🦴 What Is an Anatomic Total Shoulder Replacement?

An anatomic total shoulder replacement (aTSA) involves replacing the damaged ball-and-socket joint of the shoulder with prosthetic components that replicate the shoulder’s natural structure. The surgery is typically performed to relieve pain and restore function in people with:

  • Osteoarthritis
  • Post-traumatic arthritis
  • Avascular necrosis
  • Intact or repairable rotator cuff tendons

Unlike a reverse shoulder replacement, aTSA relies on healthy rotator cuff muscles to control movement and stabilise the joint.

🩺 Before Surgery: How to Prepare

✅ Understand the Procedure

The procedure involves:

You’ll typically stay in hospital for 1–2 nights and begin physiotherapy soon after.

✅ Pre-Surgical Physiotherapy (Prehab)

Prehab helps set you up for a smoother recovery and has been shown to:

Your physio will focus on:

“Pre-operative physiotherapy can shorten hospital stays and improve early functional recovery.” — Moreside et al., 2019

✅ Set Up Your Home Environment

🛌 Sleeping After Shoulder Replacement

Getting restful sleep can be a challenge post-op. Try the following:

Tip: Practice your sleeping setup during the day so you’re prepared for night one.

📆 Recovery Timeline: What to Expect Week by Week

PhaseTimelineKey Goals
ProtectionWeeks 0–2Pain relief, healing, passive range of motion only
MobilisationWeeks 3–6Active-assisted ROM, start scapular control
Functional useWeeks 6–12Begin active ROM, resume light daily activities
Strengthening3–6 monthsProgressive resistance, restore function
Return to full activity6–12 monthsBuild endurance, sport/task-specific rehab

🏋🏻‍♂️ General Lifting Timeline

TimelineLifting Ability
0–6 weeksNo lifting with operated arm
6–12 weeksLight object handling (cutlery, remote), <1 kg
3–4 monthsGradual return to 1–3 kg (e.g. light bags)
4–6 monthsModerate household loads (~5 kg)
6+ monthsHeavier lifting as guided by physio/surgeon

Always check with your surgeon and physiotherapist before increasing load.

🏌🏼‍♀️ Returning to Daily Activities and Sports

ActivityTimeline Estimate
Driving6–8 weeks
Desk work2–4 weeks
Light housework6–12 weeks
Swimming/Golf4–6 months
Resistance Training3–5 months
Contact sports❌ Not recommended

Contact sports are generally avoided due to the high risk of dislocation or implant damage. In rare cases, return to modified low-contact activity may be considered under close supervision.

⚠️ Stiffness After Surgery: Why Early Rehab Matters

Some patients develop limited shoulder motion during recovery. This often results from:

Early physiotherapy is crucial to help maintain movement, reduce pain, and prevent long-term limitations. A proactive rehab plan is one of the most effective ways to reduce this risk.

⚠️ Nerve Injury: Rare but Important to Know

Nerve irritation after shoulder replacement is uncommon (1–3%), but possible. It may occur from surgical stretch or retraction and most often affects:

Most cases resolve over weeks to months with conservative care and physiotherapy. Severe or prolonged symptoms may need specialist review.

🧑‍⚕️ How Physiotherapy Supports Recovery

Physiotherapy is essential at every stage of shoulder replacement recovery. Your physiotherapist will:

We individualise rehab based on your goals and surgeon’s protocol, ensuring the best outcome over the long term.
