developing.

Hip strength: which muscles to target and why

Seventeen muscles act on the hip joint, organised into four groups: gluteal, lateral rotators, adductors, and iliopsoas. Each group has a role in prehabilitation, but they are not equally urgent before hip arthroscopy.

The gluteus medius and gluteus minimus — the hip abductors — are the clinical priority. These muscles stabilise the pelvis during every step: without adequate abductor control, the pelvis drops to the opposite side when weight is taken on one leg, a pattern called Trendelenburg gait. That shift increases load across the hip joint and places added stress on surrounding soft tissue — significant when the joint is being prepared for surgery.

What makes pre-operative weakness difficult to detect is how it develops. Pain inhibition — the nervous system's reflex suppression of muscular activation in response to a painful joint — can reduce gluteal output before any visible muscle wasting occurs. Someone with FAI may feel no subjective sense of weakness, yet single-leg stance testing will often reveal reduced abductor control. This is a neurological adaptation rather than frank atrophy, and it is directly addressable through targeted prehabilitation.

Progressive resistance loading of the hip abductors and surrounding musculature is the core prehab tool for strength. A commonly cited training intensity is 70–75% of the maximum weight a person can lift for a single repetition (their one-repetition maximum, or 1RM) — a level broadly associated with meaningful strength adaptation. For hip arthroscopy patients, this is a target to work towards, not a starting point. Hip flexion-loaded exercises and impingement-provocative positions — such as loaded deep squats or hip flexion beyond 90 degrees — should be avoided or pain-guided throughout. This is the key modification that separates hip arthroscopy prehab from more general hip strengthening: the structural abnormality being treated must not be aggravated in the weeks before surgery corrects it.

Neuromuscular control: training proprioception and movement quality

Strength and neuromuscular control are related but distinct capacities. A muscle can generate adequate force in a controlled testing position yet still mis-time its activation when the joint is loaded unexpectedly — switching on a fraction too late, or failing to moderate load during an uneven step. That gap between raw strength and co-ordinated response is what neuromuscular control training targets.

In patients with FAI or labral pathology, proprioceptive function — the joint's ability to sense its own position, load, and movement — is commonly disrupted even before measurable strength loss appears. Pain alters the sensory signals from the joint capsule and surrounding tissue, and the nervous system adjusts its movement strategies accordingly. The result is compensatory patterns: small but consistent deviations in how the hip is loaded with each step, increasing soft-tissue stress on the very structures being prepared for surgery.

Single-leg balance on progressively unstable surfaces addresses this directly. Resistance exercises build force capacity; balance work demands that the hip's sensorimotor system respond in real time to unpredictable load. An example protocol drawn from MSK evidence suggests approximately 4 × 50 seconds per leg daily, progressing to less stable surfaces as pain and control allow. Movement quality trained through this work before surgery also establishes the neuromuscular patterns that post-operative rehabilitation will reinforce — making recovery a continuation of a familiar process rather than a restart from zero.

Starting a prehabilitation programme: what to do next

Supervised prehabilitation — guided by a physiotherapist familiar with hip pathology — is preferable to self-directed exercise, not because patients cannot begin independently, but because an initial assessment makes the programme safe and precisely targeted. A review of hip strength, proprioception, and gait quality before starting allows exercises to be matched to individual deficits rather than applied generically.

At a first physiotherapy appointment, useful questions include which movements are safe given the specific FAI morphology and where the pain-guided limits lie. The programme should be reviewed regularly in the weeks before surgery, with progressions adjusted as strength and control improve.

A clear red flag throughout is sharp groin pain or the reproduction of impingement symptoms during any exercise. That signals a need to modify the movement — not push through it. The joint is being prepared for surgery, not conditioned beyond its current anatomy.

Patients in Lincolnshire and the surrounding area can access hip specialist assessment at local consultation rooms in Grantham and Sleaford. Lincolnshire Hip is part of the MSK Doctors group and accepts patients without referral for hip assessment.

Even a few weeks of structured pre-operative exercise has value. Evidence supports meaningful functional gains within that window — the programme does not need to be lengthy to make a worthwhile difference before surgery.
